ABSTRACT:
A cam system to drive an oscillating mirror used to keep the movement images projected onto the moving drum of a xerographic reproduction machine in register. The cam system uses a cam, a cam follower, a drive to move the cam follower to and from a start of scan position while in contact with the cam, and a device to rotate the cam about an axis outside the cam. With this arrangement when the cam is adjusted to alter the path of the cam follower, it is rotated about the center of curvature of the cam follower axis during rotation of the cam so that the cam follower always starts its path from the same start of scan position.
