A game machine such as a pachinko machine is equipped with a game board in which a game area in which the game ball flows down is formed on the front surface, and the game ball can be guided to the game area of the game board to play a game. Is common. In conventional gaming machines, the mainstream structure is to attach the gaming board from the back side of the gaming machine, but there is a problem that it takes time and effort to attach and detach the gaming board, resulting in poor efficiency. Therefore, for example, as disclosed in Patent Document 1, it has been proposed to have a structure in which the gaming board is attached from the front side of the gaming machine. In the structure described in Patent Document 1, the game board is arranged from the front side of the game machine, and the hook member is locked from the side to the side edge portion of the game board, so that the game board is placed at the mounting position. It is designed to be fixed. According to this, for example, it is possible to replace the game board from the front side while the game machine is installed in the game hall, so that the game board can be installed in a stable state. The replacement work can be performed and the work is easier, and when the replacement work of the gaming board is performed from the front side of the gaming machine, it is only necessary to open the front frame, so that the replacement work is performed from the back side. It also has the advantage that it does not take much time to open the gaming machine (Patent Document 1, Japanese Patent Application Laid-Open No. 6-47157).
By the way, especially in the case of a pachinko machine, it is important to accurately match the relative front-rear position of the front surface of the game board with respect to the launcher located below the game board, and if this relative position is displaced, the machine is fired. This causes a problem that the gaming ball fired from the device is not correctly introduced into the gaming area of the gaming board. In the past, as described above, the gaming board was attached from the back side of the gaming machine, so the gaming board was positioned in contact with the gaming machine body at the front. However, it was always constant, and the above-mentioned positional deviation was unlikely to occur. On the other hand, if the structure is such that the game board is attached from the front side of the game machine, the game board is positioned in contact with the game machine body on the back side, so that the thickness of the game board varies, for example. In some cases, there is a problem that the front-rear position of the front surface of the gaming board also varies, causing the above-mentioned positional deviation.
However, according to the above description of Patent Document 1, the locking position by the hook member is set so as to come to a fixed position at a distance of a predetermined thickness of the gaming board from the frame of the gaming machine main body to the front. However, the problem of positional deviation due to the variation in the plate thickness of the gaming board as described above is not taken into consideration. For this reason, for example, if the game board becomes thinner than the predetermined thickness due to variations in the plate thickness of the game board, the game board will rattle back and forth, while if the game board becomes thicker than the predetermined thickness, it will be locked by the hook member. In either case, it is difficult to accurately and stably align the front and rear positions of the front surface of the game board. Therefore, it must be said that the structure described in Patent Document 1 is insufficient in terms of positioning and stability of the game board. In other words, the structure described in Patent Document 1 is a structure in which the game board is attached from the front side of the game machine, so that the game board can be easily attached and detached. Although a new problem of variation in the front position of the game board has arisen, it can be said that this problem has not yet been considered.
The present invention has been devised in view of such problems, and an object of the present invention is to provide a gaming machine excellent in ease of attachment / detachment of a gaming board, positioning accuracy, and stability.
Hereinafter, the best mode of the present invention will be described in detail with reference to the drawings. Here, a pachinko gaming machine (hereinafter, simply referred to as a “pachinko machine”) is mentioned as a gaming machine.

(Configuration on the front side of the pachinko machine)
FIG. 1 is a front view of the pachinko machine 10, FIG. 2 is a perspective view of the pachinko machine 10, and FIG. 3 is a perspective view of the front frame of the pachinko machine 10. As shown in FIGS. 1 and 2, the pachinko machine 10 has an outer frame 11 forming an outer shell of the pachinko machine 10 and an inner frame 12 supported on one side of the outer frame 11 so as to be openable and closable. I have. Hereinafter, the configurations of the outer frame 11 and the inner frame 12 will be described individually.

The outer frame 11 is formed of a wooden plate material in a rectangular shape as a whole, and each plate material is assembled by a detachable fastener such as a machine screw. The outer frame 11 may be made of a light metal such as resin or aluminum. This is because the weight of the pachinko machine can be reduced by such a configuration.

On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) where the handle (game ball launching handle 18 described later) is installed when viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as the axis. In such a configuration, assuming that the opening / closing axis of the inner frame 12 is in the vertical direction on the side where the handle is installed (on the right side of the pachinko machine 10 in FIG. 1), the game ball launch handle is used when the inner frame 12 is opened. This is because the heads and the like of the 18 interfere with the adjacent pachinko machine and the card unit (ball lending unit), and the inner frame 12 cannot be sufficiently opened. The inner frame 12 is made of a synthetic resin, specifically, an ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantage of being highly viscous, resistant to impact, and being able to be manufactured at low cost is exhibited.

Further, the inner frame 12 has a lower plate unit 13 at the lowermost portion thereof, and has a front frame set 14 attached so as to be openable and closable with the vertical opening / closing axis on the left side of the inner frame 12 as the axis, and a resin base ( It is provided with a game board 30 (not shown) and a game board 30 described later, which is attached to the front side of the resin base.
Each of these configurations will be described in detail below.

The lower plate unit 13 is fixed to the front frame base member as a part of the front frame set 14. On the front side of the lower plate unit 13, a lower plate 15, a ball pulling lever 17, a game ball launch handle 18, and an effect button 79 are provided. The lower plate 15 as a ball receiving plate is provided in the substantially central portion of the lower plate unit 13, and has a role of stopping the game ball discharged from the discharge port 16 when the upper plate, which will be described later, is full. be. The ball pulling lever 17 is for pulling out a game ball in the lower plate 15, and by moving the ball pulling lever 17 to the left side in FIG. 1, a predetermined portion on the bottom surface of the lower plate 15 is opened. The game balls parked in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball launch handle 18 is arranged so as to project to the right side of the lower plate 15 toward the front side. In response to the operation of the game ball launch handle 18 by the player, the game ball is driven toward the game board 30 described later by the game ball launcher provided with the launch solenoid. A sound output port 24 for outputting sound from the speaker is provided on the upper portion of the front frame set 14.

On the other hand, at the lower part of the front frame set 14 (upper position of the lower plate 15 described above), an upper plate 19 as a receiving plate for the game ball is provided integrally with the front frame set 14. The upper plate 19 is a ball tray for temporarily storing the game balls and guiding them toward the game ball launching device 38 while arranging them in a row. Further, at the lower left of the upper plate 19, an effect button 79 is provided for the player to perform an operation such as changing the background of the decorative pattern display device 42.

In addition, the front frame set 14 is provided with light emitting means such as various lamps around the front frame set 14 (for example, a corner portion). These light emitting means play a role of enhancing the effect of the effect during the game by controlling the change of the light emitting mode such as lighting and blinking according to the change of the game state in the big hit game state and the like. For example, on the peripheral edge of the window portion 101, an annular illumination portion 102 having a built-in light emitting means such as an LED is provided symmetrically, and by lighting or blinking in the jackpot game state, the jackpot game state is in effect. It is a configuration to notify.

Further, a ball lending operation unit 120 is arranged below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button, a return button, and a frequency display unit. When the ball lending operation unit 120 is operated with bills, cards, etc. inserted into a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, game balls can be rented according to the operation. Will be done. The ball lending button is operated to obtain a lending ball based on the information recorded on the card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as the remaining amount is present on the card or the like. NS. The return button is operated when requesting the return of the card or the like inserted in the card unit. The frequency display unit displays the balance information of the card or the like. The ball lending operation unit 120 is not required for pachinko machines, so-called cash machines, in which game balls are lent directly from the ball lending device unit to the upper plate without going through a card unit. Therefore, a decorative sticker or the like is attached to the installation portion of the ball rental operation unit 120. As a result, it is possible to standardize the ball lending operation unit between the pachinko machine using the card unit and the cash machine.

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 4 is a front view showing the configuration of the game board 30. The game board 30 includes a general winning device 31 having a general winning opening, a variable winning device 32, a starting winning device 33 including a central starting port 33a, a right starting port 33b (composed of an operating chucker 33b), and a pair of opening / closing blades 60.

It is supposed to be given.

Here, the display contents of the special symbol display device, the ordinary symbol display device, and the decorative symbol display device 42 will be described. In the pachinko machine 10 of the present embodiment, a special symbol displayed by two special symbol display devices and a single decorative symbol display device 42 are displayed as symbols for indicating the occurrence of a jackpot to the player. There are two types of decorative patterns. A decorative symbol is a symbol that fluctuates in synchronization with the special symbol, starts fluctuating at the same time (or at about the same time) as the special symbol fluctuates, and at the same time (or at about the same time) as the special symbol stops fluctuating. To stop the fluctuation. This decorative pattern is provided in order to provide the player with a wide variety of display effects and to provide playability that is hard to get tired of.

First, the display contents of the special symbol performed by the first special symbol display device 371B and the second special symbol display device 371D will be described. The variable display of the special symbol is represented by the change of the lighting pattern of the eight LED segments. This variation display of the special symbol is started by either the first special symbol display device 371B or the second special symbol display device 371D based on the winning order when the game ball starts winning the winning device 33, and after a predetermined time. Stop. Specifically, after performing a total extinguishing process for stopping the lighting state of the special symbol display device on the corresponding side, a switching process for sequentially lighting each LED segment in a predetermined order is executed to start the fluctuation. When the fluctuation display time determined by the value of the stop pattern selection counter C3 described later elapses, the above-mentioned switching process is interrupted to perform all extinguishing processing, and the determination is made based on the values of the jackpot random number counter C1 and the jackpot symbol counter C2 described later. Each LED segment is lit according to the above-mentioned mode, and when displaying the loss result in the jackpot lottery, only one dot-shaped LED segment is lit and displayed, while when displaying the jackpot result, it is lit. , A number that differs depending on whether or not it is a winning that generates a high-probability gaming state after a big hit is lit and displayed using seven LED segments arranged in a "8" shape. During the period when one special symbol display device is in the variable display state, the other special symbol display device does not perform the variable display, and the symbol that was stopped and displayed at the last variable display is continuously lit. NS. The number of times the game ball has won a prize in the central starting port 33a and the right starting port 33b of the starting winning device 33 is held up to four times, respectively, and the number of holdings thereof is the number of holdings corresponding to the winning in the central starting port 33a. The first special symbol hold display device 371A and the decorative symbol display device 42 are displayed in predetermined areas, respectively, and the number of holds corresponding to the winning of the right starting port 33b is the second special symbol hold display device 371C and the decorative symbol display device. It is displayed in a predetermined area of 42. In addition, the hold lamp 800a of the decorative symbol hold display device 800 is used to hold the number of holds corresponding to the winning of the central starting port 33a according to the game state. The number of holds corresponding to the winning of the right starting port 33b is lit and displayed.

Next, the display contents of the decorative pattern display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol rows Z1 to Z3 are displayed in three display areas divided into upper, middle, and lower rows. These decorative pattern rows Z1 to Z3 are scrolled from right to left. The decorative symbol is composed of, for example, a main symbol composed of numbers "1" to "9" and a sub symbol smaller than the main symbol, and each of the main symbol and the sub symbol forms a symbol sequence of the decorative symbol. In each symbol sequence formed by the decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and the sub symbols are arranged between the main symbols. When a prize is awarded to the start winning device 33, that is, a start winning is generated, the decorative symbol is displayed in a variable manner, the variable display is stopped after a certain period of time corresponding to the variable pattern, and the decorative symbol display device 42 is vertically 3 × horizontal. Nine decorative symbols of 3 are displayed as display results. In the variable display that won the jackpot lottery, the display control device 45 controls the display control device 45 so that three identical main symbols are aligned and stopped on a vertical or diagonal straight line among the nine decorative symbols, and the player is informed. The occurrence of a jackpot is shown. On the other hand, in the variable display that is out of the jackpot lottery, the display control device 45 controls the display control device 45 so that three identical main symbols out of the nine decorative symbols are not stopped together in either the vertical or diagonal direction. The person is shown the occurrence of disengagement. When the gaming state does not include the support state (a state in which the pair of opening / closing blades 60 are easier to open than usual and the opening time is longer than usual), the hold lamp 800a of the decorative symbol hold display device 800 is used. While the number of holds corresponding to the winning of the central start port 33a is lit and displayed by emitting red light, when the game state includes the support state, the hold lamp 800a of the decorative symbol display device 800 is used to display the right start port. The number of holds corresponding to the winning of 33b is lit and displayed.

