Publication number: 20240094671Abstract: An image forming apparatus includes a fixing device to heat a recording material at a use position, an opening and closing member, and a drawer unit. In a state where the fixing device is at the use position, part of the fixing device is located in a space for the drawer unit to pass through when moved from a first inner position to a first outer position so that movement of the drawer unit from the first inner to the first outer position is restricted. The fixing device is retracted from the use position to a retracted position so that the movement of the drawer unit from the first inner to the first outer position is allowed. Part of the fixing device at the retracted position is at a position higher than a position of an upper cover portion of the opening and closing member at a closed position.Type: ApplicationFiled: September 11, 2023Publication date: March 21, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085825Abstract: An image forming apparatus to form an image on a recording material includes an apparatus main body having a first end provided with an opening and having a second end, a fixing device to heat the recording material, an opening and closing member, a drawer unit having a first photosensitive drum, and a transfer device. When being moved from a first inner position inside the apparatus main body to a first outer position outside the apparatus main body through the main body opening, the drawer unit is to be moved in a moving direction intersecting with a rotation axis of the first photosensitive drum, and is to be moved away from the second end. When being moved from a second inner position inside the apparatus main body to a second outer position outside the apparatus main body, the transfer device is moved away from the second end.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085824Abstract: An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device a including a belt. When image formation on a recording material is performed, the drawer unit is at a first apparatus main body inner position and the transfer device is at a second apparatus main body inner position. In this drawer unit state, (a) a part of the transfer device is disposed downstream of the drawer unit in a moving direction in which the drawer unit moves from the first inner position to a first apparatus main body outer position, and (b) in a vertical direction, an area where the part of the transfer device is positioned overlaps, at least in part, with an area where the drawer unit is positioned. The transfer device includes a cleaning member to clean the belt and is accommodated in the part of the transfer device.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085849Abstract: An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device including a belt. The drawer unit includes a first cartridge, a support member to which the first cartridge is detachably attached, and a first photosensitive drum disposed on the support member or the first cartridge. The drawer unit is moved to a first inner position inside the apparatus main body and to a first outer position outside the apparatus main body. The transfer device is moved to a second inner position inside the apparatus main body and to a second outer position outside the apparatus main body. The belt contacts the first photosensitive drum with the transfer device at the second inner position. The transfer device is moved from the second inner to the second outer position when the drawer unit is moved from the first inner to the first outer position.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20100085722Abstract: A suction surface member is provided on an electronic component module including an electronic component base plate and surface mount device mounted on the electronic component base plate in order to provide a suction surface at a location that is substantially at the same level as or higher than that of an upper end of a transistor that is the tallest surface mount device. The suction head adheres to the suction surface to hold the electronic component module and the electronic component module is mounted on a motherboard defining the target board. Then a treatment is performed to prevent a situation in which an upper end of the suction surface member is higher than the upper end of the tallest surface mount device mounted on the electronic component base plate.Type: ApplicationFiled: December 7, 2009Publication date: April 8, 2010Applicant: MURATA MANUFACTURING CO., LTD.Inventors: Kunihiro KOYAMA, Muneyoshi YAMAMOTO, Takanori UEJIMA, Dai NAKAGAWA, Masaki KIMURA

Patent number: 7653360Abstract: A high-frequency composite component for selectively switching a GSM-system signal path and a DCS-system signal path for a signal transmitted to or received from an antenna terminal by a diplexer. Transmission-side input terminals and reception-side balanced output terminals to be switched by high-frequency switches are included in the GSM and the DCS systems. Matching elements include inductors and capacitors that are inserted between the reception-side balanced output terminals and the output side of surface acoustic wave filters.Type: GrantFiled: April 10, 2008Date of Patent: January 26, 2010Assignee: Murata Manufacturing Co., Ltd.Inventors: Takanori Uejima, Naoki Nakayama, Tetsuro Harada, Kunihiro Koyama
