Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a control device for a vending machine that can use both coins and banknotes. It relates to making it possible to memorize information.

<Prior art> It is desirable to be able to use not only coins but also banknotes in vending machines that sell high-value items or that are expected to sell a large amount at one time due to continuous sales. preferable.

This is because inserting banknotes requires less effort than inserting multiple coins. In order to be able to handle banknotes, a banknote recognition device is installed in the vending machine, but in this case, when the sale is cancelled, or even if the sale is not canceled, a small purchase is made that does not lead to the redemption of the high-value banknote. In order to be able to return the inserted banknotes from time to time, a banknote identification device having a temporary holding function is used as the banknote identification device. Conventional banknote identification devices are generally capable of temporarily holding only one banknote.

<Problems to be solved by the invention> In the conventional system, only banknotes that have been temporarily held can be returned, and when a request for return is made, deposits up to the amount that cannot be returned are not accepted, so only one deposit can be returned. The number of banknotes that could be accepted for sale (purchase) corresponded to the number of banknotes that could be temporarily held. That is, in general, only one bill could be inserted per sale. Therefore, if one bill is not enough, additional coins must be inserted, which is troublesome.

This invention was made in view of the above points,
By making it possible to continuously insert more banknotes than can be temporarily held, a large amount of money can be easily inserted into multiple banknotes, saving the time and effort of inserting money and increasing the usage of the vending machine. The purpose is to increase.

<Means for Solving the Problems> A control device for a vending machine according to the present invention includes a counting storage means for counting and storing the inserted banknotes and coins by denomination, and a means for temporarily holding the inserted banknotes. and controls the counting storage means to exchange and store the value of the banknotes at the temporary holding position in units of coins of a predetermined lower denomination, and to collect the exchanged and stored banknotes from the temporary holding position into the interior. The present invention is characterized by comprising a currency exchange control means and a control means for controlling the refund based on the contents stored in the count storage means when making a refund.

<Function> The exchange control means exchanges and stores the input banknotes in units of coins of a predetermined lower denomination, and stores the exchanged and stored banknotes internally without holding them.

As a result, the banknote temporary storage position becomes vacant, allowing additional banknotes to be inserted, and it becomes possible to continuously input a plurality of banknotes in excess of the number of banknotes that can be temporarily held.

According to an embodiment of the present invention, more effective banknote continuous input control can be performed by converting and storing input banknotes in units of coins of predetermined lower denominations under certain conditions. can do. In one embodiment, the first inserted banknote is unconditionally exchanged and stored as a predetermined lower denomination coin and collected, and a temporary holding position is vacated to enable the insertion of the second banknote. . And 2
The first inserted banknote is not exchanged and stored, but is stored in units of banknotes, and is held at a temporary holding position until its disposition (whether the banknote is collected or refunded based on the sale) is confirmed. be done. the result,
It becomes possible to continuously insert two bills using a single bill holding type bill recognition device. In another embodiment,
The first inserted banknote is not exchanged and memorized immediately, but the second inputted banknote is exchanged and stored on the condition that the second banknote is inserted, and the second inputted banknote is received. Make it acceptable. That is, the previously inserted bill remains in the temporary holding position until the next bill is inserted, and on condition that the next bill is inserted, the previously inserted bill is exchanged, stored, and collected. In this way, when a refund is requested after inserting one bill, the inserted bill can be refunded from the temporary holding position, and it is also possible to continuously insert any number of bills. Note that the temporary holding position refers to a position where the banknotes at that position can be refunded or collected.

According to an embodiment of the present invention, an effective denomination is proposed as a hardened denomination with which the inserted banknote should be exchanged. Generally, there are many different denominations of coins, but the reality is that only certain denominations are used frequently as change coins. Assuming that the coin denomination to be exchanged and memorized is one frequently used as a change coin as mentioned above,
When a request for refund is made, it is necessary to pay out frequently used coins for the amount of banknotes, which may sometimes lead to a shortage of change.
On the other hand, coin denominations that are used infrequently as change tend to remain in vending machines, which can also be a factor in hindering the circulation of coins of the relevant denomination. Therefore, it is more convenient to use coin denominations for which the inserted banknotes are to be exchanged and stored, rather than coins that are used less frequently. For example, in Japan's currency system as of the filing date, the coin denominations most frequently used as change in vending machines are 10
It is a yen coin, and the lowest one is 100 coins. Assuming that the denomination of the banknote is a 1,000 yen coin, as of this filing date, it seems preferable to exchange and store the 1,000 yen coin as a 100 yen coin. In addition, as criteria for selecting exchange denominations,
It is also a good idea to consider the degree of circulation of each coin denomination. That is, if coins with low social circulation remain in a vending machine, the circulation of coins of the relevant denomination will be further hindered, which may also impede the operation of the vending machine, which is undesirable. Therefore, if the coin denomination to be exchanged and stored for the inserted banknote is a denomination with relatively low social circulation and a unit denomination relatively close to the unit denomination of the banknote, then This is advantageous in terms of promoting the operation of the vending machine and improving the operating efficiency of the vending machine. By the way,
It is planned that a 500 yen coin will be issued in the near future, and the number of 500 yen coins issued will initially be small compared to other coins, and therefore the circulation is expected to be low. If the 500 yen coin is used to store banknotes (for example, 1,000 yen) as exchange, it would be convenient to encourage the circulation of the new 500 yen coin.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the banknote identification device 10 stores the banknotes inserted through the banknote insertion slot 10A at a temporary holding position P.
1 function, a function to feed the drawn banknotes to the insertion slot 10A to return them, and a function to draw the drawn banknotes further into the storage CBX, as well as bill temporary storage and transfer functions, and the authenticity of the inserted banknotes. This includes functions such as determining the The coin changer device 11 has a function of sorting coins input from an input slot (not shown);
A function to add and count the input amount of specie coins (including coins and banknotes) and subtract and count the price of sold products and the amount of coins paid out, a function to determine whether sales are possible based on the input amount and sales set price, etc. It includes a function to control the payout of banknotes and various other functions.

