Abstract

The auto-focus binocular (or non- binocular) viewfinder may be attached to the camera, or built into it as an integral part; its binocular viewing facility increases in a great measure the making evaluations of the selected subjects. <IMAGE>

Description

SPECIFICATION The auto-focus binocular or non-binocular viewfinder which may be attached to or built-in a camera At present the camera user has to view his subject in a diminutive through the camera's tiny frame of a square or of a rectangular format, which condition does inevitably impair the user's ability for obtaning a correct artistic evaluation of the selected topics, such as the animated life incidents, the sceneries, the portraiture, & .

In order of remedying this prior art's disadvantage, I did invent an Auto-focus Binocular (or single occular) Attachment to cameras (N.B. The said system is suiable for being built-in as an integral part of a camera). At the time I was unable to persue the invention further owing to absence of a clear-defined principle-the principle, which only in 1976 I succeeded in discovering. Now, however, in 1986 1 do understand it fully, and am able to utilise it and explain (see drawings) 1,2, and 3).

The said principles which do underly the inventions of my earlier, published by the UK Patent Office, specifications, whose serial numbers are as follows: 1097643, 21380, 1640827, 2129574, 2173015.

Description.

The device of this Specification consists of the parts as follows: at the first sight the device shows the camera on its platform, the connecting prongs, the binocular viewfinder's panel, and the X-flash holder bracket.

The description in particular begins from the camera platform (0) which provides an elongated and extra wide opening for the reception of the camera-socket and for the corresponding camera-screw. This level platform is attached at right-angles to the said upright panel (P), which on its part has at its back an "U"-shaped unit (0) attached by means of a pivot to the back of the camera's platform (P).

The unit (0) apart its pivot, has a pair of prongs (N2) which do tally in size and slots with the upper pair of similar prongs (J) and slots (K), which belong to the viewfinder's panel (H2). Thus, by means of the upper and lower prongs and of corresponding slots, a firm juncture is effected by the aid of a pair of screws (L). The camera-platform's arrangement (P+G) has a provision for setting the camera at a level or an upright positions (S).

The upper panel (H2) represents the binocular viewfinder-there are two circular, (alternatively square or rectangular shaped) re-adjustable oculars, so as to match their field of vision with that of the camera's one. Between the said two oculars there is situated a re-adjustable nasal support (E) to which there is attached a piece of split leather to provide for the nasal comfort. The (H2) panel, moreover, has a narrow platform (D) which accomodates a pair of screws (C), plus a bracket (A)-both constituting a facility for the attachment of an X-flash (B).

Reference to drawings: Figure 1-Schematic, pictorial and diagrammatic, it represents a binocular, auto-focused, viewfinder attachment to cameras-an attachment which is underlied by the principle as diagramed by the Figs. 2 and 3.

Figure 2-Diagramatic, showing the camera in relation to the viewfUnder/auto-focus principle, and the mode of attachment.

Figure 3-Diagramatic, ditto, especially for the cameras which would incorporate integrally the binocular, or non-binocular auto-focus, viewfinder system, as explained by the drawings Nos. 2 and 3.

CLAIMS 1. The binocular or non-binocular auto-focus viewfinder attachment to cameras, underlied by the diagramed principles of the Figs. 2 and 3.

2. The binocular or non-binocular auto-focus viewfinder to cameras, & ., in which the said system and its principles are incorporated integrally into a camera, according to principles as depicted by the diagrams of the Figs. 2 and 3.

3. The binocular or non-binocular auto-focus viewfinder attachment to cameras, & ,, according to Claim 1, having a rotary cameraplatform enabling the setting of a camera into a level or upright positions.

4. The binocular or non-binocular auto-focus viewfinder attachment to cameras, & ., according to Claims 1, having a facility for the uplifting or for the lowering down the binocular or non-binocular A.F. viewfinder.

5. The binocular or non-binocular auto-focus viewfinder attachment to cameras, & ., according to Claims 1,3 and 4, of which the camera-platform's back panel (the shaded one), has an "U"-shaped unit of a pair of slotted prongs, in between which there's a pivot, whose centre finds itself opposit the centre of the camera's imaging lens.

6. The binocular or non-binocular auto-focus viewfinder attachment, & ., according to Claims 1,3,4 and 5, whose viewfinder's panel has also a pair of corresponding prongs as those belonging to the "U"-shaped unit; thus the upper and the lower pairs of prongs do tally together, by means of which a firm juncture of the attachment's upper and lower parts is achieved by the aid of a pair of screws.

7. The binocular or non-binocular auto-focus viewfinder attachment to cameras, according to Claims 1,3,4,5 and 6, having a panel comprising a pair of re-adjustable, circular viewers; alternatively these viewers may be of
