<P>PROBLEM TO BE SOLVED: To prevent degradation of image quality and occurrence of jamming in advance. <P>SOLUTION: The feeding operation of a leading sheet and a succeeding sheet is started in predetermined times Tp1 and Tp2 (Tp1<Tp2) from the vertical synchronous signal Vsync. The paper sheet feed starting time of a gate roller is a predetermined time Tg after the vertical synchronous signal Vsync, at the equal timing between the leading sheet and the succeeding sheet. When the time from the feeding operation starting time of a pickup roller to the paper sheet operation starting time of the gate roller is defined as the sheet set-up time, the sheet set-up time Ts1 for the leading sheet and the sheet set-up time Ts2 for the succeeding sheet are given by T0+Tg=Tp1+Ts1=Tp2+Ts2. Since Tp1<Tp2, Ts1>Ts2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
