Abstract

In a method of driving an image sensor comprised of a plurality of image sensor chips to sequentially deliver image outputs from the image sensor chips, start signals are initially applied to all of the image sensor chips at the beginning of the drive timing, a shift clock is applied to only each one of the plurality of image sensor chips which is so selected as to deliver an image output, and image outputs are picked up from the individual image sensor chips by sequentially applying shift clocks to selected image sensor chips so as to provide a continuous sensor output signal, whereby no noise is superimposed on the sensor output signal and the quality of images in the image reader, facsimile equipment, OCR equipment and the like can be improved.
