TECHNICAL FIELD The present invention relates to a control board case for a game machine having a hermetically sealed structure in which a control board for the game machine is housed.

[0002]

BACKGROUND ART In recent years, game machines such as pachinko machines have become shorter in life cycle due to fierce competition not only in development of game machine manufacturers but also in sales of game halls. Then, when a new game machine is developed and provided to the market in such a short life cycle, the number of discarded game machines that are no longer used due to replacement with a new game machine in the game hall
Naturally, the results will increase, so it is considered important to clarify the responsibility for the disposal of game machines.

By the way, since the gaming machine main body, the gaming board, etc. are conventionally provided with the logo of each gaming machine maker, etc., the gaming machine as a whole clarifies the responsibility for disposal. Although it is possible, when disposing of the gaming machine, it goes without saying that the gaming machine is disassembled and the gaming machine body, gaming board, control board case, and other parts are disposed of separately. However, for example, a game machine maker having a similar structure such as a control board case, etc. is distinguished after the game machine is disassembled. It is difficult to manage, and it is necessary to clarify the responsibility for disposal by managing it by some means.

Particularly, since the control board case is an important one for accommodating and arranging the control board for controlling the operation of the game machine, not only to clarify the responsibility at the time of disposal, but also
Even while the gaming machine is being used in the hall,
Needs to be managed.

Therefore, for example, it is conceivable to manage the control board case by attaching an identification mark having some management information written on the surface of the control board case with an adhesive or the like. Just sticking with adhesive etc.
The identification mark may be exposed to dust, oil or the like in the outside air to be easily soiled or damaged, and it may not be possible to sufficiently exhibit its function.

As described in Japanese Patent Application Laid-Open No. 11-313967, etc., the control of a CPU and the like mounted on a control board housed in a control board case for the purpose of preventing illegal acts due to unauthorized modification It may be possible to manage the control board case by using the management information attached to the element, but the management information is used because the part to which the management information is attached deteriorates due to the heat generation of the control element. However, it is not always an effective measure.

[0007]

The present invention has been made in view of the above circumstances, and the problem to be solved is to display management information stably for a relatively long period of time. It is to provide a control board case of a game machine having a new structure, which is capable of.

It is difficult to tamper with the management information displayed on the management sticker 40, and it is possible to advantageously prevent illicit acts such as replacement of the main board case 10 itself. However, since it is possible to easily confirm such fraud, the main board case 10
It is also possible to advantageously prevent fraudulent acts of exchanging themselves.

Further, FIG. 5 shows an enlarged view of a main part of a main board case 44 as a control board case of the second embodiment of the present invention. The main board case 44 of the present embodiment is different from the main board case (10) of the first embodiment in that instead of the management sticker (40) for displaying management information, it is a bill-shaped information for displaying management information. A management card 46 is used as a display member. In the following description, members and parts having the same structure as in the first embodiment will be denoted by the same reference numerals as those in the first embodiment in the drawings, and a detailed description thereof will be given. Is omitted.

More specifically, the management card 46 is formed by processing paper, synthetic resin film or sheet, etc., into a predetermined size, and on one surface, the model name and manufacturing of the pachinko machine are manufactured. Management information such as a person's name, serial number, manager's name, and pachinko hall name is displayed as character information. The display of the management information on the management card 46 can be advantageously realized by, for example, a method of printing the management information on the management card 46 using a printer. And
The management card 46 is embedded in the main board case 44 with the surface on which the management information is displayed being positioned outside the main board case 44. In particular,
The management card 46 is embedded in the upper wall portion of the main board case 44, that is, the upper bottom wall portion 42 of the cover member 16, which is positioned on the front side when the main board case 44 is attached to a predetermined position on the back surface of the pachinko machine. As a result, the management information displayed on the management card 46 can be confirmed from the outside when the main board case 44 is attached to a predetermined position on the back surface of the pachinko machine.
There, the cover member 16 of the management card 46
For example, compression molding, in-mold molding, insert molding, injection molding using a two-color molding machine,
The fixed mold and the movable mold that make up the mold are configured in a nested structure, and a cavity structure is adopted so that the molding material adheres to the movable mold side when the molding material solidifies. After injecting the molding material into the cavity with the display member superposed, the movable mold is retracted to position the molding material on the surface of the fixed mold side of the fixed information display member and the fixed mold cavity. Simultaneously with the molding of the cover member 16 by a method of forming a gap with the inner surface and injecting a molding material into the gap, or by injection molding with the management card 46 positioned in a predetermined position in the mold. It can be realized advantageously.

