<p>A film winder and camera. The film winder has a film transport adapted to move film in two opposed directions in response to rotational inputs in forward and reverse directions. An output unit mechanically engages the film transport. The output unit defines an axis of rotation. An outer winder is coaxial with the output unit. The outer winder is rotatable about the axis in first and second directions of rotation relative to the body. An inner winder is nested in the outer winder. The inner winder is coaxial with the output unit. The inner winder is rotatable about the axis in the first and second directions of rotation independent of the outer winder. Outer and inner clutches are disposed between respective winders and the output unit. The outer clutch couples the outer winder to the output unit during rotation of the outer winder relative to the body in the first direction of rotation. The outer clutch decouples the outer winder from the output unit during rotation of the outer winder relative to the body in the second direction of rotation. The inner clutch couples the inner winder to the output unit during rotation of the inner winder in the second direction of rotation. The inner clutch decouples the inner winder from the output unit during rotation of the inner winder in the first direction of rotation.</p> |
