Description

The present invention relates to a gaming machine such as a slot machine.

For example, there is a slot machine as a kind of gaming machine. Generally, a slot machine includes a box-shaped housing having an open front surface and a front door pivotally supported on the front side of the housing, and a plurality of reels having a pattern inside the housing. It houses a variable display device, a control device for controlling games, a hopper device for paying out medals, and the like.

Generally, in a game machine such as a slot machine, a front door is provided so as to be openable and closable with respect to a housing from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the clerk cannot open the front door without permission.

Such a locking device includes a cylinder lock operated by using a dedicated key, a hook member provided in the housing so as to be engaged and disengaged from the engaged portion, and an unlocking operation of the cylinder lock by the key. It is known that the hook member is provided with a sliding rod for operating the hook member according to the above (see, for example, Patent Document 1).

Then, in the locked state, the hook member engages with the engaged portion, so that the front door cannot be opened with respect to the housing. On the other hand, by unlocking the cylinder lock with a dedicated key, the hook member is disengaged from the engaged portion via the sliding rod, and the front door can be opened.

[First Embodiment]
Hereinafter, an embodiment when applied to a rotating cylinder type gaming machine, which is a kind of gaming machine, specifically, a slot machine, will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 open, and FIG. 4 is a front view. It is a front view of the slot machine 10 with the door 12 open.

As shown in FIGS. 1 to 4, the slot machine 10 includes a housing 11 as a support member (fixing frame) forming an outer shell thereof. The housing 11 is composed of a top plate 11a, a bottom plate 11b, a back plate 11c, a left side plate 11d and a right side plate 11e formed in the shape of a wooden plate, and the adjacent plates 11a to 11e are fixed by fixing means such as adhesion. As a result, it is formed in a box shape with the front surface open as a whole. In addition to being made of wooden panels, each of the plates 11a to 11e may be made of a synthetic resin panel or a metal panel, or may be made of a synthetic resin material or a metal material to form an integral box. You may. The housing 11 configured as described above is attached by hitting a nail against the so-called island equipment at the time of installation in the game hall.

A front door 12 as a door body is provided on the front side of the housing 11. The front door 12 is attached so as to be openable and closable by a pair of upper and lower hinge mechanisms 25a and 25b provided on the left side plate 11d of the housing 11. As a result, the front door 12 is rotatably supported with respect to the housing 11 about the opening / closing axis extending in the vertical direction connecting the hinge mechanisms 25a and 25b, and the rotation opens or closes the front opening side of the housing 11. It is configured to be able to.

Further, the front door 12 is in a state in which it cannot be opened by the locking device 600 provided on the back side thereof and the receiving metal fitting 800 as a receiving member provided on the housing 11 side. Details of the locking mechanism including the locking device 600 and the receiving metal fitting 800 will be described later.

A game panel 30 for notifying the player of the game state is provided near the center of the front door 12. The game panel 30 is formed so that three vertically long display windows 31L, 31M, and 31R are arranged side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 can be visually recognized through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into one to form a common display window.

As shown in FIGS. 3 and 4, the inside of the housing 11 is divided into upper and lower parts by a partition plate 40, and a reel unit 41 constituting a variable display means is housed in the upper part of the partition plate 40.

The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R as rotating bodies formed in a cylindrical shape (annular shape), respectively. Each reel 42L, 42M, 42R is rotatably supported so that its central axis is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, 42R correspond one-to-one with the display windows 31L, 31M, 31R. .. Therefore, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R, respectively. A belt-shaped belt is wound around the outer peripheral surface of each reel 42L, 42M, 42R, and a large number of symbols as identification information are printed on the outer peripheral surface of the belt at equal intervals. Then, when the reels 42L, 42M, 42R rotate in the forward direction, the surfaces of the reels 42L, 42M, 42R are projected as if they are moving from top to bottom through the display windows 31L, 31M, 31R.

Each of these reels 42L, 42M, 42R is connected to stepping motors 61L, 61M, 61R (see FIG. 6) as driving means, and each reel 42L is driven by driving each stepping motor 61L, 61M, 61R. , 42M, 42R can be rotationally driven individually, that is, independently of each other. Then, as the drive shafts of the stepping motors 61L, 61M, 61R rotate, the reels 42L, 42M, 42R rotate around the drive shafts so as to rotate.

Further, reel index sensors 55L, 55M, 55R (see FIG. 6) are installed in the reel unit 41. In the present embodiment, as the reel index sensors 55L, 55M, 55R, a transmissive photo sensor in which a light emitting element and a light receiving element are held at predetermined intervals is adopted. Then, each reel index sensor 55L, 55M, 55R detects that a sensor cut van (not shown) passes between both elements every time each reel 42L, 42M, 42R makes almost one round, and each time, the main control described later is performed. A detection signal is output to the device 131. Based on this detection signal, the main control device 131 can confirm and correct the rotation position of each reel 42L, 42M, 42R approximately every one round.

For example, in the present embodiment, the stepping motors 61L, 61M, and 61R are set to rotate once by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter). That is, each reel 42L, 42M, 42R is configured to rotate by a rotation amount corresponding to the number of drive signals, such that each reel 42L, 42M, 42R changes by 5 ° with a 7-pulse drive signal. There is. Further, the rotation position of the stepping motors 61L, 61M, 61R, that is, the rotation position of each reel 42L, 42M, 42R is controlled by this drive signal.

On each of the belts of the reels 42L, 42M, and 42R described above, a plurality of symbols, specifically 21 symbols, are drawn in the long side direction (circumferential direction) thereof. Therefore, it takes 24 pulses (= 504 pulses ÷ 21 symbols) to switch from one symbol to the next at a predetermined position. Then, based on the number of pulses from the time when the rotation position of each reel 42L, 42M, 42R is detected, it is possible to recognize which symbol is visible from each display window 31L, 31M, 31R, or arbitrarily. It is possible to control the design so that it can be visually recognized from the display windows 31L, 31M, and 31R.

Of the symbols attached to the reels 42L, 42M, 42R, the number of symbols that can be visually recognized as a whole through the display windows 31L, 31M, 31R is mainly determined by the length of the display windows 31L, 31M, 31R in the vertical direction. Limited to a predetermined number. In this embodiment, there are three reels each. Therefore, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 5 shows a pattern arrangement drawn on a belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each reel 42L, 42M, 42R is provided with 21 symbols in a row. Numbers 1 to 21 are assigned to each reel 42L, 42M, 42R, but this is for convenience of explanation and is not actually attached to the reels 42L, 42M, 42R. .. However, in the following description, the number will be used for description.

As the symbols, there are a "red 7" symbol (for example, the 20th left belt) and a "white 7" symbol (for example, the 19th left belt) as the first special symbol for shifting to the big bonus game. .. In addition, there is a "BAR" symbol (for example, the 14th left belt) as a second special symbol for shifting to the regular bonus game. In addition, there is a "replay" symbol (for example, the eleventh left belt) as a third special symbol for shifting to the replay game. In addition, the "watermelon" symbol (for example, the 9th left belt), the "bell" symbol (for example, the 8th left belt), and the "cherry" symbol (for example, the left) as the small winning combination symbols for which the small winning combination is paid out. There is a fourth belt). As shown in FIG. 5, the number and arrangement order of various symbols are completely different in the belts wound around the reels 42L, 42M, and 42R.

