When an external force is applied from the direction E in the drawing as shown in the DD section of (b), the side walls of the cover member 120 and the base member 110 are elastically deformed as shown by the two-dot chain line in the drawing, and the cover member In some cases, the engagement state between the base member 110 and the base member 110 may be released. For example, in this case, if a person inserts a tool into a gap generated at a joint portion between the base member 110 and the cover member 120 and pryes it open, the ROM may be replaced without following a regular procedure. Thereafter, if the inserted tool is removed and restored, it is extremely difficult to find a trace of ROM replacement.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a substrate case sealing structure for effectively preventing an illegal act from being performed on a circuit board mounted thereon. With the goal.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, a board case according to claim 1 is provided between a base member fixed to a game machine and a base member which is superposed on the base member. A cover member that forms a predetermined storage space, a base side wall portion is provided on a peripheral edge of the base member and extends in a direction in which the cover member overlaps, and a peripheral edge of the cover member is provided on the peripheral edge. A cover side wall extending in the direction of overlap with the base member and at least partially overlapping the base side wall, and a first engagement projecting from the base side wall and partially projecting toward the cover side wall. The cover member is supported by the base member, and the cover member is overlapped with the base member by engaging the portion with the second engagement portion that is partially protruded from the cover side wall portion toward the base side wall portion side. In the state, By fixing the base member, a circuit board having electronic components mounted to control the gaming machine, a board case of the gaming machine for sealing in the housing space,
At least one of the cover member and the base member has a first
In the direction in which the engagement between the engagement portion and the second engagement portion is released, the first
It is characterized in that an engaging portion fluctuation preventing means for preventing the engaging portion or the second engaging portion from being deformed and / or fluctuated is provided.

Thus, the engagement between the first engagement portion and the second engagement portion is released by the engagement portion variation preventing means being attached to at least one of the cover member and the base member. The deformation and / or fluctuation in the direction can be effectively prevented, and the circuit board is not illegally replaced.

[0008] Various configurations are conceivable as specific configurations of the board case. For example, as described in claim 2, the first engagement portion is slid along the cover side wall portion.
A configuration in which the cover member is supported by the base member by engaging the second engagement portion is conceivable.

Further, the above-mentioned engaging portion fluctuation preventing means engages the side wall portion of the base or the side wall portion of the cover on the side opposite to the second engaging portion or the first engaging portion. It is conceivable to configure to stop. According to such a substrate case, for example, when the engaging portion variation preventing means is provided on the cover member side, the cover member and the base member are formed by the second engaging portion of the cover member and the engaging portion variation preventing means. Will be fixed. For this reason, even when a force is applied to push the cover member from the outside as in the above-described conventional example, the base side wall portion abuts on the engagement portion variation prevention means to prevent the cover member from being elastically deformed. Therefore, it is possible to effectively prevent a third party from fraudulently opening the board case.

When the engaging portion variation preventing means is provided on the base member side, the cover side wall is sandwiched between the first engaging portion of the base member and the engaging portion variation preventing means. Thus, the cover member and the base member are fixed. For this reason, even in this case, even if a force that pushes the cover member from the outside is applied, the engaging portion fluctuation preventing means contacts the cover side wall portion to prevent the cover member from being elastically deformed. It is possible to effectively prevent illegal acts such as prying open the board case by three parties.

As described above, it is possible to effectively prevent a third party from misbehaving only by providing the engaging portion fluctuation preventing means on one of the cover member and the base member. It is preferable to provide the engaging portion fluctuation preventing means on both sides, since the cover member is more firmly fixed.

[0012] Further, such an engagement portion fluctuation preventing means includes:
As described above, for the base side wall portion or the cover side wall portion,
If provided on the opposite side to the second engagement portion or the first engagement portion,
The above-described effect can be obtained even if the engagement portion is shifted from the second engagement portion or the first engagement portion. More preferably, it is provided at a position facing the portion or the first engagement portion.

