DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine base box (hereinafter, referred to as a base box) for storing a control base of a game machine.

[0002]

2. Description of the Related Art In current pachinko machines and slot machines, the game content is controlled by a control base including a microcomputer. This control board is housed in a square box-shaped base box, and is usually attached to the back of a game board or a mechanism board. The base box has a box base covered with a box cover.

[0003]

In recent years, there has been a problem of fraudulent acts of changing game contents, such as removing a built-in ROM from a control board in a base box and replacing it.

[0004] The present invention has been made in view of the above, and an object of the present invention is to make it difficult to illegally open a box cover.
An object of the present invention is to provide a base box for facilitating detection of unauthorized release.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a box base attached to a gaming machine, a box cover covering the box base, and a box base and box cover connected by fastening means. When in the set state where the fastening means cannot be removed, the destruction of its own components is an essential requirement for the box cover release,
And a release indicator having a single-use structure whose breaking portion indicates the release of the box cover, and a plurality of the release indicators are provided, a part of which is set, and the box cover is set when the box cover is released. I tried to destroy a component of a release indicator and use it up.
Provided is a gaming machine base box in which a remaining unused release display means is set when the box cover is closed.

Since the destruction of the components of the release indicating means is an essential requirement for releasing the box cover, it is difficult to illegally open the box cover. Also, the release display means,
Once the box cover is opened, traces remain when the box cover is opened because it is a single-use structure that cannot be repaired once it is destroyed. Therefore, it is easy to find an illegally opened box cover. On the other hand, since a plurality of release display means are provided and used in an arbitrary order, the box cover can be opened a plurality of times for inspection or the like, and the number of times the box cover is opened also shows a trace of the release display means. It is easy to understand by counting.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of the base box, FIG. 2 is a cross-sectional view taken along line XX of FIG. 1, and FIG.
3 (b) is a partially enlarged sectional view showing a state in which the release indicating means is broken, and FIG. 4 is a rear view of the pachinko machine.

As shown in FIG. 4, the base box 1 is attached to a winning ball collecting cover 3 provided on the back side of the game board 2 in a pachinko machine P which is a kind of a game machine, for example. The base box 1 includes a box base 1a made of synthetic resin and having a transparent rib 4 protruding from the outer periphery of a square plate 4, a box box 1b made of synthetic resin and having a transparent box shape, and release display means to be described later. 6, and a control board (not shown), which is an assembly of electronic components such as a built-in ROM, is housed inside.

There are four release indicating means 6 at the corners of the base box 1, and as shown in FIGS. 2 and 3A, a female screw shaft 6a protruding from the box base 1a and a box cover 1b. The screwing portion 6b provided and the detachable screw 6c as a fastening means are constituent elements. The female screw shaft 6a has a female screw hole 6d at the center of the tip.

On the other hand, the screwing portion 6b of the release indicating means 6 has a bottomed cylindrical shape having a screw hole 6e at the center.
As shown in (a), the pachinko ball B has an inner diameter that fits tightly and a depth that fits comfortably, and a gently tapered portion 6f for the purpose of facilitating the insertion of the pachinko ball B into the inlet portion.
Is provided. The lower half of the screwing portion 6b is sunk into the base box 1 so that the height of the portion protruding above the box base 1a is suppressed. Further, a V-groove 6g for facilitating breaking (breaking) is formed in the outer periphery of the base end portion protruding above the box base 1a in the screwing portion 6b.

When the pachinko ball B is forcibly pushed into the screwing portion 6b, the entirety sinks in a tightly fitted state. The pachinko ball B once fitted into the screwing portion 6b is in a so-called fitted-in state, and although a part of the spherical surface can be seen from the entrance portion of the screwing portion 6b, it fits perfectly and has no grip. I can't take it out.

