Abstract
A card reader may include a card insertion port; a card passage; and a disturbing magnetic field generator. The disturbing magnetic field generator may include a first disturbing magnetic field generation part and a second disturbing magnetic field generation part which are disposed so as to interpose the card passage. The first disturbing magnetic field generation part may include a first core formed of magnetic material and a coil wound around the first core, and the second disturbing magnetic field generation part may include a second core formed of magnetic material and a coil wound around the second core.
Claims14
A card reader for use with a card having a magnetic stripe, the card reader comprising:
- a card insertion port into which the card is inserted;
- a card passage where the card is passed;
- and
- a disturbing magnetic field generator structured to generate a disturbing magnetic field for disturbing fraudulent reading of magnetic data recorded in the magnetic stripe;
- wherein the disturbing magnetic field generator comprises at least one disturbing magnetic field generation part pair comprised of a first disturbing magnetic field generation part and a second disturbing magnetic field generation part which are disposed so as to interpose the card passage in a thickness direction of the card;
- wherein the first disturbing magnetic field generation part comprises a first core formed of magnetic material and a coil wound around the first core, and the second disturbing magnetic field generation part comprises a second core formed of magnetic material and a coil wound around the second core;
- and
- wherein when an inserting direction side of the card to the card insertion port which is one side in a passing direction of the card is referred to as a rear side, an ejecting direction side of the card from the card insertion port which is the other side in the passing direction of the card is referred to as a front side, an imaginary line passing through a center of a first end face which is one of end faces of the first core and perpendicular to the first end face is referred to as a first imaginary line, and an imaginary line passing through a center of a second end face which is one of end faces of the second core and perpendicular to the second end face is referred to as a second imaginary line, the first core and the second core are disposed so that, when viewed in a width direction of the card perpendicular to the passing direction of the card and a thickness direction of the card, the first imaginary line and the second imaginary line are inclined with respect to the passing direction of the card so as to approach each other toward the front side and intersect each other on the front side with respect to the card insertion port and intersect each other at a position displaced from a passing position of the card in the thickness direction of the card.

- a card passage where the card inserted from the card insertion port is passed;
- and
- a disturbing magnetic field generator structured to generate a disturbing magnetic field for disturbing fraudulent reading of magnetic data recorded in the magnetic stripe;
- wherein the disturbing magnetic field generator comprises a core formed of magnetic material and a coil wound around the core;
- wherein when an inserting direction side of the card to the card insertion port which is one side in a passing direction of the card is referred to as a rear side, an ejecting direction side of the card from the card insertion port which is the other side in the passing direction of the card is referred to as a front side, an imaginary line passing through a center of a first end face which is one of end faces of the core and perpendicular to the first end face is referred to as a first imaginary line, and an imaginary line passing through a center of a second end face which is the other of the end faces of core and perpendicular to the second end face is referred to as a second imaginary line, the core is formed so that the first end face and the second end face are directed to a substantially front side in the passing direction of the card and that the first end face and the second end face are disposed so as to interpose the card passage in a thickness direction of the card;
- and
- wherein when viewed in a width direction of the card perpendicular to the passing direction of the card and the thickness direction of the card, the first imaginary line and the second imaginary line are inclined with respect to the passing direction of the card so as to approach each other toward the front side and intersect each other on the front side with respect to the card insertion port and intersect each other at a position displaced from a passing position of the card in the thickness direction of the card.
