    摘要： A light intercepting apparatus of a lens barrel has a pair of lens frames which support a pair of lens groups, with the lens groups being movable with respect to one another in an optical axis direction. The apparatus further includes a light intercepting portion which isolates an optical path between the lens groups from external light. The light intercepting portion includes a pair of annular light intercepting members which are supported by the pair of lens frames in a manner such that the pair of annular light intercepting members are movable with respect to each other in the optical axis direction. The pair of annular light intercepting members include a pair of engaging portions which define a latch portion of the light intercepting apparatus and which prevent motion of the annular light intercepting members beyond a maximum extended position of the pair of annular light intercepting members.

    摘要： A camera having an apparatus for adjusting a back focus by varying a distance between a rearmost point of lens groups of a photographing optical system and focal plane. The apparatus includes a stationary barrel that supports the lens groups and is fixed to the camera body, and a restricting mechanism that is provided between the camera body and the stationary barrel. The restricting mechanism restricts rotational movement of the stationary barrel with respect to the camera body, while allowing movement of the stationary barrel in an optical axis direction with respect to the camera body.

    摘要： A method for producing a male helicoid molding die which is adapted to manufacture an inner barrel having a male helicoid, and for producing a female helicoid molding die which is adapted to manufacture an outer barrel having a female helicoid which can engage with said male helicoid of the inner barrel. The method includes the steps of firstly, setting an included angle of trapezoidal threads of the male helicoid to be identical to an included angle of trapezoidal grooves of the female helicoid in a section perpendicular to a direction of an extension of the threads and preparing a cutting tool having an angle identical to the set angle. Secondly, the male helicoid molding die is machined to form a helicoid portion thereof using the cutting tool. Next, an electric spark machining electrode is prepared having a helicoid portion whose shape is identical to a shape of the helicoid portion of the male helicoid molding die, by a mechanical cutting operation, using the cutting tool. Then a helicoid portion of the female helicoid molding die is formed by electric spark machining using the electric spark machining electrode.
