Abstract
Abstract A photographic camera includes a lens carrier with alternative taking lenses having shorter and longer focal lengths. The lens carrier is pivotable relative to the camera body between a storage position in which the two lenses are concealed within the camera body and respective use positions in which the two lenses alternatively are located for picture-taking.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
A photographic camera comprising a camera body and an objective lens carrier, is characterized in that: a pair of alternative picture-taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for movement of the lens carrier unitarily with said shorter and longer focal length lenses relative to the camera body between a storage position in which neither of said shorter and longer focal length lenses are located to take a picture and respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
Claim 2
Dependent Claim
128 words
A photographic camera comprising a camera body and an objective lens carrier, is characterized in that: a pair of alternative picture-taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for movement of the lens carrier unitarily with said shorter and longer focal length lenses relative to the camera body between a storage position in which neither of said shorter and longer focal length lenses are located to take a picture and respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
Claim 3
Dependent Claim
66 words
A photographic camera as recited in claim 1, wherein said lens carrier includes lens mounting means for locating said shorter and longer focal length lenses to conceal them within said camera body when the lens carrier is in its storage position and to reveal them outside the camera body at least alternatively when the lens carrier is in its shorter and longer focal length use positions.
Claim 4
Dependent Claim
84 words
A photographic camera as recited in claim 1, wherein said support means includes integral means for retracting said lens carrier unitarily with said shorter and longer focal length lenses at least part way into said camera body when the lens carrier is in its storage position and for extending the lens carrier unitarily with said shorter and longer focal length lenses respective lesser and greater distances from the camera body when the lens carrier is in its shorter and longer focal length use positions.
Claim 5
Dependent Claim
26 words
A photographic camera as recited in claim 1, wherein respective shutters are secured to said lens carrier inward of said shorter and longer focal length lenses.
Claim 6
Dependent Claim
75 words
A photographic camera as recited in claim 1, wherein said lens carrier is folded unitarily with said shorter and longer focal length lenses at least part way into said camera body when the lens carrier is in its storage position and is unfolded unitarily with said shorter and longer focal length lenses at least part way out of the camera body when the lens carrier is in its shorter and longer focal length use positions.
Claim 7
Dependent Claim
36 words
A photographic camera as recited in claim 5, wherein said lens carrier is extended lesser and greater distances from said camera body when the lens carrier is in its shorter and longer focal length use positions.
Claim 8
Dependent Claim
46 words
A photographic camera as recited in claim 6, wherein said support means includes integral means for pivoting the lens carrier eccentrically with respect to the camera body as the lens carrier is moved between its storage position and its shorter and longer focal length use positions.
Claim 9
Dependent Claim
55 words
A photographic camera as recited in claim 1, wherein said support means includes integral means for moving said lens carrier inwardly and outwardly of said camera body unitarily with said shorter and longer focal length lenses as the lens carrier is moved between its storage position and its shorter and longer focal length use positions.
Claim 10
Dependent Claim
106 words
A photographic camera comprising a camera body and an objective lens carrier, is characterized in that: a pair of alternative picture-taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for pivoting the lens carrier unitarily with said shorter and longer focal length lenses relative to the camera body to respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
Claim 11
Dependent Claim
106 words
A photographic camera comprising a camera body and an objective lens carrier, is characterized in that: a pair of alternative picture-taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for pivoting the lens carrier unitarily with said shorter and longer focal length lenses relative to the camera body to respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
Claim 12
Dependent Claim
63 words
A photographic camera as recited in claim 9, wherein said support means includes integral means connecting said camera body and said lens carrier for pivoting the lens carrier unitarily with said shorter and longer focal length lenses relative to the camera body to a storage position in which neither of said shorter and longer focal length lenses are located to take a picture.
Claim 13
Dependent Claim
61 words
A photographic camera as recited in claim 9, wherein said support means includes integral means for moving said lens carrier unitarily with said shorter and longer focal length lenses from inward of said camera body to outward of the camera body as the lens carrier is pivoted from its shorter focal length use position to its longer focal length use position.
Claim 14
Dependent Claim
25 words
A photographic camera as recited in claim 11, wherein said integral means includes a pivot pin connecting said lens carrier eccentrically to said camera body.
Claim 15
Dependent Claim
108 words
A photographic camera comprising a camera body and a lens carrier, is characterized in that: a pair of alternative taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for movement of the lens carrier unitarily with said shorter and longer focal length lenses inwardly and outwardly of the camera body to respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
Claim 16
Dependent Claim
108 words
A photographic camera comprising a camera body and a lens carrier, is characterized in that: a pair of alternative taking lenses having respective shorter and longer focal lengths are secured to said lens carrier to permit movement of the lens carrier unitarily with said shorter and longer focal length lenses; and support means connects said camera body and said lens carrier for movement of the lens carrier unitarily with said shorter and longer focal length lenses inwardly and outwardly of the camera body to respective shorter and longer focal length use positions in which the shorter and longer focal length lenses alternatively are located to take a picture.
