Abstract
Abstract In photographic apparatus having an optical axis, optical modulation assemblies such as shutter and filter assemblies which are selectively moved into and out of the optical axis are shock mounted to reduce stresses in the optical modulation material. In a preferred embodiment, a photographic color printer is provided with subtractive color filters actuated by rotary solenoids. The rotary solenoid has a rotatable mounting plate and a filter carrier is mounted on the mounting plate by means of a shock absorbing layer of dead soft rubber compound. Preferably the filter is also mounted on the filter carrier by means of the same shock absorbing material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
In photographic apparatus having an optical axis; the combination comprising: optical modulation means for optically modulating a beam of light projected along said optical axis; support means for supporting said modulating means for movement between a first position wherein said modulating means is out of said optical axis and a second position wherein said modulating means is in said optical axis; drive means for drivingly moving said support means between said first and second positions; first shock absorbing means for mounting said support means on said drive means; and second shock absorbing means for mounting said optical modulation means to said support means; said first and second shock absorbing means substantially absorbing any shock loads created by movement of said support means between said first and second positions.
Claim 2
Dependent Claim
128 words
In photographic apparatus having an optical axis; the combination comprising: optical modulation means for optically modulating a beam of light projected along said optical axis; support means for supporting said modulating means for movement between a first position wherein said modulating means is out of said optical axis and a second position wherein said modulating means is in said optical axis; drive means for drivingly moving said support means between said first and second positions; first shock absorbing means for mounting said support means on said drive means; and second shock absorbing means for mounting said optical modulation means to said support means; said first and second shock absorbing means substantially absorbing any shock loads created by movement of said support means between said first and second positions.
Claim 3
Dependent Claim
169 words
In a photographic color printer having an optical axis and means for projecting a beam of light along said optical axis, said beam of light having at least first and second color components, the combination comprising: a color filter for filtering said first color component from said beam of light; support means for supporting said color filter for movement between a first position wherein said color filter is out of said optical axis and a second position wherein said color filter is in said optical axis to filter out said first color component from a beam of light projected along said optical axis; drive means for drivingly moving said support means bEtween said first and second positions; first shock absorbing means for mounting said support means on said drive means; and second shock absorbing means for mounting said color filter on said support means; said first and second shock absorbing means substantially absorbing any shock loads created by movement of said support means between said first and second positions.
Claim 4
Dependent Claim
169 words
In a photographic color printer having an optical axis and means for projecting a beam of light along said optical axis, said beam of light having at least first and second color components, the combination comprising: a color filter for filtering said first color component from said beam of light; support means for supporting said color filter for movement between a first position wherein said color filter is out of said optical axis and a second position wherein said color filter is in said optical axis to filter out said first color component from a beam of light projected along said optical axis; drive means for drivingly moving said support means bEtween said first and second positions; first shock absorbing means for mounting said support means on said drive means; and second shock absorbing means for mounting said color filter on said support means; said first and second shock absorbing means substantially absorbing any shock loads created by movement of said support means between said first and second positions.
Claim 5
Dependent Claim
19 words
The combination of claim 2 wherein said first and second shock absorbing means comprises a dead soft rubber-like material.
Claim 6
Dependent Claim
137 words
In a photographic color printer having an optical axis and means for projecting a beam of light along said optical axis, said beam of light having at least first and second color components, the combination comprising: a color filter for filtering said first color component from said beam of light; a filter support member; first shock absorbing material for mounting said filter to said support member; a shaft; a mounting plate mounted on said shaft; second shock absorbing material for mounting said filter support member to said mounting plate; means for mounting said shaft for rotation between a first position wherein said filter is positioned to intercept said beam of light and a second position wherein said filter does not intercept said beam of light; and means for rotating said shaft between said first and second position.
Claim 7
Dependent Claim
137 words
In a photographic color printer having an optical axis and means for projecting a beam of light along said optical axis, said beam of light having at least first and second color components, the combination comprising: a color filter for filtering said first color component from said beam of light; a filter support member; first shock absorbing material for mounting said filter to said support member; a shaft; a mounting plate mounted on said shaft; second shock absorbing material for mounting said filter support member to said mounting plate; means for mounting said shaft for rotation between a first position wherein said filter is positioned to intercept said beam of light and a second position wherein said filter does not intercept said beam of light; and means for rotating said shaft between said first and second position.
