  • Patent number: 10204325
    Abstract: Disclosed herein are an object detection apparatus for detecting an object and a financial apparatus using the same. In an embodiment, the object detection apparatus may include a light emission unit configured to emit light and a light-reception unit configured to receive both direct light that is emitted by the light emission unit and reflected light of the light emitted by the light emission unit which is reflected by an object to be detected. In accordance with an embodiment of the present invention, the object detection apparatus can perform self-diagnosis, such as autonomously determining whether a failure is present and measuring sensitivity, although an object, that is, the subject of detection, is not present and process media, such as bills. Accordingly, performance in detecting a medium can be improved in financial apparatuses that perform deposit and withdrawal.

  • Patent number: 7227151
    Abstract: In a photoelectric conversion device, in order to suppress alteration of its properties during a long time use, lower the decrease of the S/N ratio due to a dark current output, and shorten image-pickup cycles, MIS type photoelectric conversion elements using an amorphous semiconductor material are connected with an electric power source for applying bias for photoelectric conversion, an electric power for resetting an accumulated electric charge, and a setting point for applying zero bias at the time of non-operation of the element through a switch. Emitted x-rays from an x-ray source, which is a first light source, come into collision against phosphor after being transmitted through an object body to be inspected and then are absorbed in the phosphor to be converted into visible light rays. The visible light rays from the phosphor are radiated to the photoelectric conversion elements. Prior to reading out of the x-ray image, an LED light source is lighted.
