Publication number: 20140078528Abstract: A sheet conveying device includes a sheet stacking portion on which sheets are to be stacked, a sheet conveyance path, a sheet feeding member, a driving unit, a stopper and an interlocking unit. The sheet is conveyed from the sheet stacking portion in a predetermined conveying direction in the sheet conveyance path. The sheet feeding member is arranged at an entrance side of the sheet conveyance path and conveys the sheet by being driven and rotated. The stopper is projectable into and retractable from the sheet conveyance path at a side upstream of the sheet feeding member in the conveying direction and prevents the sheets stacked on the sheet stacking portion from coming into contact with the sheet feeding member in a projecting state. The interlocking unit causes the stopper to project into and retract from the sheet conveyance path in accordance with rotational movements of the sheet feeding member.Type: ApplicationFiled: September 12, 2013Publication date: March 20, 2014Applicant: KYOCERA Document Solutions Inc.Inventor: Toshinori Muraoka

Patent number: 8675262Abstract: A position adjustment mechanism (90) includes a rack (91) fixed onto an upper surface of a second hinge member (87), a worm gear 93 that meshes with the rack (91), a handle (95) that rotates the worm gear (93), and a lever (97) that presses the second hinge member (87) against the first hinge member (85) to fix the second hinge member (87) to the first hinge member (85). The lever (97) is operated to release the pressure on the second hinge member (87) so that the handle (95) is operated, to thereby adjust a tilt of the document conveying device (27) with respect to the image reading portion (6) without using a tool and the like. After the adjustment, the lever (97) is operated to press the second hinge member (87), to thereby position the document conveying device (27) precisely at a position after the adjustment.Type: GrantFiled: December 17, 2010Date of Patent: March 18, 2014Assignee: Kyocera Document Solutions Inc.Inventors: Katsuhiko Hanamoto, Takehiko Okada

Patent number: 8675263Abstract: An image reading apparatus to read an image formed on a document sheet is provided. The image reading apparatus includes a sheet conveyer and an image reader, which is controlled by a controller and reads the image formed on the document sheet. The sheet conveyer includes movable parts, which are movably supported by a first supporting member. The image reader is supported by a second supporting member, which is detachably attached to the first supporting member. A cable with a connector connects the controller and the image reader with each other via the connector. The second supporting member is tied to the first supporting member by the cable when the cable connects the controller and the image reader via the connector. The second supporting member is releasable from the first supporting member when the connector is decoupled.Type: GrantFiled: March 28, 2011Date of Patent: March 18, 2014Assignee: Brother Kogyo Kabushiki KaishaInventors: Masaru Takeuchi, Takayuki Akimatsu

Patent number: 8670163Abstract: An image reader includes an original transport device to transport an original, and an image reading device including multiple image sensor arrays having image reading areas staggered relative to the transport direction of the original in such a manner that the multiple image sensor arrays are offset at least partially, in the main scanning direction of the original with a predetermined gap therebetween in the transport direction. There is at least one original transport speed detector to detect the transport speed of the original transported by the original transport device, a storing device to store a reference delay time period which is between when the image sensor arrays on the upstream side read a predetermined position relative to the transport direction and when the image sensor arrays on the downstream side read the predetermined position. Further, there is a misalignment amount calculator, and an image synthesizer to synthesize an image read by the image sensor arrays.Type: GrantFiled: May 25, 2011Date of Patent: March 11, 2014Assignee: Ricoh Company, Ltd.Inventor: Hiroshi Takahashi
