PAPER CONVEYING APPARATUS, JAM DETECTION METHOD, AND COMPUTER PROGRAM

摘要

Provided is a paper transporting device and the like capable of suppressing errors in determining jam occurrences. A paper transporting device has: a transport mechanism; an audio signal output unit that outputs an audio signal according to the sound generated during paper transport; an audio jam determination unit that determines, on the basis of the audio signal, whether a jam has occurred; and a control unit that stops paper transport when the audio jam determination unit determines that a jam has occurred. The control unit controls, in the case of card stock or paperboard being transported by the transport mechanism, so that the audio jam determination unit determines whether a jam has occurred at predetermined times using a determination method that is different than the method at other times or so that the audio jam determination unit does not determine whether a jam has occurred.

主权项

1. A paper conveying apparatus comprising:
a conveyor mechanism; a sound signal generator 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 the sound signal; and a control module for stopping conveyance of a paper when the sound jam detector determines that a jam has occurred, wherein the control module controls so that the sound jam detector determines whether a jam has occurred at a predetermined timing by a determining method different from a determining method at other timings, or so that the sound jam detector does not determine whether a jam has occurred, when a card or thick paper is conveyed by the conveyance mechanism.
