SPECIAL ORIGINAL DECIDING METHOD, COMPUTER READABLE STORAGE MEDIUM STORING EXECUTION PROGRAM OF THE METHOD, AND SPECIAL ORIGINAL DECIDING DEVICE

摘要

PROBLEM TO BE SOLVED: To decide whether an original is equal to the special one such as the paper money, securities, etc., where the metallic fibers are woven by measuring the magnetic level of the original after magnetizing it and then deciding whether the metallic fibers are woven into the original. SOLUTION: An original magnetizing part 71 magnetizes an original, and a magnetic sensor 72 measures the magnetic level of the magnetized original and stores the measured magnetic level in a magnetic level memory 73. A special original deciding part 75 reads the magnetic level out of the memory 73 and also reads the deciding threshold out of a deciding threshold memory 74 to decide whether the magnetic level exceeds the threshold. If the magnetic level exceeds the threshold, it's decided that the metallic fibers are woven into the original. Thus, a control part 77 decides that the original is equal to the special one such as the paper money, securities, etc., where the metallic fibers are woven. Then the part 77 instructs an original demagnetizing part 76 to demagnetize the original.
