Patent number: 11425274Abstract: A sheet transport device includes a sheet transport unit, a detector, and a releasing unit. The sheet transport unit transports a sheet by nipping the sheet in a nip between multiple pairs of transport rollers arranged in a sheet width direction intersecting a sheet transport direction. The detector detects a size of the transported sheet. The releasing unit releases the nip of one or more of the pairs of transport rollers outside a transport region of the sheet based on the size of the sheet detected by the detector.Type: GrantFiled: August 15, 2019Date of Patent: August 23, 2022Assignee: FUJIFILM Business Innovation Corp.Inventors: Isamu Adachi, Takakiyo Toba, Yosuke Takahashi, Masato Serikawa, Yuta Abe

Publication number: 20200299087Abstract: A sheet transport device includes a sheet load tray on which a sheet is loaded, a side-edge positioning unit, and a regulating unit. The side-edge positioning unit comes into contact with a side edge of the sheet in a direction intersecting a sheet transport direction at an upper surface of the sheet load tray and positions the side edge of the sheet to a normal position. The regulating unit is provided in a rotatable manner about a rotation shaft at a lower surface of the sheet load tray and regulates an output position of the sheet by rotating a stopper of the regulating unit to a position where the stopper is capable of colliding with a downstream edge of the sheet to be output in an output direction when the side-edge positioning unit moves to a position corresponding to a minimum width of the sheet.Type: ApplicationFiled: August 14, 2019Publication date: September 24, 2020Applicant: FUJI XEROX CO., LTD.Inventors: Masato SERIKAWA, Takakiyo TOBA, Yosuke TAKAHASHI, Isamu ADACHI, Yuta ABE
