Japanese Patent JP3913344

B2

PROBLEM TO BE SOLVED: To make preventable a substrate, etc., from being illegally fitted by providing a detecting means arrangement part in which a specified prize-winning ball detecting means is not removed from the outside of a substrate box and connecting the specified prize-winning ball detecting means to a game control substrate in a state set in the detecting means setting part so as to able to input a signal.
SOLUTION: A role object control circuit unit 200A pressurizes a holding member 38 toward the holding holes 122a and 123a of a game board 1 and a prize-winning ball aggregation cover 120 in a state where a pattern start switch 40 is inserted into a pattern start switch inserting part 121, inserts it and fixes it on the rear surface of the game board 1. In this state, the inner peripheral surface of a passage hole becomes a successive state with the inner wall surface of the guide path inside the prize-wining ball aggregation cover 120 in the pattern start switch 40 and a prize- winning ball passes through the passage hole of the pattern start switch 40 in a process where it flows-down the guide path on the rear surface of the game board 1. The substrate box 20 is fixed by a lid member 20A and a base member 20B by crews and fixed by putting through a one-way screw from a lid side sealing member side to a base side sealing member 39 side.
