Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control board box, and more particularly to a control board box suitable for containing a game control board in a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, a control board box of this type has been known as shown in FIGS. In the figure, a control board box 1 is composed of a thin box-shaped lower case 2 and an upper case 3 each having an open surface. In other words, the casings 2 and 3 are united such that the opening surfaces of the casings 2 and 3 face each other and the ends of the side walls abut each other, so that the control board 4 can be accommodated therein. Further, the lower case 2 on the side wall 3a on the upper case 3 side.
A concave portion is formed in the abutting portion with respect to the length direction, and a draw-out port 3a1 communicating with the inside and outside when formed is formed.

Here, a flat cable 5 for connecting to an external device is connected to the control board 4, and the flat cable 5 is led to the outside through the outlet 3a1. . A ROM 6 in which a game program is recorded is mounted on the control board 4 via a socket 7.

[0004]

In the above-mentioned conventional control board box, the outlet 3a1 for leading out the flat cable 5 is formed. However, there is a possibility that the ROM 6 is removed from the outlet 3a1 and replaced. There was a problem that it was sometimes performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a control board box capable of preventing unauthorized exchange of a control element such as a ROM.

[0006]

According to a first aspect of the present invention, there is provided a control board box capable of accommodating a control board and having a cable outlet. Has a structure in which the opening diameter is reduced so that the control element cannot be taken in and out while the drawer can be pulled out.

[0007] By reducing the opening diameter of the outlet, the control element cannot be moved in and out while the cable can be pulled out. Here, the shape of the control board box itself can be appropriately modified such as a thin box, a square box, or a triangle as long as it can accommodate at least the control board and has an outlet. It is.
Also, the opening diameter of the outlet does not necessarily mean the opening area of the outlet, but means the size of the gap, and even if the opening area is large as a whole, the edge of the outlet is uneven. May be formed so that a solid having no flexibility such as a ROM cannot pass through. In this case, it is possible to prevent the control element such as the ROM from being taken in and out by adjusting the interval between the irregularities.

Further, it is needless to say that the opening diameter does not always have to be circular, but can be changed as appropriate, such as square or triangular. Further, the unevenness formed at the edge of the outlet may be formed by the wall material of the control board box, or may be formed by another member. For example, in a gaming machine such as a pachinko machine, the whole is formed of metal, so that the inside can be seen through,
Transparent synthetic resins have also been used. A part of this resin may be extended to the draw-out opening to form irregularities. In addition, a completely separate member can be attached to the edge of the outlet so that the unevenness faces the inside. Needless to say, instead of forming the unevenness, a part of the synthetic resin may reduce the opening diameter of the outlet.

[0009]

As described above, the present invention provides a control board box capable of pulling out a cable, but preventing a tampering by preventing a control element such as a ROM from being taken out and replaced so that it cannot be replaced. can do.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a control board box according to an embodiment of the present invention.

In FIG. 1, the control board box 10
Is composed of a lower case member 20 and an upper case member 30. While accommodating the game control board 40 of the pachinko machine, the two flat cables 50 connected to the game control board 40 are led out. doing. The lower case member 20 and the upper case member 30 made of metal are formed in a thin box shape having substantially the same outer shape and having an open upper surface, and the two have side walls 21 and 31 with their open surfaces facing each other. Butts can be combined. Many slits for heat dissipation are formed in the lower case member 20 and the upper case member 30, and a large opening is punched out in the upper case member 30 so that the inside can be visually recognized. However, a transparent plate 60 made of a synthetic resin is attached to the upper case member 30 from the inside, so that foreign matters can be prevented from entering while making it possible to easily check the inside. further,
As for the lower case member 20, the side walls 21 a and 21 b in the short side direction and the one side wall 21 in the longitudinal direction
Guide walls 21a1 to 21c1 are formed at the end of c so as to extend inside the side wall 31 of the upper case member 30. Therefore, the abutting portion overlaps doubly, making it difficult for foreign matter to enter and pry open from the gap.

