PURPOSE:To alternately shift a transfer body at two positions by permitting the passing of a cam follower only in one direction in the first and second cam grooves and arranging each regulating member for introducing the cam follower into a communication cam groove in the shift in other direction. CONSTITUTION:When a cam follower 27 is shifted rightward and leftward alternately, said cam follower 27 is shifted along a lower cam groove 31 by the rightward shift and passes the regulation of a leaf spring 35A. The cam follower is introduced into a communication cam groove 32A, guided by the leaf spring 35A, by the succeeding leftward shift, and passes through a leaf spring 35B, and is introduced into an upper cam groove 30. Then, the cam follower 27 shifts rightward, guided by an upper cam groove 30, and passes through a leaf spring 35C, and is introduced into a communication cam groove 32B through the succeeding leftward shift, guided by a leaf spring 35C, and returns to the left edge part of the lower cam groove 31. Therefore, the cam follower moves vertically in one time through two times of reciprocation, and is suitably used for the horizontal shift of a disc film in a development device for the disc film. |
