Claims

[Scope of utility model registration request]

(1) A plurality of tongues extending radially toward the center have a leaf spring to which an armature having a dot pin is fixed, respectively, and the tongues are biased by the magnetic force of a permanent magnet, and the tongues are biased by the magnetic force of a permanent magnet. In the spring-charged dot print head, the magnetic flux of the permanent magnet is canceled out by selectively exciting an electromagnet provided corresponding to the dot pin, and printing is performed using strain energy accumulated by a leaf spring as printing energy. A second electromagnet disposed on the outer periphery of the electromagnet facing the electromagnet, and a second tongue having a second armature at its tip facing the core of the second electromagnet. dot print head.

(2) The dot print head as set forth in claim 1, which is a registered utility model, characterized in that two excitation coils are driven so that the two tongues operate in opposition to each other (attraction and release).
