Abstract
Abstract Disclosed is a film cassette of a kind which contains an electrophotographic film therein and which is adapted to be loaded in an electrophotographic camera processor-reader. The film cassette includes a cassette casing formed with a reflecting-mirror insertion cavity into which a reflecting mirror is inserted in inclined relation for reflecting light emitted from a projecting light source to direct the light toward a projecting lens. Because of no necessity for incorporation of the elements including the projecting light source and reflecting mirror in the cassette casing, the size and weight of the film cassette itself can be reduced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A film cassette of a kind which contains an electrophotographic film in web form therein and which is adapted to be loaded in an electrophotographic camera processor-reader recording picture image data on the electrophotographic film and projecting the picture image data recorded on the electrophotographic film, said film cassette comprising a cassette casing containing a pair of rotatable reels around which the electrophotographic film is wound at both ends thereof, an aperture formed in said cassette casing to be positioned opposite an electrophotographic process head mounted on said electrophotographic camera processor-reader including a charging section, an exposure section, a developing section and a fixing section for sequentially performing a series of processing on the electrophotographic film in the above order, and a reflecting-mirror insertion cavity formed in said cassette casing to permit insertion, in inclined relation therein, of a reflecting mirror reflecting light emitted from a projecting light source of said electrophotographic camera processor-reader to direct the light toward a projecting lens of said electrophotographic camera processor-reader.
Claim 2
Dependent Claim
167 words
A film cassette of a kind which contains an electrophotographic film in web form therein and which is adapted to be loaded in an electrophotographic camera processor-reader recording picture image data on the electrophotographic film and projecting the picture image data recorded on the electrophotographic film, said film cassette comprising a cassette casing containing a pair of rotatable reels around which the electrophotographic film is wound at both ends thereof, an aperture formed in said cassette casing to be positioned opposite an electrophotographic process head mounted on said electrophotographic camera processor-reader including a charging section, an exposure section, a developing section and a fixing section for sequentially performing a series of processing on the electrophotographic film in the above order, and a reflecting-mirror insertion cavity formed in said cassette casing to permit insertion, in inclined relation therein, of a reflecting mirror reflecting light emitted from a projecting light source of said electrophotographic camera processor-reader to direct the light toward a projecting lens of said electrophotographic camera processor-reader.
Claim 3
Dependent Claim
37 words
A film cassette as claimed in claim 1, wherein a light shielding tape is connected to at least one end of the electrophotographic film to provide an end portion of said electrophotographic film extending between said reels.
Claim 4
Dependent Claim
16 words
A film cassette as claimed in claim 2, wherein said light-shielding tape is a magnetic tape.
Claim 5
Dependent Claim
44 words
A film cassette as claimed in claim 3, wherein a magnetic-tape insertion cavity permitting insertion of a magnetic head incorporated in said electrophotographic camera processor-reader is formed in said cassette casing adjacent to said aperture adapted to be positioned opposite said electrophotographic process head.
Claim 6
Dependent Claim
34 words
A film cassette as claimed in claim 4, wherein said cavities formed in said cassette casing to receive said reflecting mirror and said magnetic head inserted therein respectively are combined into a single cavity.
Claim 7
Dependent Claim
48 words
A film cassette as claimed in claim 1, wherein a resilient member pressing one of the axial ends of said reels thereby resiliently bias the other axial end of said reels toward the inner wall of said cassette casing is interposed between said cassette casing and said reels.
