Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine,
The present invention relates to a currency identification device provided in a currency exchange machine, a coin game machine, and the like, for identifying the authenticity and type of inserted bills or coins. 2. Description of the Related Art As a currency discriminating apparatus of this kind, for example, there is a coin discriminating apparatus disclosed in Japanese Patent Publication No. 56-513965. This coin identification device stores in advance a reference identification data, which is a reference for each element, in a memory for each type of coin for each determination element such as a material, thickness, and external dimensions of the coin, and outputs an oscillating magnetic field to the inserted coin. Is applied and the change in the oscillating magnetic field at that time is detected, and this detection data is compared with all the stored reference identification data one after another, and when it matches with any one of the denomination reference identification data, If it does not match any of the stored reference identification data, it is discharged as a fake coin outside the apparatus. [0003] In recent years, however, foreign coins very similar to Japanese coins are sometimes used in coin discriminating apparatuses mounted on vending machines in the market.
For this type of foreign coins, the allowable range of identification based on the characteristics of coins for coin identification partially overlaps with the allowable range of Japanese coins. If the allowable range of the identification data is narrowed, there is a problem that the coin identification device becomes difficult to accept a genuine coin. On the other hand, it is known that the frequency at which such foreign coins are used depends on the installation environment such as the area where vending machines are installed and indoors and outdoors. Therefore, in the conventional vending machine, the reference identification data of two wide and narrow identification allowable ranges are stored in advance for each denomination, and the reference identification data is switched according to the area or environment where the reference is installed. The coins are configured so that the standard for identifying coins can be strict or loose. However, if the criteria for identifying coins are too strict,
A situation has arisen in which more coins are returned, and some vending machine managers do not like such situations. For this reason, a plurality of characteristic data in which the allowable range of identification is changed stepwise is stored, and a plurality of setting switches corresponding to each identification data are provided, and the setting of the reference identification data is performed by ON / OFF of each setting switch. There is also a coin discriminating device that is configured to be able to perform it in a meticulous manner. [0005] However, when the number of identification data is increased, the number of setting switches and LEDs used for setting the identification data increases accordingly, which not only raises the cost of parts, but also increases the layout. Also needs a lot of space.
For this reason, when the number of components operated at the time of setting increases, the operation becomes complicated and difficult to understand, and it is actually difficult to perform the switching operation of the identification standard at the installation location of the vending machine. turn into. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a currency discriminating apparatus which can easily and surely set a currency discrimination standard, and can reduce cost and space. The purpose is to: [0007] In order to solve the above-mentioned object,

A coin identification processing unit 12 for performing processing such as coin identification. The first, second, and third sensors 5, 6, and 7 each generate an oscillating magnetic field at a predetermined frequency, and detect a change in the oscillating magnetic field caused by an eddy current generated in the coin when the coin passes. Alternatively, it is output as a sensor signal that represents a characteristic characteristic of the coin by capturing the voltage value. The characteristics of the coin are, for example, material, thickness, outer dimensions, and the like.
The frequency, shape, and arrangement position of the second sensor 6 are determined so that the thickness can be sensitively sensed for the second sensor 6 and the third sensor 7 can be sensitively sensed for the external dimensions. Next, the operation of the coin discriminating apparatus 1 will be briefly described. When the coin 2 is inserted into the coin insertion slot 3, the coin 2 moves along the rolling surface of the coin passage 4 inside the coin discriminating apparatus 1. Roll to When the coin 2 reaches the position of the first, second and third sensors 5, 6, 7 the three sensors 5, 6, 7

Then, the control unit 12 determines whether the coin 2 is true or false and the type of the coin 2 by determining whether or not the detection data generated from each sensor signal is within the numerical range of the reference data stored in advance. When the coin 2 is identified as a proper coin, the coin identification processing unit 12 opens the coin passing gate 8 and
The coin 2 is stored in a coin storage (not shown) via the appropriate coin receiving passage 9. On the other hand, when it is determined that the coin 2 is not appropriate, the coin identification processing unit 12 returns the coin 2 via the return passage 9. And coin currency gate 8
Is passed by the coin 2, the passage sensor 10 detects the passage of the coin 2, and a passing signal is output to the coin identification processing unit 12. When the passing signal is input, the coin identification processing unit 12 sends out a proper coin signal to the outside of the present apparatus 1 and ends the predetermined coin processing. Next, the electric circuit of the apparatus 1 will be described with reference to FIG.

