Conventionally, electronic coin verification devices have been used to determine the authenticity of coins inserted into, for example, vending machines. The electronic coin validation device utilizes the phenomenon that when metal passes through the oscillating coil, the impedance of the oscillating coil decreases and the oscillating voltage decreases.

FIG. 1 exemplarily shows a conventional electronic coin validation device, in which an oscillation voltage 6 of an oscillation circuit 2 including all oscillation coils 1 is rectified by a rectifier circuit 4, and an output voltage 5 of the rectifier circuit 4. is amplified by the amplifier circuit 6, and this amplified voltage 7 is input to the comparator circuit 8, where it is compared with two high and low reference voltages vref1 and Vref2, which are separately input to the comparator circuit 8. Second
As shown in the figure, when the coin 9 to be tested passes through the coil 1, the voltage decreases as described above, and then

If we look at Tine-11 in more detail, the output voltage 7 of the amplifier circuit 6 is ■. It is set when the coin drops from Vref2 to Vref2, but if the coin is a fake and the output voltage 7 drops further than Vref2, Vrefl is set.
It is set once when it reaches fl, and is reset when it reaches Vref2. In this case, the timer 11 is reset and runs after the start of operation until the time-up is reached, so the drive circuit 11
The reason why the upper and lower limits are set for the reference voltage using the two high and low values Vref+ and ■ref2 is to provide a range of truth/false judgment; If it is too thick, there is an increased possibility that a fake coin will be judged to be true and mixed in, and in the opposite case, a real coin may be judged to be fake and not be stored. Therefore, caution is required when setting the 10F limit of this standard 1 pillow pressure. Even if you do this, it is still possible to judge a real coin to be a fake, or conversely, to judge a coin with similar characteristics to a real coin to be a real coin.