In the main board case 44 having such a structure, the management card 46 is embedded in the cover member 16 so that the management information displayed on the management card 46 can be confirmed from the outside. The same effect as the first embodiment can be obtained.

Further, in this embodiment, since the management card 46 is embedded in the cover member 16, when the cover member 16 and the base member 14 are assembled, for example, a seal on which management information is displayed is covered. The step of sticking to the member 16 can be omitted.

Further, since the management card 46 is embedded in the cover member 16 because special equipment is required, it is easy to identify a person who has committed an illegal act.

Although some embodiments of the present invention have been described above in detail, these are merely examples, and the present invention is construed in a limited way by the specific description of the embodiments. Not a thing.

For example, it is possible to display the management information in the form of a bar code, so that more information can be stored.

It is also possible to display the management information by marking it on the inside of the control board case. The marking of the management information on the inside of the control board case can be performed simultaneously with the molding of the control board case, or It can be performed after molding the control board case. When the control board case is engraved after molding, it can be advantageously realized by using a laser or the like.

Furthermore, it is possible to provide a texture pattern in which the design changes depending on the difference in the refractive index on the bill-shaped information display member, thereby further advantageously preventing fraudulent acts of replacing the control board case itself. You can do it.

When an information display member for displaying management information is attached to the control board case, the information display member is used as a sticker and the sticker is directly attached to the control board case as in the first embodiment. You can wear it, but you can put the card-shaped information display member on the control board case,
Alternatively, a sticker larger than the card-shaped information display member may be attached to the control board case so as to cover the card-shaped information display member and its outer peripheral edge portion.

Further, it is possible to form the bill-shaped information display member by a thin metal plate, and in such a case, the management information is displayed on the bill-shaped information display member as management information. A method of engraving the information on a bill-shaped information display member using a laser or the like is preferably used.

In the second embodiment, the management card 46 is formed on the cover member 16 simultaneously with the molding of the cover member 16.
However, for example, a cover member having a recess opening on the inner surface side is prepared, and a management card and a member for filling the recess are sequentially accommodated and arranged in the recess, and then the recess is filled. And the cover member by ultrasonic welding, or by forming a stepped recess that opens to the inner surface side, and storing and arranging the management card in the deep bottom part, then removing the outside of the member that fills the recess. It is also possible to embed the management card after molding the cover member by a method of fixing the peripheral portion and the shallow bottom portion of the recess with an adhesive or the like.

Further, the specific structures of the sealing means and the control board case in the present invention are not limited to those of the first and second embodiments.

The management information on the gaming machine of the present invention is not only for clarifying the responsibility at the time of disposal,
For example, even if it is used for investigating the route or person in charge when illegally dumped, used for managing gaming machines only in the hall, or used for management for public safety departments, etc. Well, its use is not limited to that of the first and second embodiments.

Further, in the first and second embodiments, a specific example in which the present invention is applied to the case for accommodating the main board is shown, but the present invention accommodates other control boards. It is needless to say that the present invention can be applied to a case in which it is arranged, for example, a case in which a prize ball refund control board is housed and arranged.

Further, the present invention can of course be used in combination with a conventionally known method of adding management information.

In addition, in the first and second embodiments, a specific example of applying the present invention to a control board case of a pachinko machine is shown, but the present invention is applicable to gaming machines other than pachinko machines. It goes without saying that it is also applicable to the control board case.
