DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cash register such as a point-of-sale (POS) terminal connected to an automatic change machine.

[0002]

2. Description of the Related Art A master POS terminal, which is an upper model, is connected to a plurality of satellite POS terminals for registering product sales data via a transmission line, and the satellite POS terminals are centrally managed by the master POS terminal. Master satellite type POS systems are widely used in mass retailers such as supermarkets.

Heretofore, a merchandise sales registration operation using such a satellite POS terminal has been performed as follows. That is, a clerk operating the satellite POS terminal,
When a so-called cashier uses a barcode scanner or an input device such as a keyboard to input a code of a product purchased by a customer, product data (product name, unit price, etc.) corresponding to the product code is read from the product data file. Then, based on the product data, the product sales data such as the number of sales and the sales amount are obtained and registered for sales, and the sales amount is added to the contents of the total amount memory.
In addition, the detailed data (product name, unit price,
The number of sales, the sales amount, etc.) are displayed on the display and printed on a receipt paper or the like by a printer. The contents of the total amount memory are cleared in response to the first product registration of one customer.

[0004] When the sales registration of all the products purchased by one customer is completed, the total amount memory stores the total amount of all the products purchased by that customer. Also, since this total amount is displayed on the display, the customer pays for the total amount.

[0005] Here, when the customer pays for the cash, the cashier operates the numeric key on the keyboard to enter the deposit amount from the customer, and then inputs the closing key. To declare that one transaction has been registered. Then, a change operation for subtracting the total amount from the deposit amount is performed, the calculated change is displayed on the display, and a receipt is issued. In addition, since the drawer for storing cash by denomination is automatically opened, the cashier stores coins received from customers in the drawer by denomination, and arranges coins equivalent to change from the drawer on receipt. Hand over to customer.

If the deposit amount is less than the total amount, the operation input of the closing key results in an error, and the number of the deposit amount and the operation of the closing key are redone.

[0007] Here, the cashier completes the accounting business including the transfer of money, and ends the merchandise sales registration business with the customer.

Meanwhile, there is an automatic change machine as an apparatus for improving the work efficiency of the accounting business in the merchandise sales registration business. This automatic change machine, when receiving change data from a connected POS terminal, automatically discharges the money corresponding to the change. The money received from the customer is automatically classified into denominations and stored. Can be recycled as change.

[0009] By using such an automatic change machine, there is no need to arrange and pay the money corresponding to the change to the customer, so that a part of the cashier's burden in the accounting operation is reduced.

Incidentally, such an automatic change machine stores and manages the number of stored coins for each denomination, and includes a display for displaying the data of the number of coins and a key for instructing the display. The number of stored coins can be confirmed by denomination.

Therefore, conventionally, for example, an accountant such as a store manager visits a satellite POS terminal installation location in a timely manner to check the number of coins stored in the automatic change machine, and replenishes money if it is insufficient. Was like that.

[0012]

However, conventionally,
In order to check the number of coins stored in the automatic change machine connected to each satellite POS terminal, it is necessary to repeat the same key operation around the installation location of each satellite POS terminal, which is troublesome. Time-consuming and complicated work has been required.

Accordingly, the present invention provides a method for collectively checking the number of stored coins of each denomination of an automatic change machine connected to each cash register machine by a higher-level model connected to each cash register machine via a transmission line. It is an object of the present invention to provide a cash register with an automatic changer which can simplify the operation of checking the number of stored coins in each automatic changer.

