COIN SELECTION DEVICE |
摘要 |
<p>A coin selection device is of a type in which reference voltage is automatically adjusted in accordance with variation in the output level of a receiving coil in a standby mode. A oscillating coil and a receiving coil are disposed on both sides of a coin path. A peak of output level of the receiving coil and the reference voltage are compared each other in a comparator for detecting whether inserted coin is true or false. The output level of the receiving coil in the standby mode is stored so that variations in temperature and circuit parameters can be taken into account in the reference voltage level.</p> |
