Patent number: 8594523Abstract: 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.Type: GrantFiled: November 9, 2009Date of Patent: November 26, 2013Assignee: Brother Kogyo Kabushiki KaishaInventors: Fumitake Tajiri, Terumasa Ito, Masaki Yasuda

Patent number: 8417177Abstract: 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.Type: GrantFiled: December 9, 2008Date of Patent: April 9, 2013Assignee: Brother Kogyo Kabushiki KaishaInventors: Sakae Ito, Shusaku Tsusaka, Yasuo Tamaru, Tomitake Aratachi, Terumasa Ito

Patent number: 7725053Abstract: 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.Type: GrantFiled: July 12, 2005Date of Patent: May 25, 2010Assignee: Brother Kogyo Kabushiki KaishaInventors: Tomitake Aratachi, Terumasa Ito

Patent number: 7555239Abstract: 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.Type: GrantFiled: September 17, 2008Date of Patent: June 30, 2009Assignee: Brother Kogyo Kabushiki KaishaInventors: Terumasa Ito, Tomitake Aratachi, Takahiro Ikeno, Masatoshi Shiraki