[0014]

According to the present invention, there is provided an automatic changer which is connected to an upper model via a transmission line and is capable of storing and managing the number of stored coins by denomination, and inputting an operation of a closing key. When the deposit amount corresponding to the total amount of one transaction is input, the change is calculated from the deposit amount and the total amount, the change data is transmitted to the automatic change machine, and the money equivalent to the change is discharged from the automatic change machine. In a cash register with an automatic changer, first check command transmitting means for transmitting a command for confirming the number of stored coins to the automatic changer every time change data is transmitted to the automatic changer; Each time the number data of the denominated storage coins transmitted from the automatic change machine in response to the transmission of the number confirmation command by the command transmission means is received, the latest received data is stored. Means, a command validity determining means for determining whether or not a command can be transmitted to the automatic changer when an inspection command of the automatic changer is received from the upper model via a transmission line, and a command validity determining means. When it is determined that the command can be transmitted, a second confirmation command transmitting means for transmitting a number confirmation command to the automatic change machine, and a response to the transmission of the number confirmation command by the second confirmation command transmitting means. Receiving the number data of the denominated stored coins transmitted from the automatic changer and transmitting the received data to a higher-level model via a transmission line, a first denominated stored coins number transmitting means, and a command availability determining means When the command transmission is determined to be impossible by the command and the transmission of the number confirmation command by the second confirmation command transmission means is performed automatically. When it does not receive a response data from the machine, in which a second money storage money number transmitting means for transmitting the stored data by money storage money number storing means to the upper model via the transmission line.

[0015]

In the cash register with an automatic changer of the present invention having the above-described structure, when the deposit amount corresponding to the total amount of one transaction is inputted by operating the closing key, the deposit amount and the total amount are calculated. The change is calculated and the change data is transmitted to the automatic change machine. As a result, money equivalent to the change is discharged from the automatic change machine.

At this time, a command for confirming the number of stored coins is transmitted to the automatic change machine. As a result, the automatic change machine transmits the data of the number of coins stored by denomination after the money corresponding to the change is discharged, and receives and stores the data.

On the other hand, when an inspection command of the automatic change machine is received from the upper model via the transmission line, it is determined whether or not a command can be transmitted to the automatic change machine. Then, when a command can be transmitted, a number confirmation command is transmitted to the automatic change machine. As a result, the data of the number of coins stored by denomination is transmitted from the automatic change machine, and the data is received and transmitted to the upper model via the transmission line.

On the other hand, when the command transmission is not possible or when the number data of the denomination storage money is not received from the automatic change machine despite the transmission of the number confirmation command, the stored denomination is stored. The data of the number of stored coins is transmitted to the upper model via the transmission line.

Therefore, in the upper model, by transmitting the check command of the automatic change machine to each cash register with automatic change machine connected via the transmission line, the automatic change connected to each cash register can be performed. Since the data on the number of stored coins by denomination in the machine can be collected, for example, by outputting the collected data as a report, the number of stored coins by denomination of each automatic change machine can be collectively checked.

[0020]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall view of a master satellite type POS system using a cash register with an automatic change machine according to the present invention for a satellite POS terminal.

A file processor 4 that manages various files such as sales data files that accumulate and store data by classifying the data by product, department, time zone, etc., is connected via a transmission line 5 in a closed loop.

FIG. 2 is a block diagram showing a main configuration of the S-POS terminal 2-1. Note that other S-POS terminals 2
-2-2 to 2-n have the same configuration as the S-POS terminal 2-1, and thus description thereof will be omitted.

The S-POS terminal 2-1 has a CPU (Central Processing Unit) 11 as a control unit main body, and a ROM as a main storage unit controlled by the CPU 11.
(Read only memory) 12 and RAM 13 (random access memory).

Fixed data such as program data for operating the CPU 11 is stored in the ROM 12 in advance. The RAM 13 has various memory areas such as a sales registration memory for registering sales of merchandise sales data and a total amount memory for storing a total amount of transactions.

The S-POS terminal 2-1 includes a clock circuit 14 for measuring the date and time, and a communication interface 1 for controlling data transmission performed through the transmission line 5.
5. A changer interface 16 for controlling data transmission with the automatic changer 1-1, a printer controller 18 for controlling data printing by a printer 17, a display controller 20 for controlling data display on a display 19, and a keyboard 21. The I / O port 25 for sending an opening command signal to a drawer opening device 24 for automatically opening the keyboard controller 22 for taking in the key input signal of the above and the drawer 23 are mounted.

