The printed circuit board 24B is accommodated in the case by fixing the screw fixing portions 73 provided on the sides of the main body 71 and the cover 72 with screws Q and q, respectively.
Further, the main board 24 is assembled to the main board fixing portion 22A when the main body 71 and the cover 72 are fixed, and a screw is provided from the back side of the support 21 as shown in FIGS. 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.
(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. 13B). 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. 14B), 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 the replacement unit 2 fixed to the housing 1 is removed, a hand is inserted from the gap between the replacement unit 2 and the side plate 16 and 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. 13A). 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 placed at the position shown in FIG. 13A (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 connector 60A and the main board connector 24A are coupled by inserting the hand from the gap between the replacement unit 2 and the side plate 16 and sliding the IO board 60 leftward in FIG. 5 (see FIG. 13B). ). 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. 14A 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. 14A and 14B 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 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. 14B, 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. 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.
As described above, according to the present embodiment, the number of parts for replacement can be reduced as much as possible to reduce the replacement cost, and the harness attached to the replacement unit 2 can be attached to the interior of the housing 1 during the replacement work. Since it is not caught or pinched by the device, the working efficiency can be improved.

Further, in the present embodiment, in addition to the above, as shown in FIG. 13, the connection between the IO board 60 and the main board 24 intersects with the attaching / detaching direction (front-back 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 IO substrate 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 fixing portions 54 for fixing the slide member 50 are provided at two locations. However, if the fixing portions 54 are provided, for example, at four locations, the removal operation becomes more difficult. In addition, as shown in FIG. 15, the slide member 50 is divided into an upper slide member 50A and a lower slide member 50B, and the engaging portion 52 and the rail portion 77 are engaged or not engaged from the side of the slide member 50. The shape may be such that the engagement cannot be released (the rail portion 77 cannot be fitted or pulled out from the lower or upper opening of the locking portion 52). When formed in this way, the IO board 60 cannot be removed from the housing 1 unless both the upper slide member 50A and the lower slide member 50B are removed from the housing 1, and thus the IO board 60 is more difficult to take out. can do.
