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: 20200299095Abstract: A sheet transport device includes a transport unit, a load section, and a sheet accommodation section. The transport unit has a transport path along which a sheet read at a read position is transported to an output unit. The sheet output by the output unit is loaded onto the load section. The sheet accommodation section is disposed downstream in an output direction of the sheet from an inner wall surface extending upward adjacent to the load section and has a recess capable of accommodating a sheet of a predetermined minimum size. A retrieval space through which the sheet accommodated in the sheet accommodation section is retrievable is provided by exposing the transport path in a direction opposite to a loading direction of the sheet.Type: ApplicationFiled: August 15, 2019Publication date: September 24, 2020Applicant: FUJI XEROX CO., LTD.Inventors: Yosuke TAKAHASHI, Masato SERIKAWA, Takakiyo TOBA, Yuta ABE, Isamu ADACHI

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
