It is. In order to display a visible image by heating, the thermal ink 2 must have characteristics as shown in FIG. 2 (To
can be repeatedly colored or made transparent by heating at room temperature (T2), maintaining that state at a certain temperature (temperature T1), and then returning to the original state by cooling (cooling temperature Ta).

本発明はこれらの欠点を解決するため構成に工夫をした
もので以下詳細に説明する。The present invention has a structure devised in order to solve these drawbacks, and will be described in detail below.

を用いて゛第４図の如き表示装置が構成される。FIG. 3 shows the basic structure of an embodiment of the present invention. In FIG. 3, 5 is a thin metal sheet such as stainless steel or copper, on which white paint 3 is applied, transparent thermo ink 2 is applied, and the surface is This is a structure covered with a protective film 1. A display device as shown in FIG. 4 is constructed using such a sheet.
第４図の６は上記の複合サーマルシートで、７はサーマ

ふきつけて冷却する。In Figure 4, 6 is the above-mentioned composite thermal sheet, 7 is a thermal head, and 8 is a heat-insulating material that keeps the display surface at a constant temperature, displays information on the front side, and blows cold air on the metal part on the back side on the way back. Cool.

冷却する。Fig. 5 shows the cross-sectional shape of a fixed blackboard-type display device, 6 is a blackboard-like structure by attaching a frame for strength to the above-mentioned composite thermal sheet, 8 is a heat-retaining insulation material, and 2 is movable horizontally or vertically. It is thermal ink. During normal writing, the heat insulating material 8 is brought into close contact with the back surface to keep it at a constant temperature, and during erasing, it is separated from the back surface and cooling air 9 is sent for short-term cooling.

運動させることによ多構成される。Figure 6 shows a configuration method for displaying in any color using the structure as described in 1. The figure (,) is a plan view;
Figure (b) is an enlarged view of the three primary colors, red, blue and green, using a transparent thermal ink on a thermal sheet and using a yellow base paint instead of a white base paint. It is constructed by printing four dots, aligning them with a thermal head, heating only the necessary dots, and moving them laterally while controlling the dots to become transparent as appropriate.
