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.
Claims19
A video camera having a focusing mechanism, comprising:
- a front panel having a threaded opening for receiving a lens screwed from a front side thereinto;
- holding means for holding an image pickup device;
- connecting means movably connecting said holding means to said front panel along an optical axis of said lens, wherein said connecting means further comprises a plurality of guide rods being mounted on said front panel and biasing means biasing said connecting means in a direction parallel to the optical axis;
- slider means arranged between said front panel and said holder means, said slider means having a threaded portion engaged with said threaded opening and a contact plane contacting with said holding means so that a distance between said lens and said image pickup device can be adjusted by screwing said slider means into or out of said threaded opening, wherein said slider comprises a smaller diameter forward portion having said threaded portion in the form of a threaded outer circumference engaging with said threaded opening, and a larger circumference rearward portion, said contact surface being a rear face of said rearward portion.
