摘要： PURPOSE:To reduce the size and the weight and to enhance reliability in strength by a constitution wherein the fitting part of a holder on the side subjected to tensile force of a leaf spring, upon attraction of an armature to a permanent magnet, retracts farther to the holder side than the side subjected to compression force of the leaf spring. CONSTITUTION:End face 21A at side A of a holder 21 where the average stress of a leaf spring 19, produced upon attraction of an armature to a permanent magnet, is plus(tension) is retracted farther by an amount of Z to the holder 21 side than the end face 21B at side B where the average stress is minus (compression). Consequently, effective length at side A is longer than that at side B and the tensile stress decreases correspondingly. Since imbalance between tensile stress and compression stress is eliminated at side B, no margin of strength is required at side B and thereby the leaf spring 19 can be reduced in size and weight resulting in the reduction of the size and the weight of the print head. When there is no dimensional restriction, reliability in strength is enhanced.

摘要： PURPOSE:To attain uniform density as the result of printing even when a round platen is used, by a method wherein an impact force of wires arranged in the fore end of a printing head is made strong sequentially from the center to the ends of an array of the wires by adjustment of a spring or adjustment of a cancel time of a magnetic force by an electromagnetic coil. CONSTITUTION:When a current flows through a coil 2, a magnetic force by a magnet 1 is canceled, a strain energy stored in a spring 6 is released partially, an armature 5 is detached from a core 3 with a point S on a yoke 4 used as a fulcrum, and the fore end of a wire 10 projects from a fitting hole of a bearing 11 bonded to the fore end of a printing head nose part 7 and strikes paper 15 through the intermediary of an ink ribbon 16. Thereby an impact force Fimp is generated. The impact force Fimp can be varied by varied a tightening amount D of a screw 8 and adjusting a spring force F. On a flat platen 17, a screw 7 is tightened so that the impact force be increased sequentially toward end wires 10b with the impact force Fimp of a central wire 10a used as a basis. In a printer wherein a round platen 19 is used, the impact force Fimp of all the wires can be adjusted to be uniform substantially, a density difference is eliminated and thus excellent printing can be attained.
