 und schliesst sich die Stromzuführung 10,11 zum Motor 2. Der Radierapparat 1 ist also nach dem Herausziehen ohne Einschaltbewegung soiort funktionsbereit. 



   Die Form des in Fig. 1 dargestellten grösseren Teiles des Gehäuses 3 kann zylindrisch oder aber auch prismatisch sein. Eine dementsprechende Form weist auch die Lagerhülse 8 auf. 



   In Fig. 2 ist das Gehäuse 18 birnenförmig ausgebildet, dementsprechend   auch de : obere Teil 19   der Lagerhülse. Zur freien Lagerung des vorderen Teiles des Radierapparates 1 ist die Lagerhülse im unteren

    PATENTANSPRÜCHE :    
1. Elektrisch betriebene Radiervorrichtung mit einem in Rotation verstzbaren Radierkörper, einer, diesen in der Ruhestellung aufnehmenden Lagerhülse und einem, die Lagerhülse tragenden Sockel, sowie einer   selbsttätigen Schalteinrichtung   zum Abschalten des Motors. wenn sich der   Radisrkorpsr in dsr Lager-   hülse befindet, dadurch gekennzeichnet, dass der Motor (2) und der   Radierkörps ? 5)   in bzw. an einem gemeinsamen Gehäuse (3,18) gelagert sind, die Lagerhülse (8,   19)   sich innerhalb des Sockels (7) befindet und die Kontaktvorrichtung (10, 11, 12) durch einen, durch das   Gehäuse   (3, 18) zu   betätigenden,   in die Lagerhülse (8, 19) hineinreichenden Anschlag ausgelöst wird.

 and the power supply 10, 11 to the motor 2 closes. The eraser 1 is thus ready for use immediately after it has been pulled out without a switch-on movement.



   The shape of the larger part of the housing 3 shown in FIG. 1 can be cylindrical or else prismatic. The bearing sleeve 8 also has a corresponding shape.



   In Fig. 2, the housing 18 is pear-shaped, accordingly also de: the upper part 19 of the bearing sleeve. For free storage of the front part of the eraser 1, the bearing sleeve is in the lower

    PATENT CLAIMS:
1. Electrically operated erasing device with an eraser body that can be rotated, a bearing sleeve which receives it in the rest position and a base carrying the bearing sleeve, as well as an automatic switching device for switching off the motor. when the Radisrkorpsr is in the bearing sleeve, characterized in that the motor (2) and the eraser body? 5) are mounted in or on a common housing (3, 18), the bearing sleeve (8, 19) is located inside the base (7) and the contact device (10, 11, 12) by a, through the housing (3 , 18) to be actuated, into the bearing sleeve (8, 19) reaching into the stop is triggered.

Claims (1)

2. Radiervorrichtung nach Anspruch l, dadurch gekennzeichnet, dass als Anschlag eine in der Lagerhülse (8) axial bewegliche Hülse (9) dient, die durch das Gewicht des Radierapparates (1) nach unten geschoben, den Kontakt (10, 11) öffnet, wobei gleichzeitig der Motor (2) kurzgeschlossen, ist. 2. Eraser according to claim l, characterized in that a sleeve (9) which is axially movable in the bearing sleeve (8) and is pushed down by the weight of the eraser (1) opens the contact (10, 11) as a stop, at the same time the motor (2) is short-circuited. 3. Radiervorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass als Anschlag eine, durch eine Ausnehmung in der Wand der Lagerhülse (19) in diese hineinragende, federnde Nase (16) angeordnet ist. 3. Erasing device according to claim 1, characterized in that a resilient nose (16) protruding into this through a recess in the wall of the bearing sleeve (19) is arranged as a stop.
