Furthermore, if the coin recognition apparatus detects a coin center, which is a substantially central line on a surface of the coin, has reached a magnetic sensor based on the output signal from the receiving coil when a single frequency signal is applied to the oscillator coil, the synthesized signal is applied to the oscillator coil.

  • Publication number: 20090242354
    Abstract: A coin discriminating device has a detecting part, a first switching part, a storage part, and a control part. The detecting part has a first sensor including a pair of coils, and an oscillating circuit, and is supplied with voltage from a power source, and in addition, outputs a detection signal varied by a coin passing between the coils. The first switching part switches magnetic connection of the coils between an in-phase connection and a reversed-phase connection a plurality of times while the coin passes between the coils. The control part compares the detection signal from the detecting part and a reference signal stored in the storage part so as to determine authentication and a denomination of the coin.

  • Patent number: 7584833
    Abstract: A coin discriminator measures both the surface and average electrical conductivity of coins in order to distinguish genuine minted coins from fake or bogus coins such as cast coins which may be nominally of the same material as a minted coin. The conductivities are measured using a coil to induce eddy currents within the coin. The high frequency components of the eddy current are monitored to measure the surface conductivity. The low frequency components are measured to monitor the bulk or average conductivity.

  • Patent number: 7567088
    Abstract: A foreign object detection apparatus has at least one pair of first and second members which are members configuring a space, in which bills to be processed are deposited, and disposed to face each other to push and sandwich the bills therebetween, the first member provided with antennas made of a copper foil and applied with a voltage from a voltage applying unit and the second member made of a conductive material and grounded to configure a virtual capacitor; a measuring unit which is disposed to measure a voltage generated according to electrostatic capacitance of the virtual capacitor; and a judging unit which judges the presence or not of a foreign object according to a difference between a prescribed reference signal and a changed output voltage from the measuring unit depending on a change in electrostatic capacitance of the virtual capacitor due to the foreign object included in the bills.

  • Publication number: 20090166151
    Abstract: A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or more frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties. All frequency components of the magnetic field are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters.

  • Patent number: 7552810
    Abstract: A coin discrimination sensor having an excitation coil and two detector coils arranged to detect eddy currents in a passing coin. The excitation coil is provided a composite waveform formed by adding a low frequency signal (30 KHz) with a high frequency signal (480 KHz). The two detector coils are arranged at different distances from the passing coin, and are calibrated to eliminate the common-mode voltage when no coin is present. As a coin passes by the sensor, eddy currents are induced in the coin which result in phase and amplitude shifts in the low and high frequency components of the detector signal. The low and high frequency components are separated from the detector signal, and their respective phases and amplitudes are ascertained and compared against values stored in a lookup table. These values represent the composition, thickness, and diameter characteristics of known coins, and if the signature of the processed coin does not appear in the lookup table, it can be flagged as an invalid coin.

  • Publication number: 20090101469
    Abstract: A coin sensor performs time-domain eddy-current testing using an inductance in one arm of a Maxwell bridge which is driven by a bipolar square wave having randomly-selected intervals between transitions, the output of the bridge being sampled at a high frequency. A processor stores a model which receives the drive signal and adjusts coefficients of the model so that the output matches the sampled measurements. Acceptance criteria are applied to the adjusted coefficients for coin classification purposes.

  • Publication number: 20080000751
    Abstract: A coin identifying sensor and a coin identifying apparatus has coin detecting sections (25X and 25Z) that are formed by relatively disposing a group of coin identifying sensors (21A, 21B, 21C and 21D) with each group provided with three aligned and integrated coin sensors. Each, of the sensors has a core wound with a coil. The sensors are disposed in a coin path in a direction crossing a movement direction of a coin. The first and second coin detecting sections are sequentially disposed on a coin path (4) to determine whether a coin is real or not using detection data of diameter, material and thickness of the coin based upon detection outputs sequentially obtained from the coin detecting sections.

  • Publication number: 20070205078
    Abstract: A self-checkout terminal is provided which includes a coin recycling machine which stores a coin inserted into a coin inlet in accordance with a denomination of the coin and releases the sorted coin through a coin outlet. A coin receiver receives a coin released through the coin outlet. A coin path couples a coin slot and the coin inlet, and a fake coin path diverges from the coin path toward the coin receiver. A judging unit judges whether a coin inserted into the coin slot is real or fake, and a sorting unit sorts a coin judged to be fake into the fake coin path. When a coin inserted into the coin slot is judged to be fake and is sorted into the fake coin path, information that there is something wrong with the coin is provided to a customer. A coin as change is released through the coin outlet.
