Abstract: A banknote stacker comprising at least one first scissors linkage acting to extend a pusher into a cashbox, and at least one second scissors linkage acting transversely to said first to extend a lateral portion of said pusher to flatten a note in the cashbox.

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: Apparatus and method for aligning media. The device includes a passageway and at least one rotor. The rotor may have a surface shaped to drive a media in an intermittent fashion, or a plurality of rotors may contact the media in an intermittent fashion. Intermittent drive may also be achieved by modulating the contact pressure between a rotor and the media.

Abstract: Apparatus and method for detecting strings attached to bills or other forms of payment in a currency validator. In one implementation a string fraud detector uses polarized light to detect a string. In another implementation, polarized light and light in a different range of wavelengths are used to detect a string.

Abstract: A banknote store (10, 12, 14, 16) comprises first and second drums (18, 20; 18, 22) mounted for rotation about respective axes on, respectively, first and second shafts (51), an elongate support strip (24; 26) which can be unwound from one of the drums onto the other of the drum, and vice versa, such that banknotes (60) can be supported in succession by the support strip while that is wound around at least one of the drums, coupling means (44, 46, 50) for coupling the shafts together, first biasing means (54) between the coupling means and the first drum and second biasing means (56; 58) between the coupling means and the second drum for allowing biased relative motion between each said drum and said coupling means, and for maintaining tension in the support strip.
