MULTIFEED PROCESSING APPARATUS, MULTIFEED PROCESSING METHOD, AND MULTIFEED PROCESSING PROGRAM

A multifeed processing apparatus includes a control unit and a storage unit and is connected to a multifeed detecting mechanism and an image reading mechanism. The control unit includes (i) a measuring unit that measures a multifeed detection pattern from any one or both of an output of the multifeed detecting mechanism and an image of a medium read by the image reading mechanism, (ii) a determining unit that determines whether the measured multifeed detection pattern is included in a multifeed disable pattern stored in the storage unit, (iii) a reading control unit that regards a multifeed detection performed by the multifeed detecting mechanism as invalid, and causes the image reading mechanism to continue a reading operation, and (iv) a storage control unit that stores the measured multifeed detection pattern as the multifeed disable pattern in the storage unit.
