Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic currency exchange device capable of converting input coins of a single denomination or multiple denominations into coins of multiple denominations.
After converting to the desired exchange denomination based on the above input currency,
The present invention relates to an automatic currency exchange device that can automatically exchange the remaining amount into currency of a predetermined denomination.

Financial institutions such as banks that handle a large amount of various types of currency exchange currency of a single denomination or multiple denominations (especially large denominations) into small denominations of multiple denominations. It would be very troublesome and inefficient for bank staff to exchange money each time, and for this reason, automatic currency exchange machines that have a currency exchange function that automatically performs currency exchange operations have recently been introduced. It has been developed and put into practical use.

This automatic exchange device operates the operation unit after inserting high-value paper of a single denomination or multiple denominations such as 10,000 yen bills, 5,000 yen bills, 1,000 yen bills, etc., into the input slot. You can automatically exchange small denomination coins such as 1,000 yen bills, 500 yen bills, 100 yen coins, etc. by specifying the denomination, number of coins, or amount. However, in conventional devices of this type, when the specified total amount matches the input total amount, a counting operation is started and small denomination coins of each specified denomination are inputted into the withdrawal slot. Therefore, with this type of automatic exchange device, money cannot be exchanged unless the specified total amount reaches the total amount inserted. Even if you wish to exchange the remaining amount, but there is no need to specify a denomination for the remaining amount, you will not be able to exchange the remaining amount unless you specify some kind of denomination. This is very troublesome, and also has drawbacks such as lowering the operating rate of the exchange machine during busy times. The present invention has been made in view of the above circumstances, and its purpose is to provide an automatic currency exchange device capable of converting input coins of a single denomination or multiple denominations into coins of multiple denominations. After specifying the desired exchange denomination based on the input amount, and operating the balance operation switch, the balance obtained by subtracting the specified exchange amount from the input amount will be automatically paid using the predetermined amount. This feature is particularly useful when you want to specify the denomination and exchange only a portion of the total amount of coins you have input. It provides a currency exchange device.

If e is pressed and the shutter of the ejection port 81 is opened to take out the coins, the shutter is closed after a predetermined period of time has elapsed, and all the registers RRI to SR are reset at the same time. For example, the operation of the automatic currency exchange device of the present invention having the above-described configuration can be explained as follows. Books (total amount 2
We will explain the case where you exchange the money to 1,550,000 yen) and pay the remaining amount of 4,500 yen by pressing the withdrawal button.

First, it is assumed that input register 9 and registers RRI to SR are automatically reset when the power is turned on. When the first 10,000 yen bill is inserted through the paper input slot 80, a motor provided at the back of the input slot 80 automatically starts rotating and introduces the 10,000 yen bill into the discriminating section 1. The authenticity of the 10,000 yen bill is determined in the discrimination section 1. In the case of a defective paper such as a counterfeit bill, the discrimination section 1 rotates the motor in the reverse direction, returns the paper to the input slot, and performs the exchange operation. prohibit. If the paper is normal, the discriminator 1 sends a normal discriminator signal indicating a 10,000 yen bill to the timing pulse generator 2. As a result, each part of the circuit shown in FIG. 2 performs the following operation under the control of the timing pulse generator 2. First, the gate circuit 10 supplies the contents of the register RRI (in this case, "0") and the contents "1" of the portion 8a of the numerical value generating circuit 8 to the calculation unit 5, respectively.

