1,203,091 Lens mounts. EASTMAN KODAK CO. Aug.17, 1967 [Aug.23, 1966, No.37964/67. Heading G2J. [Also in Division H4] A photographic camera includes a range-finder for indentifying from a plurality of zones at different distances from the camera the particular zone in which an object to be photographed is located, the range-finder comprising light (visible, infrared or ultraviolet) source means for projecting several light beams from the camera, or several photocells, for defining zones along a path towards which the camera is pointed. In one embodiment lamps 30, 31 Fig. flash intermittently and sequentially from respective capacitors, and a single photo-cell 47 controls a latch 50. In another embodiment a single lamp 51 Fig.6 is utilized in conjunction with photo-cells 54, 55 arranged as shown in Fig.7. The range-finder is actuated by depressing member 77 and member 74 is urged counterclockwise by a spring (not shown), this rotation closes contacts 81, 82 to energize lamp 51 and amplifiers 61, 63. Switches 62, 64 actuate respective solenoids 65, 66 to cause movement of linkage 67 to permit lug 74 to travel to a position corresponding to the zone in which the object to be photographed lies, Figs. 8 to 11 (not shown). Automatic focusing may be arranged. Other arrangements not falling within the scope of the invention are described and are "continous" rather than "zone" systems, Figs. 1 to 4 (not shown). Specification 1,196,771 is referred to. |
