The main body 75 has rails 77 formed at the upper and lower ends, can fix the printed circuit board 60B, and the cover 76 is provided with an IO board connector 60A. Then, by fixing the screw fixing portions 78 provided respectively on the sides of the main body 75 and the cover 76 from the main body 75 side with screws (not shown), the printed circuit board 60B is housed inside the case. Yes. Since screws are fixed from the side of the main body 75 in this way, the screws are not exposed on the front surface of the cover 76 (that is, the front surface when attached to the housing 1).

On the other hand, as shown in FIGS. 9 and 10, the slide member 50 is a thin plate member in which upper and lower end portions of the base plate 51 are formed with locking portions 52 that are substantially L-shaped in side view and project to the front side. The inside of the locking part 52 is a groove part 53 that can hold the rail part 77 of the IO board case 74. Further, a mounting portion 54 that protrudes to the side is provided at a side end portion of the base plate 51, and screws are inserted into screw holes 54 a and 54 b formed in the mounting portion 54, so that the back of the housing 1. It is fixed to the surface of the plate 18.
The IO board 60 slides in the left-right direction by fitting the rail part 77 of the IO board case 74 from the side into the groove part 53 of the slide member 50 and engaging the rail part 77 and the locking part 53. It is freely supported by the slide member 50 (see FIG. 12). By fixing the slide member 50 to which the IO substrate 60 is attached in this way to the back plate 18, the IO substrate 60 is attached to the back plate 18 so as to be slidable in the left-right direction.

As shown in FIGS. 7 and 11, the main board 24 is screwed from the back side of the support 21. Q is fixed. That is, when the main board 24 is fixed to the support body 21 of the replacement unit 2, first, the screw fixing part 73 a on the left side of the front face is fixed with the screw q, and then the main board fixing part 22 A from the back side of the support body 21. The screw fixing portion 73b on the right side of the front face is fixed by a screw Q through a through hole provided in the front. In the illustrated example, the screw q is fixed from the back side (main body 71 side) of the main board case 70, but the screw q may be fixed from the front side (case 72 side) of the main board case 70. Good.

Since it is formed in this way, the assembly of the main board 24 and the mounting to the support 21 are performed in parallel, so that the mounting operation can be performed efficiently and the replacement unit 2 must be removed from the housing 1. The main substrate 24 can be prevented from being removed from the support 21.
Incidentally, the main board 24 can be used in common with pachinko gaming machines by exchanging the chips mounted on the internal printed board, but this is the second embodiment. State.
(Upper door 30)
The upper door 30 is a plate-like door for closing the upper opening portion 13 of the housing 1, and is formed on the side plate 16 of the housing 1 so as to be rotatable and lockable. As shown in FIG. 1, an upper panel 34 having a symbol display window 31 through which the symbol of the rotary reel 23 can be seen from the front side is provided at a substantially central portion. In addition, a liquid crystal display device 32 is provided above the symbol display window 31 for displaying various effects by moving images and the like, and around the upper panel 34, a decorative portion 33 including electric decorations such as a lamp. Is provided.

When the upper door 30 is closed, it is automatically locked by a latch lock provided on the opposite side of the hinge 19, and the upper opening 13 of the housing 1 is sealed. Further, while the lower door 40 is released, the upper door 30 is unlocked by lowering a release knob provided below the upper door 30 (not shown).
Note that the upper door 30 can be adapted to different models by exchanging the upper panel 34. That is, the effect display units such as the main body of the upper door 30 and the liquid crystal display device 32 can be left in the housing 1 when changing models. Further, when the front design of the upper door 30 is changed by changing the model, it can be removed from the housing 1 and replaced with a new upper door 30.

(Lower door 40)
The lower door 40 is a door that is wider and thicker than the upper door 30 that is pivotally supported by the hinge 19 of the housing 1, and the upper portion of the lower door 40 operates the slot machine S as shown in FIG. It is a counter-like operation unit 41 for making it happen. In addition, a lower plate 46 that can store medals paid out from the hopper unit 5 is formed at the lower portion of the lower door 40, and between the lower plate 46 and the operation unit 41, the game content A lower panel 47 for other display is fitted.
As the operation unit 41, a medal slot 42 and a bet switch 43 provided on the left side of the upper surface are provided at the upper right end of the lower door 40, and a start switch 44, a stop switch 45, and a key hole 40A are provided on the front side. The bet switch 43 is for replacing the stored medal with medal insertion, and the start switch 44 and the stop switch 45 are for starting and stopping the rotation of the rotary reel 23. The keyhole 40A is for unlocking the lower door 40.

