However, for example, Japanese Patent Publication No. 58-20310 discloses a structure in which a cover plate is merely attached and detached, and a structure of a cover plate which covers a prize-winning device and a circuit box. Therefore, there is no function to protect the winning device or the circuit box. In addition, 4-1
In the device disclosed in Japanese Patent No. 1073, the wiring is covered with a prize winning device protection cover. Therefore, in order to carry out the wiring process, the operation cannot be performed unless the winning ball collection cover is removed. In addition, when the game board is shipped to the factory, a winning ball set cover and a winning device protection cover are required, so that the selling price of the game board becomes high.
In Japanese Patent Publication No. 55-13752, there is only one ball-shifting space for collecting winning balls, and no circuit box is provided. Further, Japanese Patent Publication No. 62-25391 and Japanese Unexamined Patent Publication No.
In Japanese Patent No. 9169, the circuit box and the wiring are not protected, and in order to attach and detach the wiring and the like between the circuit box and the winning device, it is necessary to work by removing the winning ball set cover. It is inconvenient when trouble occurs during business hours. On the other hand, if the members are arranged in a cluttered manner, it is difficult to detect an illegal alteration, and an illegal game may be permitted. In addition, if the arrangement of each member is poor, operability is poor, and there is a problem in assembling work and maintenance work.
