  • Patent number: 7984906
    Abstract: Using detectors, skewed conveyance of sheet media such as checks can be detected accurately regardless of whether part of the conveyed medium is folded over. The biased feed detection unit 33 of a check processing device 1 according to at least one embodiment of the invention determines the lengths L1 and L2 of the conveyed check 6 (ST31 and ST32) and the thickness of a folded part of the check 6 (ST33) at different positions perpendicular to the transportation direction based on the output of a paper thickness detector 25 and a length detector 26 disposed to the check transportation path 7. The folded length L3 is then subtracted from the difference ?L of the detected lengths to acquire a corrected difference ?L1 (ST35). If the corrected difference ?L1 is less than or equal to a threshold value D, the medium is determined to be conveyed normally (ST37). If the corrected difference ?L1 exceeds the threshold value D, the medium is determined to be skewed (ST38).

  • Patent number: 7708129
    Abstract: A multiple coin actuation mechanism has a latch biased to an inward home position with its inner end extending through an upstream side of a first coin slot of a stationary front cover plate toward a rotatable carrier wheel and generally alongside an unobstructed path for insertion of a first coin through the first coin slot into a first coin recess of the carrier wheel. The latch is pivotally yieldably movable away from the carrier wheel due to engagement with a second coin in a second coin recess in the rotatable carrier wheel, as the second coin is brought into alignment with the first coin slot, to allow the second coin to pass under the latch while the latch remains in contact with the second coin, preventing its removal from the second coin recess outwardly through the first coin slot, as the carrier wheel rotates past the first coin slot.

    Abstract: A coin discriminating device has a sensor electrode and an oscillator. The oscillator is coupled to the sensor electrode. The oscillator generates an output signal with a frequency which is capacitively controllable. A frequency detector detects a frequency deviation in the oscillator output signal, caused by a variation in capacitance at the sensor electrode when a coin is positioned in the vicinity of the sensor electrode. A processing device determines the thickness of the coin from the frequency deviation. The coin discriminating device is arranged such that the variation in capacitance occurs between the sensor electrode and a surface of the coin.

  • Patent number: 7131539
    Abstract: When a thickness sensor detects a corner fold in a front end part of the paper sheet being carried, a light sensor checks whether a break exists or not in the front end part. When there is no break, it means the thickness sensor does not detect a corner fold but a foreign matter such as a tape mending a break. When there is a break, it means the thickness sensor detects a corner fold in the front end part. When there is no corner fold, the light sensor checks the front end part. When there is a break, it means there is a corner break but no corner fold in the front end part. When there is no break, it is a normal state. Regarding the back end part, a corner fold is detected in similarly to the foregoing.

    Abstract: A capacitance sensor measures a coin to determine geometrical parameters thereof and to allow assessment of different geometrical parameters of a coin which influence the measured capacitance. In a preferred arrangement, a mechanical arrangement alters the capacitance between two electrodes as a function of the diameter of the coin. This assessment is used in combination with a further measured capacitance which is a function of coin diameter, coin thickness and surface relief of the coin. The initial evaluation of diameter is useful in determining the separate influences of coin thickness and surface relief. The invention is also directed to the method of coin evaluation.

  • Patent number: 6902050
    Abstract: The validity of a coin is tested in a coin mechanism typically used for vending products. A test arm which is integrally and resiliently connected to a back plate contacts a coin when the coin wheel is rotated, and the test arm resiliently deflects in response to contact with the characteristic of the coin tested. The validity of the coin is established by the degree of movement of the test arm. More than one test arm functions to test different characteristics of the coin to establish validity and the prevent illegitimate dispensing of products. When a coin is not present, the test arm is not deflected to maintain its resiliency characteristics. Preferably the coin mechanism is assembled from a relatively few injection molded durable plastic parts.

  • Patent number: 6892871
    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.

  • Patent number: 6053300
    Abstract: A coin validator is provided with at least two reference positions (U, D) for determining a diameter related characteristic of a coin being validated. In order to reduce the running to the testing station, the timing of a trailing point of the coin passing a first reference position (U) is used to determine the diameter related characteristic. Embodiments using optical inductive and piezo-electric sensors associated with the reference positions are disclosed. An inductive sensor for a coin validator comprises an elongate coil, which, when in use, is arranged such that the magnetic field is substantially constant across the width of the passageway. The use of coils of this type have the advantage of wrap around coils but enable the coin passageway to be shallower and be opened. A coin validator is described wherein the backwall of a coin passageway is movable to and fro so that the depth of the coin passageway can be adjusted.

