The ball pulling lever 52 is always urged to the right, and by sliding it to the left against the urging, the bottom opening formed on the bottom surface of the lower plate 50 is opened, and the bottom opening is opened. The ball naturally falls from the bottom opening and is discharged. The operation of the ball removing lever 52 is usually performed in a state where a box (generally referred to as "Senryobako") for receiving the balls discharged from the lower plate 50 is placed below the lower plate 50. An operation handle 51 is arranged on the right side of the lower plate 50 as described above, and an ashtray 53 is attached to the left side of the lower plate 50.

As shown in FIG. 2, in the game board 13, a large number of nails (not shown) for ball guidance and a windmill (movable member 310 are shown, and others are shown) on a base plate 60 cut into a substantially square shape in front view. (Not shown), rails 61, 62, general winning opening 63, first winning opening 64, second winning opening 640, first variable winning device 65, second variable winning device (not shown), through gate 67. , The variable display device unit 80 and the like are assembled, and the peripheral edge portion thereof is attached to the back surface side of the inner frame 12 (see FIG. 1). The base plate 60 is made of a light-transmitting resin material, and is formed so that the player can visually recognize various structures arranged on the rear surface side of the base plate 60 from the front side thereof. The general winning opening 63, the first winning opening 64, the second winning opening 640, the first variable winning device 65, the second variable winning device (not shown), and the variable display device unit 80 are formed on the base plate 60 by router processing. It is arranged in the through hole, and is fixed by a tapping screw or the like from the front side of the game board 13.

The front central portion of the game board 13 can be visually recognized from the front side of the inner frame 12 through the window portion 14c (see FIG. 1) of the front frame 14. Hereinafter, the configuration of the game board 13 will be described mainly with reference to FIG. 2.

An outer rail 62 formed by bending a strip-shaped metal plate into a substantially arc shape is planted on the front surface of the game board 13, and a strip-shaped metal plate is placed inside the outer rail 62 in the same manner as the outer rail 62. The arc-shaped inner rail 61 formed in 1 is planted. The inner rail 61 and the outer rail 62 surround the front outer periphery of the game board 13, and the game board 13 and the glass unit 16 (see FIG. 1) surround the front and back, so that the front of the game board 13 is surrounded by a ball. A game area in which the game is played is formed by the behavior of. The game area is the area in front of the game board 13 that is partitioned by the two rails 61 and 62 and the resin outer edge member 73 that connects the rails (a winning opening or the like is arranged and fired). This is the area where the rails flow down.

The two rails 61 and 62 are provided to guide the ball launched from the ball launching unit 112a (see FIG. 4) to the upper part of the game board 13. A return ball prevention member 68 is attached to the tip of the inner rail 61 (upper left portion in FIG. 2) to prevent the ball once guided to the upper part of the game board 13 from returning to the ball guide passage. Will be done. A return rubber 69 is attached to the tip of the outer rail 62 (upper right part in FIG. 2) at a position corresponding to the maximum flight portion of the ball, and the ball launched with a predetermined momentum hits the return rubber 69 and has momentum. Is dampened and bounced back toward the center.

In the lower left side of the front view (lower left side of FIG. 2) of the game area, first symbol display devices 37A and 37B including a plurality of LEDs as light emitting means and a 7-segment display are arranged. The first symbol display devices 37A and 37B display according to each control performed by the main control device 110 (see FIG. 4), and mainly display the gaming state of the pachinko machine 10. In the present embodiment, the first symbol display devices 37A and 37B are configured to be used properly depending on whether the ball has won the first winning opening 64 or the second winning opening 640. Specifically, when the ball wins the first winning opening 64, the first symbol display device 37A operates, while when the ball wins the second winning opening 640, the first The symbol display device 37B is configured to operate.

Further, the first symbol display devices 37A and 37B use LEDs to indicate whether the pachinko machine 10 is in the probabilistic change, the time reduction, or the normal state by the lighting state, or indicate whether the pachinko machine 10 is in the changing state or not by the lighting state. , Whether the stop symbol is a symbol corresponding to a probabilistic jackpot, a symbol corresponding to a normal jackpot, or a missed symbol is indicated by the lighting state, the number of reserved balls is indicated by the lighting state, and the round during the jackpot is indicated by the 7-segment display device. Display the number and error. It should be noted that the plurality of LEDs are configured so that the emission colors (for example, red, green, blue) of the respective LEDs are different, and the combination of the emission colors may suggest various gaming states of the pachinko machine 10 with a small number of LEDs. can.

In the pachinko machine 10, a lottery is performed when the first winning opening 64 and the second winning opening 640 have won a prize. In the lottery, the pachinko machine 10 determines whether or not it is a big hit (big hit lottery), and if it is determined to be a big hit, it also determines the type of the big hit. As the jackpot type determined here, 15R probability variation jackpot, 4R probability variation jackpot, and 15R normal jackpot are prepared. The first symbol display devices 37A and 37B not only indicate whether or not the lottery result is a big hit as a stop symbol after the end of the fluctuation, and if it is a big hit, a symbol corresponding to the jackpot type is shown. ..

Here, the "15R probability variation jackpot" is a probability variation jackpot in which the maximum number of rounds shifts to a high probability state after the jackpot of 15 rounds, and the "4R probability variation jackpot" is a jackpot with a maximum number of rounds of 4 rounds. It is a probabilistic jackpot that shifts to a high probability state after. Further, "15R normal jackpot" is a jackpot in which the maximum number of rounds is 15 rounds, and then the probability shifts to a low probability state, and the time is shortened during a predetermined number of fluctuations (for example, 100 fluctuations). be.

In addition, the "high probability state" refers to a state in which the probability of a jackpot is increased as an added value after the end of the jackpot, that is, during a so-called probability fluctuation (probability change), in other words, a game in which it is easy to shift to a special gaming state. It is the state of. The high-probability state (during probabilistic change) in the present embodiment includes a game state in which the winning probability of the second symbol, which will be described later, is increased and the ball is likely to win the second winning opening 640. The "low probability state" refers to a state in which the probability change is not in progress, and a state in which the jackpot probability is normal, that is, a state in which the jackpot probability is lower than that in the probability change state. In addition, in the "low probability state", the time saving state (time saving medium) is a state in which the jackpot probability is a normal state, and the jackpot probability remains the same and only the hit probability of the second symbol is increased to increase the second winning opening 640. It refers to the state of the game in which the ball is easy to win. On the other hand, when the pachinko machine 10 is in the normal state, it is a state of the game in which neither the probability change nor the time reduction is performed (the jackpot probability and the hit probability of the second symbol are not increased).

During the probability change and the time reduction, not only the probability of hitting the second symbol increases, but also the time when the electric accessory 640a attached to the second winning opening 640 is opened is changed, which is a longer time than during normal times. Set. When the electric accessory 640a is in the open state (open state), the ball wins the second winning opening 640 as compared with the case where the electric accessory 640a is in the closed state (closed state). It will be easy. Therefore, during the probability change or the time reduction, the ball can easily win the second winning opening 640, and the number of times the big hit lottery is performed can be increased.

In addition, during the probability change or the time reduction, the opening time of the electric accessory 640a attached to the second winning opening 640 is not changed, or in addition to changing the opening time, electric power is applied at one time. The change may be made so that the number of times that the accessory 640a is opened is increased from the normal time. Further, during the probability change or the time reduction, the hit probability of the second symbol is not changed, and the electric accessory 640a is opened at the time when the electric accessory 640a attached to the second winning opening 640 is opened and at one hit. At least one of the times may be changed. In addition, during the probability change or the time reduction, the time when the electric accessory 640a attached to the second winning opening 640 is opened and the number of times when the electric accessory 640a is opened per hit is not performed, and the second symbol is hit. Only the probability may be changed so as to be higher than the normal one.

In the game area, a plurality of general winning openings 63 are arranged in which 5 to 15 balls are paid out as prize balls when the balls are won. Further, a variable display device unit 80 is arranged in the central portion of the game area. The variable display device unit 80 is triggered by winning a prize (starting prize) in the first winning opening 64 and the second winning opening 640, and is synchronized with the variable display in the first symbol display devices 37A and 37B, and has a third symbol. It is composed of a third symbol display device 81 composed of a liquid crystal display (hereinafter simply abbreviated as "display device") that performs variable display, and an LED that variablely displays the second symbol triggered by the passage of a sphere of a through gate 67. A second symbol display device (not shown) is provided. Further, in the variable display device unit 80, a center frame 86 is arranged so as to surround the outer periphery of the third symbol display device 81.

The third symbol display device 81 is composed of a large 9-inch size liquid crystal display, and by controlling the display contents by the display control device 114 (see FIG. 4), for example, the upper, middle, and lower 3 Two symbol columns are displayed. Each symbol row is composed of a plurality of symbols (third symbol), and these third symbols are horizontally scrolled for each symbol row, and the third symbol is variably displayed on the display screen of the third symbol display device 81. It has become like. In the third symbol display device 81 of the present embodiment, the game state displayed by the control of the main control device 110 (see FIG. 4) is displayed by the first symbol display devices 37A and 37B, whereas the first of the third symbol display devices 81 is A decorative display is performed according to the display of the symbol display devices 37A and 37B. In addition, instead of the display device, for example, a reel or the like may be used to configure the third symbol display device 81.

The second symbol display device alternately lights the “○” symbol and the “×” symbol as the display symbol (second symbol (not shown)) each time the sphere passes through the through gate 67 for a predetermined time. It is a variable display. When the pachinko machine 10 detects that the ball has passed through the through gate 67, a winning lottery is performed. As a result of the winning lottery, if it is a winning, the symbol "○" is stopped and displayed on the second symbol display device after the variation display of the second symbol. Further, if the result of the winning lottery is a failure, the symbol "x" is stopped and displayed on the second symbol display device after the variation display of the third symbol.

In the pachinko machine 10, when the variation display in the second symbol display device is stopped at a predetermined symbol (in the present embodiment, the symbol “○”), the electric accessory 640a attached to the second winning opening 640 is used for a predetermined time. It is configured to be activated (opened) only.

The time required for the variation display of the second symbol is set to be shorter during the probability change or the time reduction than when the game state is normal. As a result, during the probability change and the time reduction, the variation display of the second symbol is performed in a short time, so that the winning lottery can be performed more than during the normal time. Therefore, since the chances of winning in the winning lottery increase, it is possible to give the player many opportunities to open the electric accessory 640a of the second winning opening 640. Therefore, it is possible to make it easy for the ball to win the second winning opening 640 during the probability change and the time saving.

In addition, during the probability change or the time reduction, the second winning opening 640 can be reached during the probability change or the time reduction by other methods such as increasing the opening time and the number of times of opening the electric accessory 640a per hit. When the ball is in a state where it is easy to win a prize, the time required for the variable display of the second symbol may be constant regardless of the gaming state. On the other hand, when the time required for the variation display of the second symbol is set to be shorter than the normal time during the probability change or the time reduction, the hit probability may be constant regardless of the gaming state, or one hit. The opening time and the number of times of opening the electric accessory 640a may be constant regardless of the gaming state.

The through gate 67 is assembled to the game board on the right side in the area below the variable display device unit 80, and among the balls fired on the game board, a part of the balls flowing down to the right side of the game board can pass through. It is configured in. When the ball passes through the through gate 67, a winning lottery for the second symbol is performed. After the winning lottery, variable display is performed on the second symbol display device, and if the winning lottery result is a winning symbol, a symbol "○" is displayed as a stop symbol of the variable display, and if the winning lottery result is incorrect. For example, a symbol of "x" is displayed as a stop symbol of the variable display.

The number of times the ball has passed through the through gate 67 is held up to a total of four times, and the number of held balls is displayed by the above-mentioned first symbol display devices 37A and 37B and on the second symbol holding lamp (not shown). Is also lit and displayed. Four second symbol holding lamps are provided for the maximum number of holding lamps, and are symmetrically arranged below the third symbol display device 81.

The variation display of the second symbol is performed by switching the lighting and non-lighting of a plurality of lamps in the second symbol display device as in the present embodiment, as well as the first symbol display devices 37A, 37B and the third. It may be performed by using a part of the symbol display device 81. Similarly, the second symbol holding lamp may be turned on by a part of the third symbol display device 81. Further, the maximum number of reserved balls for the passage of the balls of the through gate 67 is not limited to 4, but may be set to 3 times or less, or 5 times or more (for example, 8 times). Further, the number of through gates 67 assembled is not limited to one, and may be a plurality (for example, two). Further, the assembly position of the through gate 67 is not limited to the right side of the variable display device unit 80, and may be, for example, the left side of the variable display device unit 80. Further, since the number of reserved balls is indicated by the first symbol display devices 37A and 37B, the lighting display may not be performed by the second symbol holding lamp.

Below the variable display device unit 80, a first winning opening 64 in which a ball can win a prize is arranged. When a ball wins a prize in the first winning opening 64, the first winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main control device 110 is caused by turning on the first winning opening switch. A big hit lottery is made in (see FIG. 4), and the display according to the lottery result is shown by the first symbol display device 37A.

On the other hand, on the right side of the front view of the first winning opening 64, a second winning opening 640 in which the ball can win is arranged. When the ball wins the second winning opening 640, the second winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and the main control device 110 is turned on due to the turning on of the second winning opening switch. A big hit lottery is made in (see FIG. 4), and the display according to the lottery result is shown on the first symbol display device 37B.

In addition, the first winning opening 64 and the second winning opening 640 are also one of the winning openings in which five balls are paid out as prize balls when the balls are won. In the present embodiment, the number of prize balls paid out when a ball wins in the first winning opening 64 and the number of prize balls paid out when a ball wins in the second winning opening 640 are configured to be the same. , The number of prize balls paid out when a ball wins in the first winning opening 64 and the number of prize balls paid out when a ball wins in the second winning opening 640, for example, a ball to the first winning opening 64 The number of prize balls paid out when a prize is won may be three, and the number of prize balls paid out when a ball is won in the second winning opening 640 may be configured as five.

An electric accessory 640a is attached to the second winning opening 640. The electric accessory 640a is configured to be openable and closable, and normally the electric accessory 640a is in a closed state (reduced state), making it difficult for the ball to win a prize in the second winning opening 640. On the other hand, when the symbol "○" is displayed on the second symbol display device as a result of the variation display of the second symbol performed when the ball passes through the through gate 67, the electric accessory 640a is in the open state (enlarged). State), and the ball is in a state where it is easy to win a prize in the second winning opening 640.

As described above, during the probabilistic change and the time reduction, the probability of hitting the second symbol is higher than during the normal time, and the time required for the variation display of the second symbol is short. The symbol "" is easily displayed, and the number of times that the electric accessory 640a is in the open state (enlarged state) increases. Further, during the probability change and the time reduction, the time during which the electric accessory 640a is released is also longer than during the normal operation. Therefore, during the probability change and the time reduction, it is possible to create a state in which the ball is more likely to win the second winning opening 640 as compared with the normal time.

Here, the probability of winning a jackpot is the same in both the low probability state and the high probability state when the ball wins in the first winning opening 64 and when the ball wins in the second winning opening 640. However, the probability of becoming a 15R probability variation jackpot as the type of jackpot selected in the case of a jackpot is higher when the ball wins the second winning opening 640 than when the ball wins the first winning opening 64. It is set. On the other hand, the first winning opening 64 does not have an electric accessory as in the second winning opening 640, and the ball is in a state where it can always win a prize.

Therefore, in normal times, the electric accessory attached to the second winning opening 640 is often in a closed state, and it is difficult to win the second winning opening 640. Then, the ball is fired so that the ball passes to the left side of the variable display device unit 80 (so-called "left-handed"), and by winning the first winning opening 64, many chances of a big hit lottery are obtained and the big hit is obtained. It is advantageous for the player to aim at that.

On the other hand, during the probability change or the time reduction, by passing the ball through the through gate 67, the electric accessory 640a attached to the second winning opening 640 is likely to be opened, and the second winning opening 640 is likely to be won. Therefore, the ball is launched toward the second winning opening 640 so that the ball passes to the right of the variable display device 80 (so-called "right-handed"), and the electric accessory is opened by passing through the through gate 67. At the same time, it is advantageous for the player to aim for a 15R probability variation jackpot by winning the second winning opening 640.

As described above, the pachinko machine 10 of the present embodiment fires a ball at the player according to the gaming state of the pachinko machine 10 (whether it is in the probabilistic change, in the time saving, or in the normal state). You can change the method of "left-handed" and "right-handed". Therefore, the player can enjoy the game because the way of hitting the ball can be changed.

The first symbol display device 37A or the first symbol display device 37B is turned on so that the stop symbol corresponding to the jackpot is displayed on the third symbol display device 81 to indicate the occurrence of the jackpot. After that, the gaming state transitions to a special gaming state (big hit) where the ball is easy to win. As this special game state, the specific winning opening 65a, which is normally closed, is opened for a predetermined time (for example, until 30 seconds have passed or until 10 balls are won).

The specific winning opening 65a is closed after a lapse of a predetermined time, and after the closing, the specific winning opening 65a is opened again for a predetermined time. The opening / closing operation of the specific winning opening 65a can be repeated up to 15 times (15 rounds), for example. The state in which this opening / closing operation is performed is a form of a special gaming state that is advantageous to the player, and a larger amount of prize balls than usual is paid out to the player as a game value (game value). Is done.

Mainly includes a disk portion 452c formed between the two, and a sliding wall portion 452d which is an arc-shaped wall surface slid on the arc-shaped recess 453c of the reversing gear 453 (see FIG. 20).

Since the gear teeth 452a are always meshed with the transmission gear 451, the two-layer gear 452 is constantly rotated when the slide member 420 slides up and down.

The lower layer of the two-layer gear 452 is composed of a region in which the dividing gear tooth 452b is engraved and a region in which the sliding wall portion 452d is formed. A starting gear tooth 452b1 larger than the gear tooth 452b2 is engraved. The recesses 452b3 and 452b4 (see FIG. 20) formed on both sides of the starting gear teeth 452b1 as receiving portions of the gear teeth are formed deeper than the recesses between the gear teeth of the intermediate gear teeth 452b2. As a result, the starting gear teeth 453b1 formed to be larger than the intermediate gear teeth 453b2 of the reversing gear 453, which will be described later, can be accepted in good meshing (a state in which the gear teeth are deeply meshed). Therefore, even if the size of the gear teeth is different for each tooth, the toothing relationship between the two-layer gear 452 and the reversing gear 453 can be kept good.

The recesses 452b3 and 452b4 formed on both sides of the starting gear tooth 452b1 serve as a receiving portion of the starting gear tooth 453b1 of the reversing gear 453 (see FIG. 23B). Of the recessed portions 452b3 and 452b4, the side close to the sliding wall portion 452d is referred to as the first recessed portion 452b3, and the opposite side of the first recessed portion 452b3 is referred to as the second recessed portion 452b4.

