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 memberformed with a card insertion portand a light emitting elementand a light receiving element for detecting that a foreign matter has been attached to the card insertion memberA lower face of the card insertion portis formed to be an inclined facewhich is inclined toward a lower side as going to the front side.

Card reader

A card reader may include a wireless user interface; a host connecting interface structured to connect with the host device of the system; and a wireless communication interface structured to connect with the mobile terminal. The wireless user interface may be structured to communicate with the host device through the host connecting interface and with the mobile terminal through the wireless communication interface.

Provided is a card insertion and ejection mechanism to be mounted forward of a card reader structured to convey a card so that a longitudinal direction of the card is coincided with a conveying direction of the card, the card insertion and ejection mechanism being capable of preventing skimming and capable of sending into the card reader the card in an orientation capable of being processed by the card reader even when the card is inserted into the card insertion and ejection mechanism in any orientation. A card insertion and ejection mechanism takes in a card to a turning position when the card is inserted into a card insertion port with front and rear sides of the card directed correctly so that a short widthwise direction of the card is coincided with an 'X' direction, and controls a card turning and conveying mechanism in a turning direction and at a turning angle based on a result of determination as to an orientation of the inserted card, to turn the card. The card insertion and ejection mechanism does not take in the card when the card is inserted into the card insertion port so that a longitudinal direction of the card is coincided with the 'X' direction or when the card is inserted into the card insertion port with the front and rear sides of the card directed oppositely.

Card insertion and ejection mechanism and card processing device

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.

Card reader and control method therefor

A card reader may include a card insertion port; a magnetoresistive (MR) sensor; and a disturbing magnetic field generator, wherein the card may include a magnetic stripe, and magnetic data recorded in the magnetic stripe may be arranged in a moving direction of the card inserted through the card insertion port. The MR sensor may include a first resistor and a second resistor separated by a distance which is less than a bit interval of magnetic data, in a case that '0' data are recorded in the magnetic stripe, in the moving direction of the card.

A card reader may include an IC contact block; an insertion port; an insertion posture detection mechanism; a tip end detection mechanism; a pulling-out prevention mechanism structured to prevent pulling-out of a card inserted in an inside of the card reader when it is detected that the card is inserted into the insertion port in a correct posture based on a detected result of the insertion posture detection mechanism and, when it is detected that the tip end face of the card in the inserting direction has been inserted to the predetermined position based on a detected result of the tip end detection mechanism; and a pushing-out mechanism structured to push out the card inserted into the inside of the card reader in an ejecting direction of the card which is an opposite direction of the inserting direction.

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.

MR sensor and card reader

A card reader may include a card conveying mechanism; a guide; a magnetic head; a positioning member to position the card relative to the magnetic head; and a shutter. The positioning member may include a card abutting part to abut a third direction end of the card; and a card support part to contact a first direction side of the card. A distance between the card abutting part and a third direction end of the guide is shorter than a width in the short-side direction of the card. When the shutter has closed, a fourth direction end of the shutter is disposed on a first direction side of the guide. When the shutter has opened the opening, the shutter is disposed on the first direction side of the guide. The third direction end of the card may be guided to the card support part by the shutter.

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.

A card reader may include a card insertion part which is formed with an insertion port into which the card is inserted; and a magnetic sensor which is provided in the card insertion part and is structured to detect whether magnetic data are recorded on the card or not. The magnetic sensor may be disposed so as to secure a space between the card inserted into the insertion port and the magnetic sensor. The magnetic data may be arranged in a longitudinal direction of the card. When viewed in a thickness direction of the card which is inserted into the insertion port, a magnetism detection direction of the magnetic sensor may be inclined with respect to a direction perpendicular to the longitudinal direction.

The conveying passage may be formed with an opening part through which the magnetic head is passed. The magnetic head may be located at the head abutting position and is abutted with the one face of the card at a time when the IC contact springs and the external connection terminals are contacted with each other.

The present invention is to provide a card reader that can prevent the illegal acquisition of magnetic information recorded on a magnetic stripe, based on an output signal from a pre-head. More specifically described, in a card reader having a card insertion slot for guiding a magnetic card having a magnetic stripe to a transport passage and a pre-head arranged in the vicinity of the card insertion slot for detecting the presence of the magnetic stripe, the pre-head is equipped with a head portion having at least one pair of magnetic cores arranged to be opposite from each other having a magnetic gap between them and coils wound around a pair of the magnetic cores; and a signal different from that of the magnetic information recorded on the magnetic stripe is output from the pre-head.
