Abstract
A sheet collecting apparatus has a sheet transport path for transporting a sheet, a tray device for bearing and storing sheets, a regulation stopper for regulating the sheet, a holding path to temporarily hold a sheet, an alignment roller to transport the sheet, and a control device for controlling transport of the sheet. The alignment roller adjusts a level of pressing force acting on the sheet transported onto the tray device. The control device has a first operation mode and a second operation mode. In the first operation mode, the alignment roller applies a transport force to the sheet by a predetermined pressing force after a rear end of the sheet is carried into the tray device, while in the second operation mode, changing the pressing force applied to the sheets from the alignment roller from a first pressing force to a second pressing force and applying varied transport force.
