摘要： A ruggedized typebar guide is disclosed comprising two spaced pivots and two guide dogs rotatably mounted to the pivots with each guide dog having spaced opposing cam surfaces respectively disposed along opposing sides of a typebar flight path. Shock absorbing means are provided permitting limited movement of the pivots in a direction substantially parallel the flight path upon rotation of the guide dogs. Means are also provided for rotating the guide dogs about the movable pivots upon passage of a typebar between the guide dogs along the typebar flight path to converge the two opposing cam surfaces towards one another a predetermined distance within the flight path to center the typebar.
