Improvements in and relating to apparatus for checking the validity of coins |
| abstract |
Apparatus for checking the validity of coins, comprising electrically operated sensor means (HF1, 300) for interacting with a coin (7) to be checked and producing an information signal in response to said interaction, characterised in that the sensor means comprises a single sensor operable both in a coin arrival sensing mode and in coin checking mode, and in that the apparatus further comprises means for applying electrical power to said sensor at a low level so as to operate the sensor in said coin arrival sensing mode, said low level being sufficient for said information signal (502) to be produced to a detectable degree during an initial period of said interaction, and control means (316) for detecting the occurrence of said information signal as an indicator of arrival of a coin at said sensor and in response increasing the power applied to said sensor so as to operate the sensor in said coin checking mode, and thus increasing the information signal. |
