ABSTRACT:
In a collapsible mount type camera, a transmission pin provided in a lens barrel is movable back and forth as a distance ring or aperture size control ring is rotated. The rear end of the transmission pin is projected rearward out of the lens barrel. The rear end of the pin is integrally fixed to a radially extending lever which extends beyond the periphery of the lens barrel. On the outer end of the radially extending lever abuts a rear end of an intermediate lever pivotally mounted in a camera body. When the lens barrel is retracted into the camera body, the lens barrel with the transmission pin is not obstructed by the intermediate lever.
