The attachment to the attachment auxiliary member 81 may be performed before the upper cover member 27 is attached to the attachment base member 26 or before the outer cover member 28 is attached to the upper cover member 27 attached to the attachment base member 26. .

Then, the insertion end of the mounting member 86 provided on the mounting auxiliary member 81 is connected to the mounting base 8 of the back mechanism panel 10 of the gaming machine.
The mounting auxiliary member 81 is attached to the back mechanism board 10 together with the circuit board box 24 by being locked in the mounting hole of No. 0.

On the other hand, the IC 31 of the circuit board 25 of the public agency
At the time of inspection, etc., the circuit board box 24 together with the mounting auxiliary member 81 is removed from the mounting base 80 of the back mechanism panel 10 of the gaming machine, and the fixing means 58 of the top wall portion 53 of the outer lid member 28 is fixed. The connecting portions 63 at both ends of the slit 64 of the portion 60 are cut. As a result, the connection between the outer lid member 28 and the upper lid member 27 is released, and the outer lid member 28 can be removed. In this case, the distal end of the leg 70 of the fixing member 61 is connected to the top plate 40 of the upper lid member 27.
, The fixing member 61 and the portion of the embedded portion 65 at the center of the inside of the slit 64 remain as a trace.

Then, the upper lid member 2 is attached to the mounting base member 26.
When the screw 43 to which the cover 7 is attached is removed, the upper lid member 27 is opened.

The mounting table 80 of the back mechanism panel 10 of the gaming machine
While the circuit board box 24 is attached via the attachment auxiliary member 81, the fixing means 58 in the fixed state of the top wall portion 53 of the outer lid member 28 is broken (the connecting portions 63 at both ends of the slit 64 are cut). Can also. In this assembled state, if the board fixing screws 75 are removed from the outer lid member 28, the guide portion 55 of the upper lid member 27, and the through holes 54 and 46 of the locking portion 45, only the circuit board box 24 can be removed.

A plurality of fixing means 58 for preventing unauthorized opening of the circuit board box 24 are constructed by the top plate portion 40 of the upper cover member 27 located above the board surface of the circuit board 25 and the outer cover member 28. , That is, the surface of the circuit board box 24 (the side opposite to the mounting portion of the mounting auxiliary member 81).
Since the fixing means 58 is provided in the area, the fixing means 58 does not take up extra space, and the area where the circuit board box 24 can be arranged on the back surface of the gaming machine can be enlarged. Therefore, the circuit board box 24 can be made relatively large, and the circuit board 25 itself can be made large, so that the degree of freedom in designing the circuit board 25 is increased.

Further, the upper cover member 27 is fixed to the mounting base member 26 on which the circuit board 25 is mounted by fastening means (screw 43), and the fastening means is covered by the outer cover member 28. The box 24 is not illegally opened. In this case, even if the semicircular cover portion 57 formed on the peripheral wall end of the outer lid member 28 is cut off, the covering state of the fixing means is maintained by the peripheral wall end of the outer lid member 28. Is not removed, and illegal opening of the circuit board box 24 can be reliably prevented. Further, the upper cover member 27 does not open just because the fixing means 58 is damaged or broken. Further, the fixing means 58
Even if is destroyed, if you do not remove the fastening means further,
Since the circuit board 25 itself cannot be removed, unauthorized operation on the circuit board 25 can be reliably prevented.

When the fixing means 58 in the fixed state is broken (the connecting portions 63 at both ends of the slit 64 are cut), the fixing member 61 and the embedded portion 6 in the center of the inside of the slit 64 are cut.
5 is cut off from the top wall portion 53 of the outer lid member 28, and these portions are separated by a partition wall 73 standing upright on the top plate portion 40 of the upper lid member 27 so as to surround both sides of the embedding portion 65. It is kept as it is and remains as a trace. For this reason,
It is easy for a store clerk at an amusement store to know whether or not the circuit board box 24 has been opened. In general, a pachinko gaming machine maker fixes a predetermined fixing means 58 at the time of shipment from a factory, but usually does not break the fixing means 58 after installing it in a game shop. Therefore, after installation in a game store, despite the absence of inspection, the fixing means 58
If traces of destruction remain, it is easy to recognize that an illegal act has been performed. Further, the number of times of opening the circuit board box 24 can be easily recognized from the trace.

