Abstract

PURPOSE:To easily perform error detection of high accuracy by subjecting the numbers of every bit row or line of inputted data to prescribed operations and comparing the results with the check codes of every bit row and line added to the input data. CONSTITUTION:The number of 1 or 0 is beforehand added to every bit row or line via a CPU5 to the binary data of the prescribed bit numbers inputted, and the results thereof are divided by >=3 integers, and the remainder of the results of said division are beforehand added as binary check codes to every bit row or line. When data are inputted through a card reader 2, the number of 1 or 0 for every bit row or line is added thereto via the CPU5, and the results thereof are divided by >=3 integers and the remainder of the results of said division and the check codes of every bit row or line added to the input data are compared, whereby the errors of the inputted data are detected. By such method, the error detection of high accuracy is accomplished easily without requiring intricate checkings.
