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 that can suppress erroneous detection of a jam by sound due to the sound which a paper which has a wrinkle generates. The paper conveying apparatus includes a separator, a sound signal generator, provided with a sound detector provided at a downstream side of the separator, for generating a sound signal in accordance with the sound generated by a paper during conveyance, a sound jam detector for determining whether a jam has occurred based on the sound signal, and a wrinkle detector, provided at a downstream side of the separator, for detecting optically a wrinkle of a paper, wherein the sound jam detector changes the method of detection of the jam when the wrinkle detector detects a wrinkle of a paper.

主权项

1. A paper conveying apparatus comprising:
a separator; an image reader for reading an image from a paper separated by the separator; a sound signal generator including a sound detector provided at a downstream side of the separator in a paper conveyance direction, 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, using a detection method; and a wrinkle detector, provided at a downstream side of the separator in the paper conveyance direction, for optically detecting a wrinkle of the paper, wherein the sound jam detector changes the detection method when the wrinkle detector detects the wrinkle of the paper, and the image reader is utilized as the wrinkle detector.
