償手段を有するコイン判別装置。 The type of coin is determined based on a coin passage, a coil sensor installed near the coin passage, a coin detection circuit that connects the coil sensor to a negative feedback path, and the output of the coin detection circuit and a comparison voltage. In a coin discrimination device, a comparison voltage is obtained from a linear temperature compensation circuit using a thermistor and a resistor, and a subsequent absolute value compensation circuit that takes the absolute value of a voltage below a predetermined voltage. A coin discriminating device having a temperature compensating means, characterized in that the coin discriminating device includes a temperature compensating means.
