(54) Backstop for print lever actuator


(57) A print lever actuating mechanism (24) of the electromagnetic type is disclosed. An armature/print lever assembly (23) pivots about the innermost leg (16) of a three-legged stator. A coil (19) for energizing the assembly is disposed about a first one (17) of the outer legs while the other outer leg (15) limits movement of the armature/print lever assembly so as to maintain the air gap (18) between the first outer leg and the armature/print lever assembly (23) constant and fixed. No other mechanisms or adjustments are required to achieve and maintain a desired air gap.
