Abstract:
A sheet discharging device has a discharge roller pair and a sheet discharge tray arranged selectively either in a first position where the sheet discharge tray is stowed along a side surface of an apparatus main body or in a second position where the sheet discharge tray, swung downward from the first position, protrudes beyond the side surface. The sheet discharge tray has a hook member holding, with one of rotation shafts of the discharge roller pair acting as an engagement shaft, the sheet discharge tray in the first position by engaging with the engagement shaft. As a result of the discharge roller pair being rotated with the sheet discharge tray located in the first position, an engagement releasing member fixed to the engagement shaft releases the engagement of the hook member with the engagement shaft, and the sheet discharge tray moves to the second position.

Claim (Index 1):
A sheet discharging device comprising:\n a discharge roller pair composed of a drive roller which rotates about a first rotation shaft and a driven roller which is driven to rotate about a second rotation shaft with the drive roller, the discharge roller pair discharging a sheet from a side surface of an apparatus main body; a sheet discharge tray arranged selectively either in a first position where the sheet discharge tray is stowed along the side surface of the apparatus main body or in a second position where the sheet discharge tray, swung downward from the first position, protrudes beyond the side surface of the apparatus main body so that the sheet discharged by the discharge roller pair is stackable on the sheet discharge tray; a hook member provided on the sheet discharge tray to be pivotable about a swing shaft, the hook member holding, with the first rotation shaft or the second rotation shaft acting as an engagement shaft, the sheet discharge tray in the first position by engaging with the engagement shaft; and an engagement releasing member fixed to the engagement shaft, the engagement releasing member pressing, by rotation of the engagement shaft, the hook member in a direction away from the engagement shaft, wherein as a result of the discharge roller pair being rotated with the sheet discharge tray located in the first position, the engagement releasing member releases engagement of the hook member with the engagement shaft, and the sheet discharge tray moves to the second position.
