a card reader

Abstract

A card reader, including an IC read-write module, the IC read-write module includes a mounting plate, a motor is installed at one end of the mounting plate, the output shaft of the motor passes through the mounting plate and is connected with a transmission mechanism, and a cam is installed on the transmission mechanism, and the cam The two opposite edges are respectively provided with symmetrical extension blocks, the mounting plate below the motor is fixed with a rotating shaft, the rotating shaft is covered with a rotating part that can rotate relative to it, and there is a connection between the rotating part and the mounting plate. The first return spring, the sliding frame is fixed on the bottom of the rotating part, the lower part of the sliding frame is connected with a slider that can move from high to low in an arc-shaped trajectory relative to the sliding frame, and a second return spring is arranged between the sliding block and the sliding frame. Or a second return spring is arranged between the slider and the rotating member, a hook is arranged at the front end of the slider, and a contact spring is arranged at the bottom of the slider, the distance between the contact spring and the hook and the distance between the chip on the bank card and the nearest short side The distance is equal.

Description

technical field [0001] The invention relates to a card reader of an ATM machine, in particular to an IC read-write module for reading bank card information in the card reader. Background technique [0002] There is a card reader inside the ATM, which is used to read the bank card information inserted by the customer through the card slot, so that the customer can operate according to the prompts. At present, the card reader of the ATM machine is mainly driven by electromagnetic force, such as figure 1 As shown, it includes an electromagnet 101, the output shaft 102 of the electromagnet 101 is provided with a rotating member 103 that can rotate relative to the output shaft 102, the bottom end of the rotating member 103 is connected with a fixed block 104, and the bottom of the fixed block 104 is provided with a contact spring 105 , when a bank card 106 is inserted from the card slot, and the bank card moves to the position of the card reader with the transmission mechanism, ...

Problems solved by technology

At present, the card reader of the ATM machine is mainly driven by electromagnetic force, such as figure 1 As shown, it includes an electromagnet 101, the output shaft 102 of the electromagnet 101 is provided with a rotating member 103 that can rotate relative to the output shaft 102, the bottom end of the rotating member 103 is connected with a fixed block 104, and the bottom of the fixed block 104 is provided with a contact spring 105 , when a bank card 106 is inserted from the card slot, and the bank card moves to the position of the card reader with the transmission mechanism, the sensor senses the bank card 106, and then sends a signal to the system, and the system controls the operation of the electromagnet 101, and the electromagnet 101 Drive the rotary part 103 to rotate, thereby the rotary part 103 drives the fixed block 104 to press down, so that the contact spring 105 at the bottom of the fixed block 104 is pressed on the chip of the bank card 106, when the contact spring 105 is aligned with the chip on the bank card 106 On time, the bank card information can be read. If the contact spring 105 is not aligned with the bank card 106 chip, the bank card information cannot be read. Then the system controls the operation of the electromagnet, and the electromagnet drives the fixed block to reset through the rotating part, and the transmission The institution withdraws the bank card from the card slot or recycles the bank card, so as to bring the same use to the customer and reduce the work efficiency of the bank staff. It can be seen that the current card reader needs the precise cooperation between the transmission mechanism and the sensor. The bank card information is read, and its card reading ability is unstable
