ABSTRACT:
A unidirectional register apparatus includes an input gear mechanism adapted to receive a rotational input from an external source; and a yoke, operatively coupled to the input gear mechanism, and arranged to pivot between a first predetermined position and a second predetermined position in response to a change in direction of the rotational input. Also provided are a first gear mechanism, attached to the yoke, which is arranged to produce a rotational output in the same direction as the rotational input; and a second gear mechanism, also attached to the yoke, which is arranged to produce a rotational output in a direction opposite to the rotational input. An output gear mechanism is provided which is alternately engageable with each of the first and second gear mechanisms. The output gear mechanism engages the first gear mechanism when the yoke is in the first predetermined position, and the output gear mechanism engages the second gear mechanism when the yoke is in the second predetermined position.
