Abstract
The invention relates to a printing unit in an electric office printing machine, and more exactly the invention has for its object to provide an arrangement which makes it possible with a minimum of manual operations to change print elements of circular disc type. This is achieved by moving the printing unit away from the carriage at the same time as the print element by the action of a special coupling is detached from the motor shaft on which the print element is supported, this being possible only when the attachment device for the print element is in such a position that it can receive a new print element.