Further, the four arithmetic operation selection section 4 outputs an addition command e to the calculation section 5. The arithmetic unit 5 adds the content "0" of the register RRI and the content "1" of the portion 8a, and supplies the addition result "1" to the gate circuit 11. The gate circuit 11 supplies the combined data "1" to the register RRI and stores it there. Data “1” stored in register RRI
is displayed on the display section 30. Next, the contents of the gate circuit 1 register TRI (in this case, "0") and the contents "n0000" of the portion 8b of the numerical value generating circuit 8 are combined to the arithmetic unit 5. At this time, the four arithmetic operation selection unit 4 outputs the addition command e,
is subsequently output to the arithmetic unit 5. The content of the register TRI in the arithmetic unit 5 is “0” and the content of the portion 8b is “10000”.
and add this addition result "10000" to gate circuit 1.
Output to 1. The gate circuit 11 receives the data “10000
" is sent to register TRI and stored there. The data “10000” stored in the register TRI is displayed on the display unit 3.
The river is displayed. Next, the gate circuit 10 is connected to the resistor T.
The content of RI (in this case, n0000") and the content "1000" of the portion 8e of the numerical value generation circuit 8 are sent to the calculation section 5, and the four arithmetic operation selection section 4 sends the division command e4 to the calculation section 5.
Output to. The arithmetic unit 5 converts the contents of register TRI to “10
000" is divided by the content "1000" of the portion 8e, and the division result "10" is supplied to the gate circuit 11. The gate circuit 11 transfers the supplied data “10” to the register DRI.
Output to and store here. Output to register DRI and store there. The data "10" stored in the register DRI is displayed on the display section 3. Similarly, the contents of register TRI n000OJ and the numerical value generation circuit 8
Based on the contents "500", "5000", and "2500", the calculation unit 5 calculates 10000÷500=20
・・・・・・'1}10000÷
5000=2 ・・・・・・{2110
000÷2500=4...'3'
10000÷500=20...
. . . [41 operations are performed sequentially, and the results of these operations "20", "2", "4", and "20" are supplied to registers DR2 to DR5 and stored, respectively. Further, the contents of each register DR2 to DR5 are displayed on three display sections. Therefore, when all of the above operations are completed, the contents of registers RR1, DRI to DR5, and TRI are - RRI: "1" DR4: "4" DRI: no
” DR5: “20” DR2: “20” TRI: “10000” DR3:
It becomes "2".

In this case, the contents of register RRI indicate that one 10,000 yen bill has been inserted, and the contents of registers DRI to DR5 respectively indicate that if the inserted 10,000 yen bill is a 1,000 yen bill, it is lq woman, 500 yen. It shows that banknotes can be exchanged into 2 coins, 100 yen coins can be exchanged into 2 coins, 5 Nq coins can be exchanged into 4 coins, and 1 bowl coins can be exchanged into 20 coins, and the contents of the register TRI indicate that the current total amount of money inserted is 10,000 yen. It shows that. Next, when the second and third 10,000 yen bills are sequentially inserted into the paper input slot 80, the same operation as described above is repeated each time the bills are inserted.

Then, when the third 10,000 yen bill has been inserted, the contents of registers RR1, DRI to DR5, and TRI are as follows.
RRI: "3" DR4: "12" DRI: "30"
DR5: "60" DR2: "60" TRI: "30000" DR3:
"6", and each of these data is displayed on the display section 30'.

In this case, the contents of registers RRI to SR other than the upper register are all "0".

Also, in the above example, three 10,000 yen bills were inserted,
For example, if you insert one 10,000 yen bill and one 5,000 yen bill, the contents of register RRI and register RR2 will each become "1", and if you insert only 5,000 yen bills, for example, In this case, the contents of register RR3 become "5". Of course, in these cases, the contents of the other registers DRI to TRI will change accordingly. After inserting the three 10,000 yen bills, the customer then specifies the exchange denomination and the number of coins to be exchanged. First, the customer uses the operating nails 3a and 3b of the operating section 3 to insert the 1,000 yen bill. When the fork is specified, a signal indicating a thousand yen bill is output from the operation section 3 to the timing pulse generating section 2, and the number of thousand yen bills "10" is also supplied to the input register 9 and stored there.

