Photographic apparatus with through-the-lens view finder

Claim 2

In a motion picture camera, a combination comprising a housing; a picture taking lens; a mount supporting said lens and movable relative to said housing to thereby focus said lens onto subjects lOcated at different distances from said lens; and a through-the-lens view finder arranged to furnish aerial images of subjects, said view finder being mounted in said housing and defining a plurality of real image planes located one behind the other as considered in the direction of entry of light, said view finder including an eyepiece behind said image planes, indications observable through said eyepiece in the region of one of said planes and representing various distances from the subject, index means movably mounted in the region of another of said planes and being observable through said eyepiece, and motion transmitting means interposed between said mount and said index means for moving the latter relative to said indications in response to movement of said mount relative to said housing whereby the indication which is pinpointed by said index means represents the corresponding distance between the subject and said lens.

Claim 3

A combination as defined in claim 1, wherein said motion transmitting means includes a link train.

Claim 4

A combination as defined in claim 1, wherein said lens is movable lengthwise of its axis in response to movement of said mount and said mount is rotatable relative to said housing.

Claim 5

A combination as defined in claim 3, wherein said motion transmitting means comprises cam means provided on said mount, follower means mounted in said housing and arranged to track said cam means, and carrier means movably mounted in said housing and receiving motion from said follower means, said index means being supported by said carrier means.

Claim 6

A combination as defined in claim 4, wherein said carrier means comprises a lever which is pivotable by said follower means.

Claim 7

A combination as defined in claim 4, further comprising means for biasing said carrier means against said follower means.

Claim 8

A combination as defined in claim 4, further comprising means for biasing said follower means against said cam means.

Claim 9

In a photographic apparatus, a combination comprising a housing; a picture taking lens; a mount supporting said lens and rotatable relative to said housing to thereby focus the lens onto subjects located at different distances from the lens, said lens being movable lengthwise of its axis in response to rotation of said mount relative to said housing; and a through-the-lens view finder mounted in said housing and defining a plurality of real image planes, said view finder including an eyepiece behind said image planes, indications observable through said eyepiece in the region of one of said planes and representing various distances from the subject, index means movably mounted in the region of another of said planes and being observable through said eyepiece, and motion transmitting means interposed between said mount and said index means for moving the latter relative to said indications in response to movement of said mount relative to said housing whereby the indication which is pinpointed by said index means represents the corresponding distance between the subject and said lens, said motion transmitting means comprising cam means provided on said mount, follower means mounted in said housing and arranged to track said cam means, and carrier means movably mounted in said housing and receiving motion from said follower means, said index means being supported by said carrier means and said carrier means comprising a first portion which receives motion from said follower means and a second portion supporting said index means, said second portion of said carrier means being movable relative to said first portion of said carrier means to thereby adjust the position of said index means relative to said indications independently of said mount.

Claim 10

In a photographic apparatus, a combination comprising a housing; a picture taking lens; a mount supporting said lens and rotatable relative to said housing to thereby focus the lens onto subjects located at different distances from the lens, said lens being movable lengthwise of its axis in response to rotation of said mount relative to said housing; and a through-the-lens view finder mounted in said housing and defining a plurality of real image planes, said view finder including an eyepiece behind said image planes, indications observable through said eyepiece in the region of one of said planes and representing various distances from the subject, index means movably mounted in the region of another of said planes and being observable through said eyepiece, and motion transmitting means interposed between said mount and said index means for moving the latter relative to said indications in response to movement of said mount relative to said housing whereby the indication which is pinpointed by said index means represents the corresponding distance between the subject and said lens, said motion transmitting means comprising cam means provided on said mount, follower means mounted in said housing and arranged to track said cam means, and carrier means movably mounted in said housing and receiving motion from said follower means, said index means being supported by said carrier means and said carrier means comprising a first portion which receives motion from said follower means and a second portion supporting said index means, said second portion of said carrier means being movable relative to said first portion of said carrier means to thereby adjust the position of said index means relative to said indications independently of said mount.

Claim 11

A combination as defined in claim 8, wherein said carrier means further comprises a deformable third portion connecting said first and second portions.

Claim 12

A combination as defined in claim 1, wherein said one plane is located between said eyepiece and said other plane.