In this embodiment, the lower case member 20
The upper case member 30 and the upper case member 30 are both formed in a rectangular thin box shape with one surface opened, but any shape may be used as long as the game control board 40 can be accommodated at least. Therefore, it can be appropriately modified such as a thick box shape or a corner portion.
Each of the lower case member 20 and the upper case member 30 is formed of a rectangular bottom wall 22 or a ceiling wall 32 and side walls 21 and 31 extending at right angles from the periphery thereof. What is necessary is just to become a box shape. Therefore, it is not always necessary to extend from both cases, and it may be extended only from one case side and abut against the peripheral edge of the bottom wall 22 or the ceiling wall 32 on the other side. Absent. Needless to say, it is not always necessary for the butt portion to be double. Further, the slit for heat radiation and the opening for visual recognition inside can be appropriately modified.

The guide wall 2 of the upper case member 30
Longitudinal side wall 31 not overlapping with 1a1 to 21c1
As for d, the ceiling wall 3 is compared with the other side walls 31a to 31c.
Two concave portions 31d1 and 31d1 are formed toward the second side. The recesses 31d1 and 31d1 are connected to other side walls 31.
a to 31c, the upper case member 30
When the lower case member 20 and the lower case member 20 are combined, the outlets 33, 33 are formed to penetrate the inside and the outside, and the flat cable 50 can be led from the inside to the outside through the outlets 33, 33. .

In the present embodiment, the outlets 33 are formed at two places. However, it is sufficient that the flat cable 50 can be led out, and the number, shape and location can be changed as appropriate. That is, any communication port that is indispensable for leading out the flat cable 50 may be used. Needless to say, the cable is not limited to the flat cable 50, but may be an ordinary cord-like cable. Further, the position of the outlet 33 may be any of the side walls 31a to 31. On the other hand, the outlet 33 itself does not need to be formed on the side of the upper case member 30, and may be on the side of the lower case member 20,
It may be formed so as to straddle both.

A part of the transparent plate 60 made of synthetic resin which is mounted inside the upper case member 30 extends to the side of the outlet 33, and as shown in FIG.
A plurality of small projections 61 are formed to protrude inward from the edge portion 3. As shown in an enlarged manner in FIG.
Are set so that they cannot pass through. That is,
The dimension L1 from the tip of the small projection 61 to the facing edge is RO
The height L1 of the M80 package is shorter than the height H1 of the package, and the length L3 from the concave portion between the small protrusions 61 to the edge of the facing surface is also shorter than the height H0 of the ROM 80. Further, the distance L2 between the small protrusions 61 is also smaller than the width W of the package of the ROM 80.

In this embodiment, the portion extending from the transparent plate 60 and the small projection 61 make the drawer 3
Although the cable can be pulled out from 3, the control element such as a ROM cannot be passed through. However, besides forming such small projections 61, the transparent plate 6
It is possible to make the opening diameter small by merely protruding the edge of “0” inward from the outlet 33 so that a control element such as a ROM cannot pass through. Further, even if the edge of the outlet 33 itself is formed with irregularities, the cable can be pulled out while a control element such as a ROM cannot be passed. Also, as shown in FIGS. 5 and 6,
The edge of the outlet 33 itself may be a normal recess, and a separate adapter 34 formed of resin or the like may be attached. The adapter 34 has a groove 34a formed in the peripheral edge thereof, which is fitted into the edge of the outlet 33, and a protrusion 34b similar to the small protrusion 61 described above is formed inside.

The end of the side wall 21d of the lower case member 20 facing the drawer opening 33 is bent inward and downward, so that the flat cable 50 comes into contact with the bent portion as shown in FIG. The flat cable 50 is hardly damaged. On the other hand, locking structures 70 are formed on the side walls of the lower case member 20 and the upper case member 30 between and on both sides of the two concave portions 31d1 and 31d1. As shown in FIG.
Locking pieces 72, 72, 72 formed by extending strips from the side wall 31 of the upper case member 30 and tips of the locking pieces 72, 72, 72 formed on the side wall 21 of the lower case member 20 are inserted. Of a locking piece 72 having a crank-shaped cross section.
a enters the slit and is locked at the bent portion. The continuous portion from the side wall 31 is formed with an outer elliptical aperture 72b for reinforcement.

