Abstract

The invention relates to a photographic camera of high quality and extremely small dimensions. To this end the camera objective and the film track are provided on the front and rear faces, respectively, of a generally block-shaped central housing body. An upper housing portion extends on both sides laterally beyond the central housing body and carries, on its projecting parts, the film drive motor and a battery. A lower housing portion defines chamber members on both sides of the central housing body. These chamber members are open at the top and are interconnected by a rear wall and a bottom plate to define a space therebetween which accommodates the central housing body. The take-up and supply spools are located in the chamber members and, in turn, accommodate the film drive motor and battery, respectively, which project downwards from the upper housing portion.

Claims

1. Photographic camera comprising:

a hollow sleeve-shaped supply spool and a hollow sleeve-shaped take-up spool, a film track and a film engaging plate between said spools,

a camera objective, which is arranged to produce a real image in the plane of the film track,

a film driving motor which is coupled to the take-up spool,

an electronic control device and

a battery arranged to supply energy to the film driving motor and to the electronic control device, characterized in that

(a) the camera objective and the film track are provided on a generally block-shaped central housing body on opposite sides (front and read face) thereof,

(b) an upper housing portion is located on the upper side of the central housing body and extends on both sides beyond the central housing body,

(c) a lower housing portion forms a chamber member of substantially rectangular cross section below each of the laterally projecting parts of the upper housing body, said chambers accommodating said supply and take-up spools, respectively, said two chamber members being open towards the top and being interconnected by a rear wall and by a bottom plate, whereby a space is defined between the chamber members and the bottom plate, into which space the central housing body is removably inserted, vertical film passage slots being provided in the chamber members along the rear wall, and the film engaging plate being mounted on the rear wall, and

(d) the film drive motor is attached on one side to one of the projecting parts of the upper housing portion, and the battery is attached to the other one of the projecting parts on the other side of the upper housing portion, said film drive motor and said battery extending therefrom downwardly into the hollow take-up spool and supply spool, respectively, a coupling member mounted on the film drive motor being coupled directly to the take-up spool, when the central housing body is inserted.

2. Photographic camera as set forth in claim 1, characterized in that the chamber members are closed at the top by snap-in covers which have a circular aperture each therethrough permitting insertion and guiding of the film drive motor and of the battery, respectively, and which form bearings for the upper ends of the sleeve-shaped take-up and supply spools, respectively.

3. Photographic camera as set forth in claim 1 or 2, characterized in that

(a) each of the two sleeve-shaped spools has a pair of openings in its circumferential surface in a plane perpendicular to the spool axis in the area of the film perforation,

(b) an arcuate anchor body is mounted for rotation between two end positions about an axis parallel to the spool axis on the inner side of the spool between said openings, said anchor body ending in hooks at both ends,

(c) one hook extends outwards through one opening in one of the end positions, the other, oppositely pointing hook being retracted behind the wall of the spool, while, in the other end position, said other hook extends outwards and the first hook is retracted.

4. Photographic camera as set forth in anyone of the claims 1 to 3, characterized in that the imaging path of rays from the camera objective to the film track located lower than the camera objective is folded by two plane mirrors, each of which is arranged at an angle of 45°

with respect to the optical axis of the imaging beam.

5. Photographic camera as set forth in anyone of the claims 1 to 4, characterized in that the electronic control device is arranged substantially in the upper housing portion.

6. Photographic camera as set forth in anyone of the claims 1 to 5, characterized in that a photoelectric sensor for the automatic exposure control is arranged in a pupil of the path of rays of the camera objective.
