Abstract
Abstract A photographic camera system including a mode setting device for selectively setting the system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone, a recording device for recording on a film information corresponding to one of the photographing modes, a data imprinting device for imprinting data such as the date at one of different positions on a photographing portion of the film and a selector device for selecting one of the different positions in accordance with one of the photographing modes. The photographic camera system includes a light shield which blocks a portion of the light in the pseudo focal length photographing mode and which does not block light in real the focal length photographing mode.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which would otherwise pass through a taking lens and fall upon a range of a screen frame outside a photographic zone to be printed as determined by said mode setting means, said light shielding means comprising a lens hood which is slidable, in operative association with said mode setting means, relative to a lens barrel of a camera body of said photographic camera system in a direction of an optical axis of said lens barrel.
Claim 2
Dependent Claim
134 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which would otherwise pass through a taking lens and fall upon a range of a screen frame outside a photographic zone to be printed as determined by said mode setting means, said light shielding means comprising a lens hood which is slidable, in operative association with said mode setting means, relative to a lens barrel of a camera body of said photographic camera system in a direction of an optical axis of said lens barrel.
Claim 3
Dependent Claim
130 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which has passed through a taking lens and which would otherwise fall upon a range of a screen frame outside a photographic zone to be printed as determined by the mode setting means, wherein said light shielding means comprises a light shielding member which is disposed in an image plane frontal area of a camera body of said photographic camera system so as to be operatively associated with said mode setting means.
Claim 4
Dependent Claim
130 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which has passed through a taking lens and which would otherwise fall upon a range of a screen frame outside a photographic zone to be printed as determined by the mode setting means, wherein said light shielding means comprises a light shielding member which is disposed in an image plane frontal area of a camera body of said photographic camera system so as to be operatively associated with said mode setting means.
Claim 5
Dependent Claim
130 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which would otherwise pass through a taking lens and fall upon a range of a screen frame outside a photographic zone to be printed as determined by said mode setting means, said light shielding means moving in connection with the setting operation of said mode setting means between a first position where said light shielding means blocks light and a second position where said light shielding means does not block light.
Claim 6
Dependent Claim
130 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking at least a portion of light which would otherwise pass through a taking lens and fall upon a range of a screen frame outside a photographic zone to be printed as determined by said mode setting means, said light shielding means moving in connection with the setting operation of said mode setting means between a first position where said light shielding means blocks light and a second position where said light shielding means does not block light.
Claim 7
Dependent Claim
105 words
A photographic camera system comprising: a mode setting means for selectively setting said photographic camera system to a real focal length photographing mode for printing an ordinary photographic zone and a pseudo focal length photographing mode for printing a zone narrower than the ordinary photographic zone; and a light shielding means for blocking, in the pseudo focal length photographing mode, at least a portion of light which would otherwise pass through a taking lens and fall upon a range of a screen frame, the range being printed in the real focal length photographing mode but not being printed in the pseudo focal length photographing mode.
Claim 8
Dependent Claim
