A mechanism which greatly reduces the number of components to be manufactured and assembled, and incorporates a kinetic energy storage system into a printing arm-stylus arrangement, and by which incorporation, stored or resilient energy is utilized to provide the stylus with an initial velocity greater than zero with rebounding from impaction with a surface or the like. An auxiliary mass is resiliently or spring-related to the stylus on the one hand, and resiliently or spring-related to a cantilevered beam on the other hand. The printing arm and stylus are caused to rotate towards and from an impacting surface by means of a torque produced about a point of rotation for the stylus. A motive source of force, such as armature and electromagnet, pulls and pushes a tension means or rod disposed at a constant radius from such point of rotation, such means operatively connected to the printing arm and stylus. Superior performance in terms of speed of and time saved in motion of the stylus is achieved.
A print mechanism constructed from and included within a flat piece of material, said flat piece of material including
A means which includes an element for impacting on a surface,
A print mechanism constructed from and included within a flat piece of material for converting forward velocity of an impacting element in said print mechanism to an augmented reverse velocity in a bounced direction for the element, comprising
The print mechanism of claim 1 or claim 2 or claim 3 or claim 4 or claim 5 or claim 7 or claim 8 or claim 9 or claim 17 or claim 20 wherein said flat piece of material comprises stainless steel.