The game panel 30 is provided with a total of five combination lines, three in parallel in the horizontal direction and two in the diagonal direction so as to connect the display windows 31L, 31M, and 31R. Of course, the maximum number of combination lines may be 6 or more, less than 5, and the maximum number of combination lines may be changed according to a predetermined condition. Effective line display units 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R groups corresponding to each of these combination lines. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. The second effective line display unit 33 is notified by lighting or the like when the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (a downward-sloping line and an upward-sloping line) of the combination lines are enabled. Then, when the symbols stop at the activated combination line, that is, the valid line in a predetermined combination, a prize is won, and a predetermined medal payout process, a transfer process to a specific game, and the like are executed.

Here, the number of payouts for each symbol in the case of winning a prize will be described. Regarding small role symbols, if the "watermelon" symbol is aligned with the left, middle, and right on the effective line, 15 medals will be paid out, and if the "bell" symbol is aligned with the left, middle, and right on the effective line, Eight medals are paid out, and two medals are paid out when the "cherry" symbol on the left reel 42L stops on the effective line. That is, the "cherry" symbols on the middle reel 42M and the right reel 42R are irrelevant to medal payout. In addition, as far as the "cherry" symbol is concerned, medals are paid out regardless of the combination with other symbols, so that the "cherry" symbol is placed at the position where the plurality of effective lines of the left reel 42L overlap (specifically, the upper or lower row). When the "cherry" symbol is stopped, medals are paid out by multiplying the number of overlapping effective lines, and as a result, four medals are paid out in the present embodiment.

Regarding other symbols, when the "red 7" symbol or "white 7" symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, middle, and right on the effective line with the same symbol. 15 medals are paid out, and 15 medals are paid out even when the "BAR" symbol, which is a combination of the second special symbol (regular bonus symbol), is aligned with the left, middle, and right on the effective line. In the present embodiment, for example, the "red 7" symbol and the "cherry" symbol may be established at the same time, and in such a case, 15 medals are paid out. This is because the maximum number of medals to be paid out at one time is set to 15.

Furthermore, if the "replay" symbol, which is a combination of the third special symbols, is aligned with the left, middle, and right on the effective line, the medal will not be paid out. In other cases, that is, if the "cherry" symbol of the left reel 42L does not stop on the effective line and the same symbols as the left, middle, and right are not aligned on the effective line, no medal is paid out.

Here, the bonus game in this embodiment will be described. The regular bonus (hereinafter referred to as "RB") game even consists of 12 JAC games. The JAC game is a game in which only one bet is allowed, and the probability that the JAC symbols (here, the replay symbols are substituted) are aligned on the effective line, that is, the probability that the JAC symbols are established is very high. When the JAC symbol is established in the JAC game, the maximum number of medals (15 in this case) will be paid out. Then, when the JAC symbol is established 8 times, the RB game ends even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as "BB") game is composed of 30 small role games and 3 JAC ins. The small role game is a game in which a small role is won with a high probability (the "bell" pattern etc. are aligned on the effective line), and the JAC in means entering 12 JAC games, and the small role game. When the JAC symbols are aligned on the effective line, the JAC in is established. The JAC game is the same as the case of the RB game. Also, when the JAC game by the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and when the 30 small role games are finished, before the JAC in reaches 3 times. Even if there is, the BB game ends. The form of the bonus game is not limited to the above form, and may be a different form.

By the way, on the lower left side of the game panel 30, a start lever 71 that is operated to start rotating the reels 42L, 42M, and 42R all at once (not necessarily at the same time) is provided. The start lever 71 constitutes a starting operation means that is operated to start rotating the reels 42L, 42M, 42R, that is, to start the variable display. The start lever 71 is a lever that the player pushes and operates by hand when starting the game, and automatically returns to the original position after the hand is released. If the start lever 71 is operated while the medal is being inserted, the reels 42L, 42M, and 42R start rotating all at once.

On the right side of the start lever 71, button-shaped stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. The stop switches 72, 73, and 74 are arranged substantially directly below the display windows 31L, 31M, and 31R corresponding to the reels 42L, 42M, and 42R to be stopped. The stop switches 72, 73, 74 constitute a stop operation means operated to stop the variable display based on the rotation of the reels 42L, 42M, 42R. Each stop switch 72, 73, 74 is in a state where it can be stopped after a predetermined time has elapsed from the start of rotation of the left reel 42L, and during such a state, a lamp (not shown) is lit and displayed to stop. It is notified that the operation is possible, and it is turned off when the rotation stops.

A medal insertion slot 75 for inserting medals is provided on the lower right side of the display windows 31L, 31M, and 31R. The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as the passage switching means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal passage switching solenoid 83 (see FIG. 6) so that the medal passage switching solenoid 83 can be switched to the discharge passage 82 side when not excited and to the storage passage 81 side when excited. It has become. The medal guided to the storage passage 81 is guided to the hopper device 91 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12, and is returned to the player.

The hopper device 91 as a payout means for giving medals to the player is composed of a storage tank 92 for storing medals and a payout device 93 for paying out medals to the player. The payout device 93 discharges medals to the opening 94 provided in the center right portion of the discharge passage 82 by rotating a rotating plate for paying medals (not shown), and medals to the medal tray 18 through the discharge passage 82. Is to be paid out. Further, on the right side of the hopper device 91, a spare tank 95 is provided to prevent medals exceeding a predetermined amount from being stored in the storage tank 92. Inside the storage tank 92 of the hopper device 91, a guide plate 96 for discharging medals from the storage tank 92 to the spare tank 95 is provided. Therefore, when medals are stored above the height at which the guide plate 96 is provided, the medals are stored in the spare tank 95.

A button-shaped return switch 76 is provided below the medal slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal insertion slot 75 is jammed in the selector 84, and when this switch is pressed, the selector 84 is mechanically interlocked to operate, and the selector 84 is operated. The medals packed in the 84 are returned from the medal outlet 17.

On the lower left side of the display windows 31L, 31M, 31R, a button-shaped first credit insertion switch 77 for inserting three credited virtual medals at a time is provided. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 is provided as a button-shaped switch smaller than the switch 77. The second credit insertion switch 78 is for inserting one credited virtual medal at a time.

The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) in order to encourage that the maximum number of medals (3 medals) that can be inserted per game has not been reached. The lamp is lit when the switch operation of the first credit insertion switch 77 is valid to prompt the operation of the switch 77, but when there is no credited virtual medal or three medals have already been inserted. It is turned off under the condition that it is. Here, instead of the above lighting, it may be blinked to make it easier for the player to understand the prompt for inserting the medal.

A button-shaped changeover switch 80 is provided on the left side of the start lever 71. The changeover switch 80 is configured as a toggle type that turns on when pressed once, turns off when pressed again, and switches on and off each time a subsequent pressing operation is performed. The changeover switch 80 is operated to change the handling format of the inserted medals inserted into the medal insertion slot 75 in excess of the required amount and the acquired medals returned to the player as a result of the predetermined game.

