PURPOSE:To reduce the time for deceleration and acceleration in a reciprocating operation to a minimum, to make a quick return and to realize it by a comparatively small mechanism. CONSTITUTION:A base 1 on which a guide 10 is formed, hammers 3 which are installed at both ends of the base 1, a moving object 7 which is set on the guide 10 and a detection device which detects the position of the moving object 7 are installed in a reciprocation driving gear. The hammers 3 are driven on the basis of an output signal from the detection device, and the moving object 7 is returned and operated by the hit of the moving object 7 by the hammers 3. |
