PURPOSE:To permit the smooth movement by positively revolving, in the normal and reverse directions, a trailing shaft by the revolution in one direction of a driving shaft by the cam on a driving shaft side and the cam follower on a trailing shaft side. CONSTITUTION:A driving device 8 is equipped with a driving shaft S1 having a plurality of cams A-D fixed, trailing shaft S2 which revolves normally and reversely within a certain angle range through a cam, and a plurality of cam followers F1-F4 fixed onto the shaft S2. Said cam follower F1 receives the action of the cam A only, and the cam follower F2 receives the action of the cam B only, and similarly the cam follower F3 receives the action of the cam C only, and the cam followers F4 receives the action of the cam D only. Therefore, the normal and reverse revolution of the trailing shaft are cetainly performed, and smooth rotary movement is permitted.
