PURPOSE:To perform exposure scan control with a simple constitution, by controlling a reciprocating means for exposing an original with time on the basis of a pulse counted value. CONSTITUTION:A CPU counts clock pulses to access an ROM and reads and executes a program successively to output a sequential control signal from an output device. Then, the reciprocating means for exposing the original under optical system forward movement and backward movement clutch control, etc., by control signals 1theta3 and 2theta4 from the output device with time is controlled. Therefore, the simple constitution which eliminates the need for a limit switch, relay, etc., makes an exposure scan on the original. |