First, the general control function of the coin changer device 11 will be explained. Coin detection part SW500
SW10 to SW10 detect the inserted coins (sorted specie coins) by denomination and generate counting pulses corresponding to the denominations. For example, SW500 detects 500 coins.
SW50 corresponds to a 50 yen coin, and SW10 corresponds to a 10 yen coin. Counting pulses output from the detection units SW500 to SW10 in accordance with the denomination of the inserted coin are given to the amount counting unit 21. The amount counting section 21 adds and counts the total amount of coins and banknotes that have been inserted, and subtracts and counts the set price of the sold product or the amount of paid out money from this total amount of input. This amount counting section 21 is
Addition and subtraction registers ASR1 to ASR4 for each coin amount
and an addition/subtraction register corresponding to the denomination of the banknote (for example, 1000 yen coin) identified by the banknote recognition device 10.
It includes an ASR 5 and a summation circuit 21A. Each addition/subtraction register ASR1 to ASR5 adds or subtracts the count pulse given to the count input (CI) depending on the state (“1” or “0”) of the control signal given to the addition/subtraction control input (A/S). The counting results are stored and retained. Each coin detector SW500 to SW10 is used for count input (CI)
or the output of the banknote identification device 10 or the output of the collection and bill dispensing control unit 26,
An addition or subtraction command is given to the control input (A/S) from this control section 26. Initially, an addition order was given, and the number of coins (amount) inserted for each denomination was
ASR1 to ASR5 are each added and counted. The totaling circuit 21A is an addition/subtraction register corresponding to each amount.
The total input amount (or remaining amount) K is determined by adding up the contents of ASR1 to ASR5. The input amount K calculated by the summation circuit 21A is given to the amount display 22 and displayed to the outside, and is also sent to the sales availability determining section 23.
given to. The sales availability determining unit 23 determines the sales set price SPi of each product given from the price setting unit 24.
and the input amount K, taking into consideration the comparison result and other conditions (presence or absence of coins for change, etc.), determines the products that can be sold within the range of the input amount K, and determines the products that can be sold. Outputs sellable signal VE.
This sales enable signal VE is given to the sales circuit 25.

As is well known, the sales circuit 25 dispenses the product selected by the purchaser on the condition that the product is determined to be sellable. The sales circuit 25 outputs a product selection signal Si indicating the product selected by the purchaser, and also outputs a sales start signal VS when starting the product dispensing operation, and sends these signals to the coin changer device 11 for receipt and receipt. It is given to the money payout control section 26 and also given to other circuits (for example, the saleability judgment section 23) as necessary.

The collection and money dispensing control unit 26 mainly has the following functions:
Control for subtracting the set price SPi of the sold product from the input amount K (this is called collection control), change payout control, return control for the input amount, input refusal control, and other controls (for example, inventory control or limit on the number of input items) control, etc.). First, "receipt control" will be explained. This is executed when the sales start signal VS is given. When the control unit 26 is given the sales start signal VS, it enters the collection mode, and selects the product indicated by the product selection signal Si (i.e., the product to be paid out now) out of the sales set price SPi of each product given from the price setting unit 24. The set price of the popular item) is selected, and this value is subtracted from the input amount K stored in the amount counting section 21. Any method may be used for subtraction for revenue collection. For example, the value corresponding to the set price SPi of the sold product is always subtracted from the register ASR1 of the lowest denomination, and if the contents of this register ASR1 are less than the set price SPi, the register of the higher denomination is sequentially subtracted. ASR2
An appropriate method can be adopted, such as transferring the value equivalent to one coin from ... to the minimum amount register ASR1. For this purpose, the money collection and money dispensing control unit 26 includes each register.
The contents of ASR1 to ASR5 are given, and these contents (especially ASR1) are compared with the set price SPi of the selected product, and corresponding to the result, the addition/subtraction control input (A /S) is given an addition or subtraction command, and a count pulse is given to the count input (CI) as appropriate. Regardless of the subtraction method adopted for collection, when collection control is completed, the input amount K determined by the summation circuit 21A is the value obtained by subtracting the set price SPi of the sold product from the initial input amount, i.e. This value indicates the invested balance.

