Claim Text:
1. A drive mechanism for a drug delivery device, comprising: a body having a distal end and a proximal end, spaced apart in the direction of a first axis and a second axis that is parallel to the first axis, a first input member and a second input member, arranged within the body along the first axis and coupled in such a manner that a movement of the first input member along the first axis is converted into a rotational movement of the second input member with respect to the body, a first output member and a second output member, arranged within the body along the second axis and coupled in such a manner that a rotational movement of the first output member is converted into a movement of the second output member along the second axis with respect to the body, the second input member and the first output member being releasably rotationally coupled when the first input member is moved in a distal direction, a pinion member releasably rotationally coupling the second input member and the first output member, a pawl member engaging with the pinion member allowing rotation of the pinion member in only one direction, and a clutch coupling the second input member with the pinion member in a releasable fashion such that the clutch couples the second input member with the pinion member when a force is exerted on the first input member in the distal direction, and the second input member and the pinion member are not coupled when the first input member is being shifted in a proximal direction.
