To do so, it is necessary to reproduce the color of the cut portion. However, it is difficult to reproduce the color of such a cut portion, and it is not easy to hide traces of the cut. Therefore, it is not possible to reliably conceal the wrongdoing, so that the wrongdoing can be detected at an early stage and the wrongdoing can be suppressed.

It is sufficient that the color of the box sealing member 210 is different if the colors of the sealing members 21 and 31 opposing each other are different. For example, all the sealing members 21 of the sealing unit 20 are changed to one color (for example, one color). , Red), and all the sealing members 31 of the sealing unit 30 facing the sealing unit 20 may be colored in another color (for example, green). Further, each of the four sealing members 21 of the sealing unit 20 is colored in a different color, for example, red, blue, yellow, or green, and the sealing member 31 facing the red sealing member 21 is replaced with a green or blue sealing member 21. Sealing member 3 facing
1 is a sealing member 31 opposed to the yellow sealing member 21
The sealing member 31 facing the blue and green sealing members 21 may be colored red.

Further, the box sealing tool 210 of the third embodiment
Are the outer peripheral surfaces (outer perimeters) of the sealing members 21 and 31
When the substrate box 1 is opened by cutting the box sealing member 210 using a tool such as a saw, since wire members 212 and 312 made of wire material and the like are provided around the grid at substantially equal intervals. Then, the teeth of a tool such as a saw are hooked on the wire member 212 or the wire member 312. Therefore, when cutting is performed with a tool such as a saw, the portions of the sealing members 21 and 31 other than the cut portions are broken by the wire members 212 and 312, and traces of the cutting can be left. It is not easy to repair the sealing members 21 and 31 that have been destroyed in this way to conceal traces of cutting, and it is impossible to reliably conceal fraudulent acts. Therefore, the misconduct can be detected early and the misconduct can be suppressed.

According to the gaming machine substrate box sealing tool 3, when the gaming machine substrate box is opened by cutting the connecting sealing member connecting the sealing members using a tool such as a saw, the first sealing member and the second sealing member are used. 2 The vicinity of the surface facing the sealing member must be cut. Since each sealing member is colored in a different color from each other, the cut portion of the gaming machine substrate box sealing device 3 is repaired using an adhesive or the like, and the color of the cut portion is reproduced in order to conceal the cut. There is a need to. However, it is difficult to reproduce the color of such a cut portion, and it is not easy to hide traces of the cut. Therefore, it is not possible to reliably conceal the wrongdoing, so that the wrongdoing can be detected at an early stage and the wrongdoing can be suppressed.

[0082] In one of the gaming machine substrate box sealing devices 1 to 3, or in the gaming machine substrate box sealing device according to claim 1, a wire material is provided on the outer periphery of the first sealing member and the second sealing member. A board box sealing device 4 for a gaming machine, which is provided in a grid pattern. According to the gaming machine substrate box sealing device 4, since the wire members are provided in a grid around the outer periphery of each sealing member, the gaming machine substrate box sealing device 4 is cut using a tool such as a saw. When opening the game machine substrate box, the teeth of a tool such as a saw are caught on the wire material. Therefore, when cutting is performed by a tool such as a saw, each part of the sealing member other than the cut part is broken by the wire material, and a trace of cutting can be left. It is not easy to repair the sealing members broken in this way to conceal the traces of cutting, and it is impossible to conceal fraudulent acts reliably. Therefore, it is possible to detect fraudulent acts at an early stage and to suppress such fraudulent acts.

[0083]

According to the gaming machine substrate box sealing device of the present invention, the opposing surfaces of the first sealing member and the second sealing member connected by the connecting sealing member are each formed into a concave and convex shape adapted to each other. . Therefore, even if a thin plate-shaped tool or the like is inserted between the opposing surfaces and the gaming machine substrate box sealing tool is forcibly opened and opened, the thin plate-shaped tool or the like is applied to the concavo-convex surface of each sealing member. Since it is caught, the insertion can be prevented. Therefore,
There is an effect that it is possible to prevent prying of the game machine substrate box and prevent improper act on the circuit board stored in the game machine substrate box.
