Abstract: A money changer for automatic coin machines, comprising a casing in which a plurality of serially arranged tubes are mounted to store coins in a column shape, light barriers associated to the tubes at least in the upper and lower regions with each light barrier having a light-emitting element and a light sensitive receiving element which are superposed on the same side of the coin tube whereas the opposite side of the coin tube has arranged thereon a prism which reflects the received light back to the receiving element, and a control circuit for the money changer into which the output signals of the light receiving elements are entered, wherein the casing has a wall portion in parallel with the series of the coin tubes, a printed circuit board for the control circuit is mounted on the opposite side on the wall portion and carries the light-emitting elements and light-receiving elements which are directed towards the respective coin tube via holes in the printed circuit board and in the wall portion.

Abstract: A method for measuring the diameter of coins in coin validators, comprising the steps below: The coins traverse an electromagnetic field which is formed such as to partially hide the field, at least also by their upper area. The field is generated between at least one transmitter coil and a receiver coil. The transmitter coil is periodically acted on by a short transmission pulse the duration of which is small as compared to the time of coin passage. The maximal attenuation values are determined for different times of the transmission pulse. The attenuation values measured are extrapolated into time 0. The measured value determined by extrapolation is compared to a predetermined acceptance band or a predetermined characteristic line for coin diameters for comparison to a stored setting.

Abstract: To identify an embossed image of a coin in an automatic coin machine, the coin requiring identification is moved past an image receiver and a light source, the light source having at least two lighting portions which illuminate an object field of the coin requiring identification from different directions under the same angle with respect to the surface normal of the object field and with wavelength ranges which do not overlap each other. An image receiver records one picked-up exposure of the object field from which images are obtained for each of the individual lighting portions of the individual wavelength ranges. A maximum image is then determined from the images, wherein each pixel has associated therewith the maximal intensity value from the images of the individual wavelength ranges. A genuine-coin or counterfeit-coin signal is determined from the maximum image.

Abstract: A process for identifying an embossed image of a coin in an automatic coin tester, in which a coin is moved to an image receiver and a light source, the image receiver picks up at least one image of the embossed image of the coin, and a validation device compares the image to a first reference pattern to find out whether the first reference pattern is contained in the image which was picked-up. If the first reference pattern is contained in the image, the validation device determines whether a second reference pattern is contained in an area the position of which is determined relative to the position of the first reference pattern, the validation device producing a genuine coin or counterfeit coin signal for the coin depending on the coincidence of the image with the reference patterns.
