Abstract
In a motor-drive film-winding camera of the type capable of multiexposure, having separate motors for cocking the shutter (or the mirror in a single lens reflex camera), and for film winding, a changeover is provided to switch from normal operation with energization of both motors to a multiexposure mode providing for double exposure operating the shutter cocking motor while the film-winding motor remains idle. Operation is limited to a double exposure since when the latter is completed, the changeover switch is overridden and the system returns to normal operation.
