To provide a pachinko game machine which can improve the operability in the games.

An operation handle 8 is constituted of a handle base 26, a ring holder 27 and a face cover 28. A rotary encoder 30 and an encoder gear 31 are inside the body part 26a. A turning degree detection part 34 is provided on the body part 30a of the rotary encoder 30. A ring gear 27h is formed at the center part of the rear of the body part 27a. The ring holder 27 is formed in such a shape that it can maintain the attitude at any position wherever it is stopped in the turning thereof centered on an insertion hole 27i. A contact sensor 35 is mounted on the body part 27a. A contact sensing processing part 43 shifts the detection value of the degree of turning of the turning degree detection part 34 to the initial value at the 'half striking position' in the striking force of the pachinko balls 7 encountering the state of the contact sensor 35 which fails to sense the touching of the ring holder 27 by the players for 30 sec.
