Description

  The present invention relates to a gaming machine including a casing having a frame structure and a face plate.

Conventionally, in this type of gaming machine, specifically, a slot machine, a wooden member is used for a casing. However, a change from a wooden member to a resin member has been studied from the viewpoint of depletion of wood resources and environmental protection, as well as from the viewpoint of economy and convenience of handling (for example, Patent Document 1).
In addition, in the game hall where the slot machine is placed, the game machine is frequently changed to change the game content to a different one, referred to as replacement of a new machine. At that time, the parts that do not affect the game content change such as the case and the payout device called the hopper unit, and the outer case are used as they are, and the game content such as the control device and the rotating reel is used. A so-called separation type slot machine is used in which only a part to be controlled is used as an exchange unit, and only the exchange unit is changed to a new exchange unit (for example, Patent Document 2).

However, in the conventional gaming machine described above, when trying to reuse parts including the housing of the gaming machine after use, the screw tightening portion is liable to be fragile due to the nature of the resin in the resin housing. There is a first problem that the resin casing cannot be used if the portion is damaged.
Moreover, in the case of the housing | casing which consists of a conventional wooden member, since the screw was screwed in using the drill in the appropriate position, without providing a screw hole, the fixing position of the screw could be set freely. However, in the case of a casing made of a resin member, if the screw is screwed into an appropriate position like a wood member, the resin member is broken, and thus it is necessary to provide a screw hole at a predetermined position. For this reason, there is a second problem that it is not easy to change the design, for example, it is difficult to change the fixing position of the screw by changing the part shape because the screw hole is tied to the set position.

In addition, when the casing is integrally molded with a resin product, if a fastening portion that becomes a screw hole is created, there is a third problem that the molding process becomes complicated and manufacturing becomes difficult.
In addition, since the case is large in size, if it is going to be integrally molded with resin, it will take time to cure, and it must be selected with the property of less distortion due to temperature changes. In other words, there was a fourth problem that material selection was difficult.
Further, in a so-called separation type slot machine having an exchange unit as described above, a casing that does not affect the change of game content is used repeatedly, but the exchange unit is made of resin. If the screw is fixed to the housing many times, the screw is repeatedly tightened, and the screwing portion becomes brittle and easily damaged, and the entire housing cannot be used. There was a problem.

Also, in conventional gaming machines, as a countermeasure against so-called radio wave gotling, a radio noise prevention member such as an aluminum sheet material for suppressing the influence of external electromagnetic waves is attached to the inside of the case after the case is completed. It was. There was a sixth problem that the work of attaching the aluminum sheet material to the inner surface of the completed box-shaped housing was not easy.
The above gaming machine is a slot machine that uses a disk-shaped game medal as a game medium, but the game content is similar to the slot machine, in which a rotating reel with symbols arranged around it is rotated and displayed. However, even a so-called parrot that uses a spherical pachinko ball as a game medium has the same problems as described above when a resin casing is used.
