Claims

[Scope of utility model registration request]

(1) It is loosely fitted into the guide groove of the clapper guide plate with its position regulated, the printing needle is fixed to the free end, and the opposite base end is pressed by the clapper pressing spring supported by the stopper board to pivot. a plurality of clappers which are movably supported, have a movable core fixed to an intermediate portion, and are abutted against a stopper member by means of a return spring to normally hold the needle in a non-printing position; an electromagnetic coil; and a fixed core. an electromagnetic plunger which operates to attract the movable coil by means of a fixed iron core when the electromagnetic coil is energized, pivot the clapper against the action of a return spring, and move the needle to a printing operating position; 1 placed at both ends of the fixed iron core to form the magnetic circuit of the electromagnetic plunger
In a dot printer print head including a pair of yokes, an end of the fixed iron core opposite to the movable iron core is fixed to one of the yokes, and a plurality of positioning columns made of a magnetic material are fixed to one of the yokes. One end is planted respectively, and the other end of the positioning column Q is fitted with the other end of each of the yokes, the clapper guide plate, the clapper pressing spring, and the positioning hole provided in the stopper board, thereby positioning these members. A print head for a dot printer, characterized in that a magnetic circuit is formed between the pair of yokes.

(2) Utility model registration claim No. (2) in which an insulating sheet is interposed between the other yoke and the clapper guide plate.
The print head of the dot printer described in item 1).
