摘要： A coin testing apparatus comprises transmitting and receiving coils on opposite sides of a coin passageway. The transmitting coil is connected to high and low frequency oscillators. In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier rectified by a rectifier and smoothed by a long time-constant circuit. The initial rise in level caused by a coin entering between the coils is detected by an instantaneous level change comparator which responds to the rate of change of signal level at the output of the long time-constant circuit becoming equal to a preset threshold and causes a normally closed switch to be opened. When the switch is closed a comparator compares the signal with a reference value from a source and adjusts the gain of the amplifier until the signal corresponds to the reference value. Upon the arrival of the coin the switch is opened and a long time-constant circuit causes the gain of the amplifier to be maintained at the level before the arrival of the coin. A window comparator compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier.

摘要： A coin validating arrangement for a coin operated machine, comprising a coin chute (5) having an upstream coil (8) for sensing a true coin and producing a Q signal output only when a true coin is properly inserted, an obturator (11) generally downstream of the true coin sensing coil, a coin acceptance coil (21) generally downstream of the obturator, and a validating circuit (41) which enables the coin acceptance coil to produce an A signal output which in turn generates an accept signal which activates the machine only when no Q signal output is being produced. In a preferred arrangement, an intermediate or zoning coil (18) produces a Z signal output as it watches the coin through the obturator from the Q coil to the A coil, and production of the accept signal is also dependent on the Z signal.

摘要： An improved coin chute assembly wherein the housing contains a coin receiving opening, a first coin exit opening, a second coin exit opening, and a coin passageway disposed therein and interconnecting the coin receiving opening with the first and second coin exit openings. The coin passageway is characterized as having an upper coin path, a coin receiving section and a coin reject section, the upper coin path being oriented to permit a coin to fall in a substantially downward direction through the chute assembly and thus through the coin receiving section towards the first coin exit opening or through the coin reject section towards the second coin exit opening. A gate assembly is movably disposed in a portion of the coin path for blocking movement of a coin through the coin receiving section of the coin path in one position and directing the coin into the coin reject section; or for permitting movement of the coin into and through the coin receiving section while blocking movement of the coin through the coin reject section.

摘要： A coin selection device is of a type in which reference voltage is automatically adjusted in accordance with variation in the output level of a receiving coil in a standby mode. A oscillating coil and a receiving coil are disposed on both sides of a coin path. A peak of output level of the receiving coil and the reference voltage are compared each other in a comparator for detecting whether inserted coin is true or false. The output level of the receiving coil in the standby mode is stored so that variations in temperature and circuit parameters can be taken into account in the reference voltage level.

摘要： A coin testing apparatus (10) comprises a coin passageway, a coin track (13) along which coins pass on their edges through the coin passageway and an inductor (16) adjacent the coin passageway. The inductor is connected in an oscillating circuit (40) so that the inductor (16) produces an oscillating magnetic field in the coin passageway. The frequency of the oscillating circuit is measured using a counter (41). A number representative of the idle frequency is stored in register (44). When a coin passes the inductor (16), the apparatus (10) detects whether the resulting frequency shift corresponds to the shift for an acceptable coin by comparing the difference between the number stored in register (44) and the number stored in counter (41) with a number previously stored in memory (48). The inductor (16) is oblong and has its major axis perpendicular to the track so that the arrangement is sensitive to variations in diameter over a large range of diameters.

摘要： A method and an apparatus for testing and identifying electrically conductive discs, such as coins or equivalent. According to the method the effect of each coin on a magnetic field generated by means of coils is measured, the measurement result obtained in this way is compared with the reference value, and the coin is accepted if the measured value is close enough to the reference value. The reference value is determined on the basis of the effect produced by a preselected reference coin upon a magnetic field preferably of the same magnitude as the magnetic field to be measured. The magnitude of the magnetic field is measured in two directions at least substantially perpendicular to each other and the effect of the coin upon the symmetry of the magnetic field to be measured is taken into account by means of an additional coil placed at least substantially in the symmetry plane of the magnetic field to be measured.

摘要： A coin receiving apparatus for a vending machine capable of accurately checking a coin diameter as well as other coin characteristics such as material and a surface pattern for discriminating a true coin from a false one and receiving the former and rejecting the latter. The diameter and other coin characteristics are detected by examining peak values of output waveshapes of coin detectors by means of a window circuit. A single window circuit is provided for each denomination and upper and lower limit values of the window circuit are automatically changed in accordance with a coin characteristic under examination. Frequencies of excitation signals of the various coin detectors are also automatically changed. If a plurality of coins are successively inserted in the coin receiving apparatus without a sufficient time interval, discrimination of the inserted coins is inhibited and the inserted coins are returned.