When a signal indicating a thousand yen bill is supplied to the timing pulse generator 2, each part of the circuit performs the following operations under the control of the timing pulse generator 2. First, the gate circuit 10 supplies the contents of the register CRI (in this case, "0") and the contents of the input register 9 (in this case, "10") to the calculation section 5, and the four arithmetic operation selection section 4 adds A command e is output to the calculation section 5.

The arithmetic unit 5 adds the content "0" of the register CRI and the content n0 of the input register 9, and supplies the addition result "10" to the gate circuit 11. The gate circuit 11 sends the supplied data "10" to the register CRI and stores it there. The data n0 stored in the register CRI is displayed on the display section 301. Next, the gate circuit 10 supplies the contents of the input register 9 (“10” in this case) and the contents “1000” (corresponding to a thousand yen bill) of the portion 8e of the numerical value generating circuit 8 to the calculation unit 5, and , the arithmetic operation selection unit 4 outputs the multiplication command e3 to the calculation unit 5. The arithmetic unit 5 inputs the content "10" of the input register 9 and the content "1000" of the portion 8e.
The gate circuit 11 calculates the multiplication result n0000.
Output to. The gate circuit 11 receives the supplied data “10
000" to the sub-register SR and store it there. Next, the contents "30000" of the register TRI and the contents "10000" of the sub-register SR are sent to the calculation section 5 via the gate circuit 10, and the subtraction command e2 is outputted from the four arithmetic operation selection section 4 to the calculation section 5. Ru.

The arithmetic unit 5 subtracts the content "10000" of the register SR from the content "30000" of the register TRI, and supplies the subtraction result "20000" to the register TRI via the gate circuit 11 to be stored. Here, register TRI
The content "20000" indicates that the amount that can be exchanged thereafter is 20,000 yen. Next, the arithmetic unit 5 registers the register T.
Based on the content "20000" of the RI and the value of Taniuchi of the numerical value generation circuit 8, the following calculations are performed. 20000÷10
00=20...[512

1 And these calculation results “20”, “40t”4↓
Send "8↓"40" to registers DRI to DR5, respectively,
Make me remember.

In this case, the stored contents of the registers DRI to DR5 each indicate the number of coins of each denomination that can be exchanged for the remaining amount of 20,000 yen at this point. Next, the customer
When three IONq coins are designated by the operation nails 3a and 3b, a signal indicating 10 q coins is output from the operation unit 3 to the timing pulse generator 2, and the number of 100 yen coins "3" is input to the input register 9. It will be combined and stored here.

Thereafter, under the control of the timing pulse generation circuit 2, each part of the circuit operates in the same manner as described above, and as a result of this operation, the contents of the registers DRI to TRI become as follows. DRI
: "5" CRI: "10" DR2: n0" CR2: "0" DR3: "1" CR3: "3" DR4: "2" CR4: "0" DR5: "10" CR5: "0" TRI: "5000" Here, the contents of registers DRI to DR5 each indicate the number of coins of each denomination that can be exchanged for the remaining amount of 5,000 yen at this point, and the contents of registers CRI and CR3 each indicate 1,000 yen. This indicates that the exchange of 10 yen bills and 3 100 yen coins has been specified, and the contents of the register TRI indicate that the remaining amount at this point is 5,000 yen.

Next, when one 15 q coin is specified, the same operation as in the above case is performed again, and each register DRI to TRI is
The contents of each are as follows.

DRI: "4" CRI: "10" DR2: "9"
CR2: "0" DR3: "0" CR3: "3" DR4: "1" CR4: "0" DR5: "9" CR5: "1" TRI: "4500" The operation of each part of the circuit is based on the specification of the number of coins (books).In the above operations, all the data input to the input register 9 is within the payable number of coins (books), so the error detection circuit 6 detects an error. will not be detected.

Next, when the customer presses the coin amount payout button 3c, the number of exchange coins (units) for the remaining amount (in this case, 450qq) is determined in order from the highest amount to the highest exchange currency, and the determined number of coins (units) is is the number of coins (pieces) of each denomination specified by the operator (CRI
~Contents of CR5). Then, based on this addition result, the exchange currency is paid out. The above operation will be explained in detail below with reference to FIG.

