Abstract

In a capacitive coin detector capacitor electrodes (3, 4) connected to an electric circuit for detecting capacitance variation during the passage of a coin (5), are arranged on a rearwardly inclined wall (1) of a sloping coin chute having a coin support rail (2). One or more first electrodes (4) are located on the wall (1) in such a manner that the edge of a coin (5) in the chute overlaps said electrode a little or not at all, dependent on its size. A further electrode (3) is located to be closer to the centre of the coin path and has a considerable area. In this manner the capacitive coupling between the electrodes (3 and 4) via the coin (5) is substantially determined by the coin overlap of the first electrode(s) (4). With the first electrodes (4) located at the upper edge of the coin, the coin diameter can be directly checked. When they are located at the lower edge of the coin in a coin chute, where the coin support rail forms an angle of less than 90 DEG with the wall, it is possible to check the coin thickness. <IMAGE> [GB2062327A]
