ABSTRACT:
A video camera includes a flangeback adjusting mechanism including a front panel having a threaded opening through which an optical lens is mounted from an outer side of the camera. An adjusting ring is engaged at the inner side of the threaded opening and is movable in an axial direction according to rotation thereof. On either side of the adjusting ring, guide rods project from an inner face of the front panel, mounting thereon a holder which supports an image pickup device. Nuts are affixed to the ends of the guide rods and coil springs are fitted around the guide rods between the nuts and a rear face of the holder so as to bias the holder in the forward direction.
