Card reader

A card reader for use with a card configured to record magnetic data, the card reader comprising:

• a magnetic head configured to read magnetic data recorded on the card or record magnetic data to the card;
• a card insertion part comprising an insertion port into which the card is inserted;
• an infrared sensor configured to detect a human body which is disposed on a front face side of the card insertion part and configured to detect movement of a person in front of the card reader;
• a card passage where the card is passed;
• and
• a card sensor for detecting presence/absence of the card in the card passage;
• wherein the infrared sensor is disposed at substantially a same position as an arrangement position of the magnetic head in a widthwise direction of the card which is substantially perpendicular to an inserting direction of the card;
• wherein the magnetic head is disposed so that its gap part faces the card passage,
• wherein the infrared sensor is disposed on a side where the magnetic head is disposed with respect to the card passage in a thickness direction of the card which is substantially perpendicular to an inserting direction of the card and which is substantially perpendicular to a widthwise direction of the card that is substantially perpendicular to the inserting direction of the card, and
• wherein, when the card sensor detects the card in a state that the infrared sensor does not detect movement of a person, an abnormal signal is transmitted to a host device on which the card reader is mounted.

A card reader for use with a card configured to record magnetic data, the card reader comprising:

• a magnetic head configured to read magnetic data recorded on the card or record magnetic data to the card;
• a card insertion part comprising an insertion port into which the card is inserted;
• and
• a metal sensor configured to detect attachment of a foreign matter including metal material to a front face side of the card insertion part;
• wherein the metal sensor comprises a core which is formed of magnetic material, and a pair of excitation coils and a detection coil which are wound around with a center axis of the core as a center;
• wherein the core is provided with a center core part which is disposed at a substantially center in an axial direction of the center axis and a pair of axial end core parts which are disposed on both end sides of the center core part in the axial direction of the center axis, and the detection coil is wound around the center core part and each of the pair of the excitation coils is wound around each of the pair of the axial end core parts;
• and
• wherein the metal sensor is disposed at substantially a same position as an arrangement position of the magnetic head in a widthwise direction of the card which is substantially perpendicular to an inserting direction of the card.
