Abstract (en)
[origin: EP0431876A2] A printer head consists of a yoke (11), magnet members (12) mounted to the yoke, a base plate (14) attached to the front of the yoke (11), and a plurality of head pins (17) provided between the yoke (11) and the base plate (14). In this printer head, the head pins (17) are arranged in straight rows, which are inclined at a specified angle to the direction of stroke of the printer head. The base plate (14) is formed with a plurality of through- holes (18) at positions corresponding to the head pins so that the head pins can be advanced and retracted through the through-holes (18) by the action of the magnet circuit. <IMAGE>
