A camera comprising a film winder rotatable to wind successive exposed imaging areas of a filmstrip onto an exposed film roll, is characterized in that a minor spring source of motion is connected to the film winder to rotate the film winder to wind one exposed imaging area of the filmstrip onto the exposed film roll and can be re-energized to again rotate the film winder to wind another exposed imaging area of the filmstrip onto the exposed film roll, and a major spring source of motion is connected with the minor spring source of motion to re-energize the minor spring source of motion after each exposed imaging area of the filmstrip is wound onto the exposed film roll. Preferably, the major spring source of motion has the capacity to be energized once to re-energize the minor spring source of motion a total number of times at least equal to the total number of successive imaging areas of the filmstrip that are to be exposed.
