A photographic roll film camera has a film supply chamber, a spoolless film take-up chamber, a transporting element for transporting the film between these chambers, and a film roll-forming element including a part of the wall of the take-up chamber formed in correspondence to a whole film roll, and a spring-biased guiding lever extending into the take-up chamber and bounding together with the wall a small space for forming a first coil of the film roll so that the initial portion of the film is guided into the small space by the guiding lever and thereafter with increase of the diameter of the film roll during winding of subsequent coils, the guiding lever turns and space for formation of the film roll expands.

Photographic roll film camera

A photographic camera has a shutter and a shutter setting and releasing mechanism which includes an operating member which moves in a predetermined path and direction when released. The camera further includes a time-delay mechanism for the shutter which is arrested by an arresting member when the latter is in its resting position. A coupling element selectively pivots between two positions in one of which it is located outside the path of movement of the operating member while in the other position it engages both the operating member and the arresting member. The coupling component is also mounted for movement in the direction of movement of the operating member when in engagement therewith so that it displaces the arresting member out of the arresting position whereby the time-delay mechanism is released. In a predetermined period of time, the time-delay mechanism activates a sliding member which moves the coupling component out of engagement with the operating member whereby the latter is freed to perform its movement in the aforementioned direction during which the shutter is operated. The camera can be used with or without utilizing the time-delay feature thereof.
