Claims

[Scope of utility model registration request]

In a thermal head support mechanism for a thermal printer comprising a swingable thermal head fixing plate supported on an axis parallel to the platen, and a thermal head fixed to the fixing plate and facing the platen, the middle part of the square cross section is provided. a support bracket that is attached to the thermal head fixing plate and configures a square cross-section space parallel to the platen into which the intermediate portion of the shaft is loosely inserted;
a first spring elastic body inserted between one surface of the shaft intermediate portion and the thermal head fixing plate; a second surface perpendicular to the one surface of the shaft intermediate portion and the support fitting; a second spring elastic body inserted between the two spring elastic bodies; and a first spring elastic body that is screwed onto the support fitting and presses the shaft intermediate portion against the first spring elastic body.
A thermal head support mechanism for a thermal printer, comprising: a push screw point, and a second push screw screwed into the support fitting and pressing the intermediate portion against the second spring elastic body.
