Abstract:
A method of marking a number to a work, comprising a step of reading out said number from a card on which said number is displayed by data read-out means a plurality of times, a step of inputting each of read-out data to an arithmetic control apparatus so as to judge whether each of the data coincides, a step of transmitting the data to marking means and returning a received data to the arithmetic control apparatus from the marking means so as to judge whether the transmitting data is good, and a step of controlling the marking means to stop a marking operation by the marking means in the case that the received data is not good;wherein the number marked by said marking means is read out by the marking read-out means, is transmitted to the arithmetic control apparatus or the computer, and is compared with the standard data so as to judge whether good or no good;wherein the judgment of whether good or no good performed by comparing with said standard data is performed by combining at least a marking accuracy and a pattern matching degree of a character; andwherein a judgment whether good or no good on the basis of said pattern matching degree is performed such that an indefinite area slightly larger than a read-out error is provided in a boundary portion of whether good or no good in a judgment standard, the number judged to belong to the indefinite area is again judged a plurality of times by a plurality of character patterns previously registered, and thereafter in the case of being judged to still belong to the indefinite area, the judgment by viewing is performed.
