ABSTRACT Printing Mechanism A printing mechanism comprises a housing (12, 14) in which a plurality of coaxially disposed setting wheels (16) are arranged with which type carriers (20) carrying printing types (22) are in a drive connection and can be brought into predetermined setting positions. A setting shaft (42) extends through centre openings disposed in the hub region of the setting wheels (16), said setting shaft (42) being mounted rotatably and axially displaceably in a wall (15) of the housing. Said shaft carries at one end at least one driver (36, 38) which by axial displacement of the setting shaft (42) is adapted to be brought into engagement with radial recesses (47) formed in the hub region of the sett- ing wheels (16). At its other end the setting shaft (42) carries an actuating knob (48). At least two detent means are provided for arresting the setting wheels (16) on ro- tation thereof and holding the setting wheels (16) in their rest position. The one detent means (70-76, 90) is so formed that it is in operative connection with the particular sett- ing wheel (16a) selected and in addition at the most with the setting wheels (16) arranged between the selected setting wheel (16a) and the other end of the setting shaft (42).
