Abstract

A sheet post-processing device includes a conveying member, a processing tray, a processing section, a reference plate, an alignment member, a holder drive unit, and a control unit. The alignment member includes a paddle holder supported in a swingable manner along a carry-in direction, and an alignment paddle supported in a rotatable manner at a swinging end of the paddle holder. The holder drive unit moves the alignment paddle in a reciprocating manner, between a reference position to retreat the paddle part above a top sheet placed on the processing tray and an acting position to allow the paddle part to contact with a top surface of the sheet. When the number of the sheets carried in onto the processing tray is increasing, the control unit continuously moves the acting position of the alignment paddle in a direction separating from the processing tray.