When the changeover switch 80 is on, the "credit mode" is set so that the surplus inserted medals and the medals won at the time of winning are stored and stored as credit medals until the predetermined maximum value (for example, 50 medals) is reached. ". When the changeover switch 80 is in the off state, the "direct mode" is set so that the surplus inserted medals and the winning medals at the time of winning are paid out as actual medals. If there is a credit medal when the mode is switched from the credit mode to the direct mode, the credit medal for that amount is paid out as an actual medal. In this way, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for switching the handling type. Further, paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game value. In addition to being configured to switch between "credit mode" and "direct mode" by operating the changeover switch 80, the virtual medal stored and stored is paid out when the changeover switch 80 is operated by always setting the "credit mode". It may function as a payment switch only.

Below the display windows 31L, 31M, 31R of the game panel 30, there is a remaining number display unit 35 that displays the number of medals that are activated and stored in the credit mode, and in special game states such as big bonuses and regular bonuses. For example, a game number display unit 36 for displaying the number of remaining games and the like and an acquired number display unit 37 for displaying the number of acquired medals are provided. These display units 35 to 37 are composed of a 7-segment display, but it is naturally possible to replace them with a liquid crystal display or the like.

Here, the procedure for betting medals will be described. In both the direct mode and the credit mode, when a medal is inserted from the medal insertion slot 75 at the start of the game, a bet is placed.

That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display unit 32 lights up, and the corresponding central line becomes the effective line, and the second medal is the medal insertion slot. When it is inserted into 75, the second effective line display unit 33 lights up, and a total of three combination lines including the corresponding upper line and lower line become effective lines, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further lit, and all five combination lines including a pair of diagonal lines corresponding to the third effective line display unit 34 become effective lines.

When four or more medals are inserted into the medal insertion slot 75, the surplus medals exceeding three are switched to the discharge passage 82 by the selector 84 if the mode at that time is the direct mode. It is returned from the discharge port 17 to the medal tray 18. On the other hand, in the credit mode, the number of saved cards is displayed inside the slot machine and the remaining number display unit 35 displays the number of saved cards. An upper limit is set for the number of stored medals (for example, 50), and when more medals are inserted, the medals are returned from the medal ejection port 17 to the medal tray 18.

In addition, when the game is played in the credit mode and the number of stored sheets is displayed on the remaining number display unit 35, the virtual medal is also displayed when any of the first and second credit insertion switches 77 and 78 is pressed. Is put in and becomes a bet.

For example, when the second credit insertion switch 78 is pressed, one numerical value displayed on the remaining number display unit 35 is decremented as if one virtual medal has been inserted, and the first effective line display unit is displayed. 32 lights up and the center line becomes an effective line. Further, when the first credit insertion switch 77 is pressed, three numerical values displayed on the remaining number display unit 35 are decremented as if three virtual medals have been inserted, and all the effective line display units are displayed. 32 to 34 are lit, and a total of 5 combination lines become effective lines.

The first credit is not stored when any of the first and second credit insertion switches 77 and 78 is pressed, for example, when the display of the remaining number display unit 35 is 2. When the insertion switch 77 is pressed, all the numerical values of the remaining number display unit 35 are decremented to 0, and only the virtual medals that can be inserted are bet.

On the upper part of the front door 12, there is an upper lamp 13 that lights up or blinks as the game progresses, and a pair of left and right lamps that sound various sound effects as the game progresses and notify the player of the game state. The speaker 14A and the first auxiliary display unit 15 for giving various information to the player are provided. Further, the front door 12 is provided with a rectangular frame-shaped second auxiliary display unit 20 that can be visually recognized through the game panel 30 (around the display windows 31L, 31M, 31R).

When the second sliding rod 620 is arranged on the support plate 603, the protrusions 621 and 622 pass through a notch between the lower end of the bulging portion 603a and the general portion of the support plate 603. The front door 12 projects inward from the support plate 603. The first protrusion 621 functions as a detected portion detected by the reset detection sensor 640 described later. On the other hand, the second protrusion 622 functions as an operation unit for manual operation for sliding the second sliding rod 620 downward to perform a reset operation as described later.

Further, the support plate 603 is provided with a mounting base portion 625 protruding inward of the front door 12 at the position of the lower end portion of the bulging portion 603a. A reset detection sensor 640 is mounted on the lower surface side of the mounting base 625. In this embodiment, a transmissive photo sensor is adopted as the reset detection sensor 640. In the normal state, that is, when the second sliding rod 620 is in the reference position, the first protrusion piece 621 is inserted between both elements of the reset detection sensor 640. Then, when there is a downward sliding displacement of the second sliding rod 620, that is, when there is a reset operation via the key K or the second protrusion piece 622 as described later, the first protrusion piece 621 Escapes from between both elements of the reset detection sensor 640, the reset detection sensor 640 detects this, and outputs a detection signal to the main control device 131. The main control device 131 can grasp that the reset operation has been performed based on this detection signal.

The second sliding rod 620 is urged upward by the coil spring C3. More specifically, the mounting plate 602 is formed with a hook portion 602d at a position slightly above the wide portion 602a. On the other hand, a hook portion 627 is formed on the upper piece portion 620b of the second sliding rod 620. Correspondingly, a notch 610 g is formed in the front edge portion of the first sliding rod 610. The hook portion 627 of the second sliding rod 620 is in a state of protruding outward from the front door 12 from the first sliding rod 610 via the notch portion 610 g of the first sliding rod 610. Then, one end of the coil spring C3 is hooked on the hook portion 602d of the mounting plate 602, and the other end is hooked on the hook portion 627 of the second sliding rod 620.

The second sliding rod 620 is normally held at a reference position as shown in FIG. 7 or the like by the tensile force of the coil spring C3. In this state, the second sliding rod 620 is in a state in which the upward movement is suppressed by urging the protruding pieces 621 and 622 to the lower end portion of the bulging portion 603a. Further, in this state, as described above, the first protrusion piece 621 is in a state of being inserted between both elements of the reset detection sensor 640. Then, when there is a downward sliding displacement of the second sliding rod 620, the first protrusion piece 621 is in a state of being pulled out from between both elements of the reset detection sensor 640.

Next, the third sliding rod 630 will be described in detail. The third sliding rod 630 is for locking the protective cover 21, and is provided corresponding to a section from a position slightly below the main hook member 611 to a position slightly above the bulging portion 603a.

The third sliding rod 630 has a long shape and is slidably arranged in the vertical direction along the support plate 603. More specifically, guide holes 630a are formed in the upper portion and the lower portion of the third sliding rod 630, respectively. Each guide hole 630a has an oval shape that is long in the vertical direction. Then, the guide pin P630 inserted into the guide hole 630a from the outer side of the front door 12 of the third sliding rod 630 is fixed to the fixing hole 603g of the support plate 603.

The third sliding rod 630 can slide in the vertical direction while being restricted by the guide pin P630 in the left-right direction (horizontal direction in FIG. 11) and in the front-rear direction (horizontal direction in FIG. 12). There is.

