<p>PURPOSE:To stably absorb a differential speed between conveying systems by interrupting fixed speed conveyance and performing conveyance by a fixed voltage control or fixed current control and the like while a sheet-state conveyed object is placed over the other conveying systems being put therebetween. CONSTITUTION:Discharging paper from a discharge roller in a copying machine main unit 10, the paper passes through an acceptance part 41 of a sorter 50, conveying part 54 driven by a conveying motor 541 and a gate part 53 lifted by a gate motor 542, being successively fed to each bin 521. This conveying motor 541 is driven in a fixed speed by a CPU with a pulse signal from a motor pulse generating part, but when the paper is conveyed over the discharge roller of the copying machine main unit 10 and the conveying part 54, the motor 541 is switched from a fixed speed control to a fixed voltage control. Next when the motor 541 is returned to the fixed speed control, under the condition with a conveying speed not exceeding the predetermined upper limit speed, driving voltage in the time of fixed speed control, stored in a memory means, is supplied. By the control thus obtained, a speed difference between conveying systems can be stably absorbed.</p> |
