Abstract
An apparatus for driving a CCD-sensor used in a reader for facsimile. Charge storage time of the CCD-sensor is determined on the basis of detected quantity of light for illuminating a document to be read. The CCD-sensor is driven periodically at a time interval corresponding to the storage time thus determined so that an output signal resulting from the photoelectric conversion effected by the CCD-sensor may remain steady regardless of variations in the quantity of illuminating light.
