<p>PURPOSE: To reduce producing man-hour and a producing cost by means of the reduction of the number of parts by comparing an inputted signal with reference data stored in a memory part, adding/subtracting the resultant error to/from reference data of a coin stored in the memory part at the time of the presence of an error for compensation and storing it in the memory part. CONSTITUTION: A microcomputer 6 detects a time necessary for detecting maximum value data concerning a diameter from a time for detecting maximum value data concerning the quality of material. When the detected necessary time is within a fixed time, time necessitated for detecting corrected coin reference data stored in the memory part of the microcomputer 6 and maximum value data are compared to discriminate whether an thrown-in coin is genuin or counterfeit. Then the microcomputer 6 outputs a control signal to output ports C0 to C2 to control a gate part to house or return the coin, thereby reducing parts to reduce the number of producing man-hours.</p> |
