Abstract

PURPOSE:To vary a common-use distance position to which a photographic lens is moved automatically as a protective cover is moved, by varying the position of relative coupling between a focusing ring and a coupling ring. CONSTITUTION:A camera is equipped with a photographic lens 3 which moves forth and back in the optical axis direction corresponding to distance adjusting operation, the protective cover 4 of the lens 3, and a coupling ring 60 which moves by some extent by coupling with the opening and closure of the protective cover 4, and further provided with a focusing ring 52 which moves the photographic lens 3 to a common-use distance position according to the movement of the ring 60. Then, the position of relative coupling between the coupling ring 60 and focusing ring 52 is varied by varying the position of engagement between a groove 60b and a pawl 52c, thus varying the common-use distance position to which the photographic lens 3 is moved automatically as the protective cover 4 is moved.
