A banknote acceptor illuminates a banknote as it passes through an evaluation channel in a manner to locate the banknote in the width of the channel. A photo sensor array receives reflected light from the surface of the banknote and has a series of responsive divisions across an illuminated banknote. These divisions are sampled and analysed according to the banknote position to determine the authenticity of the banknote. Both apparatus and method steps are disclosed.

Photo sensor array for banknote evaluation

A simple high optical efficiency reflective optical sensor for bill validator uses an inexpensive bulb having a case which is transparent to efficient luminous radiation. This case is used as a wave guide to return reflected radiation to at least one photo detector situated directly under the transparent bottom of the case. The bulb emits a narrow beam of light and is positioned in close proximity and perpendicular to a bill surface and illuminates it. The light reflected or fluoresced by the bill is collected widely with a convex lens end of the bulb case and this collected radiation is transmitted through the bulb case to the at least one photo detector. Preferably, the bulb is a light emitting diode.

Reflective optical sensor for bill validator

A banknote validator includes a banknote processing channel, a series of sensors located along the channel for scanning a banknote as it moves past the sensors, a central processing unit for controlling the operation of the validator and receiving and processing the signals from the sensors. A removable memory storage arrangement is insertable in a receiving location of the validator. The removable memory storage arrangement, when received in the receiving location, forms an electrical communication path with the central processing unit and provides to the central processing unit the logic for operating the validator. Preferably, the removable memory storage arrangement is a serial flash module having its own electronic address used by the validator to confirm the encoded software being downloaded to the validator has not been tampered with. As a further preferred security feature the validator is designed such that it will only operate when a removable flash module is received in the validator.

A planar induction sensor for sensing of security features of documents having changing magnetic and (or) conducting properties is of a multilayer printed circuit board design. The sensor comprises a planar current transformer with a spiral-type primary coils and one or several turns of secondary coil in an adjacent layer of the printed circuit board. The secondary coil of the current transformer is connected to an operating coil, which is situated at a sensing edge of the sensor. The operating coil can be formed by external wires or can be incorporated in the circuit board of the current transformer. When a security element, made from the magnetic or conductive material moves past the sensing edge of the sensor, a change in inductance of the induction sensor occurs. In a preferred embodiment, two induction sensors with individual associated electronic circuits were located on opposite sides of validator channel. Analysis of both signals from the sensors allows correction of the signal to reduce variation caused by changing distance of the security document from each sensor.

Induction sensor using printed circuit

An improved eddy-current sensor for a coin validator uses a thin ferrite plate having a suitable aspect ratio for two coils. One of them serves to generate magnetic field and the other serves to produce a voltage if there is a coin with eddy-currents in it. The first coil is short cylindrical one and is placed in the middle of the biggest surface of the plate. Its axis is perpendicular to the plate surface. The second coil is wound around the plate with a half coil at one end of the plate and an opposite half coil at the opposite end of the plate, plate symmetrical about center of the plate. The sensor is positioned in the pathway of the coin validator such that the moving direction of movement of the coin is along the pathway perpendicular to the axis of the first coil and makes with the largest axis of the plate an angle about 45 degrees.
