Zusammenfassung:	A paper conveying apparatus (100, 200) including a sound signal generator (141, 241) for generating a sound signal, a sound jam detector (153) for determining whether a jam has occurred based on the sound signal, a special sound detector (156) for determining whether a special sound has been generated based on a component of the sound signal, and a control module (151) for performing abnormal processing when the sound jam detector (153) determines that a jam has occurred and the special sound detector (156) determines that a special sound has not been generated, and determining that no jam has occurred and not performing the abnormal processing when the sound jam detector (153) determines that a jam has occurred and the special sound detector (156) determines that a special sound has been generated.
