DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for mounting a control circuit board for controlling a game operation by mounting various electronic components used in a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art As is well known, gaming machines such as pachinko machines have become more and more popular in recent years. In particular, game machines such as large prize devices, various display lamps, and sound generation devices arranged on a game board are provided. Things with complex behavior are preferred. Such a pachinko machine with a complicated game operation is controlled by an electronic control circuit such as a microcomputer, so that a storage case containing a control circuit board is provided on the back of the pachinko machine. Installed. This storage case is formed by pressing a steel plate material, which is generally a conductive material, in order to prevent external noise.

In such a storage case, illegal operations such as illegally replacing a ROM provided on the control circuit board, or connecting a jumper wire to the control circuit board from the outside and inputting an illegal signal, etc. In order to prevent this, a sealing paper made of a material that is not easily peeled off and cannot be reused has been attached to the storage case. However, recently, there has been a case where a forgery is performed by forging the sealing paper itself. In such a case, there is a problem that the appearance of the storage case does not indicate whether or not the fraud has been performed. Was.

For this reason, as proposed in, for example, Japanese Utility Model Laid-Open No. 5-7282, "the interior of the cover can be visually recognized, noise resistance is increased, and the manufacturing cost is reduced. For the purpose, a pachinko machine comprising a printed wiring board provided with electronic components for controlling the operation of the pachinko machine, and a cover mounted on the printed wiring board so as to cover the electronic components. The cover is composed of a cover body formed of a transparent member and an electromagnetic shield provided inside, outside or inside the cover body and having a large number of holes. "

However, the cover proposed in Japanese Utility Model Laid-Open Publication No. 5-7282 requires that the cover body be formed in a rectangular container shape with a transparent material. The electromagnetic shielding member to be provided on the outside is useless unless it is grounded to the bottom cover or the like. Becomes very complicated, and the assembling work of the cover becomes difficult.

Therefore, the present inventor has repeatedly studied how to make this type of storage case easy to manufacture and assemble while improving the noise resistance while allowing the inside to be visually recognized. As a result, the present invention has been completed.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide high noise resistance and to facilitate its manufacture and assembly. Of course, you can see inside,
In addition, an object of the present invention is to provide a storage case for a control circuit board in a gaming machine capable of displaying the source of the gaming machine, the date of manufacture, and the like, with a simple configuration.

In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments. A storage case 10 that houses a control circuit board 20 on which electronic components are mounted and is attached to the gaming machine, and is attached to an upper surface of the storage case 10 formed so as to visually recognize a storage space R for the control circuit board 20. A storage case 10 having a seal 30 formed of a transparent material and having characters or the like in advance, partially having an opaque portion 31 for a character or the like to be written later. It is.

[0009]

With the above construction, the storage case 10 according to the present invention is formed so that the inside of the storage space R for the control circuit board 20 can be visually recognized. In 10, there is provided a seal 30 which is affixed to the cover plate 13 and partially has an opaque portion 31 for a character or the like to be written later, and is formed of a transparent material and has a character or the like written in advance. I have. This seal 3
0 is different from a sealing sticker attached over the lower case 11a and the upper case 11b and the like, but by attaching this to the cover plate 13, the storage case 10 or a game using the same is used. Information such as the source of the machine and the date of manufacture can be displayed.

As shown in FIG. 4, for example, various frames and characters are written on the seal 30. The contents of these characters and the like change variously. Since the seal 30 is formed of a transparent material, it is possible to reliably view the interior of the storage space R even after passing through the seal 30.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a storage case according to an embodiment of the present invention;
Reference numeral 0, as shown in FIG. 1, mainly includes a case main body 11 forming a storage space R for storing the control circuit board 20, and a cover plate 13 integrated on the upper surface side of the case main body 11. .

The storage case 10 is formed so as to allow the inside of the storage space R for the control circuit board 20 to be visually recognized, as will be described.
On the upper surface, an opaque portion 31 for a character or the like to be written later is partially provided, and a seal 30 formed of a transparent material and having the character or the like written thereon is attached thereto.

As shown in FIG. 1, the case body 11 is divided into two parts, a lower case 11a and an upper case 11b. And is formed of a metal material exhibiting an electromagnetic shielding effect. Lower case 11
a is mounted on a game machine such as a pachinko machine, and has holes for mounting the holes and a number of air holes 14 for radiating heat of the control circuit board 20. Since the upper case 11b is attached to the lower case 11a after the control circuit board 20 is housed, mounting holes and the like are formed therefor.

The upper case 11b is
Is attached to a game machine, and is located at a portion which can be directly seen from the outside, and is formed from a metal material similar to that of the lower case 11a by a slightly improved mold of the conventional mold. That is, a large number of see-through openings 12 are formed in a portion on the surface side of the upper case 11b, and between these see-through openings 12, as shown in FIG.
A part of the metal material is used as the grid 15. Of course, the upper case 11b is also provided with mounting holes and projections for fixing the lower case 11a to the lower case 11a, and the ventilation holes 14 are formed on the side surfaces.

