Abstract
A media picking mechanism includes a pair of transmission shafts rotating in opposite directions. A housing is mounted around the pair of transmission shafts such that the first transmission shaft and the second transmission shaft are positioned substantially equidistant from a centerline of the housing. During a media picking operation, the rotation of the first transmission shaft of the pair of transmission shafts provides a first moment to the housing and rotation of a second transmission shaft of the pair of transmission shafts provides a second moment to the housing, which is equal and opposite to the first moment such that a net moment on the housing is near zero minimizing twisting of the housing. The two transmission shafts rotating in opposite directions, also results in substantially equal normal force to be applied by the first and second pick tires on the media.
