1. An injector device configurable between a safe state and an operable state, the injector device comprising:
a housing having a distal end and a proximal end;
a medicament cartridge disposed within the housing;
a needle unit comprising a needle, the needle unit being disposed in the distal end of the housing;
a sleeve displaceable along a longitudinal axis of the injector device between a first position in which the sleeve conceals the needle and a second position in which the needle is exposed from an end of the sleeve;
a locking mechanism that prevents displacement of the sleeve when the injector device is in the safe state; and
a button disposed in the proximal end of the housing, the button being configured to switch the injector device between the safe state and the operable state by releasing the locking mechanism to allow displacement of the sleeve when the button is pressed from an initial position into a depressed position during use.
