Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pinball game machine typified by a pachinko game machine, a coin game machine, and the like.

[Conventional technology]

Among this type of pinball game machines, there are some that have been generally known for a long time, such as the
There is a device described in Publication No. 158785, in which a game board is detachably attached to the front frame of a pinball game machine, and only the game board on which the game device is installed can be replaced at the game parlor. It was designed to reduce the cost of replacement by reducing the number of parts to be replaced. On the other hand, in recent years, there has been a trend toward configuring game devices installed on game boards as electrical game devices that operate electrically, and providing a wide variety of games through electric and flexible movements. In that case, it is necessary to detachably attach to the pinball game machine a storage box that houses a circuit board for controlling the electrical game device provided on the game board. When replacing the game board with a game board equipped with a new electric game device, it is also necessary to replace the storage box with one that matches the model of the new electric game device.

[The problem that the idea aims to solve]

Therefore, when replacing the so-called detachable type pinball game machine in which the game board can be separated from the front frame described above at a game parlor, an electrical game device of the type desired by the game parlor is installed. The game board and the storage box containing the circuit board suitable for the model of the electric game device are shipped to the game hall. Objects may collide with the shipped storage box while it is being transported to the game arcade. However, if the connecting portion of the circuit board to the connection wiring is exposed outside the storage box in consideration of the convenience of connecting the connection wiring to the circuit board stored in the storage box, the If an object or the like collides with the connecting part, the connecting part is damaged during transportation, and even if it is assembled at a game hall, a defective electrical connection occurs and the electrical game device does not operate normally. Another drawback is that noise can enter through exposed connections, causing malfunctions.

In other words, in so-called separate type pinball game machines, the storage box is transported separated from the pinball game machine, and the connections to the connection wiring of the circuit board, which are particularly susceptible to damage, are damaged during transportation. It had the drawback of being damaged.

In view of the above-mentioned circumstances, the present invention aims to prevent as much as possible damage to the connecting portion of the circuit board to the connection wiring during transportation of the board box required in a so-called separate type pinball game machine.

[Means to solve the problem]

A pinball game machine according to the present invention includes: a front frame, a mechanism plate provided on the back side of the front frame, a game board detachably attached to the front frame, and a game board provided on the game board. a storage box that stores at least a circuit board for controlling the electric game device; and connection wiring that connects the electric game device and the circuit board, the storage box comprising: The present invention is characterized in that it is detachably attached to the mechanism plate and has a cover portion that covers a connection portion with the connection wiring of the circuit board in a stored state, and a wiring insertion opening through which the connection wiring can be inserted.

[Effect]

According to the present invention, the game board provided with the electric game device is detachably attached to the front frame side, and the storage box for storing the circuit board for controlling the electric game device is mounted on the mechanism board. Since it is removably attached to the electric game device, new games can be provided to players by replacing the game board equipped with the electric game device and the storage box at the game parlor. The cost can be reduced.

In addition, the connection portion between the circuit board and the connection wiring on the circuit board stored in the storage box is covered by the cover part of the storage box, and the connection portion of the circuit board stored in the storage box is covered by the connection wiring inserted into the wiring insertion hole provided in the storage box. The electrical gaming device and the circuit board are connected. As a result, when transporting the board box required for so-called separate type pinball game machines, it is possible to keep the connection part of the circuit board inside the storage box covered by the cover part of the storage box. Therefore, damage to the connection portion can be prevented as much as possible. Further, noise caused by static electricity or the like in the game parlor is prevented from directly invading through the connection portion.
