Abstract

PURPOSE:To copy a slide film with a normal original copying machine by using a projection image receiver which is provided with a reflective mirror and a Fresnel lens and is attached freely on to a platen glass. CONSTITUTION:The slide set to a slide projecting machine 101 is projected onto a photosensitive drum 1 through a reflective mirror 107 and a Fresnel lens 108 and is copied with an electrophotographic copying machine 50. The reflective mirror 107 bends the optical path of the slide projecting machine 101, which projects the image horizontally, at right angles and directs the optical path toward the surface of a platen glass 4 of the electrophotographic copying machine 50. The Fresnel lens 108 may be obtained by superposing two Fresnel lenses, which function as cylindrical lenses and have grooves only in one direction, so that their grooves are orthogonal to each other, and this lens 108 functions to enlarge the projection image. A projection image receiver 140 including the reflective mirror 107 and the Fresnel lens 108 is folded freely and is attached and detached freely onto and from the glass 4.

Although we have not mentioned the mounting method of the reflecting mirror 107 and the Fresnel lens 108, for example, if the reflecting mirror 10
7 is attached to the second part 110 of the main body by adhesively fixing the cylindrical projections fixed to the four corners to the upper part 110 of the main body. Well, if the Fresnel lens 108 is placed over the opening on the lower part 111 of the main body, and the fixing plate 108', which has an opening of the same size as the Fresnel lens 108, is fixed to the lower part 111 of the main body using screws. It will be installed. Alternatively, the Fresnel lens 108 is inserted into the opening portion of a frame body having both openings and secured with screws, and the protrusion at the end of this frame body is fixed to the side surface of the lower body portion 111 with screws or the like. Alternatively, the Fresnel lens 108 and the reflective mirror 107 may be attached to the lower part 111 or the upper part 110 of the main body by other known methods.

Now, when it is desired to copy a transmitted enlarged projected image using a slide film, the locking mechanism that suppresses the rotation of the projection image receiver 1400 with respect to the upper body 1100 and the lower body 111 is released as described above, and the upper body 110 is rotated around the hinge 112. The connecting rod 114 moves the sliding portion 119b of the guide rail 119 to the left in FIG. With this movement, the stay 113 begins to rotate around the pin 115, and when it reaches a certain angle, the rotation is stopped and the connecting rod 114
is fitted into the fixed portion 119a of the guide rail 119, and the state 1 in FIG. 9 is reached. At this time, the angle between the reflecting mirror 107 and the Fresnel lens 108 is maintained at approximately 45°. This angle is the pin 1 which is the rotation center of the stay 113.
The angle adjustment plate 116 that fixes the pin 115 can be adjusted and fixed to the lower part 111 of the main body within its long portion 117, so that even if there is a rosewood between the parts, the angle adjustment plate 116 that fixes the pin 115 can be adjusted at approximately 45 degrees. Can be set. In this way, as shown in FIGS. 6 and 9, the open projected image receiving position 14
0 as shown in FIG. 3 and FIG.
23 is fitted into the fitting hole 123' of the copying machine main body 5o and mounted on the document table glass 4. However, the projection image receiving device 140
It is more preferable to attach it to the main body 5o of the copying machine and then open it as shown above.

After that, a slide projector 101 installed on the main body illuminates the reflector lamp 102 and the condenser 103° 104.
An enlarged image of the slide film 105 is projected. The enlarged image of the slide film 105 is reflected downward by the mirror 107 and is focused on the upper surface of the document platen glass 4 via the Fresnel lens 108 . fresnel lens 108
This is a struggle to condense the divergent light beam transmitted through the projection lens 106 toward the lens 8 on the main body side, as shown in FIG.

In the case of the present invention, even if the projection image receiving device 140 is repeatedly attached and detached from the copying machine main body 50 and repeatedly opened and closed, the positions of the reflecting mirror 107 and the Fresnel lens 108 have good reproducibility, so the angle adjustment is performed once. If the optical axes are then aligned as shown in FIG. 2, there is no need for subsequent optical adjustment when copying a projected image, which is very convenient.

Next, in response to the copy command, the drum 1 starts rotating about the shaft 2 in the direction of the arrow. When the drum 1 rotates to the normal position, an enlarged projected image of the slide film 05 formed on the document platen glass 4 is illuminated by an illumination lamp 6 integrated with the first scanning mirror 5 to enhance the contrast. The transmitted light of the softened enlarged projected image is scanned by a first scanning mirror 5 and a second scanning mirror 7. The first scanning mirror 5 and the second scanning mirror 7 move at a speed ratio of 1:1/2, so that the optical path length between the surface of the document platen glass 4 and the 8-inch lens is always kept constant. A scan of the image is performed.

The transmitted light image above is the lens 8. After passing through the third mirror 9, the colors are separated by a color separation filter 10, and then the fourth mirror 11.
The image is formed on the drum 1 at the exposure section 13 through the dust-proof sealed glass 12. After the drum 1 is neutralized by a static eliminator 14 and then charged (for example, positively) by a primary charger 15, the image formed by the slide projector 101 and illuminated by the illumination lamp 6 in the exposure section 13 is exposed to slit exposure. be done. At the same time, static electricity of opposite polarity (for example, negative) to AC or - is removed by the static eliminator 16, and a high-contrast electrostatic latent image is formed on the drum 1 on the subsequent page by full exposure with the full exposure lamp 17. .

When a normal original is to be copied, the projection image receiving device 140 is changed from an open state as shown in FIG. 9 to a closed state as shown in FIG. This operation is the opposite of the operation when changing the projection image receiving device 140 from the closed state to the open state, as described above, and is therefore self-explanatory, so a description thereof will be omitted. The thus closed projected image receiving device 140 is removed from the copying machine main body 50, and a normal original (not shown) is placed on the original platen glass 4.