FIG. 3 is a diagram that extracts the parts related to the above operation from the circuit shown in FIG. 2 and further shows each extracted part in detail. A code is attached.

In FIG. 3, a pulse generator 2a in the timing pulse generator 2 is a circuit that outputs the reference pulses PI to P7 shown in FIG. 4 and the write timing signal W shown in the same figure.

Further, when the calculation cycle generation circuit 2M is supplied with the operation signal a that is output when the remaining amount payout button 3c of the operation section 3 is pressed, a pulse corresponding to one cycle of the reference pulse P7 is generated as shown in FIG. This circuit outputs a pulse signal n having a width. When the remaining amount payout button 3c is pressed, a pulse signal n is output from the calculation cycle generation circuit 2b, and as a result, timing pulses q, -q6 shown in FIG. 5 are output from the AND gates 41-46.

Then, the AND gate 47 is activated by the timing pulse q.
, 52 are opened, the contents "10" of the register CRI and the contents "4" of the register DRI are sent to the 0 operation unit 5 via the OR gate 57 or OR gate 58, respectively. Also, at the same time, the timing pulse q, is calculated by the four arithmetic operation selection section 4.
The addition command signals e,
is output and sent to the calculation section 5. Therefore, the calculation unit 5
Then, the addition of the above data “10” and “4” is executed,
The calculation result “14” is sent to the AND gate 60.
By the way, at this time, since the timing pulse q6 is not output, the output via the inverter 59 is in the logic state of "1", and therefore the AND gate 60 is opened and the above calculation result r14 is output. On the other hand, since the AND gate 66 receives the timing pulse q and the write timing signal W as input signals, the logical product q. - A write signal synchronized with the pulse signal W is sent to the register CRI at timing W, and the calculation result "14" output from the AND gate 60 is newly written to the register CRI. Next, when timing pulse q2 is output, AND gates 48 and 53 are both opened and the content of register DRI is "4".
The numerical value "1000" is sent from the portion 8e of the numerical value generating circuit 8 to the arithmetic unit 5 via the OR gate 57 or 58, respectively.

Since the calculation unit 5 receives the multiplication command signal e3 output from the four arithmetic operation selection unit 4 which received the timing pulse q2 at the same time, the calculation unit 5 inputs the data “4” and “1000”. Multiplication is executed, and the result is “400
0'' is output to the AND gate 60. At this time, since the output of the inverter 59 is in the logic state of "1", the above operation result "4000" is output from the AND gate 60 and written to the sub-register SR at the timing of the logical product q2.W. Next, when timing pulse q3 is output, AND gates 49 and 54 are opened, and the contents of register TRI and sub-register SR are ``4500'' and 4000, respectively.
'' are sent to the arithmetic unit 5 via OR gates 57 and 58, respectively. Since the timing signal q3 is also sent to the four arithmetic operation selection section 4, the subtraction command e is sent from the four arithmetic operation selection section 4.
2 is output and sent to the calculation section 5. Therefore, in the calculation section 5, based on the above input data, "5000" is calculated.
- The calculation of "4500" = "500" is executed, and the calculation result "500" is output from the AND gate 60'. Then, this calculation result "500" is written to the register TRI at timing q3,W. Next, when the timing pulse q4 is output, the AND gates 50 and 55 are both opened, and the content "500" of the register TRI and the numerical value "500" of the portion 8f of the numerical value generating circuit 8 are output to the OR gate 57.
or 58 to the arithmetic unit 5, and at the same time, the four arithmetic operation selection unit 4 outputs the division command signal line 4 to the arithmetic unit 5. As a result, the calculation section 5 performs division (500÷500), and the calculation result "1" (that is, the number of 50 sheets of paper to be paid out) is output to the AND gate 60. This operation result "1" is written to the sub-register SR at timing q4,W. Next, when the timing signal q5 is output, the AND gates 51 and 56 are opened, and the contents of the register CR2 are "01" and the sub-register SR
The content "1" is sent to the arithmetic unit 5 via the OR gate 57 or 58, respectively.

