ABSTRACT:
A technology that is applicable generally to manual noncontact card readers regardless of whether they are of insertion or swipe type, and realizes stable communication even with antennas of small size is provided. A pair of loop antennas is located in opposition to either side of a transport path, in proximity to a card insertion slot of the transport path. A magnetic circuit which connects the loop antennas together is located so as to not lie exposed in the transport path, so that, of the magnetic fluxes produced in two directions with respect to the noncontact card from the loop antennas, one of these will be diverted through the magnetic circuit without interlinking to the card.
