When the copy start key is operated, the halogen lamp 5a
is turned on, and the light source unit 5 moves at a moving speed V/, where the transport speed of the microcapsule paper 12 is v1 and the projection magnification is m.
The reflection mirror 9a moves at m.

9b moves at a moving speed of V/2 m.

The conveyance speed of the microcapsule paper 12 is determined by the mirror group 8.9a.
, 9b is synchronized as described above,
Latent images of predetermined lines of the document 4 are sequentially formed on the microcapsule paper 12 as it passes through the exposure stage 11 . Note that the predetermined speed ratio is predetermined based on the setting of the magnification.

The microcapsule paper 12 on which the latent image has been formed is transported,
The topmost color developing paper 28 of the paper feed cassette 29 is fed to the paper feed mechanism 30.
．． It is conveyed by feed rollers 31a, 31b, 310, etc.

is wound onto the winding shaft 24 via the separation roller 23e.

Next, the operation when the copying machine of the present invention is used as a printer for a personal computer will be explained.

When the print start key is operated, the light source section 5 moves to the position of the reflective color LCD 50 and stops. The light source section 5 illuminates a halogen lamp 5a to irradiate light in a line toward the reflective color LCD 50 in a direction orthogonal to the movement direction. The irradiated light is reflected based on the image on the reflective color LCD 50. The reflected light is exposed and developed in the same manner as in the copying operation. The reflective color LCD 50 displays the data of the personal computer while scrolling at a constant speed. In addition, microcapsule paper 12
Since the feeding speed is synchronized with the scrolling speed of the reflective color LCD 50, printing can be performed without color shift.

The flow of operation of the copying apparatus 1 will be explained with reference to FIGS. 2 and 3. The CPU 104 operates according to the program contents of the PGROM (program read-only memory) 103. The CPU 104 first monitors the copy start key at SL and the print start key at S2, and waits until either key is pressed (SL, 82).

Both keys are provided within the key panel 102. When the copy start key is pressed, the CPU 104 performs a normal copy operation (S8), but the copy operation will not be described in detail here. When the print start key is pressed, the CPU
104 transfers image data from an externally connected personal computer to a VRAM (video random access memory) 105 via the interface 101 (S3). When the transfer is completed, the CPU 104 controls the light source position control circuit 10.
Send the light source position data during printing to 6, move the light source to the bottom of the reflective color LCD 50, and stop it (
S4).

Next, the CPU 104 turns on the halogen lamp 5a using the halogen lamp control circuit 109 (S5). VRA
The contents of M(7) are scroll-displayed on the reflective color LCD 50 by the LCD controller 107 and LCD driver 108, and the microcapsule paper 12 is exposed to the reflected light (S6). Then, the latent image formed by exposure is output as an image through development processing (S7), and this flow ends.

The present invention is not limited to the embodiments detailed above, and various changes can be made without departing from the spirit thereof. For example, in this embodiment, a reflective color LCD is used, or a reflective LCD and red, green, and blue filters may be combined. Furthermore, instead of the reflective type, it is also possible to use a self-luminous type display device such as an electroluminescence display, a light emitting diode, or a plasma display.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, since a part of the document table is provided with an image display means, it can also be used as a printer, and the range of application of the device is wide. Compared to two machines, a copier and a printer, it costs less and requires only one installation area, making it economical and space-saving.
