Abstract
A one-way winder having a body defining a bifurcated guideway. The guideway has a trunk and first and second branches. The guideway has at least one portal connecting the branches. The director is disposed in the body. The director has an arm-pawl and a guide cam. The director is movable relative to the body in forward and return movements. The guide cam moves along the first branch during the forward movement and along the second branch during the return movement. The guide cam moves unidirectionally along the first branch. An endless ratchet disposed in the body, intrudes into the first branch. The ratchet is driven by the arm-pawl during the forward movement and is spaced apart from the arm-pawl during the return movement. A film advance and camera include the one way winder.
