Abstract
Provided is a card insertion unit for a card reader which, without weakening a magnetic field generated by a magnetic field generating device in order to prevent reading of magnetic data by a magnetic head for skimming, is capable of reducing the effect of the magnetic field upon the reading of the magnetic data by way of the magnetic head for data reading. This card insertion unit may be provided with a notch formed at a point at which a magnetic stripe passes at insertion time of the card a projecting portion which projects toward the upstream side of the insertion direction of the card and a magnetic field generating device disposed in the interior of the projecting portion.
Claims8
A card insertion part for a card reader into which a card having a magnetic stripe is to be inserted, the card insertion part comprising:
- a cut-off part which is formed at least at a portion where the magnetic stripe passes when the card is inserted;
- a protruded part which is adjacent to the cut-off part in a widthwise direction of the card which is substantially perpendicular to an inserting direction of the card and is protruded toward an upstream side in the inserting direction of the card;
- and
- a magnetic field generation device which is disposed in an inside of the protruded part and is structured to generate a magnetic field;
- wherein the magnetic field generation device comprises a core formed of magnetic material and a coil wound around the core;
- and
- wherein the magnetic field generation device is disposed so that magnetic lines of force indicating the magnetic field generated by the magnetic field generation device are passed through a position where the magnetic stripe is passed when the card is inserted and so that a direction of the magnetic lines of force coming out from an end face of the core and/or a direction of the magnetic lines of force entering into an end face of the core are inclined with respect to the inserting direction of the card.
