Abstract
There are provided a paper conveying apparatus that can precisely determine the presence of occurrence of a jam by a jam sound. The paper conveying apparatus includes an analog sound signal generator for generating an analog sound signal corresponding to a sound generated by the paper during conveyance of the paper, a corrected signal generator for generating a signal acquiring the peak hold of the analog sound signal or a signal detecting the analog sound signal as a corrected signal, a digital converter for sampling the corrected signal and converting the corrected signal to a digital format to generate a digital sound signal, and a sound jam detector for determining whether a jam has occurred based on the digital sound signal.
