An ink transfer printer comprises a thermal head that has an ink reservoir provided on a top surface of a housing and a film provided on a bottom surface of the housing. A space is formed by the film and the bottom surface. An ink passage is formed in the housing to communicate the ink reservoir with the space. Porous glaze is provided on the bottom surface to face the ink passage. Heating elements are provided on the porous glaze. The ink kept in the ink reservoir is supplied to the space through the ink passage and the porous glaze. The film has perforated pore , which are substantially closed to block the ink when the heating elements are not heated. When the heating elements are heated, the film is deformed to eject the ink through the pores.
La présente invention a pour objet une imprimante à transfert d'encre comportant une tête d'impression thermique dotée d'un réservoir monté à la partie supérieure d'un boîtier, une mince pellicule venant en contact avec la surface inférieure du boîtier en question. Un espace sépare la pellicule de la surface inférieure du boîtier. Un passage d'encre est formé dans le boîtier pour établir la communication entre le réservoir d'encre et l'espace en question. Une glaçure poreuse est appliquée à la surface inférieure en opposition avec le passage d'encre. La pellicule comporte une structure poreuse qui bloque le passage de l'encre lorsque non chauffée. Lorsque chauffée, la pellicule en question se déforme et permet le passage de l'encre à travers ses pores.
