Abstract

In Schreib- und Druckwerken werden heutzutage auch vielfach Gleichstrommotore eingesetzt, wobei deren Antriebswellen mit Taktscheiben versehen sind, die über eine Abtastvorrichtung für jeden ausgeführten Schritt einen Impuls für eine Steuervorrich­ tung mit einem Zähler liefert. Hierbei kann es vorkommen, daß der Gleichstrommotor mit der Taktscheibe nach einem Schrittvorgang derart hin- und herschwingt, daß der Zähler mit mehreren Zähl­ impulsen beaufschlagt wird. Diese Fehlzählungen werden erfin­ dungsgemäß dadurch vermieden, daß ein Steuerglied vorgesehen ist, das das dem Zähler (11 ) zugeführte Signal länger auf aktivem Pegel hält als das dieses auslösende und durch die Taktscheibe (3) erzeugte Taktsignal . Hierdurch wird der mechanische Bereich für Schwingungen vergrößert, ohne daß es zu Zählfehlern kommt. Nowadays there are also many types of writing and printing DC motors used, their drive shafts with Clock disks are provided, which have a scanning device for each step executed a pulse for a control device device with a counter. It can happen that the DC motor with the clock disc after a stepping process swinging back and forth so that the counter with several counts impulses is applied. These miscounts are invented appropriately avoided in that a control element is provided, the signal supplied to the counter (11) is longer active Level holds as the one that triggers and through the clock disc (3) generated clock signal. This will make the mechanical area for vibrations without causing counting errors.