A pair of upper and lower hook members 630c and an operating portion 630d are formed so as to project rearward on the third sliding rod 630.

The third sliding rod 630 is urged upward by the coil spring C4. More specifically, the mounting plate 602 is formed with a hook portion 602e. On the other hand, the hook portion 630e is formed on the third sliding rod 630. Correspondingly, a notch 610h is formed in the front edge portion of the first sliding rod 610. The hook portion 630e of the third sliding rod 630 is in a state of protruding outward from the front door 12 from the first sliding rod 610 via the notch portion 610h of the first sliding rod 610. Then, one end of the coil spring C4 is hooked on the hook portion 602e of the mounting plate 602, and the other end is hooked on the hook portion 630e of the third sliding rod 630.

The third sliding rod 630 is normally held at a reference position as shown in FIG. 7 or the like by the tensile force of the coil spring C4. In this state, the third sliding rod 630 is in a state in which the upward movement is suppressed by urging the guide pin P630 to the lower edge portion of the guide hole 630a.

When the protective cover 21 is in the closed state, the third sliding rod 630 is located at the reference position, so that the hook member 630c is relative to the pair of engaged portions (not shown) provided on the protective cover 21. Is engaged and the engaged state is maintained.

The operating portion 630d of the third sliding rod 630 is exposed only when the front door 12 is opened, and can be operated only in that case. Then, by pushing down the operating portion 630d against the tensile force of the coil spring C4, the engaged state is released and the protective cover 21 is unlocked.

By the way, a cylinder lock 700 as a lock member is attached to the wide portion 602a of the attachment plate 602. As shown in FIGS. 22 and 23, the cylinder lock 700 includes a cylinder body 701 having a substantially tubular shape, a lock shaft 703 provided inside the cylinder body 701 and having a keyhole 702 inside, and a cylinder body 701. It is provided with an outer cylinder 704 provided on the outer periphery.

The cylinder lock 700 is screwed and fixed by the back side of the mounting plate 602 via the pedestal member 705 in a state where the cylinder body 701 is inserted through the mounting hole 602j of the mounting plate 602.

The cylinder body 701 is formed with a total of 16 through holes 706, eight at the top and eight at the bottom, which communicate with each other inside and outside the cylinder body 701. Correspondingly, the lock shaft 703 is also formed with 16 through holes 708 communicating with each through hole 706. The keyhole 702 side of the through hole 708 is formed to have a smaller diameter than other portions so that an accommodating member such as a pin 714, which will be described later, does not fall into the keyhole 702.

A spring 709 is housed in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and the pedestal 711 is connected to the other end. Further, in each through hole 708, a plurality of spacers 712, 713 and pins 714 are housed so as to be supported by the pedestal 711. The pins 714, spacers 712, 713, and pedestal 711 can move up and down in the through holes 706 and 708 by expanding and contracting the spring 709. Of these, the pin 714 can appear and disappear in the keyhole 702 via the small diameter portion of the through hole 708 on the keyhole 702 side.

With the above configuration, when the key K is inserted into the keyhole 702, each pin 714 or the like moves up and down along the uneven shape on both the upper and lower sides of the key K. When the key K has been inserted, each pin 714 is in the groove of the key K as shown in FIG. 23, and the base end surface of the pin 714 or one end surface of the spacer 712 or 713. And the outer peripheral surface of the lock shaft 703 are flush with each other. As a result, when the key K has been inserted, the lock shaft 703 can rotate with the rotation operation of the key K. That is, the cylinder lock 700 has an internal structure in which the lock shaft 703 cannot be rotated unless the key K is inserted into the keyhole 702 at least.

Further, a cam plate 720 that transmits the rotational operation of the key K inserted into the keyhole 702 to the first sliding rod 610 or the second sliding rod 620 is fixed to the rear end portion of the lock shaft 703.

The cam plate 720 includes a pair of upper and lower engaging claws 720a and a lower engaging claw 720b. These engaging claws 720a and 720b are formed at predetermined intervals in the rotation direction of the cam plate 720 (see FIG. 9 and the like).

In line with this, the bulging portion 610c of the first sliding rod 610 is formed with a pair of upper and lower engaging holes 725 and lower engaging holes 726 through which the engaging claws 720a and 720b can enter and exit. Similarly, the lower piece portion 620a of the second sliding rod 620 is formed with a pair of upper and lower engaging holes 727 and a lower engaging hole 728 through which the engaging claws 720a and 720b can move in and out. Further, a through hole 730 is formed in the bulging portion 603a of the support plate 603 so as not to interfere with the operation of the engaging claws 720a and 720b.

The engaging holes 725 and 726 of the first sliding rod 610 and the engaging holes 727 and 728 of the second sliding rod 620 are the lower pieces of the bulging portion 610c of the first sliding rod 610 and the second sliding rod 620. In the superposed state of the portion 620a, at least the upper engaging holes 725 and 727 and the lower engaging holes 726 and 728 are in a communicating state (see FIG. 14 and the like).

On the first sliding rod 610 side, the upper engaging hole 725 located above the both engaging holes 725 and 726 is set to have a longer vertical formation section than the lower engaging hole 726. Has been done. On the other hand, on the second sliding rod 620 side, the lower engaging hole 728 located below the both engaging holes 727 and 728 has a longer vertical formation section than the upper engaging hole 727. Is set to. This is so that when the cam plate 720 slides one of the first sliding rod 610 and the second sliding rod 620, the upper engaging claw 720a or the lower engaging claw 720b does not come into contact with the other. This is to prevent the other from sliding.

Under the above configuration, when the lock shaft 703 and the cam plate 720 are in the reference position when the key K is not inserted into the keyhole 702 of the cylinder lock 700, the tip of the upper engaging claw 720a is the first. The first sliding rod 610 and the second sliding rod 620 are inserted into the upper engaging holes 725 and 727, and the tip of the lower engaging claw 720b is the first sliding rod 610 and the second sliding rod 620. It is inserted into the lower engagement holes 726 and 728.

As a result, when the first sliding rod 610 is moved in the unlocking direction (upward) by a force other than the cam plate 720 in the closed state of the front door 12, for example, the first sliding rod 610 without using the key K. When an external force is applied in the unlocking direction by illegally hooking a wire rod or the like, the lower edge portion of the lower engaging hole 726 comes into contact with the lower engaging claw 720b of the cam plate 720, whereby the first It is possible to prevent the sliding rod 610 from sliding in the unlocking direction and prevent unauthorized unlocking.

As described above, the cylinder lock 700 of the present embodiment is in a state (locked state) in which the lock shaft 703 and the cam plate 720 cannot be rotated when the key K is not inserted in the keyhole 702. Therefore, even if the lower edge portion of the lower engaging hole 726 is caught by the lower engaging claw 720b of the cam plate 720, the cam plate 720 does not rotate, and the upward sliding displacement of the first sliding rod 610 does not occur. , Except for the play width, it is practically regulated.

Further, cover members 671 and 672 made of synthetic resin are screwed and fixed to the central portion and the lower end portion in the longitudinal direction of the support plate 603. The lower rear ends of the cover members 671 and 672 have an R shape. This is for preventing the locking device 600 and the receiving metal fitting 800 from being displaced when the front door 12 is closed with respect to the housing 11, and for smoothly closing the front door 12.

