. . . are provided in a number equal to the number of printing wires 6 . . . (12 in this example). A driving hammer 10 is attached to the intermediate portion of each arm 9a. Drive hammer 10
The tip of the arm 9a extends closer to the center than the tip of the arm 9a, and the rear end is located in the middle of the arm 9a.
They overlap from the middle part to the tip of a. The tip of the arm 9a is spot welded to the drive hammer 10 to increase its rigidity. A movable yoke 11 is attached to the middle part of the arm 9a, and in this example, the movable yoke 11 passes through the overlapping driving hammer 10 and the arm 9a.
1 is connected by caulking. The end surface of each marking pin 6a of the printing element 6 is brought into elastic contact with the front surface of the tip of the driving hammer 10 by the spring force of the return spring 7. The movable yoke 11 is driven by an electromagnet device 13, which will be described later.

極めて小さいものとなる。The movable yoke 11 is normally attracted by an electromagnetic device 13, which will be described later, and the spring section outward from the middle section of the arm 9a is flexibly bent and displaced rearward, and the tip of the drive hammer 10 is in the retreated position. For this reason, the printing wire 6 is retracted by the return spring 7, and its tip does not protrude from the head frame 1. During printing, the magnetic field that had been attracting the movable yoke 11 is canceled out, so that the movable yoke 11 becomes free and moves forward by the spring force of the drive spring 9. Since the arm 9a overlaps with the drive hammer 10 from the middle part to the tip, its rigidity is increased, so the forward force of the arm 9a is reliably transmitted to the drive hammer 10, and the tip of the drive hammer 10 moves forward, and the printing wire Advance 6. When the arm 9a moves forward, the arm 9a gradually comes into contact with the stopper plate 8 from its outer periphery toward the distal end, and its return is stopped when the engagement surface 9b finally comes into contact with the stopper piece 8a. When two members that are separated from each other momentarily collide and stop, a loud impact sound is emitted at the time of stopping, but this occurs because the contact area gradually increases continuously from the outer periphery of the arm 9a. The impact noise is extremely small.