In the case of a single-item vending machine, when the above-mentioned cash collection control corresponding to one vending operation is completed, the control section 26 enters the change dispensing mode. In the case of a continuous sale type vending machine, when a predetermined continuous sale termination condition is met (for example, when it is determined that no product can be sold within the range of the balance K), the control unit 26 dispenses change. mode. In the change dispensing mode, the control unit 26 controls the coin dispensing mechanism 27 to dispense coins corresponding to the input amount (balance) K determined by the amount counting unit 21, and also controls the amount (number of coins) of the dispensed coins. Amount counting section 2
Control is performed to subtract from the contents of 1 (registers ASR1 to ASR5). Therefore, as the change coins are paid out, the input amount (balance) in the amount counter 21
K continues to decrease, and when K=0 finally, the change payout control ends.

When the return request switch 28 is turned on or when an automatic refund is to be made, the collection and money dispensing control section 26 enters the refund mode. The refund mode is the same as the change payout mode described above, in which money corresponding to the content K of the amount counter 21 is paid out and the paid amount (number of coins) is subtracted from the content of the amount counter 21. Similar to the above-mentioned money collection control, there are various methods of subtraction in the change payout and refund mode (namely, money payout mode), and any of them may be adopted.

The money collection and money dispensing control unit 26 outputs an insertion refusal signal CREM when the insertion of money should be rejected, and prohibits the insertion of money. Chain gear device 1
On the first side, the insertion rejection signal CREN controls the coin rejection electromagnetic device 29 and prohibits coin insertion. When the coin insertion is prohibited by the electromagnetic device 29, the inserted coin is detected by the amount-based coin detection unit SW500~
Before reaching SW10, the coins are guided to the return passage, and coins are not accepted or counted. As has been known, there are various cases in which money should be rejected. For example, accepting coins can be inconvenient, such as when controlling money withdrawal, when a power outage occurs, when a failure occurs, when the sales set price SPi is not set (zero), when controlling inventory, or when restricting the number of coins input by denomination. This is a case where there is a possibility that this may occur. In addition, even during the above-mentioned money collection control, if there is a possibility that accepting money will cause an inconvenience, the insertion refusal signal CREM may be outputted to reject the insertion of money. In the banknote identification device 10, the insertion detection unit 12 is connected to the banknote insertion slot 1.
This is for detecting that a banknote has been inserted into 0A. The banknote temporary storage and transfer control unit 13 controls the banknote transfer motor unit 14 according to various control signals.
Controls the normal rotation, reverse rotation, and stop of the banknotes, and controls the temporary storage and transfer of banknotes. The banknote control states by the control unit 13 include a "receiving state" in which the banknote is drawn from the insertion slot 10A to the temporary holding position P1, a "temporary holding state" in which the banknote is stopped at the temporary holding position P1, and a "temporary holding state" in which the banknote is stopped at the temporary holding position P1.
"Return state" where bills are sent out from temporary holding position P1 to 10A, bill storage from temporary holding position P1
4 “Payment status” to draw more banknotes into CBX
There is a condition. When a banknote is inserted into the insertion slot 10A, a banknote detection signal BD is emitted from the insertion detection section 12, and based on this, the control section 13 activates the motor section 14.
A forward rotation command is given to the banknote to draw the banknote to the temporary holding position P1. At the temporary holding position P1 or in the process of drawing the banknotes to the position, the authenticity determining unit 15 determines whether the inserted banknotes are genuine or false, and outputs a genuine note SKE if the banknote is a genuine banknote, and outputs a genuine note SKE if the banknote is a counterfeit banknote. Outputs ticket signal CC. Upon receiving the counterfeit bill CC, the control section 13 gives a reverse command to the motor section 14 to return the bill at the temporary holding position P1 to the insertion slot 10A.

Genuine bill signal SKE output from the authenticity determining unit 15
is applied to the circuit on the coin changer device 11 side via the wiring 16. Further, a collection signal CKE and a return signal RKE are sent from the circuit on the coin changer device 11 side via wiring 17 and 18 to the circuit on the banknote identification device 10 side (bill temporary storage and transfer control unit 1
3) is given. The control unit 13 receives the collection signal CKE.
When this is given, a control command for the "money collection state" is given to the motor unit 14. That is, the motor unit 14 is driven to rotate normally, and the banknotes at the temporary holding position P1 are stored in the banknote storage CBX. On the other hand, when the control section 13 receives the return signal RKE, it gives a control command for the "return state" to the motor section 14. That is, the motor unit 14 is driven in reverse to return the banknotes in the temporary holding position P1 toward the insertion slot 10A.

When the acceptance refusal unit 19 should reject the acceptance of banknotes, the acceptance refusal unit 19 closes the banknote insertion slot 10A or does not drive the motor unit 14 for “acceptance” even if the banknote detection signal BD is generated. Therefore, they refuse to accept banknotes. In this embodiment, an acceptance rejection signal NKE is given to the acceptance rejection section 19 from the coin changer device 11 side via the wiring 20, and when this acceptance rejection signal NKE is given, the above-mentioned acceptance rejection operation is performed. . Also, when the banknote is in the temporary storage position P1, the acceptance refusal section 19 operates to reject the banknote. Therefore,
The banknote identification device 10 is of a one-sheet holding type.
By the way, the acceptance rejection signal NKE is sent out through the same wiring 18 as the return signal RKE, and the control unit 13 sends it through the same wiring 18.
When the return signal RKE continues for a predetermined period of time or more, it may be determined that it is the acceptance refusal signal NKE, and the same acceptance refusal operation as described above may be performed. Therefore, in the illustrated embodiment, the number of wires connecting the bill identifying device 10 and the coin changing device 11 is four, but the minimum number of wires is a genuine bill signal SKE, a receipt signal CKE,
Three types of signal wiring can be used for the return signal RKE.

