Abstract

PURPOSE:To simplify the constitution of a circuit and to eliminate the need for an external memory of a large capacity by providing a memory section storing a signal charge of each photosensitive picture element of (N-1) photosensing picture element arrays except the final row viewed in the subscanning direction, N pieces of photosensitive picture element arrays or all photosensitive picture element arrays at every photosensitive picture element array. CONSTITUTION:When a photosensitive picture element array 16 reads the 1st line of an original to be read, a memory section 18 holds a signal charge generated by photosensitive picture elements 12, 14... for one scanning time. After one scanning time elapses, the photosensitive picture element array 15 reads a 1st row and the photosensitive picture element array 16 reads a 2nd row. In this case, the memory section 17 does not hold the signal charge but transfers immediately the signal charge generated by photosensitive picture elements 11, 13... to a register 19. Since the information reading the 1st row for two times is obtained at the same time, the constitution of the circuit is simplified and an external memory of a large capacity is not required.