On the other hand, the I of the circuit board 25 is
When inspecting the C (or ROM) 31 or the like, if the connecting portions 63 at both ends of the slit 64 of the mounting portion 60 to which the fixing means 58 of the circuit board box 24 are fixed are cut, the fixing means 58 is broken. You. That is, the top wall portion 53 of the outer lid member 28

Further, after the cutting, the outer lid member 28 is removed, and if the fastening means for attaching the upper lid member 27 to the mounting base member 26 is removed, the upper lid member 27 is opened. In this case, the top plate portion of the upper lid member 27 is opened. 40 central step 48
Is provided with an opening 50 for attaching and detaching the IC 31 of the circuit board 25, so that the IC 3
1 can be removed. Therefore, the inspection of the stored data and the like of the IC 31 can be easily performed.

Further, a seal related to the inspection of the IC 31 and the like of the circuit board 25 by a public organization near the fixing means 58,
An identification code such as a number indicating the order of opening is given. That is, since the order and combination of the plurality of fixing means 58 related to the fixing of the fixing member 61 can be identified, the fixing of the predetermined fixing member 61 can be surely performed without making a mistake in the fixing order and combination at the time of an inspection or the like. Can be done. Further, if the colors of the fixing members 61 having different orders (identification codes) are changed, the order and combination of the fixing can be more easily identified, and the workability at the time of inspection is further improved.

Further, since the outer cover member 28 is provided on the upper cover member 27 to seal the circuit board box 24, even if these are formed of a transparent resin, the entire interior is difficult to see.
The opening 50 of the top plate 40 of the upper lid member 27 is
For this reason, it is easier to see the inside from the portion of the opening 50 than in the other portions, and therefore, even if the electric parts of the circuit board 25 are illegally replaced, the opening 50
It is easy to find out that the electric component has been replaced from the part.

Further, at the time of inspection or the like, a portion where the connecting portions 63 at both ends of the slit 64 are cut off and the fixing means 58 is cut off becomes an opening hole, but below the opening is a separated concave chamber 52. Further, since the opening 50 of the top plate portion 40 is located at the central step portion 48 at a high position, it is possible to prevent wire or the like from being inserted into the opening 50 through the opening hole, for example. Further, since the adjacent fixing means 58 are separated from each other by the partition wall 73 erected on the top plate portion 40 of the upper lid member 27, similarly, the adjacent fixing means 58 are separated from the opening hole of the part where the fixing means 58 is separated. It is possible to prevent a wire or the like from being inserted into the latching hole 62 to perform wrongdoing.

Since the game control device 20 controls the game in a comprehensive manner, the IC (or RO) of the circuit board 25 is controlled.
M) It is easy to perform fraudulent actions such as frequent occurrence of jackpots by exchanging 31 or rewriting data stored in the IC 31. However, since the circuit board 25 is housed in such a circuit board box 24, Can be reliably prevented, and even in the event of a fraudulent act, it can be quickly detected and high reliability can be ensured.

Also, the fixing holes 58 of the top plate portion 40 of the upper lid member 27 of the fixing means 58 and the top wall portion 53 of the outer lid member 28 are formed.
Slit 64 also functions as a heat radiation hole.

Further, the outer cover member 28, the guide portion 55 of the upper cover member 27, the locking portion 45 while the mounting auxiliary member 81 and the circuit board box 24 are attached to the back mechanism panel 10 of the gaming machine.
If the board fixing screw 75 is removed from the through holes 54 and 46 of
Since only the circuit board box 24 can be removed, when the inside of the circuit board box 24 is visually recognized from the back surface, the operation can be easily performed and the inspection property is good.

Conventionally, the above-mentioned overlapping portion has been fixed using a metal member such as a one-way screw.
Therefore, parts made of a different material from the circuit board box made of resin are required, and the cost is increased accordingly. On the other hand, in the present embodiment, since the fixing member 57 can be formed of resin, the cost can be reduced. Also,
In particular, when the fixing member 57, which is a separate member from the circuit board box, is made of resin, it is easy to change the resin color. Therefore, by changing the color of the fixing member 61 itself,
It is possible to easily display the order and the combination of the fixing.

In the embodiment, the game control device 20
Although an example in which the present invention is applied to the circuit board box described above is shown, the present invention can be applied without limitation to an IC having the same important components as an IC storing a game program. Also,
The circuit board box is not only one game control device,
It may house an emission control device or another control device.

Although an example in which the present invention is applied to a pachinko gaming machine as a gaming machine has been described, other gaming machines, such as pachislot machines,
It can also be applied to gaming machines such as arrangement balls.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