Next, the display contents of the ordinary symbol performed by the ordinary symbol display device 371E will be described. The variation display of the ordinary symbol is expressed by alternately lighting the above-mentioned two LEDs. The variation display of the normal symbol is started on condition that the game ball passes through the passage port of the operation winning device 34, and the variation display of the normal symbol is stopped after a predetermined time. Then, when both LEDs are stopped in the lit state, the start winning device 33 is in the operating state for a predetermined time (the pair of opening / closing blades 60 are opened). The number of times the game ball has passed through the passage port of the operation winning device 34 is held up to four times, and the number of times held is lit and displayed on the normal symbol hold display device 371F.

(When the power is turned on)
When the power of the pachinko machine 10 is turned on, each part such as a speaker, a liquid crystal screen of the decorative symbol display device 42, various LEDs arranged in a frame, and various LEDs arranged in the game board 30 is specified as an operation check and a power-on notification. It is set to perform a predetermined operation for a time (30 seconds in this embodiment). Therefore, it is possible to visually confirm whether or not each of these parts functions normally. At this time, it can also be confirmed whether or not the pachinko machine 10 has been tampered with illegally.

Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to perform a big hit lottery, set a symbol display of the special symbol display device, and the like. Specifically, it includes a counter group related to a special symbol and a counter group related to a normal symbol. First, the counter group related to the special symbol will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selecting the jackpot symbol of the special symbol display device, and the special symbol display device when the special symbol display device is disengaged and fluctuates. The initial value used to set the initial value of the stop pattern selection counter C3 used for selecting the stop pattern (corresponding to the reach lottery of whether to reach or completely deviate in the fluctuation of the decorative pattern) and the jackpot random number counter C1. It includes a random number counter CINI1 and variable type counters CS1 to CS3 for determining the type used for selecting the variable pattern.

Here, the fluctuation pattern means each pattern (form) when those having common characteristics of the fluctuation display are classified.

The counters C1 to C3, CINI1, CS1 to CS3 are loop counters in which 1 is added to the previous value each time the counter is updated, and the counter returns to 0 after reaching the maximum value. Each counter is updated at short intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a hold ball storage area 700 including one execution area and four hold areas (hold first to fourth areas), and each of these areas is used to play a game for the start winning device 33. Each value of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 is stored according to the winning timing of the ball.

Next, the specific contents of each counter will be described in detail.
The jackpot random number counter C1 has a configuration in which, for example, 1 is added in order within the range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 738), is updated once for each timer interrupt, and is within the remaining time of normal processing. It is updated repeatedly with. The jackpot random number counter C1 is periodically updated (once for each timer interruption in this embodiment), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33. The number of random number values that will be a big hit is set for two types, low probability time and high probability time, and the number of random number values that will be a big hit at low probability time is 2, and the value is "373,727". Yes, the number of random numbers that will be a big hit at high probability is 14, and the value is "59,109,163,211,263,317,367,421,479,523,557,631,683,733". be. In addition, the high probability time refers to a state in which the combination of special symbols becomes a big hit by the combination of specific symbols which are predetermined probability fluctuation symbols, and the subsequent jackpot probability increases as an added value, that is, the so-called probability change time. The time (low probability time) means the case where it is not in such a probabilistic state.

The jackpot symbol counter C2 determines the symbol when the fluctuation of the special symbol is stopped in the special symbol display device at the time of the jackpot. For example, 1 is added in order within the range of 0 to 4, and the maximum value (that is, 4) is added. It is configured to return to 0 after reaching. For example, in the stop symbol when the values of the jackpot symbol counter C2 are "0" and "1", nine LED segments stop in a specific lighting pattern, and the combination of the stop symbols in this case is a non-specific symbol (normally). It means the jackpot design).

In the stop symbol when the value of the jackpot symbol counter C2 is "2", "3", "4", nine LED segments stop in a specific lighting pattern different from the above, and the stop symbol in this case The combination means a specific symbol (probability fluctuation symbol).

The jackpot symbol counter C2 is periodically updated (once for each timer interruption in this embodiment), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

The stop pattern selection counter C3 is configured to be incremented by 1 in order within the range of 0 to 238, and return to 0 after reaching the maximum value (that is, 238). In this embodiment, since the variable display of the special symbol is configured to be represented by nine LED segments, there is no concept of reach in the case of the special symbol, and the stop pattern corresponding to the reach is set as the stop pattern selection counter C3. Will be decided by. On the other hand, in the case of a decorative symbol, there is a reach because the three decorative symbols stop. Therefore, in the case of a decorative pattern, the reach lottery is determined by the stop pattern selection counter C3. That is, in the case of a decorative symbol, the final stop symbol is shifted by one before and after the reach symbol to stop after the reach occurs, and the final stop symbol is other than before and after the reach symbol. A lottery will be drawn for "reach other than front and rear disengagement" to stop and "complete disengagement" where reach does not occur. For example, the stop pattern selection counters C3 = 0 to 201 correspond to complete deviation, the stop pattern selection counters C3 = 202 to 208 correspond to the front / rear deviation reach, and the stop pattern selection counters C3 = 209 to 238 correspond to the reach other than the front / rear deviation. Applicable.

Here, "reach" means that after the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts to be displayed in a variable manner, the combination of the symbols that stop first is the same symbol (in the case of a decorative symbol having a plurality of effective lines). A combination of jackpot symbols that suggests to the player that the symbol will be a jackpot depending on the display result of the symbol that is the same symbol on one of the effective lines and satisfies the jackpot condition and continues to be displayed in a variable manner. It is a display that makes the player expect, and is a kind of entertainment production. The hobby effect is to display a predetermined symbol represented by reach on the display screen of the decorative symbol display device 42 in the middle of the variable display, output a specific sound from the speaker, or use a vibration motor. This is an effect that makes the player expect that the display result after the variable display will be a big hit by vibrating the game ball launching handle 18 and other modes different from the usual ones along with the variable display.

The stop pattern selection counter C3 is periodically updated (once for each timer interruption in this embodiment), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

The variation type counter CS1 is configured to be incremented by 1 in order within the range of 0 to 198, and return to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is configured to be incremented by 1 in order within the range of 0 to 240, and return to 0 after reaching the maximum value (that is, 240). The variation type counter CS3 has a configuration in which, for example, 1 is added in order within the range of 0 to 162, and after reaching the maximum value (that is, 162), it returns to 0.
The variable type counter CS1 determines a rough symbol variation mode such as the reach type such as normal reach, super reach, special reach, premium reach, etc., and the variable type counter CS2 further determines, for example, normal reach A, normal reach B, etc. A detailed symbol variation mode is determined, and the variation type counter CS2 determines addition / subtraction of the variation time in the case of, for example, a slip stop variation. Therefore, by combining these fluctuation type counters CS1 to CS3, a wide variety of fluctuation patterns can be easily realized.

The counters CS1 to CS3 are updated once each time the normal processing described later is executed once, and are repeatedly updated even within the remaining time in the normal processing. Then, the buffer values of the counters CS1 to CS3 are acquired when the fluctuation pattern is determined at the start of the fluctuation of the special symbol by the special symbol display device and the decorative symbol by the decorative symbol display device 42.

Next, the counter group related to the ordinary symbol will be described. The counter group related to the ordinary symbol includes a hit random number counter C4 used for the winning lottery and an initial value random number counter CINI2 used for setting the initial value of the winning random number counter C4.

The hit random number counter C4 is a loop counter in which 1 is added to the previous value each time it is updated, and after reaching the maximum value, it returns to 0. The counter is updated at short intervals, and the updated value is appropriately stored in the counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a hold ball storage area 701 consisting of one execution area and four hold areas (hold first to fourth areas), and each of these areas is provided with a game for the operation winning device 34. The value of the hit random number counter C4 is stored according to the passage of the sphere.

Next, the specific contents of the hit random number counter C4 and the initial value random number CINI2 will be described in detail. The hit random number counter C4 is configured to be incremented by 1 in order within the range of 0 to 250, and return to 0 after reaching the maximum value (that is, 250). Then, when the hit random number counter C4 makes one round, the value of the hit initial value random number counter CINI2 at that time is read as the initial value of the hit random number counter C4. The initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the hit random number canter C4 (value = 0 to 250), is updated once for each timer interrupt, and is within the remaining time of normal processing. It is updated repeatedly with. The winning random number counter C4 is periodically updated (once for each timer interruption in this embodiment), and is stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the operation winning device 34. The number of hit random number values of the hit random number counter C4 is 149, and the value is "5 to 153".

The size and range of each counter are only examples and can be changed arbitrarily. However, if irregularity is emphasized, the sizes of the jackpot random number counter C1, the stop pattern selection counter C3, the hit random number counter C4, and the variation type counters CS1 to CS3 are all different prime numbers, and are not synchronized in any case. It is desirable to keep it.

The details of each control process executed by the MPU 501 in the main control device 261 will be omitted here.
However, in summary, as described above, the winning of the starting winning device 33 causes the main control device 261 to draw a winning / failing lottery with a predetermined probability, and upon winning, the game shifts to a special gaming state. The variable winning device 32 is in the receiving state of the winning ball.

The first rotating shaft 81 is inserted between the face plate 76 and the fourth face plate 77, and the shaft insertion portion 72C is aligned with the first shaft insertion holes 76P and 77P of the third face plate 76 and the fourth face plate 77. It is inserted and fixed with an E-shaped retaining ring (not shown) on the outer surface side of each of the third face plate 76 and the fourth face plate 77, so that the shaft is rotatably supported. A first torsion coil spring 83 is interposed between the movable hook 72 and the fourth face plate 77 in a state of being externally fitted to the first rotation shaft 81. The tip of the arm 83M on the movable hook 72 side of the first torsion coil spring 83 is bent in an annular shape and is hooked on the hook boss 72E of the movable hook 72 as shown in FIG. 16, while the fourth face plate 77. The tip of the arm 83N on the side is folded back in a U shape toward the fourth face plate 77 side and is hooked on the extending piece portion 77E of the fourth face plate 77 as shown in FIG. As a result, the movable hook 72 is urged in the direction in which the locking portion 72H is further away from the first face plate 74 of the base 71 (in the clockwise direction as shown by the arrow A11 in FIG. 16).

