Numerical controller

Abstract

Abstract PURPOSE:To judge abnormality accurately by comparing the number of data stored on a command tape with the number of data which are stored in a memory and correspond to comment parts. CONSTITUTION:The memory 100 is stored with data corresponding to the 1st code read by a tape reader 101, and a code converting means 102 generates a command tape of the 2nd code on the basis of said data. When this command tape is read, a detecting means 103 detects comment parts of this tape. A collating means 104 collates the command tape with the data stored in the memory 100 on the basis of the detection result. In this case, characters stored on the command tape are collated with the internal codes in the memory 100, one by one, and the numbers of characters stored in both comment parts of the command tape and memory 100 are compared with each other. Consequently, a collation error is prevented from occurring at a character part which is not present as an EIA code.
