Main scan pulses are applied to a CCD charge accumulation type linear photosensor array to effect horizontal scan of a linear portion of a light image of an original document focussed on the array. The document is moved by one increment each time the array is scanned to effect vertical scan. Scanning is performed intermittently under control of a run length encoder. The main scan pulses are delayed while the document is moved by one increment when the encoder causes scanning to begin.
