ABSTRACT:
According to the invention, a helicoid mechanism is provided at each side of a supporting member of the lens barrel fixed by a tripod seat or the like, the front one being intended for effecting the displacement of the lens while the rear one being intended for displacing the camera, whereby a larger stroke of the lens displacement which is materially twice the conventional one is obtained with machining precision of conventional helicoid means.
Means are provided for representing accurately the photo-taking distance, irrespective of whether either one of the front and rear helicoid mechanisms is solely adjusted, both of these helicoid mechanisms are individually adjusted or both of them are simultaneously operated, so as to render the operation of these helicoids free and to ensure an easier and more exact reading of the photo-taking distance.
