DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales data processing apparatus used in a store where a plurality of merchandise sales data registration terminals are used, such as a fast food store, but the number of receipts is small.

[0002]

2. Description of the Related Art In general, in a fast food store, a counter is provided with a plurality of terminal units for registering product sales data called POS (point of sale information) terminals, and several clerks place orders for customers across the counter. You can receive it. Each store clerk inputs the product sales data ordered by the customer to a nearby product sales data registration terminal, and when all the products ordered by one customer have been input, the closing operation of the registration is performed at the terminal. I do. As a result, the registered total amount of the customer and the like are displayed on the display unit of the terminal, so that payment corresponding to the total amount is received.

By the way, some stores of this type do not issue a receipt to a customer to improve customer judgment and reduce costs. Therefore, as a terminal for registering merchandise sales data for a store, a simplified terminal without a printer for printing a receipt has been developed.

[0004]

However, since some of the customers request a receipt, it is difficult to use the above-mentioned simple type terminal, and generally, a relatively expensive printer having a printer connected inside or outside is used. The fact is that terminal equipment is used, and wasteful capital investment has been forced.

[0005] Accordingly, the present invention provides a method of setting n (n
≧ 3) (n−) of the product sales data registration terminals
1) A merchandise sales data processing device capable of promptly and surely responding to an unexpected receipt issuance request as long as at least two of the units are provided with a printer, and capable of reducing equipment costs without lowering serviceability. It is intended to provide.

[0006]

According to the present invention, merchandise sales data input by an input operation is registered in a storage unit, and registered total data of one customer is displayed on a display unit in response to an operation of closing the registration. In a merchandise sales data processing device in which n (n ≧ 3) merchandise sales data registration terminals are electrically connected to each other via a transmission line, the number of the n merchandise sales data registration terminals is (N-1) At least two of the (n-1) printers are provided with a printer, and n customer sales data registration terminals are provided with one customer's receipt obtained according to the input operation and the registration closing operation of the product sales data. A print buffer for storing print data and a selection unit for selecting whether or not to perform receipt printing are provided. Then, among the n merchandise sales data registration terminals that do not have a printer, at least two terminals having a printer are provided when the execution of receipt printing is instructed by the selection means.
Command transmission means for transmitting a print request command to one of the terminals, and another terminal equipped with a printer upon receiving a response to disallow use of the printer as a result of transmitting the print request command. Second command transmitting means for transmitting a print request command to the printer, and print data transmission for transmitting the contents of the print buffer to a terminal to which the print request command is transmitted upon receiving a use permission response of the printer as a result of transmitting the print request command. Means are provided. On the other hand, a terminal equipped with a printer is provided with first printer checking means for checking whether or not the own printer can print when receipt printing is instructed by the selecting means, and printing by the first printer checking means. When the possibility is confirmed, the contents of the print buffer are printed out by the printer of the machine itself, and the data is printed on the other terminal equipped with the printer when the print failure is confirmed by the first printer investigation means. A command transmission means for transmitting a request command; a print data transmission means for transmitting the contents of the print buffer to a terminal to which the print request command is transmitted upon receiving a printer use permission response as a result of transmitting the print request command; A second printer checking means for checking whether or not the printer of the own device can print when receiving a print request command via the second printer; A response transmitting means for transmitting a use permission response when confirming that printing is possible by the investigation means and transmitting a use disapproval response when confirming that printing is impossible, and transmitting the print data to the own printer when receiving print data via a transmission path. And data printing means for other devices to print out the data.

[0007]

[0008]

According to the present invention having such a configuration, each of the merchandise sales data registration terminals sequentially stores receipt print data in the print buffer based on the input of the merchandise sales data by an input operation. When a registration closing operation is performed, receipt print data based on the registered total data is stored in the print buffer. When the execution of receipt printing is selected by the selection means, the terminal connected to the printer prints out the contents of the print buffer by the printer. On the other hand, a terminal to which the printer is not connected transmits the contents of the print buffer to a terminal to which the printer is connected via a transmission path. In a terminal connected to the printer, the content received via the transmission path is printed out by the printer.

In this case, it is diagnosed whether or not the printer can be used normally. If the printer cannot be used, the contents of the print buffer are similarly transmitted to a terminal connected to another printer via a transmission line. Will do.

[0010]

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

In this embodiment, as shown in FIG.
Terminals (hereinafter simply referred to as terminals in this embodiment) 1-1 to 1-8 are electrically connected to each other via a transmission line 2, and the terminals 1-1 are registered. 1-3 are set in the first group, and a printer 3-1 for receipt printing is connected to one of them (in this case, terminal 1-3).
Two other terminals 1-4 and 1-5 are set in the second group, a printer 3-2 for receipt printing is connected to one of them (in this case, terminal 1-5), and the remaining terminals are connected. Commodity sales data in which three terminals 1-6 to 1-8 are set in a third group and one of them (in this case, terminal 1-6) is connected to a printer 3-3 for printing receipts The processing device will be described.

