Filed: 1989-02-21
Abstract: PURPOSE:To easily determine the positions of plural lens holding frames for a 2nd group lens, a 3rd lens group, etc., by using a moving frame and a differential cam which moves axially in one body. CONSTITUTION:When a zoom ring 1 rotates while the lens barrel is in the state of the telephoto end, the moving frame 3 moves straight by a helicoid screw 1a toward the wide-angle end while a guide part 3a is guided to the straight movement guide groove 2a of a fixed frame 2. At the same time, the difference cam 4 is pressed through a differential cam sphere 18 by a cam pressure plate 9 fixed to the fixed frame 2 to move toward the wide-angle end integrally with the moving frame 3. At the same time, a driving pin 4a is guided to the bottomed cam groove 2b of the fixed frame 2, so that the driving pin rotates on the axis. The 2nd lens holding frame 6 and 3rd lens holding frame 7 move profiling cam surfaces 4b and 4c through the rotation of the differential cam 4, so the 2nd lens holding frame 6 moves to the mount side relatively to the moving frame 3 and the 3rd lens holding frame 7 moves forward differentially.