The gear tooth 452b is formed smaller than the starting gear tooth 452b1 of the dividing gear tooth 452b and larger than the intermediate gear tooth 452b2. As a result, as will be described later, the misalignment between the starting gear teeth 452b1 of the double-layer gear 452 and the starting gear teeth 453b1 of the reversing gear 453 at the start of meshing is suppressed, and the accuracy of rotation during continuous meshing is improved. Can be made to.

The start of meshing means the time when the starting gear teeth 452b1 of the two-layer gear 452 and the reversing gear 453 start to come into contact with each other, and is not limited to the case where the gear teeth start to come into contact with each other. In the present embodiment, it means that the starting gear teeth 452b1 of the two-layer gear 452 and the engaging protrusion receiving portion 453d of the reversing gear 453 are in contact with each other.

Further, the continuous meshing means a state in which the intermediate gear teeth 452b2 and 453b2 are meshed after the starting gear teeth 452b1 and 453b1 are meshed.

As a method of enlarging the starting gear tooth 452b1, a method of enlarging the tooth width (the length along the axial direction of the gear) is also conceivable. However, in the present embodiment, the tooth widths of the starting gear teeth 452b1 and the intermediate gear teeth 452b2 are formed to be the same because the two-layer gear 452 can be easily formed into a two-layer structure, and the tooth thickness (dimensions in the continuous direction of the teeth) is formed. ) And the teeth are enlarged.

The disk portion 452c is formed by being superposed on the gear teeth of the transmission gear 451 adjacent to the two-layer gear 452 and the gear teeth of the reversing gear 453 adjacent to the two-layer gear 452 in an axial view (FIG. 21B). reference). As a result, when the transmission gear 451 and the reversing gear 453 move in the axial direction, the transmission gear 451 and the reversing gear 453 are prevented from wobbling due to the respective gear teeth coming into contact with the disk portion 452c. It is possible to suppress further movement of the transmission gear 451 and the reversing gear 453.

The reversing gear 453 is a member that reverses the half-moon member 460 by being meshed with and rotated by the two-layer gear 452, and the main body portion 453a formed into a tubular body through which the tubular main body 462a of the half-moon member 460 can be inserted.

It mainly includes an engaging protrusion receiving portion 453d and a locking protrusion 453e projecting in the radial direction from a position where the outer peripheral surface of the main body portion 453a is divided into three equal parts.

The reversing gear teeth 453b are engraved with starting gear teeth 453b1 larger than the intermediate gear teeth 453b2 (gear teeth other than both ends) (tooth thickness and tooth injury) at both ends thereof. The recessed portion 453b3 formed between the starting gear tooth 453b1 and the engaging protrusion receiving portion 453d as a receiving portion of the gear tooth is deeper than the recess formed between the gear teeth of the intermediate gear tooth 453b2. It is formed. As a result, the starting gear teeth 452b1 formed larger than the intermediate gear teeth 452b2 of the two-layer gear 452 can be accepted in good meshing (a state in which the gear teeth are deeply meshed). Therefore, even if the size of the gear teeth is different for each tooth, the toothing relationship between the two-layer gear 452 and the reversing gear 453 can be kept good.

The arcuate recess 453c is a portion that comes into contact with the sliding wall portion 452d of the two-layer gear 452, and is formed with a radius of curvature substantially the same as the radius of the sliding wall portion 452d.

The locking protrusion 453e is fitted to the arcuate wall portion 461c formed on the main body portion 461 of the half-moon member 460 in such a manner that it cannot rotate relative to each other. As a result, the reversing gear 453 and the half-moon member 460 are integrally rotated.

The front cover 466 is a member that is fastened and fixed to the front side of the main body portion 461 and accommodates each member of the half moon member 460 between the main body portion 461, and the slide plate portion 463b of the claw member 463 is inserted through the front cover 466. An elongated slide hole 466a is bored.

The drive lever 467 is an insertion hole 467b (FIG. 13) formed at a position corresponding to a long plate-shaped lever portion 467a (see FIG. 13) extending radially outward and a fastening hole 462d of the central gear 462. 13) and mainly.

The lever portion 467a (see FIG. 13) is a portion pushed by the slide rack 442, and the center gear 462 is rotated by pushing the lever portion 467a by the slide rack 442.

It will be described back to FIG. 10 to FIG. The drive device 470 is arranged so as to be raised to the front side in the central portion of the base member 410, and is fastened and fixed to the base member 410 with a fastening plate portion 471 and a drive motor 472 fastened and fixed to the fastening plate portion 471. And a drive gear 473 that is inserted into the drive shaft of the drive motor 472.

The fastening plate portion 471 includes a pair of regulation wall portions 471a and 471b formed in an arc shape in cross section along the outer shape of the motor case of the drive gear 472 and extending to the front side, and one of the regulation wall portions 471a ( The inner side in the assembled state is extended to a substantially intermediate position of the motor case, and the other regulation wall portion 471b (outer side in the assembled state) is extended longer than the extended end of the one regulation wall part 471a. These pair of regulation wall portions 471a and 471b are used as guides when the drive motor 472 is pulled out from the fastening plate portion 471.

The drive gear 473 is arranged to face the rack gear 422a of the pair of slide members 420 from both sides, and is meshed from both sides.

Next, the outline of the movement of the pair of slide members 420 of the composite operation unit 400 will be described with reference to FIGS. 16 to 19. 16 and 18 are partial front views of the combined operation unit 400, FIG. 17 (a) is a partial cross-sectional view of the combined operation unit 400 in the XVIIa-XVIIa line of FIG. 16, and FIG. 17 (b) is a partial cross-sectional view. It is a partial cross-sectional view of the composite operation unit 400 after moving the drive device 470 from FIG. 17 (a), and FIG. 19 (a) is a partial cross-sectional view of the composite operation unit 400 in the XIXa-XIXa line of FIG. 19 (b) is a partial cross-sectional view of the combined operation unit 400 after the drive motor 472 is separated from the drive gear 473 from FIG. 19 (a). Note that FIGS. 16 and 17 show a state in which the pair of slide members 420 are arranged in the retracted position, and FIGS. 18 and 19 show a state in which the pair of slide members 420 are arranged in the overhanging position.

As shown in FIGS. 16 and 18, the pair of slide members 420 sandwich the drive gear 473 of the drive device 470 between the transmitted leg portions 422. At this time, the rack gear 422a of the transmitted leg portion 422 arranged to face each other across the drive gear 473 is meshed with the single drive gear 473. As a result, the drive gear 473 is rotated by the drive motor 472, so that the transmitted leg portions 422 arranged to face each other across the drive gear 473 are slid and moved in synchronization with each other.

That is, in the state where the slide member 420 is arranged in the retracted position (see FIG. 16), the drive gear 473 is rotated clockwise in the front view, so that the upper slide member 420 moves downward and the lower slide member 420. Are moved upwards at constant speed with each other. At this time, the drive motors 472 arranged in pairs on the left and right are synchronously controlled, and the pair of slide members can be stably slid.

Further, the weights of the pair of slide members 420 are applied in opposite directions to the drive gear 473. For example, the drive gear 473 on the right side in the front view is weighted from the upper slide member 420 in the direction of rotating the drive gear 473 clockwise, and the drive gear 473 is counterclockwise from the lower slide member 420. Weight is applied in the direction of rotation. As a result, if the weights of the pair of slide members 420 are made equal to each other, even if the power of the drive motor 472 is cut off, the drive gear 473 can be kept stopped due to the balance of the weights of the pair of slide members 420. Therefore, even if the power of the drive motor 472 is cut off when the pair of slide members 420 are arranged at an arbitrary position, the pair of slide members 420 can be kept stopped at that position.

The pair of transmitted legs 422 of the slide member 420 are meshed with the drive gear 473 from the same direction. That is, for example, the pair of left and right transmitted leg portions 422 of the upper slide member 420 are meshed with the drive gear 473 from the right side in the front view, and the pair of left and right transmitted leg portions 422 of the lower slide member 420 are left and right. Both are engaged with the drive gear 473 from the left side when viewed from the front.

As a result, even if one of the transmitted legs 422 meshed with the drive gear 473 suddenly moves (for example, even if the distance from the driven gear 473 meshed with the drive gear 473 increases). The other transmitted leg 422 connected via the one transmitted leg 422 and the main body 421 is moved in the same direction as the one transmitted leg 422. That is, since the drive gear 473 is moved away from the driven gear 473 to be meshed with, it is possible to suppress applying a large load to the drive gear 473 meshed with the other leg to be transmitted 422.

Here, for example, one of the transmitted leg portions 422 of the slide member 420 is meshed with the drive gear 473 from the front right side, and the other transmitted leg portion 422 is meshed with the drive gear 473 from the front view left side. Then, one of the transmitted legs 422 is moved from the drive gear 473 in a direction in which the distance increases, so that the other transmitted leg 422 is pressed against the drive gear 473. As a result, a large load is applied to the drive gear 473 meshed with the other leg to be transmitted 422.

On the other hand, in the present embodiment, since it is possible to prevent a large load from being applied to the drive gear 473 as described above, the proper meshing relationship between the drive gear 473 and the rack gear 422a of the transmitted leg portion 422 is appropriate. Can be achieved. Further, the shapes of the pair of slide members 420 can be made equivalent, and the members can be standardized.

As shown in FIG. 19A, the drive gear 473 and the front side wall portion 422c interfere with each other in the front-rear direction (the vertical direction of the paper surface in FIG. 19A). On the other hand, in a state where the pair of slide members 420 are arranged in the retracted position (see FIG. 16), the drive gear 473 can be visually recognized in a state of being spaced from the outer shape of the cutout portion 422d in the front view. The positional relationship between the slide member 420 and the drive gear 473, which "can visually recognize the drive gear 473 with a distance from the outer shape of the notch portion 422d in front view," will be described as a specific phase position.

Therefore, in a state where the pair of slide members 420 are arranged at the retracted position (specific phase position) which is the end of the movable range, the drive gear 473 can be pulled out through the notch portion 422d formed in the transmitted leg portion 422. .. As a result, the drive gear 473 can be replaced without removing the slide member 420 from the base member 410 (see FIG. 17B). Therefore, the maintainability of the drive gear 473 can be improved.

Here, the pair of slide members 420 are arranged so as to face each other with the drive gear 473 interposed therebetween, and are meshed with the drive gear 473 by the rack gears 422a of the respective legs to be transmitted 422. In this state, since it is necessary to form a state in which both of the pair of slide members 420 are similarly arranged in the retracted position (see FIG. 16), the drive gear 473 and the rack gear 422a are meshed with arbitrary gear teeth. It's not good. That is, the relationship between the drive gear 473 and the rack gear 422a of the pair of slide members 420 is fixed so that they mesh with each other (the representative gear tooth of the rack gear 422a that comes into contact with the representative gear tooth of the drive gear 473 at the time of meshing). Is defined) to form a proper tooth alignment.

A cutout portion 422d of the slide member 420 can be used to form the proper meshing state. That is, in the notch portion 422d, as described above, in a state where the pair of slide members 420 are arranged at the retracted position (see FIG. 16), the representative circle slightly larger than the tooth tip circle of the drive gear 473 rotates the drive gear 473. When the axis and the central axis are aligned, it is formed in a portion projected on the front side wall portion 422c in the front-rear direction (vertical direction on the paper surface of FIG. 16).

Therefore, in a state where the pair of slide members 420 are arranged in the retracted position (see FIG. 16), the notch portions 422d are arranged so as to face each other. In this state, the drive gear 473 is moved through the notch portion 422d (moved in the direction perpendicular to the paper surface of FIG. 16), so that the drive gear 473 and the rack gear 422a can be meshed with each other in an appropriate meshing state.

When the pair of slide members 420 are arranged in the retracted position (specific phase position), the pair of slide members 420 are blocked from moving outward in the vertical direction (the upper slide member 420 is the upper slide member, and the lower slide member 420 is the lower slide member. 420 blocks further downward movement). That is, when the slide member 420 is randomly moved to the retracted position side, the slide member 420 is stopped at least at the retracted position (movement resistance increases).

Therefore, in adjusting the position of the slide member 420 when the maintenance worker replaces the drive gear 473, even if the slide member 420 is randomly moved in the retracting direction, the slide member 420 is at the retracted position (specific phase) which is the end of the movable range. Position) is stopped. As a result, the drive gear 473 can be easily taken out through the notch portion 422d, and the drive gear 473 can be easily meshed with the rack gear 422a of the pair of slide members 420 in that state. Therefore, maintainability can be improved.

The arrangement of the drive device 470 will be described with reference to FIG. 17 (a). As described above, since the notch portion 422d is formed in the pair of slide members 420, the drive device 470 in the assembled state is fastened and fixed to the base member 410 with the pair of slide members 420 arranged in the retracted position. be able to. Thereby, the degree of freedom of arrangement of the drive device 470 can be improved.

That is, when the cutout portion 422d is not formed in the front side wall portion 422c of the slide member 420 (for example, when the front side wall portion 422c is formed in the entire region of the rack gear 422a), the drive device 470 is used as the base member 410. Even if it is attempted to be assembled, the drive gear 473 comes into contact with the front side wall portion 422c, and the drive device 470 cannot be assembled to the base member 410. Therefore, the drive device 470 has to be arranged on the opposite side of the front side wall portion 422c, and the degree of freedom of arrangement of the drive device 470 is low.

On the other hand, in the present embodiment, the notch portion 422d is formed in the front side wall portion 422c. Therefore, by moving the drive gear 473 in the front-rear direction through the notch portion 422d, the drive device 470 is moved to the slide member 420. It can be arranged on the front side (the side on which the front side wall portion 422c is arranged). Therefore, the degree of freedom in arrangement of the drive device 470 can be improved.

Further, a front side wall portion 422c of the slide member 420 is formed in the layer between the drive gear 473 and the drive motor 472, and by moving the slide member 420 from the retracted position, the drive gear 473 and the front side wall portion 422c are moved back and forth. It can be overlapped in a directional view (FIG. 16 vertical view on paper). Thereby, when replacing the drive device 470, it is possible to select whether to remove the drive motor 472 and the drive gear 473 together, or to remove only the drive motor 472 while leaving the drive gear 473.

That is, the drive motor 472 and the drive gear 473 can be separated by pulling out the drive motor 472 while keeping the drive gear 473 in contact with the front side wall portion 422c of the slide member 420 (see FIG. 19B). .. As a result, the drive motor 472 can be replaced while maintaining the meshed state between the drive gear 473 and the rack gear 422a of the transmitted leg portion 422. Therefore, before and after the replacement of the drive motor 472, it is possible to eliminate the need for re-meshing adjustment of the drive gear 473 and the rack gear 422a of the transmitted leg portion 422, and it is possible to improve maintainability.

At this time, the drive gear 473 overlaps with the front side wall portion 422c of the pair of transmitted leg portions 422 arranged so as to face each other with the drive gear 473 in between in the front-rear direction (see FIG. 18 in the vertical direction on the paper) (see FIG. 18). Therefore, when the drive gear 473 is pulled out from the drive motor 472, a force is applied to the drive gear 473 from at least two points arranged so as to face each other across the rotation shaft. Therefore, tilting of the drive motor 472 with respect to the drive gear 473 is suppressed.

Further, when the drive motor 472 is pulled out from the fastening plate portion 471, the drive motor 472 can be moved along the regulation wall portions 471a and 471b while being pressed against the regulation wall portions 471a and 471b, so that the drive motor 472 can be moved. It is possible to prevent the axis from tilting with respect to the drive gear 473. As a result, it is possible to prevent the drive gear 473 from being deformed.

As shown in FIG. 19A, one of the regulation wall portions 471a is formed so as to retract from the front end surface of the motor case of the drive motor 472 to the fastening plate portion 471 side. As a result, the drive motor 472 can be pulled out with the extended end of one of the regulation wall portions 471a as the fulcrum S. That is, since the extended end of one regulation wall portion 471a and the side surface of the drive motor 472 are arranged adjacent to each other, the extended end of one regulation wall portion 471a is used as a fulcrum S and the side surface of the drive motor 472 (FIG. 19). In (a), the action point W is shown inside the drive motor 472 for easy understanding), and the distance between the fulcrum S and the action point W when a force is applied to the drive motor 472 is the shortest. Can be. Thereby, depending on the setting of the force point, the force required for pulling out the drive motor 472 can be suppressed. Note that FIG. 19A illustrates the relationship between the fulcrum S and the point of action W and a virtual lever.

Further, the drive motor 472 can be pulled out while pressing the drive motor 472 against the other regulation wall portion 471b arranged to face the one regulation wall portion 471a. As a result, it is possible to suppress the degree of inclination of the drive motor 472 with respect to the drive gear 473 when the drive motor 472 is pulled out.

As shown in FIG. 19A, the other regulation wall portion 471b is formed so as to project forward (upper in FIG. 19A) from the extended end portion of the one regulation wall portion 471a. As a result, when the drive motor 472 is pulled out with one regulation wall portion 471a as the fulcrum S, the drive motor 472 is driven from the other regulation wall portion 471b in the state W1 in which the action point W is closest to the other regulation wall portion 471b. A force can be applied in the direction of pushing back to the point of action W. Therefore, the other regulating wall portion 471b can prevent the drive motor 472 from moving in the direction perpendicular to the drive shaft. As a result, it is possible to reliably prevent the drive motor 472 from moving in a direction away from one of the regulation wall portions 471a when the drive motor 472 is pulled out.

Next, with reference to FIG. 20, the two-layer gear 452 involved in the rotation of the half-moon member 460 of the composite operation unit 400 will be described. 20 (a) is a front view of the double-layer gear 452, and FIG. 20 (b) is a rear view of the double-layer gear 452.

As shown in FIGS. 20 (a) and 20 (b), the two-layer gear 452 is a gear member in which different gear teeth are engraved on the front side and the back side with the disk portion 452c as a boundary. As shown in FIG. 20A, the starting gear tooth 452b1 adjacent to the sliding wall portion 452d is formed to be larger than the intermediate gear tooth 452b2. Therefore, as will be described later, the starting gear tooth 452b1 can be provided with durability that can withstand a collision (contact) with the reversing gear 453. In the present embodiment, only the starting gear tooth 452b1 adjacent to the sliding wall portion 452d is formed to be large, and the intermediate gear tooth 452b2 is formed to be small, so that durability is improved and material cost is suppressed. It is possible to achieve both.

