Abstract

Provided are a medium conveyance apparatus, control method, and control program to enable determining whether multi-feed of a medium has occurred by a greater precision. A medium conveyance apparatus includes a storage device to store in advance region information of a predetermined region in a medium, a feed roller to feed the medium, a slant detection module to detect an amount of slant of the fed medium, an overlap detection module to detect region information of a region in which overlap has occurred in the fed medium, a correction module to correct the detected region information based on the amount of slant, and a multi-feed determination module to determine that multi-feed of the medium has occurred if the corrected region information does not correspond to the stored region information and determine that multi-feed of the medium has not occurred if the corrected region information corresponds to the stored region information.
