Abstract

PURPOSE:To improve the read precision, by reading or recording only the picture signal obtained in the stable operation region of the response characteristic of a pulse motor. CONSTITUTION:Picture signal a1 obtained by scanning of the reader is prevented from being written in buffer 5 when the original is moving. Next, the second picture signal a2 obtained in the stable operation region is input to input terminal 1, and buffer write enable signal (b) is input from input terminal 2 to control circuit 4. Then, a signal which sets buffer 5 to the write permission state is output to buffer 5. Picture signal a2 of one-line components obtained in the stable operation region is stored in buffer 5 temporarily. Control circuit 4 outputs step pulse (c) to the step motor to rotate the step motor, and the original is moved to the next line.
