发明名称 AUTOMATIC FILM REWINDING CAMERA
摘要 <p>A still camera of the type wherein film is prewound onto a takeup spool within the camera body and thereafter advanced toward and into the film cassette as successive exposures are made includes a final rewind mechanism to prevent the exposed film leader from being positioned in the camera's imaging area. A pair of switches, arranged in series, actuate an electric motor to effect final rewind when sufficient film has been advanced from the takeup spool. One of the switches is actuated responsive to the presence of tensed film on the takeup spool, while the remaining switch is actuated responsive to the presence of film in the camera's imaging area.</p>
