<p>PURPOSE:To permit the stable toner image transcription by properly maintaining the contact state between a paper and a photosensitive body by supporting a feed-in pin tractor onto a frame in free shift in the paper feed-in direction by urging said feed-in pin tractor in the reverse direction to the paper feed-in direction by a spring mechanism. CONSTITUTION:When a paper 4 is to be set onto a device, a feed-in pin tractor 1 is shifted in the paper traveling direction by an eccentric cam 20, and a spring mechanism 19 is released, and the paper 4 is set in the slack state. When paper is sent to copy the toner image on a photosensitive body onto the paper, the eccentric cam 20 is separated from a slide plate 18, and the feed-in pin tractor 1 is urged in the reverse direction to the paper feed-in direction by the spring mechanism 19, and the paper is applied with a tension. Therefore, the photosensitive body and the paper are attached by a proper contact pressure, and the stable toner image transcription is permitted.</p> |
