Abstract
A drive mechanism for an insertion mechanism for an administering device, having a base and a guide track. A slider of the drive mechanism provided on the base in a rotationally fixed manner can be slid along or in the guide track between end positions. A drive wheel is rotatably mounted on the base. A drive track is connected to the slider and has a plurality of drive sections, and an energy source, by means of which the drive wheel can be set into rotation. Upon rotation of the drive wheel, the slider moves along the guide track in the distal direction to a distal end of the guide track and slider is moved along or in the guide track in the proximal direction. The energy source can be coupled to the drive wheel by means of a one-piece or multi-piece transmission element and of an introduction wheel.
