1. A pen-injector for manually administering set doses of a medicament, the injector adapted for accommodating a reservoir comprising a piston movable along a first axis within the reservoir and a medicament to be injected, the pen-injector comprising: a base member;a plunger for driving the piston axially in a distal direction;a driving member axially movable relative to the base member, the driving member movable in a proximal direction relative to an initial position so as to set a dose and manually pushable in a distal direction towards the initial position so as to eject a dose of the medicament; anda gear mechanism providing a gearing between the driving member and the plunger such that when the driving member is moved at a first speed relative to the base member, the plunger is moved at a second speed relative to the base member; wherein at least two of the base member, the plunger and the driving member are pivotally connected to the gear mechanism, and wherein the gear mechanism comprises a lever mechanism coupling a distally directed movement of the driving member with a distally directed movement of the plunger. 2. A pen-injector according to claim 1, wherein the gear mechanism comprises a first connecting member pivotally connected to at least two of the base member, the plunger and the driving member. 3. A pen-injector according to claim 2, wherein the first connecting member is pivotally connected to the base member, the plunger and the driving member. 4. A pen-injector according to claim 1, wherein the gear mechanism comprises a first, second and third connecting member each of which is exclusively connected to one of the base member, the plunger and the driving member. 5. An pen-injector according to claim 4, wherein the second speed is lower than the first speed. 6. A pen-injector according to claim 4, wherein at least one of the second and the third connecting member is at least 20 percent longer than the first connecting member. 7. A pen-injector according to claim 6, wherein at least one of the second and the third connecting member is 50 percent longer than the first connecting member. 8. A pen-injector according to claim 4, wherein the difference in the length of the second and the third connecting member is at least 20 percent. 9.

A pen-injector according to claim 4, wherein the base member comprises a fixed part and a rotatable part, the fixed part being rotationally and translationally retained in relation to a housing of the device, the rotatable part being adapted to rotate relative to the base member about a longitudinal axis of the base member, the rotatable part furthermore being translationally retained in relation to the fixed part. 11. A pen-injector according to claim 10, further comprising a clutch provided between the driving member and the fixed part, said clutch being adapted to be changed between: a coupled position wherein a threaded inner surface of the clutch engages a threaded outer surface of the fixed part such that when the driving member is rotated, the threaded engagement causes the driving member to be moved in a proximal direction, anda decoupled position wherein the threaded inner surface of the clutch disengages the threaded outer surface of the fixed part, so as to allow translational and non-rotational movement between the driving member and fixed part. 12. A pen-injector according to claim 4, wherein the first connecting member is pivotally connected to the base member, the second connecting member is pivotally connected to the driving member, and the third connecting member is pivotally connected to the plunger, and wherein at least one of the second and third connecting members is pivotally connected to the first connecting member. 13. A pen-injector according to claim 12, wherein the first connecting member is pivotally connected to the base member by means of a first pivotal connection, the second member is pivotally connected to the first member by means of a second pivotal connection, and the third member is pivotally connected to the first member by means of a third pivotal connection. 14. A pen-injector according to claim 13, wherein the distance from the third pivotal connection to each of the first and the second pivotal connections is shorter than the distance between the first and the second pivotal connection. 15. A pen-injector according to claim 14, wherein the distance between the third pivotal connection and the first pivotal connection is shorter than the distance between the third pivotal connection and the second pivotal connection. 16. A pen-injector according to claim 14, wherein the distance between the third pivotal connection and the first pivotal connection is longer than the distance between the third pivotal connection and the second pivotal connection. 17. A pen-injector for manually administering set doses of a medicament, the injector adapted for accommodating a reservoir comprising a piston movable along a first axis within the reservoir and a medicament to be injected, the pen-injector comprising: a base member;a plunger for driving the piston axially in a distal direction wherein said plunger comprises a threaded inner surface which is adapted to engage a threaded outer surface of a piston rod, or where said plunger is arranged to cooperate with a pawl and ratchet mechanism which provides for telescopic engagement between said plunger and said piston;a driving member axially movable relative to the base member, the driving member movable in a proximal direction relative to an initial position so as to set a dose and manually pushable in a distal direction towards the initial position so as to eject a dose of the medicament; anda gear mechanism providing a gearing between the driving member and the plunger such that when the driving member is moved at a first speed relative to the base member, the plunger is moved at a second speed relative to the base member; wherein at least two of the base member, the plunger and the driving member are pivotally connected to the gear mechanism, and wherein the gear mechanism comprises a lever mechanism coupling a distally directed movement of the driving member with a distally directed movement of the plunger.
