ABSTRACT:
A carriage drive apparatus comprising a carriage, a drive mechanism to drive the carriage in one direction, a shaft rotatable at a constant speed, an overrunning clutch mounted on the shaft, and at least one lever connecting the clutch and the carriage, the lever pivoting about the shaft. The arrangement is such that on movement of the carriage in the one direction, the lever is moved, but is prevented from rotating about the shaft at greater than the given speed by the overrunning clutch. A plurality of levers may be employed. The apparatus is particularly useful for providing controlled deceleration during the return scan of a scanning lamp carriage of a reproducing machine.
