ABSTRACT:
A shuttling printer mechanism suitable for use with dot forming print elements is disclosed. A mechanical linear reciprocable drive apparatus acting as close as possible through the center of percussion of the print head and suspension assembly reciprocates the print head back and forth along a desired print line adjacent to a platen. The drive apparatus utilizes a unique non-circular gear arrangement. The suspension and frame design is adapted to provide print line visibility so that printed characters may be seen as they are formed. The reciprocation drive operates without orthogonal forces. It provides a purely linear drive force so that the machine is free of unwanted vibrations in other planes or axes.
