PROBLEM TO BE SOLVED: To apply an invalidation marking on various kinds of security paper by a constitution wherein a moving section is moved between a rest position and an operation position in contact with incomplete security print at a prescribed angle with respect to a moving direction of a print carrier. SOLUTION: A linear motor 1 is provided to be fixed to a portion in the vicinity of a circumference of a cylinder 4 possessed by a printer. A marker 2 is fixed to a moving section 1a of the linear motor 1. The moving section 1a moves perpendicularly to a print carrier (sheet) 3. When it is judged that one of the printed results on the sheets 3 is a misprint by a print quality control system, a marking start signal is transmitted to the linear motor 1, then the linear motor 1 allows the moving section 1a having the marker 2 to press a position of the printed result on the sheet. Next, a marking completion signal is transmitted to the linear motor 1 to remove the marker 2 from the sheet 3. |