The coin changer device 11, in addition to various devices and circuits included in conventionally known changer devices exclusively for coins, accepts a genuine note signal SKE given from the banknote identification device 10, and calculates the amount of the input banknotes into the input total. Collection signal CKE, return signal based on the means for calculating the amount and appropriate conditions
It includes means for respectively sending an RKE and an acceptance rejection signal NKE. The amount counter unit 2 corresponds to the means for including the amount of the inserted banknotes into the total amount inserted.
1 and a banknote exchange control section 31. Each signal CKE,
The means for generating and transmitting RKE and NKE is included in the money collection and money dispensing control unit 26, and the control unit 2
Predetermined signals CKE, RKE,
NKE is generated. The control unit 26 outputs a banknote collection signal CKE1 when the banknotes temporarily reserved in the banknote identification device 10 are to be collected. this signal
CKE1 is applied to the wiring 17 via the OR circuit 39, and is supplied to the banknote identification device 10 as the collection signal CKE. The specific conditions for outputting the banknote collection signal CKE1 differ depending on which payment control method the control unit 26 employs. For example, when subtracting (resetting) the contents of the banknote addition/subtraction register ASR5 by 1 in the process of cash collection control, the banknote collection signal CKE1 is output at the same time, or when a sale is performed (that is, when the banknote collection mode is set). ) Outputs the banknote collection signal CKE1 regardless of the denomination of the currency to be collected, and also outputs the register ASR.
5 is subtracted by 1 (reset), or even if the contents of register ASR5 is 0, the banknote collection signal CKE1 is output at the time of collection (sales) just in case, or the change is output after collection. The cash receipt signal CKE1 is output on the condition that the contents of the register ASR5 are 0 at the time of payout (subtraction to collect 1,000 yen banknotes has been made at the time of collection). It is possible to set various specific conditions such as, but the point is that the banknote collection signal CKE1 is output when a 1,000 yen banknote is sold for redemption (at the time of collection or change payment). Further, the control unit 26 is controlled when the refund request switch 28 is operated to enter the refund mode, when the automatic refund mode is entered, or when the change payout mode is set (in short, when paying out money).
On the condition that "1" is stored in the register ASR5, or unconditionally, the return signal RKE is outputted and the banknote addition/subtraction register ASR5 is reset. Furthermore, if the conditions for generating the payment signal CKE1 and the return signal RKE are met at the same time,
The control unit 26 may output the collection signal CKE1 with priority, or the control unit 13 may use the signal CKE with priority. Further, the control unit 26 outputs a banknote acceptance refusal signal NKE under the same conditions as the coin insertion refusal signal CREM.

The banknote exchange control unit 31 either adds (memorizes) the inserted 1,000 yen banknote as it is in the 1,000 yen addition/subtraction register ASR5, or converts it to a lower denomination as necessary and stores it in the corresponding register ASR4...
Depending on the selection of the exchange selection switch 30, either addition or counting is performed. As described above, the banknote validating device 10 is of a one-sheet storage type, and in normal use, only one banknote can be inserted per purchase.
However, if it is possible to insert a plurality of bills per purchase by using this single bill holding type bill recognition device 10, it is convenient because the usage of the vending machine can be increased. A banknote exchange control section 31 is provided for this purpose.

When the currency exchange selection switch 30 is off, the bill exchange control unit 31 shown in FIG.
is always applied to the count input (CI) of the thousand yen addition/subtraction register ASR5, and when the switch 30 is on, a predetermined lower denomination (for example, 500 yen coin) is input in response to the genuine bill signal SKE corresponding to the first inserted bill. ) to generate the exchanged pulse and register the corresponding lower denomination.
ASR4 is given, and a genuine bill signal SKE corresponding to the second inserted bill is given to the thousand yen addition/subtraction register ASR5. That is, when the exchange selection switch 30 is off, no exchange of banknotes is performed, and the genuine note signal SKE
is exclusively counted and stored in the thousand yen addition/subtraction register ASR5. As will become clear later, in this case, only one bill can be inserted for each purchase. Furthermore, when the currency exchange selection switch 30 is on, the first inserted bill is of a predetermined lower denomination (e.g.
500 yen coin) and stored in the register ASR4 corresponding to that denomination, and the second inserted bill is stored in the 1,000 yen register ASR5 without being exchanged.
As will become clear later, in this case, two bills can be inserted for each purchase.
In addition, in this example, the addition/subtraction register ASR for 1,000 yen is used.
5 counts only one bill at most, so a simple 1-bit memory circuit may be used.

