ABSTRACT:
The invention relates to a printing mechanism comprising a plurality of setting wheels (16) which are mounted coaxially on a sleeve (28) and with which type carriers (20) carrying printing types (22) are in a drive connection. In the sleeve (20) a setting shaft (42) is disposed axially displaceably and rotatable therewith. Disposed on the setting shaft is at least one tooth (36, 38, 40) projecting through a slot (30, 32, 34) extending in the axial direction in the sleeve (42). This tooth (36, 38, 40) can be brought by axial displacement of the setting shaft (42) into engagement with radial recesses (46) in the setting wheels (16) disposed in the hub region of the setting shaft (42). The slot (30, 32, 34) formed in the sleeve (28) is open in the axial direction at one end of the sleeve (42) and closed at the other end and at the end of the sleeve (28) at which the slot (30, 32, 34 ) is open a spreading or expansion means (60) is disposed which keeps the sleeve internal diameter constant.
