ABSTRACT:
An image reader device comprises photo sensing element arrays each of a plural number of blocks each consisting of a plural bits of photo sensing elements, a plural number of first switching elements, connected to the photo sensing elements, for transferring en bloc the charge of all bits generated in the photo sensing element array, a plural number of second switching elements, connected to the photo sensing elements, for resetting en bloc the charge of all bits left in the photo sensing elements after the charge transfer, a plural number of capacitor portions, connected to the first switching elements, for retaining the transferred charge, a plural number of third switching elements, connected to the first switching elements, for transferring the charge stored in the capacitor portions, a plural number of wiring capacitor portions, formed connecting to the third switching elements, for retaining the charge transferred by the third switching elements, common signal lines for connecting the third switching elements every corresponding bits in the blocks, and drive ICs for receiving the charge through the common signal lines and outputting it in the form of image signals.
