Abstract

PURPOSE:To make it possible to more surely prevent transcription lag due to the kicking out of a blank form by providing a gap smaller than the thickness of the blank form between a pair of conveying rollers arranged just before the transcription position of a picture image on a photosensitive body drum. CONSTITUTION:A blank form P gets into between a driving roller 4 and a driven roller 5 at its tip, and being its conveyance. In this case, a roller 5 is lifted as far as difference between the thickness t to of the blank form and a gapdelta, and the blank form P is pressed between the rollers 4 and 5 by the elastic restoring force of a pressing spring 12, and conveyed to a transcription position. Next, when the rear end of a blank form P is fed out form between the rollers 4 and 5, the roller 5 is pressed against the roller 4 by the spring 12 to make peripheral surfaces of both end of the roller 5 abut on the peripheral surface of the roller 4. Since the movement of the roller 5 at the time of its pressing against the roller 4 is so minute as only difference between the thickness t of the blank form and the gap 8, the kick out quantity of the blank form P due to pressed feeding becomes less to make the kicking out of the blank form P give no effect to adsorption force at a transcription position. Thus transcription lag can be prevented.
