ABSTRACT:
A receiving device for a film cassette, having a light-proof housing. The housing includes a film-advancing device which is assigned a gripping region for the start of the film projecting out of the film cassette. In order to facilitate insertion of the film into the camera body or into a magazine, the receiving device can be pivoted or drawn out of the housing, with parallel shifting of the axis of rotation of the receiving device, thus allowing insertion or removal of the film cassette. In the open position the inserted film cassette is spaced apart from the film-advancing device by a greater distance than in the closed position. The distance of the inserted film cassette from the gripping region in the open position is of such a size that the start of the film projecting out of the film cassette, even in the case of the smallest commercially available length, extends almost right up to the gripping region. The receiving device has a rotatably mounted cassette driver which, via a form fit or friction fit, is in rotational connection with the inserted film cassette. Upon closure of the receiving device, the cassette driver, under the action of a pushing force directed from the start of the film onto the film outlet, can be rotated, counter to the action of a resiliently elastic element, in a direction which is oriented counter to the closing movement of the receiving device. As a result, upon closure of the receiving device, the start of the film in the gripping region is retained.
