Abstract
Abstract A photographic camera includes a built-in electronic flash unit which is pivotable with respect to the camera housing. The flash unit pivots between an inactive folded position in which it forms an integrated part of the camera housing to cover a taking lens, and an operative erect position in which it is sufficiently removed from the lens to permit picture-taking substantially without any red-eye effect. The lens is movable along its optical axis to a taking position extended from the camera housing and to a storage position retracted in the housing, in response to pivoting the flash unit to its operative and folded positions, respectively. With the flash unit in its folded position and the lens in its storage position, the camera is relatively compact.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means defining an opening in a front face of said camera housing; means supporting said lens for translation along an optical axis, through said opening, between a storage position retracted in said camera housing and a picture-taking position extended from said front face; and means for translating said lens to its picture-taking and storage positions in response to movement of said flash unit to its operative and inactive positions, respectively.
Claim 2
Dependent Claim
132 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means defining an opening in a front face of said camera housing; means supporting said lens for translation along an optical axis, through said opening, between a storage position retracted in said camera housing and a picture-taking position extended from said front face; and means for translating said lens to its picture-taking and storage positions in response to movement of said flash unit to its operative and inactive positions, respectively.
Claim 3
Dependent Claim
168 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means defining an opening in a front face of said camera housing; means supporting said lens for translation along an optical axis, through said opening, between a storage position retracted in said camera housing and a picture-taking position extended from said front face; means for urging said lens to translate to its picture-taking position; and means supporting said flash unit for pivotal movement over said front face to its inactive position to translate said lens to its storage position and for pivotal movement removed from over said front face to its operative position to permit said urging means to translate said lens to its picture-taking position.
Claim 4
Dependent Claim
168 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means defining an opening in a front face of said camera housing; means supporting said lens for translation along an optical axis, through said opening, between a storage position retracted in said camera housing and a picture-taking position extended from said front face; means for urging said lens to translate to its picture-taking position; and means supporting said flash unit for pivotal movement over said front face to its inactive position to translate said lens to its storage position and for pivotal movement removed from over said front face to its operative position to permit said urging means to translate said lens to its picture-taking position.
Claim 5
Dependent Claim
187 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means supporting said lens for movement between a storage position retracted in said camera housing and a picture-taking position extended from said housing; first means for urging said lens to its picture-taking position; means supporting said flash unit to move said lens to its storage position, against the urging of said first means, as said flash unit is moved to its inactive position; second means for urging said flash unit to its operative position; and means for securing said flash unit in its inactive position to retain said lens in its storage position, said securing means being releasable to permit said second means to move said flash unit to its operative position to permit said first means to move said lens to its picture-taking position.
Claim 6
Dependent Claim
187 words
In a photographic camera of the type provided with a flash unit movable with respect to a camera housing between (i) an inactive position in which said flash unit forms an integrated part of said housing to cover a taking lens and (ii) an operative position in which said flash unit is remote from said lens to permit picture-taking, the improvement comprising: means supporting said lens for movement between a storage position retracted in said camera housing and a picture-taking position extended from said housing; first means for urging said lens to its picture-taking position; means supporting said flash unit to move said lens to its storage position, against the urging of said first means, as said flash unit is moved to its inactive position; second means for urging said flash unit to its operative position; and means for securing said flash unit in its inactive position to retain said lens in its storage position, said securing means being releasable to permit said second means to move said flash unit to its operative position to permit said first means to move said lens to its picture-taking position.
