Abstract
There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium that can suppress erroneous detection of an occurrence of a jam by sound due to the sound generated along with conveyance of a paper. The paper conveying apparatus includes a first sound signal generator for generating a first sound signal corresponding to a sound generated by a paper during conveyance, at least a part of the first sound signal generator is provided at one end of a conveyance path of the paper, a second sound signal generator for generating a second sound signal corresponding to the sound, at least a part of the second sound signal generator is provided at the other end of the conveyance path, and a sound jam detector for determining whether a jam has occurred based on a difference of the first sound signal and the second sound signal.