A lock member 84 is mounted between the movable hook 72 and the second face plate 75 of the base 71. As shown in FIG. 21, the lock member 84 extends in a substantially rectangular shape that fits within the base 71 corresponding to the outer shape (rectangle) of the second face plate 75 of the base 71, and one end edge (the lower left edge in FIG. 21). And its both side edges extend to one side (upper surface side in FIG. 21) in a rectangular shape with a U-shaped cross section, and is made of the same resin as the resin constituting the movable hook 72 described above. There is. A gripping surface 84G is formed by projecting several ribs extending along the extending direction on the outer surfaces of both side pieces of the peripheral wall-shaped extending portion. A regulation surface 84L perpendicular to the extending direction of the peripheral wall-shaped extending portion is formed at a position slightly inward from the extending end (slightly below the upper end in FIG. 21) inside the peripheral wall-shaped extending portion. From the regulation surface 84L, the height of the peripheral wall-shaped extension portion in the extension direction gradually decreases toward the other end side (upper right end side in FIG. 21) of the lock member 84. 84S is formed. Both sides of the guide surface 84S are flush with both side pieces in the peripheral wall-shaped extending portion. The peripheral wall-shaped extending portion, the regulating surface 84L, the guide surface 84S, and the like are all formed into a wall shape having a predetermined thickness, and are integrally continuous at the boundary portion. With the above configuration, one end portion (lower left portion in FIG. 21) of the lock member 84 is formed into a shape that bulges into a hollow shape in a substantially trapezoidal shape toward one surface side (upper surface side in FIG. 21) as a whole. Has been done. As shown in FIG. 17, the side surface opposite to the regulation surface 84L (lower surface in FIGS. 17 and 21) in the bulging portion is opened, and at the position of the boundary between the regulation surface 84L and the guide surface 84S in the bulging portion. A partition wall 84P parallel to the end surface of the bulging portion (the left front end surface in FIGS. 17 and 21) is formed, and the space inside the bulging portion is formed into a substantially rectangular parallelepiped shape inside the regulation surface 84L by the partition wall 84P. The shape is divided into a space and a space having a substantially triangular columnar shape inside the guide surface 84S.

As shown in FIG. 21, in the lock member 84, the peripheral edge of the portion extending from the substantially trapezoidal bulging portion to the other end side (upper right end side in FIG. 21) is the extending height of the peripheral wall-shaped extending portion. It is formed into a peripheral wall shape having an extension height smaller than that of the halfbeak, and as a whole, it has a substantially rectangular dish shape thinner than the bulging portion. In other words, a recess 84N is formed so as to be surrounded by the peripheral wall-shaped portion and the guide surface 84S so as to form a substantially rectangular dish shape and recess. Inner rails 84R extend to both sides from the extending end edges of both sides of the peripheral wall-shaped portion. The inner rail 84R extends linearly from the concave portion 84N side end (upper right side end in FIG. 21) of the lock member 84 to the vicinity of the gripping surface 84G. On both sides of the recess 84N, regulation ribs 84M are formed below the inner rail 84R, respectively.

As shown in FIG. 18, the lock member 84 has a surface (lower surface in FIG. 18) opposite to the bulging portion forming side of the substantially trapezoidal shape mounted on the second surface plate 75 of the substrate 71. , Is inserted into the substrate 71 from the recess 84N side. At this time, the inner rail 84R of the lock member 84 enters the inner side of the outer rails 76R and 77R of the base 71 (lower side in FIG. 18), whereby the lock member 84 is regulated so as not to move up and down, and the second face plate. The top of the 75 is held so that it can slide along its length direction (lower left to upper right in FIG. 18). At this time, while the locking member 84 is being inserted, the regulating rib 84M conflicts with the regulating rib (not shown) of the base 71, but the third face plate 76 and the fourth face plate 77 are forcibly press-fitted while being elastically deformed. To do. After press fitting, the regulation rib 84M of the lock member 84 is restricted from moving by the regulation rib of the base 71, whereby the lock member 84 is restricted from being pulled out from the base 71 beyond a predetermined distance.

As shown in FIG. 22, the pusher 73 extends in a substantially rectangular shape (approximately band shape) in front view corresponding to the outer shape (rectangle) of the first face plate 74 of the base 71, and is substantially one end side half. The portion (upper end side half in FIG. 21) bulges toward one side (lower left side in FIG. 21) in the thickness direction, while the other end side half (lower end side half in FIG. 21) bulges in the thickness direction. A curved surface that meanders in a substantially S-shape in a side view is formed so as to be slightly recessed, and a shape in which roughly cloud-shaped side walls perpendicular to the curved surface are formed on both sides of the curved surface. It is made of the same resin as the resin constituting the movable hook 72 described above. The pressing surface 73E is formed by the bulging curved surface on one end side half. A partition parallel to the side wall is formed at the center in the width direction inside (the back side in FIG. 21) of the pressing surface 73E forming side end portion (upper end portion in FIG. 21) (not shown). Further, ribs extending in the width direction are formed at the central portion in the length direction and the end portion (lower end portion in FIG. 21) opposite to the pressing surface 73E forming side on the inner side (not shown). A shaft insertion opening 73P that penetrates the pusher 73 in a straight line in the width direction is formed on both side walls and the partition wall.

As shown in FIG. 18, the pusher 73 has the shaft insertion opening 73P forming side end (upper end in FIG. 18) directed toward the fifth face plate 78 side of the base 71, and the opposite side surface of the pressing surface 73E is the first side of the base 71. The second time, the shaft insertion opening 73P is housed in the base 71 in a position facing the first face plate 74, and the shaft insertion opening 73P is aligned with the second shaft insertion holes 76S and 77S of the third face plate 76 and the fourth face plate 77. The moving shaft 85 is inserted and fixed with an E-shaped retaining ring (not shown) on the outer surface side of each of the third face plate 76 and the fourth face plate 77, so that the shaft is rotatably supported. A second torsion coil spring 86 is fitted inside the pusher 73. The second torsion coil spring 86 is a double torsion spring integrally having two coils 86C, a U-shaped central arm 86M between both coils 86C, and end arms 86E extending further on both sides of both coils 86C. It has become. As also shown in FIG. 17, the second torsion coil spring 86 has both coils on the inside (back side in FIGS. 17 and 18) of the pressing surface 73E forming side end portion (upper end portion in FIGS. 17 and 18) of the pusher 73. Align the center arm 86M with the position of the shaft insertion opening (not shown) with the partition wall sandwiched between the 86Cs, and align the center arm 86M with the end side opposite to the pressing surface 73E forming side end of the pusher 73 (FIGS. 17 and 18). In the downward direction) and gradually away from the pusher 73, that is, in the lower right direction in FIGS. 17 and 18, the end arm 86E is directed to the end opposite to the pressing surface 73E forming side end of the pusher 73. It is arranged in a lateral direction (downward in FIGS. 17 and 18) and gradually approaches the back surface of the pressing surface 73E, that is, in the lower left direction in FIGS. 17 and 18, and the second rotation as described above. By inserting the coil 86C together with the coil 86C while the shaft 85 is being inserted, the coil 85 is fitted onto the second rotating shaft 85. The tip of the central arm 86M of the second torsion coil spring 86 abuts on the first face plate 74 of the substrate 71, while the tip of the end arm 86E extends along the back surface of the pressing surface 73E on the pusher 73 (FIGS. 17 and 17 and). It is bent downward in FIG. 18), and the bent portion is arranged so as to abut against the back surface of the pressing surface 73E. As a result, the pusher 73 approaches the locking portion 72H of the movable hook 72 with one end pivotally supported by the second rotation shaft 85 (counterclockwise as shown by arrow A12 in FIG. 16). It is designed to be urged in the clockwise direction).

As shown in an exemplary manner in FIG. 9, the first hooking device 70A has the third face plate 76 and the fourth face plate 77 of the base 71 on the upper side and the lower side, and the second face plate 75 and the fifth face plate 78 on the right side and the fifth face plate 78. The first face plate 74 is arranged on the left side in front of the inner frame 12 with the first face plate 74 facing the rear side, and is fastened and fixed by screws with the screw insertion piece 74T of the base 71.

Hereinafter, the procedure for attaching the game board 30 using the first hooking device 70A will be sequentially described.
(A) Before the mounting work, normally, as shown in FIGS. 23 and 24, the movable hook 72 of the first hooking device 70A is set to the closed position. If the movable hook 72 and the lock member 84 are projected forward, they are more likely to receive contact from the surroundings and are more likely to be damaged, and are also likely to interfere with the surrounding work. Therefore, the movable hooks are thus movable hooks. It is desirable to store (retract) the 72 and the lock member 84.

In the closed position, as shown in FIG. 24, the right side surface of the rotating body portion 72D of the movable hook 72 abuts on the regulation surface 84L of the lock member 84, whereby the locking portion 72H of the movable hook 72 is brought into contact with the game board 30. It is regulated so that it cannot rotate in a direction away from the board surface (counterclockwise in FIG. 24). That is, the movable hook 72 is locked to the closed position by the lock member 84.

On the other hand, as shown in FIGS. 9 and 23, the fixing hook 87 is arranged and fixed at a position corresponding to substantially the center in the height direction on the left edge of the game board 30 on the front surface of the inner frame 12. The fixed hook 87 has a substantially U-shaped cross section that can include the left edge of the game board 30, and is a member that extends slightly long in the vertical direction. Although not shown in FIG. 9, as shown in FIG. 23, the ridge angle portion on the inside of the tip (upper right side in FIG. On the other hand, the rear side piece 87R is provided with a pressing piece 88 that presses the game board 30 from the rear to the front so as to easily receive the 30. The configuration and mounting structure of the pressing piece 88 are the same as those of the pusher 73 in the first hooking device 70A described above, and thus the description thereof will be omitted. The fixed hook 87 is immovable (while the movable hook 72 in the first hooking device 70A described above is movably configured, the fixed hook 87 always maintains a substantially U-shaped cross section except for the operation of the pressing piece 88. It is a non-movable) hook member.

(B) At the time of mounting work, first, as shown by arrow A13 in FIGS. 23 and 24, the lock member 84 of the first hooking device 70A is pulled out to the front of the pachinko machine 10, thereby showing in FIGS. 25 and 26. As described above, the movable hook 72 is set in the open position. The lock member 84 can be gripped by pinching the gripping surface 84G and easily slid and pulled out. As shown in FIGS. 25 and 26, when the entire gripping surface 84G reaches a position slightly protruding forward from the base 71, as described above, the regulation rib 84M of the lock member 84 is restricted from moving by the regulation rib of the base 71. As a result, the lock member 84 is restricted from being pulled out forward from this position. That is, this position is the forward movement limit position of the lock member 84. As the lock member 84 is pulled forward to the movement limit position in this way, the regulating surface 84L is displaced forward from the rotating body portion 72D of the movable hook 72, and the restriction on the operation of the movable hook 72 is released. Since the movable hook 72 is urged by the first torsion coil spring 83 described above, the urging force causes the movable hook 72 to come out forward as shown by arrow A14 in FIGS. 25 and 26 (in FIGS. 25 and 26). Rotate counterclockwise). At this time, the curved surface of the protruding corner of the movable hook 72 rotates along the guide surface 84S of the lock member 84. When the movable hook 72 is rotated forward by about 45 ° from the closed position as shown in FIGS. 25 and 26, the right side surface of the rotating body portion 72D is on the front surface of the right side portion (recessed portion) of the pusher 73. At the end, further rotation is blocked. That is, this position is the forward rotation limit position of the movable hook 72, and is the open position.

(C) Then, as shown in FIG. 27, the game board 30 is tilted so that the right side is farther from the pachinko machine 10, and the left end edge thereof is inserted into the fixed hook 87 from the front right side. It is hooked inside the piece 87F.

(D) Then, as shown by arrow A15 in FIG. 27, the game board 30 is rotated so as to close the door (counterclockwise in FIG. 27) around the above-mentioned hooking position of the left edge. Then, as shown in FIG. 28, the right end portion is fitted to the position where it abuts on the pusher 73 of the first hooking device 70A.

