  • Patent number: 8594523
    Abstract: In an image forming apparatus, a temperature of a heating member heated by a heat source to fix a developer image on a recording sheet is detected by a temperature sensor disposed apart from the heating member. A controller controls the heat source based upon a temperature determined mathematically by application of a specific function to the temperature detected by the temperature sensor. In the controller, the specific function is switched among a plurality of functions according to a control mode which is switchable among a plurality of modes and in which operation of the heat source is regulated.

  • Patent number: 8417177
    Abstract: In a printer, a scanner unit is formed into a taper shape having a thinner thickness on a side of a pick-up roller in a removing direction of a process unit, to allow the process unit to be removed from the printer. A part of a sheet feeding path is formed in an area between the process unit and a sheet cassette. An image forming position on the sheet feed path is set lower than an upper end of the pick-up roller. Thus, removal of the process unit can be readily performed. Further, the height of the printer at a position of the pick-up roller can be reduced as compared with a case where the scanner unit is not formed into a taper shape.

  • Publication number: 20100182663
    Abstract: There is provided a light illuminating apparatus including: a light source allowing light to illuminate a hologram-recording medium having a recording layer, where information is recorded by an interference fringe of a signal light and a reference light, and a cover layer on an upper-layer side thereof; a spatial light-modulator performing spatial light-modulation on the light from the light source to generate the signal light and/or the reference light; and a light illuminating unit allowing the light, which is subject to the spatial light-modulation by the spatial light-modulator, as a recording/reproduced light to illuminate the hologram-recording medium through an objective lens, wherein a focus position of the recording/reproduced light is set so that a distance from a surface of the hologram-recording medium to the focus position of the recording/reproduced light is smaller than a distance from the surface to a lower-layer side surface of the recording layer.

  • Patent number: 7725053
    Abstract: A fixing unit of an image-forming device having a heating roller, a pressure roller disposed in confrontation with the heating roller, and a case that rotatably supports the heating roller on both longitudinal ends thereof and covers the heating roller from the side opposite the pressure roller, while leaving the pressure roller exposed. A pair of pressure roller support plates, one end of which is supported on the case, rotatably supports both ends of the pressure roller. With this construction, a more compact fixing unit can be achieved than when the case is configured to cover the heating roller and pressure roller entirely. The fixing unit includes a temperature fuse for restraining abnormal temperature rises in the heating roller, and a temperature fuse cover that extends from an inner wall of the case to provide insulation between the temperature fuse and the heating roller.

  • Publication number: 20100123944
    Abstract: A reproduction apparatus includes: a wavelength-tunable light source that outputs light illuminating a hologram recording medium such that a wavelength is variable; an optical system that illuminates through an objective lens the hologram recording medium with the reference light generated on the basis of light emitted from the wavelength-tunable light source and that includes a power changing section which changes a zoom power of the reference light incident on the objective lens; a temperature detecting section that detects a temperature of the hologram recording medium; and a control section that, when setting the zoom power of the reference light and the wavelength of the wavelength-tunable light source in response to a result of the temperature detected by the temperature detecting section, performs control such that the zoom power of the reference light and the wavelength of the wavelength-tunable light source satisfy a condition [ ? ? ? m = ? ? ? ? ? W ] .

  • Patent number: 7555239
    Abstract: A fixing unit is disposed at a position closer to a rear side wall than to a front side wall of a casing. A top wall is formed with a depressed portion depressed toward inside the casing. The depressed portion serves as a sheet discharge tray for receiving a recording medium that has passed through the fixing unit. The sheet discharge tray includes a tray member detachably disposed at the top wall. The rear side wall is formed with an opening through which the fixing unit is removed. When the tray member is disposed at the top wall, the tray member is positioned above and adjacent to the fixing unit and overlaps the fixing unit when viewed through the opening, thereby preventing the fixing unit from being removed from the casing. The fixing unit is removable through the opening when the tray member is detached from the top wall.
