It is provided with a pressure roller 34 for the purpose.

That is, since information such as the issuer and the amount of money is printed as magnetic ink on the banknote p such as a check from the beginning, the magnetic ink character information is recognized and obtained through the MICR device 30. will be.

Therefore, the banknotes p introduced from the outside through the inlet 10 are continuously conveyed by contacting and rubbing the conveying rollers 24 which are provided at predetermined intervals along the conveying path 21 and rotated. After passing through the magnetic recognition head 32 side from the front end thereof, the conveying rollers 24 are continuously conveyed.

However, the magnetization component contained in the magnetic ink letter on the banknote p is gradually dropped with the use of the banknote p, and the degree of magnetization thereof is lowered, and the degree of magnetization of the magnetization component is deteriorated with time. Therefore, the degree of magnetization of the magnetic ink character on the banknote p that has been used many times or has been deteriorated for a long time is very low, so that the MICR device 30 does not recognize the magnetic ink character information during the processing, and the recognition error is reduced. By being generated, the operation reliability of the device is reduced.

Therefore, in order to solve this problem, the recognition result signal from the magnetic recognition head 32 may be amplified to improve the recognition rate. However, according to this method, the noise is also increased according to the signal amplification. There was a problem that a recognition error occurred.

The present invention was devised to solve the above problems, and provided with a magnet amplifying means on the front side of the magnetic recognition head to increase the degree of magnetization of the magnetic ink on the bill passing, and then the magnetic ink character It is an object of the present invention to provide a magnetic ink character recognition device of an automatic bill processor for recognizing a letter more accurately in a magnetic recognition head.

Magnetic ink character recognition device of the automatic banknotes processing apparatus of the present invention for achieving the above object is obtained by recognizing the magnetic ink character information described on the banknote to be inserted and then transferred along the conveying path as a magnetic recognition head A magnetic ink character recognition device of an automatic bill processor for bills, wherein the magnetization degree of the magnetization component contained in the bill-shaped magnetic ink letters that are provided on the conveyance path in front of the entry side of the magnetic recognition head is temporarily It characterized in that it comprises a magnetizing amplification means to be amplified by.
