ABSTRACT:
A scanning type readout device having a photoelectric conducting layer and electrode segments arranged one-dimensionally on one surface of the photoelectric conducting layer. The electrode segments are electrically insulated from each other and each has a size equal to one image element and opposite electrodes are arranged on the other side surface of the photoelectric conducting layer so that each of the opposite electrodes is in opposition to a plurality of the electrode segments. First semiconductor switches are connected respectively to the opposite electrodes and second semiconductor switches connected respectively to some of said electrode segments. A common load resistor and a power source are connected between the first and second semiconductor switches, and a scan-controller is used for opening and closing the first and second semiconductor switches in a predetermined sequence thereby to apply a voltage sequentially between the electrode segments and the opposite electrodes so that the electrode segments are scanned one-dimentionally. Either of the electrode segments or the opposite electrodes are made transparent and a light image is projected on the photoelectric conducting layer from the side of the transparent electrodes.
