However, the present invention is not limited to this. 18, or the transparent conductive layer 40 may be formed on the front surface of the cell plate 23 (the front surface of the game board 18).
In the first to third embodiments, the ground terminal 73 is fixed to the main set 70. However, the present invention is not limited to this. For example, the ground terminal 73 may be fixed to the rear surface of the front door 3.

In the first to third embodiments, the present invention is applied to one type of pachinko machine in which a jackpot operation is performed in conjunction with the occurrence of a jackpot. However, the present invention is not limited to this. The present invention may be applied to two types of pachinko machines or three types of pachinko machines. In the former two types of pachinko machines, the pachinko ball is opened in the special winning opening in the accessory when the accessory is opened when the pachinko ball enters the winning opening. A jackpot operation is performed based on the ball. In the latter three types of pachinko machines, the special winning opening is opened in conjunction with the occurrence of the big hit, and the big hit operation is performed based on the pachinko ball entering the special winning opening when the special winning opening is opened. Will be