Genuine bill signal output from bill recognition device 10
The SKE is input to an exchange pulse generation circuit 32 and an AND circuit 33 in the banknote exchange control section 31. When the exchange pulse generating circuit 32 receives the genuine note signal SKE, it outputs pulses corresponding to the number of predetermined lower denomination coins corresponding to the amount of one banknote (this is referred to as an exchange pulse EX). When exchanging 1,000 yen banknotes into 500 yen coins and counting them, two exchange pulses EX are generated in response to one genuine note signal SKE. The exchange pulse EX is input to the AND circuit 34. Further, when the exchange pulse generation circuit 32 finishes generating the exchange pulse EX, it outputs an exchange end pulse F and supplies it to the storage circuit 35. Based on this exchange end pulse F, "1" is stored in the storage circuit 35. When the selling operation is completed (when the total input amount K becomes 0), a reset pulse R is generated, and this reset pulse R is applied to the reset input of the memory circuit 35 via the OR circuit 41, and the reset pulse R is applied to the reset input of the memory circuit 35 through the OR circuit 41. Reset. Therefore, during standby (before the first bill is inserted), the output of the memory circuit 35 is "0". The output of the memory circuit 35 is applied to the AND circuit 33 via the OR circuit 36 and also to the inverter 3.
7 and is inverted and applied to the AND circuit 34. Further, the output of the memory circuit 35 is given to a signal generation circuit 38. The signal generating circuit 38 outputs "1" for a certain period of time after the signal applied from the memory circuit 35 rises to "1". The output "1" of the signal generation circuit 38 is applied to the wiring 17 via the OR circuit 39, and is applied to the banknote identification device 10 as the receipt signal CKE. In addition, the exchange selection switch 30
always gives a signal "1" to the OR circuit 36 when it is off, and gives a signal "0" to the OR circuit 36 when it is on. The output of the AND circuit 33 is given to the count input (CI) of the 1,000 yen addition/subtraction register ASF5, and the output of the AND circuit 34 is sent to the OR circuit 40 for 500 yen.
Count input (CI) of addition/subtraction register ASR4 for yen
given to. 500 for other inputs of OR circuit 40
The output of the yen coin detection unit SW500 is added. Further, the output of the switch 30 is applied to the reset input of the memory circuit 35 via an OR circuit 41, and the memory circuit 35 is always reset when the switch 30 is off.

When the exchange selection switch 30 is off, the AND circuit 3 is output from the switch 30 via the OR circuit 36.
3 is always given "1" to one input. On the other hand,
One input of the AND circuit 34 receives a signal “0” obtained by inverting the output “1” of the OR circuit 36 by the inverter 37.
is always given. When a banknote is inserted into the banknote identification device 10, the banknote is pulled into the temporary holding position P1 under the control of the control unit 13 as described above. When the authenticity determining section 15 determines that the inserted bill is genuine, a genuine bill signal SKE is supplied to the coin changer device 11 via the wiring 16. This genuine note signal
SKE passes through the AND circuit 33 and is input to the thousand yen addition/subtraction register ASR5.
The insertion of one genuine bill is memorized. Also, genuine note signal
The exchange pulse EX is generated from the exchange pulse generation circuit 32 in response to SKE, but is blocked by the AND circuit 34. Further, since the off output "1" of the switch 30 is applied to the reset input of the memory circuit 35 via the OR circuit 41, and the output of the circuit 35 is always "0", the output of the signal generation circuit 38 is also applied. It is always “0”. Therefore, the collection signal CKE
is not generated immediately, and the inserted banknote remains at the temporary holding position P1 within the banknote identification device 10. Therefore, additional insertion of banknotes is prevented, and only one banknote can be inserted. Eventually, when the selling operation is executed and the control unit 26 enters the payment mode, the banknote collection signal CKE1 is output and the banknote register is activated.
ASR5 is reset (subtracted by 1). this signal
Based on CKE1, from OR circuit 39 to wiring 17
A collection signal CKE is given to the banknote recognition device 10 via the banknote recognition device 10. The control unit 13 of the device 10 receives a payment signal.
In response to CKE, money collection control is executed and the banknotes in the temporary holding position P1 are stored in the banknote storage CBX. When a return signal RKE is generated from the control unit 26 when a refund request is made or when change is paid out, the control unit 13 of the banknote identification device 10 executes banknote return control, and at that time, the banknote is placed in the temporary holding position P1. If so, the banknotes will be returned.

When the exchange selection switch 30 is on, "0" is applied to the OR circuits 36 and 41. Therefore, AND circuits 33 and 34 are controlled by the output of storage circuit 35 which is added to the other input of OR circuit 36. Further, the reset of the memory circuit 35 is controlled by a reset pulse R applied to the other input of the OR circuit 41. During standby, the output of the memory circuit 35 is "0", the AND circuit 33 is inoperable, and the AND circuit 34 is inoperable. When the first bill is inserted, as mentioned above,
This banknote is placed at the temporary holding position P1 of the banknote identification device 10.
At the same time, if it is a genuine currency, a genuine bill signal is issued.
SKE is output. An exchange pulse EX is generated from the exchange pulse generation circuit 32 in response to the genuine note signal SKE, and is passed through an AND circuit 34 and an OR circuit 40.
This is given to the 500 yen coin addition/subtraction register ASR4. On the other hand, the genuine note signal SKE is blocked by the AND circuit 33,
It is not given to the 1000 yen coin addition/subtraction register ASR5. Therefore, the first thousand yen bill inserted is 500 yen.
Exchanged to yen, 2 in 500 yen register ASR4
The number of inserted sheets is counted and stored.

