DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a POS (Point-of-Sale Information Management) system, in which a single electronic cash register is installed together with a POS system. And a transaction data input device capable of inputting the total data for each transaction item to be collected by the controller.

[0002]

2. Description of the Related Art A store controller installed in a store office or the like and configured by a host computer and the like, and a plurality of POS terminals installed in each sales floor and registering products and the like purchased by customers are connected via a transmission line. Connect and each PO
The POS system, which enables the store controller to collect and aggregate the data of products registered at the S terminal for various transaction items and to easily analyze the sales of the entire store, is a mass sales system for supermarkets and convenience stores. Widely used in stores.

However, even in a store using the above-mentioned POS system, a POS terminal cannot be installed in a sales floor where transmission lines are difficult to be laid or in a sales floor where the layout is frequently changed. Was dealing with.

In a store where a single electronic cash register is installed together with the POS system,
It is desirable that merchandise sales data registered in the electronic cash register can be collected and totaled by the POS system controller together with the merchandise sales data registered in each POS terminal.

Conventionally, one of the POS terminals is provided with a function for inputting the accumulated data for each transaction item counted by the electronic cash register, and based on the report output by the settlement or the inspection work of the electronic cash register. When the operator inputs the total data for each transaction item from the keyboard of the POS terminal, the data can be collected by the controller. However, in this case, we did not automatically check the validity of the keyed cumulative data,
All the operations are left to the discretion of the operator, and even if the input total data is incorrect, the input is permitted as it is and collected by the POS system controller.

[0006]

As described above, in this type of conventional transaction data input device (one POS terminal is also used), the validity of the total data input for each transaction item is automatically checked. Since it is not possible and even if the data is incorrect, the input is permitted as it is, and there is a possibility that an erroneous totaling result may be output when the input total data for each transaction item is further externally totalized.

Accordingly, the present invention can automatically check the validity of the accumulated data for each transaction item input from the input unit, and informs the operator when incorrect data is input. It is an object of the present invention to provide a transaction data input device which can enable re-input of valid data and can increase the credibility of an external totalized result.

[0008]

According to the present invention, there is provided an input section for inputting total data for each transaction item totalized by an electronic cash register, and stores the total data for each transaction item input from this input section. A transaction comprising a storage unit, an external output unit for outputting the total data for each transaction item stored in the storage unit to the outside, a display unit for displaying the total data for each transaction item input from the input unit, and a printing unit. In the data input device, an arithmetic expression storage means for storing an arithmetic expression having a term and a solution based on the cumulative data of the relevant transaction item among the transaction items, and an arithmetic expression when the cumulative data for each transaction item is inputted from the input unit. A data extracting unit for extracting, from a storage unit, terms of the arithmetic expression stored by the storage unit and cumulative data of each transaction item constituting a solution; and executing the arithmetic expression with the cumulative data extracted by the extracting unit. Data checking means for checking the validity of the accumulated data of each transaction item, and a notifying means for notifying that an input error has occurred if the accumulated data is determined to be an invalid value by this checking means. Things. Here, it is desirable that the arithmetic expression storage means be a check table that stores the arithmetic expressions in a rewritable manner, and that the arithmetic expressions can be arbitrarily set and changed.

[0009]

According to the present invention having such a configuration, the operator inputs the total data for each transaction item totalized by the electronic cash register from the input section. Then, the input data is stored in the storage unit for each transaction item. Then
The input data of the corresponding item is extracted from the storage unit based on the arithmetic expression set according to the relevance of each transaction item, and the corresponding arithmetic expression is executed by the input data, and the validity of the input data is determined by the operation result. Checked. Here, when it is determined that the input data is an invalid value, the fact that there is an input error is notified, and the operator performs data input again. In this way, when all valid data is input for each transaction item, the input data is output from the external output unit for counting at a higher order.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, in a store in which a single electronic cash register is installed together with the POS system, one of the POS terminals also has a function of inputting the total data for each transaction item counted by the electronic cash register. The case will be described.

FIG. 2 is a block diagram of the POS system. The store controller 1 is installed in a store office or the like and includes a host computer and the like, and a plurality of units are installed in each sales floor and register products purchased by customers. POS terminal 2
-1, 2-2, 2-3... Via a transmission line 3 and each P
The store controller 1 collects and totals data of commodities registered at the OS terminals 2-1, 2-2, 2-3,... For various transaction items so that sales analysis of the entire store can be easily performed. It is configured. The POS terminal has a function of inputting the total data for each transaction item, which is counted by a single electronic cash register for one 2-1 of the POS terminals.

