Abstract

The invention provides a magnetic image sensor. The magnetic image sensor includes: magnetic induction resistors, arranged along the scanning direction, used to detect changes in magnetic signals within the range to be detected; configured resistors, connected to the magnetic induction resistors, configured as resistors with adjustable resistance; drive circuits, connected to the magnetic induction resistors Resistor connection for output control of the signal detected by the magnetic induction resistor. The present invention solves the problem that the noise signal of the magnetic image sensor in the related art is relatively large due to the deviation of the magnetoresistance.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a magnetic image sensor. Background technique [0002] Making specific magnetic information on banknotes, bills, securities and other media is one of the important means of modern anti-counterfeiting technology, and with the development of production technology, the application of magnetic information anti-counterfeiting technology is also being continuously strengthened, such as in many countries High-end banknotes (such as RMB, US dollars, Euros, etc.) contain rich magnetic information inside. It is also an indispensable anti-counterfeiting detection method for the identification of specific magnetic information on paper money, bills, securities and other media. [0003] In order to realize the above-mentioned detection, a magnetic image sensor is provided in the related art. The magnetic image sensor continuously arranges small magnetic heads in the entire reading identification range ...
