Abstract

PURPOSE:To perform stable feeding corresponding to various kinds of sheets by constituting a titled device of the 1st and 2nd rollers for separating and conveying the sheets on a sheet placing table by each sheet in such a way that the clearance between these rollers is adjusted. CONSTITUTION:When the operator sets a sheet number counter and depresses a copying button, separating and delivery rollers 53, 52 revolve and the uppermost sheet original 50' is conveyed by draw-out rollers 54, 55, and is once stopped in the stand-by position. At the same time, a repeat drum 66 starts revolving, and is slit-exposed. A gripper 71 clamping the leading end of the original 50' discharges the original 50' onto an original tray 92 when the sheet number counter is 1. This original is fed by press rollers 45, 46. The conveying speed of the rollers 54, 55 is higher than that of the delivery roller 52 to create a clearance between the leading end of the 2nd original and the trailing end of the 1st original 50'. The 2nd original is discriminated from the 1st one and is once stopped similarly, after which it is delivered again. In this way, the stable feeding is accomplished.