At this time, the ridge angle portion on the left rear side of the game board 30 touches the pressing piece 88 of the fixed hook 87 and receives some resistance, but by rotating the game board 30, a large lever force acts on the ridge angle portion. Therefore, as shown in FIG. 28, the left end edge of the game board 30 is the front side piece 87F and the rear side piece 87R of the fixed hook 87 while the ridge angle portion easily pushes the pressing piece 88 backward against the elasticity. It fits between. After the left end edge of the game board 30 is fitted into the fixed hook 87, the pressing piece 88 elastically presses the game board 30 against the front piece 87F of the fixed hook 87 from the rear, so that the left end of the game board 30 The front surface is always held at the position of the inner side surface of the front side piece 87F of the fixed hook 87. With this configuration, even if the plate thickness of the game board 30 varies, the front surface of the left end portion of the game board 30 is held so as to be surely in a predetermined position. In other words, the elasticity of the pressing piece 88 makes it possible to attach the front surface of the game board 30 to a predetermined front-rear position while absorbing variations in plate thickness.

On the other hand, in the first hooking device 70A, since the movable hook 72 is set in the open position, the right end portion of the game board 30 can be easily fitted. At this time, instead of the first hooking device 70A, for example, a hooking device 89 having a configuration as shown in the manner shown in FIG. 29 (hereinafter, also referred to as a “reference hooking device”) 89 can be used. However, according to this reference hooking device 89, there is a disadvantage as compared with the above-mentioned first hooking device 70A. In the reference hooking device 89 shown in the figure, the movable hook 90 has a substantially U-shaped cross section that can include the right edge of the game board 30, and when the game board 30 is attached or detached, the reference hook 90 has a substantially U-shape. As shown in FIG. 29, the movable hook 90 is rotated diagonally forward and set in the open position. In this configuration, the portion that contacts the front surface of the game board 30 and the portion that contacts the rear surface are integrated in a substantially U-shaped cross section, so that the number of parts is small and the configuration is simple. There are advantages. However, the space for receiving the game board 30 in the movable hook 90, that is, the distance between the front and rear side pieces, is always only a constant dimension substantially equal to the thickness of the game board 30, and does not expand beyond this. It is difficult to insert the game board 30. Further, since the elastic force of the pusher 91 is immediately received from the time when the game board 30 is inserted, an extra force is required until the game board 30 is fitted to the mounting position. On the other hand, when the game board 30 is removed from the mounting position, the game board 30 is inevitably pulled forward together with the movable hook 90 being set to the open position, and therefore the game board 30 is surely pulled out. There is also a problem that it may fall vertically if it is not supported.

On the other hand, in the first hooking device 70A, the pusher 73 is arranged at a certain rear (back) position along the front surface of the inner frame 12 regardless of the rotation (displacement) of the movable hook 72. Since it is substantially immobile by moving slightly back and forth due to pressing, when the movable hook 72 is in the open position, the space between the movable hook 72 and the pusher 73 is greatly expanded to provide a space for receiving the game board 30. It can be expanded and therefore the game board 30 can be easily fitted. That is, throughout the process of fitting the game board 30 into the mounting position, the pusher 73 is in a state of waiting at a certain rear (back) position and does not conflict with the game board 30, while FIGS. 27 and 28. As shown in the above, the movable hook 72 in the open position deviates from the rotation trajectory of the game board 30. Therefore, since the space between the game board 30 and the mounting position is completely open and there is no conflicting object, the game board 30 can be fitted into the mounting position very easily. Further, since the pusher 73 does not conflict with the game board 30 until it reaches the mounting position, no resistance as well as elastic force is generated to the game board 30 during that time. On the other hand, when the game board 30 is removed from the mounting position, the movable hook 72 can be moved to the open position while the game board 30 is left in the mounting position. Since the game board 30 is supported by the inner frame 12 at the mounting position, it is necessary to hold the game board 30 so that it does not fall forward just by removing the movable hook 72, but there is a risk that the game board 30 will fall vertically. Therefore, it is safer than the case of the reference hook device 89.

(E) Then, as shown in FIG. 30, the movable hook 72 of the first hooking device 70A is returned to the closed position again. At this time, as shown by the arrow A16 in FIG. 30, the lock member 84 is pushed backward of the pachinko machine 10. As the lock member 84 is pushed in this way, the guide surface 84S of the lock member 84 functions as a cam surface, and the curved surface of the protruding corner at the bent portion of the movable hook 72 is shown by arrow A17 in FIG. , The first torsion coil spring 83 is guided to rotate in the direction of being retracted backward (clockwise in FIG. 30) against the urging force. In this way, when the movable hook 72 rotates about 45 ° rearward from the open position, the right side surface of the rotating body portion 72D of the movable hook 72 comes into contact with the restricting surface 84L of the lock member 84 again, whereby the movable hook 72 is movable. The hook 72 is locked (regulated) to the closed position again by the lock member 84.

At this time, although some resistance is received by the elastic force of the pusher 73 via the game board 30, by pushing the lock member 84 backward, the right end portion of the game board 30 is fitted into the mounting position as shown in FIG. be able to. After the right edge of the game board 30 is fitted into the mounting position and the movable hook 72 of the first hooking device 70A is locked to the closing position, the pusher 73 is elastic as in the case of the left edge described above. The game board 30 is pressed against the locking portion 72H of the movable hook 72 from behind, while the locking portion 72H of the movable hook 72 is locked in the closed position and is held immovably, so that the right side of the game board 30 is held. The front surface of the end portion is always held at the position of the inner side surface of the locking portion 72H of the movable hook 72. With this configuration, even if the plate thickness of the game board 30 varies, the front surface of the right end portion of the game board 30 is held so as to be surely in a predetermined position. In other words, the elasticity of the pusher 73 makes it possible to attach the front surface of the game board 30 to a predetermined front-rear position while absorbing variations in plate thickness.

According to the above mounting process, as described above, even if the plate thickness of the game board 30 varies, the left and right side ends of the game board 30 are fronted by the fixed hooks 87 and the first hooking device 70A, respectively. Although the front-rear position can be accurately aligned with the predetermined position for mounting, the game board 30 can be mounted by using the fixed hook 87 and the first hooking device 70A, especially the first hooking device 70A. It can be done to your advantage.

In the first hooking device 70A, the movable hook 72 can be moved to the closing position and the opening position by the operation of pushing in and pulling out the lock member 84, so that the operation is easy. Further, in particular, the lock member 84 is arranged separately from the movable hook 72 so that it can operate without contacting the front surface of the game board 30, and pushes the game board 30 against the elastic force of the pusher 73. In this case, since it is not necessary to push the game board 30 while directly contacting it, it is possible to reduce damage such as scratches and dirt on the surface (front surface) of the game board 30. Further, at this time, since the movable hook 72 and the pusher 73 that come into contact with the game board 30 are made of resin, the damage to the game board 30 is further reduced, and in addition, the base 71 and the lock member 84 are also combined. Since the entire first hooking device 70A is basically made of resin, the first hooking device 70A is lightweight and inexpensive. Furthermore, in the movable hook 72, the corner inside the tip portion that easily contacts the game board 30 is formed into a shape with a corner drop, while in the pusher 73, the surface facing the game board 30 gently bulges into a curved surface shape. The shape of the movable hook 72 and the pusher 73 also reduces the damage to the game board 30.

Further, since the movable hook 72 is configured to move in a direction substantially orthogonal to the surface (front surface) of the game board 30 by rotating, it is configured to abut and separate from the game board 30. There is less damage to the surface (especially damage from friction).

Further, both the movable hook 72 and the lock member 84 are configured to move in a direction orthogonal to the game board 30, that is, in a front-rear direction of the pachinko machine 10 by rotating or reciprocating, so that the operation can be performed. The required area does not spread around the first hooking device 70A (that is, outward along the board surface direction of the game board 30), but fits within the area corresponding to the front shape of the first hooking device 70A. It has become. For example, if the operating area is configured to expand to the surroundings by rotating or sliding the hook or operating member, it is necessary to secure a vacant space for this operation in the surroundings. If a vacant space is provided, there is a problem that fraudulent acts such as inserting a fraudulent tool into the pachinko machine 10 by using the empty space are likely to be performed. On the other hand, according to the configuration of the first hooking device 70A, it is not necessary to provide such an empty space in the surroundings, which is advantageous from the viewpoint of fraud prevention.

(Action according to the first embodiment)
The pachinko machine 10 is configured by attaching a game board 30 having a game area on which a game ball flows down to the inner frame 12 of the game machine body from the front, and the game machine body, that is, the inner frame 12 is attached. The closing position that prevents the game board 30 from being detached by being held in a position that restricts the front-rear position of the front surface of the game board 30 when it is in the position, and the front surface of the game board 30 when it is in the mounting position. The movable hook 72 of the first hooking device 70A and the displacement of the movable hook 72, which are movable parts that can be displaced from the position of 1 and the open position where the gaming board 30 can be attached and detached. Regardless of the configuration, the pusher 73 of the first hooking device 70A, which is a pressing portion that is arranged at a certain front-rear position on the rear side of the game board 30 and presses the game board 30 forward, is provided. There is.

According to the above configuration, the game board 30 can be easily moved in and out of the mounting position by displacing the movable hook 72 in the open position, while the game board 30 can be easily moved in and out by displacing the movable hook 72 in the closed position. It can be fixed at the mounting position, and therefore the game board 30 can be easily attached and detached by the displacement of the movable hook 72.

Further, since the pusher 73 is arranged at a fixed front-rear position regardless of the displacement of the movable hook 72, it is less likely to interfere with the attachment / detachment of the game board 30. At this time, if, for example, as in the reference hooking device 89, the pressing portion (pusher 91) moves forward as the movable portion (movable hook 90) is displaced to the open position, the game is played. Since the space for inserting and removing the board 30 does not expand and the pressing portion (pusher 91) is easily stuck when moving the game board 30 in and out, it is difficult to move the game board 30 in and out, and the game board 30 is easily scratched. There is also the problem. On the other hand, according to the configuration of the pachinko machine 10, even if the movable hook 72 is displaced to the open position, the pusher 73 does not move forward and stays in a certain front-rear position. The space for entering and exiting the game board 30 will be greatly expanded, and the pusher 73 will not be easily attached when the game board 30 is moved in and out. It is also.

Further, the game board 30 arranged at the mounting position is restricted in the front-rear position from the front by the movable hook 72 displaced to the closing position, and is pressed forward by the pusher 73, so that the front surface of the game board 30 is closed. It is pressed against the movable hook 72 at the position and is held at a predetermined front-rear position. Therefore, even if the plate thickness of the game board 30 varies, the front surface of the game board 30 is surely and stably held at a predetermined front-rear position without being affected by the variation.

Further, since the lock member 84, which is an operation unit that can operate without touching the front surface of the game board 30 to displace the movable hook 72, is further provided, the movable hook 72 can be opened by operating the lock member 84. Or it can be easily displaced to the closed position, and therefore the game board 30 can be attached and detached more easily.

At this time, since the lock member 84, which is an operation unit, can be operated without contacting the front surface of the game board 30, the movable hook 72 is displaced by operating the lock member 84 to move the lock member 84 to the front surface of the game board 30. The game board 30 can be attached and detached without touching the game board 30, and therefore the front surface of the game board 30 can be kept in good shape without being scratched or soiled.

Further, since the movable hook 72 is configured to be able to shift to the closed position and the open position by rotating, the damage to the surface of the game board 30 (particularly the damage due to friction) is further reduced. ing.

