Abstract
A view finder of a zoom lens camera including a zoom lens, an object distance measuring device having a light emitter and a light receiver, and a zoom finder device which varies the field of view of the finder in association with the zoom lens. The zoom finder device is placed between the light emitter and the light receiver of the object distance measuring device.
Claims24
View finder apparatus of a zoom lens camera, said view finder apparatus comprising:
- a zoom lens;
- an object distance measuring device having a light emitter and a light receiver;
- a zoom finder device comprising means for varying the field of view of said zoom finder device in association with said zoom lens, said zoom finder device being positioned between said light emitter and said light receiver of said object distance measuring device;
- a strobe positioned so that one of said light emitter and said light receiver is positioned between said strobe and said zoom finder device;
- and
- means for associating movement between said zone finder device and said strobe so that said strobe is moved in response to movement of said zoom finder device.
A zoom lens camera comprising:
- a zoom lens;
- a view finder assembly including a view finder, an object distance measuring device having a light emitter and a light receiver, and a zoom finder device which varies the field of view of said view finder in association with the zoom lens, said zone finder device being positioned between said light emitter and said light receiver of said object distance measuring device;
- a zoom strobe device positioned so that one of said light emitter and said light receiver is positioned between said zoom strobe device and said view finder, said zoom strobe device having an illuminating angle varying mechanism for varying the illuminating angle of the zoom strobe device in association with the zoom lens;
- and
- means for associating movement between said zoom finder device and said illuminating angle varying mechanism;
- said zoom strobe device comprising an illuminating angle varying member movable in the optical axis direction;
- said zoom finder device comprising a variable power lens group movable in an optical axis direction of the zoom lens, and an association drive mechanism for driving said variable power lens group in association with a zooming operation of the zoom lens;
- said zoom lens camera further comprising a first association lever which rotates in association with movement of said variable power lens group, a second association lever which rotates in association with movement of said illuminating angle varying member, and gear portions provided on said first and second association levers, to engage with each other, wherein said illuminating angle varying member and said zoom finder device are associated by said first and second association levers and gear portions.
Apparatus including a zoom finder having a variable power lens group movable in an optical axis direction and a zoom strobe device having an illuminating angle varying mechanism movable in the optical axis direction, wherein the variable power lens group and the illuminating angle varying mechanism are associatively moved, said apparatus comprising:
- a driving apparatus of the zoom strobe having racks provided on the variable power lens group and the illuminating angle varying mechanism and extending in the optical axis direction, and a gear train provided between said racks through which the variable power lens group and the illuminating angle varying mechanism are associatively moved.
The apparatus of claim 26, wherein the variable power lens group is mounted in a camera having a power zoom lens, and in which the magnification thereof is varied in accordance with a zooming operation of said power zoom lens.