The components shown in the figure are mainly built in the coin identification processing unit 12, and the reference numeral 20 shown in the figure designates a setting unit, an operation unit, and a microcomputer (a microcomputer for identifying the authenticity and type of coins, etc.). The input port of the CPU 20 is provided with digital data as detection data by using magnetic data detected by the first sensor 5, the second sensor 6, the third sensor 7, and the passage sensor 10, respectively. Detection processing circuits 21 and 22 for converting the signals into signals;
23 and a gate processing circuit 24 are connected to each other. Further, a setting switch (designating means) 25 and a confirmation switch 26 described later are connected to each other. A gate processing circuit 27 for opening and closing the coin passage gate 8, a buzzer 28, and a monitor LED 29 are connected to an output port of the CPU 20, and input / output ports of the CPU 20 serve as candidates for reference identification data. A memory unit (storage unit) 30 for storing a plurality of identification data corresponding to each of the sensors 5, 6, 7 is connected to each of the sensors. The detection processing circuit 21,
22 and 23 are three sensors 5 with coin 2 being inserted.
The sensor signal output from each of the amplifiers 6 and 7 is amplified to a predetermined amplitude, the waveform is shaped by a built-in clip circuit, the waveform is shaped, and output to the CPU 20 as detection data via an A / D conversion circuit. The setting switch 25 is for setting a setting mode for setting reference identification data, and the confirmation switch 26 is for confirming the setting contents of the reference identification data. The memory unit 30 previously stores a plurality of identification data for determining an acceptance reference range for each characteristic of the material, thickness, and external dimensions of the coin, and the CPU 20 stores a predetermined address of the memory unit 30 in a predetermined address. By accessing, necessary identification data is read out, and the CPU 2
0 is stored as reference identification data in the built-in RAM. FIG. 3 schematically shows the contents stored in the memory unit 30. Each of the accepted denominations A to D (10 yen, 50 yen)
5) corresponding storage areas 30a, 30b, 3
0c and 30d, and each of these storage areas corresponds to the sensors 5, 6, and 7, and has three storage units S1, S2, and S3.
And these storage units S1, S2 and S3 have a to g
Up to seven types of identification data are stored. The identification data in this example is composed of upper limit value data (MAX) and lower limit value data (MIN), and the identification criterion becomes weaker from a to g. More specifically, for example, denomination A will be described. Identification data having the strictest discrimination criteria for detection data obtained by generating sensor signals obtained from the sensors 5, 6, and 7 of denomination A Are the values S1AA1
1, the value S2AA11, and the value S3AA11, and the lower limit values are the value S1AA12, the value S2AA12, and the value S3AA, respectively.
Twelve. That is, in the case of the identification criterion A, each sensor 5,
When the detection data of the sixth and seventh detection data is between the upper limit value and the lower limit value, the denomination A is identified. The same applies to denominations B to D. The gate processing circuit 27 as a constituent element
Controls the opening and closing of the coin passage gate 8 based on the gate control signal from the CPU 20 when the inserted coin 2 is determined to be appropriate. Next, the operation of the CPU 20 in the setting mode and the confirmation mode will be mainly described. First, the setting of the reference identification data in the setting mode will be described. When the setting switch 25 is turned on, a setting mode is set. In this state, coins of the denomination whose reference identification data is to be changed are inserted by the number corresponding to the identification references A to E. After identifying the denomination of the inserted coins, the CPU 20 counts the number of inserted coins by an internal denomination set number counter. It is to be noted that a specific association is previously established between the number of inserted sheets and the identification criterion. If the number of inserted sheets is one, the identification criterion a is used. , The identification criterion c for four, the identification criterion d for five, the identification criterion f for five, the identification criterion f for six, and the identification criterion for seven. To g, 8
When the number of coins is more than one, the coins are associated with each other so that the acceptance of the inserted coins is prohibited. When a predetermined number of coins have been inserted, the setting switch 25 is turned off.
F or after a certain period of time, the CPU 20
The identification data corresponding to the count value is read from the memory unit 30, and the reference identification data storage unit 20 in the internal RAM is read.
a, and this identification data is used as reference identification data. FIG. 4 shows the reference identification data storage section 20a.
Schematically shows the storage contents of the reference identification data storage areas 201 to 20 corresponding to the denominations A to D.
4 is provided. The operation of writing the reference identification data into the storage unit 20a will be specifically described with reference to FIG. FIG.
