Title:
COIN DISCRIMINATING DEVICE AND COIN DISCRIMINATING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/052798
Kind Code:
A1
Abstract:
In a coin discriminating device, an oscillation control section applies a combined signal obtained by combining a plurality of signals of a specified frequency to an oscillating-side coil. An AD (analog-digital) conversion section converts the output signal from the receiving-side coil when the combined signal is applied to the oscillating-side coil into a digital signal. A frequency expanding section then expands the converted digital signal on the frequency axis. A coin discriminating section discriminates coins on the basis of the amplitude of each of the signals of the specified frequency extracted from the expanded signal. Further, in the coin discriminating device, the fact that the coin center indicating the approximate center line of the coin surface of a coin has reached a magnetic sensor is detected on the basis of the output signal from the receiving-side coil when a signal of a single frequency is applied to the oscillating-side coil. If the coin center is detected, the combined signal is applied to the oscillating-side coil.
