Abstract

Abstract Electronic flash incorporated camera including a camera body having a lens, a case for the camera body, and a lens protective cover slidably mounted on the case. The cover is slidable between a closed position in which the cover covers the lens, and a retracted position in which the lens is exposed. An electronic flash emission member is mounted on the cover, and the emission member is positioned so as to project beyond the contour of the camera case when the cover is in the retracted position.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 110 words
An electronic flash incorporated camera, comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover having an electronic flash emission member, said cover being slidably mounted on the front of said case, said cover being slidable between a closed position in which said cover covers said lens, and a retracted position in which said lens is exposed; first guide means for guiding said protective cover; second guide means for guiding said emission member; said emission member being positioned so as to project beyond said external contour of said case when said cover is in said retracted position.
Claim 2
Dependent Claim 110 words
An electronic flash incorporated camera, comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover having an electronic flash emission member, said cover being slidably mounted on the front of said case, said cover being slidable between a closed position in which said cover covers said lens, and a retracted position in which said lens is exposed; first guide means for guiding said protective cover; second guide means for guiding said emission member; said emission member being positioned so as to project beyond said external contour of said case when said cover is in said retracted position.
Claim 3
Dependent Claim 24 words
A camera as claimed in claim 1, wherein said first guide means guides said protective cover between said closed position and said retracted position.
Claim 4
Dependent Claim 40 words
A camera as claimed in claim 2, wherein said first guide means comprises guide rails provided on said protective cover and retainers mounted on said case, said guide rails and said retainers being slidably engageable with respect to each other.
Claim 5
Dependent Claim 54 words
A camera as claimed in claim 3, wherein each of said retainers includes a retainer abutment face, and said protective cover includes a corresponding protective cover abutment face, said retainer and protective cover abutment faces being abutingly engageable to stop sliding movement of said protective cover when said protective cover reaches said retracted position.
Claim 6
Dependent Claim 32 words
A camera as claimed in claim 4, wherein each said retainer includes an inclined surface extending from said respective abutment faces for facilitating engagement of said protective cover with each said retainer.
Claim 7
Dependent Claim 28 words
A camera as claimed in claim 1, wherein said second guide means guides said emission member as said protective cover is moved between said closed and retracted positions.
Claim 8
Dependent Claim 41 words
A camera as claimed in claim 6, wherein said second guide means includes guide edges provided in said case and a groove formed in said emission member, said groove and said guide edges being slidably engageable with respect to each other.
Claim 9
Dependent Claim 29 words
A camera as claimed in claim 7, wherein said emission member is mounted in a housing formed integrally with said protective cover, said groove being formed in said housing.
Claim 10
Dependent Claim 35 words
A camera as claimed in claim 6, wherein an aperture is provided in said case for electrically connecting said emission member to an emission member control switch, said guide edges being defined by said aperture.
Claim 11
Dependent Claim 180 words
An electronic flash incorporated camera comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover slidably mounted on the front of said case, and being slidable between a closed position in which said cover covers said lens and a retracted position in which said lens is exposed; lens protective cover position indicating means mounted on said lens protective cover for indicating whether said protective cover is in said closed or said retracted position, said indicating means comprising an indicating member which is projectable beyond said external contour of said case when said cover is moved to said retracted position, said indicating means including an electronic flash emission member which is movable away from said lens upon movement of said protective cover from said closed position to said retracted position; first guide means for guiding said protective cover between said closed and retracted positions; second guide means for guiding said lens protective cover position indicating means when said protective cover is moved between said closed and retracted positions.
Claim 12
Dependent Claim 180 words
An electronic flash incorporated camera comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover slidably mounted on the front of said case, and being slidable between a closed position in which said cover covers said lens and a retracted position in which said lens is exposed; lens protective cover position indicating means mounted on said lens protective cover for indicating whether said protective cover is in said closed or said retracted position, said indicating means comprising an indicating member which is projectable beyond said external contour of said case when said cover is moved to said retracted position, said indicating means including an electronic flash emission member which is movable away from said lens upon movement of said protective cover from said closed position to said retracted position; first guide means for guiding said protective cover between said closed and retracted positions; second guide means for guiding said lens protective cover position indicating means when said protective cover is moved between said closed and retracted positions.
Claim 13
Dependent Claim 145 words
An electronic flash incorporated camera, comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover slidably mounted on said case and being slidable between a closed position in which said cover covers said lens, and a retracted position in which said lens is exposed, said cover having a lens cover portion and an electronic flash emission member portion having an electronic flash emission member mounted thereto, said electronic flash emission member portion being located within said external contour in said closed position, said electronic flash emission member being slidable in the same direction as said lens cover portion when said lens cover portion moves between said closed and retracted positions, said electronic flash emission member portion projecting beyond said external contour of said case when said cover is in said retracted position.
Claim 14
Dependent Claim 145 words
An electronic flash incorporated camera, comprising: a camera body having a lens; a case for said camera body, said case having an external contour; a lens protective cover slidably mounted on said case and being slidable between a closed position in which said cover covers said lens, and a retracted position in which said lens is exposed, said cover having a lens cover portion and an electronic flash emission member portion having an electronic flash emission member mounted thereto, said electronic flash emission member portion being located within said external contour in said closed position, said electronic flash emission member being slidable in the same direction as said lens cover portion when said lens cover portion moves between said closed and retracted positions, said electronic flash emission member portion projecting beyond said external contour of said case when said cover is in said retracted position.
