Abstract
A lens mounting apparatus for television cameras, which is provided with a lens mounting mechanism having a cylindrical lens holder capable of mounting thereto a lens, a ring mechanism having at the inner periphery slanted cam faces and rotatably and slidably supported to the lens holder, a bracket member holding an image pickup element and slidably supported to the lens mounting mechanism, an elastic member for biasing the bracket member in the direction of the optical axis of the lens mounting mechanism, and projections fixed to the outer periphery of the lens holder and abutting against the slanted cam faces at the ring mechanism, so that the bracket member biased by the elastic member urges the ring mechanism so as to regulate a movement of the ring mechanism in the direction of the optical axis by abutting the slanted cam faces against the projections, the ring mechanism being rotated to move the bracket member toward or away from the lens mounting mechanism, thereby enabling a flange back distance to be changed with ease.
