Abstract
A printing mechanism is described comprising a plurality of type carriers (12, 34) which on their outer peripheral face carry in one region printing types and in another region indicator types (44). The printing types can be brought into a printing position by turning the type carriers (12, 34). A setting means (32, 20, 24) including an actuating knob (32) can be brought into a drive connection with each of the type carriers (12, 34) for rotation thereof. Stop means (100, 102, 104, 106, 110) limit the turning travel of the type carriers (12, 34). Detent elements (96) hold the actuating knob against rotation relative to the type carrier (12, 34) which is in drive connection with the setting means (32, 20, 24), with a detent moment governed by the spring hardness of the detent elements. The spring hardness and thus the detent moment are determined so that when a moment is applied greater than the detent moment, rotation is permitted between the actuation knob and the type carrier, and when a moment is applied, there is no relative rotation between the actuation knob and the type carrier, and the type carrier is turned.
