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

摘要

There is provided the paper conveying apparatus, jam determining method, and computer program, which can suppress the mistaken determining of the occurrence of a jam by sound due to a sound generated by a moving member driven in relation to conveyance of a paper. The paper conveying apparatus according to an embodiment includes a moving member driven in relation to conveyance of a paper, a drive module for driving the moving member, 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. The control module controls so that the sound jam detector determines whether a jam has occurred by a determining method different from a determining method used while the drive module is not driving the moving member, or the sound jam detector does not determine whether a jam has occurred, while the drive module is driving the moving member.

1. A paper conveying apparatus comprising:
a moving member driven in relation to conveyance of a paper; a drive module for driving the moving member; 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 by a determining method different from a determining method used while the drive module is not driving the moving member, or the sound jam detector does not determine whether a jam has occurred, while the drive module is driving the moving member.
