Abstract: A method of and apparatus for determining authenticity of coins based on difference in surface irregularity pattern of coins. A coin passage is inclined at a predetermined angle, and an exciting coil is arranged near one side wall of the coin passage such that the two magnetic poles of the exciting coil face the coin passage. Two receiving coils having substantially identical characteristics are arranged near the same passage wall such that they are electromagnetically coupled with te exciting coil. The exciting coil is excited at a predetermined frequency, and an influence of a demagnetizing or reactive magnetic field caused by eddy current induced on the surface of a coin is detected by the receiving coils. The level of the demagnet or reactive magnetic field varies depending on difference in surface irregularity pattern of coins, and thus authenticity of coins can be determined based on the difference in surface irregularity pattern. This can be attained with a simple, inexpensive arrangement.

Abstract: A data recording method and device for an optical memory card which is adapted to prevent a recording error due to step-out during a data recording operation, and minimize a decrease in the recording capacity of an optical memory card. While data are recorded, an output from an SYNC mark detection circuit (2) and an output from an internal synchronization signal generation circuit (3) are compared with each other in a comparator circuit (4). When step-out occurs, a write signal generation circuit (5) is stopped and the data recording operation is interrupted, and a re-recording operation is started at a frame adjacent to the frame in which a recording error occurred, on the basis of the value in a write cycle counter, whereby a decrease in the recording capacity of the optical memory card is minimized.

Abstract: A coin inspection method and a device which can inspect a coin with a high precision, by extracting a large amount of information from a sensor detection signal waveform. In coin inspection which is performed based on a detection signal waveform of a magnetic sensor disposed along a coin pathway through which the coin passes, a differential waveform of the detection signal waveform is determined, first information indicating a peak position of the differential waveform, second information indicating a value of the detection signal waveform at the peak position of the differential waveform, and third information indicating a value of the differential waveform at the peak position of the differential waveform are extracted, and the extracted first through third information are used to inspect the coin.

Abstract: A coin discharge device has a removable coin tube cassette and an empty sensor 5 for accurately detecting the presence of coins within the coin tubes. A sensor mounting 30 is designed to withdraw the sensor 5 from the cassette accommodation part 22 when the coin tube cassette is removed from the device. However, when the coin tube device is inserted into the cassette accommodation part 22, the sensor mounting 30 moves the sensor 5 into the accommodation part 22 so that it abuts one side of the coin tube cassette to sense coins therein.
