Abstract
Mounted on a horizontal shaft 1 extending along surfaces of a film f are sprocket wheels 2 each having three tooth pairs 2a adapted to engage with perforations on the film. The tooth pairs 2a are angularily spaced apart from each other by 120 degrees around a periphery of the sprocket wheel 2. A triangular cam 11 is attached on one end of a horizontal shaft 7 rotatable in unison with the shaft 1. A lever 17 is attached to a horizontal shaft 15 carrying a cam follower 16 rotatable in unison with the rotation of the cam 11. A projection 20 which reciprocates registration pins 22 for engagement with and disengagement from the perforations g of the film f is fitted into an elongated slot 17a of the lever 17. A switching lever 14 is provided for displacement of the shaft 7 into a position where the shaft 7 is prevented from rotating even when the horizontal shaft 1 is rotated.
