Description

A kind of card reader

Technical field

The utility model relates to the card reader of ATM, particularly in card reader for reading the IC module for reading and writing of bank card information.

Background technology

Be provided with card reader in ATM, for reading the bank card information that client is inserted by card inserting mouth, be convenient to client and operate by prompting.At present, the card reader of ATM is mainly through Electromagnetic Drive, as shown in Figure 1, it comprises electromagnet 101, the output shaft 102 of electromagnet 101 is provided with the revolving part 103 that can rotate relative to output shaft 102, revolving part 103 bottom is connected with fixed block 104, contact spring 105 is set bottom fixed block 104, when there being bank card 106 to insert from card inserting mouth, when bank card moves to card reader position with gear train, sensor sensing is to bank card 106, then signal is sent to system, Systematical control electromagnet 101 runs, electromagnet 101 driven rotary part 103 rotates, thus revolving part 103 drives fixed block 104 to press down, be pressed on the chip of bank card 106 to make the contact spring 105 bottom fixed block 104, when the chip on contact spring 105 with bank card 106 is on time, then can read bank card information, if contact spring 105 is not aimed at bank card 106 chip, then bank card information cannot be read, then Systematical control electromagnet runs, electromagnet drives fixed block to reset by revolving part, bank card is then exited by card inserting mouth by gear train, or recovery bank card, thus bring use constant to client, reduce the work efficiency of bank clerk, visible, current card reader needs gear train to coordinate with sensor precisely, just bank card information can be read, its Card Reader ability is unstable.

Utility model content

The utility model aims to provide a kind of energy accurately and the stable card reader reading bank card information.

A kind of card reader described in the utility model, comprise IC module for reading and writing, described IC module for reading and writing comprises installing plate, installing plate one end is provided with motor, the output shaft of motor is connected with gear train through installing plate, gear train is provided with cam, the edge that cam two is relative is respectively arranged with symmetrical extension block, installing plate below motor is fixed with rotating shaft, in rotating shaft, cover has the revolving part that can rotate to it, the first back-moving spring be connected with the two is provided with between revolving part with installing plate, travelling carriage is fixed with bottom revolving part, travelling carriage bottom be connected with can relative sliding frame do from high to low arching trajectory motion slide block, the second back-moving spring is provided with between slide block and travelling carriage, or be provided with the second back-moving spring between slide block and revolving part, slip front arranges crotch, slider bottom arranges contact spring, on Distance geometry bank card between contact spring with crotch, chip is equal with the distance of nearest minor face.

A kind of card reader described in the utility model, when bank card is inserted by ATM card inserting mouth by client, bank card is transferred the IC module for reading and writing place that mechanism is delivered to card reader, now, motor runs, drive output shaft rotation, thus drive gear train to run, gear train band moving cam rotates, U-shaped sensor is had above cam, when the major axis flange of cam is pressed on travelling carriage, U-shaped sensor sensing is to the extension block on cam wherein an edge, then by signal transmission to controller, it is out of service that controller controls motor, then cam stops operating, travelling carriage is in the lower pressure of cam, rotate with revolving part, simultaneously, first back-moving spring tension is extended, thus the slide block of travelling carriage bottom presses down, now, the minor face that on bank card, distance chip is nearest contacts with the crotch of slip front, the contact spring of slider bottom contacts with the chip on bank card, bank card continues to continue to move ahead with conveying mechanism, simultaneously, bank card band movable slider together moves ahead, slide block moves down along the eminence of the arching trajectory of travelling carriage, until when bank card and slide block together move to the position transducer place in card reader, position transducer senses bank card, by signal transmission to controller, thus Systematical control conveying mechanism is out of service, slide block and bank card stop motion simultaneously, now, the stressed stretching of second back-moving spring, contact spring is tightly pressed on bank card chip, card reader starts to read bank card information, when client's end of operation, when needing card taking, controller controls motor and runs, thus the output shaft of motor drives gear train to run, and then gear train band moving cam rotates, the remote spots of cam is caused to leave travelling carriage, now, travelling carriage is not stressed, under the reset response of the first back-moving spring, travelling carriage is lifted, and be with on movable slider and lift, thus contact spring and crotch leave bank card, when U-shaped sensor senses the extension block on another edge of cam again, by signal transmission to system, Systematical control motor is out of service, effectively prevent from motor from continuing band moving cam to rotate, simultaneously, bank card returns with conveying mechanism, spued by card inserting mouth, due to the crotch of slide block and contact spring not stressed, then slide block is back to original position along the arching trajectory of travelling carriage under the effect of the second back-moving spring, complete Card Reader operation.Because on the Distance geometry bank card between contact spring with crotch, chip is equal with the distance of nearest minor face, therefore, when bank card props up crotch on slide block and together after a mobile segment distance, can guarantee that contact spring is aimed at the chip on bank card completely, ensure that card reader accurately reads bank card information, avoid because card reader cannot read bank card information and card is spued, or card is gulped down, ensure that client operates smooth and easy, save the time needing manual maintenance because of ATM Card Reader fault, work efficiency is high.
