Abstract
When discharging a sheet onto a discharge tray, a control unit sets position of the discharge tray in an up and down direction to a predetermined discharge position. When loading the sheet onto a processing tray, the control unit sets the position of the discharge tray in the up and down direction to a loading position lower than the discharge position.
Claims8
A sheet post-processing device, comprising:
- a processing tray disposed inside a device main body, so that a sheet is loaded on the processing tray;
- a post-processing section that performs predetermined post-processing on the sheet loaded on the processing tray;
- a discharge outlet through which the sheet on the processing tray is discharged;
- a discharge tray disposed movably along a side face of the device main body extending downward below the discharge outlet, so that the sheet discharged through the discharge outlet is loaded on the discharge tray;
- a discharging member that conveys the sheet on the processing tray toward the discharge outlet, and discharges the sheet onto the discharge tray through the discharge outlet;
- a lifting mechanism that drives the discharge tray to move in an up and down direction;
- and
- a control unit that controls the movement of the discharge tray in the up and down direction driven by the lifting mechanism;
- an intermediate roller pair including a pair of rollers in pressed contact with each other, the intermediate roller pair rotating with the sheet nipped between the pair of rollers to convey the sheet toward the discharge outlet and then make a front end of the sheet protrude above the discharge tray via the discharge outlet;
- and
- a pull-in member that, after a rear end of the sheet conveyed by the intermediate roller pair has passed through the intermediate roller pair, switches back the sheet with the front end of the sheet protruding above the discharge tray via the discharge outlet, the pull-in member thereby pulling in the sheet to load the sheet onto the processing tray, wherein
- when discharging the sheet onto the discharge tray, the control unit sets position of the discharge tray in the up and down direction to a predetermined discharge position, and
- when loading the sheet onto the processing tray, the control unit sets the position of the discharge tray in the up and down direction to a loading position lower than the discharge position.
