Abstract
Abstract A self-processing photographic camera includes a box-like housing provided with a lens support door that is hinged to the housing at one end and which supports the camera lens at its opposite end. A collapsible bellows provides a light seal between the door and the housing and permits the door to move between an open position in oblique relation to the casing and a closed position at which the lens end of the door is adjacent the front wall of the casing but extends somewhat forwardly thereof. A novel supplemental door cooperates with the lens support door to releasably retain the latter in its closed position and to protect the camera lens from dirt or accidental damage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A combined lens cover and latch for a photographic camera, the camera including a body portion, a lens, and a door mounted on the body portion for supporting and pivoting the lens between open and closed positions, said cover and latch comprising: a first element movable from a first position to a second position to engage the door and effect pivoting of the lens from its closed position to its open position, said first element being returned from its second position to its first position in response to movement of the lens to its closed position; a second element coupled to and movable with said first element to cover the lens when said first element is in its first position and the lens is in its closed position, said second element latching the lens in its closed position when covering the lens; and a third element coupled to said first and second elements to move said first element from its first position to its second position.
Claim 2
Dependent Claim

A combined lens cover and latch for a photographic camera, the camera including a body portion, a lens, and a door mounted on the body portion for supporting and pivoting the lens between open and closed positions, said cover and latch comprising: a first element movable from a first position to a second position to engage the door and effect pivoting of the lens from its closed position to its open position, said first element being returned from its second position to its first position in response to movement of the lens to its closed position; a second element coupled to and movable with said first element to cover the lens when said first element is in its first position and the lens is in its closed position, said second element latching the lens in its closed position when covering the lens; and a third element coupled to said first and second elements to move said first element from its first position to its second position.
Claim 3
Dependent Claim
77 words
A folding camera comprising: a. a generally rectangular boxlike housing having a generally flat front wall surface surrounding a forwardly facing recess in said housing, said recess including an end portion; b. a lens; c. a lens support door having a generally flat front face and including an end wall member supporting said lens; d. hinge means pivotally connecting the end of said lens support door opposite said end wall member to said housing for movement between
Claim 4
Dependent Claim

A folding camera comprising: a. a generally rectangular boxlike housing having a generally flat front wall surface surrounding a forwardly facing recess in said housing, said recess including an end portion; b. a lens; c. a lens support door having a generally flat front face and including an end wall member supporting said lens; d. hinge means pivotally connecting the end of said lens support door opposite said end wall member to said housing for movement between
Claim 5
Dependent Claim
105 words
a closed position in which said flat front face of said lens support door is located in acute angular relation to said front wall surface of said housing with said end wall member of said lens support door being partially received in said recess but extending forwardly beyond said front wall surface and with said end portion of said recess extending beyond said end wall member of said lens support door; e. a collapsible bellows connecting said lens support door with said housing; f. a supplemental door partially received within said end portion of said recess, said supplemental door being pivotally supported for movement between
Claim 6
Dependent Claim
105 words
a closed position in which said flat front face of said lens support door is located in acute angular relation to said front wall surface of said housing with said end wall member of said lens support door being partially received in said recess but extending forwardly beyond said front wall surface and with said end portion of said recess extending beyond said end wall member of said lens support door; e. a collapsible bellows connecting said lens support door with said housing; f. a supplemental door partially received within said end portion of said recess, said supplemental door being pivotally supported for movement between
Claim 7
Dependent Claim
166 words
an inoperative position in which said supplemental door is located beyond the path of movement of said end wall member of said lens support door, said end wall member of said lens support door and said supplemental door including cooperating latch means adapted to retain said lens support door in said closed position as long as said supplemental door is in said operative position; g. spring means for resiliently retaining said supplemental door in said operative position; h. an operating member located on said supplemental door at an accessible position within said end portion of said recess and adapted to be moved rearwardly by finger pressure to move said supplemental door from said operative position to said inoperative position; and i. a separating wall dividing said end portion of said recess into a relatively small chamber accommodating said operating member of said supplemental door and a substantially larger chamber that provides a gripping structure by which the corresponding end of said camera can be conveniently grasped.
