Claims

[Claims for Utility Model Registration] (1) Setting direction detection means for detecting the setting direction of printing paper, and control for always keeping the position and orientation of characters with respect to the printing paper constant in accordance with the detection signal of this setting direction detection means A printing device characterized by having means. (2) A printing paper detection means that has a notch formed in a part of the rectangular printing paper and can detect the printing paper when the printing paper is set in the normal direction and when the printing paper is set in the opposite direction to the normal direction. When the printing paper is set from the normal direction, the printing paper is not detected at the notch position, and when the printing paper is set from the opposite direction to the normal direction, the printing paper is detected by the setting direction detection means. , the position and orientation of the characters relative to the printing paper when only the printing paper detection means detects the printing paper, and the position of the characters relative to the printing paper when both the printing paper detection means and the setting direction detection means detect the printing paper. and a control means for always keeping the direction constant. (3) A printing paper detection means that has a notch formed in a part of the rectangular printing paper and can detect the printing paper when the printing paper is set in the normal direction and when the printing paper is set in the opposite direction to the normal direction. When the printing paper is set from the normal direction, the printing paper is not detected at the notch position, and when the printing paper is set from the opposite direction to the normal direction, the printing paper is detected by the setting direction detection means. a first print head capable of printing characters in a predetermined position and orientation with respect to the print paper when the print paper is set from the normal direction; a second print head capable of printing characters in the predetermined position and orientation on the print paper when the print paper is detected; 1. A printing device comprising control means for operating a second print head when both the paper detection means and the set direction detection means detect printing paper.