In the slot machine S, the operation of the start switch 44 is enabled by inserting medals or the operation of the bet switch 43, and the rotation of the rotary reel 23 is started by the operation of the start switch 44. When the lottery result of the winning determination performed by the main board 24 wins a predetermined winning combination, the rotary reel 23 can be stopped by operating the stop switch 45 so that the winning symbol becomes a winning mode. In this way, a medal is paid out from the hopper unit 5 and an advantageous game such as a bonus game is started.
Further, as shown in FIG. 2, a medal selector 48 is provided on the back side of the lower door 40 to determine whether a medal is correct or not while guiding the medal inserted from the medal insertion slot 42. When the lower door 40 is closed, it is automatically locked by a latch lock, and the opening lower part 14 of the housing 1 is sealed. Also, when a predetermined key is inserted into the keyhole 40A and turned, the lock of the lower door 40 is released, and the lock of the upper door 30 can be released by releasing the lower door 40.

The lower door 40 can be adapted to different models by exchanging the lower panel 47. That is, the lower door 40 main body can be left in the housing 1 when changing models. Further, when the lower door 40 main body is damaged or when the form of the operation unit 41 is changed due to a model change, the lower door 40 can be removed from the housing 1 and replaced with a new lower door 40.
(Removal of exchange unit 2)
Next, a procedure for attaching and detaching the exchange unit 2 in the slot machine S having the above configuration will be described.
Here, in a state where the replacement unit 2 is housed and fixed at a fixed position of the housing 1, as shown in FIG. 5, the IO board 60 is located in the space 22C of the support 20, and the main board is fixed. The main board 24 fixed to the portion 22A is on the front side of the slide member 50 and is in a position parallel to the IO board 60. The IO board connector 60A and the main board connector 24A are in a coupled state (see FIG. 12B). Further, as shown in FIG. 3, the housing connector 80 and the replacement unit connector 90 are coupled, and as shown in FIG. 6B, the sub reel board 27 is connected to the sub housing board 62 and the boards. Yes. That is, the sub reel substrate 27 and the sub housing substrate 62 are provided with connectors 27A and 62A (see FIG. 13B), and these are coupled. In this state, the replacement unit 2 is locked to the housing 1 by a predetermined fixing device (not shown), and the movement to the near side is restricted by the coupling of the IO board connector 60A and the main board connector 24A. Has been.

  First, when removing the exchange unit 2 fixed to the housing 1, the IO board 60 is slid rightward in FIG. As a result, the IO board connector 60A and the main board connector 24A are disconnected (see FIG. 12A). Next, when the fixing of the fixing device that fixes the replacement unit 2 and the housing 1 is released (for example, the clip is removed) and the replacement unit 2 is pulled out to the front side, the housing connector 80 and the replacement unit connector 90 are connected. The coupling and the coupling between the sub reel substrate 27 and the sub housing substrate 62 are released (see FIG. 6A). Since the housing connector 80 and the replacement unit connector 90 and the sub reel substrate 27 and the sub housing substrate 62 are coupled in the front-rear direction, the coupling unit 2 is pulled out and the coupling is released at the same time. Then, the replacement unit 2 can be taken out from the upper opening portion 13 of the housing 1.

In this way, the replacement unit 2 can be removed from the housing 1 without releasing any troublesome harness by simply releasing the fixing device and sliding the IO board 60.
On the other hand, when the replacement unit 2 is housed and fixed in the housing 1, first, the IO board 60 is positioned as shown in FIG. 12A (the space necessary and sufficient for the main board 24 to be located at the left end of the slide member 50. The replacement unit 2 is pushed into the upper portion 13 of the opening. When the replacement unit 2 is pushed into a fixed position, the housing connector 80 and the replacement unit connector 90, and the sub reel substrate 27 and the sub housing substrate 62 are matched and joined (see FIGS. 3 and 6B). ). At this time, the IO substrate 60 is positioned in the space 22C of the support 21 and is in parallel with the main substrate 24. Therefore, the IO board 60A and the main board connector 24A are coupled by sliding the IO board 60 leftward in FIG. 5 (see FIG. 12B). By this connection, the movement of the exchange unit 2 in the front-rear direction is restricted. Thereafter, if the replacement unit 2 is locked to the housing 1 by a predetermined fixing device, the replacement unit 2 is securely fixed to the housing 1.

