Abstract
An arrangement in an electric office printing machine which makes it possible, in a simple manner, to replace and safely retain a print element of a circular disc type on the motor shaft of the machine. This result is achieved by a coupling device which can be acted upon by an operating means. The coupling device is so designed that the print element attached to the end of the motor shaft is placed on a plate, included in the coupling and axially movable, after which the print element, by way of the operating means, is moved on to and fixed on the motor shaft.
