Claims

[Claims for Utility Model Registration] A plurality of printing wires 49 are connected to the respective operating members 4.
The wire dot printer has a plurality of electromagnets 18 consisting of a core 5, a yoke 20, and a coil 11 corresponding to each operating member 46, and performs a printing operation by selectively driving the electromagnets 18. In this wire head, the core 5 is connected to a coil bobbin 10 around which a coil 11 is wound.
The coil bobbin 10 has a core end face side flange 10 in order to determine the relative position in the rotational direction with respect to the core 5'.
A positioning notch 17 is provided on b, a pair of terminal pins 15 are provided on the core fixing side collar portion 10a, and a pair of terminal pins 15 are provided on the core fixing side flange 10a, and a pair of terminal pins 15 are provided on the core fixing side bottom portion of the yoke 20. is provided with a through hole 12 that corresponds to the terminal pin 15 and penetrates outward; and is supported on the outer surface of the yoke 20 opposite to the support surface on which the core 5 is supported, and that the through hole Connecting hole 1 corresponding to 12
4 is provided, and a terminal pin 15 of each coil is provided.
and a circuit board 7 having a signal line 8 connected to each other.
