Abstract: 996, 334. Photographic copying apparatus; focusing devices. EASTMAN KODAK CO. March 9,1962 [March 14,1961], No. 9095/62. Headings G2A and G2J. A photographic copying apparatus has a camera 11 and a platen 15 for carrying the document to be copied, both mounted on a support so that their distance apart can be adjusted; rigidly attached to the camera is a means for projecting two flat beams of light on to the document, the arrangement being such that when the two lines coincide to form a single line, the document is at the correct distance from the camera. In the form shown, the projecting means is a housing 1 containing a light source 3 and a reflector 4, and having two parallel slits 5, 7. Slit 5 directs a flat beam of light 6 directly from the source 3 on to the copying surface 13 of the document, and slit 7 directs a second beam 8 reflected from mirror 4. These form two lines of light on the surface 13. This is then moved towards or away from the camera until these two lines coincide (point 9, or line B-B in Fig. 4). The surface 13 is now at the correct distance from the camera. Instead of the slits 5, 7 being equal in length, alternate halves of each may be blocked, so that the two lines of light on surface 13 will be as shown at A-A, A<SP>1</SP> -A<SP>1</SP>. When brought into the coincidence position, the half-lines will apparently join end-to-end in a single line. A further slit 18 throws a further beam of light intersecting surface 13 at 20 (or line C-C). Lines B-B and C-C indicate the limits of the field reflecting illumination to an exposure meter 16, so that the surface being copied can be moved about to bring the part required to the best exposure between these two lines. The invention may be applied to an automatically focusing copying camera.
