ABSTRACT:
A slip, a method of automatic reading of the slip, and an apparatus used therefor comprising a slip with delineated thereon a control mark made up of line segments of different lengths sequentially arranged in a line for representing a kind of format, information marks spaced apart from the control mark, each thereof being made up of line segments of different sizes arranged sequentially in a line, for representing task data, and information marks spaced apart from the information marks representing numerical data consisting of regions where numerals are written in and regions where bar patterns are written in, a scanning device receiving the slip as input thereto and outputting image data therefrom, a file unit previously storing therein formats corresponding to control marks, criterion coordinates and criterion numerical values corresponding to information marks representing task data, and criterion coordinates corresponding to information marks representing numerical data, read only memories storing therein in advance image data of numerals 0-9 and image data of predetermined bar patterns corresponding to the numerals 0-9, and a central prcessing unit for specifying the kind of the slip by comparing the image data with data from the file unit, deciding whether or not following data should be taken in, and comparing the image data with image data from the read only memories thereby to recognize numerals written in the information marks representing the numerical data.
