Therefore, it is possible to prevent a situation in which the control element is illegally replaced or remodeled from the gap between the upper cover 9 and the surface of the substrate 8. Further, such a fraud prevention effect becomes more reliable as the gap between the upper cover 9 and the surface of the substrate 8 becomes smaller.

[Embodiment 2] The control device 3b of the embodiment 2
Unlike the control device 3a according to the first embodiment, the upper cover 9 and the lower cover 10 are laid on the side surfaces of the screwed upper cover 9 and the lower cover 10 (portions of the upper fixed blade 13 and the lower fixed blade 26). In addition, as shown in FIG. 9, a model name, a manufacturer, and a serial number (that is, a serial number unique to the machine) are provided by a printing means (for example, a laser marker manufactured by Sunkus Co., Ltd.) using a laser beam (infrared CO ₂ laser). ,
Identification information 32 indicating the date of manufacture and the like is printed.
The other configuration of the control device 3b is the same as the configuration of the control device 3a.

As described above, the control device 3b displays the identification information so as to straddle the upper cover and the lower cover, so that not only the same effect as the control device 3a of the first embodiment can be exhibited, but also The cover 9 was incorrectly removed and the ROM
After 11 has been illegally replaced and modified, the lower cover 1
The remaining screw 19 is forcibly removed by a plier or the like, and another upper cover 9 'illegally obtained from another discarded control device 3b' (the screw holding portion 14 of the removed upper cover 9 after use). (The number of unused screw holding portions 14 ′ that is larger than the number of unused screw holding portions 14 ′) is screwed to the lower cover 10, and even if the upper cover 9 appears to be not removed at first glance, the upper cover 9 ′ is not removed. Of the identification information 32 ′ displayed on the lower cover 10 and the identification information 32 displayed on the lower cover 10.
Does not match, and a situation in which the upper cover 9 has been illegally removed can be quickly found. Therefore, it is possible to prevent a situation in which the illegal player operates conveniently with high accuracy.

Further, since the printing by the printing means using the laser beam has a unique form and color, the control device 3b is configured such that the regular upper cover 9 is removed, the ROM 11 is improperly replaced, and the ROM 11 is improperly modified. After that, another upper cover 9 ′ displaying false identification information 32 ′ similar to the regular upper cover 9 is screwed to the lower cover 10 by a method different from the printing means using laser light. However, it can be immediately recognized that the identification information 32 'is false, and the situation where the upper cover 9 has been illegally removed can be promptly detected.

It should be noted that the control device of the present invention is not limited to the above-described embodiment at all, and the shape, structure, mounting position, mounting method, etc. of the board, chassis, upper cover, and lower cover are not limited. Changes can be made as appropriate without departing from the spirit of the present invention.

For example, the number of screw holding portions provided on each of the left and right upper fixed wings of the upper cover and the number of mounting tabs provided on each of the right and left lower fixed wings of the lower cover are not limited to four. The number may be two or three, or may be five or more.

The positions of the upper fixed wing and the lower fixed wing are as follows.
It is not limited to the left and right edges of the upper and lower covers, but may be the upper and lower edges of the upper and lower covers.

Further, the one-way type screw is not limited to a wood screw having a sharp tip as in the above embodiment, but may be a screw having another shape such as a screw having a flat tip. When a screw having a flat tip is used, it is preferable that a screw groove is previously formed in the mounting tab of the lower cover.

When the identification information is displayed so as to straddle the upper cover and the lower cover, as a display method, in addition to a method of printing by a printing means using a laser beam, a method of printing by silk printing, Alternatively, a method of integrally forming identification information at the stage of manufacturing the package of the control element by injection molding or the like can be adopted.
In addition, when a method of printing by a printing unit using a laser beam or a method of printing by silk printing is adopted, there is an advantage that a serial number different from a control device of another game machine can be displayed.

In addition, when the identification information is displayed so as to straddle the upper cover and the lower cover, the identification information is limited to information indicating a model name, a manufacturer, a serial number, and a date of manufacture. Instead, it can be changed to indicate various other data. Furthermore, the position where the identification information is displayed is not limited to the side surfaces of the upper cover and the lower cover, but may be changed to the upper surface, the lower surface, or the like of the upper cover and the lower cover. In some cases, it is possible to set the position so that it cannot be directly viewed. When such a configuration is adopted, the fraud prevention performance of the control device becomes even more accurate.

On the other hand, when the identification information is printed so as to straddle the upper cover and the lower cover by the printing means using the laser light, other types of laser light besides the printing means using the infrared CO ₂ laser are used. It is also possible to use a printing means that utilizes a. Since the upper cover and the lower cover are usually formed of a hard synthetic resin,
When the identification information is printed by the printing means using the O ₂ laser, there is a merit that each character has a very clear outline and is easy to see.

The identification information displayed so as to straddle the upper cover and the lower cover can be changed to a code such as a bar code or a two-dimensional code (for example, a QR (quick response) code), or the like. It is also possible to change the display by code and the character display as in the above embodiment. Since the contents of the code cannot be recognized without a code reader, if the identification information is changed to the code display, the display of the incorrect identification information becomes more difficult, and the control device's fraud prevention performance becomes more accurate. There is also a merit that it becomes high.

In addition, in the above embodiment, the pachinko machine has been described, but the gaming machine of the present invention may be a gaming machine other than a pachinko machine such as a slot machine or a video game.

One is screwed to the lower cover with a one-way type screw, and in order to separate the upper cover from the lower cover, the screw holding part screwed to the lower cover must be cut from the upper cover If the upper cover is removed improperly, a trace will always remain. Therefore, it is possible to easily detect a fraudulent situation, and prevent a situation in which a fraudulent player operates conveniently. Nevertheless, since each screw holding portion is easily cut from the main body of the upper cover, the upper cover can be easily removed and the control element on the board can be easily checked.

In the control device according to the second aspect of the present invention, at each corner of the chassis, the board mounting portions are integrally protruded so as to exhibit high strength. The corners are screwed, and the board is covered by the upper cover without forming a gap between the board and the upper cover. Even when the screwing of the portion exposed to the outside of the cover is released, no gap is formed between the upper cover and the substrate surface. Therefore, it is possible to prevent a situation in which the control element is illegally replaced or remodeled from the gap between the upper cover and the substrate surface.

In the control device according to the third aspect of the present invention, since the identification information is displayed so as to straddle the upper cover and the lower cover, the upper cover is illegally removed, and the built-in control element is illegally replaced and illegally modified. After that, another upper cover is screwed to the lower cover, and even if the upper cover does not seem to be removed at first glance, part of the identification information displayed on the upper cover and displayed on the lower cover A part of the identification information does not match, and it is possible to quickly detect a situation in which the upper cover is illegally removed. Therefore, it is possible to prevent, with high precision, a situation in which the illegal player operates conveniently with high precision.