The two-layer gear 452 includes a recessed bottom wall portion 452e as a wall surface forming the bottom of the first recessed portion 452b3 and the second recessed portion 452b4, and a push-back rib 452f connecting the recessed bottom wall portion 452e and the ring-shaped rib. , Equipped with.

Here, the second recessed portion 452b4 is required to have a sufficient depth as a recess for receiving the starting gear tooth 453b1 of the reversing gear 453 (see FIG. 23), while the first recessed portion 452b3 is engaged with the reversing gear 453. It is a recess into which the projecting receiving portion 453d enters. Therefore, the depth of the second recessed portion 452b4 is not required, but in the present embodiment, the depths of the first recessed portion 452b3 and the second recessed portion 452b4 are formed to be substantially the same. As a result, the amount of heat shrinkage of the resin material in the vicinity of the first recessed portion 452b3 and the second recessed portion 452b4 at the time of molding the two-layer gear 452 can be made uniform, and the moldability of the two-layer gear 452 can be improved. can.

As shown in FIG. 20A, a space is formed in a region surrounded by the sliding wall portion 452d, the wall portion formed by the tooth bottom of the intermediate gear tooth 452b2, and the recessed bottom wall portion 452e. At this time, since the sliding wall portion 452d and the recessed bottom wall portion 452e are formed to have substantially the same plate thickness, it is possible to suppress the occurrence of sink marks peculiar to resin molding. In addition, the material cost of the resin material can be suppressed.

Here, the recessed bottom wall portion 452e is not always necessary to secure the function of the two-layer gear 452. On the other hand, the recessed bottom wall portion 452e is formed in such a manner that the starting gear teeth 452b1 and the sliding wall portion 452d are connected to each other. Therefore, the impact when the starting gear tooth 452b1 comes into contact with the reversing gear 453 can be dispersed (see FIG. 23B).

The push-back rib 452f is connected to the recessed bottom wall portion 452e of the second recessed portion 452b4. Here, the direction of the force line of the force F generated when the reversing gear 453 is brought into contact with the starting gear tooth 452b1 (see FIG. 23B) is directed toward the pushback rib 452f. As a result, even when a space is formed in the region surrounded by the sliding wall portion 452d of the two-layer gear 452, the wall portion formed by the tooth bottom of the intermediate gear tooth 452b2, and the recessed bottom wall portion 452e, the push-back rib 452f Therefore, the resistance to the force F can be improved. Therefore, it is possible to prevent the starting gear tooth 452b1 from being deformed by the impact at the time of contact.

As shown in FIG. 20B, the gear teeth 452a are formed around the two-layer gear 452. Since the gear teeth 452a are always meshed with the transmission gear 451 (see FIG. 21B), the two-layer gear 452 is constantly rotated when the slide member 420 slides up and down (see FIG. 21A). ..

Next, with reference to FIGS. 21 to 26, the details of the movement of the composite operation unit 400, that is, the operations of the slide member 420 and the half-moon member 460 that are moved by transmitting the driving force of the driving device 470 will be described. do. 21 to 26 show the operation of the combined operation unit 400 in chronological order. In addition, in FIGS. 21 to 26, the illustration of the back cover 430 is omitted for ease of understanding.

21 (a) and 22 (a) are rear views of the composite operation unit 400, and FIGS. 21 (b) and 22 (b) are rear views of the double-layer gear 452 and the reversing gear 453. Note that FIG. 21 shows a state in which the pair of slide members 420 are arranged in the retracted position, and FIG. 22 shows that the pair of slide members are slid by a predetermined distance from the retracted position and the reversing gear 453 engages with each other. The state in which the end portion of the shape receiving portion 453d is arranged to face the first recessed portion 452b3 of the two-layer gear 452 is shown. Further, in FIGS. 21 (b) and 22 (b), in the two-layer gear 452, the dividing gear tooth 452b and the sliding wall portion 452d are shown by solid lines, and the gear teeth 452a and the disk portion 452c are shown by imaginary lines. NS.

As shown in FIG. 21B, in a state where the pair of slide members 420 are arranged in the retracted position, in the reversing gear 453, the arcuate recess 453c of the engaging protrusion receiving portion 453d slides the two-layer gear 452. It is circumscribed to the wall portion 452d on a surface. As a result, the posture of the reversing gear 453 can be maintained.

In this case, the mechanical fitting of the engaging protrusion receiving portion 453d and the sliding wall portion 452d acts as a holding mechanism for maintaining the posture of the reversing gear 453. Therefore, in order to maintain the posture of the reversing gear 453, it is not necessary to dispose of another member such as an elastic spring.

Further, the sliding wall portion 452d of the double-layer gear 452 and the engaging protrusion receiving portion 453d of the reversing gear 453 come into contact with each other on both sides of a straight line connecting the rotating shaft of the double-layer gear 452 and the rotating shaft of the reversing gear 453. Will be done. Therefore, the rotation of the reversing gear 453 can be prevented regardless of the rotation direction of the reversing gear 453, and the posture of the reversing gear 453 can be maintained.

As shown in FIG. 22B, when the pair of slide members 420 are moved, the transmission gear 451 meshed with the permanent rack gear 414a of the base member 410 among the plurality of transmission gears 451 is rotated. Along with the rotation, the two-layer gear 452, which is meshed with the other transmission gear 451 and the transmission gear 451 by the gear teeth 452, is also rotated. On the other hand, since the reversing gear 453 is not meshed with the two-layer gear 452, it is maintained in the same posture as the retracted position.

While the pair of slide members 420 are moving, the arcuate recess 453c of the engaging protrusion receiving portion 453d receives sliding friction from the sliding wall portion 452d of the two-layer gear 452. In the present embodiment, the arcuate recess 453c of the engaging protrusion receiving portion 453d is circumscribed on the sliding wall portion 452d of the two-layer gear 452 to prevent the sliding friction from being concentrated in one place. The frictional force can be dispersed throughout the arcuate recess 453c. As a result, it is possible to prevent a large force from being locally applied to the reversing gear 453 from the two-layer gear 452. Further, by increasing the number of places where the two-layer gear 452 and the reversing gear 453 come into contact with each other, the effect of maintaining the posture of the reversing gear 453 can be improved.

23 (a) and 23 (b) are rear views of the two-layer gear 452 and the reversing gear 453. Note that FIG. 23 (a) shows a state in which the two-layer gear 452 is rotated counterclockwise by a predetermined amount from FIG. 22 (b), and FIG. 23 (b) shows the state of FIG. 23 (a). A state in which the two-layer gear 452 is further rotated counterclockwise by a predetermined amount from the state is shown. Further, in FIG. 23, in the two-layer gear 452, the dividing gear teeth 452b and the sliding wall portion 452d are shown by solid lines, and the gear teeth 452a and the disk portion 452c are shown by imaginary lines.

As described above in FIG. 22B, the end of the engaging protrusion 453d of the reversing gear 453 is a double-layer gear before the reversing gear 453 is brought into contact with the starting gear teeth 452b1 of the double-layer gear 452. It is arranged so as to face the first recessed portion 452b3 of 452.

At this time, since the end portion of the engaging protrusion receiving portion 453d arranged to face the first recessed portion 452b3 is not in contact with the two-layer gear 452, the effect of maintaining the posture of the reversing gear 453 is released, and at least It is possible to rotate in the rotation direction of 1 (clockwise in FIG. 22B).

As shown in FIG. 23A, the double-layer gear 452 is rotated counterclockwise by a predetermined amount in FIG. 23A, so that the reversing gear 453 is brought into contact with the starting gear teeth 452b1 of the double-layer gear 452. It is rotated before it is turned on. That is, the reversing gear 453 is rotated by the sliding friction applied from the sliding wall portion 452d of the two-layer gear 452 to the engaging protrusion receiving portion 453d of the reversing gear 453. At this time, the reversing gear 453 is rotated in such a manner that the engaging protrusion receiving portion 453d is brought into the first recessed portion 452b3 of the two-layer gear 452.

That is, the reversing gear 453 was slightly rotated by the sliding friction applied from the sliding wall portion 452d of the double-layer gear 452 to the engaging protrusion receiving portion 453d of the reversing gear 453 (see FIG. 23A). It comes into contact with the starting gear teeth 452b1 of the layer gear 452 (see FIG. 23B). As a result, it is possible to suppress the impact when the reversing gear 453 and the starting gear teeth 452b1 of the two-layer gear 452 come into contact with each other.

As shown in FIG. 23B, the position where the starting gear teeth 452b1 of the double-layer gear 452 and the reversing gear 453 start to come into contact with each other is a straight line connecting the rotating shaft of the double-layer gear 452 and the rotating shaft of the reversing gear 453. The two-layer gear 452 is formed at a position (upper in FIG. 23B) returned to the opposite side in the rotation direction.

As a result, the force applied to the reversing gear 453 when the starting gear teeth 452b1 of the two-layer gear 452 and the reversing gear 453 start to come into contact with each other is a component that points in the rotation direction of the reversing gear 453 and the rotation shaft of the reversing gear 453. It is transmitted separately from the ingredients that are suitable for gears. Therefore, it is possible to prevent the reversing gear 453 from rotating too much at the start of contact between the starting gear teeth 452b1 of the two-layer gear 452 and the reversing gear 453.

That is, when the starting gear teeth 452b1 of the two-layer gear 452 start to come into contact with the reversing gear 453, the plurality of teeth do not mesh with each other from the beginning. Therefore, when the force applied in the rotation direction of the reversing gear 453 when abutting the starting gear teeth 452b1 of the two-layer gear 452 is excessive, the reversing gear 453 rotates at a speed higher than the rotation speed of the two-layer gear 452 ( May move). In that case, the meshing of the two-layer gear 452 and the reversing gear 453 may fail.

On the other hand, according to the present embodiment, a force applied from the two-layer gear 452 to the reversing gear 453 at the start of contact is also generated in a direction perpendicular to the rotation direction of the reversing gear 453 (direction toward the rotation axis). , The rotational resistance of the reversing gear 453 can be temporarily increased. That is, the rotational resistance can be increased by pressing the reversing gear 453 against the rotating shaft. As a result, it is possible to prevent the reversing gear 453 from rotating too much at the start of contact of the two-layer gear 452 with the starting gear teeth 452b1.

Further, since the starting gear teeth 452b1 and 453b1 are formed to be larger than the gear teeth 452a of the two-layer gear 452, it is possible to prevent the two-layer gear 452 and the reversing gear 453 from coming off at the start of meshing. ..

Here, since the play (backlash) formed becomes larger as the gear teeth become larger, the larger the teeth, the larger the deviation of the positional relationship (phase relationship) between the gears to be meshed from the middle can be tolerated. become. That is, when the teeth of the gears are miniaturized, even if the positional relationship (phase relationship) between the gears to be meshed is slightly shifted, there is a possibility that the teeth to be meshed are shifted by one tooth.

In the present embodiment, the double-layer gear 452 has more play (backlash) generated between the transmission gear 451 to which the driving force of the drive device 470 (see FIG. 10) is transmitted and the gear teeth 452a of the double-layer gear 452. The play (backlash) generated between the starting gear tooth 452b1 and the starting gear tooth 453b1 of the reversing gear 453 becomes larger. That is, the phase relationship shift of the two-layer gear 452 that occurs in relation to the transmission gear 451 is smaller than the phase relationship shift that occurs between the two-layer gear 452 and the reversing gear 453, and is acceptable. As a result, it is possible to prevent tooth misalignment at the start of meshing between the two-layer gear 452 and the reversing gear 453.

When the two-layer gear 452 begins to come into contact with the reversing gear 453 in the rotational direction, the starting gear teeth 452b1 of the two-layer gear 452 begin to come into contact with the engaging protrusion receiving portion 453d of the reversing gear 453. That is, the engaging protrusion 453d is used as a substitute for the gear tooth that begins to mesh with the starting gear tooth 452b1. Thereby, the durability of the reversing gear 453 can be improved.

That is, the engaging protrusion 453d on which the arcuate recess 453c is formed is not a portion that has a role of engaging with the gear teeth of the two-layer gear 452, but a reversing gear by abutting on the outer peripheral surface of the two-layer gear 452. It is a part of the role of maintaining the posture of 453. Therefore, unlike the gear teeth, the size is not limited according to the size of the gear teeth on the mating side. Further, it is desirable that the portion of the two-layer gear 452 that is brought into contact with the engaging protruding receiving portion 453d and the reversing gear 453 at the start of contact is large and durable, and the engaging protruding receiving portion 453d is used as that portion. By using it, the durability of the reversing gear 453 can be improved.

When the slide member 420 is moved by the driving force of the driving device 470 (see FIG. 10), the transmission gear 451 meshed with the permanent rack gear 414a is rotated, and the two-layer gear 452 is rotated accordingly. That is, the drive device 470 and the two-layer gear 452 are not directly meshed with each other, and at least the transmitted leg portion 422 meshed with the drive gear 473 is interposed between the drive device 470 and the two-layer gear 452. do. As a result, the impact at the time of contact between the starting gear teeth 452b1 of the two-layer gear 452 and the reversing gear 453 is transmitted to the drive device 470 in a relaxed state. Therefore, it is possible to prevent the drive device 470 from being damaged by the impact at the time of contact.

24 (a) and 25 (a) are rear views of the composite operation unit 400, and FIGS. 24 (b) and 25 (b) are rear views of the double-layer gear 452 and the reversing gear 453. In FIG. 24, a state in which the pair of half-moon members 460 are rotated by a predetermined amount from the state of FIG. 22 (a) is shown, and in FIG. 25, the pair of half-moon members 460 are respectively rotated from the state of FIG. 22 (a). The state immediately after the rotation of 180 degrees is completed is shown in the figure. Further, in FIGS. 24 (b) and 25 (b), in the two-layer gear 452, the dividing gear tooth 452b and the sliding wall portion 452d are shown by solid lines, and the gear teeth 452a and the disk portion 452c are shown by imaginary lines. NS.

As shown in FIG. 24B, in a state where the half-moon member 460 is rotated, the intermediate gear teeth 452b2 of the two-layer gear 452 and the intermediate gear teeth 453b2 of the reversing gear 453 are meshed with each other.

In the present embodiment, the starting gear teeth 452b1 of the two-layer gear 452 are formed to be larger than the intermediate gear teeth 452b2. Therefore, the durability of the starting gear tooth 452b1 that comes into contact with the reversing gear 453 at the start of contact with the reversing gear 453 is improved, and damage to the double-layer gear 452 can be prevented.

Further, as shown in FIG. 24B, the double-layer gear 452 and the reversing gear 453 are meshed with the intermediate gear teeth 452b2 and 453b2, so that the backlash occurs when the meshing continues rather than when the meshing starts. Can be made smaller. As a result, the rotation of the reversing gear 453 when the meshing is continued can be made smooth. Therefore, it is possible to improve the durability of the starting gear teeth 452b1 that collide with each other at the start of meshing and to improve the smoothness of rotation of the reversing gear 453.

Further, since the intermediate gear teeth 452b2 of the two-layer gear 452 are formed smaller than the gear teeth 452a, the intermediate gear teeth 452b2 of the two-layer gear 452 and the intermediate gear teeth 453b2 of the reversing gear 453 mesh with each other in the circumferential direction. The error (play) of is smaller than the meshing error between the gear teeth 452a and the transmission gear 451. As a result, the accuracy of the operation of the reversing gear 453 when the meshing is continued can be maintained below the meshing error between the gear teeth 452a and the transmission gear 451.

As shown in FIG. 25, when the half-moon member 460 finishes rotating 180 degrees, the engagement between the two-layer gear 452 and the reversing gear 453 is released, and the sliding wall portion 452d of the two-layer gear 452 and the circle of the reversing gear. The arc-shaped recess 453c is brought into contact with the surface. Therefore, the posture of the reversing gear 453 is maintained, and the locking protrusion 453e (see FIG. 12) and the arcuate wall portion 461c (see FIG. 15) of the reversing gear 453 are fitted to each other so as not to rotate relative to each other. The posture of is also maintained.

Next, with reference to FIG. 26, the operation of the claw member 463 of the half-moon member 460 will be described. 26 (a) and 26 (b) are partial rear views of the combined operation unit 400.

In FIG. 26, the permanent rack gear 414a of the base member 410 is partially omitted so that the limited rack gear 414b can be visually recognized and the portion is magnified. Further, FIG. 26A shows a state immediately before the starting gear tooth 441a of the deformed gear 441 comes into contact with the starting gear tooth 414b1 of the limited rack gear 414b, and FIG. 26B shows the slide rack 442 moving. The state of reaching the end is shown.

The meshing of the deformed gear teeth 441 and the limited rack gear 414b becomes defective unless the deformed gear 441 comes into contact with the limited rack gear 414b in an appropriate posture. That is, if the deformed gear 441 comes into contact with the limited rack gear 414b in a posture in which the starting gear teeth 441a of the deformed gear 441 and the starting gear teeth 414b1 of the limited rack gear 414b are in contact with each other, the teeth are satisfactorily meshed. On the other hand, for example, when the gear teeth of the deformed gear 441 other than the starting gear teeth 441a and the starting gear teeth 414b1 of the limited rack gear 414b come into contact with each other, a poor meshing occurs in the middle of the meshing. , The rotation of the deformed gear 441 cannot be continued. In this case, the slide movement of the slide member 420 is also stopped, so that the slide member 420 malfunctions.

In the present embodiment, the slide rack 442 is maintained to the left and right outward by the urging force of the urging spring 442c. The deformed gear 441 receives a force from the slide rack 442 via the transmission gear 443. Therefore, the posture of the deformed gear 441 can be maintained in the above-mentioned appropriate posture.

As shown in FIG. 26B, the deformed gear 441 is meshed with the limited rack gear 414b and rotated, so that the transmission gear 443 is rotated and the slide rack 442 is moved. The slide rack 442 comes into contact with the drive lever 467 in the middle of movement, and the drive lever 467 rotates. Since the drive lever 467 is fastened and fixed to the center gear 462 (see FIG. 15) of the half-moon member 460, the center gear 462 rotates when the drive lever 467 rotates. As a result, the crank gear 464 is rotated (see FIG. 14), and the claw member 463 is moved in the projecting direction. Therefore, the claw member 463 can be moved in conjunction with the movement of the slide member 420.

Next, the combined operation unit 2400 according to the second embodiment will be described with reference to FIGS. 27 and 28.

