Abstract
Abstract A camera body has mounted on it a lens mount which is pivotable relative to the camera between an operative and an inoperative position. A mechanism in the camera is activated and transports film from the camera film chamber through the camera during movement of the lens mount from one to the other (or from the other to the one) of the aforementioned positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
In a camera, particularly an instant-picture camera, a combination comprising a camera body provided with a film chamber for film to be exposed; a rigid hollow lens mount connected to said body and pivotable relative thereto about a pivot axis between a camera-opening and a camera-closing position; biasing means permanently biasing said lens mount towards said camera-opening position; locking means for locking said lens mount in said camera-closing position; transporting means for transporting film out of said chamber, including a pair of nip rollers; means for operating said transporting means and linking said mount with at least one of said nip rollers to rotate the same only in response to movement of said lens mount to said camera-closing position, including a gear segment turnable about said axis in unison with said lens mount, and a toothed belt driven by said gear segment and transmitting motion to said one nip roller; and means cooperating with said gear segment and operative, when said gear segment is pivoted, for cocking a shutter mechanism of the camera.
Claim 2
Dependent Claim
