Problems solved by technology

[0002] With the development of information technology and anti-counterfeiting technology, there are more and more magnetic information produced by magnetic ink printing technology contained in various bills and securities. The reading device reads bills and securities. As we know, the existing magnetic reading device can only simply determine the presence or absence of magnetism, or identify simple magnetic digital symbols (such as E13B fonts, etc.) by MICR, and This kind of recognition is distinguished by the different waveforms corr...

Embodiment Construction

[0016] The present invention will be described in detail below through specific examples and in conjunction with the accompanying drawings.

[0017] figure 1 It is a block diagram of the circuit principle of the magnetic image reading device of the present invention, including a control unit 1, a magnetic image sensor unit 2, a storage unit 3, a motor and transmission unit 4, a control panel 5, and an interface unit 6.

[0018] The control unit 1 is the main control chip of the reading device, responsible for host communication, generating the control signals required by each unit, receiving and processing the data from the magnetic image sensor, and then transmitting it to the host computer. The control unit 1 is compatible with the existing The technology is the same, so I won't repeat them here.

[0019] The magnetic image sensor unit 2 scans the magnetic image according to the control signal of the main control chip, and transmits the scanned signal to the main control un...

Abstract

The invention discloses a magnetic image reading device which is characterized in that a magnetic image sensor unit is a magnetic linear array sensor. The magnetic image sensor unit solves the defects of low data quantity and non-intuitive judgment since the existing monomer magnetic detection unit can only judge the existence of magnetism or identify simple magnetic numeric characters by means of MICR, and can not only identify magnetic data provided by standard magnetic characters as well as non-standard magnetic characters, but also identify various magnetic pictures. Therefore, such an identification method can have large identifiable data quantity and intuitive judgment and ensure that most of acquired data can be understood by people and are very convenient for use.

Description

technical field [0001] The invention relates to an image reading device, in particular to a magnetic image reading device. Background technique [0002] With the development of information technology and anti-counterfeiting technology, there are more and more magnetic information produced by magnetic ink printing technology contained in various bills and securities. The reading device reads bills and securities. As we know, the existing magnetic reading device can only simply determine the presence or absence of magnetism, or identify simple magnetic digital symbols (such as E13B fonts, etc.) by MICR, and This kind of recognition is distinguished by the different waveforms corresponding to the output of different characters in standard fonts. The recognition method is abstract and unintuitive, and it is not easy for people to understand and grasp. For non-standard fonts, or some information such as graphics cannot be recognized. Therefore, the existing magnetic reading devi...