In the first embodiment, the case where the cutout portion 422d of the transmitted leg portion 422 is arranged to face the front side of the drive gear 473 while the slide member 420 is arranged in the retracted position has been described, but the second embodiment has been described. In the combined operation unit 2400 in the above, the cutout portion 2422d of the transmitted leg portion 2422 is arranged to face the front side of the drive gear 473 while the slide member 2420 is moving from the retracted position to the overhanging position. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

27 and 28 are front views of the pair of slide members 2420. Note that FIG. 27 shows a state in which the pair of slide members 2420 are arranged in the retracted position, and FIG. 28 shows the start gear teeth 452b1 and the start of the second gear group 450 in which the pair of slide members 2420 are moved from the retracted position. The state in which the gear 453b1 (see FIG. 23B) begins to come into contact with the gear 453b1 is illustrated. Further, the illustration of the drive device 470 is omitted for ease of understanding.

As shown in FIG. 27, in a state where the pair of slide members 2420 are arranged in the retracted position, they are covered on the front side of the drive gear 473 (the front side of the paper in FIG. 27) on the front side of the rack gear 422a in the tooth width direction. The front side wall portion 2422c is overlapped.

As shown in FIG. 28, a pair of slide members 2420 are arranged at positions where the starting gear teeth 452b1 of the two-layer gear 452 and the starting gear teeth 453b1 of the reversing gear 453 (see FIG. 23B) start to come into contact with each other. In the state, the notch portion 2422d is formed on the front side (front side of the paper in FIG. 27) of the drive gear 473. The notch portion 2422d is formed in a circular shape slightly larger than the tooth tip circle of the drive gear 473.

As shown in FIG. 28, the drive gear 473 can be visually recognized in a state of being separated from the outer shape of the notch portion 2422d in a front view (specific phase position). Therefore, the drive gear 473 can be pulled out through the notch portion 2422d formed in the transmitted leg portion 2422, whereby the drive gear 473 can be replaced without removing the slide member 2420 from the base member 2410. Therefore, the maintainability of the drive gear 473 can be improved.

In the present embodiment, the specific phase position is set in a state where the pair of slide members 2420 are moved from the retracted position and the starting gear teeth 452b1 and the starting gear teeth 453b1 (see FIG. 23A) of the second gear group 450 start to come into contact with each other. Therefore, the maintenance worker can move the slide member 2420 to a specific phase position by relying on the increase in resistance when moving the slide member 2420.

That is, when the slide member 2420 is moved, the transmission gear 451 (see FIG. 24A) is always meshed with the permanent rack gear 414a of the base member 2410. Therefore, when the rotation resistance of the transmission gear 451 increases, it can be grasped as the movement resistance of the slide member 2420. Here, since the transmission gear 451 is meshed with the two-layer gear 452, the resistance generated when the two-layer gear 452 and the reversing gear 453 start meshing is transmitted to the transmission gear 451. Then, the resistance to rotation of the transmission gear 451 increases, so that the movement resistance of the slide member 2420 increases. As a result, the maintenance worker can move the slide member 2420 to a specific phase position by relying on the increase in the movement resistance of the slide member 2420.

Here, since the front side wall portion 2422c does not overlap with the drive gear 473 at the specific phase position, the effect of bringing the front side wall portion 2422c into contact with the drive gear 473 and suppressing the wobbling of the drive gear 473 during rotation is weakened.

In the present embodiment, a specific phase position (a state in which the notch portion 2422d matches the drive gear 473) is formed during the movement of the pair of slide members 2420, that is, during the rotation of the drive gear 473. Therefore, when the drive gear 473 approaches the specific phase position, the drive gear 473 has a sufficient speed in the rotation direction (vertical axis direction). Therefore, the wobbling of the drive gear 473, which tends to occur at a specific phase position, can be alleviated by the momentum in the rotation direction of the drive gear 473.

The base member 2410 includes a triangular protrusion 2415 projecting from the center side (center side in FIG. 27) in the assembled state. It is possible to easily move the pair of slide members 2420 to a specific phase position by relying on the triangular protrusion 2415.

Here, in the maintenance of the gaming machine 13, when the drive motor 472 is removed together with the drive gear 473, it is necessary to arrange the slide member 2420 at a specific phase position. However, since the drive motor 472 is arranged on the front side in a manner of hiding the slide member 2420 (see FIG. 9), it is difficult to visually recognize the state in which the notch portion 2422d coincides with the drive gear 473 from the front side. be. Therefore, it is difficult to arrange the slide member 2420 at a specific phase position.

On the other hand, since the triangular protrusion 2415 is arranged at a position visible from the front side, it is possible to easily align the slide member 2410 by relying on the triangular protrusion 2415 for maintenance. In the present embodiment, when the pair of slide members 2420 are arranged at a specific phase position, the triangular protrusion 2415 and the triangular pattern formed at the end of the slide member 2420 form a series of patterns. This makes it easy for the maintenance worker to remove the drive gear 473 for maintenance.

Next, the two-layer gear 3452 and the reversing gear 3453 according to the third embodiment will be described with reference to FIGS. 29 and 30.

In the first embodiment, the case where the starting gear teeth 452b1 and 453b1 of the two-layer gear 452 and the reversing gear 453 are formed to be large in the direction of the rotation axis, that is, the case where the tooth depth and the tooth thickness are increased has been described. In the two-layer gear 3452 and the reversing gear 3453 according to the third embodiment, the starting gear teeth 3452b1 and 3453b1 are formed to have the same shape as the other gear teeth when viewed in the direction of the rotation axis, while being formed to be large in the axial direction. That is, a large tooth width is formed. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

29 (a) is a front view of the double-layer gear 3452, FIG. 29 (b) is a bottom view of the double-layer gear 3452, and FIG. 29 (c) is a side view of the double-layer gear 3452. ..

As shown in FIG. 29, the two-layer gear 3452 is arranged adjacent to the sliding wall portion 452d and has a large tooth width formed on the starting gear tooth 3452b1 and the starting gear tooth 3452b1 on the tooth root side. Circumferential rib 3452e extending from the side surface in the circumferential direction along the concentric circles of the two-layer gear 3452 and fixed to the front end surface of the intermediate gear tooth 452b2 near the starting gear tooth 3452b1 and the starting gear. It mainly includes a radial rib 3452f that extends from the radial side surface of the tooth 3452b1 toward the rotation axis and is fixed to the front end surface of the main body portion of the two-layer gear 3452.

The starting gear tooth 3452b1 has substantially the same tooth depth and tooth thickness as the intermediate gear tooth 452b2, but the tooth width is formed larger than that of the intermediate gear tooth 452b2. As a result, the rigidity of the starting gear tooth 3452b1 can be improved, and it is possible to prevent the starting gear tooth 3452b1 from being damaged at the start of meshing with the reversing gear 3453.

The circumferential rib 3452e is formed to be the widest in the axial direction of the two-layer gear 3452 at the side surface of the starting gear tooth 3452b1, that is, the extension base point, and the width is gradually shortened as the distance from the starting gear tooth 3452b1 increases. That is, as shown in FIG. 29 (b), it is visually recognized as a substantially triangular shape when viewed from the bottom. The circumferential rib 3452e can improve the rigidity of the starting gear teeth 3452b along the circumferential direction of the two-layer gear 3452, and can prevent the starting gear teeth 3452b1 from bending in the rotational direction.

Further, the circumferential rib 3452e extends to the intermediate gear tooth 452b2 in the vicinity of the starting gear tooth 3452b1 (up to two adjacent to the starting gear tooth 3452b1 in the present embodiment). This makes it possible to generate a force that pulls the tooth root of the intermediate gear tooth 452b2 toward the starting gear tooth 3452b1 by using the circumferential rib 3452e.

That is, when the intermediate gear tooth 452b2 near the starting gear tooth 3452b1 and the reversing gear 3453 mesh with each other, the deformation (deformation toward the direction away from the starting gear tooth 3452b1) that occurs in the intermediate gear tooth 452b1 is reduced to the circumferential rib 3452e. Can be suppressed by

The circumferential rib 3452e is fixed only to the intermediate gear tooth 452b2 near the starting gear tooth 3452b1 because the intermediate gear tooth 452b2 located at a position away from the starting gear tooth 3452b1 reverses after the rotation becomes steady. By being meshed with the gear 3453.

That is, when the intermediate gear tooth 452b2 (for example, the intermediate gear tooth 452b2 near the middle of the pair of starting gear teeth 3452b1) separated from the starting gear tooth 3452b1 is meshed with the reversing gear 3453, the rotation is already in a steady state. , The reversing gear 3453 has a sufficient rotational speed. Therefore, the force received by the intermediate gear tooth 452b2 from the reversing gear 3453 is small, and reinforcement by the circumferential rib 3452e is unnecessary.

The radial rib 3452f extends from the radial side surface of the starting gear tooth 3452b1 toward the rotation axis and is fixed to the front end surface of the main body of the two-layer gear 3452, so that the starting gear tooth The radial rigidity of 3452b1 can be improved. As a result, the reversing gear 3453 meshed with the two-layer gear 3452 is moved in the axial direction and rattles, so that the front end portion (upper end of FIG. 29B) of the starting gear tooth 3452b1 is forced toward the rotation shaft. Even if it receives, it is possible to prevent the starting gear tooth 3452b1 from falling. Therefore, the durability of the starting gear tooth 3452b1 can be improved.

30 (a) is a front view of the reversing gear 3453, FIG. 30 (b) is a bottom view of the reversing gear 3453, and FIG. 30 (c) is a side view of the reversing gear 3453.

As shown in FIG. 30, the reversing gear 3453 extends along the concentric circles of the reversing gear 3453 from the side surface of the starting gear tooth 3453b1 adjacent to the arcuate recess 453c and the tooth root side of the starting gear tooth 3453b1. Along with this, a circumferential rib 3453f fixed to the main body of the reversing gear 3453 is mainly provided.

The starting gear tooth 3453b1 has substantially the same tooth depth and tooth thickness as the other intermediate gear teeth 453b2, while the tooth width is formed larger than that of the other intermediate gear teeth 453b2. Thereby, the rigidity of the starting gear tooth 3453b1 can be improved.

The circumferential rib 3453f is formed to be the widest in the axial direction on the side surface of the starting gear tooth 3453b1, that is, at the extension base point, and the width is gradually shortened as the distance from the starting gear tooth 3453b1 increases. That is, as shown in FIG. 30B, it is visually recognized as a substantially triangular shape when viewed from the bottom. The circumferential rib 3453f can prevent the starting gear tooth 3453b1 from bending in the rotational direction.

Further, the circumferential rib 3453f extends toward the engaging protrusion receiving portion 453d adjacent to the starting gear tooth 3453b1. As a result, the rigidity of the starting gear tooth 3453b1 in the direction in which the force is applied from the two-layer gear 3452 (the direction from the starting gear tooth 3453b1 toward the adjacent engaging protrusion 453d) is improved. Therefore, the durability of the starting gear tooth 3453b1 can be improved.

Next, the two-layer gear 4452 and the reversing gear 4453 according to the fourth embodiment will be described with reference to FIGS. 31 and 32.

In the first embodiment, the case where the starting gear teeth 452b1 of the two-layer gear 452 are formed to be large in the direction of the rotation axis, that is, the case where the tooth depth and the tooth thickness are increased has been described. In the two-layer gear 4452, the starting gear teeth 4452b1 are formed to have the same shape as the other gear teeth when viewed in the direction of the rotation axis, while the tooth width is formed to be large, and the intermediate gear teeth 4452b2 sandwiched between the starting gear teeth 4452b1. The tooth width is formed in such a manner that the tooth width is shortened as the distance from the starting gear tooth 4452b1 is increased. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

31 (a) is a front view of the double-layer gear 4452, FIG. 31 (b) is a bottom view of the double-layer gear 4452, and FIG. 31 (c) is a view of XXXIc-XXXIc of FIG. 31 (b). It is sectional drawing of the two-layer gear 4452 in line.

As shown in FIG. 31, the two-layer gear 4452 includes a pair of starting gear teeth 4452b1 adjacent to the sliding wall portion 452d, an intermediate gear tooth 4452b2 formed between the starting gear teeth 4452b1, and a starting gear. It mainly includes a plate-shaped portion 4452e that is covered on the front side surface of the tooth 4452b1 and the intermediate gear tooth 4452b2.

As shown in FIG. 31B, the tooth width of the dividing gear tooth 4452b composed of the starting gear tooth 4452b1 and the intermediate gear tooth 4452b2 is maximum in the starting gear tooth 4452b1, and the tooth width of the intermediate gear tooth 4452b2 is started. As the distance from the gear tooth 4452b1 increases, the distance from the gear tooth 4452b1 is shortened in a stepwise manner with reference to the starting gear tooth 4452b1.

The plate-shaped portion 4452e is formed so as to project from the tooth bottom side of the dividing gear tooth 4452b to a position equivalent to the tip circle when viewed from the front, and is overlaid on the front side surface of the dividing gear tooth 4452b. The plate-shaped portion 4452e is formed in a manner of drawing a smooth curve in bottom view according to the formation position of the front side surface of the dividing gear tooth 4452b (see FIG. 31 (b)).

Here, consider a case where the front side surface of the dividing gear tooth 4452b is formed on the same plane, and the plate-shaped portion 4452e is also formed on the plane. In this case, the disc portion 452c and the plate-shaped portion 4452e are used in order to increase the allowable amount of the reversing gear 4453 being displaced in the axial direction of the double-layer gear 4452 at the start of meshing between the reversing gear 4453 and the two-layer gear 4452. If the distance from the gear is increased, the axial position of the rotating reversing gear 4453 cannot be determined. On the other hand, if an attempt is made to accurately determine the axial position of the rotating reversing gear 4453, the reversing gear 4453 is slightly displaced in the axial direction at the start of meshing, so that the reversing gear 4453 moves to the outer periphery of the plate-shaped portion 4452e. It may come into contact with the surface and cause poor meshing.

On the other hand, in the present embodiment, the axial misalignment (upward in FIG. 31B), which may occur before the reversing gear 4453 is meshed with the two-layer gear 4452, is set as the meshing start position. It can be tolerated to the maximum in the vicinity of the starting gear tooth 4452b1 which is.

Further, the plate-shaped portion 4452e is formed in a manner of drawing a smooth curve in which the distance from the disc portion 452c is shortened as the plate-shaped portion 4452e is separated from the starting gear tooth 4452b1 in the bottom view (see FIG. 31B). Therefore, when the reversing gear 4453 is brought into contact with the plate-shaped portion 4452e, the axial position of the reversing gear 4453 can be further corrected as the teething progresses (moving the reversing gear 4453 downward (FIG. 31 (b)). Can be done). Therefore, the axial misalignment between the two-layer gear 4452 and the reversing gear 4453 at the time of meshing can be corrected as the meshing progresses.

32 (a) is a front view of the reversing gear 4453, FIG. 32 (b) is a bottom view of the reversing gear 4453, and FIG. 32 (c) is a view in the direction of arrow XXXIIc of FIG. 32 (a). It is a partial side view of the reversing gear 4453.

As shown in FIG. 32, the reversing gear 4453 is an intermediate formed in a region sandwiched between a pair of starting gear teeth 4453b1 arranged adjacent to each other in a pair of arcuate recesses 453c and the starting gear teeth 4453b1. It mainly includes gear teeth 4453b2.

As shown in FIG. 32 (b), the reversing gear 4453 is formed in such a manner that the tooth width of the starting gear tooth 4453b1 is maximized and the tooth width of the intermediate gear tooth 4453b2 is shortened as the distance from the starting gear tooth 4453b1 is increased. .. The degree of shortening (the inclination of the line connecting the upper ends of each gear tooth in FIG. 32 (b)) is the degree of shortening of the tooth width of the dividing gear tooth 4452b of the two-layer gear 4452 (each gear tooth in FIG. 31 (b)). It is formed more gently than the slope of the line connecting the upper ends of.

As shown in FIG. 32 (c), the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 have end faces in the width direction except for the intermediate gear teeth 4453b2 formed farthest from the pair of engaging protrusions 453d. (Upper end surface of FIG. 32B) is formed so as to be inclined downward toward the engaging protrusion receiving portion side. As a result, it is possible to correct the misalignment more rapidly while maintaining a large allowable amount of the relative misalignment in the axial direction at the start of meshing between the reversing gear 4453 and the two-layer gear 4452.

That is, when each gear tooth 4453b1, 4453b2 of the reversing gear 4453 is meshed with the two-layer gear 4452, each gear tooth 4453b1, 4453b2 is on the engaging protrusion receiving portion side (the tooth width is the shortest side, FIG. 32 (c)). From the right side), the teeth start to fit. Therefore, for example, as compared with the case where the dimensions of the gear teeth 4453b1 and 4453b2 in the tooth width direction are constant on the longest tooth width side (left side in FIG. 32C), the plate-shaped portion 4452e at the start of tooth engagement A large distance (play) between the gear teeth 4453b1 and 4453b2 can be secured. Therefore, it is possible to secure a large allowable amount of axial misalignment at the start of meshing between the reversing gear 4453 and the two-layer gear 4452.

On the other hand, when the meshing of the gear teeth 4453b1, 4453b2 of the reversing gear 4453 and the two-layer gear 4452 progresses, the longest tooth width side of each gear tooth 4453b1, 4453b2 (left side in FIG. 32C) is the double-layer gear 4452. It enters the back side (lower side of FIG. 31B) of the plate-shaped portion 4452e. As a result, for example, as compared with the case where the dimensions of the gear teeth 4453b1 and 4453b2 in the tooth width direction are constant on the shortest tooth width side (right side in FIG. (When escaping) The distance (play) between the plate-shaped portion 4452e immediately before and each gear tooth 4453b1 and 4453b2 can be reduced.

Therefore, when the gear teeth 4453b1 and 4453b2 mesh with the two-layer gear 4452, between the plate-shaped portion 4452e and the gear teeth 4453b1, 4453b2 between the start of meshing of each gear tooth 4453b1 and 4453b2 and the disengagement. The interval (play) can be reduced. As a result, the misalignment between the reversing gear 4453 and the two-layer gear 4452 can be corrected more rapidly.

Further, in the present embodiment, the inclination of the plate-shaped portion 4452e (see FIG. 31B) is formed in the opposite direction to the inclination of the gear teeth 4453b1 and 4453b2 of the reversing gear 4453 (see FIG. 32C). It is possible to improve the effect of making the correction of the misalignment more rapidly while maintaining a large allowable amount of the misalignment in the axial direction at the start of meshing between the reversing gear 4453 and the two-layer gear 4452 described above.

The widthwise end surface (upper end surface of FIG. 32B) of the intermediate gear tooth 4453b2 formed farthest from the pair of engaging protrusion receiving portions 453d is formed on a plane perpendicular to the rotation axis of the reversing gear 4453. NS.

Next, the second gear group 5450 according to the fifth embodiment will be described with reference to FIGS. 33 to 35.

