ABSTRACT:
A printing mechanism is described comprising a housing (12, 14) in which a plurality of type carriers (20) are disposed which are in a drive connection with coaxially disposed setting wheels (16) each having a center bore. In a space formed by the center bores of the setting wheels a setting shaft (42) is axially displaceable and rotatable. By axial displacement the setting shaft can be brought into a drive connection with each of the setting wheels. On the setting shaft an actuating knob (48) is disposed with the aid of which said shaft can be displaced and turned. In the housing a display indicator means (26, 27, 29) is disposed displaceably parallel to the setting shaft; said means is connected to the setting shaft in such a manner that the latter turns relatively thereto but can be displaced axially only jointly therewith. The display indicator means makes it possible to recognize the type carrier which can be adjusted in the respective axial position of the setting shaft. The connection between the setting shaft and the display indicator means is formed by a substantially circular cap ( 64) which is mounted with a hub (62) on the setting shaft and on the edge of which the display indicator means is secured.
