Zusammenfassung:	A device is proposed for preventing voltage collapses, which is used especially in the case of battery-operated apparatuses. Photographic or film apparatuses are battery-operated and frequently have two motors. If both motors now run simultaneously, then the load on the batteries is very high, so that voltage collapses occur which prevent satisfactory operation of the electronics in the cameras. An AND logic operation results in, for example in the case of a single-image circuit in a film camera, the motor for film transportation not starting at the same time as the motor for the capstan.
