<p>A triple-roller device having paper-feeding and sending driven rollers, a paper-feeding guide section and a paper-reversing guide section are provided on both sides of a driving roller that rotates in one direction. The paper-reversing guide section has an upper guide section that corresponds to an upper portion from a mid-point of its curved section, and the upper guide section is driven by a solenoid, and allowed to shift. The upper guide section is allowed to shift to a position at which its end on the paper-feeding and sending side is placed between the driving roller and the paper-feeding driven roller, as well as to a position at which it is placed between the driving roller and the paper-sending driven roller. A sheet of paper, which has entered the paper-reversing guide section, is held by a paper-holding roller device. It is possible to provide a shorter paper interval with respect to the paper-sending operation from the paper-reversing guide section.</p> |
