Claims

[Scope of utility model registration request]

A taper pin and first and second legs whose center axes are substantially parallel to each other are connected at the bottom to form a U-shape,
A hole is provided in the vicinity of the inner bottom surface on a surface perpendicular to the inner bottom surface in a direction substantially perpendicular to a plane containing the central axes of the first and second legs, and the taper pin is press-fitted into the hole. a base portion whose inner bottom surface is pushed up a predetermined distance; a first connecting portion having one end surface fixed to a central portion of the inner bottom surface of the base portion and the other end surface facing the one end surface; a columnar piezoelectric element whose one end face in the longitudinal direction is in contact with the other end face of the first connection part; and a second connection part in the form of a flexible flat plate whose one end is connected to the tip of the first leg part. and,
A third connection part having a flexible flat plate shape having one end connected to the tip of the second leg, and one end face contacting the other end face in the longitudinal direction of the piezoelectric element to the center of the piezoelectric element. a fourth connecting part arranged so that its axis is substantially parallel to the central axes of the first and second leg parts;
The piezoelectric element is connected to the other ends of the second and third connecting parts and the other end face of the fourth connecting part, and the elongation displacement caused in the longitudinal direction by applying a voltage to the piezoelectric element is expanded. and a printing wire whose one end is fixed to the other end of the lever mechanism, and which prints on a recording paper facing the other end by applying a displacement to the other end. printing element.
