Abstract

A thermal recording apparatus comprises a platen (3) a thermal head (2) for carrying out thermal recording by pressing a recording paper (4) onto the platen, a spring member (36) for pressing the thermal head (2) onto the platen (3) by the spring force, a displacing member (19) displacably provided while being in contact with the spring member (36) for changing the force of the spring member (36) by the displacement, selecting means having a plurality of printing process controlling data for selecting therefrom specific printing process for controlling data corresponding to the state of printing, and displacing amount controlling means for controlling the amount of displacement of displacing member in accordance with the specific printing process condition selected by the selecting means. The pressure of the thermal head (2) onto the recording paper (4) can be controlled corresponding to the conditions of printing and to the types of the recording paper (4) by the above described structure.
