Patent number: 9753427Abstract: An opening/closing detection mechanism has a multifunctional peripheral body portion, a front cover, a side cover, and an interlock mechanism. The interlock mechanism contains a switch, a plate-like portion, a bulged portion, and a rocking mechanism. The bulged portion is provided on the side cover. When the side cover is in the closed state, the bulged portion abuts on a rear region located on the side opposite to the front cover with respect to a region where a projection portion is provided of the switch. The rocking mechanism rocks the switch in the opening/closing direction of the front cover according to the opened/closed state of the side cover.Type: GrantFiled: April 5, 2016Date of Patent: September 5, 2017Assignee: KYOCERA DOCUMENT SOLUTIONS INC.Inventors: Hiroyuki Maeda, Yoshiaki Tashiro

Patent number: 9606490Abstract: A rotation force transmission mechanism (30) includes a torque limiter (50), a breaking member (60) and a clutch member (55). The torque limiter (50) is configured to couple the first rotating member (35) and the driving source (40) to each other so as to able to transmit the rotation force until a torque of a predetermined value is applied, and to decouple from each other if a torque larger than the predetermined value is applied. The braking member (60) is configured to apply a torque exceeding the predetermined value to the first rotating member (35). The clutch member (55) is capable of being switched into a transmission state in which the rotation force can be transmitted to the first rotating member (35) and an interruption state in which the transmission of the rotation force is interrupted, in the second rotation force transmission path (P2).Type: GrantFiled: January 26, 2016Date of Patent: March 28, 2017Assignee: KYOCERA Document Solutions Inc.Inventor: Yoshiaki Tashiro

Patent number: 9546060Abstract: A sheet conveying device includes a driving roller, a driven roller and a pair of bearing members. The pair of bearing members is configured to rotatably support both ends of a rotating shaft of the driven roller. The bearing member has a supporting part and a pressing part. The supporting part is formed by winding an end portion on one side of a wire rod in a spiral shape. The supporting part has a shaft hole through which one end of the rotating shaft can be inserted. The pressing part is formed by winding an end portion on the other side of the wire rod in a spiral shape in an orthogonal direction to the rotating shaft. The pressing part is disposed so as to press the supporting part in a direction in which the driven roller comes into pressure contact with the outer face of the driving roller.Type: GrantFiled: October 5, 2015Date of Patent: January 17, 2017Assignee: KYOCERA Document Solutions Inc.Inventor: Yoshiaki Tashiro

Patent number: 9022382Abstract: A sheet feed device includes a feed unit and a sheet loading cassette. The feed unit includes a separation conveyance portion that is composed of a feed member and a separation member, a separation holder that supports the separation member and is swingable, and a pressing member that presses the separation holder. The sheet loading cassette includes a grip portion, a pressure release member that, in conjunction with an operation of drawing out the sheet loading cassette, comes into contact with the pressing member, an operation lever that is provided at the grip portion. In a state where the sheet loading cassette is inserted in the apparatus main body, the operation lever is gripped together with the grip portion, and thus the pressure release member slides to come into contact with the pressing member, so that the pressing member is released from the separation holder.Type: GrantFiled: July 17, 2014Date of Patent: May 5, 2015Assignee: KYOCERA Document Solutions Inc.Inventors: Hiroaki Takai, Yoshiaki Tashiro, Toshio Hori, Yoshio Sugishima, Hideaki Doyo, Noriko Masuta

Patent number: 8215635Abstract: A sheet feeder has a tray on which a sheet to be fed is to be placed. A lift plate is at a feeding end of the tray and has a first end at an upstream side in a feeding direction connected rotatably to the tray. The lift plate is displaceable between a feeding posture where a second end at a downstream side in the feeding direction is lifted up and a retracted posture where the second end is lower than in the feeding posture due to its own weight. A biasing member gives a biasing force to an elevating member in a direction to lift the lift plate to the feeding posture. A lowering mechanism gives a pressing force against the force of the biasing member to lower the lift plate to the retracted posture.Type: GrantFiled: March 11, 2011Date of Patent: July 10, 2012Assignee: Kyocera Mita CorporationInventors: Hiroshi Wada, Toshio Hori, Yoshiaki Tashiro, Hironori Daigo, Seiji Okada, Yuichiro Tanaka, Nobuhiro Nishioka
