Abstract
An injection device (1) with an End-of-Content mechanism. The End-of-Content mechanism comprises a track (91) and a track follower each coupled directly or indirectly to the housing and the dose setting member (20). When setting a dose, the housing and the dose setting member is rotated relatively to each other thereby also rotating the track-follower in the track a distance corresponding to the size of the set dose. This relative rotation is summarized and stored in the position of the track follower in the track. The housing containing the mechanism is preferably equipped with a transparent (71) area through which a user can inspect the position of the track follower in the track and thereby get a visible warning when the drug reservoir in the injection device is about to be emptied.
