ABSTRACT:
The present invention provides a carriage reciprocating mechanism permitting easy reversal of the traveling direction of a carriage without changing the rotating direction of a motor or the traveling direction of an endless belt, and without rotating of the carriage itself, when the carriage reaches the end point of travel. The carriage can reverse the traveling direction thereof at the end point of travel by movement in only one direction of an endless belt stretched between a driving pulley arranged at one end of the frame and a follower pulley arranged at the other end thereof. Particularly, a reciprocating mechanism of a sheet-cutting device may have a carriage or a tool post provided allowing movement across a sheet to be cut relative to a frame. A rotary blade of the sheet-cutting device is supported by bearings on the tool post. A fixed blade of the sheet-cutting device can be arranged so as to come into contact with the rotary blade, and cutting the sheet with the assistance of the rotary blade and the fixed blade upon travel of the tool post.
