PURPOSE:To support and feed cutform printing paper stably and positively, by normally supporting cutform at its lower end, and when the cutform is to be fed, the cutform is pressed by a tension roller against a feed roller, and then rotatably supporting a paper stopper which is temporarily retracted from below the cutform, by a control shaft. CONSTITUTION:A solenoid is excited by a printing signal from a main body of a printer. A movable iron core of the solenoid is consequently attracted and raised, and a control bracket 48 is rotated integrally with a control shaft 45 in a clockwise direction. By this rotation, a tension roller 38 protrudes frontwards out of a notched window 47, so that a lower end of a cutform 2 is pressed against the peripheral surface of a feed roller 16. Thereafter, due to rotation of the control shaft 45, a paper stopper 36 is rotated in a counterclockwise direction around a guide bar 158 against the force of a spring 40. A supporting part 36A of the stopper 36 is temporarily retracted from below the cutform 2. In this state, the feed roller 16 is rotated to feed the cutform 2 towards a platen 6. |