The CPU 11, the ROM 12,
RAM 13, clock circuit 14, communication interface 15,
Change machine interface 16, printer controller 1
8. The display controller 20, the keyboard controller 22, and the I / O port 25 are mutually connected by a bus line 26 such as a data bus and an address bus.

The printer 17 prints the name, price, total transaction amount, and the like of products registered for sale on receipt paper and journal paper. The receipt paper printed by the printer 17 is discharged from a receipt issuing port. It is cut and a receipt is issued. The journal paper is wound up inside.

The display unit 19 displays the name, price, total transaction amount and the like of the products registered for sale, and is provided with two types of display units, one for cashiers and one for customers.

The keyboard 21 is provided with the number of products for sale,
A numeric key for entering numerical data such as prices, a code key for entering the code of a product for sale, a total key for outputting the total transaction amount, and a closing key for inputting a deposit amount for the total transaction amount. This is a keyboard dedicated to a POS terminal on which various keys such as keys are provided.

The drawer 23 stores spare coins in addition to various bills.

FIG. 3 is a functional block diagram of the automatic change machine 1-1 connected to the S-POS terminal 1-1. Since the automatic change machines 1-2 to 1-n connected to the other S-POS terminals 1-2 to 1-n have the same configuration as the automatic change machine 1-1, the description here will be omitted. Omitted.

The automatic change machine 1-1 includes a change machine control section 31 composed of a microcomputer or the like and a POS interface 32 and a key / display section 33 for controlling data transmission with the S-POS terminal 2-1. A key / display control circuit 34 to be controlled is connected.

Also, a coin sorting circuit 36 for sorting coins inserted from the coin insertion slot 35 into denominations, a coin storage section 37 for storing coins sorted by denomination by the coin sorting circuit 36, and a change. The coins stored in the coin storage unit 37 in response to a command from the machine control unit 31 are transferred to a coin outlet 38.
And a coin ejection command circuit 39 for ejecting a required number of coins from the coin storage unit 37, and a stored coin number counting unit 40 for storing and managing the number of coins stored in the coin storage unit 37 by denomination.

This automatic change machine 1-1 is already on the market, and when change data is given from the S-POS terminal 2-1, the change machine control unit 31 minimizes the number of coins equivalent to change. The combination is determined, and a command is issued to the coin ejection command circuit 39. As a result, coins equivalent to change are automatically discharged from the coin discharge port 38. For example, change 15
If it is 6 yen, 100 yen coin, 50 yen coin, 5 yen coin, and 1 yen coin are discharged one by one. Further, when coins to be received and replenished coins are collectively inserted from the coin insertion slot 35, the inserted coins are sorted by denomination and stored in the coin storage unit 37.

Each time a coin is ejected from the coin outlet 38, the stored coin number counting section 40 counts down the counted value of the number of coins by type of the ejected coin by the number of ejected coins. Also, every time a coin is inserted from the coin insertion slot, the denomination number count value of the inserted coin is counted up by the inserted number.

When the number check mode is selected by operating a specific key on the key / display unit 33, the change machine control unit 31 reads the count value of the denomination type in the stored coin number counting unit 40 and reads the content. It is displayed in the display area of the key / display unit 33.

FIG. 5 is a block diagram showing the main configuration of the M-POS terminal 3. As shown in FIG. As is apparent from comparison with FIG. 2, the M-POS terminal 3 and each of the S-POS terminals 2-1 to 2-n have substantially the same configuration.

That is, the M-POS terminal 3 is
1. ROM 52, RAM 53, clock circuit 54, communication interface 55, changer interface 56, printer controller 57, display controller 58, keyboard controller 59, I / O port 60, and the like. Interconnected.