Thus, even when the replacement unit 2 is housed and fixed in the housing 1, it is not necessary to perform any troublesome harness attachment work.
Unlike the connection between the housing connector 80 and the replacement unit connector 90, the IO unit 60 is manually moved after the replacement unit 2 is housed in a fixed position to connect the IO substrate connector 60A and the main substrate connector 24A. Therefore, there is no possibility that the connector part will collide and be damaged when the replacement unit 2 is pushed in. This is because when connecting the main board 24, which is an important board, directly, it is considered that such a stepwise connection is preferable, and it is not necessary to form a sturdy connector part on the board cases 70 and 74. It is based on good things.

(Board connection between case 1 and replacement unit 2)
The connection between the control board of the casing 1 and the exchange unit 2 of the slot machine S formed as described above will be described in comparison with the case of the conventional slot machine.
FIG. 13A is a schematic block diagram showing components and board connections of the casing 1 and the exchange unit 2 in the conventional separation type slot machine. Here, “door overflow” in FIGS. 13A and 13B is provided in an opening / closing sensor for detecting opening / closing of the front door 3 and a sub tank in which medals overflowing from the hopper unit 5 are stored. The “lower substrate” is a relay substrate for controlling the operation of the hopper unit 5. The “external concentration terminal board” is used for communication with the hall computer in the game hall. In the figure, a thick arrow indicates power supply, and a thin arrow indicates signal output.

In the conventional separation type slot machine, a main housing substrate 610 that is a relay substrate with the power supply unit 4 and the lower substrate is provided on the housing side, and a housing connector 80 is provided on the main housing substrate 610. It was done. On the replacement unit 2 side, a main board 240 and a sub board 260, and a main reel board 250 as a relay board are provided, and an exchange unit connector 90 is provided on the main reel board 250. The electrical connection between the housing 1 and the replacement unit 2 is performed between the boards by connecting the housing connector 80 and the replacement unit connector 90.
However, the conventional main board 240 also serves as input / output means (corresponding to the IO board). The input / output means simply relays the exchange of signals and does not depend on the slot machine model, and can be used in common with all models. It was useless to do.

  On the other hand, in the slot machine S according to the present embodiment, as shown in FIG. 13B, the IO substrate 60 is arranged on the housing side, and the main housing substrate 61 that is a relay substrate has the IO substrate 60 mounted thereon. And connected to a power supply unit, a lower substrate, and the like. Then, electrical connection between the housing 1 and the replacement unit 2 is performed between the boards by connecting the housing connector 80 and the replacement unit connector 90, and the IO board 60 and the main board 24 are connected to the IO board connector 60A and the main board. The sub housing substrate 62 and the sub reel substrate 27 are directly connected by the connector 24A, and the sub housing substrate connector 62A and the sub reel substrate connector 27A are directly connected. In this embodiment, since the upper door 30 is left in the housing 1 when the surface is changed, the sub display board 26 is provided in the effect display unit such as the liquid crystal display device 32 provided on the upper door 30. Is output via the IO substrate 60.

Further, since the main board 24 and the main reel board 25, and the main board 24 and the sub board 26 are connected via the IO board 60, the main board 24 is connected to the main reel board 25 and a signal. There is no need to provide input / output means for exchange and output means for outputting a signal to the sub-board 26. For this reason, the main substrate 24 can be reduced in size as compared with the conventional one. Further, since it is not necessary to provide a harness for connecting the main board 24 and the main reel board 25 and the main board 24 and the sub board 26 in the exchange unit 2, the harnesses attached to the exchange unit 2 are minimized. be able to.
Thus, according to the present embodiment, the number of parts involved in the replacement can be reduced as much as possible to reduce the replacement cost.

Further, in the present embodiment, in addition to the above, as shown in FIG. 12, the connection between the IO board 60 and the main board 24 intersects with the attaching / detaching direction (front-rear direction) of the replacement unit 2 (left-right direction). Since the IO substrate 60 is slidably formed, the replacement unit 2 cannot be pulled out to the near side unless the IO substrate 60 is moved. That is, the IO board 60 itself functions as a means for locking (or temporarily fixing) the replacement unit 2.
Therefore, for example, even if a fixing device for fixing the replacement unit 2 and the housing 1 is formed more easily than the conventional one, or a temporary fixing mechanism for assisting fixing with the fixing device is not provided. In addition, since the replacement unit 2 can be securely fixed to the housing 1, it is possible to reduce the number of parts and the manufacturing cost, and also to simplify the process of attaching and detaching the replacement unit 2. .

