1. A medicament delivery device comprising:
a proximal end and a distal end defining a longitudinal axis;
a body;
a button arranged at the proximal end and configured to actuate the medicament delivery device;
a lock ring configured to rotate relative to the body about the longitudinal axis between a first position in which the button is not permitted to move along the longitudinal axis relative to the body, and a second position in which the button is permitted to move along the longitudinal axis relative to the body;
a plurality of first indication elements circumferentially spaced around a first portion of the medicament delivery device; and
a plurality of second indication elements circumferentially spaced around a second portion of the medicament delivery device,
wherein the plurality of first indication elements and the plurality of second indication elements are moveable relative to one another between a first state in which at least one first indication element of the plurality of first indication elements is not axially aligned with at least one second indication element of the plurality of second indication elements, and a second state in which said at least one first indication element of the plurality of first indication elements is axially aligned with said at least one second indication element of the plurality of second indication elements,
wherein the lock ring is configured such that when the lock ring is in the first position, the plurality of first indication elements and the plurality of second indication elements are in the first state, and when the lock ring is in the second position, the plurality of first indication elements and the plurality of second indication elements are in the second state, and
wherein the second portion of the medicament delivery device comprises an indicator ring, wherein the indicator ring and the first portion of the medicament delivery device are rotatable relative to one another, and wherein the indicator ring comprises the plurality of second indication elements which is circumferentially spaced apart around the indicator ring and is separated by a plurality of masking portions configured to mask the plurality of first indication elements, such that:
when the plurality of first indication elements and the plurality of second indication elements are in the first state, each first indication element of the plurality of first indication elements is aligned with a respective one of the plurality of masking portions, such that the plurality of first indication elements is not visible, and
when the plurality of first indication elements and the plurality of second indication elements are in the second state, each first indication element of the plurality of first indication elements is not aligned with a respective one of the plurality of masking portions, such that the plurality of first indication elements is visible.
