  • Patent number: 8517922
    Abstract: A socket section 72 for providing a first light guide 13 is supported movably in an endoscope main body 4, and a plug section 62 for fixing a second light guide 15 is disposed in an endoscope insertion section 5. The socket section 72 is configured to move freely in an insertion direction of the endoscope insertion section 5 and to a direction orthogonal with respect to the insertion direction. Furthermore, an attachment-detachment-detecting switch 33 is disposed in the endoscope main body 4 so as to detect that the endoscope insertion section 5 has been separated from the endoscope main body 4 before the plug section 62 is freely detached from the socket section 72. By this configuration, it is possible to attach the endoscope insertion section from the endoscope main body and detach them easily and reliably, in particular, to reduce loss of light caused by the attachment and the detachment.

  • Publication number: 20120197082
    Abstract: A rotary self-propelled endoscope system includes an insertion section body, an insertion section, a drive unit, a torque detection unit, and a control unit. In a distal end portion of the insertion section body, a rigid distal end portion including an image pickup apparatus is disposed. The insertion section is rotatably fit to the outside of the insertion section body, and includes a rotary tubular member having a helical portion formed by a helical concave-convex portion. The drive unit applies the rotary tubular member with axial and rotational drive force. The torque detection unit detects torque information of the rotary tubular member. On the basis of the torque information detected by the torque detection unit, the control unit compares a present value with a preset limit value for controlling the torque of the rotary tubular member, and controls the drive unit on the basis of the comparison result.

  • Publication number: 20120147395
    Abstract: A sheet interval, serving as the distance between conveyed recording materials, is properly controlled based on a kind of a recording material and any one of a printing ratio, an adhesion amount of toner, and the presence or absence of graphic data, thus allowing printing at throughput suitable for, for example, the kind of the recording material and the printing ratio without changing an image forming condition such that image quality does not vary.

  • Publication number: 20110299868
    Abstract: An object is to perform control so that power supplied in positive half-waves and power supplied in negative half-waves are symmetric in a control period even if a safety circuit based on a hardware circuit is activated. A CPU 202a controls to supply power of six half-waves from a third half-wave to an eighth half-wave (sections of E to K of a power supply waveform) after a limitation in the supply of the power by the safety circuit is released if the safety circuit limits the supply of the power from an AC power supply 401 to a heater 301 in a third half-wave (section of C to D in the power supply waveform) in the control period.

  • Patent number: 7957687
    Abstract: Preventing a paper jam as much as possible when actual paper size differs from designated paper size with increasing throughput by starting conveyance of a second sheet before detecting the length of a first sheet. Unless a register sensor has detected the rear edge (step S303), start of feeding the next sheet is checked (step S304). If started, a prescribed value 1 is applied (step S305). If not started, a prescribed value 2 is applied (step S306). Unless the rear edge is detected before a timer measures “estimated time+prescribed value” (step S307), a paper jam decision is made (step S308). If the rear edge is detected before the timer measures the “estimated time+prescribed value” (step S303), the processing is completed without making a paper jam decision. Making the prescribed value 1 less than the prescribed value 2 enables reducing the paper jam caused by incorrect setting.
