Patent number: 8860958Abstract: A sheet conveyer device, including a roller to convey a sheet by rotating in a normal direction and a holder rotatably arranged on a roller shaft, is provided. The holder includes a roller gear system arranged on the roller shaft and having a roller driving gear to drive the roller, a shutter rotatably arranged on a shutter shaft to restrict access of the sheet to the roller, a shutter gear system to connect a path between the roller gear system and the shutter, a one-way clutch to disconnect the path between the roller gear system and the shutter when the roller rotates in the normal direction, and a torque limiter to allow the roller to rotate in a reverse direction. The holder rotates about the roller shaft in the same reverse direction as the roller when the roller rotates in the reverse direction.Type: GrantFiled: March 29, 2012Date of Patent: October 14, 2014Assignee: Brother Kogyo Kabushiki KaishaInventors: Tetsuo Ito, Kazutoshi Kuse, Masanori Hamaguchi

Patent number: 8564857Abstract: In an image reading apparatus, cables may be used to connect reading units (e.g., scanning devices) to a controller or control circuit board configured to execute certain instructions and perform various functions. The cables may be routed between the reading units and the controller so as to reduce and/or eliminate noise. For example, the cables may be routed through contact prevention devices that may include ferrite cores. The cables may also be routed in a manner so as to maintain a predefined distance therebetween and to minimize interference. For example, the cables may extend downward from a corresponding reading portion, change course to a horizontal direction parallel to the rotation axis of an openable unit of the image reading apparatus and such that the cable extends toward the controller, and subsequently extend downward such that the flexible flat cable is insertable into a corresponding connector of the controller.Type: GrantFiled: March 23, 2011Date of Patent: October 22, 2013Assignee: Brother Kogyo Kabushiki KaishaInventors: Kotaro Kurokawa, Sakae Ito, Kazutoshi Kuse

Patent number: 7635127Abstract: A sheet feeding apparatus for separating and feeding stacked sheets one by one, includes a separation roller which rotates and applies a feeding force to a sheet of stacked sheets, a friction member which opposes the separation roller and which applies friction against the feeding force, and a rotation speed controller which controls a rotation speed of the separation roller. The rotation speed of the separation roller varies between a first speed and a second speed. The separation roller rotates at the first speed when separating a first one of the stacked sheets. The separation roller rotates at the second speed when separating sheets after separating a predetermined number of the stacked sheets. The first speed is slower than the second speed.Type: GrantFiled: June 26, 2007Date of Patent: December 22, 2009Assignee: Brother Kogyo Kabushiki KaishaInventor: Kazutoshi Kuse

Publication number: 20030184771Abstract: An inkjet printer in a multi-function device includes a scanner that reads an image of a document, a sheet transport path along which a recording sheet is transported, a print unit having a printhead that ejects ink onto the recording sheet, a discharge portion from which the recording sheet is discharged, and ink cartridges that store ink to be supplied to the printhead. The sheet transport path and the discharge portion are disposed under the scanner, and the ink cartridges are disposed under the discharge portion. Main components of the inkjet printer, such as the ink cartridges, a main board for controlling operation of the printer, and a waste ink absorber, are arranged so that they do not overlap one another in the plan view of the ink-jet printer. With this structure, the ink-jet printer as well as the multi-function device are made thin and compact.Type: ApplicationFiled: March 27, 2003Publication date: October 2, 2003Applicant: Brother Kogyo Kabushiki KaishaInventors: Hideki Yamamoto, Kazutoshi Kuse, Mutsuo Fukuoka, Masahiko Sasa
