Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
A photographic camera comprising a camera body having a front face and a taking lens inset in said camera body to not project outwardly substantially from said front face, is characterized in that: photosensor means is located in the vicinity of said taking lens for emitting a light beam towards a camera user's finger that may be positioned over the taking lens and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said photosensor means for providing a warning that a camera user's finger may be positioned over said taking lens when the photosensor means detects reflection of a light beam from the camera user's finger.
Claim 2
Dependent Claim
115 words
A photographic camera comprising a camera body having a front face and a taking lens inset in said camera body to not project outwardly substantially from said front face, is characterized in that: photosensor means is located in the vicinity of said taking lens for emitting a light beam towards a camera user's finger that may be positioned over the taking lens and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said photosensor means for providing a warning that a camera user's finger may be positioned over said taking lens when the photosensor means detects reflection of a light beam from the camera user's finger.
Claim 3
Dependent Claim
86 words
A photographic camera as recited in claim 1, further comprising a shutter release button supported on said camera body for manual depression to take a picture and a trigger switch that changes state responsive to manual depression of said shutter release button, and wherein said photosensor means is connected to said trigger switch to emit a light beam towards a camera user's finger that may be positioned over said taking lens when the trigger switch changes state responsive to manual depression of said shutter release button.
Claim 4
Dependent Claim
51 words
A photographic camera as recited in claim 2, further characterized in that: shutter disablement means is connected to said photosensor means for preventing the taking of a picture when the photosensor means detects reflection of a light beam from a camera user's finger that may be positioned over said taking lens.
Claim 5
Dependent Claim
64 words
A photographic camera as recited in claim 1, further comprising a camera viewfinder, and wherein said alarm means includes a light-emitting diode located to be seen in said viewfinder for providing a warning visible in the viewfinder that a camera user's finger may be positioned over said taking lens when said photosensor means detects reflection of a light beam from the camera user's finger.
Claim 6
Dependent Claim
54 words
A photographic camera as recited in claim 1, wherein said photosensor means includes an infrared emitter for emitting a beam of infrared light towards a camera user's finger that may be positioned over said taking lens and an infrared detector for detecting reflection of the beam of infrared light from the camera user's finger.
Claim 7
Dependent Claim
211 words
A photographic camera comprising a camera body having a front face, a taking lens inset in said camera body to not project outwardly substantially from said front face, and an electronic flash unit inset in said camera body to not project outwardly substantially from said front face, is characterized in that: first photosensor means is located in the vicinity of said taking lens for emitting a light beam towards a camera user's finger that may be positioned over the taking lens and for detecting reflection of the light beam from the camera user's finger; second photosensor means is located in the vicinity of said flash unit for emitting a light beam towards a camera user's finger that may be positioned over the flash unit and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said first photosensor means and to second photosensor means for providing a warning that a camera user's finger may be positioned over said taking lens when the first photosensor means detects reflection of a light beam from the camera user's finger or that a camera user's finger may be positioned over said flash unit when photosensor means detects reflection of a light beam from the camera user's finger.
Claim 8
Dependent Claim
211 words
A photographic camera comprising a camera body having a front face, a taking lens inset in said camera body to not project outwardly substantially from said front face, and an electronic flash unit inset in said camera body to not project outwardly substantially from said front face, is characterized in that: first photosensor means is located in the vicinity of said taking lens for emitting a light beam towards a camera user's finger that may be positioned over the taking lens and for detecting reflection of the light beam from the camera user's finger; second photosensor means is located in the vicinity of said flash unit for emitting a light beam towards a camera user's finger that may be positioned over the flash unit and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said first photosensor means and to second photosensor means for providing a warning that a camera user's finger may be positioned over said taking lens when the first photosensor means detects reflection of a light beam from the camera user's finger or that a camera user's finger may be positioned over said flash unit when photosensor means detects reflection of a light beam from the camera user's finger.
Claim 9
Dependent Claim
82 words
A photographic camera as recited in claim 6, further characterized in that: disablement means is connected to said first photosensor means and to said second photosensor means for preventing the taking of a picture when the first photosensor means detects reflection of a light beam from a camera user's finger that may be positioned over said taking lens or the second photosensor means detects reflection of a light beam from a camera user's finger that may be positioned over said flash unit.
Claim 10
Dependent Claim
96 words
A photographic camera as recited in claim 6, wherein said alarm means includes first alarm means connected to said first photosensor means for providing a warning that a camera user's finger may be positioned over said taking lens when the first photosensor means detects reflection of a light beam from the camera user's finger and second alarm means connected to said second photosensor means for providing a warning that a camera user's finger may be positioned over said flash unit when the second photosensor means detects reflection of a light beam from the camera user's finger.
Claim 11
Dependent Claim
116 words
A photographic camera comprising a camera body having a front face, and an electronic flash unit inset in said camera body to not project outwardly substantially from said front face, is characterized in that: photosensor means is located in the vicinity of said flash unit for emitting a light beam towards a camera user's finger that may be positioned over the flash unit and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said photosensor means for providing a warning that a camera user's finger may be positioned over said flash unit when the photosensor means detects reflection of a light beam from the camera user's finger.
Claim 12
Dependent Claim
116 words
A photographic camera comprising a camera body having a front face, and an electronic flash unit inset in said camera body to not project outwardly substantially from said front face, is characterized in that: photosensor means is located in the vicinity of said flash unit for emitting a light beam towards a camera user's finger that may be positioned over the flash unit and for detecting reflection of the light beam from the camera user's finger; and alarm means is connected to said photosensor means for providing a warning that a camera user's finger may be positioned over said flash unit when the photosensor means detects reflection of a light beam from the camera user's finger.
