Abstract
PURPOSE:To feed paper to automatically correspond to the position of a picture by providing a means which sets the timing roller on or exposure start signal generation timing being based on a measured value. CONSTITUTION:Paper feed and exposure timing starts an exposure by a laser beam 2 after the time (t) detecting a point end of paper, fed from paper feed rollers 4a-4c, by the first paper sensor 5. And setting a timing roller 6 so as to be turned on after the time T from this exposure start, this time T is automatically corrected. A control unit provides various input ports 22 and output ports 23 for a CPU 21, controlling the information of every kind. A submemory 24 has memory space of 10 byte basically storing measured data of 10 times sampling, and a main memory 25 has memory space of 1 byte storing timing data turning on the timing roller.
