Abstract

Abstract A photographic camera has a barrier which is disposed between the camera body and a decorative front cover to be movable between a closing position where it covers a taking lens of the camera and an opening position where it opens the taking lens through an opening formed in the front cover. The barrier is provided with an opening which is brought into alignment with the taking lens and the opening in the front cover when the barrier is moved to the opening position and has a smaller diameter than the opening in the front cover. An anti-flare pattern of recessed portions and protruded portions is formed on the outer surface of the barrier around the opening.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 125 words
A photographic camera having a barrier which is disposed between the camera body and a decorative front cover, said barrier movable between a closed position where it covers a taking lens of the camera and an open position where it exposes the taking lens through an opening formed in the front cover, characterized in that: said barrier is provided with an opening which is brought into alignment with the taking lens and the opening in the front cover when the barrier is moved to the open position said opening of said barrier having a smaller diameter than the opening in the front cover, and an anti-flare pattern comprising recessed portions and protruding portions is formed on the outer surface of the barrier around the opening.
Claim 2
Dependent Claim 125 words
A photographic camera having a barrier which is disposed between the camera body and a decorative front cover, said barrier movable between a closed position where it covers a taking lens of the camera and an open position where it exposes the taking lens through an opening formed in the front cover, characterized in that: said barrier is provided with an opening which is brought into alignment with the taking lens and the opening in the front cover when the barrier is moved to the open position said opening of said barrier having a smaller diameter than the opening in the front cover, and an anti-flare pattern comprising recessed portions and protruding portions is formed on the outer surface of the barrier around the opening.
Claim 3
Dependent Claim 20 words
A photographic camera as defined in claim 1 in which said opening in the barrier flares toward the taking lens.
Claim 4
Dependent Claim 29 words
A photographic camera as defined in claim 1 wherein said anti-flare pattern comprises a plurality of alternating annular recessions and protrusions arranged concentrically with the opening of the barrier.
Claim 5
Dependent Claim 16 words
A photographic camera as defined in claim 1 wherein said anti-flare pattern comprises a mosaic pattern.
Claim 6
Dependent Claim 16 words
A photographic camera as defined in claim 1 wherein said anti-flare pattern comprises a satin pattern.
Claim 7
Dependent Claim 28 words
A photographic camera as defined in claim 1 wherein the barrier moves between the open and closed positions by sliding in a plane parallel to the front cover.
Claim 8
Dependent Claim 174 words
A photographic camera comprising: a camera body including a front housing with a lens opening therein; a camera operating mechanism in the camera body; an image forming lens mounted in the camera body, facing the front housing; and a barrier disposed between the image forming lens and the front housing and having a front surface facing the front housing, said barrier having an opening therein which is smaller than the lens opening in the front housing; barrier moving means for moving said barrier between a closed position where it covers the lens and an open position where the opening in the barrier is aligned with the image forming lens and the lens opening of the front housing to expose the lens; wherein said front surface of said barrier has an anti-flare pattern arranged around the opening of the barrier, such that in the open position said anti-flare pattern is exposed through the lens opening of the front housing to outwardly reflect a peripheral portion of light entering through the front housing to prevent flare.
Claim 9
Dependent Claim 174 words
A photographic camera comprising: a camera body including a front housing with a lens opening therein; a camera operating mechanism in the camera body; an image forming lens mounted in the camera body, facing the front housing; and a barrier disposed between the image forming lens and the front housing and having a front surface facing the front housing, said barrier having an opening therein which is smaller than the lens opening in the front housing; barrier moving means for moving said barrier between a closed position where it covers the lens and an open position where the opening in the barrier is aligned with the image forming lens and the lens opening of the front housing to expose the lens; wherein said front surface of said barrier has an anti-flare pattern arranged around the opening of the barrier, such that in the open position said anti-flare pattern is exposed through the lens opening of the front housing to outwardly reflect a peripheral portion of light entering through the front housing to prevent flare.
Claim 10
Dependent Claim 37 words
A photographic camera as defined in claim 7 in which said opening in the barrier has a varying diameter which is greater at a point closer to the lens than at a point farther from the lens.
Claim 11
Dependent Claim 29 words
A photographic camera as defined in claim 7 wherein said anti-flare pattern comprises a plurality of alternating annular recessions and protrusions arranged concentrically with the opening of the barrier.
Claim 12
Dependent Claim 16 words
A photographic camera as defined in claim 7 wherein said anti-flare pattern comprises a satin pattern.
Claim 13
Dependent Claim 42 words
A photographic camera as defined in claim 7 wherein said barrier moving means comprises means for slidably holding the barrier in a plane parallel to the front cover so that the barrier slides between the open and closed positions within said plane.
Claim 14
Dependent Claim 146 words
A photographic camera having a barrier which is disposed between the camera body and a front cover, said barrier movable between a closed position where it covers a lens of the camera and an open position where it exposes the lens through an opening formed in the front cover, characterized in that: said barrier has an opening which is aligned with the taking lens and the opening in the front cover when the barrier is moved to the open position, said opening of said barrier having a smaller diameter than the opening in the front cover, wherein an anti-flare pattern comprising recessed portions and protruding portions is formed on the outer surface of the barrier around the opening, and said opening in the barrier has a varying diameter which is greater at a point closer to the lens than at a point farther from the lens.
Claim 15
Dependent Claim 146 words
A photographic camera having a barrier which is disposed between the camera body and a front cover, said barrier movable between a closed position where it covers a lens of the camera and an open position where it exposes the lens through an opening formed in the front cover, characterized in that: said barrier has an opening which is aligned with the taking lens and the opening in the front cover when the barrier is moved to the open position, said opening of said barrier having a smaller diameter than the opening in the front cover, wherein an anti-flare pattern comprising recessed portions and protruding portions is formed on the outer surface of the barrier around the opening, and said opening in the barrier has a varying diameter which is greater at a point closer to the lens than at a point farther from the lens.
Claim 16
Dependent Claim 29 words
A photographic camera as defined in claim 12 wherein said anti-flare pattern comprises a plurality of alternating annular recessions and protrusions arranged concentrically with the opening of the barrier.
Claim 17
Dependent Claim 16 words
A photographic camera as defined in claim 12 wherein said anti-flare pattern comprises a satin pattern.
Claim 18
Dependent Claim 28 words
A photographic camera as defined in claim 12 wherein the barrier moves between the open and closed positions by sliding in a plane parallel to the front cover.