However, in this embodiment, the M-POS terminal 3 is not connected to an automatic change machine. The printer controller 57 and the display controller 58 are connected to the same printer 62 and display 63 as the S-POS terminals 2-1 to 2-n, respectively. A keyboard 64 dedicated to the POS terminal is normally connected to the keyboard controller 59, but a JIS standard compliant keyboard in which, for example, character keys, numeric keys, cursor keys, and the like are arranged can be connected for setting work and the like. .

A drawer opening device 66 for automatically opening the drawer 65 is connected to the I / O port 60, and a mode switch 67 is connected to the I / O port 60.
7 is input to the I / O port 60 and the CPU 5
1 is read.

The mode switch 67 is a switch for selectively switching various operation modes such as a registration operation, an inspection operation, a settlement operation, and a setting operation, and is operated by, for example, a key.

By the way, the registration work is defined as each S-POS terminal 2
In the same manner as -1 to 2-n, the operation of registering the sales data of the merchandise obtained by the operation input of the keyboard 64 in the sales registration memory of the RAM 53 and the inspection operation are the S-POS terminals 2-1.
The task of selectively collecting data from the 2-n RAM 13 and printing or displaying the data, and the settlement task are each S-POS.
The sales registration data stored in the sales registration memories of the terminals 2-1 to 2-n are collected, totaled by the sales data file of the file processor 4, and each of the S-POS terminals 2-1 to 2-2.
The task of clearing the contents of the sales registration memory of -n to zero and the setting task are tasks of setting necessary data in the RAM 13 of each of the POS terminals 2-1 to 2-n in advance.

In this embodiment, however, each S-POS
In the RAM 13 of each of the terminals 2-1 to 2-n, as shown in FIG. 4, a change buffer 70 for storing data of the number of warnings, the number of stored coins, the total amount, and the warning flag for each coin type is formed.

Incidentally, the number of stored coins is the number of coins of the corresponding denomination stored in the automatic change machine connected to the S-POS terminal 2-1 to 2-n. The warning number is an appropriate number to determine that the number of coins of the corresponding denomination is insufficient, and the warning flag is the number of coins of the corresponding denomination. This flag is set to "1" when the number of stored images becomes equal to or less than the warning number.

The denomination data (500, 100, 5)
0, 10, 5 and 1) and the corresponding warning number data are previously set in common for each S-POS terminal by setting work in the M-POS terminal 3.

In such a configuration, the CPU 11 of each of the S-POS terminals 2-1 to 2-n is programmed so as to process the merchandise sales registration business in accordance with the flowchart of FIG.

That is, first, as ST1, the registration of the product purchased by the customer is processed. More specifically, since the cashier uses the keyboard 21 to enter the code of the product purchased by the customer, the product data (product name, unit price, etc.) corresponding to the product code is read from the product data file provided in the file processor 4. The product is read out, and based on the product data, the product sales data such as the number of sales and the sales price are obtained to obtain the RA.
The registration processing is performed on the sales registration file of M13, and the sales amount is added to the contents of the total amount memory of the RAM 13. Further, detailed data (article name, unit price, number of sales, sales amount, etc.) of the merchandise registered for sale is displayed on the display 19, and is printed by the printer 17 on receipt paper and journal paper. The contents of the total amount memory are cleared in response to the first product registration of one customer.

Next, in ST2, it is determined whether or not the closing key of the keyboard 21 has been operated. If the closing key is not operated, the process returns to ST1. When the closing key is operated and input, the change is calculated and displayed on the display 19 as ST3.

More specifically, when the cashier finishes registering all the products purchased by one customer, the total price of all the products purchased by that customer stored in the total price memory is displayed on the display unit 19. The customer will pay for the sum. Here, when the customer pays for the cash, the cashier operates the numeric key on the keyboard 21 to enter the deposit amount from the customer, and then operates the closing key to enter one transaction. Since the end of registration is declared, a change operation for subtracting the total amount from the deposit amount is performed, and the calculated change amount is displayed on the display 19.

Next, in ST4, when the data such as the total amount, the deposit amount, and the change is printed on the receipt paper and the journal paper by the printer 17, the receipt paper is cut and a receipt is issued. Also, I / O port 25
A drawer opening signal is sent to the drawer opening device 24 through the, and the drawer 23 is opened.

