Abstract

PURPOSE:To prevent the break of a sheet lacking firmness, by releasing the squeezing force of a feed roller to the sheet after the tip of the sheet fed so as to close adhere to a photosensitive drum for transcription has a contact with the drum. CONSTITUTION:A sheet 1 on a sheet cassette 2 is held between up and down transcription forward feed rollers 5 and 4 and fed to a transcription drum 11 by a paper feed roller 3. The sheet 1 receives a contact transcription at the part of a charger 12 and is discharged to a paper discharge tray 15 after passing a fixing device and through a separating part 13. The tip of the sheet squeezed by rollers 4 and 5 has a contact with the drum 11, and a solenoid 9 becomes inactive in the lapse of a certain period of time. Then a lever 7 tilts clockwise and centering on a shaft 6. As a result, the space between the rollers 5 and 4 increases to release the squeezing force of the sheet 1. Accordingly a sheet which lacks firmness is not forcibly fed to prevent the break of the sheet.
