[Conventional technology]

The types of coin game machines have diversified in recent years, but in short, the pachinko machine can be started by inserting a coin and the pachinko machine enters a specific prize hole, or a game with a large number of prize holes. In game machines that do not use pachinko balls, games such as clay pigeon shooting or ball games are played electrically or mechanically to challenge the player's skill or luck. It is structured so that coins are given out as prizes according to the player's score.

[Problems with conventional technology]

In such a coin game machine, there is a slanted gutter for guiding coins connected to the coin slot, a prize coin holding cylinder, a leaf box for storing coins overflowing from the holding cylinder, etc., for processing the inserted coins and for giving them as prizes. It requires a mechanism to release coins, but
Conventionally, these components were disclosed in Japanese Patent Application Laid-Open No. 51-141049, for example.

For this reason, molding and installation were time-consuming, wrinkles occurred at the mounting position, resulting in many defective products, and the manufacturing cost was high, making it unsuitable for mass production.

Additionally, coin game machines generally have an IC on a printed circuit board that constitutes an electronic circuit that specifies the game content and determines the outcome according to the rules. Wiring for electrical connection to a switch for detecting the presence or absence of coins, or a switch for detecting run-out of coins provided in the prize coin holding cylinder, or wiring for connection to a solenoid for ejecting coins. etc. are done in a complicated manner. However, when the wiring from the printed circuit board is spread out in many directions, there is a problem in that the printed circuit board itself cannot be easily removed or replaced.

[Means for solving problems]

The coin game machine of the present invention attempts to solve the above problems, and has a recessed part, a semi-cylindrical part, an upright plate part, and a storage space integrally formed in a set plate molded from a synthetic resin material. An auxiliary rail is fitted to form an inclined gutter for introducing coins, a semi-cylindrical lid is fixed to the semi-cylindrical part to form a prize coin holding tube, and a solenoid is fixed to the upright plate part. A coin ejecting section is assembled, a cover plate is provided in the storage space to form a coin storage box, and a switch for detecting passage of coins provided at least in the inclined coin introduction gutter and a switch provided in the prize coin storage tube are provided. A switch for detecting running out of coins and the solenoid are wired to a connector fixed to the set plate, and a printed circuit board constituting an electronic circuit is configured to be attached to and detached from the connector by sliding parallel to the set plate, and further The present invention is characterized in that the printed circuit board is connected to electrical components of the game machine main body via a connector provided on the opposite side of the printed circuit board to the connector.
