Abstract
A sheet ejecting device having a pair of ejection rollers, a strengthener provided in a sheet ejection route, a tray for receiving ejected sheets and a driver for lifting up and down the tray. A sheet is ejected via the ejection rollers while being strengthened by the strengthener. A specified time after the sheet comes into contact with a stack of sheets on the tray, the tray is lifted up so that the contact point between the currently ejected sheet and the stack of sheets on the tray becomes nearer to the pair of ejection rollers.
Claims10
A sheet ejecting device for ejecting printed sheets one by one, said device comprising:
- a pair of ejection rollers for engaging a sheet to thereby eject the sheet;
- a strengthener, provided in a sheet ejection route, for strengthening a currently engaged sheet by providing a force for the currently engaged sheet;
- a tray for receiving sheets ejected via the pair of ejection rollers and holding the sheets in a stack;
- and
- a mechanism for changing a distance between a contact point of the currently engaged sheet, which is a sheet currently engaged by the pair of ejection rollers, with the stack of sheets held on the tray and the pair of ejection rollers to thereby reduce the force provided for the currently engaged sheet by the strengthener.
A sheet ejecting device for ejecting printed sheets one by one, said device comprising:
- a pair of ejection rollers for engaging a sheet to thereby eject the sheet;
- a strengthener, provided in a sheet ejection route, for strengthening a currently engaged sheet by providing a force for the currently engaged sheet;
- a tray for receiving sheets ejected via the pair of ejection rollers and holding the sheets in a stack;
- and
- at least one of a driver for lifting up and down the tray, a driver for changing an angle of the tray to the sheet ejection route and a driver for changing a sheet ejection angle,
- wherein the at least one of the drivers lifts up the tray, increases the angle of the tray to the sheet ejection route or changes the sheet ejection angle so that a contact point of the currently engaged sheet, which is a sheet currently engaged by the pair of ejection rollers, with the stack of sheets held on the tray becomes nearer to the pair of ejection rollers to thereby reduce the force provided for the currently engaged sheet by the strengthener.
