Abstract
An image formation apparatus or a sublimation printer includes a main frame, a platen roller, a head assembly, and an extension spring diagonally attached to the head assembly and the main frame so as to bias the head assembly in a direction away from the platen roller and in an axial direction of the platen roller. The head assembly has an arm portion and a head portion. The head assembly is pivotably held between side panels of the main frame so as to be pressed against and moved away from the platen roller. The extension spring keeps the thermal head away from the platen roller when printing is not performed, and also aligns the thermal head in the axial direction of the platen roller. The number of components of the sublimation printer can be reduced.

An image formation apparatus, comprising:
- a main frame having side panels;
- a platen roller rotatably held between the side panels of the main frame;
- a head assembly having an arm portion and a head portion, the head assembly being pivotably held between the side panels of the main frame so as to be pressed against and moved away from the platen roller;
- and
- an elastic member diagonally attached to the head assembly and the main frame so as to bias the head assembly in a direction away from the platen roller and in an axial direction of the platen roller.
A sublimation printer, comprising:
- a main frame having side panels;
- a thermal head;
- a platen roller rotatably held between the side panels of the main frame;
- holding means for holding the thermal head so as to be pivotable between the side panels of the main frame such that the thermal head is pressed against and moved away from the platen roller;
- and
- biasing means for biasing the thermal head so as to move the thermal head away from the platen roller and to align the thermal head with the platen roller in an axial direction of the platen roller.