Next, the receiving metal fitting 800 will be described in detail with reference to FIGS. 7 and 8 and FIGS. 15 to 21. 15 is a left side view of the receiving metal fitting 800, FIG. 16 is a front view, FIG. 17 is a right side view, and FIG. 18 is a rear view. FIG. 19 is a right side view showing the locking device 600 and the receiving metal fitting 800 in the locked state, FIG. 20 is a left side view, and FIG. 21 is a rear view.

The receiving metal fitting 800 includes a vertically long plate portion 801 that is mounted and fixed inside the right side plate 11e of the housing 11. The plate portion 801 corresponds to the covering member in the present embodiment.

A bulging portion 802 bent toward the outer side of the housing 11 is provided over substantially the entire longitudinal direction of the front edge portion of the plate portion 801. The bulging portion 802 is for smoothly closing the front door 12 without the locking device 600 being caught by the front edge portion of the plate portion 801 when the front door 12 is closed with respect to the housing 11. ..

The plate portion 801 is provided with a pair of upper and lower hook receiving portions 803 and 804 as engaged portions that engage with the main hook members 611 and 612 of the locking device 600. The hook receiving portions 803 and 804 are formed so as to project from the trailing edge portion of the plate portion 801 toward the inward side of the housing 11.

Engagement holes 803a and 804a are formed in the hook receiving portions 803 and 804 corresponding to the return portions 613c and 614c of the auxiliary hook members 613 and 614. When the main hook members 611 and 612 are engaged with the hook receiving portions 803 and 804, the return portions 613c and 614c of the secondary hook members 613 and 614 are inserted into the engaging holes 803a and 804a so that they can be engaged. [See FIG. 24 (a) and the like].

The trailing edge of the support plate 603 of the locking device 600 is opposed to the return portions 613c and 614c of the auxiliary hook members 613 and 614 (engagement holes 803a and 804a of the hook receiving portions 803 and 804). A guard portion 603h projecting outward from the front door 12 is formed. The guard portion 603h disengages the return portions 613c and 614c of the secondary hook members 613 and 614 from the engagement holes 803a and 804a of the hook receiving portions 803 and 804 so that the return portions 613c and 614c are not pushed from the front by a wire rod or the like. This is to make it difficult. That is, it has a function of preventing an illegal unlocking operation for the auxiliary hook members 613, 614 and the like.

Further, guard portions 803b and 804b projecting rearward are formed at the tip edge portions (end edges on the inner side of the housing 11) of the hook receiving portions 803 and 804. The guard portions 803b and 804b are for preventing the wire rod and the like from entering and making it difficult for the wire rod and the like to be caught on the auxiliary hook members 613 and 614 and the like. That is, it has a function of preventing an illegal unlocking operation for the auxiliary hook members 613, 614 and the like.

Further, the plate portion 801 is formed with a guard wall portion 805 at a position corresponding to the cylinder lock 700 (cam plate 720). The guard wall portion 805 is formed so as to project inward from the trailing edge portion of the plate portion 801 toward the inside of the housing 11. The guard wall portion 805 has a function as a detected portion that comes into contact with the open detection switch 650, and also prevents wire rods and the like from entering the inside of the base frame 601 to prevent the wire rod and the like from entering the inside of the base frame 601. It is equipped with a function to prevent an illegal unlocking operation of the 700 cam plate 720 or the like (see FIG. 21 or the like).

Corresponding to the guard wall portion 805, the support plate 603 is provided with a mounting base portion 626 protruding inward of the front door 12 at the rear end edge portion of the bulging portion 603a. An open detection switch 650 is attached to the attachment base 626.

The open detection switch 650 is attached so that the switch portion 650a faces rearward. With this configuration, when the front door 12 is closed, the switch portion 650a is pressed against the guard wall portion 805 on the receiving metal fitting 800 side, so that the switch portion is immersed in the switch body (see FIG. 20). .. On the other hand, when the front door 12 is in the open state, the switch portion 650a is in a state of protruding from the switch main body by separating from the guard wall portion 805 on the receiving metal fitting 800 side (see FIG. 14 and the like).

The open detection switch 650 outputs an on signal when the switch unit 650a is in the protruding state, and outputs an off signal when the switch unit 650a is in the immersive state. That is, when the front door 12 is in the open state, an ON signal is output from the open detection switch 650 to the main control device 131. Based on this ON signal, the main control device 131 grasps that the front door 12 has been opened.

Further, the plate portion 801 is formed with ribs 806 in most of the sections in the vertical direction between the upper and lower hook receiving portions 803 and 804. The rib 806 is formed so as to project inward from the trailing edge of the plate 801 toward the inside of the housing 11. The rib 806 has a function of preventing the wire rod or the like from entering the inside of the base frame 601 and preventing an illegal unlocking operation of the first sliding rod 610 or the like (see FIG. 21 or the like).

Next, the operations of the locking device 600 and the receiving metal fitting 800 will be described in detail. When the front door 12 is locked to the housing 11, that is, when the locking device 600 and the receiving metal fitting 800 are locked, the first sliding rod 610 takes a reference position as shown in FIG. 24 (a). The main hook members 611 and 612 are engaged on the back side of the hook receiving portions 803 and 804, and the opening of the front door 12 is restricted.

In the closed state of the front door 12, as described above, the cam plate 720 of the cylinder lock 700 and the lower engaging hole 726 of the first sliding rod 610 are engaged with each other to move upward of the first sliding rod 610. The sliding displacement is substantially regulated except for the play width. That is, the first sliding rod 610 is configured so that the secondary hook members 613 and 614 and thus the main hook members 611 and 612 are not displaced.

As shown in FIG. 24A, when the main hook members 611 and 612 are engaged with the hook receiving portions 803 and 804, the return portions 613c and 614c of the secondary hook members 613 and 614 are hooked portions 803 and 614c. It is in a state of being inserted into the engagement holes 803a and 804a of the 804. Such a state corresponds to a locked state (regulated state) of the auxiliary hook members 613 and 614.

In such a state, if the main hook members 611 and 612 are to be moved in the unlocking direction by an illegal external force that does not involve the operation of the key K (the operation of the first sliding rod 610), for example, the main hook members 611, When a wire rod or the like is illegally hooked on the 612 and an external force is applied to the main hook members 611 and 612 in the unlocking direction without passing through the first sliding rod 610, the main hook members 611 and the main hook members 611 are first applied. The 612 attempts to rotate and displace around the shaft pins P611 and P612 in the unlocking direction (clockwise when viewed from the outside of the front door 12).

Along with this, the auxiliary hook members 613 and 614 are integrally rotated together with the main hook members 611 and 612 around the shaft pins P611 and P612 in a state where the engaging pieces 613f and 614f are pulled downward by the coil springs C1 and C2. Attempts to move and displace.