When the generation of the exchange pulse EX ends, an exchange end pulse F is output from the circuit 32, and the exchange end pulse F is output from the memory circuit 35.
“1” is stored in . In response to the rise of the output "1" of the memory circuit 35, the signal generating circuit 38 outputs a signal "1" with a constant time width, and in response, the OR circuit 39 outputs the collection signal CKE. In this way, in response to the receipt signal CKE that is generated based on the completion of the exchange of the first inserted bill, the first inserted bill that has been temporarily held is transferred to the bill storage.
Stored in CBX. This makes it possible to add one more bill. At this time, since the output of the memory circuit 35 is "1", the AND circuit 33 is inoperable and the AND circuit 34 is inoperable, contrary to the initial state. When the second bill is inserted, it is held at the temporary holding position P1 and the genuine note signal SKE is generated in the same manner as described above. This second genuine note signal SKE passes through the AND circuit 33 and is added to the thousand yen coin register ASR5, and the value of one thousand yen coin is stored in the register ASR5. On the other hand,
Since the exchange pulse EX is blocked by the AND circuit 34, the 500 yen coin register ASR4 does not increase in number. Furthermore, since the memory circuit 35 remains set to "1" when the exchange of the first inserted bill is completed, the signal generating circuit 35 remains set to "1" in response to the second inserted bill.
"1" is never output from 8. Therefore,
The second inserted bill remains at the temporary holding position P1 for a while.

Therefore, when two bills are inserted, the memory content of the thousand yen coin register ASR5 becomes "1", the memory content of the 500 yen coin register ASR4 becomes "2", and one bill is stored in the bill recognition device 10. It is temporarily on hold. Of course, if a 500 yen coin is inserted separately,
Since the register ASR4 is incremented by the output of the detection unit SW500, the contents of the register ASR4 become the sum of the actual number of 500 yen coins inserted and the number of 1,000 yen coins exchanged (2 coins). Addition/subtraction register for thousand yen coins
The contents of ASR5 indicate the number of banknotes that can be returned (temporarily held).

The receipt signal CKE1 (CKE) and the return signal RKE are generated at the time of money collection and money payout in the same way as described above, and based on this, the second inserted banknote that was temporarily held is stored in the banknote storage CBX, or Return the bill to the bill insertion slot 10A. When the selling operation is completed and the total input amount K becomes 0, a reset pulse R is activated.
is generated, and the memory circuit 35 is reset.

If the refund request switch 28 is operated after the first bill is inserted, the 500 yen coin register
Based on the contents of ASR4, two 500 yen coins will be refunded. If the refund request switch 28 is operated after the second bill has been inserted, the 1,000 yen coin register
Based on the contents of ASR5 and 500 yen coin register ASR4, one 1000 yen banknote and two 500 yen coins will be refunded. As is clear from the above, there is no particular problem if you collect the exchanged amount, but if you have to refund the money without collecting it, there is a shortage of stored coins for change of the lower denomination that was exchanged. If you do so, you may not be able to receive a refund. In order to deal with such inconveniences, it is possible to consider the shortage of coins stored for change as a condition for generating the exchange pulse in the banknote exchange control unit 31, or to consider the shortage of stored coins for change in the coin dispensing control in the money collection and coin dispensing control unit 26. For denominations in which coins are in short supply, register
What is necessary is to take measures such as not dispensing the coins according to the contents of ASR1 to ASR4, but transferring them to a different denomination and dispensing them. The coin changer device 11 is provided with a coin storage device for change for each denomination in association with the coin dispensing mechanism 27, and is further provided with means for detecting whether or not there is a shortage of stored coins in each storage device.

Using the detection result of the storage change coin shortage detecting means, the control section 31 or the control section 26 may perform special processing when change coins are insufficient as described above. For example, the banknote exchange control unit 31
If this is done, the exchange control is performed as shown in Figure 1 on the condition that there is no shortage of 500 yen coins, but if there is a shortage of 500 yen coins, the exchange pulse generation circuit 32 controls the exchange of 500 yen coins. Instead of the pulse (2 pulses), a 100 yen exchange pulse (10 pulses) may be output, and this 100 yen exchange pulse may be input to the addition/subtraction register ASR3 for 100 yen coins. Furthermore, if there is a shortage of change for 100 yen coins, for example, the acceptance rejection signal NKE is generated to reject the banknotes, or the control unit 31 is completely prohibited from controlling the exchange of input banknotes (in other words, the switch 30 is You can take measures such as setting it to the same state as when it was off). In addition, when performing this with the money collection and money dispensing control unit 26, if there is insufficient change for 500 yen coins, the register ASR4
Transfer the number of exchanged coins (2 coins) stored in the memory to register ASR3 for 100 yen coins (enter "10" in ASR3).
).

The banknote exchange control unit 31 shown in FIG. 1 is designed to unconditionally exchange the first inserted banknote.
The present invention is not limited to these, and the exchange storage may be performed on the condition that the next banknote is inserted. For that purpose, the banknote exchange control section 31 in FIG.
What is necessary is just to change it as shown in 1A.

