Abstract

PURPOSE:To enable simply and precisely operation setting of each part and fine adjustment, by successively generating sequential control signals necessary for control according to the program for carrying out each operation memorized in a memory device in advance. CONSTITUTION:The time limit value of each sequential operation of each copy size is memorized in advance as clock pulse number in semiconductor memory device 20, clock pulses are provided through AND gate AND 2 to counter 31 of counting device 30, this counted value is compared to the output value of ROM 20 in accordance decision circuit 32, consequently, the information is provided from ROM 20 in succession, and ring counter 42 is shifted. Original paper edge indication signal E is used as a synchronizing signal, exposure is started in accordance with this, and thus, the sequential operation is again synchronized.
