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

The invention provides a card reader and a control method of the card reader. The card reader can detect whether magnetic data is recorded in the magnetic stripe of the card inserted from the card insertion port, prevent criminals from obtaining magnetic information illegally, and reduce the cost. The card reader has: a magnetic sensor (8) for detecting whether magnetic data is recorded in the magnetic strip of the card; and a control unit that supplies power to the magnetic sensor (8) and receives an input of an output signal of the magnetic sensor (8) (14), if the magnetic sensor (8) is supplied with power from the control unit (14), it outputs an output signal. When the recording area of ​​the magnetic data recorded in the magnetic stripe of the card inserted from the card insertion port starts to pass through the magnetic sensor (8) and the time until the end of passing through is set as the card passing time, the control unit (14) sends a signal to the magnetic sensor (8). ) power supply for a first supply time shorter than the card passing 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...