Further, in the present embodiment, the main board 24 is formed so as to be fixed from the back side of the support 21, so that the replacement unit 2 needs to be taken out of the housing 1 in order to remove the main board 24. The IO board 60 is positioned on the back side of the replacement unit 2 and has a structure that cannot be taken out unless the slide member 50 is removed from the housing 1. Since the main board 24 and the IO board 60 are formed in this way, the crime prevention effect is enhanced with respect to the so-called board exchange goto that changes the game setting illegally by replacing the board with an illegal board.
In the present embodiment, the IO substrate 60 is slid to be connected to the main substrate 24. Conversely, the main substrate 24 is formed to be slidable to the left and right, and the main substrate 24 is slid. Then, it may be connected to the IO substrate 60.

Specifically, a locking portion similar to the locking portion 52 of the slide member 50 is provided on the main substrate fixing portion 22A of the support 21, and a rail portion 79 provided on the upper and lower ends of the outer case of the main substrate 24 ( 20) and the locking portion can be engaged so that the rail portion 79 slides along the groove inside the locking portion. Even when formed in this way, the main board 24 cannot be taken out to the front side, and even if it is taken out in the left-right direction, it collides with the IO board 60 and the side plate 16 of the housing 1 and the rail part 79 and the locking part Since the engagement cannot be released, it is necessary to remove the replacement unit 2 from the housing 1 in order to remove the main board 24.

The ball passage 150 has a ball receiving opening that opens upward, and the game balls received and taken in from the ball receiving hole pass through the ball counter based on a predetermined winning signal, and are paid out to the ball tray 130 as a payout ball. . The non-exchange control unit 6 is a control board that is fixed to the main body frame 100 among the control boards that control the operation of the pachinko machine P.
Here, as the non-exchange control unit 6, at least a main frame board 210, a sub frame board 211, a payout control board 220, and an IO board 60 are provided (see FIG. 21B). The main frame substrate 210 is a substrate for performing control such as operation control of a ball launcher, and the sub frame substrate 211 is an effect device (for example, a lamp or a speaker) provided around the ball tray 130 or on the front door 8B. ) To control the operation. The payout control board 220 is for performing payout control of payout balls.

The IO board 60 is a control board for controlling the input / output of electric signals between the components arranged in the game board unit 9 and the components arranged in the main body frame 100. The configuration is almost the same as that described in the embodiment. In the present embodiment, as shown in FIG. 19, the IO board 60 is parallel to the main board 24 provided on the back surface of the game board unit 9 when the game board unit 9 is mounted on the main body frame 100. As in the first embodiment, the main board 24 and the boards are formed so as to be connectable to each other.
In the present embodiment, the IO board 60 is fixed to the inner frame 120 of the main body frame 100, and the IO board 60 does not move. Therefore, the rail portion 77 (see FIG. 8) is not formed on the IO substrate 60 in the present embodiment. Further, the position where the IO board connector 60A is formed is different from that according to the first embodiment.

The inner frame 120 is normally locked to the outer frame 110 in a closed state. When the game board unit 9 is replaced when changing the face, the inner frame 120 is opened, the game board unit 9 is unlocked from the back side of the inner frame 120, and the main body frame 100 is deferred to the island facility of the game hall. It is like that.
(Door unit 8)
The door unit 8 is a door body which is attached to the main body frame 100 and closes the inner frame opening 121 so as to be freely opened and closed, and has an attachment frame 8A, a front door 8B and a glass frame 8C as shown in FIG. Yes.
As shown in FIG. 17, the attachment frame 8A is a rectangular frame having an opening at the center, and is formed so as to be housed inside the inner frame opening 121 of the main body frame 100. A game board unit 9 is attached to the opening of the attachment frame 8A (see FIG. 18), and the inner frame opening 121 is closed by the game board unit 9.

