ABSTRACT:
An apparatus for controlling a transporting speed of a second transporting mechanism which is connected to a first transporting mechanism equipped with a speed sensor for detecting transporting speed of the second mechanism and a position sensor for detecting a position of a sheet being transported by the first and second transporting mechanisms. The second transporting mechanism is controlled by a first control for maintaining a predetermined speed basing on the information of the speed sensor when a sheet is not in both the first and second mechanisms which is detected by the position sensor, and when a sheet is in both the first and second sensor, receives the second control based on the control of memory contents in the first control. The first control is arranged to control a revolution speed of a driving motor by converting the time when the driving motor in the second mechanism is turned on and off, while the second control is arranged to control the second transporting mechanism for lowering a speed under a predetermined speed when a transporting speed of the second transporting mechanism exceeded the predetermined speed.
