1. A paper sheet processing apparatus, comprising:
a processing tray for receiving and stacking a plurality of paper sheets;
a feed member that is rotatably arranged above the processing tray to face the processing tray and includes a paddle elastically deformed by being pressed against the paper sheets during rotation to scrape the paper sheets stacked on the processing tray toward an alignment surface by the paddle;
a drive component that rotates the feed member;
a detector arranged between the feed member and the alignment surface and that detects a leading end of the paper sheet being fed toward the alignment surface by the paddle;
a controller for controlling the drive component based on a detection result of the detector during a period from detecting the leading end of the paper sheet to separating from the paper sheet, and for controlling the rotation of the feed member so that the leading end of the paper sheet scraped by the paddle is aligned with the alignment surface; and
a memory storing an optimal control value for the feed member based on a thickness of the paper sheet detected by the detector, wherein
the controller reads out the optimal control value from the memory based on the detection result and controls the drive component according to the control value.
