The injector further comprises an electronic capturing system for capturing data representing a dose of drug to be expelled, and a switch (38) for starting initialization of the data capture system, the switch being actuated when the actuation member is positioned in its intermediate position. A spring (34) provides a biasing force against movement of the actuation member between its initial and intermediate position. Thereby the electronic data capturing system is allowed to initialize during the actuation member's movement between the intermediate and the actuated position. ## Claims ### Claim 1 A drug delivery system, comprising: expelling device for expelling a dose of drug from a reservoir, an electronically controlled capturing system for capturing data representing a property related to the amount of drug expelled from a reservoir by the expelling means, switch device for starting initialization of the capturing system, a release member for releasing or driving the expelling means and adapted to be moved between: an initial position, and an actuated position in which the expelling means is released or driven, an actuation member adapted to be moved by a user between: an initial position, an intermediate position in which the switch means is actuated to start initialization of the capturing system, and an actuated position in which the release member is actuated, actuation biasing means providing a biasing force against movement of the actuation member between its initial and intermediate position, whereby the capturing system is allowed to initialize during the actuation member's movement between the intermediate position and the actuated position. ### Claim 2 (depends on 1) A drug delivery system as in claim 1, wherein the expelling device can be set to deliver a user selected dose size, the selected dose size being represented by indicia which can be captured by a detection device. ### Claim 3 (depends on 2) A drug delivery system as in claim 2, wherein the expelling device comprises a rotatable member on the surface of which indicia are arranged, the indicia representing the set dose size being positioned at a given capture position allowing capture thereof by the detection device. ### Claim 4 (depends on 3) A drug delivery system as in claim 3, wherein the rotatable member rotates during expelling of a set dose, the indicia at a given point in time representing, directly or indirectly, the expelled dose. ### Claim 5 (depends on 3) A drug delivery system as in claim 3, wherein the indicia is a numerical value which can be read or captured by both a user and the detection device. ### Claim 6 (depends on 3) A drug delivery system as in claim 3, wherein two indicia are provided on one or two rotatable members, one indicia being readable by a user, the other being readable by the detection device. ### Claim 7 (depends on 1) A drug delivery system as in claim 1, wherein the actuation member during movement between its intermediate and actuated position directly or indirectly is brought in contact with the release member. ### Claim 8 (depends on 1) A drug delivery system as in any of claim 1, wherein the biasing device comprises a spring acting on the actuation member. ### Claim 9 (depends on 8) A drug delivery system as in claim 8, wherein the spring has a stationary portion being supported by a component of the system which does not move during setting and expelling of a dose of drug. ### Claim 10 (depends on 1) A drug delivery system as in claim 1, further comprising: release biasing device providing a biasing force against movement of the release member between its initial and actuated position, wherein the biasing device are configured to provide a step-formed increase in the biasing force acting on the actuation member during movement between its intermediate and actuated position. ### Claim 11 (depends on 1) A drug delivery system as in claim 1, comprising a housing in which the expelling device, the release member, the actuation member, the electronically controlled capturing system, the switch device, and the actuation biasing device are arranged. ### Claim 12 (depends on 1) A drug delivery system as in claim 1, comprising a drug delivery unit and a data capture unit releasably attachable to each other, the drug delivery unit comprising: the expelling device, and the release member, the data capture unit comprising: the actuation member (130), the electronically controlled capturing system, the switch device, and the actuation biasing device. ### Claim 13 (depends on 1) A drug delivery system as in claim 1, comprising a drug reservoir. ### Claim 14 (depends on 1) A drug delivery system as in claim 1, the system being configured to receive a replaceable drug reservoir in the form of a drug cartridge.
