Abstract
A thermal transfer recording apparatus for carrying out recording by driving a thermal head to transfer ink of an ink film in transportation. This apparatus includes a separating device disposed downstream of the thermal head with respect to a direction of ink film movement and spaced from a platen roller. The separating device has an uneven surface.
Claims16
A thermal transfer recording apparatus comprising:
- a thermal head including a plurality of heating elements arranged in a row;
- a platen roller for transporting recording paper to a position opposed to said thermal head;
- ink film transport means including a supply reel for supplying an ink film and a takeup reel for taking up the ink film, said ink film transport means transporting the ink film, synchronously with recording paper transportation, to a recording section where said thermal head and said platen roller are opposed to each other;
- and
- an idle roller slightly spaced from a peripheral surface of said platen roller for contacting a back face of the ink film between said recording section and said takeup reel, said idle roller rotatable with movement of the ink film, and said idle roller including grooves in a grid form on a peripheral surface thereof.
