Card reader

Abstract

A card reader comprises an IC read-write module. The IC read-write module comprises a mounting plate, a motor is installed at one end of the mounting plate, and an output shaft of the motor penetrates through the mounting plate to be connected with a drive mechanism; a cam is installed on the drive mechanism, and symmetrical extension blocks are arranged on the two edges, opposite to each other, of the cam respectively; a rotating shaft is fixed on the portion, below the motor, of the mounting plate, a rotating part which can rotate relative to the rotating shaft is arranged on the rotating shaft in a sleeving mode, and a first reset spring which is connected with the rotating part and the mounting plate is arranged between the rotating part and the mounting plate; a sliding frame is fixed at the bottom of the rotating part, the lower portion of the sliding frame is connected with a sliding block which can do arc-shaped track movement from high to low relative to the sliding frame, and a second reset spring is arranged between the sliding block and the sliding frame, or the second reset spring is arranged between the sliding block and the rotating part; a hook is arranged at the front end of the sliding block, a contact spring is arranged at the bottom of the sliding block, and the distance between the contact spring and the hook is equal to that between an upper chip of a bank card and the nearest short edge of the bank card.

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
