Patent attributes
An image formation apparatus or a sublimation printer includes a main frame, a platen roller, a head assembly, and a press lever. The platen roller is rotatably held between first and second side panels of the main frame. The press lever is pivotably supported on the first side panel of the main frame. The press lever presses the head portion against the platen roller with a predetermined pressing force when the press lever is pivoted. The first side panel has a groove that supports the press lever. The groove has a first wall portion on which the press lever abuts from a direction of the reaction force of the pressing force. The sublimation printer does not get deformed after repeated use, and therefore can generate the predetermined pressing force in a stable manner.
