PURPOSE:To miniaturize the titled device by arranging a printing surface properly, with the steps are provided to the yorks, the heights of the steps are made as same as the heights of the magnets, and the magnets are mounted to each upper and lower step respectively, and the movable pieces and the printing pieces are arranged through these magnets. CONSTITUTION:The movable pieces 9 are attracted and the printing pieces 10 are lowered and a printing is carried out when a current is flowed to the magnet 7. A certain clearance is provided between these movable pieces 9 and magnet 7, and the movable pieces 9 are returned to their original positions by the return springs when the flow of the current are set to OFF. The yokes 6 formed integrally with the two pairs of this unit member are arranged symmetrically, and a number of dot becomes 4 dots. In the condition of the members are laminated double the number of the dot becomes 8 dots. An increase and decrease of the number of the dots are made easy only by a variation of a casing to be arranged, and miniaturized printing head can be obtained. |