Further, since the movable hook 72 and the lock member 84 are configured to move in the front-rear direction of the pachinko machine 10 to operate, the area required for the operation can be expanded outward along the board surface direction of the game board 30. There is no such thing. Therefore, it is not necessary to secure an empty space for operation. That is, it is possible to avoid providing an extra space that is easily used for fraudulent activities, which is a desirable configuration from the viewpoint of fraud prevention.

Further, since the movable hook 72 and the pusher 73, which are the portions that come into contact with the game board 30, are made of resin, the damage to the game board 30 is further reduced.

Further, since the movable hook 72 and the pusher 73, together with the lock member 84, are mounted on the base 71 to form the first hooking device 70A, the first hooking device 70A is attached to the inner frame 12. As a result, the movable hook 72 and the pusher 73 can be easily arranged on the inner frame 12 at one time.

Further, the first hooking device 70A is basically a resin as a whole (that is, except for the first and second rotating shafts 81, 85, the first and second torsion coil springs 83, 86, and the E-shaped retaining ring). Because it is composed of, it is a lightweight and inexpensive configuration.

Further, the pachinko machine 10 is configured by attaching a game board 30 having a game area on which a game ball flows down to the inner frame 12 of the game machine body from the front, and the game machine body, that is, the inner frame 12 , The closing position that holds the game board 30 from the front when it is in the mounting position and prevents the game board 30 from being detached, and the position that is separated from the front position of the game board 30 when it is in the mounting position. The movable hook 72 of the first hooking device 70A, which is a movable part that can be displaced between the open position where the game board 30 can be attached and detached, and the movable hook 72 of the first hooking device 70A operate without contacting the front surface of the game board 30. It is configured to include a lock member 84 of the first hooking device 70A, which is an operation unit that can displace the movable hook 72.

According to the above configuration, the game board 30 can be easily moved in and out of the mounting position by operating the lock member 84, which is an operation unit, to displace the movable hook 72 in the open position, while the movable hook 72 is in the closed position. The game board 30 can be easily fixed to the mounting position by displacing the game board 30, and therefore the game board 30 can be easily attached and detached by the displacement of the movable hook 72.

At this time, since the lock member 84 can be operated without touching the front surface of the game board 30, by operating the lock member 84 to displace the movable hook 72, the lock member 84 can be operated without touching the front surface of the game board 30. The game board 30 can be attached and detached, and therefore the front surface of the game board 30 can be kept in good shape without being scratched or soiled.

Further, since the movable hook 72 is configured to be able to shift to the closed position and the open position by rotating, damage to the surface of the game board 30 due to the shift of the movable hook 72 (particularly damage due to friction) is caused. Less.

Further, since the movable hook 72 and the lock member 84 are configured to move in the front-rear direction of the pachinko machine 10 to operate, the area required for the operation can be expanded outward along the board surface direction of the game board 30. There is no such thing. Therefore, it is not necessary to secure an empty space for operation. That is, it is possible to avoid providing an extra space that is easily used for fraudulent activities, which is a desirable configuration from the viewpoint of fraud prevention.

Further, since the movable hook 72, which is a portion that comes into contact with the game board 30, is made of resin, the damage to the game board 30 is further reduced.

Further, since the movable hook 72 and the lock member 84 are mounted on the base 71 and configured as the first hooking device 70A, by attaching the first hooking device 70A to the inner frame 12, the movable hook 72 is attached. The 72 and the lock member 84 can be easily arranged on the inner frame 12 at one time.

Further, the first hooking device 70A is basically a resin as a whole (that is, except for the first and second rotating shafts 81, 85, the first and second torsion coil springs 83, 86, and the E-shaped retaining ring). Because it is composed of, it is a lightweight and inexpensive configuration.

2. Second Embodiment In the first embodiment, instead of the first hooking device 70A, for example, the hooking device according to the second embodiment as shown in FIGS. 31 to 39 (hereinafter, “second hooking device””. (Also referred to as) 70B may be used. The second hooking device 70B shown in the figure has a basic configuration in which a movable hook 93 and a pusher 94 are mounted on a base 92. The base 92, the movable hook 93, and the pusher 94 are members molded using the same resin.

The substrate 92 is composed of an outer body 921 shown in FIGS. 40 and 41 and an inner body 922 shown in FIGS. 42 and 43. As shown in FIGS. 40 and 41, the outer body 921 is from one end edge (upper end edge in FIG. 40) to one side (rear surface side in FIG. 40) of a rectangular flat plate-shaped first piece 92B having a little thickness. ), A rectangular flat plate-shaped second piece 92M having the same thickness extends, and further, from the extending end edge of the second piece 92M, the side opposite to the first piece 92B side (upper side in FIG. 40). A rectangular flat plate-shaped third piece 92T, which also has a slight thickness, extends perpendicularly to, and as a whole, has a three-dimensional shape having a side shape that is bent at two right angles in a substantially zigzag shape. The first piece 92B, the second piece 92M, and the third piece 92T are each formed into a rectangular parallelepiped shape having a slightly small thickness in one direction, in which three or four sides are closed by a plate-like wall, and are continuous with each other. The overall shape as described above is formed, the second piece 92M side surface portion (left front side surface portion in FIG. 41) and the tip surface portion (lower surface portion in FIG. 41) in the first piece 92B, and the first piece 92B side surface in the second piece 92M. The portion (lower surface portion in FIG. 41), the third piece 92T side end face portion (left front side end surface portion in FIG. 41), and the second piece 92M side and the opposite side surface portion (left front side surface portion in FIG. 41) in the third piece 92T. Is also fully open. That is, in the outer body 921, from the tip surface portion of the first piece 92B to the side surface portion of the third piece 92T opposite to the second piece 92M side (left front side surface portion in FIG. 41), while bending at a right angle in a substantially zigzag shape in the side view. The four sides in a row are completely open as a whole.

On the wall on the third piece 92T side (upper side wall in FIGS. 40 and 41) in the thickness direction of the second piece 92M, from the central portion at the boundary with the first piece 92B, inward along the second piece 92M. A hook insertion opening 92H that extends in a rectangular shape (to the vicinity of the center of the wall) is bored. Further, on the wall on the side of the first piece 92B in the thickness direction of the third piece 92T (front side wall in FIG. 40, rear side wall in FIG. 41), from the central portion at the boundary with the second piece 92M, the third piece 92T The wall on the third piece 92T side in the thickness direction of the second piece 92M, that is, the hook insertion opening 92H described above is formed while extending inward (to a position slightly beyond the center of the wall) in a rectangular shape. On the wall, from the central part at the boundary with the third piece 92T, it spreads inward along the second piece 92M in a slightly shallow rectangular shape (slit shape), and as a whole, the second piece 92M and the third piece from the boundary. A pusher insertion opening 92P is bored along the directions of both pieces of the 92T so as to form a substantially L-shape in the side view, which is bent at a right angle at the boundary and spreads while communicating with the same width. The widths of the hook insertion opening 92H and the pusher insertion opening 92P (dimensions along the direction parallel to the boundary between the first piece 92B, the second piece 92M, and the third piece 92T) are the same, and the entire outer body 921 is formed. The width is about 50% of the width of.

From the inner side surface of the two continuous walls on which the hook insertion opening 92H and the pusher insertion opening 92P are formed, the side surface similar to the side surface view substantially zigzag-like side surface wall in the outer body 921 and slightly smaller than the side surface wall. The inner rib 92R having a shape extends vertically. As shown in FIG. 41, the inner rib 92R is located slightly inward from one protruding corner of the tip inside the first piece 92B (lower right corner in FIG. 41) (position closer to the center of the first piece 92B). ) To a position slightly inward (a position closer to the center of the third piece 92T) from one protruding corner of the tip inside the third piece 92T (upper right corner in FIG. 41), one side surface of the outer body 921 (FIG. In 41, it extends parallel to the right side surface) with a distance from the one side surface, and then bends at a right angle along the tip surface (upper end surface in FIG. 41) of the third piece 92T and extends to the other side. Further, it extends from the tip to a position slightly inward (a position closer to the center of the first piece 92B) from the other protruding corner (lower left corner in FIG. 41) of the tip inside the first piece 92B. As a whole, the inner rib 92R has dimensions that are slightly smaller in both the extension height and the total length than the side walls of the outer body 921 and the tip wall on the third piece 92T side, and has a substantially U-shaped back view. Extend while bending at a right angle at a point, and pass through both edges of the hook insertion opening 92H and the pusher insertion opening 92P (that is, the width within the outer body 921 with the same width as the hook insertion opening 92H and the pusher insertion opening 92P). It is a rib that extends (to the center of the direction). Further, at a plurality of locations on the inner side surface of both side pieces of the inner rib 92R and at the center of the inner side surface of the central piece, the thickness of the inner rib 92R in the extending height direction (that is, the thickness of the first piece 92B to the third piece 92T). Sliding ribs 92F having a semicircular cross section are formed at intervals along the direction or the direction in which the first piece 92B and the third piece 92T extend; in FIG. 41, the direction extending from the lower left to the upper right). The sliding rib 92F reduces the contact area of the pusher 94, which will be described later, with the outer surface to reduce the frictional force. Further, the inner rib 92R is provided at two bent portions (corner portions) of the inner rib 92R and at both ends of the inner rib 92R (both ends located near the lower right end and the lower left end of the first piece 92B). A screw-in portion 92C extending in a cylindrical shape in the extending height direction and having a screw hole in the center thereof is integrally formed with the inner rib 92R.

The central piece of the inner rib 92R (horizontal piece forming the upper end surface in FIG. 41) is slightly closer to the tip side (upper side in FIG. 41) than the tip edge (upper edge in FIGS. 40 and 41) of the pusher insertion opening 92P. ) Is formed. In other words, the pusher is inserted so that the side wall of the second piece 92M (left front side wall in FIG. 40) in the third piece 92T extends slightly inward (lower side in FIG. 40) from the central piece of the inner rib 92R. The position of the tip edge of the opening 92P is set. As a result, the restricting wall portion 92G (see FIG. 40) that restricts the forward movement of the pusher 94, which will be described later, is provided so as to cover the substantially U-shaped tip portion of the inner rib 92R from the second piece 92M side. It is formed.

As shown in FIGS. 42 and 43, the inner body 922 has a three-dimensional outer shape similar to the outer body 921 and having dimensions that fit exactly inside the outer body 921, and the outer body 921 has a three-dimensional outer shape. It is configured to have a first piece 95B, a second piece 95M, and a third piece 95T corresponding to the first piece 92B, the second piece 92M, and the third piece 92T, respectively. In the inner body 922, from the side surface portion of the first piece 95B opposite to the second piece 95M side (left front side surface portion in FIG. 42) to the second piece 95M side surface portion of the third piece 95T (left front side surface portion in FIG. 42). , The three surface portions that are connected while bending at right angles in a substantially zigzag shape are completely opened, and the other seven surface portions are completely closed except for the screw insertion hole 95C and the end opening 95P, which will be described later. ..

As shown in FIG. 42, a first spring boss 95L having a round bar shape and a hemispherical tip is projected from the center of the inner surface of the tip surface wall (lower end surface wall in FIG. 42) in the first piece 95B. ing. On both sides of the first spring boss 95L, guide walls 95G having a height slightly larger than the length of the leg portion 93L are provided at intervals slightly larger than the width of the leg portion 93L of the movable hook 93 described later. , Each of which extends parallel to both side surfaces of the first piece 95B from the inner surface of the tip surface wall of the first piece 95B, and the extending end edge forms a substantially L-shaped plane shape and extends so as to bend at right angles to both sides. Therefore, they abut against the side walls of both sides of the first piece 95B and the side walls of the second piece 95M and are integrally continuous. The ridge angle portion of the bent portion of the guide wall 95G is formed in a curved surface shape.