Next, as ST5, it is determined whether or not the change calculated in ST3 has a fractional amount of less than 1,000 yen. If there is no fraction of change of less than 0 yen or 1000 yen, the change is "NO" because there is no change of coins, and the current registration operation is terminated.

If the change has a fractional amount of less than 1,000 yen in ST5, it means "YES" because there is a coin change.
In step ST6, the change data corresponding to the fractional amount less than 1,000 yen is sent to the automatic change machines 1-1 to 1-1 via the change machine interface 16.
Send to -n.

As a result, coins corresponding to the change data are discharged from the automatic change machines 1-1 to 1-n, and when the discharge is completed, a discharge completion response is returned to the POS terminals 2-1 to 2-n. If the CPU 11 receives the ejection completion response within a predetermined time after transmitting the change data in ST7, the CPU 11 issues a command to confirm the number of stored coins through the changer interface 16 to the automatic change machines 1-1 to 1-n in ST8. Send to (first
Confirmation command transmission means).

As a result, in the automatic change machines 1-1 to 1-n, the number data of stored coins counted by denomination in the stored coin number counting unit 40 is read out, and the POS interface 3 is used.
2 is sent back to the POS terminals 2-1 to 2-n via ST2. If the CPU 11 receives the stored coin number data by denomination within a predetermined time after transmitting the number confirmation command in ST9, the CPU 11 proceeds to ST10. The change buffer update process specifically shown in FIG. 7 is executed (storage unit for storing the number of coins stored by denomination).

That is, first, the number-of-stored-number data in the change buffer 70 is stored in the automatic change machine 1-1.
Rewrite the received coin number data of the corresponding denomination received from ~ 1-n. Also, the total amount of each denomination is calculated and rewritten.

Next, the number of sheets stored and the number of warnings are compared for each denomination. Then, when there is a denomination whose storage number is equal to or less than the warning number, the warning flag corresponding to the denomination is set to “1”, and the warning flag corresponding to the denomination whose storage number is larger than the warning number is set to “0”. Reset to "". If there are no denominations whose stored number is equal to or smaller than the warning number, the warning flags F corresponding to all the denominations are reset to “0”.

Thus, when the cashier finishes the present registration work and gives the coins, which have been discharged to the coin outlet 38, as a change to the customer together with the receipt, the cashier enters the merchandise sales registration work for the next customer.

If no discharge completion response is received from the automatic change machines 1-1 to 1-n within a predetermined time in ST7 of FIG. 6, the automatic change machines 1-1 to 1-n receive the response. Since there is a possibility that coins equivalent to a change of a fractional amount less than 1,000 yen have not been discharged, the display 19 is caused to display a display indicating an abnormality of the change machine, and then the present registration operation is terminated.

At this time, when no coin is discharged, the casher arranges coins corresponding to the change amount from the drawer 24 and delivers the coins together with the receipt to the customer.

If the data of the number of stored coins cannot be received from the automatic change machines 1-1 to 1-n within the predetermined time in ST9 of FIG. The registration work of is ended.

Further, the CPU 11 executes the work shown in the flowchart of FIG. 8 as a part of the work for the M-POS terminal 3 which is a higher model. That is, it is waiting to receive a command from the M-POS terminal 3 via the communication interface 15, and if the command is received and the command is a check command of the automatic change machine, the SP
It is determined whether or not the automatic change machine connected to the OS terminal is performing a dispensing process. Then, if the change data is transmitted in ST6 of FIG. 6 and then the reception of the discharge completion response is waited in ST7, the automatic change machine is in the process of dispensing, and the command is transmitted to the automatic change machine. Is determined to be impossible. In contrast,
During other periods, it is determined that a command can be transmitted to the automatic change machine (command availability determination means).

