摘要:
Apparatus for making flying impressions of type symbols by the use of two or more side-by-side impact wheels extending in planes parallel of the plane of a disklike-type carrier and spaced laterally therefrom. A rocking lever pivoted intermediate its ends forms the printing hammer and is actuated by coupling members independently engaged between the teeth of the rotating impact wheels. The impact wheels have teeth spaced one-half pitch apart, where two wheels are used. The teeth correspond to the characters on the type carrier, and each impact wheel has onehalf the number of teeth as the number of characters on the type carrier. The impact wheels are coupled to the type carrier to rotate therewith. The coupling members are actuated by electromagnets energized by an energy storer for the printing energy, and are selectively engaged between the teeth of the thrust wheels by the electromagnets, to actuate the rocking lever to effect the high-speed making of flying impressions of selected-type symbols. In a modified form the rocking lever moves between two stops and engages a vertically guided hammer, and moves the hammer radially to strike a recording medium against the type carrier and returns the hammer on its return stroke.
