Claim:
1. Medicament delivery device comprising: a generally elongated tubular housing having opposite proximal and distal parts; a needle shield sleeve slidably and coaxially arranged inside the housing and wherein a proximal part of said sleeve protrudes a distance outside the proximal part of the housing; a syringe carrier mechanism comprising a syringe carrier slidably and coaxially arranged within the needle shield sleeve, a syringe comprising a stopper, a medicament and a needle, wherein said syringe is coaxially arranged within said syringe carrier; a first activator member slidably and coaxially arranged within the housing and connected to said needle shield sleeve; a second activator member slidably and coaxially arranged within the first activator member; a drive mechanism slidably and coaxially arranged within the second activator member and releasably connected to the second activator member, wherein said drive mechanism is adapted to accumulate a drive force for moving said syringe carrier mechanism in a first step for penetrating the needle into an injection site and to move said stopper in a second step for expelling the medicament through the needle; wherein said second activator member is arranged with an information means arranged to cooperate with corresponding interacting means arranged on the distal part of the elongated tubular housing; wherein the second activator member is forced to be displaced towards the distal part of the elongated tubular housing for producing audible, visual and/or tactile feedback to a user about an injection.
