Abstract

A disclosed paper folding device is capable of processing paper sheets consecutively and designed to stop supplying the paper sheets into a paper conveying path and to stop a paper folding process when a paper jam occurs. The paper folding device includes a paper folding unit configured to perform the paper folding process; a first paper detecting unit configured to detect a remaining paper sheet remaining at a first position in the paper conveying path when the paper jam occurs; and a remaining paper conveying unit configured to perform a conveying process for conveying the remaining paper sheet detected by the first paper detecting unit from the first position to a second position in the paper conveying path.
