<p>PURPOSE:To eliminate the installation of a pair of auxiliary carrying rollers between a resist stopper and a photoreceptor by enlarging an oscillation stroke of a resist stopper with a moving member to. make the resist stopper go ahead and back into/from the paper carrying passage. CONSTITUTION:When a lower roller 51b of a pair of carrying rollers 51 is separated from an upper roller 51a, a moving member 56 makes a resist stopper 51 go ahead into the paper carrying passage A, and when the lower roller 51b pressure-contacts with the upper roller 51b, the moving member 56 makes the resist stopper 56 go back from the paper carrying passage A. Since the lower roller 51b of the pair of carrying rollers 51 can be therefor separated from the upper roller 51a under the condition that the resist stopper 52 goes ahead into the paper carrying direction A, a danger that a paper is curved large is eliminated. Furthermore, papers can be pinched by the lower roller 51b and the upper roller 51a and securely carried under the condition that the resist stopper 52 goes back from the paper carrying passage A. Consequently, installation of a pair of auxiliary carrying rollers in the downstream of the pair of carrying rollers 51 is eliminated.</p> |
