Title:
DOCUMENT CONVEYING DEVICE, METHOD FOR DETERMINING JAM, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/087453
Kind Code:
A1
Abstract:
Provided is a document conveying device, etc. capable of suppressing errors in sound-based determination of the occurrence of a jam which are caused by sounds generated by a moving member that is driven in association with the conveyance of documents. The document conveying device comprises: the moving member, which is driven in association with the conveyance of documents; a drive unit that drives the moving member; a sound signal output unit that outputs a sound signal corresponding to a sound generated during the conveyance of documents; a sound jam-determination unit that determines, on the basis of the sound signal, whether or not a jam has occurred; and a control unit that stops the conveyance of documents when the sound jam-determination unit determines that a jam has occurred. The control unit performs control so that while the drive unit is driving the moving member, the sound jam-determination unit determines whether or not a jam has occurred using a method different from that used when the drive unit is not driving the moving member, or so that the sound jam-determination unit does not determine whether or not a jam has occurred.
