Method for providing measurement data from a device for processing value documents and value document processing device

An apparatus for processing value documents, comprising:

• a feeding device for feeding individual value documents, an receiving device for receiving processed value documents, a transport device for transporting individual value documents from the feeding device along a transport path to the receiving device;
• a sensor device with an intermediate memory, having one or several sensors for capturing respectively at least one physical property of individual value documents fed and transported along the transport path, and being configured to store in real time in the intermediate memory measuring data for the value documents produced by means of the one sensor or the several sensors, wherein the sensor device can be set to a measuring mode of operation, wherein the measuring data for individual value documents are captured and stored in the intermediate memory, such that measuring data for a plurality of value documents is stored in the intermediate memory simultaneously, and a criterion is monitored that the current utilization of the intermediate memory exceeds a predetermined limit utilization, and a rest mode of operation, wherein no measuring data are stored;
• a permanent memory for permanently storing measuring data and/or an interface for an external permanent memory for permanently storing measuring data;
• wherein the apparatus is configured, when the sensor device is in the measuring mode of operation, to so drive the feeding device when the criterion is fulfilled that the feeding device does not feed any further individual value documents, to set the sensor device to the rest mode of operation and to permanently store the measuring data from the intermediate memory in the permanent memory or external permanent memory, and, during the storing or after the storing, to release the intermediate memory again, and, after the release of the intermediate memory, to so drive the feeding device that the feeding device restarts the feeding of individual value documents, and to set the sensor device to the measuring mode of operation.
