Coin sorter

When setting normal coin discrimination data for discrimination data in a pay-phone, it is to set the respective normal coin discrimination data corresponding to respective coin denominations as relative data corresponding to normal coin discriminable range data in this public phone. At the same time, each correct coin discrimination data corresponding to a type of coin is used to correspond to the data relative to the correct coin discriminable range data for being set. For the discriminating part of each public phone, it can be deemed as the same data as each correct coin discrimination data for being set. In comparing with the conventional skill in which a plurality of types of coins, for example ten types of coins, are inserted one by one into one public phone to correctly set the discrimination data, the present invention is able to greatly reduce the operating procedure for setting.