In FIG. 2, only the banknote exchange control section 31A and its related circuits are shown, but the other components can use the same configuration as in FIG. 1. The same symbols as in FIG. 1 indicate the same devices. The genuine note signal SKE output from the banknote identification device 10 (FIG. 1) is applied to the count input (CI) of the thousand yen coin addition/subtraction register ASR5. The banknote exchange control unit 31A includes a banknote identification device 10.
A banknote insertion detection signal BD output from the insertion detection section 12 is given. This insertion detection signal BD is delayed by a predetermined time in a delay circuit 60 and then sent to a storage circuit 61.
given to. This insertion detection signal BD is delayed for a predetermined time by a delay circuit 60 and then applied to a storage circuit 61. The delay time of the delay circuit 60 is set to be somewhat longer than the time during which the insertion detection signal BD becomes "1" in response to insertion of a banknote. The insertion detection signal BD, the output signal of the storage circuit 61, and the output signal of the exchange selection switch 30 are input to the AND circuit 62. In FIG. 2, it is assumed that the exchange selection switch 30 outputs "0" when it is off. AND circuit 62 outputs an insertion detection signal when three input conditions are met.
Outputs “1” for a short time at the BD timing. The output of this AND circuit 62 is
3 and the exchange pulse generation circuit 64. Similar to the signal generating circuit 38 in FIG. 1, the signal generating circuit 63 outputs "1" for a certain period of time when the signal "1" is input, and the output signal "1"
is given to the banknote identification device 10 via the OR circuit 39 as the collection signal CKE.

Like the memory circuit 35 in FIG. 1, the memory circuit 61 is reset by a reset pulse R at the end of the sales operation (standby). Therefore, when the first bill is inserted, the output of the memory circuit 61 is "0", and when the bill insertion detection signal BD corresponding to the first bill inserted is "1", the output of the AND circuit 62 is "0". The condition is not met. After the first insertion detection signal BD falls to "0", the output of the delay circuit 60 becomes "1" and "1" is stored in the storage circuit 61.
Therefore, the AND circuit 62 receives the first insertion detection signal.
BD is blocked, but "1" is output in response to the second and subsequent bill insertion detection signals BD.

A signal indicating the contents of the thousand yen coin addition/subtraction register ASR5 is given to the enable input (EN) of the exchange pulse generation circuit 64, and this register
This exchange pulse generation circuit 6 is provided on the condition that the ASR 5 stores one (or more than one) banknote.
4 becomes operational. The exchange pulse generation circuit 64 is activated by the signal applied to the enable input (EN).
is in the operable state, AND circuit 6
2, the circuit 64 generates an exchange pulse EX corresponding to a coin unit of a predetermined denomination.
Output. Similarly to the above, when exchanging a 1,000 yen bill into a 500 yen coin, an exchange pulse EX consisting of two pulses per bill is output. When the circuit 64 finishes outputting the exchange pulse EX, it outputs an exchange end pulse F.
Output. This exchange end pulse F is applied to the reset input (R) of the thousand yen coin addition/subtraction register ASR5, and resets the memory of bill insertion in the register ASR5. In addition, the exchange pulse EX is connected to an addition/subtraction register for 500 yen coins via an OR circuit 40.
It is applied to the count input (CI) of ASR4, and the contents of the register ASR4 are incremented by two.

When the exchange selection switch 30 is off as shown, "0" is always input to the AND circuit 62, and the AND circuit 62 is always inoperable. Therefore,
The signal generation circuit 63 and exchange pulse generation circuit 64 do not operate at all, and exchange control is not executed. In this case, the first banknote inserted is the banknote identification device 10.
It continues to be held at the temporary holding position P1 (Fig. 1) until its disposition is finalized. When it is confirmed that the temporarily reserved banknotes will be collected or refunded as a result of the sales operation (or based on a refund request), a collection signal CKE (CKE1) is sent from the collection and money dispensing control unit 26 (FIG. 1). Or return signal
RKE is output and the first bill inserted is finally collected or refunded. Thus, when switch 30 is off, only one bill can be inserted per sale, as is conventional.

When the exchange switch 30 is turned on, "1" is always input from the switch 30 to the AND circuit 62. First, when the first bill is inserted, the bill insertion detection signal BD becomes "1", but the memory circuit 61
is reset to “0”, so AND circuit 6
Condition 2 does not hold. When "1" is stored in the memory circuit 61 by the delayed signal BD, the signal BD has already fallen to "0", so the condition of the AND circuit 62 still does not hold. On the other hand, when it is determined that the first inserted bill is a genuine bill, the genuine bill signal SKE is given to the thousand yen coin addition/subtraction register ASR5, and the register ASR5 is set to "1".
is memorized. The first inserted banknote is temporarily held at the initial temporary holding position P1 (FIG. 1).

