Adjustment device for a type head designed as a rotary type (German patent specification 1063 6! In the inclination blo. v area arranged rotatably in several rows and columns and detachable with the print head by a rotary movement and connected rotating body and a joint yerbin a pivoting movement can be set and the connection between the rotating shaft and rotating body Lv by an impression movement of the type carrier in xo According to this embodiment, the parts for rotating and tilting the type of head to be printed in the direction of the platen are in the interior, whereby several adjusting members are arranged on the type-hollow type carrier and act to enlarge the type carrier, characterized by it A mass that shows with every movement of the impression that in the position of the impression every me The joint (16, 17) 15 can be accelerated and decelerated several times using any characters. In addition, the dimensioning of the joint of a single member (20) for rotating the type part is spatially limited by the size of the type head carrier (1, 2) and the joint (29, 30). As a result, the Abdruckgeschwindig actuator (24) for pivoting the type carrier speed can only be held in such a size as the Ge (1, 2) on fixed guide rods (23, steering parts in a position sinu, the acceleration upo 28) with the help from in Sohrungen (21, 27) of the input 30 to transmit deceleration forces.