As a result, as shown in FIG. 25, the positions of the shaft pins P613 and P614, which are the rotating shafts, of the auxiliary hook members 613 and 614 are lowered downward while maintaining the relative positional relationship with the main hook members 611 and 612. , The return portions 613c and 614c are hooked on the lower edges of the engagement holes 803a and 804a of the hook receiving portions 803 and 804. As a result, the main hook members 611 and 612 cannot be rotationally displaced in the unlocking direction any more. That is, the main hook members 611 and 612 cannot be displaced to the non-engaged position, and the front door 12 cannot be opened.

On the other hand, when the front door 12 is normally opened, the key K is inserted into the keyhole 702 of the cylinder lock 700 and rotated clockwise when viewed from the front side (see FIG. 1) of the slot machine 10. This operation corresponds to a specific operation in this embodiment. As a result, the cam plate 720 rotates in the same direction, and the lower engaging claw 720b comes into contact with the upper edge portion of the lower engaging hole 726 of the first sliding rod 610.

After that, as the cam plate 720 is further rotated, the lower engaging claw 720b pushes up the first sliding rod 610 against the tensile force of the coil springs C1 and C2. At this time, since a space for the lower engaging claw 720b to be displaced upward is secured in the upper part of the lower engaging hole 728 of the second sliding rod 620 through which the lower engaging claw 720b is inserted, the first sliding In the process of pushing up the moving rod 610, the lower engaging claw 720b does not come into contact with the second sliding rod 620 so that its operation is not hindered.

When the first sliding rod 610 slides upward, as shown in FIG. 24 (b), the engaging pieces 613f and 614f of the auxiliary hook members 613 and 614 first cut the first sliding rod 610. It is pushed up by the lower edge portion of the notch portion 610f, and the auxiliary hook members 613 and 614 are rotationally displaced relative to the main hook members 611 and 612 about the shaft pins P613 and P614.

As a result, the return portions 613c and 614c of the sub-hook members 613 and 614 come out from the engagement holes 803a and 804a of the hook receiving portions 803 and 804, and the heads from the engagement recesses 611a and 612a of the main hook members 611 and 612. It is in a state of being retracted to the 611b and 612b sides. As a result, the locked state by the auxiliary hook members 613 and 614 is released. Such a state corresponds to an unlocked state (regulation released state) of the auxiliary hook members 613 and 614.

From here, when the first sliding rod 610 is further slid upward and the sub-hook members 613 and 614 are rotationally displaced, the vertical pieces 613b and 614b of the sub-hook members 613 and 614 become the main hook members 611. , 612 come into contact with the engaging protrusions 611h and 612h, and the auxiliary hook members 613 and 614 (vertical piece portions 613b and 614b) push the main hook members 611 and 612 in the unlocking direction [FIG. 24 (b). )reference〕.

As described above, since the locked state by the sub-hook members 613 and 614 is released at this stage, the main hook members 611 and 612 and the sub-hook members 613 and 614 resist the tensile force of the coil springs C1 and C2. , The shaft pins P611 and P612 are integrally rotated and displaced in the unlocking direction (clockwise when viewed from the outside of the front door 12).

It should be noted that the return portion 613c, when the main hook member 611, 612 and the secondary hook member 613, 614 are integrally rotationally displaced depending on whether the secondary hook members 613 and 614 are in the locked state and in the unlocked state. Since the trajectories through which the 614c pass are different, here, the return portions 613c and 614c are not caught in the lower edges of the engagement holes 803a and 804a of the hook receiving portions 803 and 804, and the main hook members 611 and 612 are on the non-engagement position side. It becomes possible to displace to.

Then, when the main hook members 611 and 612 are displaced to the non-engaging positions, the engagement with the hook receiving portions 803 and 804 is released (non-engaging state), and the front door 12 is allowed to be opened.

When the force of the hand operating the key K is relaxed when the front door 12 is opened, the first sliding rod 610 is pulled downward by the tensile force of the coil springs C1 and C2 and returns to the reference position. To do. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference positions.

As described above, in the present embodiment, when the key K is not inserted into the keyhole 702 of the cylinder lock 700, the sliding of the first sliding rod 610 is restricted, but the front door in the open state is restricted. When locking 12, the lock can be performed without using the key K.

More specifically, when the front door 12 is closed from the open state of the front door 12 in which the locking device 600 and the receiving metal fitting 800 are unlocked, first, the heads 611b and 612b of the main hook members 611 and 612 are closed. The inclined portions 611c and 612c come into contact with the lower sides of the hook receiving portions 803 and 804.

When the front door 12 is further closed, the main hook members 611 and 612 are rotationally displaced in the unlocking direction around the shaft pins P611 and P612. Then, while pushing down the positions of the shaft pins P613 and P614 that pivotally support the sub-hook members 613 and 614, the engaging protrusions 611i and 612i of the main hook members 611 and 612 are the lateral pieces of the sub-hook members 613 and 614. Push up 613a and 614a. As a result, the main hook members 611 and 612 and the sub-hook members 613 and 614 are integrally rotationally displaced in the unlocking direction against the tensile force of the coil springs C1 and C2.

After that, when the heads 611b, 612b (inclined portions 611c, 612c) of the main hook members 611, 612 and the return portions 613c, 614c of the auxiliary hook members 613, 614 get over the hook receiving portions 803, 804, the main hook members 611 The 612 and the auxiliary hook members 613 and 614 return to their original positions due to the tensile force of the coil springs C1 and C2.

As a result, the hook receiving portions 803 and 804 enter the engaging recesses 611a and 612a of the main hook members 611 and 612, and the heads 611b and 612b of the main hook members 611 and 612 engage with the back side of the hook receiving portions 803 and 804. It is combined [see FIG. 24 (a)].

When the main hook members 611 and 612 return to their original positions, the secondary hook members 613 and 614 also return to their original states, and the return portions 613c and 614c of the secondary hook members 613 and 614 are the engagement holes of the hook receiving portions 803 and 804. It is in a state of being inserted through 803a and 804a. As a result, the locking is completed, the opening of the front door 12 is restricted, and the displacement of the main hook members 611 and 612 in the unlocking direction by the auxiliary hook members 613 and 614 is substantially excluding the play width. It becomes a regulated state (locked state).

Next, the reset operation will be described in detail. In the closed state of the front door 12, the second sliding rod 620 takes a reference position, so that the first protrusion piece 621 is inserted between the two elements of the reset detection sensor 640 as described above.

When the reset operation is performed in the closed state of the front door 12, the key K is inserted into the keyhole 702 of the cylinder lock 700 and rotated in the counterclockwise direction when viewed from the front side of the slot machine 10. As a result, the cam plate 720 rotates in the same direction, and the upper engaging claw 720a comes into contact with the lower edge portion of the upper engaging hole 727 of the second sliding rod 620.

After that, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes down the second sliding rod 620 against the tensile force of the coil spring C3. At this time, since a space for the upper engaging claw 720a to be displaced downward is secured in the lower part of the upper engaging hole 725 of the first sliding rod 610 through which the upper engaging claw 720a is inserted, the second sliding In the process of pushing down the moving rod 620, the upper engaging claw 720a does not come into contact with the first sliding rod 610, and its operation is not hindered.

