Shielding protection device for magnetic head of card reader

Abstract

The invention discloses a shielding protection device for a magnetic head of a card reader. The shielding protection device comprises a card reader body, wherein an operation button is arranged on a front surface of the card reader body, a display screen is arranged at the top of the front surface of the card reader body, the display screen is arranged at the top of the operation button, a card reading region is arranged at the top of the card reader body, a card reading insertion hole is formed in the top of the card reading region, fixed blocks are arranged at two sides of the card reading insertion hole, sliding grooves are formed in the fixed blocks, and sliding blocks are connected with inner cavities of the sliding grooves in a sliding way. By application of the fixed block, the sliding grooves, the sliding blocks, a connection block, an electroplating metal shielding layer, a metal core layer, an outer insulation layer, a carbon steel wear-resistant layer and a moving groove ina matching way, and the problem that a traditional card reader is not provided with the protection device for shielding of the magnetic head so that a magnetic card cannot be rapidly identified by thecard reading machine is solved; and the magnetic head of the card reader has the advantage of magnetic head shielding protection device, and the identification speed of the card reader is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic head shielding of a card reader, in particular to a shielding protection device for a magnetic head of a card reader. Background technique [0002] The credit card machine is also called the POS machine. It is a multi-functional terminal. It is installed in the special merchants and acceptance outlets of the credit card and connected with the computer to form a network, so that the automatic transfer of electronic funds can be realized. It supports consumption, pre-authorization, and balance. Functions such as inquiries and transfers are safe, fast and reliable to use. [0003] When the credit card machine is working, it is necessary to use the magnetic head shielding protection device to anti-interference the magnetic head to achieve the recognition accuracy of the magnetic head. However, the traditional card reader does not have a protective device for magnetic head shielding, so that the card ...
