 und das Typemad 3 zu entlasten, ist in der Typenradbuchse 2 eine weitere   Nut' vorgeselen, welche mit   einem an der Platine 10 befestigten Winkelarm 16 zusammenarbeitet. Das vordere Ende des Winkelarmes 16 ist etwas stärker und in gleicher Weise. abgebogen wie das Ende 12' des   Gleitstückes- ?,   so dass es während des Druekens die Typenradbuchse 2 umfassen oder dafür an Stelle des Endes   12'des   Gleitstüekes 12 als Anschlag dient.

 Druckhammer vorbeibewegt wird.

   Spricht jetzt der   Druekhammer j ! 7   an, soll also von Buchstaben auf Zahlen gewechselt werden, so wird der Schieber 12 mit seiner Nase über Schlitztiefe a gehoben und die Buchse 2 mit dem   Typenrad.' ! freigegeben ;   sie verschiebt sich unter dem Einfluss der Feder 9 auf die 
 EMI2.2 
 zeitig wird die Feder 11 unter Druckspannung gesetzt. Nach dem   Rückgang   des Druckhammers 17 fällt der Schieber 12 mit seiner Nase an der Innenseite des Flansches der Typenradbuchse 2 herab (s. Fig. 3).

 gekennzeichnet, dass für die beiden   Einstellungen #Zahl" und #Buchstabe" zwei Kraftquellen   vorgesehen sind, welche durch den Druckhammer ausgelöst werden.

 and to relieve the typemad 3, another groove 'is provided in the character wheel socket 2, which cooperates with an angle arm 16 attached to the board 10. The front end of the angle arm 16 is somewhat stronger and in the same way. bent like the end 12 'of the sliding piece? so that it encompasses the character wheel bushing 2 during printing or serves as a stop instead of the end 12' of the sliding piece 12.
 EMI2.1
 Print hammer is moved past.

   Now speaks the push hammer j! 7, so if you want to change from letters to numbers, the slide 12 is lifted with its nose over the slot depth a and the socket 2 with the type wheel. ' ! Approved ; it shifts under the influence of the spring 9 on the

 early the spring 11 is placed under compressive stress. After the pressure hammer 17 has retreated, the slide 12 drops with its nose on the inside of the flange of the character wheel bushing 2 (see FIG. 3).

 down (see Fig. 2).



   PATENT CLAIMS:
 EMI2.4
 marked that two power sources are provided for the two settings #Number "and #Letter", which are triggered by the print hammer.

Claims

2. Adjustment device according to claim 1, characterized in that two different strong springs serve as power sources, of which the force of the stronger one also serves to tension the weaker one.

3. Adjustment device according to claim 2, characterized in that the tension of the stronger springs is brought about by the motor driving the type wheel shaft, in particular the type wheel shaft itself.

4. Adjustment device according to claim 1 and 2, characterized in that a lever (6) provided on the character wheel socket (2) is used to transmit the motor force and tension of the springs, which lever engages in a two-stage clutch disc (glasses 7).

5. Adjustment device according to claim 1 to 3, characterized in that two grooves (a, b) are provided for fixing the two positions "letter" and "number" in the type wheel socket, in which a latching (slide 12 ) can occur.

6. Adjusting device according to claim l and 4, characterized by a resilient lever (15) which, during an operation, receives the coupling member (7) in its working position and thus the spring (9) in the tensioned state.

7. Adjustment device according to claim 5, characterized in that a special stop (16) is provided by which, in cooperation with a further groove (c) provided on the type wheel, a relief of the star device (slide 12) during the work processes with the exception of the change is effected.