In the first embodiment, the case where the two-layer gear 452 is formed of only a single resin material has been described, but in the two-layer gear 5452 according to the fifth embodiment, a magnetic material is embedded inside the starting gear teeth 5452b1. NS. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 33 is a front view of the two-layer gear 5452. As shown in FIG. 33, in the two-layer gear 5452, an embedding hole 5452g is formed in the starting gear tooth 5452b1 along a direction parallel to the rotation axis, and an embedding member 5452h is embedded in the embedding hole 5452g.

The embedding hole 5452g is formed in a bottomed hole shape having a circular cross-sectional diameter, and the embedding member 5452h is formed in a cylindrical shape having a diameter equal to or slightly larger than the diameter of the embedding hole 5452g. As a result, the embedding member 5452h is fitted and fixed in the embedding hole 5452g.

The embedded member 5452h is a cylindrical member formed of a metal magnetic material or a plastic magnetic material, and the south pole and the north pole are divided into two in a plane along the axis. In FIGS. 33 to 35, the black-painted side of the embedded member 5452h is formed by the north pole, and the opposite side is formed by the south pole.

FIG. 34 is a partial front view of the second gear group 5450. Note that FIG. 34 shows a state immediately before the starting gear tooth 5452b1 of the double-layer gear 5452 abuts on the engaging protrusion receiving portion 453d of the reversing gear 5453. Further, the disk portion 452c of the two-layer gear 5452, the gear teeth 452a, and the transmission gear 451 are illustrated by imaginary lines.

As shown in FIG. 34, in the reversing gear 5453, an embedding hole 5453f is formed in the starting gear tooth 5453b1 along a direction parallel to the axis, and an embedding member 5453g is embedded in the embedding hole 5453f. As a result, the embedding member 5453g is fitted and fixed in the embedding hole 5453f.

The embedded member 5453g is a cylindrical member formed of a metal magnetic material or a plastic magnetic material, and the south pole and the north pole are divided into two in a plane along the axis.

As shown in FIG. 34, the plane that divides the magnetic pole into two is formed along the radial direction and is a plane that passes through the axis, and the starting gear teeth 5452b1 and 5453b1 are embedded so that the opposite poles face each other. That is, the starting gear tooth 5452b1 has an N pole formed on the side facing the starting gear tooth 5453b1 at the time of meshing (upper side in FIG. 34), and the starting gear tooth 5453b1 is on the side facing the starting gear tooth 5452b1 at the time of meshing (lower part of FIG. 34). The south pole is formed on the side). As a result, in the meshing of the two-layer gear 5452 and the reversing gear 5453, a magnetic force that attracts the meshing gear teeth 5452b1 and 5453b1 is generated.

That is, as the two-layer gear 5452 is rotated counterclockwise in FIG. 34 from the state shown in FIG. 34, the distance between the embedded members 5452h and 5453g decreases, so that the magnetic force generated between them increases, and the starting gear tooth 5453b1 becomes the starting gear tooth. Attracted to 5452b1. As a result, the reversing gear 5453 is attracted by the magnetic force and rotated before the starting gear teeth 5452b1 of the two-layer gear 5452 and the engaging protrusion receiving portion 453d of the reversing gear 5453 come into contact with each other. Therefore, as compared with the case where the starting gear tooth 5452b1 comes into contact with the stationary reversing gear 5453, the impact at the time of contact and the load received by the two-layer gear 5452 and the reversing gear 5453 at the time of contact can be relaxed.

FIG. 35 is a partial front view of the second gear group 5450. Note that FIG. 35 shows a state in which the two-layer gear 5452 is rotated counterclockwise in FIG. 35 by a predetermined amount from the state shown in FIG. 34. Further, the disk portion 452c of the two-layer gear 5452, the gear teeth 452a, and the transmission gear 451 are illustrated by imaginary lines.

As shown in FIG. 35, a gap is formed between the two-layer gear 5452 and the reversing gear 5453 in front of the two-layer gear 5452 in the rotation direction. As a result, the load applied to the engaging protrusion 453d not only at the start of contact between the two-layer gear 5452 and the reversing gear 5453 but also while the two-layer gear 5452 and the reversing gear 5453 are rotated by the teeth. Can be suppressed. Therefore, the strength required for the engaging protruding receiving portion 453d can be lowered, and the degree of freedom in designing the engaging protruding receiving portion 453d can be improved.

Next, the second gear group 6450 in the sixth embodiment will be described with reference to FIGS. 36 and 37.

In the first embodiment, the case where the two-layer gear 452 is integrally formed has been described, but the two-layer gear 6452 in the sixth embodiment has the starting gear tooth 452b1 omitted and is separate from the intermediate gear tooth 452b2. It is configured to include 6452 g of deformed gear tooth members of the body. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 36 is a front exploded perspective view of the two-layer gear 6452. Note that FIG. 36 shows a state in which the deformed gear tooth member 6452g is removed from the disk portion 452c. In the present embodiment, since the deformed gear tooth member 6452 g is formed of a metal material such as iron, it is compared with a portion of the double-layer gear 6452 other than the deformed gear tooth member 6452 g which is integrally formed of the resin material. Therefore, the rigidity of the deformed gear tooth member 6452 g is increased. Further, by partially using a metal material, the weight can be reduced as compared with the case where the entire two-layer gear 6452 is made of a metal material, and the driving force required to rotate the two-layer gear 6452 can be suppressed. can.

As shown in FIG. 36, the two-layer gear 6452 has a pair of deformed gear tooth members 6452 g and an insertion hole 6452c1 which is a hole through which the deformed gear tooth member 6452 g is inserted and is formed in the disk portion 452c. A notch formed between the first recessed portion 452b3 and the second recessed portion 452b4, the gear tooth side notch 6452b5 in which the gear tooth body portion 6452g1 of the deformed gear tooth member 6452g is sandwiched, and the sliding wall portion 452d. A sliding portion notch 6452d1 in which a sliding receiving portion 6452g3 of a deformed gear tooth member 6452g is sandwiched, and a hook formed in an L-shaped hook shape at both ends of a sliding wall portion 452d. Mainly includes a mold receiving portion 6452d2.

The deformed gear tooth member 6452g includes a gear tooth main body portion 6452g1 having a shape in which the starting gear tooth 452b1 in the first embodiment is extended toward the tooth bottom side, and the gear tooth main body portion 6452g1 from the end opposite to the tooth tip to the back surface. A columnar insertion pin 6452g2 projecting to the side, a sliding receiving portion 6452g3 whose side surface forms a part of the sliding wall portion 452d in the assembled state (see FIG. 37), and a gear tooth body portion 6452g1 sliding. It mainly includes a connecting portion 6452g4 that connects the receiving portion 6452g3.

The gear tooth main body portion 6452g1 is formed so that the tooth thickness of the portion sandwiched by the gear tooth side notch 6452b5 is equal to or slightly larger than the dimension of the gear tooth side notch 6452b5. As a result, the gear tooth main body portion 6452g1 is sandwiched between the gear tooth side notches 6452b5 in the assembled state (see FIG. 37).

The sliding receiving portion 6452g3 is formed in such a manner that the outer peripheral surface is smoothly connected to the outer peripheral surface of the sliding wall portion 452d in the assembled state (see FIG. 37). The outer peripheral surface of the connecting portion 6452g4 is arranged so as to face the recessed bottom wall portion 452e at a slight interval in the assembled state (see FIG. 37).

In the assembled state (see FIG. 37), the insertion pin 6452g2 is inserted into the insertion hole 6452c1 and the gear tooth main body portion 6452g1 is sandwiched between the gear tooth side notches 6452b5. Further, the connecting portion 6452g4 is arranged to face the recessed bottom wall portion 452e of the second recessed portion 452b4 with a slight gap, and the inner peripheral side of the sliding receiving portion 6452g3 is brought into contact with the hook type receiving portion 6452d2. As a result, the gear tooth main body portion 6452g1 is brought into contact with the reversing gear 453, so that the amount of rotation that rotates about the insertion hole 6452c1 can be suppressed.

FIG. 37 is a front view of the two-layer gear 6452 and the reversing gear 453. In FIG. 37, a state in which the gear tooth main body portion 6452g1 of the deformed gear tooth member 6452g is in contact with the engaging protrusion receiving portion 453d of the reversing gear 453 is shown, and the disk portion 452c is shown by an imaginary line. Will be done.

As shown in FIG. 37, the deformed gear tooth member 6452g can receive the load applied from the reversing gear 453 on the engaging protrusion receiving portion 453d of the reversing gear 453.

That is, even if the deformed gear tooth member 6452 g is formed of a metal material, the portion supporting the deformed gear tooth member 6452 g is formed of a resin material. Further, the double-layer gear 6452 is not sufficiently rigid because the thickness in the radial direction is formed to be substantially constant in order to prevent the occurrence of sink marks during molding. Therefore, when the deformed gear tooth member 6452g moves (rotates around the insertion hole 6452c1) due to the load generated when the two-layer gear 6452 and the reversing gear 453 come into contact with each other, the pressing force is applied from the deformed gear tooth member 6452g. There is a risk that parts other than the deformed gear tooth member 6452g (such as the recessed bottom wall portion 452e) will be damaged.

On the other hand, in the present embodiment, the deformed gear tooth member 6452g starts to move in a direction to fill a slight gap formed between the outer peripheral surface of the connecting portion 6452g4 and the recessed bottom wall portion 452e (with the insertion hole 6452c1 as the axis). When it starts to rotate), the sliding receiving portion 6452g3 of the deformed gear tooth member 6452g is pressed against the arcuate concave portion 453c of the reversing gear 453. The arcuate recess 453c is a portion having a sufficient radial thickness and high rigidity.

As a result, the deformed gear tooth member 6452g can receive the load applied from the reversing gear 453 to the engaging protrusion receiving portion 453d of the reversing gear 453, which is a portion of the double-layer gear 6452 other than the deformed gear tooth member 6452g. The load applied to the portion (recessed bottom wall portion 452e, etc.) can be suppressed. Further, the arcuate recess 453c of the reversing gear 453 can be used to support the deformed gear tooth member 6452g.

Next, the combined operation unit 7400 according to the seventh embodiment will be described with reference to FIGS. 38 to 45.

In the first embodiment, the case where the position of the slide member 420 when the half-moon member 460 rotates is limited to one way, but the combined operation unit 7400 in the seventh embodiment describes the case where the half-moon member 460 rotates. At least two positions of the slide member 420 can be formed. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

38 (a) to 38 (c) are rear views of the two-layer gear 7452. Note that FIG. 38 (a) shows a stationary state in which the rotation of the double-layer gear 7452 is stopped, and FIG. 38 (b) shows the first rotation in which the rotation speed V of the double-layer gear 7452 is lower than the boundary speed Vb. The state of the speed V1 is illustrated, and in FIG. 38 (c), the state in which the rotation speed V of the two-layer gear 7452 is the second rotation speed V2 higher than the boundary speed Vb is shown.

For ease of understanding, the gear teeth 452a and the disk portion 452c are not shown. This also applies to the subsequent drawings. Further, the boundary speed Vb means the rotational speed V of the double-layer gear 7452 when the protruding gear member 7452e is switched from the immersed state to the extended state.

As shown in FIG. 38, the two-layer gear 7452 is formed with a guide groove 7452d, which is a groove having a rectangular cross section formed from the rotation axis toward the outside in the radial direction, and a width slightly smaller than the groove width of the guide groove 7452d. It is mainly composed of a protruding gear member 7452e whose tip is formed in a gear tooth shape, and an urging spring 7452f that connects the protruding gear member 7452e and the rotating shaft of the two-layer gear 7452.

The guide groove 7452d is formed at three locations so as to divide the outer circumference of the two-layer gear 7452 into three equal parts in the circumferential direction, and the protruding gear member 7452e and the urging spring 7452f are arranged in each guide groove 7452d. Further, intermediate gear teeth 452b2 are formed on the outer peripheral surface of the two-layer gear 7452 connecting the guide grooves 7452d.

In the protruding gear member 7452e, each protruding gear member 7452e1 to 7452e3 is formed with the same mass, and each urging spring 7452f is formed with the same spring constant.

As shown in FIG. 38 (a), in the stopped state of the two-layer gear 7452, the protruding gear member 7452e is immersed in the rotation shaft side of the surface of the intermediate gear teeth 452b2 in which the tooth bottoms are connected. At this time, the illegal spring 7452f has a natural length.

As shown in FIG. 38 (b), when the two-layer gear 7452 is rotated at the first rotation speed V1 which is lower than the boundary speed Vb, the protruding gear member 7452e is moved outward in the radial direction of the two-layer gear 7452. Power is generated. The protruding gear member 7452e is extended to a position where this force and the urging force of the urging spring 7452f are balanced. In the overhanging state, the protruding gear member 7452e is positioned on the rotation axis side of the surface of the intermediate gear teeth 452b2 in which the tooth tips are connected (immersive state).

Therefore, as will be described later, when the two-layer gear 7452 is rotated at the first rotation speed V1, the two-layer gear 7452 does not start meshing with the reversing gear 7453 (see FIG. 42). That is, the two-layer gear 7452 runs idle with respect to the reversing gear 7453.

As shown in FIG. 38 (c), when the double-layer gear 7452 is rotated at a second rotation speed V2 higher than the boundary speed Vb, the protruding gear member 7452e is moved outward in the radial direction of the double-layer gear 7452. Power is generated. The protruding gear member 7452e is extended to a position where this force and the urging force of the urging spring 7452f are balanced. In the overhanging state, the protruding gear member 7452e projects radially outward from the surface of the intermediate gear teeth 452b2 in which the tooth tips are connected (overhanging state).

Therefore, as will be described later, when the two-layer gear 7452 is rotated at the second rotation speed V2, the protruding gear member 7452e of the two-layer gear 7452 abuts on the reversing gear 7453 (see FIG. 39). The layer gear 7452 begins to mesh with the reversing gear 7453.

That is, whether or not the two-layer gear 7452 starts to mesh with the reversing gear 7453 (see FIG. 39) depending on whether the rotation speed V of the two-layer gear 7452 is higher or lower than the boundary speed Vb. You can choose. Therefore, by changing the rotation speed V of the double-layer gear 7452 in the middle of rotation (by changing the moving speed of the slide member 420 (see FIG. 40) in the middle of movement), the half-moon member 460 (see FIG. 40). It is possible to prepare a plurality of variations in the arrangement of the slide member 420 when the slide member 420 is rotated.

Next, with reference to FIGS. 39 to 44, variations in the arrangement of the slide member 420 when the half moon member 460 starts to rotate will be described. First, a case where the main gear 7452 is rotated at the second rotation speed V2 immediately after the start of movement of the moving member 420 from the retracted position (first speed pattern) will be described with reference to FIGS. 39 to 41.

39 (a) to 39 (e) are rear views of the two-layer gear 7452 and the reversing gear 7453 in which the rotations of the two-layer gear 7452 and the reversing gear 7453 are illustrated in chronological order. 40 (b), FIGS. 41 (a) and 41 (b) are front views of the combined operation unit 7400 showing the slide movement of the slide member 420 and the posture change of the half moon member 460 in chronological order. For ease of understanding, the gear teeth 452a and the disc portion 452c are omitted in FIG. 39, and the fastening plate portion 471 and the drive motor 472 are omitted in FIGS. 40 and 41.

39 (a) and 40 (a), 39 (b) and 40 (b), 39 (c) and 41 (a), and 39 (d) and 41 (b). Are diagrams of substantially simultaneous points, and they correspond to each other. Further, in FIG. 39, the rotation direction of the two-layer gear 7452 is illustrated by an arrow, and as shown in FIG. 39, the arcuate recess 453c is circumscribed by a circle connecting the tooth tips of the intermediate gear teeth 452b2 of the two-layer gear 7452. It is formed in such a manner.

As shown in FIG. 39 (a), the two-layer gear 7452 is rotated at the second rotation speed V2 immediately after the start of movement of the slide member 420 (see FIG. 40 (a)), and the two-layer gear 7452 is rotated by a predetermined amount. And the first protruding gear member 7452e1 are brought into contact with the engaging protrusion receiving portion 453d of the reversing gear 7453 (see FIG. 39B). As a result, the reversing gear 7453 begins to rotate, and the half-moon member 460 begins to change its posture (see FIG. 40 (b)).

After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other to continue the rotation of the reversing gear 7453 and change the posture of the half moon member 460. Is continued (see FIGS. 39 (c) and 41 (a)).

After the intermediate gear teeth 452b2 of the double-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, the double-layer gear 7452 is further rotated, so that the arcuate recess 453c of the reversing gear 7453 is re-engaged with the double-layer gear 7452. (See FIG. 39 (d)), the rotation of the reversing gear 7453 is stopped, and the posture of the half-moon member 460 with respect to the slide member 420 is fixed (see FIG. 41 (b)).

After that, the two-layer gear 7452 is rotated until the slide member 420 finishes sliding (see FIG. 26 (b)), and the rotation is stopped when the slide member 420 is stopped (see FIG. 39 (e)). After that, the protruding gear member 7452e is moved inward in the radial direction of the two-layer gear 7452 by the urging force of the urging spring 7452f.

Here, when the two-layer gear 7452 is rotated from the state of FIGS. 39 (d) to 39 (e), the third protruding member 7452e3 and the first protruding member 7452e1 hit the engaging projecting receiving portion 453d. There is a risk that the two-layer gear 7452 and the reversing gear 7453 will come into contact with each other and mesh again.

On the other hand, in the present embodiment, an arc-shaped chamfered portion 7453e is formed at one end (the upper end in FIG. 39E) of the engaging protrusion receiving portion 453d.

When the third protruding member 7452e3 and the first protruding member 7452e1 are brought into contact with the chamfered portion 7453e, a force acting inward in the radial direction of the two-layer gear 7452 is applied to the third protruding member 7452e3 and the first protruding member 7452e1. As a result, the third protruding member 7452e3 and the first protruding member 7452e1 can be immersed in the third protruding member 7452e3 and the first protruding member 7452e1 before they mesh with the reversing gear 745. Therefore, it is possible to prevent the two-layer gear 7452 and the reversing gear 7453 from meshing again.

Next, referring to FIGS. 42 to 44, immediately after the start of movement of the moving member 420 from the retracted position, the two-layer gear 7452 is rotated at the first rotation speed V1, and the two-layer gear 7452 is second-rotated during the rotation. The case where the rotation speed V2 is rotated (the rotation speed V is changed) (second speed pattern) will be described.

42 (a) to 42 (e) are rear views of the two-layer gear 7452 and the reversing gear 7453 in which the rotations of the two-layer gear 7452 and the reversing gear 7453 are illustrated in chronological order. 43 (b), FIG. 44 (a) and FIG. 44 (b) are front views of the combined operation unit 7400 showing the slide movement of the slide member 420 and the posture change of the half moon member 460 in chronological order. For ease of understanding, the gear teeth 452a and the disc portion 452c are omitted in FIG. 42, and the fastening plate portion 471 and the drive motor 472 are omitted in FIGS. 43 and 44.

