PURPOSE:To detect a printed line without fail and to prevent the accident of double printing by printing and reading mark for printed line detection in the different positions of preceding and following pages. CONSTITUTION:The full black marks for printed line detection are printed in the column of lines or out of the column of the reminder so as to be different ly positioned in the preceding and following pages. When this full black mark is printed, the black part widely falls down because of the mark with wide width and stablized rather than the case of character detection (the parts of dot lines) and accordingly, the condition of n=m [(n) is the black part and (m) is unprinted part] is established and it can be decided that the line is printed. Then, all the full black marks can be detected without fail. By varying the printing positions of the marks in the preceding and following pages, reading misses caused by back transmission can be prevented. Thus, the printed line can be detected without fail and further, the reading miss caused by the back transmission is not generated.
