Abstract
A single-use camera which includes: a film winding knob, capable of rotating in the winding direction, for winding a film so as to feed the film frame by frame; a reversion-preventing member, having an engagement with the film winding knob, for preventing the film winding knob from rotating in the opposite direction to the winding direction; a releasing member for releasing the engagement of the reversion-preventing member with the film winding knob when the film is wound by the film winding knob so that the noise, generated from the reversion-preventing member, is prevented.
