Printer

Abstract

Abstract PURPOSE:To remove the tension of a printing paper thereby to prevent said printing paper from curling when said paper is left unprinted for a long time by reciprocating said printing paper not yet printed by a predetermined distance with use of a moving means after said paper is printed one page and cut to a predetermined size by a cutter. CONSTITUTION:In response to information from a detecting part 20b which identifies when a cutter is stopped driving, a control part 20c moves a roll paper 3a a predetermined distance which is not yet printed, and then moves the roll paper 3a the same predetermined distance in the opposite direction. In other words, the control part 20c has a function to drive a platen roller 2a in a forward and a rearward directions so that an end of the roll paper 3a at the position of a cutter part 8a is forwarded a predetermined distance and then retracted the same distance to return to the cutter part 8a. At this time when the roll paper 3a is retracted, it is released from the pressure contact with a curl removing rod 6a, and therefore it is deflected. Accordingly, the printing paper is prevented from curling when the paper is not printed for a long time.
