Patent number: 8200118Abstract: An image-forming device includes: a casing; an image-forming section including a plurality of image-forming units; a paper supply unit; and a discharge unit. The plurality of image-forming units are arranged substantially vertically within the casing when the casing is disposed in an orientation in which it is intended to be used, each image-forming unit forming an image in a corresponding color. The paper supply unit is disposed above the image-forming units when the casing is disposed in the orientation in which it is intended to be used. The paper supply unit is configured to accommodate a recording medium substantially in a vertical orientation and to supply the recording medium to the image-forming section. The discharge unit is disposed above the image-forming units when the casing is disposed in the orientation in which it is intended to be used. The discharge unit is configured to receive the recording medium discharged from the image-forming section substantially in a vertical orientation.Type: GrantFiled: November 18, 2009Date of Patent: June 12, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Shougo Sato, Yasushi Okabe, Shigeharu Katayama, Yasutake Yamaguchi

Patent number: 7689158Abstract: An image forming apparatus includes an apparatus main body and an original reading device disposed on top of the apparatus main body. A sheet supply cassette, a sheet discharge tray, an original feed tray, and the original discharge tray are oriented such that their lengthwise directions are aligned with the first horizontal direction, and are arranged to overlap with one another in the vertical direction. A pair of side walls is disposed at both widthwise ends of the sheet supply cassette, the sheet discharge tray, the original feed tray, and the original discharge tray. The both widthwise ends of these components are formed as edge portions. The pair of side walls covers an entire length of each of the edge portions, thereby supporting all of the sheet supply cassette, the sheet discharge tray, the original feed tray, and the original discharge tray.Type: GrantFiled: November 1, 2006Date of Patent: March 30, 2010Assignee: Brother Kogyo Kabushiki KaishaInventors: Shougo Sato, Naoya Kamimura, Shigeharu Katayama, Hidenori Hisada

Patent number: 7489888Abstract: An image-forming device has a main casing, a cartridge, and a guiding unit. The main casing has a cartridge access opening and a cartridge loading section in communication with the cartridge access opening. The cartridge access opening has an opening plane. The cartridge is detachably counted in the cartridge loading section through the cartridge access opening. The guiding unit provides a loading path to load/unload the cartridge with respect to the cartridge loading section. The guide unit is configured to orient the loading path toward a direction substantially parallel to the opening plane outside of the main casing, thereby curving a track of the cartridge.Type: GrantFiled: March 24, 2006Date of Patent: February 10, 2009Assignee: Brother Kogyo Kabushiki KaishaInventors: Shougo Sato, Yasushi Okabe, Shigeharu Katayama, Yasutake Yamaguchi