In the upper case 11b according to the present embodiment, the central opening 12a of the multiple transparent openings 12 is formed.
Has a larger opening area than the others, and specifically, has substantially the same area as a seal 30 described later. That is, as shown in FIG. 4, for example, various frames and characters are written on the seal 30, and the contents of these characters and the like change variously. Thus, the visual recognition in the storage space R can be reliably performed even from the central opening 12a. In other words, if the seal 3 of the upper case 11b
Assuming that a grid 15 exists at the corresponding part of 0,
The storage space R is determined by the characters of the grid 15 and the seal 30.
Since it is difficult to visually recognize the inside, the upper case 11b corresponding to the seal 30 is set as a complete opening where the grid 15 does not exist.

As shown in FIG. 3, a cover plate 1 made of a transparent or translucent material (specifically, synthetic resin) is formed on the upper or inner surface of the upper case 11b.
The cover plate 13 completely covers each of the transparent openings 12 (including the central opening 12a). A plurality of mounting pins 13c are integrally formed on the periphery of the back surface of the cover plate 13 according to the present embodiment, and each of the mounting pins 13c is inserted into each of the mounting holes 11c on the upper case 11b side so that the upper case By melting the head protruding from 11b, the cover plate 13 is fixed to the upper case 11b.

In the cover plate 13 of this embodiment, FIG.
As shown in (1), a convex frame 13a is integrally formed at a position corresponding to the above-described center opening 12a, and the surface inside the convex frame 13a is used as a seal sticking portion 13b for the seal 30. . In other words, the seal 30 is stuck on the seal sticking portion 13b. In order to ensure the sticking, the convex frame 13a is used as a target or a guide while the seal 30 is attached to the seal sticking portion 13b. This allows positioning. Note that a large number of ventilation holes 14 are also formed in the cover plate 13 of this embodiment, and these ventilation holes 14 are formed at positions facing one of the transparent openings 12 on the upper case 11b side.

By the way, the seal 30 is different from a seal seal affixed between the lower case 11a and the upper case 11b and the like, and the seal 30 is provided for the storage case 10 or a gaming machine using the same. It indicates the source, date of manufacture, etc., and is made of a transparent material. And, in this seal 30,
As shown in FIG. 4, a manufacturer's name, a notice, etc. are printed, and in the illustrated example, an opaque portion 31 is formed in a part thereof. The opaque portion 31 is, for example, stamped with a model name composed of characters, symbols, and the like that are different for each gaming machine.
1 is set as a background so that it can be visually recognized well. In this sense, the opaque portion 31 in this embodiment is printed as a white background.

In the storage case 10 according to the present embodiment configured as described above, the case body 11 for forming the storage space R for storing the control circuit board 20 is formed of a metal material. The main body 11 itself exerts a shielding effect against electromagnetic waves, and
Of course, the grounding effect is exhibited only by fixing the case main body 11 to the gaming machine side. In addition, the manufacture itself of the case body 11 is performed by the respective transparent openings 1 described later.
Since it is sufficient to use a mold similar to the conventional case body except for the formation of 2, the case is extremely easy.

In particular, in the case body 11, when a large number of transparent openings 12 are formed on the upper surface side, the lattice 15 is formed by leaving a metal material between the transparent openings 12. Lattice 15 is upper case 1
Electromagnetic shielding is performed on the upper surface side of 1b. Thereby, even if the case main body 11 has a large number of see-through openings 12, its noise resistance is sufficient.

Since a large number of see-through openings 12 formed on the upper surface of the case body 11 are covered by a cover plate 13 made of a transparent or translucent material, the storage space passes through the cover plate 13 and the see-through opening 12. The situation of the control circuit board 20 and the like in R can be easily visually recognized. In particular, since the cover plate 13 is formed in a flat plate shape, the manufacturing itself of the cover plate 13 is very simple, and the positioning and attachment of the cover plate 13 to the case body 11 are very easy. Has become. That is, the cover plate 13 is attached to the case body 11 by, for example, bonding with an adhesive applied to the upper surface of the case body 11 or, as illustrated in the embodiment, protruding from the back surface of the cover plate 13. Each mounting pin 13c that has been set is attached to the mounting hole 11c on the case body 11 side.
This can be easily performed by fusing the protruding portion after passing through.

Further, in the storage case 10 according to the present embodiment, a large number of transparent openings 12
Is formed, and even if the opening area of each of the transparent openings 12 is made sufficiently large, these transparent openings 12 are covered by the flat cover plate 13. Tools and various objects do not enter the space R.

As described above, the storage case 1 according to the present embodiment.
The reference numeral 0 indicates that the noise resistance is improved by a simple structure, and the status of the control circuit board 20 in the storage space R can be easily visually recognized from the outside.
Its manufacture and assembly itself is also very easy.
