ABSTRACT:
A camera housing of substantially conventional construction includes a lens housing guide member substantially normal to the camera housing along which the lens housing is slideably moveable. The lens housing includes means which cooperate with the guide member, the lens housing being axially displaceable relative to the camera housing along the guide member on the means. A biasing means connects the lens housing and the camera housing, and statically determines constant engagement between the guide member and means provided on the lens housing which cooperate therewith. A support bearing is journaled on a cam member which is mounted on the lens housing. The support bearing is slideable on a bearing surface provided in the camera housing. The camera housing includes a means having a camming surface which cams along the cam member on the lens housing so as to axially displace the lens housing relative to the camera housing along the guide member and against the bias provided by the biasing means.
