<p>Disclosed is an apparatus for sorting and storing coins, which can sort coins having similar materials, diameters and thicknesses, which can be adapted to varying environments, and which enables the user to modify set information freely and remotely so that various coins can be sorted easily. The apparatus includes a material detection sensor adapted to oscillate at a first frequency on the movement passage and detect the amount of change in the first frequency depending on the material of the coins; a diameter detection sensor adapted to oscillate at a second frequency on the movement passage and detect the amount of change in the second frequency depending on the diameter of the coins; a timer for setting a detection period and a detection time with regard to the amount of change in the first and second frequencies and measuring the time between a point of initial change of the first frequency and a point of final change of the second frequency to detect passing time data varying depending on the weight of the coins; and a controller for comparing the amount of change in the first and second frequencies and the passing time data with pre- stored set information to determine whether the coins are normal or not and decide the value and number of the inserted coins so that, when the coins are normal, a service is provided or not according to the value and number of the coins.</p> |
