Abstract: A card reader device A1 includes: a housing 11; an openable shutter 311 that allows or disallows passing of a magnetic card C into the housing 11; a magnetic head 511 that reads magnetic data of the magnetic card C received in the housing 11; an interfering magnetic field generator 711 provided on a rear surface side of the shutter 311 to generate an interfering magnetic field in at least a region R between the magnetic head 511 and the shutter 311; an interfering magnetic field control unit 61 that controls generation of the interfering magnetic field; and an interfering magnetic field alleviating unit 81 that alleviates an influence of the interfering magnetic field on the magnetic head 511 so that the interfering magnetic field generated by the interfering magnetic field generator 711 does not interfere the reading of the magnetic data by the magnetic head 511.

Abstract: From the detection result of a sensor for detecting a card, whether or not the card exists in the inside, and whether or not the card exists in a return area are determined, respectively, and in the state where it is determined that the card exists in the inside, if the time counted by a first timer has reached a time while a command from a host system is not received by a communication unit, then it carries out the communication error process of addressing that the command is not received. That is, the card in the inside is returned to the area, and subsequently, in the state that it is determined that the returned card exists in the area, if the time counted by a second timer reaches a second time while the card is not taken out from the area, the card is taken to the inside.

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.

Abstract: In a card processor having a function of intermittently transporting a magnetic card, card information is prevented more effectively from being illegally acquired by a skimmer mounted on a card slot. Transport rollers are mounted near the card slot. When a sensor turns ON as a card is inserted into the card slot, the transport rollers are intermittently driven to intermittently transport the card and fetch it in the card processor. Since the card is intermittently transported approximately at the same time when the card is inserted, even if a skimmer SK is mounted on the card slot, information skimmed with a magnetic head H of the skimmer SK during card insertion is only little information in a range a, and most of information will not be skimmed.

Abstract: A card processing device (100) that handles a magnetic card and an IC card wherein, when a card (50) is taken into a main body (20) and if the card is a magnetic card, the inserted card (50) is taken in by intermittently transporting the card to a predetermined position and, after that, by continuously transporting the card and, if the card is an IC card, the inserted card (50) is taken in by continuously transporting the card. When the card (50) is ejected out of the main body (20) and if the card is a magnetic card, the card is ejected by continuously transporting the card to a predetermined position and, after that, by intermittently transporting the card and, if the card is an IC card, the card is ejected by continuously transporting the card.

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 22a, 22b is located in opposition to either side of a transport path 2, in proximity to a card insertion slot 3 of the transport path 2. A magnetic circuit 40 which connects the loop antennas 22a, 22b together is located so as to not lie exposed in the transport path 2, so that, of the magnetic fluxes produced in two directions with respect to the noncontact card from the loop antennas 22a, 22b, one of these will be diverted through the magnetic circuit 40 without interlinking to the card.

Abstract: A method and apparatus are disclosed for determining an appropriate write current for a magnetic recording medium and to write magnetic information on the magnetic recording medium at the appropriate write current thus determined. When a current value suited to writing on a magnetic recording medium is to be found, a coercive force of the magnetic recording medium is found from a voltage at which magnetic information written on the magnetic recording medium is read, and a traveling quantity of the magnetic recording medium, and a current value corresponding to the coercive force, are found.
