Document Type and Number:
Japanese Patent JP7349585
Kind Code:
B2
Abstract:
Provided are a medium conveying apparatus, a control method, and a control program to enable determining whether multi-feed of the medium has occurred with higher accuracy. A medium conveying apparatus includes a conveying module to convey a medium, a detection module to detect transmission information of ultrasonic waves transmitted through the medium or thickness information of the medium at a plurality of positions in the medium conveyed by the conveying module, a determination module to determine whether multi-feed of the medium has occurred, by comparing a value based on the transmission information or the thickness information with a threshold, for each of the plurality of positions, and a control module to execute an abnormality process when it is determined that multi-feed of the medium has occurred. The determination module changes a determination sensitivity of whether multi-feed of the medium has occurred, according to a position in the medium at which the transmission information or the thickness information has been detected by the detection module.
