A thermal activating device of a thermal activation sheet having at least activation heating means (for example, the thermal head 40 and the heater element H) for heating and activating a thermal activator layer of the thermal activation sheet (for example, the heat sensitive adhesive label R) with the thermal activator layer (for example, the thermal activator layer K) formed at lease on one surface of a sheet-shaped substrate (for example, the base paper 500), forwarding means (platen roller 41 for thermal activation and the like) for forwarding the thermal activation sheet in a predetermined direction, and pushing means for pushing the thermal activation sheet toward the activation heating means, which is designed to comprise thermal activation sheet detecting means (heat sensitive adhesive label detecting sensor S1) for detecting a presence of the thermal activation sheet at a predetermined position, and pressure releasing means (a controller 1500, a cam mechanism 60, and a working mallet member 50) for releasing a pressure working between the pushing means and the activation heating means when judging that the thermal activation sheet does not exist at the predetermined position according to the detection result of the thermal activation sheet detecting means.

1. Field of the Invention
The present invention relates to a thermal activating device of a thermal activation sheet with a thermal activator layer for developing color and adhesion by heating formed on at least one surface thereof and a printer by using the thermal activating device, and more particularly to a technique of preventing a heat sensitive adhesive and a metamorphic material of the heat sensitive adhesive from attaching to the thermal activation sheet.
2. Description of the Related Art
For a more better understanding of the present invention, reference is made of a detailed description to be read in conjunction with the accompanying drawings, in which:
FIG. 1 is a schematic view showing the structure of a thermal printer according to the invention;
FIG. 2 is a block diagram showing the structure of a controller of the thermal printer;
Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing the structure of a thermal printer according to the invention, and FIG. 2 is a control block diagram of the thermal printer. In FIG. 1, the reference mark P1 indicates a thermal printer unit, the reference mark C1 indicates a cutter unit, the reference mark A1 indicates a thermal activating unit as a thermal activating device, and the reference mark R indicates a heat sensitive adhesive label as the thermal activation sheet reeled like a roll.
The thermal printer unit P1 has the general structure comprising a printing thermal head 10, a platen roller 11 pushed toward the printing thermal head 10, and a driving system (for example, a first stepping motor M1, a gear series, and the like), not illustrated, for rotating the platen roller 11.
