Abstract
Abstract A compact folding camera of the self-developing type including an open ended chamber for receiving a film assemblage. A lens housing section and a processing housing section are mounted in closing relation to the open end of the chamber when the camera is folded. Both are movable, in opposite directions, to expose the open end of the chamber to allow a film assemblage to be inserted into or withdrawn from the chamber through the open end.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
Photographic apparatus comprising: a first housing section including means defining a chamber for receiving a film assemblage, said chamber having an open end through which a film assemblage is adapted to be inserted; a second housing section, including lens means, and a third housing section, including processing means, extending forwardly of said first housing section in closing relation to said open end, said second housing section being spaced from said open end and said processing means being positioned to extend into said space; and means coupling said second and third housing sections to said first housing section for movement in opposite directions to expose said open end thereby permitting a film assemblage to be inserted into or withdrawn from said chamber through said open end.
Claim 2
Dependent Claim
125 words
Photographic apparatus comprising: a first housing section including means defining a chamber for receiving a film assemblage, said chamber having an open end through which a film assemblage is adapted to be inserted; a second housing section, including lens means, and a third housing section, including processing means, extending forwardly of said first housing section in closing relation to said open end, said second housing section being spaced from said open end and said processing means being positioned to extend into said space; and means coupling said second and third housing sections to said first housing section for movement in opposite directions to expose said open end thereby permitting a film assemblage to be inserted into or withdrawn from said chamber through said open end.
Claim 3
Dependent Claim
31 words
Photographic apparatus as defined in claim 1 wherein said processing means are located in position for cleaning when said second and third housing sections are positioned to expose said open end.
Claim 4
Dependent Claim
36 words
Photographic apparatus as defined in claim 1 wherein said chamber has a tapered configuration in cross section substantially conforming to that of a film assemblage for insuring selective insertion of the film assemblage into said chamber.
Claim 5
Dependent Claim
65 words
Photographic apparatus as defined in claim 1 further including optical means located in a first plane and forming a portion of said chamber and said chamber is configured and dimensioned to restrict insertion of a film assemblage through said open end to a plane substantially parallel with said first plane thereby substantially reducing the possibility of the film assemblage contacting said optical means during insertion.
Claim 6
Dependent Claim
38 words
Photographic apparatus as defined in claim 1 wherein said third housing section includes a recessed portion for receiving said second housing section when said second and third housing sections are in said closing relation to said open end.
Claim 7
Dependent Claim
49 words
Photographic apparatus as defined in claim 1 wherein said third housing section further includes a surface located in overlying relation to said lens means to form a protective cover for said lens means when said second and third housing sections are in said closing relation to said open end.
Claim 8
Dependent Claim
48 words
Photographic apparatus as defined in claim 6 wherein said second housing section further includes shutter release means and said third housing section includes means for preventing actuation of said shutter release means when said second and third housing sections are in said closing relation to said open end.