FIG. 2 is a block diagram showing the configuration of the terminals 1-1 to 1-8. In the figure, reference numeral 11 denotes C constituting the control unit main body.
A PU (Central Processing Unit) 12 is a ROM in which program data for the CPU 11 to control each unit is stored.
(Read Only Memory) and 13 are RAMs (random access memories) in which various memory areas used for the arithmetic processing of the CPU 11 are formed. Is composed. Then, a clock circuit 15 for clocking the date and time in the microcomputer, "registration", "check", "payment"
A drawer opening device 18 for receiving a signal from a mode switch 16 for switching various business modes such as "setting" and opening a drawer 17 for storing cash or the like.
I / O port 19 that outputs a drive signal to
1, a department controller key K2, a closing key K3, etc., a keyboard controller 21 to which a key signal is input from a keyboard 20 on which a printing key K4 as a selection means for selecting whether or not to perform receipt printing is provided. A display controller 23 for driving and controlling a display 22 for displaying a customer's total amount, etc .; and a printer 3-1 to 3-3 for printing a receipt.
A printer interface 24 to which is detachably connected,
An in-line interface 25 for controlling data transmission / reception performed via the transmission line 2 is connected to each other so as to function as terminals 1-1 to 1-8.

As shown in FIG. 3, the RAM 13 has a merchandise registration memory 31 for cumulatively registering merchandise sales data, for example, for each department, a total amount memory 32 for storing the total amount of one customer, A print buffer 33 for storing receipt print data of one customer obtained in accordance with sales data input operation and registration closing operation, a flag memory 34 for storing a print flag F which is set (1) when receipt printing is possible, An output destination table 35 is formed in which the identification number (ID No.) of the terminal as the output destination of the receipt print data is set and stored in accordance with the priority order.

In the output destination table 35, the identification numbers of the terminals to which the printers in the same group are connected are set in advance in the output destination table 35 corresponding to the first priority, and are set to the second or lower priority. Is set to an identification number of a terminal to which a printer of another group is connected.

The CPU 11 has a mode switch 1
When the section key K2 of the keyboard 20 is operated in the state where the "registration" mode is selected by 6, the section key processing shown in FIG. 4 is executed because the section of the product purchased by the customer is input. That is, as the display processing, the numerical data by the numeric key K1 is recognized as the sales price of the product, and is displayed on the display 22. As a registration process, the sales amount is cumulatively registered in the product registration memory 31 for each input department, added to the contents of the total amount memory 32, and the value after the addition is stored in the total amount memory 32 again. Further, the product detail data including the input department, the sales amount, and the like are sequentially stored in the print buffer 33 as receipt printing data based on the product sales data, and the process ends.

In the case of a customer's first product registration,
Prior to the above-described display processing, the total amount memory 32 and the print buffer 33 are cleared, and the print flag F in the flag memory 34 is reset (0).

The CPU 11 has a mode switch 1
When the closing key K3 of the keyboard 20 is operated in the state where the "registration" mode is selected by the user 6, the closing key processing shown in FIG. 5 is executed because the closing operation of registration for one customer has been performed. That is, first, it is confirmed that the registration of the product purchased by the customer has been completed, and the print flag F
Is set (1). Next, the content of the total amount memory 32 is displayed on the display 22 as the total amount of the customer. Further, the registered total data such as the total amount is stored in the print buffer 33 as receipt printing data,
This processing ends.

When the print key K4 of the keyboard 20 is operated while the "registration" mode is selected by the mode switch 16, the CPU 11 instructs the execution of receipt printing. Perform key processing. That is, first, the state of the print flag F is checked. If the flag F is reset, the print key K4 is operated when receipt printing is not possible, so that the key input is regarded as an error and the process is terminated.

When the print flag F is set, the output destination table 35 is examined, and first, the identification number of the terminal having the highest priority is read. If the read identification number matches the identification number set in the own device, one of the printers 3-1 to 3-3 is connected to the printer interface 24 of the own device. The self-printing process shown in FIG. 7 is executed. That is, if it is confirmed that any one of the printers 3-1 to 3-3 is securely connected to the printer interface 24, it is checked whether or not the printer is busy (first printer check). means). If the printer is not in the busy state, the contents of the print buffer 33 are printed out on receipt paper by the printer (own data printing means), and the process is terminated.

If the identification number read from the output destination table 35 does not match the identification number set in the own device, the printer 3-1 is sent to the printer interface 24 of the other device.
Since any one of the printers 3 to 3 is connected, the printing process for another device shown in FIG. 8 is executed. That is, a print request command is transmitted to the transmission path 2 via the in-line interface 25 (first command transmission means). in this case,
The output destination table 3 as the destination address of the command
The identification number read from 5 is used. Accordingly, when a normal response indicating permission to use the printer is received from the terminal, the contents of the print buffer 33 are transmitted to the terminal via the in-line interface 25 and the transmission path 2 (print data transmitting means). This processing ends.

