ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to an interchangeable miniature-film magazine.
SUMMARY OF THE INVENTION
An object of the present invention is to develop an interchangeable miniature-film magazine in as compact a design as possible.
According to one aspect of the present invention, an interchangeable miniature-film magazine, comprises: a magazine housing and a receiver located in the housing for receiving a film cassette that houses film. The interchangeable miniature-film magazine further includes a sprocket located in the housing for advancement of the film, a winding drum that is arranged in the housing in close proximity to the film cassette to wind the film, and a shutter for closing a film gate located in the housing. The sprocket is located a first distance from an outlet of the film cassette. The first distance is smaller than a second distance which corresponds to a width of the film gate.
According to another aspect of the present invention, the interchangeable miniature-film magazine is arranged such that the film is guided within the housing along a first film path from the winding drum around an outside of the film cassette, along a second film path parallel to an image plane corresponding to the film gate, along a third film path around an outer diameter of the sprocket, and along a fourth film path from the sprocket to the outlet of the film cassette.
Further features of the invention form the subject matter of the claims and will be explained in more detail, in conjunction with further advantages of the invention, with reference to an exemplary embodiment.
