Abstract

PURPOSE:To perform printing with a rectangular matrix easy to see by a method wherein, by inclining a projection at a hammer at a fixed angle to the direction vertical to a linear projection whereby the inclination of a dot matrix caused by the move of printing paper when the printing paper is moved at a fixed speed is eliminated. CONSTITUTION:A linear element body 1 having the plural number of linear projections 2, 2... formed in parallel with each other is made to run in the direction of an arrow A at a fixed speed, while printing paper 6 is made to run in the direction B also at a fixed speed. Simultaneously with the coming of one 2a of the projections of the linear element body 1 to the left end of one 4a of the projections of a hammer 3, a dot 10 is formed on the printing paper 6 by actuating a corresponding driving device 5, and, after that, until the linear projection 2a moves to the right end of the projection 4a, the printing of the 1st line of one character is completed by driving the hammer 3 at a fixed timing. The tip 4a of the hammer 3 is inclined to the horizontal direction, and the printing of one line is made to be horizontal by properly regulating the running speed of the printing paper 6 and the angle alpha of the above inclination.
