Abstract: The respective proportions of currency items of different denominations in a multi-denominational store are adjusted in accordance with future change requirements for the different denominations. This is achieved by inhibiting the sending of a particular denomination to the store if the number of currency items of that denomination currently contained in the store exceeds a threshold, leaving more room for currency items of other denominations. There is also disclosed a multi-denominational banknote store which stores banknotes individually in radial regions of a drum, and which can rotate to bring each region into registry with an input/output conveyor.

Abstract: For automatic recognition of the authenticity of items in sheet form such as bank notes, for example in an automatic service machine, the transparency of each bank note is examined in predetermined spectral ranges. The measuring system is arranged between units of a transport system and, in a passage opening formed from a collector and a diffuser, produces a narrow read-out light beam which extends transversely over a scanning plane. The bank note is conveyed through the read-out light beam, and the light which shines through the bank note in the read-out area is collected in the collector and passed to a photosensitive detector. An evaluation device forms a single measurement value in respect of transparency in the spectral range for each of the successively scanned read-out areas, and compares the measurement values of the bank note being tested with pattern signals stored in a memory of the evaluation device.

Abstract: A recognition device for authenticating documents is disclosed. The recognition device comprises a reading head for optically scanning the documents. The reading head includes at least two modules of substantially identical construction, each of which is provided with a line of photosensors. The reading head also includes means for determining the spectral sensitivity of the modules. The recognition device also includes a conveying system for providing relative movement between the reading head and the documents being scanned. An evaluation means correlates signals provided by the photosensors with prestored values to control a sorter which sorts the documents based on their authenticity or falsehood.
