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. 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 each provided with a connector (not shown), 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. 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 board 60 is placed at the position shown in FIG. 11A (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 a 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. 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 main board 24, which is an important board, directly, it is considered that such a stepwise connection is preferable. Even if a sturdy connector part is not formed on the printed boards 24B and 60B, It is based on good things.

As described above, according to the present embodiment, the main board 24 is located on the back side of the replacement unit 2 and can be taken out from the support 21 without removing the support fixing screw Q from the back side of the support 21. There is no structure. Since the main board 24 is formed in this way, the crime prevention effect is enhanced with respect to the so-called board exchange goto which changes the game setting illegally by replacing the main board 24 with an unauthorized board.
Further, in the present embodiment, in addition to the above, since the board portion related to the input / output control that is conventionally mounted on the main board 24 is left as the IO board 60 on the housing 1 side, the parts related to replacement It is possible to reduce the replacement cost by reducing the score as much as possible. In addition, since the main board 24 and the O board 60 can be connected to each other, the harness attached to the exchange unit 2 is not caught or caught between devices inside the housing 1 during the exchange work. Efficiency can be increased.

  In the present embodiment, the main board 24 and the IO board 60 are connected to each other so that the casing 1 and the exchange unit 2 are electrically connected, and the exchange unit 2 is locked by this board connection. However, the present invention can also be applied to a conventional slot machine in which a main board including an IO is mounted on an exchange unit.
