Filed:

Jan 24, 1980

Appl. No.:

6/114931

Inventors:

Stephen P. Hines - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 1700
G02B 2300

US Classification:

354286

Abstract:

Apparatus for maintaining in focus an image formed at the image plane of an optical instrument, notwithstanding random angular movement of the instrument's housing. Such apparatus includes mounting means for angularly decoupling the image-forming element (e. g. , a refractive lens) of the optical instrument from the instrument's housing, thereby allowing the image-forming element to move relative to such housing, and means for maintaining the focal plane of the image-forming element substantially parallel to the image plane of the optical instrument during relative angular movement between the image-forming element and the instrument's housing.

US Classification:

354145

Abstract:

Disclosed herein is a photographic camera having an integral flash unit which illuminates object space through the camera's viewfinder. According to a preferred embodiment, light from an energized flashlamp mounted within the camera interior is reflected into object space by means of a mirror which is pivotally mounted in the camera's viewfinder. Prior to shutter release, the mirror is stored in a position to allow normal use of the viewfinder. In response to actuation of the camera's shutter release mechanism, the mirror pivots to a position on the optical path of the viewfinder, whereupon it reflects light emanating from the flashlamp through the front of the viewfinder and into object space.

International Classification:

G03B 2130

G02B 308

US Classification:

353 70

Abstract:

A compact microimage viewing apparatus is disclosed which utilizes a low intensity light source with wide-angle projection optics to provide a clear and highly illuminated image to the viewer. To achieve compactness, the high brightness light-distributive screen of the viewing apparatus is located at an acute angle to the axis of projection of the projection lens. Keystone distortion of the projected image is substantially eliminated by employing a correcting lens, preferably a Fresnel lens, between the screen and the viewer at a predetermined angle to the screen such that the image portion projected onto the edge of the screen nearest to the projection lens, which would otherwise appear smaller to the viewer than would the image portion projected onto the farthermost edge of the screen, is magnified to an extent that a rectangular and substantially non-distorted image is presented to the viewer.

International Classification:

G03B 1704

US Classification:

354187

Abstract:

An improved bellows for use with a folding camera comprises a sheet of opaque resilient material, extending over an opening in the camera body. When the camera is folded, the bellows material is collapsed to a substantially flat plane, and when the camera is unfolded, the bellows material is expanded to define a light-tight, tent-like extension from the back of the camera. In a preferred embodiment of the invention, the bellows material possesses a dimpled, or wrinkled microstructure such that the material is expandable in any direction by unfolding the microstructure.
