Abstract

PURPOSE:To always accurately discriminate the validity/invalidity of each coin and the sort of the coin by leading a reference coin to a detection part in the waiting state of coin feeding and setting up the detection value of the reference coin as a reference value to be compared with the detection value of an inserted coin. CONSTITUTION:This coin discriminating device 18 provided with a detection means 10 for detecting the state of an inserted coin and constituted so as to compare the detection result of the means 10 with the reference value to discriminate the validity/invalidity and sort of the inserted coin and lead the valid coin to a storing part is also provided with a carrying means 19 for carrying a coin to be a reference to the detection part 10 at a prescribed timing and a reference value updating means for updating the reference value by the detection result of a reference coin carried by the reference coin carrying means 19. The means is used as a valid coin carrying means for carrying a valid coin stored in the storing part to the detection part 10. Thereby a value influenced by a change in an external environment is used as a new reference value for discriminating processing and discriminating processing considering a change in the external environment can be executed.

2. Description of the Related Art In an apparatus for handling coins such as a vending machine, processing such as sale of goods must be performed according to the amount of coins inserted by a customer. Therefore, it is necessary to discriminate the authenticity and the denomination of the inserted coins one by one. Therefore, in the conventional coin handling device, a coin discriminating device is provided in the transport path of the inserted coins to detect the state of the inserted coins,
Based on this detection result, the authenticity of coins and the denomination are discriminated. For this reason, for example, a coin discriminating apparatus is provided with a detection coil so as to detect the impedance change of the coil when a coin approaches.

However, the state of the coin such as the impedance change of the coil due to the approach of the coin, which is detected in the discrimination process, is affected by the change of the external environment such as the ambient temperature, and the coins of the same denomination are detected. Even with coins, there is a problem that the detected value may have an error due to the difference in the external environment, and there is a problem that it is impossible to accurately discriminate the authenticity and the denomination. Also, increasing the allowable range of error in the detected value can improve the acceptance rate of coins,
In this case, the rejection performance of counterfeit coins and foreign coins will be significantly reduced.