The outer surface of the central piece of the leg portion 93L is formed so as to be positioned on the same surface as the extending end edge of the peripheral wall-shaped portion and to be continuous. In other words, the engaging hole 93P forming surface on the inner inner wall of the main body 93B is formed so as to be slightly recessed inward from the extending end edge of the peripheral wall-shaped portion. As a result, both ends of the peripheral wall-shaped portion are hooking portions 93E protruding from the engaging hole 93P forming surface on the inner inner wall of the main body portion 93B.

As shown in FIGS. 46 and 47, the pusher 94 is from one end edge (upper right edge in FIG. 46) to one side (upper surface side in FIG. 46) of a rectangular flat plate-shaped first piece 94B having a little thickness. ), A rectangular flat plate-shaped second piece 94T, which also has a little thickness, extends longer than the first piece 94B, and as a whole, has a side shape that is bent at a right angle at one point in a substantially L shape. It is a hollow solid with. As shown in FIG. 47, the surface of the pusher 94 opposite to the extending side of the first piece 94B (the left front surface in FIG. 47) is open, and the other seven surfaces are formed so as to be completely closed. .. Further, each of the ridge corner portions formed on the outside of these closed seven surface portions is formed so as to have a corner drop.

As shown in FIG. 46, on the tip surface (left front side surface in FIG. 46) of the first piece 94B, a slightly thick rectangular flat plate-shaped engaging piece 94P corresponding to the engaging hole 93P in the movable hook 93 described above. Is projected. The engaging piece 94P is formed so that each ridge angle portion is angled and the tip surface is a slope whose protruding height gradually increases from the second piece 94T side side (upper side in FIG. 46) to the opposite side thereof.

Further, sliding ribs 94F are formed at both ends in the width direction on the side surface of the second piece 94T (upper side surface in FIG. 46) of the first piece 94B along the extending direction of the first piece 94B. .. The sliding rib 94F has a semicircular cross section, and the semicircular ridge angle portion at the tip (left end in FIG. 46) is formed so as to drop. On the other hand, the region on the tip surface (upper end surface in FIG. 46) of the second piece 94T opposite to the first piece 94B side (right rear side region in FIG. 46) slightly protrudes from the region on the first piece 94B side. It is formed in a stepped shape, whereby the hooking protrusion 94E is formed. The protruding corners at both ends of the hook protruding portion 94E in the width direction are formed so as to fall off in a curved surface shape.

As shown in FIG. 47, a spring receiving portion 94R extending cylindrically along the extending direction of the first piece 94B (or the thickness direction of the second piece 94T) is provided substantially in the center inside the second piece 94T. It is formed integrally. Ribs are formed between the spring receiving portion 94R and both side walls of the second piece 94T, and the spring receiving portion 94R and the tip edge of the rib are integrally formed so as to be integrally continuous. The first piece 94B is molded so as to come to the position of the surface opposite to the extending side (left front side surface in FIG. 47).

As shown in FIG. 39, the movable hook 93 is the first piece of the outer body 921 of the base 92 so that the engagement hole 93P forming side end (upper end in FIG. 39) is inserted into the hook insertion opening 92H from the inside. It is fitted inside the 92B. At this time, the movable hook 93 is arranged so that the engagement hole 93P forming surface (left front side surface in FIG. 39) faces the third piece 92T side of the outer body 921 of the base 92. On the other hand, the pusher 94 puts the first piece 94B and the second piece 94T on the inner rib 92R of the outer body 921 as a posture corresponding to the second piece 92M and the third piece 92T in the outer body 921 of the base 92, respectively. It is fitted into the inside of the inner rib 92R in the outer body 921 from the open side, that is, the side opposite to the pusher insertion opening 92P forming side.

The inner body 922 is fitted to the outer body 921 of the base 92 with the movable hook 93 and the pusher 94 housed therein as described above. At this time, the inner body 922 is fitted inside the outer body 921 so that the open side surfaces of the outer body 921 and the inner body 922 face each other. At this time, as shown in FIG. 38, the first compression coil spring 96 is inserted into the leg portion 93L of the movable hook 93 from one end, and the other end is inserted into the first spring boss 95L of the inner body 922 of the base 92. It is fitted and restrained. As a result, as shown by arrow A18 in FIG. 38, the movable hook 93 is urged in the direction in which the end on the forming side of the engaging hole 93P is projected from the hook insertion opening 92H (upward in FIG. 38). On the other hand, the second compression coil spring 97 is inserted into the spring receiving portion 94R of the pusher 94 from one end, and the other end is fitted and restrained by the second spring boss 95H of the inner body 922 of the base 92. As a result, as shown by arrow A19 in FIG. 38, the pusher 94 in the direction in which the side surface portion of the first piece 94B (left front side surface in FIG. 38) in the second piece 94T protrudes from the pusher insertion opening 92P (lower left direction in FIG. 38). Is urged. In this state, the outer body 921 and the inner body 922 of the base 92 are fixed by screwing and fastening the screws into the screwing portion 92C of the outer body 921 through the screw insertion hole 95C of the inner body 922. As a result, all 10 surfaces of the substrate 92 are closed, and the second hooking device 70B shown in FIG. 31 is obtained.

As shown in an exemplary manner in FIG. 48, the second hooking device 70B is in a position in which the tip of the movable hook 93 is directed to a position where one side edge (right edge) of the game board 30 comes, and is an inner body of the base 92. Similar to the case of the first hooking device 70A described above, the outer surface (right rear side surface in FIG. 48) opposite to the second piece 95M side of the third piece 95T in 922 is overlapped with the front surface of the inner frame 12. It is placed and fixed in two places above and below. At this time, the method of fixing the second hooking device 70B to the inner frame 12 is omitted, but for example, an appropriate fixing means such as an adhesive may be used, or the above-mentioned first hooking device 70A may be used. As in the case, an appropriate screw insertion piece may be formed on the substrate 92 and fixed with screws. Further, a space is formed between the first piece 92B of the outer body 921 or the first piece 95B of the inner body 922 and the front surface of the inner frame 12 in the second hooking device 70B in the fixed arrangement state (first). The pieces 92B and 95B are floating forward), but the space may be filled with an appropriate member, or the base 92 of the second hooking device 70B may have an outer shape that includes this space in advance. That is, it may be formed so that it has a rectangular parallelepiped shape including this space as a whole and has an outer shape in which only the first piece 92T of the outer body 921 and the third piece 95T of the inner body 922 extend. omit). According to this, the second hooking device 70B can be more stably fixed to the front surface of the inner frame 12.

At this time, the fixing hook 87 is arranged and fixed on the front surface of the inner frame 12 at a position corresponding to substantially the center in the height direction on the left edge of the game board 30, as in the first embodiment described above.

Hereinafter, the procedure for attaching the game board 30 using the second hooking device 70B will be sequentially described.
(A) Before the mounting work, normally, as shown in FIGS. 49 and 50, the movable hook 93 of the second hooking device 70B is housed in the base 92 and set to the open position. If the movable hook 93 is projected from the hook insertion opening 92H, it becomes more susceptible to contact from the surroundings and is more likely to be damaged. Therefore, the movable hook 93 is moved to the open position in this way and inside the base 92. It is desirable to store (retract) in.

As shown by a chain line in FIG. 50, the position where the movable hook 93 protrudes from the hook insertion opening 92H is the closing position. As shown by the arrow A20 in FIG. 50, the movable hook 93 in the closed position is placed in the base 92 so as to oppose the urging force of the first compression coil spring 96, that is, to compress the first compression coil spring 96. When pushed into, the cam surface 93C of the movable hook 93 opposes the urging force of the second compression coil spring 97, that is, compresses the second compression coil spring 97, and pushes the engaging piece 94P of the pusher 94 backward, that is, inside. The movable hook 93 enters the base 92 while pushing it back toward the frame 12. When the tip surface of the movable hook 93 is retracted to a position where it is exactly flush with the hook insertion opening 92H forming surface of the base 92, that is, an open position, the engaging hole 93P of the movable hook 93 reaches the position of the engaging piece 94P of the pusher 94. Then, the engaging piece 94P is fitted into the engaging hole 93P by the urging force of the second compression coil spring 97 and engaged. Once the engaging piece 94P is fitted into the engaging hole 93P, it is held in this engaged state by the urging force of the second compression coil spring 97. That is, by the urging force of the second compression coil spring 97, the engaging piece 94P is fitted into the engaging hole 93P and held in an engaged state, whereby the movable hook 93 is completely housed in the base 92 and opened. Locked in position.

At the open position, the side surface portion of the first piece 94B (lower side surface portion in FIG. 50) of the second piece 94T of the pusher 94 is inserted into the pusher at the third piece 92T of the base 92 by the urging force of the second compression coil spring 97. It is held at a position slightly protruding forward (downward in FIG. 50) from the opening 92P forming surface. At this time, the base end portion of the second piece 94T of the pusher 94 (near the bent portion in the pusher 94) is the front end edge of the pusher insertion opening 92P (the pusher insertion opening 92P extending to the second piece 92M of the base 92). The forward movement is restricted by the extending end edge), while the tip of the second piece 94T of the pusher 94 is hooked by the hooking protrusion 94E to the regulating wall portion 92G of the base 92. Forward movement is restricted.

(B) At the time of mounting work, as shown in FIG. 51, the gaming board 30 is tilted so that the right side is farther from the pachinko machine 10 in the same manner as in the first embodiment described above. The left end edge is inserted into the fixing hook 87 from the front right and hooked inside the front piece 87F.

(C) Then, in the same manner as in the first embodiment described above, as shown by the arrow A21 in FIG. 51, the game board 30 is closed with the door closed around the hooking position of the left end edge described above (c). In FIG. 51, it is rotated (counterclockwise) to fit the right end portion of the second hooking device 70B to a position where it abuts on the pusher 94, as shown in FIG. 52.

At this time, the left side portion of the game board 30 is positioned and held by the fixed hook 87 as in the above-described first embodiment.

On the other hand, in the second hooking device 70B, since the movable hook 93 is set in the open position as in the case of the first hooking device 70A described above, the right end portion of the game board 30 can be easily fitted. be able to. In particular, the pusher 94 is arranged at a certain rear (back) position along the front surface of the inner frame 12 regardless of the movement (displacement) of the movable hook 93, and is slightly moved with the movement of the movable hook 93. While the movable hook 93 in the open position deviates outside the rotation trajectory of the game board 30, the above-mentioned reference hooking device 89 is substantially immobile only by moving back and forth. It is the same as the case of the first hooking device 70A described above that the game board 30 can be attached and detached more easily and safely than in the case of.

(D) As shown by arrow A22 in FIG. 52, when the right end portion of the game board 30 is pushed further rearward from the position where it abuts on the pusher 94 of the second hooking device 70B, FIGS. 53 and 54 show. As shown, the movable hook 93 of the second hooking device 70B protrudes from the hook insertion opening 92H and returns to the closing position.

At this time, as shown in FIG. 54, when the right end portion of the game board 30 is pushed backward and the pusher 94 is also pushed backward as described above, the pusher 94 is fitted into the engaging hole 93P of the movable hook 93. The engaging piece 94P of the pusher 94 that was engaged with the pusher 94 escapes rearward from the engaging hole 93P to release the engaged state, and the movable hook 93 is released from the hook insertion opening 92H by the urging force of the first compression coil spring 96. It is pushed out in the protruding direction. The movable hook 93 is restricted from moving further outward by the hooking portion 93E hooking from the inside to the peripheral wall of the hook insertion opening 92H in the second piece 92M of the base 92 (not shown). , It is held at this hooking position by the urging force of the first compression coil spring 96.

