Abstract

PURPOSE:To prevent paper unevenness from occurring by counting a conveying pulse signal due to paper movement, reading out a conveying time value to be adapted at each count and rewriting memory one after another, and when it cannot be rewited even after the time, making a feed roller contact or separate to or from the paper. CONSTITUTION:When a paper tip is passed through beneath a feed roller of a paper discharge tray, a drive pulse is generated, pressing this feed roller to a sheet of paper via a flip-flop circuit 17, a drive circuit 19 and a solenoid 7. Simultaneously, a conveying pulse signal out of a pulse generating device by paper movement is counted by a counter circuit 14, and a control circuit 18 reads a conveying time value to be adapted at each count out of plural conveying time value preset, whereby a set value of a timer setting circuit 15 or time value memory is rewritten, and simultaneously it is counted by a timer circuit 16, and when the memory cannot be rewritten even after the elapse of setting conveying time, the feed roller is made contact or separate to or from the paper. Thus, paper unevenness is prevented from occurring without bending the paper.
