About MR sensor

Use for MR sensor


Fig.1
Reading of the magnetic pattern of the bill

The most useful use of the MR sensor is reading of the magnetic pattern.
Magnetic printing is to print it in ink which magnetic powder was combined with. The bill of each country of the world is one of the familiar things in the magnetic printing.
But, there are a few magnetic bodies contained in the magnetic printing very much. Therefore, a bill never sticks to the magnet 1000 yen. Generally that existence isn't known.
Do you know how a MR sensor reacts with the magnetic printing and it is detected? The character which shows it in the above is the example of the character made for the information processing.
This character was prescribed by JIS X9002. (Type E13B)
JIS X9002 is the standard of "the typeface for reading of the character for the magnetic ink and the specifications of the printing". A signal like a photograph of the Fig. 2 appears in the output terminal of the MR sensor when the E13B pattern character that magnetism was printed with this standard is passed through the detection side of the MR sensor.

Fig.3
A MR sensor is detected clearly though there are a few magnetic changes very much.
A used circuit diagram is shown in the Fig. 3. Furthermore, the example which is easy to understand is shown.

 

The magnetic pattern of the bill


Fig.4

Next, let's observe a bill with a MR sensor. The 1$ bill of the United States is used.
All magnetic patterns can't be shown to everyone. Therefore, a real photograph (left) and the image of the magnetic pattern(right) are divided with a diagonal. You will be able to recognize that the signal which is the same as the pattern being printed is detected. A MR sensor is used in the machine which handles a bill such as a vending machine, and the truth of the bill is judged from that signal.
