CARD READER

摘要

A card reader may include a card passage where a card inserted into an insertion port for the card is passed, a shutter member for closing the card passage, a magnetic head disposed on a rear side relative to the shutter member and structured to perform reading of magnetic data recorded in a magnetic stripe of the card and/or recording of magnetic data to the magnetic stripe, and a foreign matter detection mechanism which is structured to detect a foreign matter attached to the card passage. The foreign matter detection mechanism is disposed on a rear side relative to the shutter member and is disposed at a position in the width direction of the card where the magnetic stripe is passed. The foreign matter detection mechanism may be structured of an electrostatic capacitance sensor.

1. A card reader for use with a card comprising a magnetic stripe, the card reader comprising:
a card passage where the card inserted into an insertion port for the card is passed; a shutter member structured to close the card passage; a magnetic head which is disposed on a rear side relative to the shutter member and is structured to perform reading of magnetic data recorded in the magnetic stripe of the card and/or recording of magnetic data to the magnetic stripe; and a foreign matter detection mechanism which is structured to detect a foreign matter attached to the card passage; wherein, when a direction perpendicular to a thickness direction of the card inserted into the insertion port and a passing direction of the card is referred to as a width direction of the card, the foreign matter detection mechanism is disposed on a rear side relative to the shutter member and is disposed at a position in the width direction of the card where the magnetic stripe is passed.
