2A, it may be provided over the entire circumference of the case body 161.

Here, the insulating oil 180 filled in the substrate case 160 is a synthetic oil (for example, silicone oil, rapeseed ester oil, poly-α-olefin oil, etc.),
Mineral oil or the like having a predetermined transparency. In addition,
The predetermined transparency depends on the shape of the CPU 152 and other ICs mounted on the control board 151 from the outside of the case body 161.
It suffices that the mounting state or identification information (for example, model number, chip ID) and the like can be visually recognized.

The insulating oil 180 is required to have an insulating property as long as the circuit and terminals of the control board 151 do not cause a short circuit and can operate in the same manner as in the atmosphere. Although the insulating oil 180 is used as the insulating liquid here, the insulating liquid is not limited to oil and may be any liquid having insulating properties and predetermined transparency.

Is attached, and the control board 151 is fitted into the notch 169 and then sandwiched by the lids 162A and 162B, so that the insulating oil 180 is prevented from leaking from the joint portion between the control board 151 and the lid 162 protruding to the outside. .

That is, when the substrate case 160 is composed of a box body and a lid body, a seal member (leak prevention member) is provided at the contact portion between the box body and the lid body, and the insulating oil 1 inside
The leakage of 80 is prevented. In the case where a plurality of lids are provided, the signal line or the control board may be sandwiched by the plurality of lids. In this case, the lid body is provided with a seal member at a contact portion with the signal line or the control board.
The box body is configured such that the electronic component mounting surface when the control board is stored is transparent (or has a predetermined transparency).

Incidentally, in FIGS. 6 and 7, the lid 162A,
At both ends (left and right ends in the drawing) of 162B, flange portions 165 and 166 are provided in a protruding manner at positions facing each other. In addition, a hole 165A is formed through the flanges 165, 166 at the same coaxial position, and a pair of lids 162A, 1A are connected by fastening a bolt 141 inserted in the hole 165A.

68 and 168 are respectively provided so as to project, and the lid 162A also faces the flange portion 168 of the case body 161 (the lid 1
Flange portions 167 and 167 are provided on both ends of 62A so as to project. Further, a hole 168A is formed in the flanges 167, 168 at the coaxial position, and a lid 162 holding the control board 151 is connected to the case body 161 by a bolt 142 inserted in the hole 168A. The seal member 203 is provided between the lid 162 and the case body 161.
To prevent the insulating oil 180 from leaking from the joint between the case body 161 and the lid 162.
0 Insulating oil 180 filled inside is sealed.

The operation of the above configuration will be described below.

First, as shown in FIG. 5, the control board 15
Since the front and back of No. 1 are immersed in insulating oil 180, C
Heat generated by elements on the substrate such as the PU 152 is transferred to the insulating oil 180. And insulating oil 180
The heat transferred to the air is released into the atmosphere via the case body 161. Therefore, like the back of the gaming machine, the control board 1
Even when the arrangement of 51 is not necessarily a suitable place for cooling, the CPU 152 can be reliably cooled without providing a heat radiating member on the surface of an element such as a heat sink by radiating heat through the entire substrate case 160. As a result, various effects can be realized by using the high-performance CPU 152.

Also, of the control boards 151, the one with a large amount of heat generation (for example, the CPU 152) is the control board 151.
Since it is provided in the lower part of the case, as shown by the arrow in FIG. 5, the insulating oil 180 can generate convection from the bottom to the top of the case body 161, and then to the bottom, which enables uniform heat dissipation. Therefore, the cooling performance can be improved.

Further, since the front and back of the control board 151 are each cooled by the insulating oil 180, the cooling performance can be improved as compared with the case where only a single surface is cooled, and the control board 151 is cooled. Since 151 is supported by the pedestal 172 and a gap is provided between the pedestal 172 and the bottom of the case body 161, when the temperature difference between the front surface and the back surface of the control board 151 is large, the insulating oil 180 is applied to the front surface and the back surface of the control board 151. It is possible to improve the cooling performance by generating convection between them.

Further, since the substrate case 160 and the insulating oil 180 are provided with translucency (predetermined transparency), the substrate 151 and the elements on the substrate 151 can be visually recognized from the back surface of the game machine. Even if the substrate is replaced with an unauthorized one, it is possible to easily find it, it is possible to suppress an unauthorized action, and it is possible to prevent the unauthorized action and ensure the cooling performance at the same time.

The cap 191 may be removable, and a scale 192 may be provided on the injecting portion 190 of the insulating oil 180 so that the reference value can be easily confirmed. In this case, the liquid level is lowered. In such a case, the insulating oil 180 can be quickly replenished to maintain the cooling performance. However, in this way insulating oil 1
When replenishing 80, it is desirable to use a special sealing method (use of a special tool, etc.) in order to achieve both improper countermeasures.

Further, it may be replaced with an illegal board,
When an illegal component is attached, the liquid surface changes when the volumes of the legal substrate and the illegal substrate are different. Therefore, if a doubt arises in the control substrate 151, the liquid surface may be compared with the reference value. It can help detect fraud.

When the board is replaced with an illegal board,
Since the legitimate board is removed with the insulating oil 180 attached, the insulating oil 180 can be removed from the back surface or floor of the game machine.
There is a very high possibility that the dripping will occur, and unauthorized replacement of the substrate can be easily determined based on the state of the oil leaking to the surroundings in addition to the drop in the liquid level.

By adding a predetermined odor to the insulating oil 180, it is possible for a clerk of the game store to easily know that the lid 162 of the case 160 has been illegally opened, and further fraudulent acts. Will be a deterrent against. However,
In a normal state, the lid 162 seals the case body 161, so that odor does not leak to the outside.

The control board 151 needs to be visually recognized if the component mounting surface of the control board 151 (the side on which the CPU 152, which is a heating element is provided) is easily visible when the gaming machine 1 is opened and the back surface is viewed. Therefore, only the front surface 160F facing the component mounting surface may be formed of a transparent member such as transparent acrylic, that is, a visible member having a predetermined transparency.

On the other hand, visibility is not required for other surfaces. Therefore, these surfaces are formed of a member having a good heat dissipation property (a metal having a high heat conductivity, etc.) without considering the visibility to serve as a heat dissipation part, so that the heat generated from the control board 151 is transferred to the insulating oil 180. Transmitted, and insulating oil 18
The heat transferred to 0 is formed as a heat dissipation part,
And is transmitted to the bottom surface 220 and cooled by the atmosphere to effectively dissipate heat generated from the control board 151.
The board case 1 is ensured by cooling the heating elements such as 2.
Visibility can be secured while improving the cooling performance of 60.
Further, by providing the cooling fins 211 on the surface made of these metals, the cooling performance can be further enhanced,
