Movable coil type printing head

Abstract

Abstract PURPOSE: To improve responsibility, reliability of operations and durability by a method wherein by a printing lever penetrating a central yoke and members regulating its deflective deformation installed, the printing lever is not deformed and printing operations are made stable even when a large printing force is given. CONSTITUTION: A printing lever 9 is penetrated through a central yoke 31 which constitutes a magnetic flux generating means crossing a movable coil 28 and posseses the magnetic flux generating means, the movable coil 28 fixed at a printing lever 9 and the movable coil 9 having an end fixed and the other end provided with printing elements, and along with these, regulation members 35, 36 37 for regulating the deflective denaturation of the lever are installed. Directly after a printing hammer 15 collides with a projecting part 54, a deforming force to the left hand still works at the center of a lever 13 through inertia, however, the front end face of a holder 19 contacts with a nut 37, and a deflective deformation due to inertia is regulated. Accordingly, the printing lever receives no forced strength and returns to the rest position as shown in a figure with its own spring force. COPYRIGHT: (C)1981,JPO&Japio
