Paper conveying apparatus with side guide and sound detector

摘要

There are provided a paper conveying apparatus which can effectively detect a sound which is generated when a jam occurs for various types of jams. The paper conveying apparatus includes a side guide, arranged to be movable in a direction which is perpendicular to a conveyance direction of a paper placed on a paper tray, for restricting a width direction of the paper, a sound signal generator, provided at the side guide so that a sound detector moves in accordance with movement of the side guide, for generating a sound signal corresponding to a sound generated by the paper during conveyance of the paper, and a sound jam detector for determining whether a jam has occurred based on the sound signal.
