Abstract:
1. A device for handling currency notes comprising: an input and output unit for inserting and disbursing/issuing currency notes, a sensor unit to determine the denomination of the currency notes inserted, a transport unit to transport currency notes, a collective receiving bin to accept currency notes, where said collective receiving bin is configured such that currency notes of all denominations of a preset currency set can be accepted and that only currency notes can be taken to the collective receiving bin with the aid of the transport unit, a first recycling receiving bin and at least one second recycling receiving bin to which currency notes can be taken with the help of the transport unit and from which currency notes accepted can be removed again and be taken with the help of the transport unit to the input and output unit, wherein a control unit is provided in which for each recycling receiving bin data are stored concerning which denominations are acceptable, where in the first recycling receiving bin currency notes of a first and a second denomination and in the second recycling receiving bin currency notes of a third denomination are accepted, wherein the control unit, after a currency note has been inserted through the input and output unit, depending on the denomination ascertained with the help of the sensor unit and depending on a predetermined deposit algorithm, assigns the input and output unit, the collective receiving bin or one of the recycling receiving bins to the currency note inserted as target storage to receive the currency note inserted, wherein the transport unit transports the currency note to the target storage, and wherein the control unit, in order to dispense a preset amount, depending on the denomination and depending on a preset withdrawal algorithm, ascertains which currency notes are taken from which recycling receiving bins and issued by way of the input and output unit; and wherein the control unit, depending on the stocks of the recycling receiving bins identifies at least two potential bundles of currency notes with the aid of which the specific amount can be paid out at least approximately, preferably exactly, and wherein the control unit depending on at least one preset criterion identifies an optimal bundle of currency notes from the potential bundles of currency notes, and activates the transport unit such that said transport unit transports the currency notes from the optimal bundle of currency notes to the input and output unit; and the control unit identifies and establishes in a first step a first valid bundle of currency notes as a temporarily best bundle of currency notes, the control unit checks in a second step whether an additional valid bundle of currency notes exists, the control unit, in a third step, compares said additional bundle of currency notes with the temporarily best bundle of currency notes and, depending on the preset criterion or preset criteria, determines which of the two bundles of currency notes is better with respect to the criterion or criteria, and the control unit establishes in a fourth step the additional valid bundle of currency notes as the temporarily best bundle of currency notes if the comparison in the third step showed that the additional valid bundle of currency notes is better than the hitherto temporarily best bundle of currency notes and otherwise retains the temporarily best bundle of currency notes unchanged and repeats steps two to four until no further valid bundle of currency notes exists, and then establishes the temporarily best bundle of currency notes as the optimal bundle of currency notes.
