Abstract
A fail-safe film prewinder for a camera. The prewinder has a mode switch which can be changed over by switching to a photographing mode upon completion of a prewinding mode in which a film is continuously pulled or prewound from a film cartridge loaded in the camera. When the mode switch is in the prewinding mode position while a shutter release button is being operated, a film transport motor is rotated in the direction to prewind the film again after an interruption of the prewinding mode.