In the present embodiment, the locking structure 70 is formed by the locking pieces 72 and the slits 71, but the side walls 21d and 31d where the draw-out port 33 is formed are opposed to the separating direction. If so, it can be appropriately modified.
In addition, in order to fix the game control board 40, the lower case member 2
Female screws 24 are attached to the four corners of the bottom wall 22 at the four corners. In addition, the game control board 40
In order to further screw the upper case member 30 while screwing the screw, the lower end is formed with a male screw and the upper end is provided with a mounting stay 25 formed with a female screw.

Next, the operation of this embodiment having the above configuration will be described. First, the transparent plate 6 is provided on the back surface of the upper case member 30.
0 is attached. Then, the transparent plate 6 is provided in the drawer opening 33 portion.
The edges of 0 overlap and become the edge of the outlet 33, and the small projections 61 project from the edge at predetermined intervals. On the other hand, the game control board 40 is accommodated inside the lower case member 20 and the female screws 2 at the four corners are inserted therethrough.
4 is screwed with a male screw of the mounting stay 25.
Then, the game control board 40 is tightened and fixed to the female screw 24 at the body part of the mounting stay 25. Thereafter, the flat cable 50 is connected to the lower case member 20.
And is led out through the side wall 21d, and further covers the upper case member 30 from above.

At this time, the two flat cables 50,
50 is passed between the three locking pieces 72, 72, 72, and the tips 72a of the locking pieces 72, 72, 72 are connected to the lower case member 20.
Is inserted from the outside into the slits 71, 71, 71 formed in the side wall 21d. When the upper case member 30 is put on the lower case member 20 so that the crank-shaped bent portion penetrates the slits 71, 71, 71, the upper case member 30 extends from the end portions of the side walls 21 a to 21 c of the lower case member 20. The provided guide walls 21a1 to 21c1 are connected to the upper case member 30.
And the upper case member 30 and the lower case member 20 are united without generating a gap in the abutting portion. In this state, the upper case member 30 is penetrated and fixed to the mounting stay 25 with screws.

When the upper case member 30 is overlaid on the lower case member 20, it must pass through the outlet 33, but the small projection 61 does not hinder the flat cable 50 so much that it comes into contact with the flat cable 50. Sometimes it only flexes slightly. Therefore, a sufficient extra gap is generated. However, an appropriate jig is inserted through the gap of the drawer port 33, and the ROM mounted on the game control board 40 is
As described above, even if the ROM 80 is removed,
Can be used by the small projection 61 and cannot be taken out. If the edge of the outlet 33 is made of only metal, the wall may be bent by a screwdriver or the like, and may be pryed open. However, when the transparent plate 60 is used, the wall is broken. Can be left.

Note that the flat cable 50 itself is connected to the game control board 40 via a connector 51 provided at the tip, but such a connector 51 is larger than the ROM 80, and must be passed through this connector 51. The drawer port 33 that is not to be used would allow the ROM 80 to pass through. However, since the drawer port 33 is formed at the joint between the lower case member 20 and the upper case member 30, the flat cable 50 can be passed through at the time of separation, and the drawer port 33 does not need to be enlarged unnecessarily. In addition, since the locking piece 72 is formed at the seam portion forming the drawer opening 33, the seam cannot be expanded and the ROM 80 cannot be taken out.

As described above, the lower case member 20 and the upper case member 30 form a box-shaped case, and the game control board 40
When a recess 31d1 for leading out the flat cable 50 is formed at the end of the side wall 31d to form the outlet 33, the transparent plate 60 is extended to the side of the outlet 33. In addition, since the opening diameter is reduced by forming a small protrusion 61 protruding inward, the flat cable 50 is easily led out while preventing the package of the ROM 80 as the control element from being taken out. be able to.
