Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
An impact printing mechanism comprising in combination a frame, a printing surface, a type bearing member, a plurality of elements movably mounted within said frame, said elements coupled to each other with one degree of freedom, said type bearing member being mounted between said printing surface and said movable elements, and means causing a first one of said movable elements to strike said type bearing member and a second one of said movable elements to move simultaneously with said first one of said movable elements and with substantially the same inertial force substantially the same distance in a substantially opposite direction from said first element and away from said type bearing member.
Claim 2
Dependent Claim
112 words

Claim 3
Dependent Claim
21 words
An impact printing mechanism according to claim 1, further comprising means to retract said first movable element from said printing position.
Claim 4
Dependent Claim
16 words
An impact printing mechanism according to claim 2, wherein said striking and retracting means comprise springs.