Further, as shown in FIG. 14, the front door 8B is a door provided with a display device such as a decorative part and a lamp on the front side, and can be rotated in the horizontal direction via a shaft support part on the mounting frame 8A. It is attached. An opening window is formed in the center of the front door 8B so that the board surface 9A of the game board unit 9 can be seen from the front side. The glass frame 8C is formed so as to close the opening window from the inside. Has been.
The glass frame 8C has a transparent panel made of glass or the like fitted into the frame body, and is attached to the rear surface of the front door 8B or the attachment frame 8A so as to be rotatable in the horizontal direction via a shaft support portion.
The door unit 8 is attached to the main body frame 100 by storing and fixing the attachment frame 8A inside the inner frame opening 121. Further, the door unit 8 can be left in the main body frame 100 when the pachinko machine P is replaced. And when changing the front design of the pachinko machine P, the door unit 8 can be removed from the main body frame 100 and replaced with a new door unit 8.

(Game board unit 9)
The game board unit 9 is a main game apparatus of the pachinko machine P, and is a plate member having a board surface 9A in which a plurality of nails (not shown) are driven on the front side, as shown in FIG. Around the board surface 9A, there is provided a rail 9B for guiding the game ball launched from the ball launching device by operating the handle 140 to the game area, and at the center of the game area of the board surface 9A, A display unit 9E is provided for performing various displays such as characters, graphics, and moving images using a liquid crystal display device and a rotating reel. A start winning opening 9C called a start chucker is provided below the display unit 9E, and a winning opening 9D called an attacker is provided below the start winning opening 9C. The pachinko machine P is awarded when a ball enters the start winning opening 9C, and becomes a so-called “hit” by clearing a predetermined condition. The winning opening 9D is opened in this jackpot state.

  Further, as shown in FIGS. 18 and 19, an exchange control unit 7 composed of a control board fixed to the game board unit 9 is provided on the back surface of the game board unit 9. As shown in FIG. 21B, the exchange control unit 7 includes at least a main board 24, a sub board 26, and a panel surface control board 270. The main board 24 includes a ROM and a RAM centered on the CPU, and is a board for performing all control related to the game, such as lottery for determining the winning, operation of the winning opening 9D, etc. It is a board | substrate for performing the control of the production accompanying a game based on the output signal. Further, the board surface control board 270 is for controlling the operation of movable bodies such as the lighting / flashing of LEDs provided on the board surface 9A and the winning hole 9D based on the output signal from the sub board 26.

The main board 24 and the sub board 26 are different for each model, and the game contents and the accompanying effects are changed by changing these. Then, by exchanging the game board unit 9, the software part (main board 24 etc.) and the hardware part (board surface 9A, display part 9E etc.) for playing the game are exchanged at the same time.
Here, the main board 24 has a configuration similar to that of the main board 24 described in the first embodiment, and is attached to the printed board 24B (see FIG. 11) housed in the main board case 70. An IC chip for a gaming machine is mounted. As shown in FIG. 19, the main board 24 is formed to be slidable in the left-right direction by a slide member 50 ′ provided on the back surface of the game board unit 9. Then, by connecting the main board connector 24A provided on the side surface portion with the IO board connector 60A provided on the IO board 60, the IO board 60 and the boards can be connected to each other.

As shown in FIG. 20, the slide member 50 ′ in the present embodiment has substantially the same configuration as the slide member 50 described in the first embodiment, and the main board case 70 of the main board 24 has the same structure. The rail portion 79 formed on the upper and lower end portions is engaged with the locking portion 52 of the slide member 50 ′ so that the rail portion 79 slides along the groove portion 53 and the main board 24 is attached. The main board 24 is attached to the game board unit 9 by fixing the slide member 50 ′ to the game board unit 9.
Here, the distance between the screw holes 54a, 54b formed in the mounting portion 54 of the slide member 50 ′ is shorter than the lateral width of the main board case 70, and as in the first embodiment, When the main board case 70 is attached to the slide member 50 ′, the screw holes 54a and 54b on both sides are not exposed to the front side at the same time.

Further, as shown in FIG. 19, a stopper T is provided on the back surface of the game board unit 9 for restricting the movement distance when the main board 24 slides to the opposite side of the IO board 60 to a certain level. The main board 24 collides with the IO board 60 when it is slid to the right side in FIG. 19, and hits the stopper T when it is slid to the left side, so that it cannot be removed from the slide member 50 ′. In other words, the main board 24 cannot be removed from the slide member 50 ′ unless the slide member 50 ′ is removed from the game board unit 9.
Although not particularly illustrated, in the above, when the main board 24 is moved to the left and right as much as possible, the screw holes 54a and 54b of the slide member 50 ′ are exposed to the front side one by one. Therefore, even if the stopper T is provided, it is possible to remove the slide member 50 ′ from the game board unit 9.

