Patent number: 11440757Abstract: In order to downsize an overall apparatus without setting the swing angle of a swing member to be unnecessarily large, a pickup roller, which is for feeding a document disposed on a feeding tray, is supported by a pickup arm that is swingable about a rotation shaft. Depending on the rotational direction of the rotation axis, the pickup arm swings between a first position, in which the pickup roller is in contact with the document on the feeding tray, and a second position, in which the pickup roller is above and not in contact with the feeding tray. An arm member is rotated by rotation of the rotation axis after the pickup arm swings to the second position.Type: GrantFiled: July 24, 2020Date of Patent: September 13, 2022Assignee: Canon Kabushiki KaishaInventors: Yuya Yasuda, Masahiro Kawanishi
