  • Patent number: 11233950
    Abstract: An electronic device includes an open-close detector configured to detect an open-close state indicating whether an optical path open-close device of a film camera is open or closed, a displacement detector configured to detect a displacement of a movable portion of the film camera interlocked with a movement of an operation portion of the film camera, and control circuitry. In response to a detection result of the displacement detector, the control circuitry selects a measurement mode for measuring an open time during which the optical path open-close device is open, from a plurality of operation modes of the electronic device. In the measurement mode, the control circuitry measures the open time based on the open-close state detected by the open-close detector.

  • Patent number: 8614840
    Abstract: An image reading apparatus includes an image reading member disposed in one of two regions that face each other with a transport path of a document therebetween, the image reading member being used for reading an image on the document, the image reading member including a light-receiving portion, a light-collecting member that collects reflected light reflected from the document onto the light-receiving portion, and a protruding portion that protrudes toward the transport path; and an opposing member disposed in the other of the two regions, the opposing member having a recess formed therein, the recess allowing the protruding portion of the image reading member to enter thereinto, the opposing member being disposed opposite the image reading member with the transport path therebetween.

  • Patent number: 8498026
    Abstract: An image reader includes a cabinet and an optical system. The cabinet has four plate members fixed to each other by laser welding from a side direction of the image reader and has a bottom wall fixed to the four plate members by laser welding from a side direction or a lower direction of the image reader. The cabinet has a first opening for a document read window opening toward an upper direction of the image reader. Each of the plate members is bended in letter L shape to form an upper end part and a side wall. The optical system is housed in the cabinet for reading an image of a document through the opening.

  • Patent number: 7518763
    Abstract: A scanner is provided with an illumination lamp for emitting light to a first side of a document from one side of a transfer path and a CCD image sensor for receiving light reflected from the first side of the document, and a CIS provided in a document feeder is provided with an LED for emitting light to a second side of the document from the other side of the transfer path and a line sensor for receiving light reflected from the second side of the document. The illumination lamp is a xenon lamp, and the LED is a white LED having emission characteristics different from those of the xenon lamp. To the CIS, a filter is attached, which brings emission characteristics of light emitted from the LED onto a document closer to those of light emitted from the illumination lamp onto the document.