It should be noted that FIG. 42 (a) and the above-mentioned FIGS. 40 (a), 42 (b) and 43 (a), 42 (c) and 43 (b), 42 (d) and 44 (a). ), And FIGS. 42 (e) and 44 (b) are diagrams of substantially simultaneous points, and are in a corresponding relationship with each other. Further, in FIG. 42, the rotation direction of the two-layer gear 7452 is illustrated by an arrow, and as shown in FIG. 42 (a), the arcuate recess 453c is a circle in which the tooth tips of the intermediate gear teeth 452b2 of the two-layer gear 7452 are connected. It is formed in a manner circumscribing to.

As shown in FIG. 42 (a), the two-layer gear 7452 is rotated at the first rotation speed V1 immediately after the start of movement of the slide member 420 (see FIG. 40 (a)), so that the protruding gear member 7452e is immersed. Form.

Therefore, even if the two-layer gear 7452 is rotated by a predetermined amount, the first protruding gear member 7452e1 is not brought into contact with the engaging protrusion receiving portion 453d of the reversing gear 7453, so that the mesh between the two-layer gear 7452 and the reversing gear 7453 is not good. Not started (see FIG. 42 (b)). As a result, the slide member 420 is moved while maintaining the posture of the half-moon member 460 (see FIG. 43 (a)).

The rotation speed V of the two-layer gear 7452 is changed to the second rotation speed V2 until the two-layer gear 7452 continues to rotate and the second protruding gear member 7452e2 approaches the engaging protrusion receiving portion 453d of the reversing gear 7453. Will be done. As a result, the protruding gear member 7452e forms an overhanging state (see FIG. 42C), and the second protruding gear member 7452e2 is brought into contact with the engaging projecting receiving portion 453d to rotate the reversing gear 7453. At the same time, the half-moon member 460 begins to change its posture (see FIG. 43 (b)).

After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other to continue the rotation of the reversing gear 7453 and change the posture of the half moon member 460. Is continued (see FIGS. 42 (d) and 44 (a)).

After the intermediate gear teeth 452b2 of the double-layer gear 7452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, the double-layer gear 7452 is further rotated, so that the arcuate recess 453c of the reversing gear 7453 is re-engaged with the double-layer gear 7452. (See FIG. 42 (e)), the rotation of the reversing gear 7453 is stopped, and the posture of the crescent member 460 with respect to the slide member 420 is fixed (see FIG. 44 (b)).

After that, the two-layer gear 7452 is rotated until the slide member 420 finishes sliding (see FIG. 26B), and the slide member 420 is stopped to stop the rotation.

Since the rotation speed V of the two-layer gear 7452 and the moving speed of the slide member 420 are in a proportional relationship, it is easy to change the rotation speed V of the two-layer gear 7452 by changing the rotation speed of the drive motor 472. Can be done.

As described above, according to the present embodiment, the position of the slide member 420 is changed in at least two ways when the half moon member 460 starts to rotate while the slide member 420 is slid from the retracted position to the overhanging position. be able to. That is, as compared with the case where the two-layer gear 7452 is rotated at the second rotation speed V2 from the start of rotation (see FIGS. 39 to 41), the first rotation speed V1 is changed to the second rotation speed V2 during the rotation. When changed (see FIGS. 42 to 44), the arrangement of the slide member 420 when the half moon member 460 rotates can be moved toward the center side (center side in the vertical direction) (FIGS. 40 (b) and FIG. 43 (b)). This makes it possible to increase the variation of the production.

Next, with reference to FIG. 45, typical examples of the first speed pattern and the second speed pattern described above will be described. FIG. 45 is a graph showing the speed change of the two-layer gear 7452. In FIG. 45, the horizontal axis indicates the position (P) of the slide member 420 between the retracted position (P = 0) and the overhanging position (P = Pmax), and the vertical axis represents the slide of the slide member 420. The rotation speed V of the two-layer gear 7452 that is rotated during movement is shown.

In the horizontal axis of FIG. 45, the first position P1 means the position where the first protruding gear member 7452e1 is first arranged to face the reversing gear 7453 (see FIG. 39B), and the second position P2 is , The position where the second protruding gear member 7452e2 is first arranged to face the reversing gear 7453 (FIG. 42 (c). The solid line shows the above-mentioned first speed pattern, and the broken line shows the above-mentioned second speed pattern. Shown.

As described above, in the present embodiment, when the two-layer gear 7452 is rotated in the first speed pattern, the half-moon member 460 starts to change its posture immediately after the slide member 420 reaches the first position P1. On the other hand, when the two-layer gear 7452 is rotated in the second speed pattern, the half-moon member 460 begins to change its posture immediately after the slide member 420 reaches the second position P2.

That is, by changing the rotation speed V of the two-layer gear 7452 during the slide movement of the slide member 420, the position of the slide member 420 when the posture of the half-moon member 460 begins to change can be changed. Therefore, it is possible to increase the variation of the effect of the slide member 420 and the half moon member 460.

Next, the combined operation unit 8400 according to the eighth embodiment will be described with reference to FIGS. 46 to 48.

In the seventh embodiment, the case where the position of the slide member 420 when the half moon member 460 rotates is changed by changing the rotation speed V of the two-layer gear 7452 in the middle of rotation has been described. The composite operation unit 8400 is formed so that the position of the slide member 420 when the half moon member 460 rotates can be changed while the rotation speed of the two-layer gear 8452 is maintained at a constant speed. The same parts as those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

46 (a) and 46 (b) are rear views of the two-layer gear 8452. Note that FIG. 46 (a) shows a state in which the double-layer gear 8452 is rotated at a separate rotation speed V3, and FIG. 46 (b) shows a state in which the double-layer gear 8452 is rotated at a joint rotation speed V4. Will be done. Since the stationary state in which the rotation of the two-layer gear 8452 is stopped is the same as in FIG. 38 (a), the description thereof will be omitted.

For ease of understanding, the gear teeth 452a and the disk portion 452c are not shown. This also applies to the subsequent drawings. Further, the separated rotation speed V3 means a rotation speed at which the first protruding gear member 7452e1 forms an immersive state while the second protruding gear member 7452e2 forms an overhanging state, and the joint rotation speed V4 is the first. 1 It means the rotation speed at which the protruding gear member 7452e1 and the second protruding gear member 7452e2 both form an overhanging state.

As shown in FIG. 46 (a), when the two-layer gear 8452 is rotated at the separated rotation speed V3, each protruding gear member 7452e is moved outward in the radial direction of the two-layer gear 8452 with a different overhang amount. (At least the second protruding gear member 7452e2 has a larger amount of movement than the first protruding gear member 7452e1).

In the present embodiment, the spring constants of the urging springs 8452f that connect the protruding gear members 7452e and the rotating shafts of the two-layer gears 7452 are formed differently. That is, the spring constant of the first urging spring 8452f1 that connects the first protruding gear member 7452e1 and the rotating shaft of the two-layer gear 8452 is the second that connects the second protruding gear member 7452e2 and the rotating shaft of the two-layer gear 8452. 2 It is made larger than the spring constant of the urging spring 8452f2. The spring constant of the third urging spring 8452f3 is made larger than the spring constant of the first urging spring 8452f1.

As shown in FIG. 46 (a), when the two-layer gear 7452 is rotated at the separated rotation speed V3, the first protruding gear member 7452e1 is positioned on the rotation axis side of the surface of the intermediate gear teeth 452b2 in which the tooth tips are connected. (Immersion state), the second protruding gear member 7452e2 projects radially outward from the surface of the intermediate gear teeth 452b2 in which the tooth tips are connected (overhanging state).

Therefore, as will be described later, when the two-layer gear 8452 is rotated at the separated rotation speed V3, the two-layer gear 8452 does not start meshing with the reversing gear 7453 in the first protruding gear member 7452e1, and the second protruding gear The member 7452e2 meshes with the reversing gear 7453.

As shown in FIG. 46 (b), when the two-layer gear 8452 is rotated at the joint rotation speed V4, a force is generated to move the protruding gear member 7452e to the outside in the radial direction of the two-layer gear 8452. The protruding gear member 7452e is extended to a position where this force and the urging force of the urging spring 8452f are balanced. In the overhanging state, at least the first protruding gear member 7452e1 and the second protruding gear member 7452e2 project radially outward from the surface of the intermediate gear teeth 452b2 in which the tooth tips are connected (overhanging state).

Therefore, when the double-layer gear 8452 is rotated at the joint rotation speed V4, the first protruding gear member 7452e1 of the protruding gear member 7452e of the double-layer gear 8452 abuts on the reversing gear 7453, so that the double-layer gear 7452 Begins to be meshed with the reversing gear 7453.

Since the operations of the two-layer gear 8452, the reversing gear 7453, and the slide member 420 when the two-layer gear 8452 is rotated at a constant speed of the joint rotation speed V4 are the same as the operations shown in FIGS. 39 to 41. The explanation is omitted.

47 (a) to 47 (e) are rear views of the two-layer gear 8452 and the reversing gear 7453 showing the rotations of the two-layer gear 8452 and the reversing gear 7453 in chronological order. In the description of FIG. 47, FIGS. 40, 43 and 44 are appropriately referred to, and in FIG. 47, the gear teeth 452a and the disk portion 452c are omitted for easy understanding.

It should be noted that FIG. 47 (a) and the above-mentioned FIGS. 40 (a), 47 (b) and 43 (a), 47 (c) and 43 (b), 47 (d) and 44 (a). ), And FIGS. 47 (e) and 44 (b) are diagrams of substantially simultaneous points, and are in a corresponding relationship with each other. Further, in FIG. 47, the rotation directions of the two-layer gear 8452 and the reversing gear 7453 are illustrated by arrows, and as shown in FIG. 47, the arcuate recess 453c connects the tooth tips of the intermediate gear teeth 452b2 of the two-layer gear 8452. It is formed in a manner circumscribing a circle.

As shown in FIG. 47 (a), since the two-layer gear 8452 is rotated at the separation rotation speed V3 immediately after the start of movement of the slide member 420 (see FIG. 40 (a)), the first protruding gear member 7452e1 is in an immersive state. The second protruding gear member 7452e2 forms an overhanging state.

Therefore, even if the two-layer gear 8452 is rotated by a predetermined amount, the first protruding gear member 7452e1 is not brought into contact with the engaging protrusion receiving portion 453d of the reversing gear 7453, so that the mesh between the two-layer gear 8452 and the reversing gear 7453 is not good. It does not start (see FIG. 47 (b)). As a result, the slide member 420 is moved while maintaining the posture of the half-moon member 460 (see FIG. 43 (a)).

The two-layer gear 8452 continues to rotate at the separated rotation speed V3, and the second protruding gear member 7452e2 is brought into contact with the engaging projectile receiving portion 453d, so that the reversing gear 7453 starts to rotate and the half moon member 460 is in a posture. It begins to change (see FIG. 43 (b)).

After the reversing gear 7453 starts to rotate, the intermediate gear teeth 452b2 of the double-layer gear 8452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other to continue the rotation of the reversing gear 7453 and change the posture of the half moon member 460. Is continued (see FIGS. 47 (d) and 44 (a)).

After the intermediate gear teeth 452b2 of the double-layer gear 8452 and the intermediate gear teeth 453b2 of the reversing gear 7453 mesh with each other, the double-layer gear 8452 is further rotated, so that the arcuate recess 453c of the reversing gear 7453 is re-engaged with the double-layer gear 8452. (See FIG. 47 (e)), the rotation of the reversing gear 7453 is stopped, and the posture of the half moon member 460 is fixed (see FIG. 44 (b)).

After that, the two-layer gear 8452 is rotated until the slide member 420 finishes sliding (see FIG. 26B), and the slide member 420 is stopped to stop the rotation.

As described above, according to the present embodiment, the position of the slide member 420 is changed in at least two ways when the half moon member 460 starts to rotate while the slide member 420 is slid from the retracted position to the overhanging position. Therefore, the speed change during the slide movement of the slide member 420 is not required.

That is, compared to the case where the two-layer gear 8452 is rotated at a constant speed at the joint rotation speed V4 (see FIGS. 40 and 41), the case where the two-layer gear 8452 is rotated at a constant speed at a separate rotation speed V3 (FIG. 43). And FIG. 44), the arrangement of the slide member 420 when the half-moon member 460 is rotated can be moved toward the center side (center side in the vertical direction) (see FIGS. 40 (b) and 43 (b)). This makes it possible to increase the variation of the production.

Next, with reference to FIG. 48, the above-mentioned separated rotation speed V3 and joint rotation speed V4 will be described as a graph. FIG. 48 is a graph showing the rotation speed V of the two-layer gear 7452. In FIG. 48, the horizontal axis indicates the position (P) of the slide member 420 between the retracted position (P = 0) and the overhanging position (P = Pmax), and the vertical axis indicates the slide member 420. The rotation speed V of the two-layer gear 7452 that is rotated when the slide is moved is shown.

On the horizontal axis of FIG. 48, the first position P1 means the position where the first protruding gear member 7452e1 is first arranged to face the reversing gear 7453 (see FIG. 39B), and the second position P2 is , The position where the second protruding gear member 7452e2 is first arranged to face the reversing gear 7453 (meaning FIG. 42C).

As described above, in the present embodiment, when the two-layer gear 7452 is rotated at the joint rotation speed V4, the half-moon member 460 begins to change its posture immediately after the slide member 420 reaches the first position P1. On the other hand, when the two-layer gear 7452 is rotated at the separation rotation speed V3, the half-moon member 460 begins to change its posture immediately after the slide member 420 reaches the second position P2.

That is, if two types of slide movement speeds of the slide member 420 are set, the slide member 420 when the posture of the half moon member 460 starts to change without changing the slide movement speed of the slide member 420 during movement. The position of can be changed. Therefore, it is possible to increase the variation of the effect of the slide member 420 and the half moon member 460.

Although the present invention has been described above based on the above-described embodiment, the present invention is not limited to the above-described embodiment, and it is easy to make various modifications and improvements within a range that does not deviate from the gist of the present invention. It can be inferred.

In each of the above embodiments, a part or all of the configurations in one embodiment may be combined with or replaced with a part or all of the configurations in another embodiment to form another embodiment.

In each of the above embodiments, the case where the claw member 463 of the half-moon member 460 moves due to the movement of the slide rack 442 has been described, but the present invention is not necessarily limited to this. For example, a locking pin is arranged in a rotation locus in which the drive lever 467 is rotated by rotating the half moon member 460, and the drive lever 467 is dammed by the locking pin to form the half moon member 460 and the drive lever. A rotation angle difference may occur between the two, and the claw member 463 may be moved. In this case, the rotation of the half-moon member 460 and the movement of the claw member 463 can be linked.

In each of the above embodiments, the case where the cutout portion 422d of the slide member 420 is formed in an arc shape has been described, but the present invention is not necessarily limited to this. For example, it may be cut out in a rectangular shape in a direction away from the drive gear 473. As a result, the degree of freedom in designing the notch portion 422d can be improved, and the material required for the slide member 420 can be reduced.

In each of the above embodiments, the case where the shape in which the tooth tips of the drive gear 473 are connected is substantially circular has been described, but the present invention is not necessarily limited to this. For example, the drive gear 473 may be divided into four in the circumferential direction, and the tooth depth of the gear teeth may be different for each of the divided parts. In this case, by attaching the drive gear 473 toward the transmitted leg portion 422 with the portion of the gear tooth having a short tooth gap, the size required for the notch portion 422d of the transmitted leg portion 422 to pass the drive gear 473 is increased. Can be reduced. On the other hand, it is possible to secure the transmission of the driving force to the transmitted leg portion 422 at the portion where the gear teeth have a long tooth gap. In addition, in the above-mentioned divided portion, there may be a portion where gear teeth are not formed.

In each of the above embodiments, the case where the drive gear 473 is attached / detached through the notch portions 422d formed in the pair of transmitted leg portions 422 arranged to face each other has been described, but the present invention is not necessarily limited to this. For example, the cutout portion 422d may not be formed in the transmitted leg portion 422, and the transmitted leg portion 422 may be formed so as to be movable in a direction away from each other (a direction perpendicular to the slide direction). In this case, the drive gear 473 cannot be removed when the pair of transmitted legs 422 are arranged close to each other, while the drive gear 473 is removable when the pair of transmitted legs 422 are arranged at a distance. can do.

In the fifth embodiment, the case where the embedding member 5452h formed of the magnetic material is embedded in the embedding hole 5452g of the two-layer gear 5452 has been described, but the present invention is not necessarily limited to this. For example, the periphery of the starting gear teeth 5452b1 of the two-layer gear 5452 may be covered with a magnetic material. As a result, the magnetic material can be arranged outside the starting gear tooth 5452b1, so that the distance between the reversing gear 5453 and the magnetic material can be shortened, and the two-layer gear 5452 and the reversing gear 5453 act at the start of meshing. The magnetic force can be made stronger.

In the fifth embodiment, the case where the embedded hole 5453f is formed in the starting gear tooth 5453b1 of the reversing gear 5453 has been described, but the present invention is not necessarily limited to this. For example, the embedding hole 5453f may be formed in a manner in which the engaging projecting receiving portion 453d is bored and the embedding member 5453g is embedded. In this case, the embedded members 5452h and 5453g are embedded so that the magnetic force of the embedded member 5453g and the magnetic force of the embedded member 5452h embedded in the two-layer gear 5452 repel each other, thereby reversing with the two-layer gear 5452. The impact at the time of contact of the gear 5453 can be alleviated. That is, before the starting gear tooth 5452b1 of the double-layer gear 5452 is brought into contact with the engaging projectile receiving portion 453d of the reversing gear 5453, the reversing gear 5453 is rotated in a direction away from the starting gear tooth 5452b1 by the repulsive magnetic force. Can be done. Therefore, the durability of the starting gear tooth 5452b1 can be improved.

In the seventh embodiment, the case where the masses of the protruding gear members 7452e are equal has been described, but the present invention is not necessarily limited to this. For example, each protruding gear member 7452e may be formed with a different mass, and the spring constant of the urging spring 7452f for urging the protruding gear member 7452e having a larger mass may be formed to be larger. Thereby, the difference in the way of projecting the protruding gear member 7452e depending on the magnitude of the mass can be alleviated by the magnitude of the urging force of the urging spring 7452f.

