摘要： A coin acceptor or rejector apparatus for use in coin-operated machines, characterized by a flapper controlling the direction of movement of coins to one or the other of a coin acceptance portion and a coin rejection portion, an oscillator circuit adapted to oscillate at a substantially constant amplitude, a sensing coil surrounding the coin chute, comparative circuitry for discriminating the change in current and resulting voltage within predetermined limits, and a solenoid energized by the change in resulting voltage within the limit prescribed for a genuine coin which moves the flapper to coin acceptance position.

摘要： A coin, spurious coin and the like (11) is passed in close proximity with the inductance (L1) of the resonant tank circuit of an oscillator and varies the losses of the tank circuit and thereby the amplitude of a signal produced by the oscillator in accordance with the metal content of the coin, and the like. The signal produced by the oscillator is converted to a control signal having an amplitude which when in a predetermined range indicates an acceptable coin and which when outside the range indicates a rejectable spurious coin, and the like. After passing the inductance, the coin is selectively directed to an accepted location (19) or a rejected location (18) in accordance with the amplitude of the control signal.

摘要： A programmable coin acceptor which is readily reprogrammed to accept different coin sets is described. The acceptor includes a detector (10) which generates an alternating magnetic field through two spatially symmetric flux paths (23,25). Disposed in each of the flux paths (23,25) is a detector coil (22,26). When the acceptor is in use a coin is passed through one If the flux paths (23). The resulting difference in the flux through the two paths (23,25) induces a voltage across the detector coils (22,26). The amplitude of this voltage and its phase relative to the excitation voltage are derived and compared with stored information to determine whether the coin should be accepted. The stored information may readily be changed for a new coin set by switching the acceptor to programming mode and passing selected coins from the coin set through the detector (10) in a predetermined manner.

摘要： A coil 1 is wound on a former 2 having a central opening 4 of a shape corresponding to the outline of a coin 3 to be checked and mounted with the plane of the opening at an angle to the horizontal. The opening 4 has, towards its lower side, a cross member 6 located below the transverse centre line of the coil 1 so that a coin 3b can momentarily rest on the cross member with its plane in the plane of the coil and can then turn about the cross member under its own weight and pass edge-wise through the opening in the former. A coin guide 10 guides coins edge-wise in a generally vertical direction towards the lower side of the coil so that a coin emerging from the guide enters the part of the opening 7 in the former 2 on the side of the cross member 6 away from the diameter and then turns about the cross member into the plane of the coil, at which point an output signal dependent on the characteristics of the coin as a whole is obtained. A lever 12 is included for clearing jammed coins.

摘要： @ A control device particularly for detecting the insertion of an incorrect coin or a counterfeit coin into a coin-actuated or coin-freed machine. The coin engages between a heated electrode (4) and an unheated conductor (5) and so the coin together with the electrode (4) and the conductor (5) forms "hot" and "cold" junctions. This generates an e.m.f. by a thermo-couple or the Seebeck effect. When the coin is made of the correct metal or quantity of metal the e.m.f. generated is sufficient to actuate a relay (9) to release the coin to actuate the machine or free it for actuation. Where the e.m.f. is insufficient the machine will remain inoperable. In that case the coin will be released after a predetermined time without operation of the machine.

摘要： A coin 12 to be checked is passed through a test coil 1 connected in parallel with a capacitor 2. A comparison coil 3 having an adjustable core 5 is also connected in parallel with a capacitor 4 and a direct current is passed through both coils in parallel from a rail 13 to an interrupter 14. The simultaneous interruption of the current through both coils produces between each coil and its capacitor a respective oscillatory discharge in the form of a decaying wave train and the characteristics and dimensions of the two coils and their capacitors are such that when a coil of the selected denomination passes through the test coil, the two wave trains are substantially identical. The two wave trains are compared by a comparator device 6 and a voltage comparator 7 generates a signal when the result of the comparison is below a predetermined datum, thus indicating that the coin is a genuine one.

摘要： A coin rejector device includes two or more proximity switches having detector coils (1,2) in the form of generator or oscillator coils, respectively. Each of the detector coils (1,2) has an output when the impedance on the approach of the coin to the detector coil (1) is lower than a threshold value. The threshold values of the proximity switches are preset higher than the impedance on the approach of the legal coin to the detector coils (1, 2), respectively to improve the coin selecting precision and also prevent the unfair use of illegal coin with a drilled hole.

摘要： A coin selection apparatus comprises detection coils (8, 9) and an oscillation circuit (12) which detects changes of impedances of the detection coils caused when a coin (7) pass through the detection coils, as a change of a voltage output. The detection coils (8, 9) include at least two detection coils (8, 9) opposingly arranged to coin paths (10, 11) and one detection coil (8) has coils (8a, 8b) connected in series and in phase and the other detection coil (9) has coils (9a, 9b) connected in series and in opposite phases. Those coils are arranged at a spacing 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 (12). Thus, material, thickness and diameter and other appearance characteristic of the coin are detected based on the voltage output of the oscillation circuit. Accordingly, the coin selection apparatus is of simple construction and has a small number of components.

摘要： A self-tuning coin testing apparatus having a coin sensor circuit which produces an output signal indicative of a parameter characteristic of the coins which are tested by the coin sensor and a programmed microprocessor which stores an initial acceptance limit, determines whether the output signal from the coin sensor is indicative of a valid coin, stores a signal based on the output signal for each valid coin, calculates a statistical function based on the stored signal, and finally computes and stores a new acceptance limit based on the stored signals for a predetermined number of previously accepted coins. The statistical function, is preferably weighted so that it is based upon values for only a predetermined number of the most recently accepted coins so that a recent average is maintained.
