Abstract
A camera including an automatic lens focusing system, wherein a disc holding a plurality of different lens elements is rotated to sequentially present the lens elements at a focusing system, is provided with a disc stopping arrangement comprising a plurality of notches in a peripheral section of the disc and a pawl having a tang therein configured to be received in a selected one of the notches to stop disc rotation and locate a corresponding one of the lens elements at the focusing position. The outer edge portion of the disc, the notches and the pawl tang are specially configured so as to stabilize the pawl prior to tang entry into a notch and to efficiently dissipate inertial energy of the disc.