In the seventh and eighth embodiments, the protruding gear member 7452e of the two-layer gears 7452 and 8452 is movably formed so that the timing of contact between the two-layer gears 7452 and 8452 and the reversing gear 7453 can be changed. However, this is not always the case. For example, the reversing gear 7453 may be formed so as to be movable in the direction perpendicular to the axis of the two-layer gears 7452 and 8452. In this case, the reversing gear 7453 can be separated from the two-layer gears 7452, 8452 to form a state in which they are not in contact with each other, while the reversing gear 7453 can be brought into contact with the two-layer gears 7452, 8452. Can be. Therefore, even when the movable protruding gear member 7452e is not required, the timing of contact between the two-layer gears 7452 and 8452 and the reversing gear 7453 can be changed.

In the seventh and eighth embodiments, the protruding gear member 7452e of the two-layer gears 7452 and 8452 is movably formed so that the timing of contact between the two-layer gears 7452 and 8452 and the reversing gear 7453 can be changed. However, this is not always the case. For example, the two-layer gears 7452 and 8452 may be able to form a first state in which the reversing gear 7453 and the transmission gear 451 are not meshed with each other and a second state in which the reversing gear 7453 and the transmission gear 451 are meshed with each other. In this case, the driving force is not transmitted to the two-layer gears 7452 and 8452 in the first state, while the driving force can be transmitted to the two-layer gears 7452 and 8452 in the second state. Therefore, even when the movable protruding gear member 7452e is not required, the timing at which the reversing gear 7453 starts operating can be changed.

In the eighth embodiment, the case where the masses of the protruding gear members 7452e are equal and the spring constants of the urging springs 8452f are different has been described, but the present invention is not necessarily limited to this. For example, the spring constants of the urging springs 8452f may be the same, and the masses of the protruding gear members 7452e may be different. Thereby, the overhang amount of each protruding gear member 7452e can be adjusted more easily than adjusting the spring constant.

In each of the above embodiments, the case where the drive gear 473 is pivotally supported by the drive shaft of the drive motor 472 at one point has been described, but the present invention is not necessarily limited to this. For example, a plurality of pins are projected from the end portions of the shaft support members fixed to the drive shaft of the drive motor 472, and a plurality of fitting portions into which the plurality of pins are fitted are formed in the rotating body portion of the drive gear 473. The shaft support member and the drive gear 473 may be engaged with each other at a plurality of points. In this case, the phase relationship between the drive shaft of the drive motor 472 and the drive gear 473 can be maintained by the pins being caught by the drive gear 473 in the rotational direction, so that the drive gear 473 and the plurality of pins are loosely fitted. can do.

As a result, the force required to separate the drive motor 472 and the rotating body portion of the drive gear 473 can be reduced, so that the front side wall portion 422c of the transmitted leg portion 422 is deformed or excessive stress is applied to the drive motor 472. It is possible to prevent it from being added.

The present invention may be implemented in a pachinko machine or the like of a type different from each of the above embodiments. For example, once a jackpot is hit, a pachinko machine (commonly known as a two-time right item, a three-time right item) that raises the expected value of the jackpot until multiple times (for example, two or three times) a big hit state occurs. It may be carried out as). Further, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that generates a special game that gives a player a predetermined game value on the condition that a ball is won in a predetermined area. Further, it may be carried out on a pachinko machine that has a winning device having a special area such as a V zone and is in a special gaming state on the condition that a ball is won in the special area. Further, in addition to the pachinko machine, it may be implemented as various game machines such as a pachinko machine, a sparrow ball, a slot machine, a so-called pachinko machine and a slot machine.

In the slot machine, for example, the symbol is changed by operating the operation lever in a state where a coin is inserted to determine the symbol effective line, and the symbol is stopped and confirmed by operating the stop button. It is a thing. Therefore, the basic concept of the slot machine is "provided with a display device for variably displaying an identification information string composed of a plurality of identification information and then confirming and displaying the identification information, which is caused by the operation of a starting operation means (for example, an operation lever). The variable display of the identification information is started, and the variable display of the identification information is stopped and confirmed and displayed due to the operation of the stop operation means (for example, the stop button) or after a predetermined time has elapsed, and the stop is stopped. It becomes a "slot machine that generates a special game that gives a player a predetermined game value on the condition that the combination of time identification information is specific". In this case, the game medium is represented by coins, medals, etc. Take as an example.

Further, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a display device for variably displaying a symbol sequence composed of a plurality of symbols and then confirming the symbol is provided, and a handle for launching a ball is provided. Some are not. In this case, after a predetermined amount of balls are thrown in based on a predetermined operation (button operation), the symbol variation is started, for example, due to the operation of the operation lever, and for example, due to the operation of the stop button or a predetermined amount. As time elapses, the fluctuation of the symbol is stopped, and a special game is generated that gives the player a predetermined game value on the condition that the confirmed symbol at the time of the stop is a so-called jackpot symbol, and the player is given a predetermined game value. Is for paying out a large amount of balls to the lower saucer. If such a game machine is used instead of a slot machine, only the ball can be treated as a game value in the game hall, which is a game value seen in the current game hall where pachinko machines and slot machines are mixed. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the locations where game machines are installed can be solved.

The concepts of various inventions included in the above-described embodiments in addition to the gaming machine of the present invention are shown below.

<Example of technical concept in which the drive gear 473 and the notch 422d overlap>
A first gear member and a second gear member that are supported by a base member and have gear teeth engraved on the side surfaces and are meshed with each other are provided, and at least the first gear member is formed from a rotary gear and the second gear member. Is provided with a plate-shaped portion that is overlaid on the side surface of the gear tooth, and the plate-shaped portion is the gear tooth of the first gear member in the direction of rotation axis of the first gear member, and the second gear member. A gaming machine that is formed so as to be able to overlap the gear teeth that are in mesh with the gear member, and the plate-shaped portion is scooped out from the tooth tip side to the tooth bottom side of the gear teeth of the second gear member. The notch portion to be formed is provided, and the notch portion and the first gear member are arranged at predetermined positions, so that at least the first gear member and the plate-shaped portion rotate the first gear member. A game machine A1 characterized in that it is possible to form a specific phase position that is visually recognized at intervals in an axial view.

Here, in a gaming machine such as a pachinko machine, a plate-shaped portion is formed on the side surface of the gear teeth of one of the pair of gear members to be meshed with each other, so that the inside of the pair of gear members There is a gaming machine that prevents the other gear member, which is the gear member on the opposite side of one gear member, from moving in the axial direction (see, for example, Japanese Patent Application Laid-Open No. 2012-217702). However, in the above-mentioned conventional gaming machine, when the other gear member is pulled out, it is necessary to pull out one gear member in advance. Therefore, there is a problem that maintainability is low.

On the other hand, according to the gaming machine A1, the notch is formed in the plate-shaped portion, so that the plate-shaped portion and the first gear member are formed at least at a specific phase position in the direction of the rotation axis of the first gear member. It is visually recognized at intervals. Therefore, at the specific phase position, the first gear member can be pulled out through the notch portion of the plate-shaped portion, so that the first gear member can be replaced without pulling out the second gear member in advance. Therefore, it is possible to improve the maintainability of the pair of gear members to be meshed with each other.

Since the first gear member is formed of a rotary gear, the second gear member on which the plate-shaped portion is formed may be a rotary gear or a rack gear.

In the game machine A1, the notch portion has a forming width on the tooth tip side of the second gear member along the continuous direction of the gear teeth of the second gear member, and the tooth tip of the second gear member. The distance between the point where the outer shape of the first gear member and the tooth tip circle of the first gear member intersect with each other is set to be equal to or slightly larger than the distance along the continuous direction of the gear teeth of the second gear member. Game machine A2.

According to the gaming machine A2, in addition to the effect of the gaming machine A1, the period in which the first gear member overlaps the notch portion in the direction of rotation axis of the first gear member can be shortened to the minimum. Thereby, the action of restricting the movement of the first gear member in the rotation axis direction can be ensured by the plate-shaped portion.

The shape of the notch is not particularly limited, and may be an arc shape or a rectangular shape.

Further, the size of the gear teeth of the second gear member does not have to be uniform. For example, when the second gear member is divided into four in the circumferential direction and the size of the gear teeth (particularly the tooth depth) is different for each divided portion, the tip circle of the small gear teeth and the second gear are formed. By forming the notch at the distance between the points where the outer shape of the tooth tips of the member intersects, the notch is formed as compared with the case where the notch is formed based on the tooth tip circle of the large gear tooth. It is possible to prevent the portion from becoming large. Therefore, the action of restricting the movement of the first gear member in the direction of the rotation axis can be ensured by the plate-shaped portion. In addition, in the above-mentioned divided portion, there may be a portion where gear teeth are not formed.

In the gaming machines A1 or A2, the notch is a circle formed coaxially with the first gear member and having a diameter slightly larger than the tooth tip circle of the first gear member. 1 A gaming machine A3 characterized in that it is formed in an overlapping shape when projected onto the plate-shaped portion from the direction of the rotation axis of the gear member.

According to the gaming machine A3, in addition to the effect of the gaming machine A1 or A2, the notch portion is formed to have a diameter slightly larger than the tooth tip circle of the first gear member, and a circle coaxial with the first gear member is formed. 1 It is formed in an overlapping shape when projected onto a plate-shaped portion from the direction of the rotation axis of the gear member. Therefore, the size of the notch portion can be minimized, the formation area of the plate-shaped portion can be secured to the maximum, and the rigidity of the plate-shaped portion can be improved.

The size of the gear teeth of the second gear member does not have to be uniform. For example, when the second gear member is divided into four in the circumferential direction and the size of the gear teeth (particularly the tooth depth) is different for each divided portion, the tip circle of the small gear teeth and the second gear are formed. By forming the notch at the distance between the points where the outer shape of the tooth tips of the member intersects, the notch is formed as compared with the case where the notch is formed based on the tooth tip circle of the large gear tooth. It is possible to prevent the portion from becoming large. Therefore, the formed area of the plate-shaped portion can be secured to the maximum, and the rigidity of the plate-shaped portion can be improved. In addition, in the above-mentioned divided portion, there may be a portion where gear teeth are not formed.

In the game machine A2 or A3, the gear teeth engraved on the first gear member and the gear teeth engraved on the second gear member are in an appropriate meshing state in which the relationship between the meshing gear teeth is fixed. The proper meshing state thereof is such that the first gear member is moved along the notch formed in the second gear member and is meshed with the second gear member. A game machine A4 characterized by being formed by a tooth.

According to the game machine A4, in addition to the effect of the game machine A2 or A3, the first gear member is moved along the outer shape of the notch portion of the plate-shaped portion of the second gear member to move the first gear member and the second gear member. When the gear members are meshed with each other, the gear teeth are meshed in a proper meshed state.

Therefore, when the first gear member and the second gear member are meshed with each other in a proper meshing state, the notch of the plate-shaped portion is used to align the first gear member and the second gear member at the time of meshing. It can be carried out. As a result, the meshing adjustment between the first gear member and the second gear member can be facilitated, so that the maintainability of gear replacement can be improved.

In addition, when the relationship of the teeth in which the first gear member and the second gear member mesh with each other is fixed, the rotating gear member to be meshed is an incomplete gear in which teeth are engraved on a part of the side surface. An example is a case where a moving rack member that reciprocates with respect to a rotating gear member is meshed with each other.

At the time of gear replacement, for example, which tooth of the second gear member is to be meshed with each tooth of the first gear member becomes a problem. In order to make the teeth mesh with each other, it is sufficient to prevent the gear teeth that mesh with each other from shifting by at least one tooth.

A5 of the gaming machines A1 to A4, characterized in that the moving resistance of at least one gear member of the first gear member or the second gear member increases at least at the specific phase position.

According to the gaming machine A5, in addition to the effects of the gaming machines A1 to A4, the movement resistance of at least one gear member of the first gear member or the second gear member increases at least at the specific phase position. Therefore, the maintenance worker can easily perform the work of engaging the pair of gear members (fitting the gear members at the proper meshing position) by relying on the increase in the movement resistance.

That is, when the first gear member and the second gear member are stopped in the middle of movement and the notch portion of the plate-shaped portion does not match the first gear member, the first gear member is pulled out. Even if you try, the plate-shaped part becomes an obstacle and cannot be pulled out. Therefore, it is necessary to move the second gear member. In this case, by moving the second gear member to a position where the resistance increases, the notch portion of the plate-shaped portion can be formed at a position matching the first gear member, and the first gear member can be pulled out. Becomes easier.

The movement resistance increases, for example, when a friction member that rubs against at least one of the first gear member or the second gear member is arranged at a specific phase position, or the first gear member or the first gear member at a specific phase position. An example is a case where at least one of the second gear members reaches the end of movement.

In the game machines A1 to A4, the first gear member and the second gear member are formed in such a manner that they are each moved to the end of movement, and the first gear member and the second gear member are arranged at each end of movement. When this is done, the gaming machine A6 is characterized in that the plate-shaped portion and the first gear member overlap at least a part in the rotation axis direction view of the first gear member.

According to the gaming machine A6, in addition to the effect of any of the gaming machines A1 to A4, when the first gear member and the second gear member are arranged at the end of movement, the rotation axis direction view of the first gear member At least a part of the plate-shaped portion and the first gear member overlap each other. That is, a specific phase position (a state in which the notch portion matches the first gear member) is formed at a position different from the moving end of the first gear member and the second gear member. Therefore, when the first gear member and the second gear member are moved and the first gear member approaches the specific phase position, the first gear member has a sufficient speed in the rotational direction (axis vertical direction). .. Therefore, the wobbling of the first gear member, which tends to occur at a specific phase position, can be alleviated by the momentum in the rotation direction of the first gear member.

The gaming machines A1 to A6 include a drive motor that generates a driving force, and the first gear member is pivotally supported by the drive motor in a pullable manner, and a layer between the drive motor and the first gear member. The gaming machine A7, characterized in that the plate-shaped portion is formed on the surface.

According to the gaming machine A7, in addition to the effects of the gaming machines A1 to A6, the first gear member is pivotally supported by the drive motor in a pullable manner.

Here, even if an attempt is made to engage the first gear member with the second gear member from the side where the plate-shaped portion is formed, the first gear member is brought into contact with the plate-shaped portion to prevent movement, so that the first gear member is prevented from moving. The gear member and the second gear member cannot be meshed with each other. Therefore, when the first gear member is pivotally supported by the drive motor, the arrangement position of the drive motor may be limited.

On the other hand, according to the gaming machine A7, since the first gear member can pass through the notch portion of the plate-shaped portion, the arrangement position of the drive motor is not limited in relation to the plate-shaped portion, and the driving motor is driven. The degree of freedom in disposing of the motor can be improved.

Further, since the plate-shaped portion of the second gear member is formed in the layer between the drive motor and the first gear member, the drive motor and the first gear member should be removed together when the drive motor is replaced. , You can choose to remove only the drive motor.

That is, the drive motor and the first gear member can be easily separated by pulling out the drive motor while keeping the first gear member in contact with the plate-shaped portion. By exchanging the drive motor in this way, the drive motor can be exchanged while maintaining the meshed state between the first gear member and the second gear member, and the first gear member and the second gear member can be exchanged again. It is possible to eliminate the need for meshing adjustment. This makes it possible to improve maintainability.

When the first gear member is pivotally supported in a manner that allows it to be pulled out from the drive motor, the first gear member is externally fitted and fixed to the drive shaft of the drive motor, or is attached to the tip of the drive shaft of the drive motor. An example is an example in which a plurality of pins are projected from the arranged adapter and the plurality of pins are inserted into the first gear member.

In the game machine A7, the first gear member is a shaft portion whose one end is fixed to the drive shaft of the drive motor and the other end of the shaft portion which is the opposite end of the one end. A rotating body portion connected to an end portion is provided, and the shaft portion and the rotating body portion are formed so as to be separable, and the shaft portion projects from the end surface of the other end portion in the axial direction. A plurality of projecting pins are provided, the rotating body portion includes a plurality of fitting portions into which the plurality of projecting pins are fitted, and the shaft portion and the rotating body portion are connected to the plurality of fitting portions. The gaming machine A8, characterized in that the projecting pins are formed by being fitted into the plurality of fitting portions.

Here, in order to bring the first gear member into contact with the plate-shaped portion and pull it out directly from the drive shaft of the drive motor, a force greater than the static friction generated between the drive shaft of the drive motor and the first gear member is required. Then, a force equal to or greater than the static friction is applied to the second gear member through the plate-shaped portion that comes into contact with the first gear member. Since the static friction is set to be large in order to maintain the phase relationship between the drive shaft of the drive motor and the first gear member, the plate-shaped portion may be deformed or excessive stress may be applied to the drive motor. ..

On the other hand, according to the gaming machine A8, in addition to the effect of the gaming machine A7, a plurality of protrusion pins are projected at the end of the shaft portion fixed to the drive shaft of the drive motor, and the protrusion pins project into the rotating body portion. A plurality of fitting portions into which the setting pins are fitted are formed. That is, by engaging the shaft portion and the rotating body portion at a plurality of points, the phase relationship between the drive shaft of the drive motor and the first gear member can be maintained without increasing the static friction.

Therefore, the force required to separate the drive motor and the rotating body portion of the first gear member can be reduced. Therefore, it is possible to prevent the plate-shaped portion of the second gear member from being deformed or excessive stress being applied to the drive motor.

Examples of the fitting portion include a through hole and a recess formed in a bottomed tubular shape.

In the gaming machine A7 or A8, it is arranged close to the drive motor and extends along the side surface of the motor case of the drive motor in a direction opposite to the extension direction of the drive shaft of the drive motor. A game machine A9 characterized by having a regulation unit.

According to the gaming machine A9, in addition to the effect of the gaming machine A7 or A8, when the drive motor is pulled out from the first gear member, the drive motor is pressed against the regulation portion extending along the side surface of the drive motor. Can be pulled out. As a result, it is possible to suppress the axial center of the drive motor from tilting with respect to the first gear member, and it is possible to suppress the deformation of the first gear member.

In the gaming machine A9, the restricting portions are formed in pairs with the motor case of the drive motor sandwiched between them, and the extending end of one of the restricting portions of the pair of restricting portions is the motor case of the drive motor. The gaming machine A10, which is an end surface of the machine A10 and is formed on the drive shaft side from the end surface on the opposite side of the end surface on which the drive shaft is arranged.

According to the gaming machine A10, in addition to the effect of the gaming machine A9, an extended end of one of the regulating portions formed in a pair is formed on the drive shaft side of the end surface of the motor case of the drive motor. Therefore, the extended end of one of the regulating portions can be effectively used as a fulcrum for pulling out the drive motor. That is, since the extension end of the regulation portion and the side surface of the drive motor are arranged adjacent to each other, the extension end of the regulation portion is used as a fulcrum and the side surface of the drive motor is used as a fulcrum when a force is applied to the drive motor. The distance to the point of action can be minimized. As a result, the force required for pulling out can be suppressed.

