    摘要: An optical image sensor apparatus in which a plurality of photosensors arrayed in a primary scanning direction are scanned to produce readout signals. The plurality of photosensors are classified into a number of groups each including a predetermined number of the photosensors, wherein those photosensors occupying equivalently the same position in the different groups are combined in common. The outputs of the photosensors are sequentially and selectively scanned on a group basis to produce readout signal for each of the groups. To provide a scanning readout operation at an increased speed, an integrating circuit is provided for each of the photosensors exchangeably for each group. The outputs of all the photosensors belonging to a given one of the group are simultaneously supplied to the respective integrating circuits. The readout signal output is obtained by scanning sequentially the outputs of the integrating circuits.
