The invention provides a money sorting method and unit that can detect such a counterfeit as foreign money for which material, outer diameter and other features are very similar to a genuine coin, and that can decrease damage caused by the continuous trial of entry of counterfeit money. Sensors detect the material of a coin entered from a coin entry section, and at the same time, the outer diameter of the coin is detected by three sensors with a highly accurate method utilizing time ratio, pattern on the surface of the rolling coin is detected by converting output of the sensors to a basic pattern, and genuineness of the entered coin is judged based on these detection results. Detection detects features of the money entered from the money entry section based on output of the feature sensor, comparison judges whether the entered money is genuine or counterfeit, and if the entered money is a counterfeit, the counterfeit money is returned and at the same time an acceptance prohibition timer is activated, and while the acceptance prohibition timer is operating, acceptance is rejected whether the entered money is genuine or counterfeit.

Money screening method and unit

Distributed processing unit

Distributed processing unit connectable to external processing means

A coin mech controller (70), when receiving a coin payment set command from a main controller (10), judges the presence or absence of a coin within an acceptor (100). In the absence of a coin within the acceptor (100), the coin mech controller (70) controls to immediately pay out coins corresponding to a coin payment amount calculated by the main controller (10). In the presence of a coin within the acceptor (100), the coin mech controller (70) controls to pay out coins corresponding to the coin payment amount calculated by the main controller (10) after the coin within the acceptor (100) has passed through. The coin mech controller (70) determines the numbers of coins having different coin sorts and corresponding to the payment amount calculated by the main controller (10), sets a payment pattern of a coin sort priority corresponding to maximum one of the determined numbers of coins in different sorts, and controls a coin dispenser (220) of a coin mech body (200) according to the set payment pattern to pay out coins from coin tubes (210-1 to 210-4).

Coin processor

A coin payout device that has been improved such that a coin jam will be automatically dislodged in the event that a coin jam occurs, and there will be no problem of overpayment. When coin payout is performed by the forward rotation of a coin payout motor (40), a coin payout controller (80) detects the occurrence of a coin jam from the operational circumstances of a carrier switch (60) up to the time when a first timer (81) runs out, and determines whether the reverse rotation of the coin payout motor (40) would cause a problem based on the current state of the carrier switch (60), so that the coin payout motor (40) is reversed and the coin jam dislodged only when no problem will be caused.

Coin payout device

In a case where a succeeding coin has arrived at a coin discriminator (110) before a preceding coin passed through the coin discriminator (110) arrives at a disposition position of a true/false coin distributor (120), the true/false coin distributor (120) is shifted to a false coin side to distribute both of the preceding and succeeding coins to the false coin side. When the preceding coin passed through the coin discriminator (110) is true one and if the succeeding coin has already arrived at the coin discriminator (110) immediately after passage of the preceding coin through the true/false coin distributor (120), the true/false coin distributor (120) is shifted to the false coin side to distribute only the succeeding coin to the false coin side. When the preceding coin passed through the coin discriminator (110) is false one and if the succeeding coin has arrived at the coin discriminator (110) before the preceding coin passes through the true/false coin distributor (120), the true/false coin distributor (120) is shifted to the false coin side to distribute the succeeding coin to the false coin side.

A classification accuracy setting device and a method therefor of a coin selector used in an automatic vending machine, a money exchanger and other various automatic service apparatuses. In accordance with the operation of the device, a reed switch is turned on to set a classification accuracy selection mode, the number of coins of each denomination received in this mode is counted, and reference values of classification accuracies which have been stored in a memory are rewritten in response to the counted number.

Classification accuracy setting device for a coin selector

A coin to be judged is passed near an oscillation coil excited by an exciting signal containing a plurality of harmonic components, that is nonsinusoidal alternating current, and the coin is sorted in accordance with a signal produced by a receiving coil electromagnetically coupled with the oscillation coil and containing at least two harmonic components. The signal induced in the receiving coil may be a composite signal of at least two harmonic components. This signal may consist of a first signal of a composite of at least two harmonic components and a second signal of a composite of at least two other harmonic components.
