Patent ID: 7265372

Claim:
An image recording medium comprising: a first electrode layer which transmits an electromagnetic wave for recording, a recording photoconductive layer which takes on conductivity by receiving irradiation of the electromagnetic wave for recording, an electric accumulator which accumulates electric charges for a latent image generated on the recording photoconductive layer, a retrieving photoconductive layer which takes on conductivity by receiving irradiation of an electromagnetic wave for retrieval, and a second electrode layer to which the electromagnetic wave for retrieval is irradiated, the second electrode layer comprising a first stripe electrode including a plurality of first line electrodes for generation of photoelectric charge pairs with respect to irradiation of the electromagnetic wave for retrieval and a second stripe electrode including a plurality of second line electrodes for non-generation of the photoelectric charge pairs with respect to the electromagnetic wave for retrieval, the first stripe electrode and the second stripe electrode being alternately arranged approximately in parallel, and the image recording medium being formed by stacking the foregoing constituents in accordance with the above order of enumeration, wherein: the first line electrodes each include an open end and a connected end, and the first stripe electrode further includes a first connection line which connects the connected ends of the first line electrodes; the second line electrodes each include an first end and a second end, and the second electrode further includes a second connection line which connects the first ends of the second line electrodes and connects the second ends of the second line electrodes; and an insulating layer is provided between the first stripe electrode and the second stripe electrode for insulating the first stripe electrode and the second stripe electrode, the insulating layer covering at least an upper surface of the first line electrodes or an upper surface of the second line electrodes, only at a first end region including the open ends of the first line electrodes and a portion of the second line electrodes adjacent to the open ends of the first line electrodes, and a second end region including an intersection of the connection line of one of the first and second stripe electrodes and the line electrodes of the other one of the first and second stripe electrodes.
