Abstract
PURPOSE:To provide a simple construction, highly efficient sequential copying in electrophotography, copy sequence timing pulse is generated before the preceding timing pulse ends. CONSTITUTION:The clock pulse generator disk 43 contactly rotates with the light sensitive drum 9 to provide clock signal from the photo-counter 44. The clock signal is fed to the counter decoders 46 and 47 in the main and subsidiary timing pulse generators 51 and 52 to cause the timing pulse selectors 48 and 49 to generate timing pulse sequence corresponding to the former and latter copying sequences, which is then fed to the sequence instruction circuit 53. The circuit 53 which receives required detection signal generates a control signal through the interface 45 to produce a required number of copies by one time of exposure. Thus, the main timing pulse generator 51 enables to intiate the next timing pulse series at any moment while the subsidiary timing pulse generator 52 is generating timing pulse and feeding it to the circuit 53.
