Abstract:
A paper sheet feeder comprising:paper conveying means having a motor, for conveying paper of different lengths along a paper feeding route; a paper detection sensor provided in the paper feeding route; and control means for stopping drive of the motor after the paper has passed the paper detection sensor so that the paper is stopped at a position downstream of the paper detection sensor in which a trailing end of the paper is engaged with a paper return prevention lever, and then for accommodating the paper thus stopped in a stacker, wherein the control means controls drive time of the motor after the paper has passed the paper detection sensor, based on time interval required for the paper to pass through a certain sector of the paper feeding route positioned upstream from the paper detection sensor, whereby each of the papers of different lengths stops at the position in which the trailing end of the each of the papers is engaged with the paper return prevention lever so that when the papers of different lengths thus stopped are accommodated in the stacker, the papers of different lengths can be engaged with the paper return prevention lever, thereby to prevent jamming of the papers.