When the second banknote is inserted into the insertion slot 10A (FIG. 1), an insertion detection signal BD is output from the insertion detection section 12 (FIG. 1). Banknote exchange control unit 31A
Since "1" has already been stored in the storage circuit 61, the condition of the AND circuit 62 is satisfied when the second insertion detection signal BD is applied, and the signal generation circuit 63 and exchange pulse generation circuit 64 A signal “1” is input. Based on this, the signal generation circuit 63
A signal “1” is output for a certain period of time from
0 (Figure 1). Furthermore, since "1" indicating the first inserted bill is stored in the thousand yen coin addition/subtraction register ASR5, the exchange pulse generation circuit 64 is in an operable state, and the signal "1" from the AND circuit 62 is stored. Currency exchange based on Pulse
It generates EX and outputs exchange end pulse F. This exchange pulse EX increases the contents of the 500 yen coin addition/subtraction register ASR4 by two 500 yen coins. Furthermore, the memory of the first inserted bill in the thousand yen coin register ASR5 is reset by the exchange end pulse F. In this way, based on the insertion of the second bill, the first inserted bill is simply exchanged and stored as a predetermined lower denomination coin (500 yen coin). On the other hand, the bill validating device 10 (FIG. 1) accepts the first inserted bill that has been placed in the temporary holding position P1 into the storage CBX based on the receipt signal CKE. This is because the first inserted bill was exchanged into a 500 yen coin, so there was no longer any reason to keep it on hold. When the temporary holding position P1 becomes empty, the second inserted banknote is drawn into the temporary holding position P1 from the insertion slot 10A. Then, when the genuine note signal SKE corresponding to the second inserted bill is generated, one bill is again stored in the thousand yen coin addition/subtraction register ASR5.

When the third bill is inserted, the condition of the AND circuit 62 is satisfied, and the memory for the second inserted bill in the register ASR5 is stored in the same way as when the second bill was inserted. The exchange is stored in register ASR4, and the second inserted bill is temporarily held at position P.
From 1 onwards, the money will be collected in the storage warehouse CBX. Then, the third inserted banknote is held at the temporary holding position P1, and "1" is stored in the banknote register ASR5 based on the genuine note signal SKE of this third banknote.
In this way, each time the next bill is inserted, the previously inserted bill is exchanged and stored in units of coins of lower denominations, and the money is collected, making it possible to continuously insert any number of bills. can. That is, only the last one of the continuously inserted bills remains in the temporary holding position P1 and is stored in units of that bill, while the others are exchanged and stored in units of predetermined lower denomination coins and stored internally (in the storage CBX). ) will be collected. Of course,
The acceptance refusal signal NKE may be generated from the collection and money dispensing control unit 26 after a suitable number of banknotes have been continuously inserted to prohibit further banknote insertion and limit the maximum number of banknotes to be inserted. For example, if two bills are inserted in succession, the 1,000 yen register ASR
When the content of 5 is "1" and the content of 500 yen coin register ASR4 is "2" or more, an acceptance refusal signal is sent.
Generate NKE and increase the maximum number of consecutively inserted banknotes by 2
It is possible to limit the number of copies.

In the embodiment shown in FIG. 2, if the refund request switch 28 (FIG. 1) is operated after the first banknote is inserted, the return signal RKE is issued and the banknote in the temporary holding position P1 is returned. At the same time, "1" is subtracted (reset) from the content "1" of the thousand yen coin register ASR5. Therefore, it is possible to return the inserted banknotes as they are. Additionally, if the refund request switch 28 is operated after two or more bills have been inserted, the one bill in the temporary holding position P1 will be refunded based on the return signal RKE, and the contents of the 500 yen coin register ASR4 will be refunded. Based on this, the remaining banknotes will be converted into 500 yen coins and refunded. In addition, if two bills are inserted and the sale is less than the amount equivalent to one bill, the collection and money dispensing control unit 26 (FIG. 1)
It is also possible to collect the sales price from the contents of the 500 yen coin register ASR4 and control the refund using one temporarily reserved bill as change.

In the embodiment shown in Fig. 2, as in the embodiment shown in Fig. 1, if the exchanged amount must be refunded,
If there is a shortage of stored change coins of the specified lower denominations that have been exchanged, there is a risk that refunds will not be possible, so as mentioned above, measures should be taken in consideration of the shortage of change stored coins to avoid any inconvenience. It is preferable to take appropriate measures.

In addition, in the examples shown in Figures 1 and 2, 1,000 yen banknotes are used.
Although the currency is exchanged into 500 yen coins and counted and memorized, it is also possible to exchange the money into 100 yen coins (or other denominations) and store the counts. To do this, the number of exchange pulses EX generated from the exchange pulse generation circuits 32 and 64 is set to 10 pulses, and the exchange pulse consisting of these 10 pulses and the output pulse of the 100 yen coin detection unit SW100 are ORed to the 100 yen coin addition/subtraction register ASR3. All you have to do is enter it.

<Effects of the Invention> As explained above, according to the present invention, input banknotes exceeding the number that can be temporarily held in the banknote recognition device are exchanged and stored in units of coins of predetermined lower denominations, so that the number of banknotes that can be temporarily held is reduced. It becomes possible to continuously insert a larger number of banknotes. Therefore, when making a large purchase, inserting multiple bills saves the buyer the effort of inserting multiple bills, and reduces the desire to purchase, which tends to occur when a large number of coins have to be inserted. It will no longer occur. Furthermore, as the amount of money inserted increases due to continuous insertion of banknotes, it is expected that usage of the vending machine and sales will increase. In addition, by exchanging banknotes for coin denominations with relatively low circulation (for example, the 500 yen coin that is scheduled to be newly issued) or coin denominations that are used relatively infrequently as change, the circulation of these coins will be promoted. It is expected that this will lead to an increase in the operating rate of vending machines.
