Abstract

Abstract PURPOSE:To contrive a simpler construction, by a system wherein a cutting operation of a cutter and an operation of separating a thermal head from a platen roller are selectively performed by a single drive source which can be rotated forward and reversely. CONSTITUTION:When a drive source 4 rotates in the direction of an arrow A, a cam 9 rotates in the direction of an arrow A' through a gear 5, a belt 10 and a cam shaft 9a. With the cam 9 thus rotated, a thermal head 2 is moved upward against the force of a spring 11, so that the head 2 is separated from a platen roller 1. On the other hand, when the drive source 4 is rotated in the direction of an arrow B, a gear 6 rotates in the direction of an arrow B', whereby a cutter blade 3 is oscillated through a link 8 fitted to the gear 6 and a lever 7 connected to the link 8, thereby cutting a recording paper. Accordingly, a simpler construction and a lower cost can be contrived.
