PURPOSE:To contrive a higher accuracy in positioning, by providing an arm on which is disposed a driven roller gear engaged with a driven roller intermediate gear. CONSTITUTION:To feed a paper 38 backward, a knob 5 is rotated in the direction opposite to the direction of an arrow A, whereby a pulse motor gear 3, a first intermediate gear 6, a second intermediate gear 8, driving rollers 10, driven rollers 13, paper-feeding rollers 29, 34 and the like are reversely rotated. After returning the paper 38 to a deisred position by this operation, printing is restarted. To detach the paper 38 from a printer or to position the paper 38, a support shaft 14 for the driven rollers is energized upward, whereby left and right arms 17, 9 are moved upward by respective springs 24, 23, and the paper 38 can be released from a clamped state. |
