DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, with reference to FIG. 7, the structure of the thermoreversible display sheet 101 disclosed in Japanese Patent Laid-Open No. 63-39377 as a thermochromic will be described. FIG. 7 is a cross-sectional view of the thermoreversible display sheet 101. A recording layer 103 is provided on a transparent polyester film 102, and an overcoat layer 105 is provided to protect the recording layer 103.

In the state on the left side, since the particles of the organic low molecular weight substance 104 in the thermoreversible display sheet 101 are composed of a relatively large single crystal, light incident on the thermoreversible display sheet 101 passes through the crystal interface. The number of times is small, light passes through without being scattered, and it looks transparent as a whole. In the state on the right side of FIG. 8, the organic low molecular weight substance 1 in the thermoreversible display sheet 101 is
Since the particles of No. 04 are composed of polycrystal, the light incident on the thermoreversible display sheet 101 is refracted and scattered many times at the crystal interface, and appears as a white turbidity as a whole.

The thermoreversible characteristic of the thermoreversible display sheet 101 will be described with reference to FIG. First, when the thermoreversible display sheet 101 is in a cloudy state at room temperature, when it is heated, the transmittance starts to rise from the temperature A and reaches the maximum transparent state at the temperature B. And even if it is cooled to room temperature, the transparent state is maintained. This is because the organic low molecular weight substance 104 changes from a cloudy state polycrystal to a semi-molten state in the process of increasing from the temperature A to the temperature B, and a crystal grows to a transparent single crystal when cooled to room temperature again. This is because. Next, when the thermoreversible display sheet 101 in the transparent state is reheated to the temperature C or higher, it becomes an intermediate state between the maximum transparent state and the maximum cloudy state.
When it is cooled to room temperature, it returns to the original cloudy state. this is,
This is because the organic low molecular weight substance 104 is melted at a temperature of C or higher and a polycrystal is deposited in the process of cooling to room temperature. The temperature A is about 50 degrees, the temperature B is 56 to 68 degrees, and the temperature C is about 72 degrees. The image forming means for recording on the thermoreversible display sheet 101 is the thermal head 24, and the transparent state and the cloudy state can be set for each pixel by changing the energy applied to one pixel determined by the resolution of the thermal head. it can.