When the second sliding rod 620 slides downward, the first protrusion piece 621 comes out from between both elements of the reset detection sensor 640, the reset detection sensor 640 detects this, and outputs a detection signal to the main control device 131. To do. The main control device 131 can grasp that the reset operation has been performed based on this detection signal. This makes it possible to reset an error state such as a hopper error without opening the front door 12.

Then, when the force of the hand operating the key K is relaxed, the second sliding rod 620 is pulled upward by the tensile force of the coil spring C3 and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference positions.

On the other hand, in the open state of the front door 12, the same reset operation as described above can be performed by manually operating the second protrusion piece 622 and sliding the second sliding rod 620 downward. As described above, the slot machine 10 has a backup function for various data, maintains the state at the time of a power failure even in the event of a power failure, and at the time of a power failure when recovering from the power failure (recovery of power). It is possible to return to the state of. Therefore, if the power is turned off in the normal procedure as in the case where the game hall is closed, the state before the power is cut off is stored in memory. However, if the power switch 122 is turned on while pressing the second protrusion 622, for example, the backup data will be saved. It is supposed to be reset.

As described in detail above, in the present embodiment, when the key K is not inserted in the cylinder lock 700, the cam plate 720 and the lower engagement hole 726 are engaged with each other to move upward from the first sliding rod 610. The sliding displacement of the above is substantially regulated except for the play width.

Further, by providing the secondary hook members 613 and 614, when the front door 12 is closed, the main hook members 611 and 612 are directly unlocked by a wire rod or the like without using the key K, that is, illegal unlocking. When the operation is performed, the displacement of the main hook members 611 and 612 in the unlocking direction is restricted. That is, since the main hook members 611 and 612 are substantially maintained at the engaged positions except for the play width, the front door 12 is not allowed to be opened.

On the other hand, when the unlocking operation is normally performed using the key K, the auxiliary hook members 613 and 614 change their states by receiving a force from the first sliding rod 610, and the main hook members 611 and 612 change their states. It can be displaced to the non-engagement position side. That is, the main hook members 611 and 612 are separated from the hook receiving portions 803 and 804, and the front door 12 is allowed to be opened.

Further, in the present embodiment, when the front door 12 in the open state is locked, the lock can be performed without using the key K. More specifically, when the front door 12 is locked, the inclined portions 611c and 612c of the main hook members 611 and 612 come into contact with the hook receiving portions 803 and 804 once against the tensile force of the coil springs C1 and C2. Along with the displacement in the unlocking direction, the auxiliary hook members 613 and 614 are also integrally rotationally displaced in accordance with this. After that, the tensile force of the coil springs C1 and C2 returns the main hook members 611 and 612 and the secondary hook members 613 and 614 to their original positions, and the locking is completed. As a result, the opening of the front door 12 is restricted, and the lock is locked by the auxiliary hook members 613 and 614. With such a configuration, the front door 12 can be smoothly closed without the auxiliary hook members 613 and 614 getting in the way, and workability is improved.

Further, since the upper and lower main hook members 611 and 612 are configured to rotate and displace independently, one of the main hook members 611 and 612 may be temporarily displaced in the unlocking direction due to fraudulent activity. Even if the door 12 is closed, the first sliding rod 610 is not interlocked with the first sliding rod 610 and the other is not displaced. Therefore, the locked state of the front door 12 is maintained and opening is not allowed. As a result, the synergistic effect with the sub-hook members 613 and 614 that regulate the displacement of the main hook members 611 and 612 in the unlocking direction further improves the protective performance against unauthorized unlocking.
[Second Embodiment]
Hereinafter, the second embodiment will be described with reference to FIG. 26. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The arrangement position of the sliding member such as the moving rod 610 is not limited to each of the above embodiments.

For example, in the first embodiment, the sub-hook members 613 and 614 may be arranged between the main hook members 611 and 612 and the support plate 603, and in the second embodiment, the sub-hook members 903 and the base frame ( The main hook member 902 may be arranged between the support plate) 900.

(I) In each of the above embodiments, the cylinder lock 700 is locked when the key K is not inserted, and the sliding displacement of the sliding member such as the first sliding rod 610 is regulated by the cam plate 720. doing. Not limited to this, for example, when a sliding member such as the first sliding rod 610 is in the reference position, both engaging claws 720a and 720b of the cam plate 720 are inserted into the engaging holes 725 and 726 and the like. A configuration may be adopted in which the sliding of the sliding member such as the first sliding rod 610 is not regulated without being in a state. Further, a cylinder lock that does not lock even when the key K is not inserted (the cam plate 720 does not become displaceable) may be adopted. However, in this case, in order to enhance the defense control against an illegal unlocking operation performed directly on the sliding member such as the first sliding rod 610 without using the key K, the first sliding rod 610 It is preferable to provide some means capable of regulating the displacement of the sliding member such as.

(J) In the first embodiment, the return portions 613c and 614c for restricting the displacement of the main hook members 611 and 612 in the unlocking direction may be omitted from the auxiliary hook members 613 and 614. Similarly, in the second embodiment, the regulation piece 903a for restricting the displacement of the main hook member 902 in the unlocking direction may be omitted from the sub-hook member 903. However, in such a configuration, as shown in (b) above, the main hook member such as the main hook member 611, 612 and the sub hook member such as the sub hook member 613, 614 are independently provided. It is preferable to be

According to this configuration, two hook members (main hook member and sub-hook member) are engaged with one engaged portion. Therefore, when the front door 12 is locked, the key K is not used. Even if an external force is directly applied to one of the main hook member or the secondary hook member by a wire rod or the like, that is, even if an illegal unlocking operation is performed, the other hook member Is maintained in the engaged position, so opening of the front door 12 is not allowed. As a result, it is possible to improve the defense performance against unauthorized unlocking using a wire rod or the like.

(K) It may be implemented as a slot machine (rotary drum type gaming machine) of a type different from each of the above embodiments. Further, in addition to the slot machine, it may be applied to other gaming machines such as a pachinko machine and a gaming machine in which a slot machine and a pachinko machine are fused.

In a configuration including a plurality of door bodies such as a pachinko machine, for example, the locking mechanism of the first door body and the locking mechanism of the second door body may be embodied by a single locking device. .. In such a case, both the locking mechanism of the first door body and the locking mechanism of the second door body are provided with a main hook member such as a main hook member 611 and 612 and a secondary hook member such as a secondary hook member 613 and 614, respectively. It may be configured as a new type.

Further, the unlocking operation of the first door body and the unlocking operation of the second door body may be separately executed while sharing one sliding member. For example, by inserting the key K into the keyhole 702 of the cylinder lock 700 and rotating it clockwise, the first door body is unlocked, and by rotating it counterclockwise, the second door body is unlocked. It may be configured to be.

In order to share one sliding member and unlock the two door bodies separately, at least the hook member in the locking mechanism of one door body is displaced relative to the sliding member. There is no choice but to provide it as possible. Therefore, from the viewpoint of fraud prevention, it is necessary to configure the hook member so that the hook member is not displaced by the direct unlocking operation of the hook member.