As shown in FIG. 18, the game board unit 9 is housed in the inner frame opening 121 of the main body frame 100 to which the door unit 8 is attached from the front side. Then, it is fixed from the back side of the main body frame 100 by a fixing device (not shown) such as a clip. When changing the model, the game content is changed by exchanging at least the game board unit 9, and the main body frame 100 and the door unit 9 can be used as they are as a new game machine.
(Removal of game board unit 9)
Next, a procedure for attaching and detaching the game board unit 9 in the pachinko machine P formed as described above will be described.

Here, in a state where the game board unit 9 is housed and fixed at a fixed position of the main body frame 100, the main board 24 is in a position parallel to the IO board 60 as shown in FIG. The IO board connector 60A and the main board connector 24A are in a coupled state. In this state, the game board unit 9 is locked to the main body frame 100 by a predetermined fixing device (not shown), and is coupled to the IO board connector 60A and the main board connector 24A in the front-rear direction (inner frame 120). Movement in a direction perpendicular to the front of the head is restricted.
When removing the game board unit 9 fixed to the main body frame 100, first, the inner frame 120 is opened with the door unit 8 attached to the inner frame 120 (see FIG. 16). Expose the back side. Next, the main board 24 is slid leftward in FIG. 19 to disconnect the IO board connector 60A from the main board connector 24A. Next, the fixing device that fixes the game board unit 9 and the main body frame 100 is released (for example, the clip is removed), the front door 8B and the glass frame 8C are opened, and the game board unit 9 is moved to the front side. Just pull it out.

In this way, the game board unit 9 can be removed from the main body frame 100 by simply releasing the fixing device and sliding the main board 24 without performing any troublesome harness removal work.
On the other hand, when the game board unit 9 is housed and fixed in the main body frame 100, first, the main board 24 is positioned at the position indicated by the two-dot chain line in FIG. 19 (the left end of the main board 24 abuts against the stopper T and the game board unit 9 is moved from the right end of the main board 24 to the position where the right end of the main board 24 does not protrude), and the front board 8B and the glass frame 8C are opened to the mounting frame 8A of the door unit 8 from the front side. Is inserted (see FIG. 18). When the game board unit 9 is pushed into a fixed position, the replacement control unit 7 on the back side of the game board unit 9 projects from the opening of the mounting frame 8A and the inner frame opening 121 to the back side of the main body frame 100, and the main board. 24 is in parallel with the IO substrate 60. Therefore, the IO board connector 60A and the main board connector 24A are coupled by sliding the main board 24 in the right direction in FIG. By this connection, the game board unit 9 is restricted from moving in the front-rear direction (particularly forward). Thereafter, the game board unit 9 is locked to the main body frame 100 by a predetermined fixing device.

In this way, even when the game board unit 9 is housed and fixed in the main body frame 100, it is not necessary to perform any troublesome harness installation work.
(Board connection between main frame 100 and game board unit 9)
A connection mode of the control board of the main body frame 100 and the game board unit 9 of the pachinko machine P formed as described above will be described in comparison with a conventional game machine.
FIG. 21A is a schematic block diagram showing the main body frame 100 and the component parts of the game board unit 9 and the board connection of the replacement control unit 7 in a conventional pachinko gaming machine. Here, in FIGS. 21A and 21B, “door / dish” refers to an open / close sensor for detecting the opening / closing of the front door 8B and an overflow sensor provided in the ball tray 130 (both not shown). ). In the figure, thick arrows indicate power supply, and thin arrows indicate signal output.

  In a conventional pachinko machine, a power source 200, a main frame board 210, a sub frame board 211, and a payout control board 220 are provided on the main body frame side, and a main board 241 and a sub board 261 are provided on the game board unit side. In addition, a board surface control board 270 is provided. Then, the electrical connection between the main body frame and the game board unit is performed by connecting the harness. That is, a harness for supplying power to the panel control board 270, a harness for supplying power to the main board 241, a harness for sending signals from the door / dish sensor to the main board 241, and a main frame from the main board 241 The harness for sending signals to the board 210 and the harness for exchanging signals between the sub board 261 and the sub frame board 211 are connected to and disconnected from the electrical signals by connecting and releasing the connectors provided in the middle. It was supposed to be.

