Claims

[Scope of utility model registration request]

(1) In a serial printer in which the rotation of the type wheel shaft is selectively stopped to print the type and carried to the next position, a type wheel shaft having a plurality of type characters on the outer periphery;
a type wheel shaft that pivotally supports the type wheel and guides the type wheel in the axial direction; a selection gear having a ratchet corresponding to the type and fixed to one end of the type wheel shaft; and adjacent to the selection gear. a switching cam arranged as a cam and having a notch portion and a cam portion on its outer periphery; a selection pawl that alternately engages the notch portion of the switching cam and a ratchet portion of the selection gear; and a selection pawl that holds the selection pawl. a pawl shaft; a selection electromagnet that operates the selection pawl in a selective manner; and when the switching cam and the selection pawl are engaged, the selection gear is rotated for a character selection process; and a switching means that rotates the switching cam during a printing process, and in the printing process, by engaging the switching cam and the selection pawl, the selection pawl is pushed around and the selection gear and A printing device characterized in that a forcing force is applied to a retaining portion of the selection claw.

(2) The printing device according to claim 1, wherein the selection claw shaft holding the selection claw has a spring property.
