ABSTRACT:
A reciprocating device comprises an endless member such as a chain or a belt having a forward and a backward side spans and driven to circulate in one direction, a reciprocating member guided substantially parallel to both the forward and backward side spans of the endless member, engaging mechanism provided on the reciprocating member which selectively engages with the forward or the backward side span of the endless member, and a changeover mechanism for switching the engaging mechanism from either one of the forward or backward side span of the endless chain to the other at the preselected limit position of the reciprocation movement range of the reciprocating member. The reciprocating member moves according to the movements of the forward side span of the endless chain upon engagement of the engaging mechanism to the forward side span of the endless chain, and moves respectively when engaged with the backward side span of the endless chain. The reciprocating movement range of the reciprocating member is determined by the changeover timing of the changeover mechanism.
