Abstract
A transmitter transmits ultrasound to the conveyance path. A receiver receives the ultrasound. A double-feed detector detects whether or not double-feed of a plurality of sheets has occurred. A controller causes the transmitter to transmit ultrasound at a first burst interval when determining the threshold value, and causes the transmitter to transmit ultrasound at a second burst interval, which is shorter than the first burst interval, when detecting the double-feed of sheets. A double-feed detector determines a threshold value that enables distinction between double-feed and single-feed.
