Abstract
An impact-type recording apparatus is disclosed. The apparatus of this invention comprises: a platen for supporting a recording medium; hammer means guided for reciprocal movement between a strike position where the hammer means strikes a character element to force it against an inked ribbon and a recording medium supported on the platen and a stand-by position where the hammer means is kept apart from the platen; energizing means for generating a force acting to move the hammer means from the stand-by position to the strike position; and control means for actuating the energizing means while the hammer means is being moved from the stand-by position to the strike position for striking purposes and while the hammer means is being moved from the strike position to the stand-by position for returning purposes. This construction enables the high-speed operation of the printing mechanism to be carried out with a low level of noise generation.
