Patent number: 11604429Abstract: A sheet conveyance apparatus includes a rotary member and an opposing member to convey a sheet in a conveyance nip, and an abutting member abutting a surface of the rotary member, which is supported between a first position and a second position with respect to the abutting member. When the sheet is not passing through the conveyance nip the rotary member is positioned at the first position and abuts the opposing member, and when the sheet is passing through the conveyance nip the rotary member is positioned at the second position which is more separated from the opposing member than the first position. The abutting member abuts the rotary member regardless of which of the first position and the second position the rotary member is positioned at, and the opposing member and the abutting member are supported so they do not move in a radial direction of the rotary member.Type: GrantFiled: June 17, 2019Date of Patent: March 14, 2023Assignee: CANON KABUSHIKI KAISHAInventor: Shoji Kamizato
