Patent number: 11945683Abstract: A pair of regulating guides is disposed on both sides of a conveying belt in a sheet width direction Y, each having a support surface that supports an end edge in the width direction of the sheet conveyed while being nipped by the conveying belt and balls and a guide surface that faces the end edge of the sheet in the width direction. Each of the pair of regulating guides is movable to a first guide position at which the end edge of the sheet in the width direction is supported by the support surface and guided by the guide surface and to a second guide position at which the end edge of the sheet in the sheet width direction is supported by the support surface and which is retracting further away from the end edge in the sheet width direction than the guide position.Type: GrantFiled: August 25, 2021Date of Patent: April 2, 2024Assignee: CANON FINETECH NISCA INC.Inventors: Toshiyuki Iwata, Yuuki Kubota, Tsukasa Kondo, Tetsuya Kawasaki

Patent number: 11891271Abstract: The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. In a sheet conveying apparatus that conveys a sheet using a conveying belt and balls, a sheet may be jammed and stopped on the conveying belt. In this case, it is difficult for a user to take out the sheet through a take-out port if the sheet is nipped by conveying roller pairs disposed upstream and downstream relative to the conveying belt in a sheet conveying direction. Thus, conveying roller pairs and the conveying belt are operated such that the sheet, which is stopped on the conveying belt and hence should be taken out through the take-out port, is brought into a state of being nipped only by the conveying belt and balls.Type: GrantFiled: August 25, 2021Date of Patent: February 6, 2024Assignee: CANON FINETECH NISCA INC.Inventors: Toshiyuki Iwata, Hiroshi Mochizuki, Tsukasa Kondo, Tetsuya Kawasaki, Yuuki Kubota

Patent number: 11884507Abstract: The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on the side closer to the regulating guide in the sheet width direction Y, through which a sheet stopped on the conveying belt is taken out. A guide moving part moves the regulating guides. When a sheet is stopped on the conveying belt, the guide moving part moves the first and second regulating guides such that the regulating guide is retracted to a position at which a support surface does not support a first sheet end edge.Type: GrantFiled: August 25, 2021Date of Patent: January 30, 2024Assignee: CANON FINETECH NISCA INC.Inventors: Toshiyuki Iwata, Takato Mizuno, Tsukasa Kondo, Tetsuya Kawasaki, Yuuki Kubota

Patent number: 11303141Abstract: A protection circuit for a battery includes a discharge FET, a control circuit, a first small-signal FET, and a second small-signal FET. The discharge FET connected in series to a battery interrupts an electric current. The control circuit switches on or off the discharge FET. The first small-signal FET connected in parallel between a gate (G) and a source (S) of the discharge FET is switched to an ON state, to set a gate voltage of the discharge FET to an OFF-state voltage. The second small-signal FET connected in parallel between G and S of the discharge FET detects a voltage between a drain (D) and S of the discharge FET. When the voltage between D and S of the discharge FET exceeds a preset voltage, the second small-signal FET is switched to an ON state to set the gate voltage of the discharge FET to the OFF-state voltage.Type: GrantFiled: July 12, 2018Date of Patent: April 12, 2022Assignee: SANYO Electric Co., Ltd.Inventors: Tetsuya Kawasaki, Hisashi Kameyama, Naoki Kawai, Takahiro Yamashita
