Abstract
PURPOSE: To secure the cancel of the mark with no use of the eraser or the like, by putting the marks at the upper and lower margins of the mark entry part on the memory medium.
CONSTITUTION: The mark is put into the mark entry part painted out with horizontal thick line, and that with vertical thick line put among the mark entry parts painted out with horizontal thick lines shows the mark entry part where the mark is cancelled. Horizontal parity check mark PCM is added to the mark entry part of the 8th row, but the PCM's of the 2nd, 3rd, 6th and 7th lines of the 8th row are cancelled in accordance with correction (cancel) of the data mark. And the PCM after correction is put into the 3rd and 7th lines of the 9th row. The mark reader usually reads in the PCM from each mark entry part of the 8th row, but reads out the PCM after correction from the mark entry part of the 9th row for the cancelled PCM
