1. An apparatus for singling value documents, comprising:
a feeding device, which is adapted to feed a respectively uppermost value document of a stack of value documents to a picking device which is adapted to pick the value document from the stack,
a conveying device, which is adapted to receive the stack and to convey it relative to the feeding device,
at least one distance sensor, which is adapted to measure at least one distance of the respectively uppermost value document of the stack relative to the feeding device and to generate at least one corresponding distance sensor signal,
at least one stack sensor which is adapted to detect a height from the respectively uppermost value document of the stack to a lowermost value document of the stack and/or a density of the stack of value documents and to generate at least one corresponding stack sensor signal, and
a control device, which is adapted to control the conveyance of the stack relative to the feeding device and/or the location of the feeding device relative to the stack, to the respectively uppermost value document of the stack, on the basis of the at least one distance sensor signal and the at least one stack sensor signal.