    Abstract: A coin validator has a thickness sensor formed by two coils positioned one on each side of the coin path. The coil outputs are processed separately to derive values which, when combined, produce a thickness-indicating measurement which is independent of coin position. Each output may be processed to give values which are linearly dependent upon coin position with the same constant of proportionality. Alternatively, one output is scaled relative to the other to an extent dependent upon the thickness for which the coin is to be tested, so that the thickness-indicating measurement does not vary significantly over a region which corresponds to a likely maximum variation in the position of coins of that thickness.

  • Patent number: 5002174
    Abstract: A coin validator of a static capacitance system for discerning the thickness and/or pattern of a coin in a non-contact manner. A pair of electrode assemblies including a first and a second sensor electrodes and a first and a second guard ring electrodes are disposed on the corresponding sides of a coin path. The first and the second guard ring electrodes prevent the dispersion of electric lines of force generated by the first and the second sensor electrodes. The first and the second sensor electrodes are impressed with resonating output signals from resonators. Under such condition, when the coin passes through the coin path between these electrodes, the entire inter-electrode capacitance changes to fluctuate the resonating output voltage and hence allow the thickness and/or pattern of the coin to be detected. The guard ring electrodes serve to focus the electric lines of force into a beam to thereby allow the thickness of the coin to be detected finely.

    Abstract: Two sensors (2, 3) are placed opposite each other against the rim of the coin (5). By this, a signal, corresponding to the diameter of the coin (5) is produced and a drive (18/19, 23/24) is driven which moves two support members in order to support a coin between them (13), the diameter of which corresponds to the distance between the sensors (2, 3) in a position that is centered to a test coil (10) of an inductive coin testing device.

  • Patent number: 4749074
    Abstract: A coin sorting apparatus in which the oscillation constants of oscillators change with the passage of a coin, and the amount of change in each of the oscillation constants or a value converted therefrom is compared with a reference value of a coin to be identified which is stored in a memory to identify whether the coin is genuine and the class thereof. Whether the reference values for each coin are corrected is determined by a plurality of counters which correct the reference values of corresponding classes of coins when their counts exceed a predetermined set value. At the same time, when the inserted coin is identified as genuine, a corresponding counter is activated, thus improving the performance of eliminating spurious coins without reducing the acceptability of genuine coins even under ambient temperature changes or secular variations of component elements with time.

  • Patent number: 4741427
    Abstract: A coin acceptor which receives coins in a slanted coin chute with a final size gauge system. The coin is first rebounded against a tapered wall and enters a first zone. All three coin sizes enter the first zone and then the lightest weight one passes down a tapered ramp which is spring loaded, but the lightest weight coins will not depress the ramp and therefore such coins are diverted into a second zone. The heavier different sized coins pass down and trip the tapered ramps, both a first and second one, and then the widest of the coins continues downwardly in the first zone to be processed and sized for diameter. The largest diameter coin is trapped between two pins where it is then tilted off of a ramp onto a diverter and passes into a third zone for processing. As all of the coins reach the bottom of their three separate zones, they enter into a final size gauge system which has three coin chutes sized precisely to reject any coin which is bent, burred, or oversized.

  • Patent number: 4706795
    Abstract: A coin discriminator for discriminating good coins from bad coins among a plurality of different types of coins and sorting the coins by denomination has a cradle for selecting the coins in accordance with their diameter, and a swing lever which is urged in a direction toward the space between the two ends of the cradle. The swing lever biases a small coin so as to cause it to pass the space between the two ends of the cradle. A large coin urges the swing lever and is removed from the cradle.

  • Patent number: 4705154
    Abstract: A coin selection apparatus comprises a plurality of detection coils and an oscillation circuit which detects changes of impedances of the detection coils caused when a coin pass through the detection coils, as a change of a voltage output. The plurality of detection coils include at least two sets of detection coils each including two detection coils opposingly arranged to the coin path. One set of detection coils has its two coils connected in series and in phase and the other set of detection coil has its two coils connected in series and in phase opposition. The two sets of coils are arranged at a spacing along the coin path smaller than a minimum diameter of a coin to be selected and all of the coils are connected in series and connected as a resonance element of the oscillation circuit. Thus, material, thickness and diameter and other appearance characteristic of the coin are detected based on the voltage output of the oscillation circuit.

  • Patent number: 4577744
    Abstract: A coin discriminator comprises photoreceivers along a vertical drawn from an infed coin run chute whereby screening and illuminating the photoreceivers from a photoemissive source permit coin diameter identification. Two coils on either side of the chute detect the coin alloy. Coin thickness is determined using a stepshaped transversal section across the chute track where the step risers lie opposite the photoreceivers which transmit a signal word identifying the infed coin diameter and thickness. This signal word is compared with memorized words representative of acceptable coin dimensions. If the dimensions are acceptable, a combination of impedances in a bridge circuit incorporating the coils is selected in terms of the alloy corresponding to the acceptable dimensions. If the bridge balances for this combination as the coin rolls between the coils, the coin is accepted.
