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 precisely determine any occurrence of a jam by a sound which is generated by paper for various types of paper. The paper conveying apparatus includes a sound signal generator, provided with a sound detector near a conveyance path of a paper, for generating a sound signal corresponding to a sound generated by a paper during conveyance of the paper, a paper thickness setting module for setting a thickness of a paper conveyed to the conveyance path, and a sound jam detector for determining whether a jam has occurred based on a signal of a specific frequency band in the sound signal, wherein the sound jam detector determines the specific frequency band based on a thickness of the paper.

1. A paper conveying apparatus comprising:
a sound signal generator, provided with a sound detector near a conveyance path of a paper, for generating a sound signal corresponding to a sound generated by a paper during conveyance of the paper; a paper thickness setting module for setting a thickness of a paper conveyed to the conveyance path; and a sound jam detector for determining whether a jam has occurred based on a specific frequency band in the sound signal, wherein the sound jam detector decides that the specific frequency band is a first frequency band when the thickness of the paper is a first thickness, and decides that the specific frequency band is a second frequency band higher than the first frequency band when the thickness of the paper is a second thickness thinner than the first thickness.
