DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a board case of a game machine.

[0002]

2. Description of the Related Art A board mounted on a main body of a game machine has an R board.
An OM is mounted, and the ROM stores programs such as a game proceeding method and data such as definitions and probabilities.

If these data are falsified, various disadvantages arise for the hall in which the gaming machine is installed.

[0004] Therefore, conventionally, various measures have been taken so that the ROM is wrapped with a cover so that the ROM cannot be easily touched, and the cover cannot be easily opened.

[0005]

However, no matter how tightly the cover is closed, it is difficult to completely prevent the cover from being pryed open by using a tool, and the cost is increased by firmly closing the cover. But it becomes a problem.

According to the present invention, the cover enclosing the ROM cannot be easily pryed open, the prying of the cover can be prevented at a low cost, and when the cover is pryed open, the trace is clearly visible. It is an object of the present invention to provide a lock device for a board case of a gaming machine which can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a lock device 100 for a board case of a game machine according to an embodiment of the present invention.
FIG.

Locking device 100 for a substrate case of a game machine
Is a locking device for a board case of a gaming machine that forms a case of a predetermined substrate 30 with the lower lid 10 and the upper lid 20 and locks the case. The lower lid 10 and the upper lid 20 cover the substrate 30. Sometimes, the lower lid 10 and the upper lid 20 are connected by the embedded nut 40.

Further, a small-diameter portion 13 is attached to an end 11 of the lower lid 10.
The protrusion 12 is provided through the through hole, and the protrusion 12 has a through hole 12.
H is provided. At the end 21 of the upper lid 20, the small diameter portion 2
3, a protrusion 22 is provided.
2H is provided. The embedded nut 40 is fitted in the through holes 12H and 22H.

In the above embodiment, the projection 22 has the through hole 22H. Instead of the through hole 22H, a hole (a hole having a bottom) may be provided.

FIG. 2 shows a lock device 100 for a substrate case.
FIG. 2 is a sectional view taken along line II-II ′ of FIG.

The embedded nut 40 has a flange 41 and a wedge 42 as shown in FIG. Also, the embedded nut 40 is a kite nut, but instead of the kite nut,
Another embedded nut, such as an insert nut, may be used.

Although the embedding nut 402 and the flange 41 are provided in the above embodiment, the flange 41 may be omitted.

Next, the operation of the above embodiment will be described.

FIG. 3 shows a locking device 100 for a substrate case.
FIG. 3 is an exploded view of the vicinity of the protrusions 12 and 22.

First, the through hole 12H of the projection 12 of the lower lid 10
And the through hole 22H of the protruding portion 22 of the upper lid 20 are opposed to each other, and in FIG.
2H and further into the through hole 22H.
As a result, the lower cover 10 and the upper cover 20
It is fixed and locked near 1 and 21. In addition, the lower lid 10 and the upper lid 20 are fixed by screws 20b.

Conventionally, a ROM mounted on a substrate 30
In order to prevent falsification of the slot machine, studies have been made to prevent the board 30 from coming off the body of the slot machine. However, it is difficult to keep the board 30 from coming off the body. Rather than preventing the substrate 30 from detaching from the main body, the substrate 30 leaves a trace of being detached from the main body, and if there is such a trace that the substrate 30 is detached from the main body of the slot machine, the substrate 30 of the slot machine is The damage can be minimized by, for example, exchanging a normal one.

In the above embodiment, the embedded nut 4
0, so the cover that wraps the ROM (lower lid 1
0, since the upper lid 20) cannot be easily pry open, and the inexpensive embedded nut 40 that is easy to procure is used, the prying of the cover can be prevented at low cost.

FIG. 4 is a perspective view showing a board case locking device 200 according to a second embodiment of the present invention.

The lock device 200 for the board case is provided with three sets each including the protrusion 12 and the protrusion 22, and is provided with only one embedded nut 40.

In this way, if the wrong person removes the embedded nut 40 or deforms the set composed of the projection 12 and the projection 22, etc. 13 and 23, the embedded nut 40 is fitted into a set composed of the normal projection 12 and the projection 22 which is provided next to the set that has been removed, and is constituted by the lower lid 10 and the upper lid 20. The case 30 is locked to protect the substrate 30. That is, the board case locking device 200 can be easily reused, and resources can be saved.

In the above embodiment, the lower lid 10 and the upper lid 20
May be reversed. That is, the protrusion 22 may be provided on the lower cover 10, the protrusion 12 may be provided on the upper cover 20, and the embedded nut 40 may be pushed from above the upper cover 20 in FIG. 1.

Further, although the above embodiment is directed to a lock device for a board case of a slot machine, the above embodiment may be applied to a lock device for a board case of a gaming machine other than a slot machine. That is, in the above embodiment,
The first lid and the second lid constitute a case of a predetermined substrate, and in the locking device for a substrate case of a gaming machine for locking the case, the first lid and the second lid define the case. This is an example of a locking device for a board case of a gaming machine in which the first lid and the second lid are connected by an embedded nut when the board is wrapped.

In the above embodiment, the first projection provided at the end of the first lid, the through-hole provided in the first projection, and the second lid are provided. A second projection provided at the end of the first projection, and a hole provided at the first projection, wherein the embedded nut is fitted into the through hole and the hole. It is an example of a locking device for a substrate case of a machine.

The lock device 200 for the board case is provided with three sets each including the protruding portions 12 and the protruding portions 22. However, two or four or more sets may be provided. Good.

When the board case is fixed to the gaming machine housing, the lock device of the above embodiment may be applied. That is, the gaming machine housing and the board case may be connected by the embedded nut.

[0028]

According to the present invention, the cover for enclosing the ROM mounted on the board cannot be easily pry open.
Opening of the cover can be prevented at a low cost, and if the cover is opened, the trace of the cover can be clearly seen.
