Patent number: 10467511Abstract: A recording apparatus includes a feeding roller, a rear feeding unit being provided on a rear side of the apparatus, and a medium reversing unit provided below a medium support section and including a reversing roller. At least a part of a rear side of the rear feeding unit forms a medium transport path in which the medium is transported by the reversing roller, the rear feeding unit includes a driven roller configured to nip the medium with the reversing roller therebetween, and at least a part of the driven roller is located in a roller accommodating space formed on a rear side of the medium support section.Type: GrantFiled: February 22, 2018Date of Patent: November 5, 2019Assignee: Seiko Epson CorporationInventors: Haruki Miyasaka, Narihiro Oki, Shinji Kanemaru

Patent number: 10457510Abstract: A recording apparatus includes a return member switchable between a first orientation in which a portion of the return member overlaps a feed roller in a side view of a medium feeding path and a second orientation in which the return member is turned toward a downstream side in a medium feeding direction and does not overlap the feed roller. The return member changes an orientation thereof from the second orientation to the first orientation, thereby returning a medium to an upstream side in the medium feeding direction. When a transport roller disposed downstream of the feed roller is driven in reverse to return the medium to the upstream side and position the medium at a recording start position, the return member takes a third orientation in which the return member is raised toward the upstream side further than in the first orientation.Type: GrantFiled: May 24, 2018Date of Patent: October 29, 2019Assignee: Seiko Epson CorporationInventors: Shinji Kanemaru, Kazuhisa Nakamura, Tatsuya Shirane

Patent number: 10392207Abstract: A medium feed apparatus includes a first support face and a second support face. The first support face supports a medium fed by a feed unit that feeds medium by supporting such that the medium adopts an inclined orientation. The second support section is positioned upstream of the first support face in a feed direction, and supports the medium together with the first support face. The second support face is at a position set back from the first support face, and an angle of inclination from a lower end portion to an upper end portion of the second support face is steeper than an angle of inclination of the first support face.Type: GrantFiled: March 15, 2018Date of Patent: August 27, 2019Assignee: Seiko Epson CorporationInventor: Shinji Kanemaru

Patent number: 10222734Abstract: A moving-side roller reliably separates from a stationary-side roller so as to enable appropriate document transport. An image reading apparatus causes a roller support member supporting the moving-side roller to come into contact with the stationary-side roller. A contact state and a separation state can be switched. The image reading apparatus includes an external force providing portion to exert a third external force on the roller support member in a direction for restraining warping that is generated in the roller support member by a first external force that a cam exerts on the roller support member and by a second external force that an urging device exerts on the roller support member.Type: GrantFiled: June 23, 2017Date of Patent: March 5, 2019Assignee: Seiko Epson CorporationInventors: Kohei Kozaki, Kensuke Tamai, Shinji Kanemaru, Hitoshi Igarashi
