Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0026] (Structure of the card reader)

[0027] figure 1 It is a schematic diagram of the card reader 1 which concerns on embodiment of this invention. figure 2 With figure 1 A block diagram of the controller 14 to which the magnetic sensor 8 is connected is shown. image 3 is used for figure 1 A diagram for explaining the on-off timing of the magnetic sensor 8 is shown.

[0028] The card reader 1 of this embodiment is a device for reading magnetic data recorded on the card 2 or recording magnetic data on the card 2 , and is used by being installed in a predetermined high-level device such as an automatic teller machine, for example. The card reader 1 has a card insertion part 4 and a main body part 5, and the card insertion part 4 is formed with a card insertion opening 3 for inserting a card 2 therein. A card passage through which the card 2 inserted through the...

Abstract

Provided is a card reader with which the illegitimate acquisition of magnetic information by a criminal can be prevented even when it is possible to determine whether magnetic data has been recorded on the magnetic stripe on a card that has been inserted from a card insertion port, and with which the cost can be reduced, and a method for controlling the card reader. This card reader is equipped with a magnetic sensor (8) for detecting whether magnetic data has been recorded on the magnetic stripe of a card, and a control unit (14) that supplies power to the magnetic sensor (8) and receives an input of an output signal from the magnetic sensor (8). The magnetic sensor (8) outputs an output signal when power is supplied from the control unit (14). When the card transit time is defined as the time from when a recording region for magnetic data recorded on the magnetic stripe on a card inserted into the card insertion port begins to pass by the magnetic sensor (8) until the time when the recording region finishes passing by, the control unit (14) supplies power to the magnetic sensor (8) for a first supply time that is shorter than the card transit time.

Description

technical field [0001] The invention relates to a card reader having a magnetic sensor for detecting whether magnetic data is recorded in a magnetic strip of a card. Moreover, the present invention relates to a control method of the card reader. Background technique [0002] Conventionally, a card reader for reading magnetic data recorded on a card is known (for example, refer to Patent Document 1). The card reader described in Patent Document 1 has a magnetic head for reading magnetic data recorded on a card. In addition, the card reader has a pre-head (magnetic head) for detecting whether or not magnetic data is recorded on the magnetic stripe of the card inserted from the card slot. [0003] In the industry using card readers, so-called tapping (tapping), in which criminals illegally obtain signals output from a pre-reading head to illegally obtain magnetic information recorded on a card, has been a big problem in the past. In the card reader described in Patent Docume...