(E) With the movable hook 93 protruding from the hook insertion opening 92H and in the closed position as described above, when the force for pushing the right end of the game board 30 backward is removed (released), the second The basting force of the compression coil spring 97 causes the pusher 94 to push the right end of the game board 30 forward and press it against the movable hook 93 from behind, whereby the front surface of the right end of the game board 30 is on the inner surface of the movable hook 93. Held in position. According to this configuration, as in the case of using the first hooking device 70A described above, the elasticity of the pusher 94 allows the front surface of the game board 30 to be accurately aligned with a predetermined front-rear position while absorbing variations in plate thickness. It can be installed.

When removing the game board 30, the movable hook 93 in the closed position is pushed into the base 92 to be in the open position again. At this time, when the game board 30 is pressed against the movable hook 93 by the pusher 94 from behind, it is difficult to move the movable hook 93 due to friction with the game board 30, and the front surface of the game board 30 is easily scratched. When the movable hook 93 is moved while pressing the right end of the game board 30 backward against the urging force of the second compression coil spring 97, the movable hook 93 can be easily moved without damaging the game board 30. Can be moved.

According to the above mounting step, as in the first embodiment described above, even if the plate thickness of the game board 30 varies, the left and right side ends of the game board 30 are fixed hooks 87 and the second hook, respectively. The stop device 70B can be attached so that the front and rear positions of the front surface are accurately aligned with a predetermined position. In particular, the use of the second stop device 70B has the following advantages.

In the second hooking device 70B, the movable hook 93 in the closed position can be easily set to the open position, and the engaging piece 94P of the pusher 94 is the second compression coil spring 97 in the open position. The movable hook 93 is easily and surely locked to the open position by being fitted into and engaged with the engaging hole 93P of the movable hook 93 by the urging force. At this time, the second compression coil spring 97 urges the pusher 94 mainly for the purpose of pressing the game board 30 forward, and the engaging piece 94P of the pusher 94 can be moved by using this urging force. Since the hook 93 is fitted into the engaging hole 93P for engagement, the number of parts is small and the mechanism is efficiently configured and simplified.

Further, when the movable hook 93 in the open position is set to the closed position, the movable hook 93 can be moved by pushing the pusher 94 at the right end of the game board 30 while bringing the game board 30 to the mounting position. The engagement state of the engagement piece 94P with the engagement hole 93P is released, and the movable hook 93 is pushed out by the urging force of the first compression coil spring 96 to automatically return to the closed position. That is, by pushing the right end of the game board 30 into the mounting position, the movable hook 93 can be automatically set to the closed position without any other operation, and therefore the work becomes easier. There is.

Further, since the movable hook 93 and the pusher 94 that come into contact with the game board 30 are made of resin, the damage to the game board 30 is further reduced, and in addition, the base 72 is also included in the second hooking device. Since the entire 70B is basically made of resin, the second hooking device 70B is made lightweight and inexpensive. Furthermore, in the movable hook 93, the corners inside the tip portion that easily contacts the game board 30 are molded into a shape with a corner drop, and the other ridge corner portions including the pusher 94 are also molded into a shape with a corner drop. Therefore, the damage to the game board 30 is reduced.

(Action according to the second embodiment)
The pachinko machine 10 is configured by attaching a game board 30 having a game area on which a game ball flows down to the inner frame 12 of the game machine body from the front, and the game machine body, that is, the inner frame 12 is attached. The closing position that prevents the game board 30 from being detached by being held in a position that restricts the front-rear position of the front surface of the game board 30 when it is in the position, and the front surface of the game board 30 when it is in the mounting position. The movable hook 93 of the second hooking device 70B and the displacement of the movable hook 93, which are movable parts that can be displaced from the position of 2 and the open position where the gaming board 30 can be attached and detached. Regardless of the configuration, the pusher 94 of the second hooking device 70B, which is arranged at a certain front-rear position on the rear side of the game board 30 and is a pressing portion for pressing the game board 30 forward, is provided. There is.

According to the above configuration, the game board 30 can be easily moved in and out of the mounting position by displacing the movable hook 93 in the open position, while the game board 30 can be easily moved in and out by displacing the movable hook 93 in the closed position. It can be fixed at the mounting position, and therefore the game board 30 can be easily attached and detached by the displacement of the movable hook 93.

Further, since the pusher 94 is arranged at a fixed front-rear position regardless of the displacement of the movable hook 93, it is less likely to interfere with the attachment / detachment of the game board 30. At this time, if, for example, as in the reference hooking device 89, the pressing portion (pusher 91) moves forward as the movable portion (movable hook 90) is displaced to the open position, the game is played. Since the space for inserting and removing the board 30 does not expand and the pressing portion (pusher 91) is easily stuck when moving the game board 30 in and out, it is difficult to move the game board 30 in and out, and the game board 30 is easily scratched. There is also the problem. On the other hand, according to the configuration of the pachinko machine 10, even if the movable hook 93 is displaced to the open position, the pusher 94 does not move forward and stays in a certain front-rear position. The space for entering and exiting the game board 30 will be greatly expanded, and the pusher 94 will not be easily attached when the game board 30 is moved in and out. It is also.

Further, the game board 30 arranged at the mounting position is restricted in the front-rear position from the front by the movable hook 93 displaced to the closing position, and is pressed forward by the pusher 94, so that the front surface of the game board 30 is closed. It is pressed against the movable hook 93 at the position and is held at a predetermined front-rear position. Therefore, even if the plate thickness of the game board 30 varies, the front surface of the game board 30 is surely and stably held at a predetermined front-rear position without being affected by the variation.

Further, an engaging hole 93P and an engaging piece 94P are provided as an engaging structure in which the movable hook 93 and the pusher 94 in the open position are engaged with each other, and the engaging hole 93P and the engaging piece 94P are the pushers. Since the 94 engages with each other by using the pressing force that presses the game board 30 forward, that is, the urging force of the second compression coil spring 97, the number of parts is small and the mechanism is efficiently configured. It is simplified.

Further, the movable hook 93 is urged by the first compression coil spring 96 so as to move from the open position to the closed position, and by pressing the pusher 94 rearward, the above-mentioned engaging hole 93P and the engaging piece 94P are brought into contact with each other. Since the engaged state is released and the movable hook 93 automatically moves to the closed position, the movable hook 93 can be automatically set to the closed position simply by pushing the game board 30 into the mounting position. Therefore, the operation is simple and the mounting work of the game board 30 can be easily performed.

Further, since the movable hook 93 and the pusher 94, which are the portions that come into contact with the game board 30, are made of resin, the damage to the game board 30 is further reduced.

Further, since the movable hook 93 and the pusher 94 are mounted on the base 92 and configured as the second hooking device 70B, the movable hook 93 can be attached to the inner frame 12 by attaching the second hooking device 70B. And the pusher 94 can be easily arranged on the inner frame 12 at a time.

Further, since the second hooking device 70B is basically made of resin as a whole (that is, excluding the first and second compression coil springs 96 and 97 and the screws), it is lightweight and inexpensive. There is.

(Change mode)
Various changes can be made to the pachinko machine 10 according to the first and second embodiments, for example, as listed below. In the following description and drawings, the same members or parts as those in the first and second embodiments are designated by the same reference numerals, and the description thereof will be basically omitted.

(1) In the first and second embodiments, the first hooking device 70A and the second hooking device 70B are basically composed of resin as a whole, but a part or all of the hooking device is used. For example, it may be made of metal or the like. For example, it is possible to configure most of the hooking device to be made of metal and to form a coating layer made of resin, rubber, etc. on the part that comes into contact with the game board, for example, the inner surface of the movable hook or pusher. Is.

(2) In the first embodiment, the movable hook 72 is moved to the closed position and the open position by the operation of pushing and pulling out the lock member 84 in the first hooking device 70A. As the configuration of the above, for example, a lever or the like that operates by rotation may be arranged at a position different from the movable hook, and the operation can be easily performed by this. However, from the viewpoint of preventing the operation space from expanding to the surroundings as much as possible, it is desirable to have a configuration in which the gaming machine linearly moves (slides) in the front-rear direction like the lock member 84 in the first embodiment. ..

(3) In the first embodiment, the first torsion coil spring 83 and the second torsion coil spring 86 are arranged as means for urging the movable hook 72 and the pusher 73 in the first hooking device 70A, respectively. For example, as shown in an exemplary manner in FIG. 55, the movable hook 62 and the pusher 63 may be urged by the same urging means. The third hooking device 70C shown in the figure has the same configuration as the first hooking device 70A except that a leaf spring 64 is arranged in place of the first torsion coil spring 83 and the second torsion coil spring 86. It has become. The leaf spring 64 extends long in a strip shape and is bent at an intermediate portion so as to have a substantially “he” shape in the side view. It is arranged and fixed at a position between the circular tip and the pusher 63. At the position where the intermediate portion of the leaf spring 64 comes on the inner surface of the base 65 of the third hooking device 70C, the intermediate portion of the leaf spring 64 has a substantially "he" -shaped cross section and is inward. Two protruding ribs 65R are formed in parallel, and an intermediate portion of the leaf spring 64 is fixed so as to be sandwiched between both ribs 65R. The one piece 64D extending from the middle portion of the leaf spring 64 to one side passes through a slit (not shown) formed on the peripheral surface of the tip end portion of the rotating cylinder portion 62D in the movable hook 62 into the inside of the rotating cylinder portion 62D. The extension is extended, and the extension end presses the rotating body portion 62D from the inside, and as shown by the arrow A23 in FIG. 55, the movable hook 62 is attached to the open position side (counterclockwise in FIG. 55). It is gaining momentum. The other piece 64P extending from the intermediate portion of the leaf spring 64 to the other extends into the inside of the pusher 63 through a slit (not shown) formed in the front surface of the recessed portion in the pusher 63, and the extending end thereof extends to the inside of the pusher 63. The pusher 63 is pressed from the inside, and as shown by the arrow A24 in FIG. 55, the pusher 63 is urged so that it can be pressed forward, that is, the game board 30 can be pressed from the back side (clockwise in FIG. 55).

According to the above configuration, the movable hook 62 and the pusher 63 are urged by the leaf spring 64 which is the same urging means, and can function in the same manner as in the case of the first hooking device 70A described above. .. Therefore, the number of parts is reduced and the configuration is simplified.

(4) In the first and second embodiments, the left edge of the game board 30 is fixed hook 87 at one position substantially at the center in the height direction, and the right edge is at two locations near the upper end and the lower end from the first to the first to the lower ends. Although it was fixed by the second hooking devices 70A and 70B, respectively, the arrangement of the fixing means in the first and second embodiments can be variously changed as listed below, for example.

1. 1. The right edge of the game board 30 is fixed at one place substantially in the center in the height direction by the first and second hooking devices 70A and 70B. According to the arrangement of, the first and second hooking devices 70A and 70B to be used can be used as one, so that the number of parts can be reduced, the configuration can be simplified, and the installation time and effort can be reduced. Will be done. However, in order to correctly introduce the game ball ejected from the launching device to the front surface of the game board 30, the accuracy of the front-rear position of the lower end portion of the game board 30 is particularly important, and therefore, from the viewpoint of this position accuracy, As in the arrangement in the first and second embodiments, it is desirable that at least the vicinity of the lower end of the game board 30 is fixed by the first and second hooking devices 70A and 70B, and in this case, the game board. Since it is difficult to stably support 30 only in the vicinity of the lower end, it is desirable that the vicinity of the upper end is also fixed by the first or second hooking devices 70A and 70B.

