Problems solved by technology

[0004] (2) The induction coil type read head is easily disturbed by the interference magnetic field except the magnetic field generated by the magnetic medium;
[0005] (3) The thickness of the induction coil read head is greater than or equal to 3.5 mm, which is not suitable for use in ultra-small and ultra-thin sales terminals;
[0006] (4) The material of the support frame of the induction coil type read head can only use magnetic materials, but not non-magnetic materials, resulting in higher production costs of the induction coil type read head

Abstract

The invention discloses a magnetic reading head for a point-of-sale terminal. The magnetic reading head comprises a support frame, a chip, a main frame and a spring plate; the support frame is arc-shaped, the support frame and the spring plate are respectively arranged on two sides of the main frame, a planar side of the support frame is fixedly connected with the corresponding side of the main frame, and the spring is in direct contact with the other side surface of the main frame; a groove is arranged in the middle of an arc surface of the support frame, the chip is disposed in the groove, and the plane with the chip is parallel to the bottom plate of the groove; and the chip comprises at least one electrical bridge, each bridge arm of each electrical bridge comprises at least one magneto-resistor element, and all the magneto-resistor elements in each electrical bridge are identical. Signals outputted by the magnetic reading head and magnetic media of the magnetic reading head are irrelevant to movement speed of the magnetic reading head. The magnetic reading head is not interfered by disturbing magnetic fields except for a magnetic field generated by the magnetic media. The thickness of the magnetic reading head is smaller than or equal to 2mm, and the magnetic reading head is quite suitable for small and thin point-of-sale terminals.

Description

technical field [0001] The invention relates to the technical field of magnetic heads, in particular to a read-out magnetic head used in sales terminals. Background technique [0002] Magnetic heads are widely used in daily life. In the prior art, the read head used in the sales terminal usually adopts the induction coil type read head, for example, most of the read heads in the card reader used to read the magnetic information in the bank card adopt the induction coil type read head . The induction coil read head has the following problems: [0003] (1) The output signal is related to the moving speed of the magnetic strip on the magnetic medium such as a bank card relative to the induction coil type read head. When the moving speed of the magnetic medium relative to the induction coil type read head is faster, the induction coil type read head The stronger the output signal of the magnetic head; [0004] (2) The induction coil type read head is easily disturbed by the ...
