Coin recognizing device and coin recognizing method

A coin recognizing device for recognizing a coin based on whether data of a plurality of recognition elements of the coin according to sensor outputs are included in predetermined value ranges, respectively, the coin recognizing device comprising:

• a main-judgment-frame registration unit for registering a main judgment frame for each denomination including the value ranges that are corrected so that the value range corresponding to at least one of the recognition elements does not overlap with the value range corresponding to the same recognition element of any other denominations;
• a reject-judgment-frame registration unit for registering a reject judgment frame for a specific denomination including the value ranges of the recognition elements of a coin of which data falls within the main judgment frame for the specific denomination but that is not to be judged as that of the specific denomination;
• and
• a judging unit for judging a coin of which data falls within the main judgment frame and does not fall within the reject judgment frame as a coin of a denomination corresponding to the main judgment frame.

• a main-judgment-frame registration unit for registering a main judgment frame for each denomination including the value ranges that are corrected so that the value range corresponding to a distribution of data of at least one of the recognition elements does not overlap with the value range corresponding to that of the same recognition element of any other denominations;
• an auxiliary-judgment-frame registration unit for registering an auxiliary judgment frame for a specific denomination including the value ranges of the recognition elements for a coin of which data does not fall within the main judgment frame for the specific denomination but that is to be judged as a coin of the specific denomination;
• a reject-judgment-frame registration unit for registering a reject judgment frame for the specific denomination including the value ranges of the recognition elements for a coin of which data falls within the main judgment frame for the specific denomination or the auxiliary judgment frame for the specific denomination but that is not to be judged as a coin of the specific denomination;
• and
• a judging unit for judging a coin of which data falls within either the main judgment frame or the auxiliary judgment frame and does not fall within the reject judgment frame as a coin of a denomination corresponding to the main judgment frame.
