Patent number: 9829847Abstract: A recording medium transporting device includes a transport path, a first open-close portion, and a second open-close portion. A recording medium on which an image is formed is transported over the transport path. The first open-close portion is disposed on a side surface of the transporting device so as to be openable to cover and closeable to uncover the transporting device. The first open-close portion renders a first portion of the transport path open when the first open-close portion is opened so as to uncover the transporting device. The second open-close portion is located inside the transporting device at a position further inward of the first open-close portion so as to be openable to cover and closeable to uncover the transporting device. The second open-close portion renders a second portion of the transport path open when the second open-close portion is opened so as to uncover the transporting device.Type: GrantFiled: February 23, 2016Date of Patent: November 28, 2017Assignee: FUJI XEROX CO., LTD.Inventors: Mizuki Arai, Hiromitsu Tomioka, Kohei Takahashi, Riwako Miyauchi

Patent number: 9242824Abstract: A transport mechanism includes a guide member that guides a transport object, which has a leading end and a trailing end, to be transported. The guide member includes a curved portion that is a curved portion of the guide member. The transport mechanism also includes a transport member that is disposed downstream of the curved portion in a transport direction in which the transport object is transported along the guide member, transports the transport object, and moves the transport object in an intersecting direction that intersects the transport direction. In the transport mechanism, when a length of the transport object in the transport direction is equal to or greater than a predetermined specified length that is greater than a distance between the transport member and the curved portion, the transport member does not move the transport object in the intersecting direction.Type: GrantFiled: May 14, 2014Date of Patent: January 26, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Mizuki Arai, Naohito Otsuki, Kiyoshi Watanabe, Yoichi Yamakawa

Patent number: 9242821Abstract: A transport device includes an abutting member that abuts a leading end of a transport object and transport members that are disposed upstream of the abutting member in a transport direction and transport the transport object to the abutting member. The transport object is a first or second transport object. One of the transport members or the transport members transport the first transport object and cause the leading end of the first transport object to abut the abutting member. When transporting the transport object to a position where the leading end of the transport object abuts the abutting member, a transport force required to transport the second transport object is larger than that required to transport the first transport object. A larger number of transport members are used to transport the second transport object than the number of the transport members used to transport the first transport object.Type: GrantFiled: April 21, 2014Date of Patent: January 26, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Kiyoshi Watanabe, Naohito Otsuki, Yoichi Yamakawa, Mizuki Arai
