Abstract
A camera winding mechanism for advancing the film and loading the shutter has a stop mechanism to prevent over rotation of the film sprocket shaft. In one embodiment a frictional brake ring mounted on the shaft engages a protrusion on the mirror charge lever to inhibit rotation of the sprocket when the film advance lever has reached the limit of travel. In a second embodiment, a pawl element is used to engage the protrusion.