FIG. 5 is a diagram for explaining the operation of a denomination set number counter 20b used as a pointer to the memory unit 30 when reading specific identification data from the memory unit 30 and writing it as reference identification data in the reference identification data storage unit 20a. is there. The counter 20b is provided in the internal RAM of the CPU 20, but its count value is set to 2 at the time of factory shipment so that all denominations are set to the identification reference b. In this state, when the setting standard is changed for the denominations A and D, one sheet is inserted for the A denomination and three sheets are input for the D denomination, and the count values of the A denomination counter 211 and the D denomination counter 214 become respectively. "1" and "3". The CPU 20 reads the identification data of a stored in the storage units S1, S2, and S3 of the storage area 30a in the memory unit 30 according to the count value "1" of the A denomination counter 211, and reads this. The data is written in the reference identification data storage area 201 of the reference identification data storage unit 20a. Further, the CPU 20 reads the identification data of c stored in the storage units S1, S2, and S3 of the storage area 30d in the memory unit 30 according to the count value “3” of the D denomination counter 211, and uses this as a reference. The data is written into the reference identification data storage area 204 of the identification data storage unit 20a. However,
Regarding the denominations B and C, there is no coin inserted and the denomination counters 212 and 213 are “0”, so that the reference identification data storage areas 202 and 203 of the reference identification data storage unit 20a have It is held at the factory setting standard b. Next, the operation of the CPU 20 in the confirmation mode will be described with reference to FIG. When the confirmation switch 26 is turned on and a coin of the denomination A is inserted, the CPU
20 identifies the denomination of the inserted coin 2 as denomination A,
The identification criterion set for the denomination A is displayed by the buzzer 28 and the monitor LED 29. In particular,
When the denomination A is set as the identification standard A, FIG.
As shown in (a), a pulse having a pulse width of time T1 and a cycle of time TX is output three times repeatedly, and the buzzer 28 utters for the time of the pulse width, and the monitor LED
29 lights up. Note that the period of the pulse signal is set to a time sufficiently longer than the pulse width time, for example, three times or more, so that it is easy to confirm. Similarly, as shown in FIGS. 3B and 3C, when the identification criterion is B and C, the pulse signals having periods of TX ′ and TX ″ are 3 respectively.
The pulse signal is output twice and three times in each cycle. Further, the cycle of the pulse signal in each cycle is time (T1 + T2). When the identification criteria are D and E, the pulse signal is output four times and five times in one cycle. Next, the identification operation of the CPU 20 will be described. For example, when a coin 2 of denomination A is inserted and passes through each of the sensors 5, 6, and 7, each of the sensors 5, 6, and 7 outputs a sensor signal to the detection processing circuits 21, 22, and 23, and each of the detection processing circuits 21, 22 and 23 transmit the detected data to the CPU 20.
Output to The CPU 20 determines that the input detection data is
It is determined whether the reference identification data for each denomination with respect to each of the sensors 5, 6, and 7 stored in the reference identification data storage unit 20a of the internal RAM is within the range of the upper limit value and the lower limit value. CP
U20 identifies the coin 2 as a denomination A coin if the detected data is within the numerical range of the reference identification data of the coin A, and otherwise judges the coin 2 as a fake coin and returns the coin to the return passage. 1
Return from 1. As described above, according to the present embodiment, after turning on the setting switch 25, coins of a denomination whose number is to be set by the number corresponding to the identification criterion are inserted, which becomes a reference for coin identification. The setting of the reference identification data is completed.
For this reason, not only can anyone easily set, but also the identification criterion to be set based on the number of coins to be inserted is known. be able to. Also, when confirming the set identification criteria, it is only necessary to insert a coin for which the identification criteria are to be known, so that it is easy, reliable, and
It is easy to understand. In addition, since it is only necessary to store the program in advance, the number of parts to be used can be reduced, the cost can be reduced, and the space can be saved. The present invention is not limited to the above embodiment. For example, the usage of the currency identification device 1 is not limited to a vending machine, but can be widely applied to a currency identification device such as a currency exchange machine and a game machine. Money also includes banknotes and coins. In the present embodiment, the identification criterion is described as a currency acceptance criterion, but the present invention is also applicable to a case where a currency ejection criterion is determined. Further, the identification reference data is not limited to the types and numbers described in the present embodiment. For example, in the case of a bill, the type may be pattern or ink characteristic data, or a correlated determination element based on magnetic data detected from a plurality of sensors may be added. Further, in this embodiment, the switches for setting the mode and the confirmation mode are provided, respectively. However, the present invention is not limited to this. The setting and confirmation may be performed by providing and counting the number of money inserted from here. As described above, according to the currency discriminating apparatus of the present invention, a predetermined number of coins for setting the reference discriminating data are automatically inputted to perform the reference discriminating data. Data can be set easily and reliably, and furthermore, cost reduction and space saving can be achieved. Also set
