Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
157 words
A photographic camera having a real focal length photographing mode in which a normal range in a frame of a film will be printed on the photographing paper and a pseudo focal length photographing mode in which a range smaller than the normal range in a frame of the film will be printed on a photographic paper, said photographic camera comprising: a mode selecting means for selecting one of said real focal length photographing mode and said pseudo focal length photographing mode; means for winding the film by an identical length for every shot regardless of the selection of the photographing mode by said selecting means; and a light shielding means for shielding at least a portion of the normal range in a frame of the film in the case where said pseudo focal length photographing mode was selected, said portion being limited to a portion of said film which is not to be utilized upon printing.
Claim 2
Dependent Claim
157 words
A photographic camera having a real focal length photographing mode in which a normal range in a frame of a film will be printed on the photographing paper and a pseudo focal length photographing mode in which a range smaller than the normal range in a frame of the film will be printed on a photographic paper, said photographic camera comprising: a mode selecting means for selecting one of said real focal length photographing mode and said pseudo focal length photographing mode; means for winding the film by an identical length for every shot regardless of the selection of the photographing mode by said selecting means; and a light shielding means for shielding at least a portion of the normal range in a frame of the film in the case where said pseudo focal length photographing mode was selected, said portion being limited to a portion of said film which is not to be utilized upon printing.
Claim 3
Dependent Claim
31 words
A photographic camera as claimed in claim 1, further comprising a recording means for recording an information related to the selected mode within the range shielded by said light shielding means.
Claim 4
Dependent Claim
52 words
A photographic camera comprising: means for winding a film by an additional length for every shot; and means for shielding at least a portion of a normal range in a frame of the film, said portion being limited to a portion of the film which is not to be utilized upon printing.
Claim 5
Dependent Claim
52 words
A photographic camera comprising: means for winding a film by an additional length for every shot; and means for shielding at least a portion of a normal range in a frame of the film, said portion being limited to a portion of the film which is not to be utilized upon printing.
Claim 6
Dependent Claim
23 words
A photographic camera as claimed in claim 3, wherein said shielding means is adapted to shield the upper portion of the normal range.
Claim 7
Dependent Claim
23 words
A photographic camera as claimed in claim 3, wherein said shielding means is adapted to shield the lower portion of the normal range.
Claim 8
Dependent Claim
38 words
A photographic camera comprising: means for shielding the upper portion of a normal range in a frame of a film, said portion being limited to a portion of the film which is not to be utilized upon printing.
Claim 9
Dependent Claim
38 words
A photographic camera comprising: means for shielding the upper portion of a normal range in a frame of a film, said portion being limited to a portion of the film which is not to be utilized upon printing.
Claim 10
Dependent Claim
