<p>A displacement magnifying mechanism, comprising:- (a) a base member (12); (b) an actuator (10) having a free end (10a, 14), a base end (10b) connected to the base member (12), and an actuator axis defined as passing through the free end (10a, 14) and the base end (10b), the actuator (10) having a first state, in which the actuator has a first length along the actuator axis, and a second state, in which the actuator has a second, for example greater, length along the actuator axis; (c) an actuatable member (20, 22, 36); (d) a first resilient leaf member (16, 46), having a first end connected to the free end (10a, 14) of the actuator (10) and a second end connected to the actuatable member (20, 22, 36); (e) a second resilient leaf member (18, 48), having a first end connected to the base member (12), a second end connected to the actuatable member (20, 22, 36), and a broad face facing towards the actuator (10) and confronting a broad face of the first resilient leaf member (16, 46); whereby a change of state of the actuator (10) deforms the first (16, 46) and second (18, 48) resilient leaf members causing the actuatable member (20, 22, 36) to be displaced around an axis perpendicular to the actuator axis and parallel to said broad faces. The mechanism finds application, for example, in a print element.</p> |
