In a printing device for printers or typewriters a hammer (11) is axially movable between a print position and a rest position. At one end the hammer has an impact surface (12) which acts upon a selected one of a number of type characters disposed along the periphery of a type disc. Preferably at its front end the hammer (11) is connected to a long guide pin (26) which extends mainly perpendicular to the length direction of the hammer and cooperates with a guide slot (27) that extends in the length direction of the hammer. The guide slot is situated at a distance from the hammer which is considerably greater than the diameter of the hammer in its connection point with the guide pin (26). Preferably, the distance is at least four times the diameters. |
