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

First, referring to FIGS. 3, 4 and 5, a reversible thermosensitive recording sheet (hereinafter simply referred to as a reversible sheet) 101 disclosed as a thermochromic in, for example, Japanese Patent Laid-Open No. 63-39377. The configuration will be described. FIG. 3 is a cross-sectional view of the reversible sheet 101, in which the recording layer 103 is formed on the transparent polyester film 102,
An overcoat layer 105 is provided to protect the film. The recording layer 103 is made of an organic low molecular weight substance 10 in the resin.
4 is in a dispersed state.

Next, referring to FIG. 4, the reversible sheet 10
The white turbid state and the transparent state of No. 1 will be described. In the state on the left side of FIG. 4, the organic low molecular weight substance 1 in the reversible sheet 101 is
Since the particles of No. 04 are composed of a relatively large single crystal, the light incident on the reversible sheet 101 rarely passes through the interface of the crystals, the light is transmitted without being scattered, and it looks transparent as a whole. .. In the state on the right side of FIG. 4, since the particles of the organic low molecular weight substance 104 in the reversible sheet 101 are made of polycrystal, the light incident on the reversible sheet 101 is refracted and scattered many times at the crystal interface. However, it looks cloudy as a whole.

Further, the thermoreversible property of the reversible sheet 101 will be described with reference to FIG. First, the reversible sheet 101
However, when it is in a cloudy state at room temperature, when it is heated, the transmittance starts to increase 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, the transparent reversible sheet 10 is used.
When 1 is reheated to the temperature D 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 because the organic low molecular weight substance 104 is melted at the temperature D or higher and the polycrystal is deposited in the process of cooling to the normal temperature. The temperature A is about 50 degrees and the temperature B is 5.
The temperature is 6 to 68 degrees and the temperature D is about 72 degrees. An image forming means for recording on the reversible sheet 101 is a thermal head 19.
Therefore, by changing the energy applied to one pixel determined by the resolution of the thermal head 19, the transparent state and the cloudy state can be set for each pixel.

The transparent polyester film 10
The colored layer 106 is disposed below the reversible sheet 101.
The contrast of the image recorded in is emphasized. That is, the reversible sheet 101 is used to highlight an image due to a difference in color between the transparent portion and the cloudy portion.
When the color of 06 is black, the entire reversible sheet 101 is made cloudy, and only the image portion is made transparent, the image appears black on a white background from the display surface. The reverse is also possible, and it is clear that the same effect can be obtained by changing the color of the colored layer 106 to another color such as red, blue, and green.

An example of the stamp document creating operation of the stamp device 80 of this embodiment will be described below with reference to the flowchart shown in FIG.

First, when the power is turned on, step S1
(Hereinafter, simply represented by S1. The same applies to other steps.) Initialization of each buffer / register in the RAM 66 and other initialization are performed. Display 14
A character string is input with the keyboard 10 while confirming the character input with. The thermal perforation data input by the character key 42 is stored in the input buffer 73 through S2, S3, and S4, and the character corresponding to the thermal perforation data is displayed on the display 14 through the display CG-ROM 69 in S5. To be done.

Next, the edited image is recorded on the reversible sheet 10.
When the confirmation key is pressed in order to confirm by using 1, the reversible sheet 101 stored in the reversible sheet holding portion 15b is pulled out by the reversible sheet pull-out roller 21b, and by the stencil sheet feed roller pair 22.

The reversible sheet 1 discharged from the discharge port 92
If the heat-recorded image is satisfied at 01, then a stencil sheet 24 for printing is prepared. When the original creation key is pressed, the stencil sheet withdrawing roller 21a is driven to pull out the stencil sheet 24 from the stencil sheet holding section 15a, and then it is conveyed by the stencil sheet feed roller pair 22. The subsequent operation is the same as in the conventional example. Therefore, the description is omitted.

If the image thermally recorded on the reversible sheet 101 is unsatisfactory, first, the image thermally recorded on the reversible sheet 101 is erased. When the reversible sheet 101 is supplied to the transport guide 86 and the erase key is pressed (S12), S
