Patent number: 7742722Abstract: An image forming apparatus is provided with a main body, an image forming assembly accommodated in the main body, a withdrawable unit accommodated in the main body in such a manner as to be withdrawable to the outside, a fixing unit for fixing a toner image to a recording sheet with heat from the heating member by conveying the recording sheet having the toner image transferred thereto while nipping it between a heating member and the pressure member, and a temperature raising device for raising the temperature of the heating member. The fixing unit is detachably mounted on the withdrawable unit. On the other hand, the temperature raising device includes a mounting portion different from that of the heating member, and is fixedly attached to the withdrawable unit and is kept attached to the withdrawable unit even if the fixing unit is separated from the withdrawable unit.Type: GrantFiled: October 24, 2007Date of Patent: June 22, 2010Assignee: Kyocera Mita CorporationInventors: Yuki Shiga, Yukihiro Itoh

Patent number: 7379701Abstract: A sheet cassette (1) according to the present invention has a double structure portion (10) including an upper plate (11) and a lower plate (12). The lower plate (12) has a first guide groove (13) elongated widthwise of a sheet to be contained in the cassette and having a plurality of inch-based size engagement recesses (17) and a plurality of centimeter-based size engagement recesses arranged longitudinally thereof. The upper plate (11) is movable along the lower plate (12) widthwise of the sheet to be contained in the cassette. The inch-based size engagement recesses (17) are effectuated by locating the upper plate (11) at a first position, and the centimeter-based size engagement recesses are effectuated by locating the upper plate (11) at a second position. The sheet cassette (1) further has a width limiting plate slidable widthwise of the sheet to be contained in the cassette according to the width of the sheet.Type: GrantFiled: December 21, 2005Date of Patent: May 27, 2008Assignee: Kyocera Mita CorporationInventors: Satoru Yonemoto, Yukihiro Itoh

Patent number: 6697177Abstract: In an image forming apparatus which uses a hollow space between an image reading section provided in an upper part of the apparatus and an image forming section provided in a lower part of the apparatus as a paper output space, the hollow space is used also as a space for temporarily holding a sheet of paper during a switchback operation. This arrangement helps prevent physical contact between the paper and the body of an operator or other objects and makes it easier to deal with a paper jam which is likely to occur during the switchback operation.Type: GrantFiled: January 19, 1999Date of Patent: February 24, 2004Assignee: Kyocera Mita CorporationInventors: Tetsuro Tomoe, Yukihiro Itoh, Takashi Mihara, Tadahiro Kiyosumi, Susumu Hanano

Patent number: 6496281Abstract: Image forming apparatus including a paper return device for feeding a sheet of paper ejected from a paper output port opening in a main body of the apparatus to its outside back to a paper feeding port also opening in the main body to its outside. For double-sided copying operation, the sheet of paper ejected from the paper output port carrying an image on one side only is returned to the paper feeding port and fed again to an image former from the paper feeding port so that it is not necessary to provide a dedicated paper path for re-feeding the paper. The apparatus includes a paper sensor which senses the paper inserted into the paper feeding port and outputs a paper sensing signal, a discriminator for judging whether the paper return device is in an operating condition, and a paper feed controller which controls a driver for driving a paper feeder such that the paper feeder initiates a paper feed operation when the paper sensing signal is output while the paper return device is in its operating condition.Type: GrantFiled: January 19, 1999Date of Patent: December 17, 2002Assignee: Kyocera Mita CorporationInventors: Shinji Yamamoto, Tetsuro Tomoe, Yukihiro Itoh, Tadahiro Kiyosumi, Eijiro Masaki

Patent number: 6267368Abstract: A paper return device detachably fitted to an image forming apparatus having a paper feeding port for feeding paper from outside the image forming apparatus, a paper transport mechanism for transporting the paper from the paper feeding port to an image forming unit and a paper output port from which the paper carrying an image formed by the image forming unit is ejected to the outside of the image forming apparatus. The paper return device includes a paper return guideway which connects the paper output port of the image forming apparatus to its paper feeding port when the paper return device is fitted to the image forming apparatus, whereby the paper ejected from the paper output port is fed back to the paper feeding port through the paper return guideway.Type: GrantFiled: January 19, 1999Date of Patent: July 31, 2001Assignee: Kyocera Mita CorporationInventors: Tetsuro Tomoe, Kenji Oda, Shinji Yamamoto, Eijiro Masaki, Susumu Hanano, Yukihiro Itoh, Takashi Mihara

Patent number: 5839025Abstract: An image forming apparatus has a paper discharging section provided in its main body. The paper discharging section opens toward the front of the main body. An opening serving as a window for introducing light into the paper discharging section is provided on a side surface of the main body. Light enters the paper discharging section through the opening, so that the paper discharging section is brightened. As a result, it is possible to easily visually confirm whether or not a paper sheet exists in the paper discharging section. Additionally, vent holes adjacent the window opening serve to introduce cooling air along the axis of a fusing roller.Type: GrantFiled: May 22, 1997Date of Patent: November 17, 1998Assignee: Mita Industrial Co., Ltd.Inventors: Yoshifumi Okauchi, Tetsuro Tomoe, Yukihiro Itoh, Masahiko Miyazaki, Syouji Hirano