2. 2. The left edge of the game board 30 is fixed by the first and second hooking devices 70A and 70B at appropriate positions such as one place in the center in the height direction or two places near the upper end and the lower end. Above 2. In the arrangement of, the right edge of the game board 30 is fixed by the fixing hook 87, that is, the arrangement in the first and second embodiments is reversed left and right.

Above 2. Or 3. According to the arrangement of, at least the left side edge of the game board 30 is fixed by the first and second hooking devices 70A and 70B. As described above, the opening / closing axis of the pachinko machine 10 is on the opposite side of the game ball launch handle 18 installation location, that is, on the left side of the pachinko machine 10, so that the first and second hooking devices 70A and 70B are the game board 30. If it is placed on the left side of the machine, even if the front frame is opened, the operation space will be significantly restricted compared to the right side due to the presence of this front frame, and when the pachinko machine 10 is closed, it will be compared to the right side. Since it is difficult for fraudulent tools to enter, it is desirable from the viewpoint of preventing fraudulent operations. However, on the other hand, due to the narrow operation space, it is disadvantageous for the operation of the first and second hooking devices 70A and 70B in attaching and detaching the game board 30, and therefore, from this viewpoint, the first and second hooking devices are disadvantageous. As in the arrangement in the second embodiment, the left edge of the game board 30 may be fixed by a fixing means such as a fixing hook 87 which can be fixed without requiring any operation other than inserting the game board 30. desirable.

4. The first and second embodiments or the above 1. ~ 3. In the arrangement of, at least the base 66 is a game like the fourth hooking device 70D shown in FIG. 56 and the fifth hooking device 70E shown in FIG. 57 instead of the first and second hooking devices 70A and 70B. A hooking device having a structure extending long along the side edge of the board 30 is used.

In the fourth hooking device 70D shown in FIG. 56, the first face plate 67, the second face plate 68, and the fifth face plate 69 of the base 66 correspond to the lengths from the vicinity of the upper end to the vicinity of the lower end on the side edge of the game board 30. The components of the first hooking device 70A other than the first face plate 74, the second face plate 75, and the fifth face plate 78 of the base 71, that is, the base 71, are formed at both upper and lower ends thereof. The third face plate 76, the fourth face plate 77, the movable hook 72, the pusher 73, and the lock member 84 are all arranged. In other words, the fourth hooking device 70D is the first face plate 74 and the second face plate of the base 71 of the first hooking device 70A arranged at two locations near the upper end and the lower end as in the first embodiment. The 75 and the fifth face plate 78 extend long so as to approach each other in the vertical direction, respectively, and are integrally continuous as the first face plate 67, the second face plate 68, and the fifth face plate 69 of the substrate 66, whereby. The two first hooking devices 70A arranged vertically are configured as one fourth hooking device 70D having a base 66 extending vertically as a whole.

The fifth hooking device 70E shown in FIG. 57 corresponds to the length from the vicinity of the upper end to the vicinity of the lower end of the side edge of the game board 30 not only for the base 66 but also for the movable hook 98 in the fourth hooking device 70D. The lock member 84 is formed into a shape that extends vertically long and is arranged substantially in the center in the height direction, so that the lock member 84 is operated between the open position and the closed position.

According to the fourth hooking device 70D to the fifth hooking device 70E, the first and second hooking devices 70A are located at two locations near the upper end and the lower end as in the arrangement in the first and second embodiments. Compared to the case where the 70Bs are arranged, the fourth to fifth hooking devices 70D and 70E themselves are larger, which is disadvantageous in terms of moldability, handleability, storage, etc. The side edges of the board 30 can be supported more stably and more reliably, and the fourth to fifth hooking devices 70D and 70E can be attached at once instead of being mounted up and down separately, which is convenient. Further, since the relative position between the upper and lower parts is fixed in the 4th to 5th hooking devices 70D and 70E, there is no positional deviation between the upper and lower parts, and it is not necessary to position the upper and lower parts separately. Positioning can be performed accurately and easily.

Further, according to the fifth hooking device 70E, since the movable hook 98 also extends long in the vertical direction, the side edge of the game board 30 can be held more stably, and the movable hook 98 of the movable hook 98 can be held more stably. It is convenient because the operation can be done at once instead of moving up and down. In the fifth hooking device 70E, the movable hook 98 extending vertically is operated by the lock member 84 arranged substantially in the center in the height direction. For example, the fourth hooking device 70E is described above. In the stop device 70D, the movable hooks 72 arranged vertically are also configured to be operated all at once by the lock members 84 arranged substantially in the center in the height direction (not shown). However, in this case, it is necessary to provide a member or mechanism for transmitting power between the lock member 84 and the movable hook 72, and therefore, from the viewpoint of the number of parts or the simplicity of the configuration, the fifth hooking device 70E is used. It is desirable to have a proper configuration.

As described above, the fourth hooking device 70D to the fifth hooking device 70E are the first face plates 74 of the base 71 in the pair of the first hooking devices 70A arranged one above the other in the first embodiment. The second face plate 75 and the fifth face plate 78 are extended so as to be in contact with each other so as to be integrally configured as the first face plate 67, the second face plate 68, and the fifth face plate 69 of the base 66. However, in the same manner as this, a part of the substrate in the second hooking device 70B arranged vertically may be formed vertically long to be integrally formed (specific description and illustration are omitted). ).

Furthermore, according to the fourth hooking device 70D to the fifth hooking device 70E, the urging means for urging the movable hooks 72, 98 and the pusher 73 are arranged vertically (not shown). For example, the urging means is provided only at one place such as substantially in the center in the height direction, and the upper and lower movable hooks 72 and the pusher 73 are simultaneously extended by this one urging means, or the entire movable hook 98 extending vertically is extended. The configuration may be such that the urging means is urged, thereby reducing the points of the urging means.

Furthermore, the first and second embodiments or the above 1. ~ 3. When the hooking devices are arranged at a plurality of places as in the arrangement of, the same hooking device may be arranged at a plurality of places, but a plurality of hooking devices different from each other may be arranged at a plurality of places. You may try to do it. For example, on the opening / closing axis side of the pachinko machine 10, that is, on the left side, a hooking device having a configuration in which the required operating space (movable area) is as small as possible is arranged, and on the right side, operability is provided even if the operating space is large. An arrangement such as arranging a hooking device having an advantageous configuration in other aspects such as cost can be mentioned.

(5) In the first and second embodiments, the movable hooks 72, 93, the pushers 73, 94 and the lock member 84 are mounted on the bases 71, 92, and the first and second hooking devices 70A and 70B are mounted. However, for example, even if each part of the movable hook (movable part), pusher (pressing part) and lock member (operating part) is directly arranged on the game machine main body such as the inner frame. Often, this allows the manufacturing process of the hooking device and the substrate as a component to be omitted. However, according to this, since it is necessary to provide a structure for attaching each of the above parts to the gaming machine main body such as the inner frame, the configuration of the gaming machine main body such as the inner frame becomes complicated and relatively. Since the work tends to be complicated if the above-mentioned parts are directly attached to the main body of the gaming machine such as a large inner frame, the above-mentioned parts are once assembled as a hooking device as in the first and second embodiments. If the hooking device is attached to the main body of the gaming machine such as an inner frame, it is easier to obtain a configuration in which the above-mentioned parts are arranged in the main body of the gaming machine.

The present specification discloses the inventions of means A1 to means A9, means B1 to means B, means C1 and means D1 to means D3 listed below.

[Background Technology of Inventions Related to Means A1 to A9 / Problems to be Solved by Inventions]
A game machine such as a pachinko machine is equipped with a game board in which a game area in which the game ball flows down is formed on the front surface, and the game ball can be guided to the game area of the game board to play a game. Is common. In conventional gaming machines, the mainstream structure is to attach the gaming board from the back side of the gaming machine, but there is a problem that it takes time and effort to attach and detach the gaming board, resulting in poor efficiency. Therefore, for example, as disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 6-47157), it has been proposed to have a structure in which a gaming machine is attached from the front side of the gaming machine. In the structure described in Patent Document 1, the game board is arranged from the front side of the game machine, and the hook member is locked from the side to the side edge portion of the game board, so that the game board is placed at the mounting position. It is designed to be fixed. According to this, for example, it is possible to replace the game board from the front side while the game machine is installed in the game hall, so that the game board can be installed in a stable state. The replacement work can be performed and the work is easier, and when the replacement work of the gaming board is performed from the front side of the gaming machine, it is only necessary to open the front frame, so that the replacement work is performed from the back side. There is also the advantage that it takes less time to open the gaming machine.

By the way, especially in the case of a pachinko machine, it is important to accurately match the relative front-rear position of the front surface of the game board with respect to the launcher located below the game board, and if this relative position is displaced, the machine is fired. This causes a problem that the gaming ball fired from the device is not correctly introduced into the gaming area of the gaming board. In the past, as described above, the game board was attached from the back side of the game machine, so the game board was positioned by contacting the game machine body at the front, and therefore the front and rear positions of the front of the game board were positioned at the game machine body. However, it was always constant, and the above-mentioned positional deviation was unlikely to occur. On the other hand, if the structure is such that the game board is attached from the front side of the game machine, the game board is positioned in contact with the game machine body on the back side, so that the thickness of the game board varies, for example. In some cases, there is a problem that the front-rear position of the front surface of the gaming board also varies, causing the above-mentioned positional deviation.

However, according to the above description of Patent Document 1, the locking position by the hook member is set so as to come to a fixed position at a distance of a predetermined thickness of the gaming board from the frame of the gaming machine main body to the front. However, the problem of positional deviation due to the variation in the plate thickness of the gaming board as described above is not taken into consideration. For this reason, for example, if the game board becomes thinner than the predetermined thickness due to variations in the plate thickness of the game board, the game board will rattle back and forth, while if the game board becomes thicker than the predetermined thickness, it will be locked by the hook member. In either case, it is difficult to accurately and stably align the front and rear positions of the front surface of the game board. Therefore, it must be said that the structure described in Patent Document 1 is insufficient in terms of positioning and stability of the game board. In other words, the structure described in Patent Document 1 is a structure in which the game board is attached from the front side of the game machine, so that the game board can be easily attached and detached. Although a new problem of variation in the front position of the game board has arisen, it can be said that this problem has not yet been considered.

The present invention relating to the means A1 to the means A9 has been devised in view of the above problems, and an object of the present invention is to provide a gaming machine excellent in ease of attachment / detachment of a gaming board, positioning accuracy, and stability. do.

Further, since the pressing portion is arranged at a fixed front-rear position regardless of the displacement of the movable portion, it is unlikely to interfere with the attachment / detachment of the game board. At this time, if the pressing portion moves forward as the movable portion is displaced to the open position, the space for entering and exiting the game board does not expand, and when the game board is moved in and out, The pressing portion is easy to stick to. On the other hand, according to the configuration of the means A1, even if the movable portion is displaced to the open position, the pressing portion does not move forward and stays at a certain front-rear position. The space is greatly expanded, and the pressing portion is not easily attached when the game board is moved in and out, so that the game board can be easily moved in and out.

Further, since the game board arranged at the mounting position is restricted from the front by the movable portion displaced to the closing position and pressed forward by the pressing portion, the front surface of the game board is in the closing position. It is pressed against the movable part and held in a predetermined front-rear position. Therefore, even if there is a variation in the plate thickness of the game board, the front surface of the game board is surely and stably held at a predetermined front-rear position without being affected by this.
