Patent number: 11254537Abstract: Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.Type: GrantFiled: May 23, 2019Date of Patent: February 22, 2022Assignee: Canon Kabushiki KaishaInventors: Yuki Emoto, Kosuke Yamamoto, Norio Sakurai, Toshiaki Somano