In this regard, in the present application, by providing the secondary hook members such as the secondary hook members 613 and 614, an illegal unlocking operation by a wire rod or the like without using a key (direct solution to the main hook members such as the main hook members 611 and 612). By the lock operation), it is possible to prevent the main hook members such as the main hook members 611 and 612 from moving toward the non-engaging position side.

Hereinafter, technical ideas that are not described in the claims and can be grasped from the above-described embodiment will be described together with their effects.

Means A1. A door body that is openable and closable to support members (such as the outer frame of a pachinko machine and a fixed frame for a slot machine housing, etc.)
A gaming machine provided with a locking device attached to either the support member or the door body and locking the door body to the support member.
The locking device is
The lock member operated by the key and
A sliding member provided so as to be slidable in conjunction with the operation of the lock member,

According to the above means A1, when the door body is locked by providing the regulating member, when an external force is directly applied to the hook member by a wire rod or the like without using a key, that is, it is illegal. When the unlocking operation is performed properly, the displacement of the hook member in the unlocking direction is restricted. That is, since the hook member is maintained in the engaged position, opening of the door body is not allowed. As a result, it is possible to improve the defense performance against unauthorized unlocking using a wire rod or the like.

On the other hand, when the unlocking operation is performed normally using the key, the regulating member changes its state from the regulated state to the deregulated state due to the action from the sliding member, and the hook member moves to the non-engaged position. It can be displaced. That is, the hook member is disengaged from the engaged portion, and the door body is allowed to be opened.

The same applies to the following means, but the number of hook members and the corresponding engaged portions is not limited to one, and a plurality of these may be provided (regulating members and the like). The same applies). In this case, it is preferable that the regulating member is provided corresponding to each of the plurality of hook members. In this way, the defense performance against unauthorized unlocking can be further improved. However, if at least one is provided, the protective performance against unauthorized unlocking can be sufficiently exhibited.

Further, examples of the lock member include a cylinder lock in which a key is inserted and rotated. In this case, the operating portion operated by the key is composed of a lock shaft provided so as to be rotatable, an engaging piece (cam plate) fixed to the lock shaft, and the like. Of course, the lock member is not limited to the cylinder lock, and other lock members may be adopted.

Further, in a configuration in which the regulating member changes its state "in conjunction with the operation of the sliding member", the sliding member and the regulating member are integrally formed, or the sliding member cannot be relatively displaced by a fixing means such as a screw. It also includes a configuration in which both are fixed to each other and move in an integrated manner. Therefore, the regulating member may have a configuration integrally formed with the sliding member, a configuration fixed so as not to be relatively displaceable with respect to the sliding member, or a configuration provided so as to be relatively displaceable with the sliding member. ..

In addition, the "engagement position that regulates the opening of the door body" of the hook member is the position where the door body cannot be opened in contact with the engaged portion when the closed door body is moved in the opening / closing direction. Point to. Further, the "non-engaged position that allows the door body to be opened" of the hook member is a position that does not contact the engaged portion or a door that is in contact with the engaged portion when the closed door body is moved in the opening / closing direction. Refers to the position where the body can be opened.

Means A2. A door body that can be opened and closed on one side of the left and right sides of the support member (such as the outer frame of the pachinko machine or the fixed frame of the slot machine housing).
A gaming machine provided with a locking device that is attached along the left and right other sides of either the support member or the door body and locks the door body to the support member.
The locking device is

The lock member operated by the key and
A sliding member provided along the support portion so as to be slidable in the vertical direction in conjunction with the operation of the lock member in response to the operation of the key.
An engaging position that is engaged (in the opening / closing direction of the door body) with the support member or an engaged portion provided on the other side of the door body to restrict the opening of the door body, and the engaged portion. A hook member displaceable at a non-engagement position that allows the door body to be opened by separating from the portion, and
An urging means capable of urging the hook member toward the engaging position side, and
A regulation member (lock member) provided so as to be able to change the state between a regulation state in which the displacement of the hook member can be regulated at least in the closed state of the door body and a regulation release state in which the displacement of the hook member is allowed.
Provided with a maintenance means capable of maintaining the regulating member in the regulated state,
The sliding member slides in conjunction with the operation of the lock member in response to a specific operation by the key, and the restricting member moves from the restricted state to the deregulated state in conjunction with the operation of the sliding member. A gaming machine characterized in that the hook member is allowed to be displaced toward the non-engaging position side (unlocking direction) by changing the state to.

According to the means A2, the same effects as those of the means A1 are exhibited. The "left and right one side portion" refers to one side in the left and right direction, and if the "left and right one side portion" is, for example, the "right side portion", the "left and right other side portion" is the "left side portion". On the contrary, if the "left and right one side portion" is the "left side portion", the "left and right other side portion" is the "right side portion".

Further, the configuration in which the urging means "can urge the hook member to the engaging position side" includes, for example, a configuration in which the hook member is directly urged, or an indirect configuration via a sliding member, a regulating member, or the like. Includes configurations that are urged to. Similarly, the configuration in which the maintenance means can "maintain the regulated member in the regulated state" includes, for example, a configuration in which the regulated member is directly maintained, a configuration in which the regulated member is indirectly maintained via a sliding member, and the like. Is done.

Here, by embodying the urging means and the maintaining means with a single urging member (for example, an elastic member such as a coil spring), it is possible to suppress an increase in the number of parts and simplify the configuration. ..

Means A3. At least when the door body is in the open state, the hook member is configured to be able to be displaced toward the non-engagement position side in accordance with the regulation member that moves in conjunction with the operation of the sliding member. The gaming machine according to means A1 or A2.

The term "following" as used herein means a member that receives an action from a regulating member or is acted on by the regulating member without directly receiving an action (power transmission) from a sliding member like a regulating member (a member that receives an action from the regulating member (power transmission). For example, it means that it operates in the same direction by being acted on via a shaft pin).

If the regulating member and the hook member are individually configured to move in conjunction with the movement of the sliding member, there is a risk that the regulating member and the hook member may be displaced due to their assembly errors or the like. There is. If such an operation deviation occurs, the locked state of the door body may not be properly released, for example, the hook member tries to be displaced to the non-engaging position side without properly releasing the regulated state by the regulating member. There is.

On the other hand, according to the means A3, the regulating member and the hook member operate stepwise, and the above-mentioned operation deviation and the like are less likely to occur in each member.

Means A4. The regulating member is engaged with a predetermined portion (for example, an engaged portion with which the hook member is engaged) provided on the support member or the other side of the door body in the closed state of the door body. The gaming machine according to any one of means A1 to A3, which is characterized in being in a regulated state.

For example, when the regulating member is directly engaged with the hook member to make the hook member non-displaceable, when the door body is closed without using the key, the hook member and the engaged portion are engaged. Collide with each other, which may cause problems such as deformation or breakage of the hook member or the engaged portion.

In this respect, according to this means, the above-mentioned problem does not occur when the door body in the open state is closed with respect to the support member. Further, if the "predetermined portion" is, for example, "the engaged portion with which the hook member is engaged", an increase in the number of parts can be suppressed and the configuration can be simplified.

Means A5. The gaming machine according to any one of means A1 to A4, wherein the regulating member is assembled so as to be relatively displaceable with respect to the hook member.
