Patent number: 11198578Abstract: A sheet feeding device includes a stacking portion, a feeding portion, a contact and separation mechanism, a separation conveying portion, a detecting portion, a size acquiring portion, and a controller. In a first mode, in a case that the detecting portion detects passing of a trailing end of the current sheet after the separating operation, the controller causes the contact and separation mechanism to start a contact operation in which the feeding portion is contacted to a sheet stacked on the stacking portion in order to feed a subsequent sheet. In a second mode, before the detecting portion detects passing of a trailing end of the current sheet after the separating operation, the controller causes the contact and separation mechanism to start, on the basis of a distance in which the current sheet is fed by the separation conveying portion, the contact operation to feed the subsequent sheet.Type: GrantFiled: July 2, 2020Date of Patent: December 14, 2021Assignee: Canon Kabushiki KaishaInventor: Takayuki Suga
