Abstract

PURPOSE:To expedite the start of action of a leaf spring in response to a driving pulse and attain the stability of action thereof by providing a frame whose shape allows the supporting point to move sequentially to its tip when the spring is displaced. CONSTITUTION:One end of print pin 1 is fixed together with leaf spring 2 to frame 5 by clamp plate 3 and fitting screw 4. On frame 5 is provided fitting part 5a whose shape allows the supporting point to move to the tip in correspondence to the displacement of leaf spring 2. When a driving pulse is impressed on release coil 6b of magnet 6, leaf spring 2 held so far by permanent magnet 6c moves in the direction of arrow 7 because the magnetic flux is extinguished, and accumulated energy of spring 2 causes print pin 1 to perform impact printing. That is, spring force B comes to show the same characteristic as the attraction characteristic C of magnet 6, the stated number of spring increasing along with the displacement of leaf spring 2, thus the start of action of leaf spring 2 is expedited.
