Problems solved by technology

When the conveying speed fluctuates, the length of the magnetic detection signal read by the magnetic head in the direction of the time axis will deviate. Therefore, there is a possibility that characters cannot be recognized in the standardized template.
In addition, in the

Example Embodiment

[0044] Hereinafter, embodiments of the magnetic ink character recognition device and program according to the present invention will be described in detail with reference to the accompanying drawings.

[0045] figure 1 It is a diagram showing a schematic configuration of a magnetic ink character recognition device. like figure 1As shown, the magnetic ink character recognition device 1 has a paper conveying path 11 , a conveying roller 12 , a magnetic head 13 and a platen 14 .

[0046] The paper conveyance path 11 is a conveyance path for conveying paper PA as a medium. The paper PA is a medium (single sheet) such as a check, a promissory note, and a magnetic ink character MC is printed on its surface (refer to figure 2 ).

[0047] figure 2 It is a figure which shows an example of paper PA. like figure 2 As shown, information such as the check number is printed on the surface of the paper PA as magnetic ink characters MC. The related magnetic ink characters MC are pr...

Abstract

A magnetic-ink-character recognizing device and a control method are disclosed for increase in the character recognition rate. The device includes a magnetic head, a conveying section configured to convey a medium on which magnetic ink characters are printed, an acquiring section configured to acquire a magnetism detection signal read by the magnetic head, a segmenting section configured to segment waveform data of the magnetic ink characters from the magnetism detection signal, a first calculating section configured to compare the waveform data segmented by the segmenting section and reference waveform data and calculate similarities of both the data, respectively, a second calculating section configured to compare the waveform data segmented by the segmenting section and extended waveform data obtained by compressing or expanding length in a time axis direction of the reference waveform data and calculate similarities of both the data, respectively, and to recognize the magnetic inkcharacters of the waveform data segmented by the segmenting section.

Description

[0001] This application claims the priority of the Japanese application with the filing date of December 08, 2017 and the application number JP2017-236283, and cites the content of the above-mentioned application, which is incorporated herein by reference in its entirety. technical field [0002] Embodiments of the present invention relate to a magnetic ink character recognition device and a control method. Background technique [0003] Currently, there are magnetic ink character recognition devices such as MICR (Magnetic Ink Character Reader: Magnetic Ink Character Reader) that read magnetic ink (ink) characters (letters) printed on paper using a magnetic head. For example, in the magnetic ink character recognition device of the paper conveyance type, the paper on which the magnetic ink characters are printed is read by a magnetic head while being conveyed, and the magnetic ink characters are recognized based on the magnetic detection signal (magnetic detection signal) outpu...
