PURPOSE:To accomplish a high-speed and high-accuracy operation and to make function multiple by generating a coincidence signal in the case that the counted value of pulses generated in synchronism with the small specified amount of movement of a photosensitive body coincides with timing data, counting the signal and starting/finishing a copying process corresponding to counting data. CONSTITUTION:The counting data of the synchronizing pulse which is generated by one for every small specified amount of the movement of the photosensitive body 4 is compared with the timing data for deciding a copying process sequence. When they coincide, the coincidence signal is generated to update the timing data. The coincidence signal is counted by a counting means 21 and the copying process corresponding to the counting data of the counting means 21 is started/finished every time the counting data is switched. Thus, a copying device which is fitted to accomplish the high-speed and high-accuracy operation and to make the function multiple is obtained. |
