Claims

[Scope of utility model registration request]

In a printing solenoid, the rear end of a needle is fixed to an armature that is supported so as to be able to swing elastically in the front and back direction, and the front end of a yoke that magnetically attracts this armature faces the back side of the armature. . A printing solenoid in which the front surface of the tip of the yoke is formed into an inclined surface at a predetermined angle with which the back surface of the armature comes into contact when the needle is retracted.