When a command can be transmitted, that is, when the automatic change machine is not performing a dispensing process, a command for confirming the number of stored coins is sent to the automatic change machines 1-1 to 1-n via the change machine interface 16. Transmit (second confirmation command transmission means).

Thus, the automatic change machines 1-1 to 1-n
In, the number data of stored coins counted by denomination in the stored coin number counting unit 40 is read and returned to the POS terminals 2-1 to 2-n via the POS interface 32. If the data of the number of stored coins by denomination is received within a predetermined time after the transmission of the number confirmation command, the same processing as the change buffer update processing specifically shown in FIG. 7 is executed.

Next, the inspection data of the automatic change machine is edited based on the storage contents of the change buffer 70 updated by the change buffer update processing. More specifically, the check data is read out from the change buffer 70 by reading the stored number of sheets, the total amount, and the warning flag, and further calculating the total change amount in the automatic change machine in which the total amount of the denominations is added to edit inspection data. Thereafter, if the inspection data of the automatic changer is transmitted to the M-POS terminal 3 via the communication interface 15 (first coin type storing coin number transmitting means), the process is terminated.

On the other hand, when the command cannot be transmitted,
That is, when the automatic change machine is in the process of dispensing, and when a command for confirming the number of stored coins is transmitted to the automatic change machines 1-1 to 1-n, but a response cannot be received within a predetermined time due to a communication error or the like. In the same manner as described above, based on the stored contents of the change buffer 70, edit the inspection data of the automatic change machine,
If the data is transmitted to the M-POS terminal 3 via the communication interface 15 (the second coin type stored coin number transmitting means),
This processing ends.

On the other hand, C of the M-POS terminal 3 which has transmitted the check command of the automatic change machine to each of the S-POS terminals 2-1 to 2-n.
PU51, as shown in FIG. 9, each S-POS terminal 2-1
It waits for the automatic change machine inspection data transmitted from .about.2-n to be received. Each time the inspection data is received, the received data is stored in the RAM 53.

When the inspection data is received from all the S-POS terminals 2-1 to 2-n, the received data is output to the printer 62 and a changer report 80 as shown in FIG. Output. That is, the number of coins stored in the automatic change machine by type of S-POS terminal, the total amount of the type of coins, and the total change are printed. Further, a warning mark “*” is also printed for the data of the denomination whose stored number is equal to or less than the warning number and the warning flag is set to “1”.

As described above, in this embodiment, each of the S-POS terminals 2-1 to 2-n, which is a cash register with an automatic changer, completes the sales registration of all the products purchased by one customer, and After the user has entered the deposit amount from the customer and declares the end of registration of one transaction by operating and inputting the closing key, a change operation for subtracting the total amount from the deposit amount is performed. When the change has a fractional amount of less than 1,000 yen, change data corresponding to the fractional amount is transmitted to the automatic changer connected to the S-POS terminal, and the change coin is transmitted from the automatic changer. Is automatically ejected.

When the dispensing process in the automatic change machine is completed, a command for confirming the number of stored coins is transmitted from the S-POS terminal to the automatic change machine. As a result, the data of the number of stored coins counted by denomination in the stored coin number counting unit 40 is transmitted from the automatic change machine, and the storage content of the change buffer 70 in the S-POS terminal is updated.

That is, the change coins are discharged from the automatic change machines 1-1 to 1-n connected to the change machine interface 16 to the change buffers 70 of the S-POS terminals 2-1 to 2-n, respectively. The number of stored coins of the later denomination is stored and managed. However, immediately after the cashier inserts the received coin or the supplementary coin after the change coin is ejected, the change buffer 70
Are different from the actual number data.

When the accountant, such as a store manager, checks the number of coins stored in each of the automatic change machines 1-1 to 1-n, each of the S-POS terminals 2-1 to 2-n A check command for the automatic change machine is transmitted from the M-POS terminal 3, which is a higher-order model. Then, each of the S-POS terminals 2-1 to 2-n
Then, whether or not a command can be transmitted to the automatic change machines 1-1 to 1-n, respectively, that is, the automatic change machines 1-1 to 1-n
It is determined whether is withdrawal processing.

