Abstract
A still camera provides for multiple-frame bursts of sequential exposures while continuously rotating a film take-up spool by creating slack in the filmstrip just upstream of the take-up spool. Subsequent to creating the slack in the take-up spool, a film metering sprocket, which is positively engaged by the filmstrip, is abruptly stopped to arrest motion of the filmstrip so that a frame may be exposed. The exposure time is substantially less than the time required for the take-up spool to wind in the slack. Indexing of the film is accomplished by a pivoted arm which engages both the film and the periphery of a cam rotatable with the metering sprocket. The pivoted arm both creates slack in the film which allows the take-up spool to run continuously and stops rotation of the sprocket to permit exposure of the film.