When a third party opens the board case,
It is considered that a pressing force is applied to the vicinity of the first engagement portion and the second engagement portion in order to release the engagement state of the engagement portion between the cover member and the base member. This is because it is preferable to dispose the engaging portion fluctuation preventing means at the positions of the engaging portion and the second engaging portion.

When the engaging portion fluctuation preventing means is provided on one of the cover member and the base member, the engaging portion fluctuation preventing means is provided on the base side wall portion or the cover side wall. Preferably, the cover member extends parallel to the base portion and guides the base side wall portion or the cover side wall portion when the cover member slides.

[0015] By using the guide function as the engagement portion variation preventing means in this way, the cover member can be smoothly slid with respect to the base member to bring it into a predetermined engagement state. On the other hand, from the same viewpoint, when the engagement portion variation prevention means is provided on both the cover member and the base member, as described in claim 6, at least one of the engagement portion variation prevention means includes: It may be configured so as to extend in parallel with the base side wall or the cover side wall and guide the base side wall or the cover side wall when the cover member slides.

In this case, if both of the engaging portion fluctuation preventing means extend in parallel with the base side wall portion and the cover side wall portion, the cover member can be guided more stably. According to a seventh aspect of the present invention, the cover member is provided with a covering portion that is provided continuously outside the cover side wall portion and covers the first engaging portion and the second engaging portion from outside. Thus, there is no problem that dust and the like are clogged in both engagement portions and hinder assembly of the cover member and the base member. Therefore, even if the opening interval of the substrate case for inspecting the substrate is long, the substrate case can be smoothly opened or sealed. Further, by providing the covering portion in this way, the deformation / fluctuation portion due to the lateral pressure is covered, so that the deformation / fluctuation can be more efficiently prevented.

In this case, the covering portion extends in the direction of overlap with the base member and extends in parallel with the base side wall portion. It is more preferable that a guided portion serving as a means is provided, and the guided portion is guided by the base side wall portion when the cover member slides.

According to this configuration, the same effects as those of the above-described claim 5 or claim 6 can be obtained, and the configuration of the cover member is reasonable.

0 fixes the base member 10 and the cover member 20 to each other so as to sandwich the base member 10 and the cover member 20 to seal the substrate case 1. At this time, since the fixing member 50 is loosely fitted into the communication hole, the fixing member 50 is rotatable around its own axis.

In this sealing operation, a pair (two) of symmetrically disposed ones of the four pairs (eight in total) of fixing members 50 disposed on the left and right are used. In the case of the example, sealing can be performed a total of four times including the time of shipment of the pachinko machine. When releasing the sealing state, the support ribs 24 of the cylindrical member 25 and the support ribs 14 and 16 of the cylindrical member 15 that hold the fixing member 50 used at this time are cut with a tool such as a nipper. By removing the cover member 20 and performing the above operation in reverse, the cover member 20 can be detached from the base member 10.

The substrate case 1 sealed in this manner is a metal plate 7 for shielding electromagnetic waves (for preventing fraud).
It is attached to the back side of the pachinko machine through the “0”. As described above, in the board case 1 of the present embodiment, the protection ribs 19 are provided at positions opposing the engagement portions 18 of the base member 10, and the cover side walls are formed by these engagement portions 18 and the protection ribs. The cover member 20 and the base member 10 are fixed so as to sandwich the cover 27. The cover member 20 is formed by a guide rib 29 continuously provided outside the cover member 20 and an engagement portion 31 extending from the cover side wall portion 27.
The cover member 20 and the base member 10 are fixed in such a manner that the engaging portion 18 is sandwiched.

Therefore, even if a force is applied to push the cover member 20 from the outside, the protective ribs 19 and the guide ribs 29 prevent the cover member 20 from being elastically deformed and fluctuated. Unauthorized acts such as prying open the case 1 can be effectively prevented.

In this embodiment, the protection rib 19 and the guide rib 29 correspond to the engagement portion fluctuation preventing means. The embodiments of the present invention have been described above. However, the embodiments of the present invention are not limited to the above-described embodiments, and may take various forms as long as they fall within the technical scope of the present invention.
