Abstract: A banknote acceptor 1 for authenticating a banknote 2, has a sensing station S with detector 18 that produces image signals corresponding to a face the banknote. A processor 24 pre-processes the image signals and compares them with stored reference data corresponding to an acceptable banknote from memory 25 to determining the authenticity of the banknote and its denomination. A display device 29 displays an image 31 corresponding to the banknote under test based on the image signals from the detector 18, to allow the user to perform a visual check that the banknote detected at the sensing station corresponds to the banknote under test presented by the user. Also, the detected denomination of the banknote is displayed on device 32. The user can accept or reject the banknote using buttons 33 and 34, and retrieve images of previously accepted banknotes with button 35.

Abstract: The coin validator is calibrated by inserting a calibration key different from coins to be validated in a static position in the validator such that eddy currents are induced in the key by operation of its sensor coils so as to produce a calibration value of signals form the sensor coils as a function of the individual characteristics of the validator. The calibrating value of the sensor signals may be compared with ensemble data concerning corresponding calibration values derived from an ensemble of coin validators of the same design.

Abstract: In coin discrimination apparatus, a coin under test rolls past first and second inductive sensors (C1, C2) which produce first and second coin signals (x.sub.1, x.sub.2) in dependence upon the coin under test. The coin signals are compared with data defining first and second stored windows (W.sub.1, W.sub.2) to determine acceptability of the coin. In accordance with the invention the data for the first and second windows (W.sub.1, W.sub.2) are stored respectively for providing both a first and a second window width (W.sub.11, W.sub.12 ; W.sub.21, W.sub.

Abstract: Coin discrimination apparatus comprises a path (1) for passage of coins under test; sensor coils (2, 3, 4) forming an inductive coupling with a coin under test during its passage along the path, each of the sensor coils being connected in a resonant circuit (10, 11, 12) which exhibits a resonant frequency that varies in dependence upon the inductive coupling between the coil and coin, control circuitry (14) which maintains the resonant circuit at the resonant frequency while a coin under test is inductively coupled to the coil, and amplitude responsive circuitry (MPU) responsive to the change in the amplitude of an oscillatory signal developed by the resonant circuit when the coin under test passes the sensor coil to discriminate between different coins, wherein the control circuitry includes a zero crossing detector (A1) responsive to the oscillatory signal crossing a zero threshold level for producing a rectangular waveform corresponding to the oscillatory signal, and drive circuitry (FF1, 2; OR1, 2) respon

Abstract: A multicoin tester has a coin inlet path 1 along which coins under test run edgewise past coils 2, 3 on opposite sides of the path, and through the windings of a coil 4. Electronic circuitry responsive to the inductive coupling of the coin with the coils operates a gate 5 to either reject the coin onto path 1b or to accept the coin into path 1a. As shown in FIG. 2 each of the coils 2, 3 and 4 is arranged in a parallel L-C resonant circuit 10, 11, 12 connected in the feedback path of an amplifier A1, the resonant circuit being energised sequentially by multiplexer M1. Each of the circuits 10, 11 and 12 has its own natural resonant frequency. The resonant circuits 10, 11, 12 are driven by a voltage controlled oscillator VCO. A phase locked loop including a phase comparator PS1 drives the oscillator VCO at a frequency corresponding to the natural resonant frequency of whichever of the circuits 10, 11 and 12 is connected thereto.