Further, when the drive motor is pulled out with the extended end of one of the regulating portions as a fulcrum, the drive motor can be pulled out while pressing the drive motor against the regulating portion on the opposite side of the one regulating portion. As a result, it is possible to suppress the degree of inclination of the drive motor with respect to the other gear when the drive motor is pulled out.

In the gaming machine A10, of the pair of the regulation parts, the other regulation part, which is the opposite side of the one regulation part, protrudes in the same manner as the extended end part of the one regulation part, or The gaming machine A11 is characterized in that it is formed so as to project from the extended end of one of the regulating portions to the opposite side of the drive shaft of the drive motor.

According to the gaming machine A11, in addition to the effect of the gaming machine A11, the other regulating portion to which the driving motor is pressed when the drive motor is pulled out is closer to the driving shaft of the driving motor than the extended end of at least one regulating portion. It is formed by overhanging to the opposite side. Therefore, when the drive motor is pulled out with the extended end of one regulating portion as a fulcrum, the point of action is closest to the other regulating section (that is, the point of action is a plane perpendicular to the drive axis of the drive motor). In a state where it is arranged on a plane including the extended end of one regulating portion), the movement of the drive motor can be prevented by the other regulating portion.

This makes it possible to reliably prevent the drive motor from moving in a direction away from one of the regulating portions when the drive motor is pulled out.

The game machines A7 to A11 include a moving contact member that is arranged so as to face the second gear member with the first gear member interposed therebetween, and the moving contact member is the first gear member at the specific phase position. It is arranged at a distance from the first gear member in the axial direction, and the plate-shaped portion of the second gear member overlaps the first gear member in the axial direction of the first gear member. The gaming machine A12 is characterized in that, in at least one of the states, the first gear member and the moving contact member overlap each other in the axial direction of the first gear member.

According to the gaming machine A12, in addition to the effects of the gaming machines A7 to A11, the first gear member simultaneously attaches to the plate-shaped portion of the second gear member and the moving contact member arranged to face the second gear member. Be abutted. As a result, the inclination of the first gear member when the first gear member is pulled out from the drive motor can be suppressed.

<Example of technical concept in which the starting gear tooth 452b1 for meshing is formed in a large size>
A driving gear member formed as a rotary gear and a driven gear member whose meshing is started during rotation of the driving gear member are provided, and at least one of the driving gear member and the driven gear member is hit at the start of meshing. A game characterized in that a meshing tooth to be in contact and an intermediate tooth that meshes when the meshing teeth are continued after the meshing teeth are meshed are provided, and the meshing tooth is formed larger than the intermediate tooth. Machine B1.

Here, there is a gaming machine in which meshing between the main gear member and the driven gear member (the side on which the rotation of the main gear member is transmitted) is started during the rotation of the main gear member (the side rotated by the drive motor). (See, for example, Japanese Patent Application Laid-Open No. 2013-244210). However, in the above-mentioned conventional gaming machine, the teeth that mesh with each other at the start of meshing between the main gear member and the driven gear member are liable to be damaged due to a collision at the beginning of meshing. On the other hand, if the gear teeth are enlarged, the gear teeth can be prevented from being damaged, but the backlash becomes large and it becomes difficult to smoothly rotate the driven gear member. Therefore, it has been difficult to achieve both durability and smooth rotation.

On the other hand, according to the gaming machine B1, since the meshing teeth are formed larger than the intermediate teeth, at least one of the main gear member and the driven gear member has the durability of the meshing teeth that mesh with each other at the start of meshing. It is improved and the damage of the meshing teeth can be prevented. In addition, since the backlash between the main gear member and the driven gear member can be reduced in the intermediate teeth, the rotation of the driven gear member during continuous meshing in which the intermediate teeth are meshed after the meshing teeth are meshed can be made smooth. can do. As a result, it is possible to improve the durability of the meshing teeth and the smoothness of rotation of the driven gear member at the same time.

The start of meshing means a state in which the meshing teeth formed on at least one of the driving gear member and the driven gear member start to come into contact with the other gear member on the opposite side of the one gear member.

Further, forming the meshing tooth in a large size means forming at least one of the tooth width, the tooth thickness or the tooth depth larger than that of the intermediate tooth.

The gaming machine B1 is characterized in that the gaming machine B1 includes a holding mechanism for holding the posture of the driven gear member.

According to the gaming machine B2, in addition to the effect of the gaming machine B1, a holding mechanism for holding the posture of the driven gear member is provided, so that the posture of the driven gear member is stabilized in a state where the driven gear member is not meshed with the main gear member. Can be done.

Examples of the holding mechanism include a mechanism for holding the driven gear member by sandwiching it in the axial direction, a mechanism for holding the driven gear member by mechanical alignment, and the like.

In the gaming machine B2, the driven gear member is provided with a notch portion that is cut out in a direction of retracting from the driving gear member, and the notch portion is brought into contact with the outer periphery of the driving gear member at at least two points. The gaming machine B3 is characterized in that the holding mechanism is formed by the machine.

According to the gaming machine B3, in addition to the effect of the gaming machine B2, a holding mechanism for holding the driven gear member can be formed by abutting the driven gear member and the driven gear member at two points. As a result, it is not necessary to dispose of another member for maintaining the posture of the driven gear member.

The notch portion may have a shape that does not interfere with the tooth tip circle of the driving gear member, and the shape is not limited, but at least the radius of curvature of the notch portion is that of the tooth tip circle of the driving gear member. It is formed below the radius.

The gaming machine B4 is characterized in that, in the gaming machine B3, the notch portion is formed as an arc-shaped concave portion circumscribing the driving gear member.

According to the gaming machine B4, in addition to the effect of the gaming machine B3, the notch portion of the driven gear member is brought into contact with the outer periphery of the driving gear member on a surface, thereby improving the effect of maintaining the posture of the driven gear member. Can be made to.

That is, the notch portion of the driven gear member is brought into contact with the outer periphery of the driving gear member on a surface, thereby suppressing the frictional force at the time of contact from being concentrated in one place, and the frictional force is applied to the entire notch portion. Can be dispersed. As a result, the number of places where the driven gear member is held by the driven gear member can be increased, and the effect of maintaining the posture of the driven gear member can be improved.

The mode in which the notch portion is circumscribed to the driving gear member is not particularly limited. That is, for example, it may be a mode in which the gear teeth are circumscribed to the tooth tip circle of the driving gear member, or a surface in which the gear teeth are omitted is formed on the driving gear member and is circumscribed on the omitted surface.

In the gaming machine B4, the contact point between the driving gear member and the notch portion of the driven gear member is drawn from the central axis of the driving gear member to the surface connecting the tooth bottoms of the driven gear member. A gaming machine B5 characterized in that it is formed on at least both sides of a perpendicular line.

According to the gaming machine B5, in addition to the effect of the gaming machine B4, the contact point between the driving gear member and the notch portion of the driven gear member is on the surface where the tooth bottom of the driven gear member is connected from the central axis of the driving gear member. Since it is formed on at least both sides of the drawn perpendicular line, it is possible to prevent the driven gear member from rotating (moving) in both directions in a state where the notch is in contact with the main gear member.

Examples of the driven gear member include a rotary gear member formed as a rotary gear, a rack gear formed as a gear that moves in parallel, and the like.

In any of the game machines B2 to B5, the driven gear member includes an engaging protrusion receiving portion formed larger than the meshing tooth, and the notch portion is formed in the engaging protrusion receiving portion. B6 ..

According to the gaming machine B6, in addition to the effect of any of the gaming machines B2 to B5, the driven gear member is durable by using the engaging protrusion receiving portion as a substitute for the tooth abutted on the driving gear member. The sex can be improved.

The engaging projectile receiving portion in which the notch is formed is not a part that originally plays a role of engaging with the gear teeth of the driving gear member, but is in contact with the outer peripheral surface of the driving gear member to change the posture of the driven gear member. It is a part of the role of maintaining. Therefore, unlike the gear teeth, the size is not limited according to the size of the gear teeth to be meshed. Therefore, the durability of the driven gear member is improved by using the engaging protrusion receiving portion, which is formed stronger than the gear tooth, at the portion where the main gear member and the driven gear member come into contact with each other at the start of meshing. Can be made to.

In the gaming machine B6, the driving gear member includes a recessed portion that is a recess formed adjacent to the meshing tooth, and the meshing tooth of the driving gear member is brought into contact with the engaging protrusion receiving portion. A gaming machine B7, wherein the driven gear member is rotated in a manner in which the engaging protrusion receiving portion enters the recessed portion.

According to the gaming machine B7, in addition to the effect of the gaming machine B6, the driven gear member is rotated before the meshing teeth of the driving gear member come into contact with the engaging protrusion receiving portion of the driven gear member, so that the driving gear member is rotated. The impact at the start of meshing with the driven gear member can be suppressed.

Here, when the driven gear member is in contact with the outer peripheral surface of the driven gear member at two points, the posture of the driven gear member is maintained even if the driven gear member rotates. On the other hand, when the meshing teeth of the main gear member are close to the engaging protrusion receiving portion of the driven gear member, the recessed portion formed adjacent to the engaging protrusion faces the engaging protrusion receiving portion. Since the recessed portion does not come into contact with the engaging protrusion receiving portion, the effect of maintaining the posture of the driven gear member is released. Then, the driven gear member is slightly rotated by the frictional force generated between the outer peripheral surface of the main gear member and the engaging protrusion receiving portion, and the engaging protruding receiving portion enters the recessed portion. As a result, the driven gear member starts rotating before the meshing teeth of the driven gear member are brought into contact with the engaging protrusion receiving portion of the driven gear member, so that the driven gear member and the driven gear member start meshing with each other. It is possible to suppress the impact when doing so.

<Example of technical concept in which the protruding gear member 7452e moves in the radial direction of the double-layer gear 7452>
A drive source that generates a driving force, a driving gear member that is rotated by the driving force of the driving source, a first moving member that is moved in conjunction with the rotation of the driving gear member, and a rotation of the driving gear member. The driven gear member that starts moving in conjunction with the driven gear member on the way, the second moving member that moves in conjunction with the movement of the driven gear member, and the driven gear member and the driven gear member are interlocked with each other. The first moving member is moved within a moving range from the moving base end to the moving end, and the driven gear member starts moving in conjunction with the driving gear member by the adjusting device. A gaming machine C1 characterized in that a plurality of positions of the first moving member can be formed at the time.

Here, in a gaming machine such as a pachinko machine, there is a gaming machine including a first moving member and a second moving member that are moved by a driving force of a single driving source (see, for example, Japanese Patent Application Laid-Open No. 2009-125022). ). However, in the above-mentioned conventional gaming machine, since the mode of the second moving member at a specific position during the movement of the first moving member is limited to one, there is a problem that there are few variations in the effect.

On the other hand, according to the gaming machine C1, a plurality of positions of the first moving member when the driven gear member starts to move in conjunction with the driven gear member can be formed by the adjusting device, so that the second moving gear member is linked with the driven gear member. A plurality of positions of the first moving member when the moving member starts moving can be formed. Therefore, it is possible to form a plurality of variations of the effects of the first moving member and the second moving member.

When the driven gear member starts to move in conjunction with the driven gear member, the driven gear member is moved by engaging the driven gear member and the driven gear member, or the driven gear member and the driven gear member are driven. The mode in which the driven gear member is moved by the friction generated between the gear members, or the magnetic force generated between the driven gear member and the driven gear member when the driven gear member and the driven gear member are formed of a magnetic material. An embodiment in which the driven gear member is moved is exemplified.

Further, as the forming mode of the adjusting device, at least one gear tooth of the driving gear member or the driven gear member is formed so as to be able to project in a direction away from the rotation axis, and between the shafts of the driving gear member and the driven gear member. An embodiment in which the distance can be changed is exemplified.

In the game machine C1, the interlocking of the driving gear member and the driven gear member is due to the meshing, and the adjusting device is arranged on the driving gear member and moves in the radial direction of the driving gear member. The projecting member is provided with a possible projecting member, and the projecting member is in an overhanging state in which the driven gear member is projected from the rotational direction of the driven gear member to a position where it can be contacted, and is in contact with the driven gear member from the rotational direction. An immersive state that is arranged at an impossible position can be formed, and when the main gear member rotates while the protruding member forms the overhanging state, the protruding member comes into contact with the driven gear member. The gaming machine C2 is characterized in that the engagement between the driving gear member and the driven gear member is started.

According to the gaming machine C2, in addition to the effect of the gaming machine C1, the way in which the main gear member and the driven gear member are interlocked differs depending on whether the protruding member of the adjusting device is in the overhanging state or the immersive state. Can be made.

Here, the start and release of the meshing between the driving gear member and the driven gear member can also be performed by changing the distance between the axes of the driving gear member and the driven gear member. However, in that case, in order to suppress the meshing resistance between the driving gear member and the driven gear member, it is necessary to move the rotating shaft in the direction perpendicular to the axis while maintaining the parallelism of the rotating shaft, and the accuracy of the moving parallelism is improved. Required. Therefore, the mechanism for moving the main gear member and the driven gear member may be complicated.

On the other hand, in the gaming machine C2, the main gear member is provided with a protruding member formed so as to be movable in the radial direction, and when the protruding member overhangs (when forming an overhanging state), the main gear member and the driven gear The meshing with the member is started. Therefore, it is not necessary to move the rotation shafts of the main gear member and the driven gear member, so that the parallelism of the rotation shafts is maintained. Therefore, accuracy is not required for the mechanism for moving the protruding member, and the mechanism for moving the protruding member can be simplified.

As a method of forming the projecting member in an overhanging state, a method of projecting the projecting member by centrifugal force generated when the main gear member is rotated, or a method in which a solenoid is arranged inside the projecting member and driven by the solenoid. An example is a method of projecting a protruding member. Further, the number of protruding members may be one or a plurality.

In the gaming machine C2, the protruding member receives the urging force generated toward the rotation shaft side of the driving gear member to form the immersive state at least in the stationary state of the driving gear member, and rotates the driving gear member. The gaming machine C3 is characterized in that it is formed so as to be able to switch between the immersive state and the overhanging state by switching the rotation speed to be caused.

According to the gaming machine C3, in addition to the effect of the gaming machine C2, by making the rotation speed of the driving gear member different, the protruding member comes into contact with the driven gear member and the protruding member is in contact with the driven gear member. It is possible to switch between the immersive state of idling.

As a result, the control of the operating speed of the drive source and the state of the projecting member can be interlocked with each other. Control can be simplified.

Examples of the member that generates the urging force include elastic springs such as coil springs and torsion springs, and members made of a rubber material having sufficient elasticity.

Further, a plurality of protruding members may be arranged on the main gear member in different phases. In this case, the amount of protrusion of each protruding member can be adjusted by adjusting the weight of each protruding member and the urging force acting on each protruding member.

In the game machine C2 or C3, the projecting member includes a first projecting member and a second projecting member formed in phase with the first projecting member, and the first projecting member and the second projecting member thereof. The amount of protrusion due to the rotation of the driving gear member is substantially the same, and the driving gear member has the first rotational speed at which the first protruding member and the second protruding member form the immersive state, and the first The 1-protruding member and the 2nd protruding member can form a second rotation speed that forms the overhanging state, and the rotation speed of the driving gear member is defined as the first rotation speed and the second rotation speed. The gaming machine C4 is characterized in that it can be switched between the two during the rotation of the driving gear member.

According to the game machine C4, in addition to the effect of the game machine C2 or C3, the phase at which the first protruding member starts to come into contact with the driven gear member by changing the rotation speed of the main gear member during rotation, and the first The driving gear member can be brought into contact with the driven gear member in at least two kinds of phases, which is the phase at which the protruding member starts to come into contact with the driven gear member.

That is, by rotating the main gear member at the first rotation speed and changing the rotation speed of the main gear member to the second rotation speed immediately before the first projecting member is positioned on the driven gear member side, the second rotation speed is obtained. The meshing with the driven gear member can be started by one protruding member. On the other hand, the main gear member is rotated at the first rotation speed, and the rotation speed of the main gear member is changed to the second rotation speed immediately before the second protruding member is positioned on the driven gear member side. Then, the second protruding member can start the meshing with the driven gear member.

In other words, by arbitrarily selecting the timing for increasing the rotational speed of the main gear member, the timing for projecting and immersing the protruding member can be arbitrarily selected. That is, even if the moving speed of the first moving member at the start of movement is the same, the timing of moving the second moving member can be changed by the timing of increasing the moving speed of the first moving member. As a result, it is possible to make it difficult to predict the subsequent effect only by checking the speed at the start of movement of the first moving member, and it is possible to improve the degree of attention of the movement of the first moving member and the second moving member. .. Therefore, the effect of the first moving member and the second moving member can be improved.

When the first projecting member and the second projecting member project with substantially the same amount of projecting, the masses of the first projecting member and the second projecting member are equal and act on each of them. When the forces are the same, or because the masses of the first protruding member and the second protruding member are different, the radial outward force generated by the rotation of the driving gear member is different, but each protrusion is in a manner that eliminates the difference. An example is a case where the urging force acting on the member is changed. For example, when the urging force is generated by the elastic spring, the spring constants of the elastic spring that gives the urging force to the first protruding member and the elastic spring that gives the urging force to the second protruding member are changed.

In the gaming machine C2 or C3, the protruding member is formed in phase with the first protruding member and the first protruding member thereof, and the first protruding member becomes the driven gear member during rotation of the main gear member. A second projecting member that is close to the driven gear member after being brought close to the member is provided, and the first projecting member and the second projecting member are formed so that the amount of projecting is different due to the rotation of the driving gear member. In the driven gear member, among the projecting members, the first projecting member forms an embedded state, and the second projecting member forms the overhanging state, and the separated rotational speed, and the first projecting member and The gaming machine C5 is characterized in that both of the second protruding members can form a joint rotation speed that forms the overhanging state.

According to the gaming machine C5, in addition to the effect of the gaming machine C2 or C3, a state in which the first protruding member is brought into contact with the driven gear member without changing the rotation speed of the driving gear member during rotation, and a second It is possible to form a state in which the protruding member is in contact with the driven gear member.

That is, when the driving gear member is rotated at a constant speed at the separated rotation speed, the driving gear member starts meshing with the driven gear member at the second protruding member. On the other hand, when the driving gear member is rotated at the joint rotation speed, the driving gear member starts meshing with the driven gear member at the first protruding member.

That is, in order to change the position of the first moving member when the second moving member starts moving, it is not necessary to change the rotation speed of the driving source during the rotation of the driving gear member, so that the control of the driving source is simple. Can be transformed into.
