[Prior art and its problems] The winning condition is changed with respect to the winning device provided on the game board, the winning condition is relaxed when a certain condition is satisfied to increase the winning rate, or the relaxed state. Various operations such as stopping the operation are performed by the control means that is housed in the electronic circuit box. The circuit box that houses this electronic circuit is easily affected by noise from the outside, and in particular, in a pachinko machine, a large number of pachinko balls flow while colliding with each other in a plastic gutter. It is necessary to protect the circuit from At the same time, when the winning device is changed, this circuit box needs to be changed accordingly, so mounting on the pachinko machine,
It is desirable that it can be easily removed. In particular, in a so-called separation type pachinko machine in which the game board is detachable, it is necessary to replace the circuit box at the same time as the game board is replaced. Therefore, it is desired to be able to work quickly and easily.

In response to such a request, a device disclosed in Japanese Utility Model Publication No. 1-33104 has been proposed.