Next, a method of using the base box 1 of the present invention will be described. First, the box cover 1b is put on the box base 1a, and the edge of the box cover 1b is fitted to the double rib 5 of the box base 1a. In this state, the screws 6c are respectively passed through the screw through holes 6e of the four screwing portions 6b, and are tightened into the female screw holes 6d. By doing so, the box base 1a and the box cover 1b are integrally connected.

Next, one of the four release indicating means 6 is selected, and the pachinko ball B is provided only on the screwing portion 6b.
Insert As described above, since the pachinko ball B once fitted to the screwing portion 6b cannot be taken out, the screw 6c below the pachinko ball B cannot be removed. Accordingly, when the pachinko ball B is inserted into the screwing portion 6b, the release indicating means 6 is set, and the destruction of the screwing portion 6b, which is a component of the release indicating means 6, is set as an essential requirement for releasing the box cover 1b. It was done.

Next, when opening the box cover 1b for inspecting the built-in ROM, first, as shown in FIG. 3B, the screwing portion 6b of the release display means 6 in the set state is set.
Is destroyed with tools such as nippers. At this time, screwed part 6
If the V-groove 6g of b is used, it can be easily broken and can be cut off from an accurate place. When the upper half of the screwed portion 6b is cut off from the V-groove 6g, the upper half of the pachinko ball B is exposed to the outside, so the pachinko ball B is taken out and the screw 6c is removed. Then, the box cover 1b can be opened by removing all the screws 6c of the release indicator 6 in the other unset state.

Next, a case where the box cover 1b is closed again after the inspection is completed will be described. As described above, the release indicating means 6 in which the screw portion 6b is broken when the box cover 1b is opened is broken and has been used up since the screw portion 6b cannot be repaired. Therefore,
One of the remaining three unused release indicating means 6 is selected, the screw 6c is tightened in the same manner as described above,
Put the pachinko ball B into b and set it into the set state. And
The box cover 1b and the box base 1a are integrally connected by screwing the remaining three screwing portions 6b including the previously used release indicating means 6 through the screws 6c into the female screw holes 6d. In this state, since the screwing portion 6b of the previously used release indicating means 6 is cut off from the V-groove 6g and is lost, the box base 1a is opened once by a clear trace (destruction portion). At a glance.

Since there are four release display means 6 in the embodiment, if one set is used each time the set state is set, the box cover 1b can be opened up to three times. If the fourth cover 6 is used up and the box cover 1b is completely opened, the entire box cover 1b must be replaced.

Although the present invention has been described with reference to the embodiment, it is needless to say that the present invention is not limited to the above embodiment. For example, in the embodiment, the pachinko ball B is used as a means for preventing the screw 6c from being detached in the release display means 6, but as shown in FIG. 5, the release display means 6 is set using the special screw 6h which can only be tightened. It may be. Then, the pachinko ball B of the embodiment is unnecessary. The special screw 6h has, for example, a special cross-shaped groove formed on the head portion that engages with the driver only in the tightening direction, so that the driver idles in the loosening direction. Since such a special screw 6h cannot be removed once it is tightened, a joint 6i that is easily broken (ruptured) is formed around the screwed portion 6b, and the joint 6i is formed.
And a single-use structure in which the entire screwed portion 6b is separated from the box cover 1b.

In the embodiment, the number of the release display means 6 is set to four, but the number can be changed as appropriate. Furthermore, the release display means 6 is set to 2
It is also possible to set one (plural) to use up.

[0019]

According to the base box of the present invention, it is difficult to illegally open the box cover because the destruction of the components of the release display means is an essential requirement for opening the box cover. Further, since the release indicating means has a single-use structure in which the part cannot be repaired once it is destroyed, a trace remains when the box cover is opened. Therefore, it is easy to find an illegally opened box cover. From the above, fraud such as replacing the internal ROM can be effectively prevented. On the other hand, since a plurality of release indicating means are provided and used in an arbitrary order, it is possible to open the box cover a plurality of times for inspection or the like.
