CARD READER

A card reader is provided which is capable of detecting a skimming magnetic head attached to a front side of a card insertion member formed with a card insertion port and a skimming magnetic head attached to an inclined face of the card insertion port with a simple structure. The card reader includes a card insertion member 8 formed with a card insertion port 3 and a light emitting element 9 and a light receiving element for detecting that a foreign matter has been attached to the card insertion member 8. A lower face of the card insertion port 3 is formed to be an inclined face 3a which is inclined toward a lower side as going to the front side. Light emitted from the light emitting element 9 is incident on the inclined face 3a from a rear side and the lower side and is refracted at the inclined face 3a and is emitted from the inclined face 3a toward at least the front side. Light emitted from the light emitting element 9 and reflected on the front side and an upper side of the inclined face 3, and light emitted from the light emitting element 9 and reflected on the front side with respect to the card insertion member 8 are incident on the light receiving element.
