Patent ID: 7705282

Claim:
An image detecting device comprising a substrate, the substrate comprising: a plurality of accumulating portions in which, due to the irradiation of incident electromagnetic waves expressing an image which is an object of detection, charges expressing the image are accumulated; a plurality of data lines to which the plurality of accumulating portions are respectively connected individually via switching elements; a plurality of first protection lines for protecting a circuit from excess voltage; a plurality of first diodes whose anodes are connected to a portion of the plurality of first protection lines respectively, and whose cathodes are connected to the plurality of data lines respectively; a plurality of second diodes whose anodes are connected to another portion of the plurality of first protection lines respectively, and whose cathodes are connected to the plurality of data lines respectively; and a detecting circuit connected to the plurality of data lines, the detecting circuit comprising: a plurality of second protection lines for protecting a circuit by discharging, to an exterior, excess charges accumulated at the data lines, a plurality of third diodes whose anodes are connected to a portion of the plurality of second protection lines respectively, and whose cathodes are connected to the plurality of data lines respectively, and a plurality of fourth diodes whose anodes are connected to another portion of the plurality of second protection lines respectively, and whose cathodes are connected to the plurality of data lines respectively, wherein the detecting circuit is adapted to remove charges accumulated respectively in the plurality of accumulating portions, and to detect charge amounts as information of respective pixels structuring the image.
