A single-element type carrier printing mechanism is provided with an element movable to block tangential deflection of the type carrier at printing impact with the platen, is normally disengaged from frictional contact with the type carrier during rotational positioning of the type carrier. The deflection blocking element includes a blocking arm pivotally mounted for free rotation relative to the type carrier, provided with an abutment adapted to act against a blocking surface formed on the type carrier. The blocking arm is also provided with teeth for detent engagement with a tilt detent device which moves the blocking arm from its normally disengaged position into engagement with the blocking surface to prevent impact deflection. |
