Move the top surface of the machine in the left-right and front-back directions.

The base 1 is placed on the original so that the 1M original S fits within the frame of the original holding part 1c, and the original is supported.

Then, the copying machine main body 10 is lifted up from above the base 1 around the connecting part 25 to open the recording paper mounting section, and the thermosensitive coloring paper is placed on the weak adhesive layer 16 of the opened recording paper mounting section 1a. The recording paper 4 is supported and fixed.

The optical information formed on the light-receiving element 37 is converted into an electrical signal by the light-receiving element 37 and the image processing bag [38], and is applied to the writing head 39, where information corresponding to the image information of the original S is printed on the recording paper. is heated and colored, and when the reading section 11 reaches the left and right edges of the document S as shown by the third development dot-dashed line, the writing section 13 also reaches the left edge of the recording paper 14 and copies in the main scanning direction. finish.

- times of scanning in the main scanning direction, the copying machine body 10 is shifted by the effective width of the writing head by moving the desired range of the document, and the copying machine body 10 is moved rightward from that position. If you want to copy the entire document, you can repeat this operation repeatedly.

In the above embodiment, the case is shown in which the substrate is placed on top of a sheet-like original to make a copy. However, when copying from a thick original such as a single sheet, the substrate is placed on top of the thick original. All that is required is to position the document portion on the presser foot and scan the copying machine main body from above.

Furthermore, although the above embodiments used thermosensitive coloring paper as the recording paper, it is also possible to thermally transfer the image to commercially available paper via thermal transfer paper in one apparatus. In this case, thermal transfer paper and plain paper are mounted and fixed in a stacked state on the recording paper mounting section 1a. It is also possible to copy color originals. In this case, color separation filters 50 for each color are built into the optical system of the copying machine main body 10, and copying is performed by combining these with thermal transfer paper for each color (see FIG. 4). When copying a color original, the original and the thermal transfer paper are copied in a stationary state, so even if multiple images are created, high-quality color copies can be obtained without color shift.

Note that the thermal transfer paper used must be changed depending on the color of the filter used, but in order to display externally the color of the thermal transfer paper to be used at the same time as changing the filter 50,
Mistakes can be prevented by providing a display window 51 on the copying machine main body 10 and a display plate 52 on the filter 50 to display the color of the thermal transfer paper for each filter.

(Effects) According to the present invention, since the original is held down by the transparent original holding portion, the original is kept in a stable state during the copying operation, and copying can be performed in a stable state.
