A moving mechanism brings the rotational axis of each driven rotator into alignment with the rotational axis of a drive rotator, which has an engaging face extending along its rotational axis. Each driven rotator has an engageable face extending along the rotational axis of the drive rotator. Rotating the drive rotator while moving the driven rotator, of which the rotational axis is aligned with the rotational axis, toward the drive rotator will bring the engaging face into engagement with the engageable face.
