DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board case for a game circuit board incorporated in a game machine such as a slot machine or a pachinko machine.

[0002]

2. Description of the Related Art As a gaming machine in a game arcade, there is, for example, a slot machine or a pachinko machine. In the case of a slot machine, for example, this is a game in which a player operates a rotating reel, and the three reels are rotated simultaneously or individually, and then displayed on the reel when stopped. It is a game machine for enjoying the success or failure of the required combination of the designated patterns.

In FIG. 15, reference numeral 10 denotes a slot machine. As shown in the figure, the slot machine 10 has a box-shaped housing 11. A rectangular window-shaped display window 12 facing the player is formed at the center and upper part of the housing 11. At the center of the display window 12 at the center, a symbol display window 13 through which symbols 61 of the three reels 40 can be seen is formed. A control device 100 for controlling the entire operation of the slot machine 10 is built in the slot machine 10.

[0004] When playing a game in a slot machine, a special coin to be rented in a game hall is inserted into a slot of the machine, and then the reels are rotated through operating tools such as a lever 30 for rotating three reels. The rotation of the individual reels is stopped via the means 50 for stopping the rotation, and coins are obtained according to the combination of the picture patterns of the reels at the time of the stop.

[0005] Most of such gaming machines installed in game arcades, such as slot machines, include control of the mechanism of each part, probability of winning (for a slot machine, probability of establishment of the above-mentioned effective combination), and the like. The entire control is performed under the control of a computer in the control device 100.

For this reason, a gaming machine using a computer has a control circuit board incorporating a CPU constituting a microcomputer and a memory such as a ROM. The ROM stores a program for controlling the operation. Such a board is attached inside the game machine main body as shown in FIG. A game machine equipped with such a substrate is shipped from a game machine manufacturer, delivered and installed in a game room, and provided for the above-mentioned services in the game room.

This type of gaming machine is subject to certain legal regulations,
It is also subject to inspection by the competent authority. At that time, it is also checked whether the ROM storing the program has been exchanged improperly. If the program is rewritten, coins may be paid out beyond the legally permitted limit.

[0008] In order to protect security against various types of tampering with the main board case used in the slot machine, a safety lock system for the main board case is adopted. The conditions for the safety lock method of the main board case are as follows. (1) For the main board part housed in the main board case,
The structure cannot be touched unless the safety lock attached to the resin case is broken or opened. (2) When the main board case is once safety-locked and attached to the main body of the game machine, the main board case is designed so that it cannot be taken out of the main body of the game machine unless the safety lock is broken. (3) The safety lock system is selected from the following two basic structures. A Integrated type that seals the main board case and fixedly seals to the game machine body together a Separate type that seals the main board case and fixedly seals to the game machine body separately (4) Opening and sealing the safety lock In this case, no special tool is required, as it can be performed using a nipper or a + or-driver. (5) The detent screws, pins, etc. used for the safety lock must be structured so that once locked, they cannot be easily removed unless they are damaged. (6) Attach the safety lock use recording paper to an easy-to-see place on the main board case so that the record can be recorded when the safety lock is used, so that the record remains when used.

By adopting a safety lock system satisfying such conditions, fraudulent acts can be eliminated. FIG. 16 shows a control device 100 including a main board case of this type of safety lock system.

The control device 100 shown in FIG. 16 includes a resin case main body 3 for fixing the main board 4 and a resin case upper lid 2 for sealing the main body. The control device 100 is fixed to the caulking / sealing fixture 5 attached to the main body of the gaming machine by a detent screw 103 at a projecting portion of the resin case upper lid 2. The detent screw 103 is a special screw that can be tightened but cannot be loosened. Since the protruding portion is formed integrally with the resin case upper lid 2, the case cannot be removed unless this portion is cut.

In the case of the main board case of FIG. 16, the sealing is performed as follows.

First, with the main board 4 attached, the resin case upper lid 2 is attached to the resin case main body 3 with screws 101a and 102a. Thereby, the main substrate 4 is sealed. Since the screws 101a and 102a cannot be loosened, it becomes impossible to separate the resin case upper lid 2 and the resin case main body 3.

Next, the control device 100 is caulked with the screws 101b and 102b and screwed to the sealing and fixing metal fitting 5, and
Attached to the housing of the gaming device. Screw 101b, 102b
Cannot be loosened, and it becomes impossible to remove the control device 100.

At the time of on-site inspection by the competent government office, or when the control device 100 is unavoidably removed due to a failure or the like, the portion indicated by the mark in FIG. That is, when removing the control device 100, the protrusions of the resin case upper lid 2 at the screws 101b and 102b are cut at the marked portions. When removing the resin case upper cover 2, the screws 101a,
Cut the same part of 102a.

According to the main board case shown in FIG. 16, normally, the control device 100 and the case 2 cannot be removed. The case can be removed by destroying the projection, but in that case, the trace always remains, and even if someone opens the case illegally, it can be easily found.
Therefore, the main board case of FIG. 16 satisfies the above conditions.

[0016]

Although the main board case of FIG. 16 satisfies the condition of safety lock, it has a problem in effective use of resources. The main board case shown in FIG. 16 is provided with spare screws 101c to 101e and 102c to 102e in advance, and the safety lock can be released up to three times under appropriate management to perform inspection and maintenance of the main board. But,
Beyond that, the main board case can no longer be used. Although the main part of the main board case can be reused, there is also a problem that the main board case cannot be reused because all the protruding parts for the safety lock are cut off. From the viewpoint of reuse, it is not good to destroy the board case body in the first place.
Eventually, the main board case becomes waste, which goes against recent demands for protection and ecology of the global environment.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has as its object to provide a circuit board case that can be reused while satisfying the conditions of the safety lock.
