The screw fixing portion 73b on the front right side is fixed by a screw Q through a through hole provided in 22A. 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 common main substrate 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 is not removed from the housing 1. Thus, it is possible to prevent the common main substrate 24 from being removed from the support 21.
(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 common main board 24 wins a predetermined winning combination, the rotary reel 23 can be stopped by the operation of the stop switch 45 so that the winning symbol becomes a winning mode. If it is possible, a prize is won, and a medal is paid out from the hopper unit 5 or 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 common main board 24 fixed to the portion 22A is in front 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. 11B). 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. 12B), 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. 11A). 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 substrate 60 is necessary and sufficient to position the common main substrate 24 at the position shown in FIG. The IO unit 60 is moved to a position where the IO board 60 is slid so as to create a space, and the replacement unit 2 is pushed into the upper opening 13. 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 common 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. 11B). 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 common main board 24, which is an important board, directly, it is considered preferable to use such a stepwise connection, and it is necessary to form a sturdy connector part on the printed boards 24B and 60B. It is based on what is good.

(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. 12A is a schematic block diagram showing the 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. 12A and 12B is 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 exchange 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. 12B, the IO board 60 is arranged on the housing side, and the main housing board 61 that is a relay board has the IO board 60 mounted thereon. And connected to a power supply unit, a lower substrate, and the like. The housing 1 and the exchange unit 2 are electrically connected to each other by connecting the housing connector 80 and the exchange unit connector 90, and the IO board 60 and the common 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 substrate 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 common main board 24 and the main reel board 25, and the common main board 24 and the sub board 26 are connected via the IO board 60, the common main board 24 includes the main reel board 25. There is no need to provide input / output means for exchanging signals and output means for outputting signals to the sub-board 26. For this reason, the common 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 common main board 24 and the main reel board 25 and the common main board 24 and the sub board 26 in the exchange unit 2, the number of harnesses attached to the exchange unit 2 is minimized. Can be suppressed.
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. 11, the connection between the IO substrate 60 and the common main substrate 24 intersects with the attachment / detachment direction (front-rear direction) of the replacement unit 2 (left-right direction). ) And the IO substrate 60 is formed to be slidable, so that 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. .

Furthermore, in the present embodiment, the common main board 24 is formed so as to be fixed from the back side of the support 21. Therefore, in order to remove the common main board 24, it is necessary to take out the replacement unit 2 from the housing 1. is there. 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 it is formed in this way, the common main board 24 and the I / O board 60 have a crime prevention effect against the so-called board exchange goto that changes the game setting illegally by replacing it with an illegal board.
In this embodiment, the IO substrate 60 is slid to be connected to the common main substrate 24. Conversely, the common main substrate 24 is slidable to the left and right, and the common main substrate is formed. 24 may be slid to 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 the rail portion 79 provided at the upper and lower ends of the exterior case of the common main substrate 24. (See FIG. 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 common main board 24 cannot be taken out from the front side, and even if it is pulled 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. Therefore, it is necessary to remove the replacement unit 2 from the housing 1 in order to remove the common main board 24 .

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 common 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. 15). Expose the back side. Next, the common main board 24 is slid leftward in FIG. 18 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 without performing any troublesome harness removal work by simply releasing the fixing device and sliding the common main board 24.
On the other hand, when the game board unit 9 is housed and fixed in the main body frame 100, first, the common main board 24 is positioned at the position indicated by the two-dot chain line in FIG. From the right end of the panel unit 9 to the position where the right end of the common main board 24 does not protrude), and the front door 8B and the glass frame 8C are opened to the mounting frame 8A of the door unit 8 from the front side. The panel unit 9 is pushed in (see FIG. 17). 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 protrudes 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 common main unit The substrate 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 common main board 24 to the right 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. 20A is a schematic block diagram showing the main body frame 100 and the components of the game board unit 9 and the board connection of the replacement control unit 7 in a conventional pachinko gaming machine. 20 (A) and 20 (B), “door / dish” refers to an open / close sensor for detecting the opening / closing of the front door 8B and an overflow sensor provided on 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 substrate 210 and the harness for exchanging signals between the sub-board 261 and the sub-frame board 211 are connected / disconnected of electrical signals by connecting / disconnecting 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. 20B, the IO board 60 ′ is arranged on the main body frame side, and the IO board 60 ′ is used for the power source 200 and the main frame board 210. Etc. are connected. Further, the sub board 26 and the board surface control board 270 of the game board unit 9 are supplied with power via the common main board 24. The IO board 60 ′ and the common 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 common 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 common main board 24. Is formed to be slidable, so that the game board unit 9 cannot be pulled out to the near side unless the common main board 24 is moved. That is, since the common main board 24 itself also functions as a means for locking the game board unit 9, for example, a fixing device for fixing the game board unit 9 and the main body frame 100 is more easily formed than the conventional one. Even so, the game board unit 9 can be securely fixed, the number of parts and manufacturing costs can be reduced, and the process of attaching and detaching operations can be simplified.

In the present embodiment, the common 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 to form the IO board. 60 'may be slid to be connected to the common main board 24. Alternatively, the common main board 24 may be formed to slide up and down to connect to the IO board 60 ′, or the IO board 60 ′ may be formed to slide up and down to connect to the common main board 24. Also good.
As described above, according to the present invention, the common main board 24 arranged on the separation unit side can be reduced in size by replacing the input / output means conventionally arranged on the separation unit side, particularly on the main board, and replacing costs. As a result, the separation unit can be easily replaced. 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. There is no need to misconnect or forget to connect, and the installation work can be completed reliably.

In the present invention, since the common main board 24 is formed so that it can be used in common for both the slot machine S and the pachinko gaming machine P, the recyclability is further improved and the environmental load is reduced. This can also contribute to cost reduction for game machine replacement.
In the above-described embodiment, the case where the common main board 24 is used in common between the slot machine S and the pachinko gaming machine P has been described. However, the common main board 24 according to the present invention is a game other than the above. It can be used in common with other machines. For example, the present invention can be used for a parrot game machine that uses a pachinko ball as a game medium to play a game similar to a slot machine. In this case, the ROM for the parrot gaming machine and the CPU for the parrot gaming machine in which the program corresponding to the specific model of the parrot gaming machine is integrated with the printed circuit board 24B of the common main board 24 are formed into one chip. A parrot gaming machine chip may be attached and used.

Further, in the embodiment of the implementation described above, attachment and detachment of the common main substrate 24 or IO board 60, 60 'to the main part of the separation unit (exchange unit 2 and the game board units 9) (housing 1 and the main body frame 100) In the present invention, the main board connector 24A and the IO board connector 60A are attached to and detached from the separation unit, while the main board connector 24A and the IO board connector 60A are joined to each other. You may make it join to. In this case, the main board connector 24A and the IO board connector 60A can be formed to be joined by storing and installing the separation unit at a fixed position of the main body.