If the payment is not being made, the SP
The OS terminal transmits a command for confirming the number of stored coins to the automatic change machine. As a result, the S-POS terminal responds to the S-POS terminal with data on the number of stored coins counted by denomination in the stored coin number counting section 40 from the automatic change machine. The inspection data of the machine is edited and transmitted to the M-POS terminal 3. Therefore, the inspection data in this case matches the number of coins stored in the automatic change machine at the present time.

On the other hand, when the dispensing process is in progress or when the number confirmation command is transmitted but there is no response from the automatic change machine, the S-POS terminal uses the automatic change machine based on the stored contents of the change buffer 70. The inspection data of M-
It is transmitted to the POS terminal 3. Therefore, the inspection data in this case does not always coincide with the number of coins stored in the automatic change machine at the present time, but there is no significant error and no problem.

Thus, from the M-POS terminal 3, each S-
The changer report 80 is printed out based on the inspection data received from the POS terminals 2-1 to 2-n, so that the accounting person can store the changer in each of the automatic changers 1-1 to 1-n based on the printout contents. The number of coins that have been used can be collectively concentrated and checked without omission.

As a result, as in the prior art, the accountant goes around the installation location of each of the automatic change machines 1-1 to 1-n and repeats the same key operation to store the automatic change machines in the automatic change machines 1-1 to 1-n. This eliminates the need to check the number of coins that have been performed, and thus has the effect of simplifying the time and effort required for checking the number of stored coins in each automatic change machine.

In the present embodiment, the warning buffer 70 stores the warning number for each denomination of coins stored in the automatic change machine.
When the number of sheets stored becomes equal to or less than the number of warnings, a warning flag in the buffer 70 is set. For the denominations for which the warning flag is set, a warning mark "*" is added on the changer report 80, and the number of stored money and the total amount are printed.

Therefore, the accountant only needs to recognize that the coins of the denomination to which the warning mark “*” has been added are in short supply and need to be replenished, and the replenishment of coins can be performed efficiently.

In the above-described embodiment, the upper model M
The POS terminal 3 outputs a report on the number of stored denominations and the like for each S-POS terminal based on the inspection data of the automatic changer received from each of the S-POS terminals 2-1 to 2-n. −P
Only the denominations for which the warning flag has been set for each OS terminal and the number of stored denominations may be extracted and output as a report.

By doing so, the denomination printed on the report is the denomination of coins that are insufficient in the automatic changer connected to the S-POS terminal, and the replenishment of coins can be performed more efficiently. You will be able to do well.

Further, the automatic change machine is not limited to one that handles only coins, and may be one that can handle bills.
In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0082]

As described in detail above, the cash register with an automatic changer of the present invention transmits a command for confirming the number of stored money to the automatic changer every time the change data is transmitted to the automatic changer. Each time the number data of the denominated storage currency transmitted from the automatic change machine in response to the number confirmation command is received, the latest received data is stored in the change buffer. Further, when an inspection command of the automatic change machine is received from the upper model via the transmission line, it is determined whether or not a command can be transmitted to the automatic change machine. When the command can be transmitted, a number confirmation command is transmitted to the automatic change machine, and in response to the number confirmation command, when the number data of the denominated storage coins transmitted from the automatic change machine is received, the reception is performed. The data is transmitted to the upper model via the transmission line. On the other hand, when it is determined that the command cannot be transmitted, and when the response data cannot be received from the automatic change machine in response to the transmission of the number confirmation command, the data stored in the change buffer is transferred to the host via the transmission line. It is sent to the model.

Therefore, according to the present invention, the number of stored coins for each denomination of the automatic change machine connected to each cash register is collectively concentrated by the upper model connected to each cash register via the transmission line. This makes it possible to provide a cash register with an automatic changer which can simplify the work of checking the number of stored coins in each automatic changer.
