TECHNICAL FIELD OF THE INVENTION
The present invention relates to a circuit board case for a game circuit board built in a game machine such as a slot machine and a pachinko machine.
[0002]
[Prior art]
As a gaming machine in a game arcade, for example, there is 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 after rotating three reels simultaneously or individually, the reel is displayed on the reel when stopped. It is a game machine for enjoying the success or failure of a required combination of the designated patterns.
[0003]
In FIG. 15, reference numeral 10 denotes a slot machine. As shown in the figure, the slot machine 10 has a rectangular box-shaped housing 11. A rectangular window-like display window 12 facing the player side 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 lent out at 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. Is stopped via means 50 for stopping the rotation of the reels, and coins are obtained according to the combination of the reel patterns at the time of the stop.
[0005]
Most of such gaming machines installed in game arcades, such as slot machines, control the entire game machine, including controlling the mechanisms of each unit and processing the winning probability (for slot machines, the probability of establishing the above-mentioned effective combinations). Is performed under the control of the computer in the control device 100.
[0006]
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 provided 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.
[0007]
This type of gaming machine is subject to certain legal regulations and is 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 legal 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 method of the main board case is adopted. The conditions for the safety lock method of the main board case are as follows.
(1) The main board portion housed in the main board case must be of a structure that 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 game machine main body, the main board case is configured to be absolutely unremovable from the game machine main body unless the safety lock is broken.
(3) The safety lock method is selected from the following two basic structures.
A. Integrated type that seals the main board case and fixedly seals the game machine body together. A. Separate type that seals the main board case and fixedly seals the game machine body separately. (4) Opening / 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 screw, pin, etc. used for the safety lock must have a structure that, once locked, cannot be easily removed unless it is 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.
[0009]
By adopting the safety lock method that satisfies such conditions, it is possible to eliminate fraud. FIG. 16 shows a control device 100 including a main board case of this type of safety lock system.
[0010]
The control device 100 of 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 game machine main body 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.
[0011]
In the case of the main board case of FIG. 16, sealing is performed as follows.
[0012]
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.
[0013]
Next, the control device 100 is swaged with the screws 101b and 102b to the fixing / fixing metal fitting 5, and attached to the housing of the gaming machine. Since the screws 101b and 102b cannot be loosened, the control device 100 cannot be removed.
[0014]
At the time of on-site inspection by the competent authority or when the control device 100 is unavoidably removed due to obstacles or the like, the portion marked in FIG. 16 is cut off to remove the control device 100 or to remove the resin case upper lid 2. 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 lid 2, the same part of the screws 101a and 102a is cut.
[0015]
According to the main board case of 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]
[Problems to be solved by the invention]
Although the main board case of FIG. 16 satisfies the condition of safety lock, there is 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. However, beyond that, the main board case can no longer be used. Further, although the main part of the main board case can be reused, there is also a problem that it 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 the recent demands for global environmental protection and ecology.
[0017]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a circuit board case that can be reused while satisfying the conditions of the safety lock.
