Abstract
A stacker ( ) includes a housing ( ) provided with an inlet port ( ) and an outlet port ( ), a tray ( ) arranged beneath the outlet port of the housing in an upward/downward movable manner, and a transfer mechanism for transferring printed sheets from the inlet port to the outlet port and discharging the sheets above the tray through the outlet port. The sheet transfer velocity of the transfer mechanism is controlled in three stages including an intake speed (V ) at which the printed sheets are taken in through the inlet port, a carrying speed (V ) at which the sheets are carried from the inlet port to the outlet port and a discharge speed (V ) at which the sheets are discharged from the outlet port above the tray. The carrying speed is higher than the intake speed, and the discharge speed is not lower than the carrying speed. As a result, even when a concavely curled paper, taken in from the printer, is carried in a face-up state to be discharged above the tray, the paper can be prevented from leaning against the back plate of the housing, and thereby the problem of a loading failure of the papers during an automatic operation can be solved.
