IPC: G02B7/08
Filed: 2003-03-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lens barrel which removes the backlash of helicoid screws, permits the light rotational motion of the helicoid screws and is simple in structure.  <P>SOLUTION: Biasing force is constantly applied to the female helicoid screw 88 of the lens barrel (outer tube) 70 via the male helicoid screw 102 from an anti-backlash spring 100 integrally born at the lens barrel (inner tube) 72. The male helicoid screw 102 is driven while it is pressed to the female helicoid screw 88. Accordingly, the backlash generated by the helicoid screws 88 and 102 can be removed. The anti-backlash springs 100, 100, etc., are formed in the outer peripheral part of the lens barrel 72 and therefore rotational torque can be surely transmitted and the male helicoid screw 102 hardly comes free from the female helicoid screw 88.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