Therefore, in conventional pachinko machines, when replacing the board surface, the harness must be removed at least five places before removing the game board unit, and the harness must be attached even after the game board unit is installed. The replacement work took time and put a burden on the workers. Further, there is a risk that the harness may be erroneously connected or forgotten to be connected, or the harness may be caught between the main body frame and the game board unit when the game board unit is pushed into the main body frame.
On the other hand, in the pachinko machine P according to the present embodiment, as shown in FIG. 21B, the IO board 60 is arranged on the main body frame side, and the IO board 60 is connected to the power source 200, the main frame board 210, and the like. It is connected. In addition, the sub board 26 and the board surface control board 270 of the game board unit 9 are supplied with power via the main board 24. The IO board 60 and the main board 24 are formed to be directly connected by the IO board connector 60A and the main board connector 24A.

Therefore, according to the present embodiment, when the game board unit 9 is attached / detached, it is not necessary to connect and disconnect the connectors at several places, and the replacement work can be performed quickly. Further, since the connection harness is not exposed on the back side of the game board unit 9, the harness is not bitten when stored in the main body frame 100.
Further, in the present embodiment, the connection between the IO board 60 and the main board 24 is set in a direction (left / right direction) intersecting with the attaching / detaching direction (front / rear direction) of the game board unit 9 and the main board 24 is slidable. Thus, the game board unit 9 cannot be pulled out to the near side unless the main board 24 is moved. That is, the main board 24 itself also functions as a means for locking the game board unit 9, so that, for example, a fixing device for fixing the game board unit 9 and the main body frame 100 can be formed more easily than the conventional one. However, the game board unit 9 can be securely fixed, the number of parts and the manufacturing cost can be reduced, and the process of attaching and detaching operations can be simplified.

In addition, in this embodiment, since the slide member 50 ′ has to be removed from the game board unit 9 in order to remove the main board 24, the crime prevention effect is enhanced against the board exchange goto. .
In the present embodiment, the main board 24 is slid to be connected to the IO board 60. Conversely, the IO board 60 is slidable to the left and right, and the IO board 60 is slid. In this case, the main board 24 may be connected.
Specifically, although not particularly illustrated, a slide member 50 ′ is attached to the back side of the inner frame 120, and rail portions similar to those provided on the main board 24 are provided on the upper and lower ends of the exterior case of the IO board 60. The rail portion can be formed so that the rail portion slides along the groove portion 53 by engaging the engaging portion 52 of the slide member 50 ′ with the rail portion. Also in this case, similarly to the main board 24 described above, the IO board 60 cannot be taken out unless the slide member 50 ′ is removed from the inner frame 120. Thus, when the IO board 60 is made slidable, there is an advantage that the work is simple when the main board 24 is attached to the game board unit 9.

As described above, according to the present invention, the input / output means that has been conventionally arranged on the separation unit side, particularly the main substrate, is unnecessary, and the main substrate 24 arranged on the separation unit side is reduced in size so that the replacement cost can be reduced. It can be reduced as much as possible, and the separation unit can be replaced easily. In particular, in the pachinko machine P, when attaching / detaching the main body frame 100 and the game board unit 9, it is not necessary to attach / remove the harness, which speeds up the operation and at the same time, attaches the harness when attaching the game board unit 9. There is no need to misconnect or forget to connect, and the installation work can be completed reliably.
Further, since the connection direction of the IO substrate 60 and the main substrate 24 is set to intersect with the mounting direction of the separation unit to the main body, the separation unit is accommodated and installed in the main body, and the IO substrate 60 and the main substrate 24 are installed. When is connected, the separation unit is locked to the main body. For this reason, it is possible to simplify the fixing device for fixing the separation unit to the main body, and to reduce the number of attachments. As a result, the number of parts of the main body and the separation unit can be reduced. .

  In the above embodiment, the IO substrate 60 or the main substrate 24 is formed to be slidable in the left-right direction. However, in the present invention, the IO substrate 60 or the main substrate 24 is slidable in the vertical direction. May be. For example, in FIG. 19, the IO board 60 is disposed below the main board 24, the main board connector 24A is formed at the lower end of the main board 24, and the IO board connector 60A is formed at the upper end of the IO board 60. In addition, a slide member 50 ′ is provided that allows either the IO board 60 or the main board 24 to slide up and down. Even if formed in this way, the IO board 60 and the main board 24 are connected to restrict the movement of the game board unit 9 in the attaching / detaching direction (front-rear direction).
