。Next, the OHP sheet 1-46 to be projected is placed on the document table 44''2, and the power switch is turned on. Then, the mirror 45 is set at a predetermined position in the direction of arrow F, and the reflecting plate 83 is retracted in the direction of arrow 1. Next, by operating the selection button 210, an image to be used as a light source is selected. The image is from a TV/VTR connected to the input interface 200.
・The output of a computer, fax, etc. or white light. When white light is selected, only the image on the OHP sheet is projected, and when other is selected, the output image of the selected device is superimposed on the image on the OHP sheet. Further, if the OHP sheet is not placed on the document table 44'2, only the image from the projector TV projector 42 is projected.

れたことになる。Furthermore, when making a copy of the OHP sheet 46 placed on the document table 44, the mirror 45 is rotated in the direction of arrow E, and the reflective plate 83 is rotated in the direction of arrow J to hold down the OHP sheet 46. At the same time, the Fresnel lens 84 is retracted in the direction of the arrow in FIG. Then, when the copy start button (not shown) is pressed, the copy light source 48 lights up and the exposure unit 50 or arrow B is pressed, as shown in FIG.
Scan exposure in the direction. The reflected light from the OHP sheet 46, which is the original, is reflected by the folding mirror 49, 51 and begins to expose the photosensitive recording medium 53. In synchronization with the scanning of the exposure unit 50, the photosensitive recording medium 53 is moved in the same direction. When the exposure for one screen is completed, the exposure unit 50 moves back in the direction of arrow A and returns to its original position. On the other hand, a latent image of a desired color image is recorded on the photosensitive recording medium after exposure.
