ABSTRACT:
A photoelectric converter apparatus suitable for use as an optical pattern reader is disclosed. A CCD image sensor receives light reflected from a text having characters or graphic patterns marked thereon and stores charges proportional to the intensity of the reflected light. Unnecessary charges are transferred from the CCD image sensor to the shift register and are swept out during a time period other than a readout period for necessary data. The readout data which exactly reflects the data on the text is produced with a reduced sweep-out period.
