Paper conveying apparatus, jam detection method, and computer-readable, non-transitory medium

摘要

There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium which can suppress erroneous detection of the occurrence of a jam. The paper conveying apparatus includes a sound signal generator, provided with a sound detector near a conveyance path of paper, for generating a sound signal corresponding to a sound generated by a paper during conveyance of the paper, a sound jam detector for determining whether a jam has occurred based on a predetermined sound signal, and a control module for performing an abnormal processing when the sound jam detector determines that the jam has occurred and the predetermined sound signal is not generated at a predetermined timing, and determining that the jam has not occurred and not performing the abnormal processing when the sound jam detector determines that the jam has occurred and the predetermined sound signal is generated at the predetermined timing.

1. A paper conveying apparatus comprising:
a separator; a sound signal generator, provided with a sound detector near a conveyance path of paper, for generating a sound signal corresponding to a sound generated by a paper during conveyance of the paper; a sound jam detector for determining whether a jam has occurred based on a predetermined sound signal; and a control module for performing an abnormal processing based on the jam detection by the sound jam detector, wherein the control module determines that the jam has not occurred and does not perform the abnormal processing when the sound jam detector determines that the jam has occurred and the predetermined sound signal is generated at a time at which a back end of a card or a thick paper, detected by the sound jam detector, passes the separator when conveyed paper is the card or the thick paper.
