<p>PURPOSE:To simplify the structure and prevent double feed by guiding the lower edge part of a transfer paper sheet into the nipping part between rollers by a guide member and holding the paper sheet in an aslantly arranged state on the outer peripheral surface of a reverse roller. CONSTITUTION:When a guide roller 33 is revolved in the reverse revolutional direction from the state where the lower edge part of a transfer paper sheet 36 is placed on the upper surface of a guide plate 41, the guide plate 41 revolves around a supporting shaft 40. Accompanied with the revolution of the guide plate 41, the lower edge part of the copying paper sheet 36 is held in an aslantly arranged state on the outer peripheral surface of a reverse roller 34. When the feed roller 33 is revolution-driven in the paper feeding direction, the reverse roller 34 is followingly revolved, and the transfer paper sheet 36 in the foremost row intrudes into a nipping part 39. Further, when the second or the succeeding transfer paper sheet intrudes into the nipping part 39, the following revolution of the reverse roller 34 is suspended. Then, the transfer paper sheet 36 in the foremost rank is sent into a transfer part side by the feed roller 33, and the intrusion of the second or the succeeding paper sheet into the nipping part 39 is suppressed by the reverse roller 34.</p> |