At this time, since the addition command signal e is output from the arithmetic operation selection section 4 to the calculation section 5, the addition of (100) is executed in the calculation section 5. The calculation result “1” is q5
, W, and is written to register CR2 at the timing of 50
The number of q paper sheets can be rewritten. Next, when the timing pulse q6 is output, the gate of the AND gate 60 is closed via the inverter 59, so its output signal becomes a "0" signal, and the AND gates 61 to 65 .
68 and 69 are each in an open state. As a result, the output signal "0" of the AND gate 60 is written into the registers DRI to DR5, TR1, and SR at timings q5 and W, respectively, and all of these registers are reset. In this case, registers CRI to CR5 each contain data “14” and
"1", "3", "0", and "1" are held. Thus, when the register TRI is reset, the zero detection section 28 shown in FIG. 2 detects this and sends a counting start signal to the counting section 29.

The counting section 29 immediately starts counting operation, and register CRI
~ Perform counting operations until they match the contents of CR5, that is, the data for each denomination, and count the counted coins (i.e., 14 1,000 yen bills, 1 500 yen bill, 3 100 yen coins, 1 q One coin) is discharged to the outlet 81, and the counted total amount is sent to the register TR2 to be stored and displayed on the display section 30. The customer confirms the counted total amount (contents of Regis TR2: 30,000 yen) by looking at the display section 30, and if it matches the input amount, presses the confirmation operation nail 3e. This pressing operation opens the shutter of the currency withdrawal port 81, and when the customer takes out the exchanged money, the shutter closes after a predetermined period of time and at the same time outputs a clear signal that clears the contents of all registers RRI to SR. , to return to the initial state. In this way, when the remaining amount dispensing nail 3c is pressed, under the control of the timing pulse generator 2, first, the highest denomination of 1,000 yen among the exchangeable denominations (1,000 yen to 1 q) is exchanged. The possible number of coins (the number of coins that can be exchanged for the remaining amount of 450 folds, that is, the contents of the register DRI) is added to the contents of the register CRI, and then the amount of 4,000 yen corresponding to the number of 1,000 yen bills added to the register CRI is added to the remaining amount of 4,500 yen. Then, based on the result of this subtraction, the number of exchangeable coins of the next highest denomination of 500 yen is determined, and this determined number is added to the register CR2.

In this embodiment, there are three denominations to be exchanged: 1,000 yen, 5,000 yen, and 10,000 yen, and the minimum unit of exchange amount is 500 yen (one 10 yen coin).

Therefore, the exchange denominations to be determined based on the operation of the balance payout button 3c are only two types: 1,000 yen bill and 50Gq bill. In addition, in the above-described operation, for example, if the remaining amount at the time when the remaining amount dispensing nail 3c is pressed is an integral multiple of 1,000 yen, the contents of the register TRI become "0" at the timing of q3, W.

In this case, the zero detection section 28 outputs a counting start signal at this point and instructs the counting section 29 to perform a counting operation. As explained in detail above, the present invention provides an automatic currency exchange device capable of converting input coins of a single denomination or multiple denominations into coins of multiple denominations. After specifying the desired exchange denomination and amount, if you operate the operation switch for the balance, the specified exchange amount will be subtracted from the input amount, and the exchange currency amount for the remaining amount will be determined in order from the highest value to the highest amount. It is characterized by the fact that it is paid to

Therefore, you can only specify the denomination and amount you wish to exchange, and then change the rest by simply operating the operation button for the balance. To make the exchange operation very easy and quick when there is no problem with other denominations, and to make the automatic exchange operation efficient.
