<p>PURPOSE:To accurately correct the measured value for coin passage based on errors of the standard state and the actual operation time detected at the time of coin non-passage by individually correcting the error due to the variance of temperature and the error relatively varied by the measured value because of other factors. CONSTITUTION:A ROM 12, a RAM 13, a driving circuit 14, an A/D converter 19, and a temperature detecting circuit 20 are connected to a CPU 10, which controls the coin detecting operation, through a bus 11, and a thermistor 21 is connected to the circuit 20. Errors of the measured value for coin non-passage at the time of the standard state and the actual operation are calculated and are divided into the error due to the temperature detected by a temperature detecting circuit 20 and the error due to other factors. The former error is corrected based on the function related to the temperature characteristic of a device, and the latter is proportionally corrected because being largely dependent upon the measured value.</p> |
