Abstract
A camera includes a body portion having a cartridge chamber for a film cartridge and a film chamber for a filmstrip, a high energy lever returnable to a cocked position, and a film metering pawl movable in engagement with the filmstrip. The film metering pawl is placed in engagement with the filmstrip to prevent winding of the filmstrip into the cartridge, and released from engagement when the high energy lever is being returned to its cocked position to permit the filmstrip to be wound into the cartridge. The film metering pawl is movable to a film metered position where it is locked and the film advance is disabled.
