Abstract

PURPOSE: To remove undesirable effects caused by residual images by applying a stated bias to the image pick-up surface after completing read operation in a picture pick-up device.
CONSTITUTION: Read operation enters the positional signals of (Xi, Yi) corresponding to a character position into shift registers 16 and 18 by means of position specification circuit 15, adds the signals to vertical and horizontal scanning signals respectively through D/A converters 17 and 19 and enters the added result to deflecting circuits 10 and 13, so that the section of the stated character is read out. Generation of electronic beams is stopped accompanied with the completion of reading and then motor starts access. After radiating character board 1 for a stated exposing period by means of laser source 3, laser source 3 is set to off and the section to be read out successively is erased. After confirming the completion of erasing and access, laser source 3 is set to on again, so that exposure starts and then reading starts after exposute for a stated period.
