Check multifeed detection apparatus for use in a check processing terminal and detection method

A check multifeed detection apparatus for use in a check processing terminal including a paper supply unit for individually feeding a plurality of checks;

• a check transportation unit for conveying each check fed from said paper supply unit along a check transportation path in a given direction and;
• a MICR head disposed on one side of the check transportation path having a non-movable contact surface, said check multifeed detection apparatus comprising:
• a pressure member having a pressure portion disposed on another side of the check transportation path at a first position opposite to said non-movable contact surface for pressing one or more transported checks passing therebetween against said MICR head;
• a detection surface located on said pressure member at a second position laterally separated from said first position;
• and
• a displacement detection sensor in opposing juxtaposition to said detection surface for detecting the physical displacement of the pressure member from said non-movable contact surface to detect multifeeding of transported check(s) according to the thickness of the transported check(s).
