Abstract: An MR sensor structured to detect whether or not magnetic data are recorded in a magnetic stripe of a card having first and second tracks may include a first resistor and a second resistor serially-connected with each other and disposed at positions where the first track is passed; and a third resistor and a fourth resistor serially-connected with each other and disposed at positions where the second track is passed. The second resistor and the fourth resistor may be connected with a power supply, and the first resistor and the third resistor may be ground grounded. A potential difference between a first midpoint between the first resistor and the second resistor and a second midpoint between the third resistor and the fourth resistor may be an output of the MR sensor.

Abstract: A card reader may include a magnetic sensor to detect whether magnetic data are recorded in the magnetic stripe of the card; a control section to supply electric power to the magnetic sensor and into which an output signal of the magnetic sensor is inputted; and a card insertion port into which the card is inserted and in which the magnetic sensor is disposed. The magnetic sensor may output an output signal when the electric power is supplied from the control section. The control section may supply the electric power to the magnetic sensor during a first supply time period which is shorter than a card passage time period.