When the printer is not properly connected in the printing process of the own device or when the busy state continues for a certain period of time, the next priority identification number is read from the output destination table 35. Then, using the identification number read from the output destination table 35 as the destination address of the command, the inline interface 25 is used.
A print request command is transmitted to the transmission path 2 via the command line (command transmission means). If a normal response indicating permission to use the printer is received from the corresponding terminal, the print buffer 3
3 to the in-line interface 25 and the transmission path 2
And sends the print data to the corresponding terminal (print data transmission means), and terminates this processing. Also, when an abnormal response other than the busy response is received in the printing process for another device, or when a busy response is received continuously for a certain period of time, the identification number of the next priority is read from the output destination table 35. Then, a print request command is transmitted to the transmission path 2 via the in-line interface 25 using the identification number read from the output destination table 35 as a command transmission destination address (second command transmission means). Accordingly, when a normal response indicating permission to use the printer is received from the terminal, the contents of the print buffer 33 are transmitted to the terminal via the in-line interface 25 and the transmission path 2 (print data transmitting means). This processing ends. It should be noted that if printing cannot be performed on all terminals for which the identification numbers are set in the output destination table 35, an error is generated.

On the other hand, the CPU 11 of the terminal that has received the print request command via the in-line interface 25
Executes the processing shown in FIG. That is, after confirming that the printer is connected to the printer interface 24, it is checked whether the printer is normal or the printer is operating and busy (second printer checking means). If the printer is abnormal or busy, an abnormal response or a busy response is returned (response transmitting means), and the process ends.

On the other hand, when the printer is operating normally and is not in the busy state, the printer can be used and a normal response is returned (response transmitting means).
Then, the receipt print data received via the in-line interface 25 is printed out on receipt paper by the printer (other-device data printing means), and this processing is terminated.

In this embodiment constructed as described above, when a department key of a product purchased by one customer is registered by inputting the department key K2 of each of the terminals 1-1 to 1-8, the registered product is registered. Are sequentially stored in the print buffer 33. When the user closes the registration by inputting the closing key K3, the registered total data of the customer is stored in the print buffer 33.

In this state, when the print key K4 is input and operated, the printer 3-1 and 3--
In the terminals 1-3, 1-5, and 1-6 to which the terminals 2 and 3-3 are connected, the contents of the print buffer 33 are respectively converted into receipt paper by the printers 3-1 and 3-2 and 3-3. It is printed out and a receipt is issued.

On the other hand, terminals 1-1 and 1- 1 not connected to a printer
In 2, 1-4, 1-7, and 1-8, terminals 1-3, 1-5, and 1-to which printers 3-1, 3-2, and 3-3 in the same group are connected, respectively. The contents of the print buffer 33 are transmitted to 6 via the transmission path 2. As a result, the terminal 1-
At 3, 1-5, and 1-6, the received contents are printed out on receipt paper by the printers 3-1, 3-2, and 3-3, and receipts are issued.

For example, if a printer is not connected to the terminal 1-3, or if printing is impossible due to a failure or the like even if the printer is connected, the terminal 1-3 and each terminal in the same group are not connected. Receipt print data generated from 1-1 and 1-2 is transmitted to other printer-connected terminals 1-5 and 1-6 via the transmission path 2 in accordance with a preset priority and receipt issuance is performed. Will be Terminal 1-5 or Terminal 1-6
The same applies to the case of.

If the operation shifts to the registration of the next customer without inputting the print key K4, the contents of the print buffer 33 are cleared in response to the first product registration of the next customer. Receipts for customers will not be issued.

Therefore, according to the present embodiment, it is possible to quickly respond to an unexpected receipt issuing request without connecting a printer to all of the terminals 1-1 to 1-8 installed in the store. . As a result, many relatively inexpensive terminals to which no printer is connected can be used, and equipment costs can be reduced. Further, by providing a printer backup function, there is an advantage that confusion at the time of printer failure can be prevented.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, an example has been described in which eight terminals are divided into three groups and a printer is connected to one of the groups. However, it is not always necessary to divide the groups. Further, a printer may be connected to two or more printers in the same group so that backup can be performed in the group.

In the above embodiment, print data is printed on receipt paper. However, a printer for printing on slip paper is connected externally, and each terminal stores slip print data in the print buffer 33. Alternatively, print processing may be performed in the same manner as in the present embodiment. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention, such as the number of terminals and the number of printers.

[0032]

As described above in detail, according to the present invention, at least two out of (n-1) of n (n.gtoreq.3) product sales data registration terminals installed in a store. As long as the table is equipped with a printer, it is possible to provide a merchandise sales data processing apparatus that can promptly and surely respond to an unexpected receipt issuance request and that can reduce equipment costs without lowering serviceability.
