Claims

[Claims for Utility Model Registration] A plurality of permanent magnets 11 arranged side by side with different magnetic poles facing each other with a predetermined gap between them, and the permanent magnet 1 loosely inserted into the gap and facing each other.
a moving coil 12 that moves in a direction perpendicular to the magnetic field formed by the moving coil 12 when excited, and a moving coil 12 that holds the moving coil 12;
A printing head characterized in that it has a coil base 18 made of a synthetic resin material whose other end is rotatably supported so that the dot pin 9 can be projected at one end against the bias of a spring means 17.