FIG. 1 shows each POS terminal 2-1, 2-2, 2
-3... In the CPU (Central Processing Unit) 11 constituting the control unit main body via the bus line 12.
A ROM (read only memory) 13 storing program data for executing various business modes such as "check", "payout", "setting", etc., and various memory areas for registering merchandise sales data are provided. A RAM (random access memory) 14 to be formed, a clock circuit 15 for measuring the current date and time, and a signal for a mode switch 16 for selecting the above-mentioned business mode are inputted and the cash and the like are stored. An I / O port 18 for outputting an opening command signal to the drawer 17, a keyboard controller 20 for receiving a key signal from a keyboard 19, and a display for driving and controlling a display 21 to display characters, numerals, etc. corresponding to the display data. Drives the controller 22 and the printer 23 to print characters, numerals, etc. corresponding to the print data on receipt paper or the like. Both printer controller 24 that controls the issuance of the receipt, which are connected respectively to each part such as a communication interface 25 for controlling data transmission and reception performed between the said store controller 1 via the transmission line 3.

As shown in FIG. 3, in addition to the numeral keys 31 of "00", "0" to "9", the keyboard 20 has a PLU (price look up) key 32 and an amount key 33. , "X" multiplication key 34, subtotal key 35, deposit / current total key 36, return key 37, # key 38, "responsibility" sign key 39, "C" clear key 40, "exchange" exchange key Various function keys such as 41 are provided.

In the RAM 14, as shown in FIG. 4, a transaction totaling table for cumulatively storing the amounts of merchandise registered for each transaction item such as total sales amount, net sales amount, returned sales amount, and total tax amount. 51 are formed. here,
Each transaction item is assigned a series of transaction numbers.

When a product is registered by a key operation of the keyboard 19 in the "registration" operation, the CPU 11 accumulates the data of the registered product in the transaction-specific aggregation table 51 for each transaction item. For example, if sales of taxable goods are registered, the sales amount including tax of the registered goods is added to the total sales amount of transaction number "1", and the sales amount excluding tax is added to the net sales amount of transaction number "2". Then, the tax amount is added to the total tax amount of the transaction number “4”. In the case of a foreign tax product, the tax amount is added to the total foreign tax amount of the transaction number "6", and in the case of a tax-inclusive product, the tax amount is added to the total tax amount of the transaction number "5". When the merchandise returns are registered, the return amount of the registered merchandise is subtracted from the total sales amount of the transaction number “1” and added to the total returned amount of the transaction number “3”.

Thus, each of the POS terminals 2-1 and 2-
The total data for each transaction item totaled in the transaction totaling table 51 of 2, 2-3 ... is transmitted to the store controller 1 via the communication interface 25 and the transmission line 3 in response to a data collection request from the store controller 1. Sent.

On the other hand, in the POS terminal 2-1 provided with a function of inputting the total data for each transaction item which is counted by a single electronic cash register, the above R
The AM 14 has a check table 52 shown in FIG. The check table 52 includes an area 52a for setting and storing a transaction number corresponding to a series of check numbers.
And an area 52b for setting and storing an operation formula created in accordance with the relevance of other transaction items with respect to the transaction item of the transaction number set in the area 52a. Is the sum of the net sales amount of transaction number "2" and the total tax amount of transaction number "4" minus the total amount of returns for transaction number "3". A transaction number “1” and an arithmetic expression [“2” + “4” − “3”] are set corresponding to “1”, and the net sales amount of the transaction number “2” is the same as that of the transaction number “1”. Since the total tax amount of the transaction number "4" is subtracted from the total sales amount and the total amount of the returned goods of the transaction number "3" is added to the total amount, the transaction number "2" of the check table 52 corresponds to the check number "2". 2 ”and the arithmetic expression [“ 1 ”−
"4" + "3"], and the total tax amount of transaction number "4" is the sum of the total tax amount of transaction number "5" and the total tax amount of transaction number "6" Therefore, the transaction number “4” and the arithmetic expression [“5” + “6”] are set corresponding to the check number “3” in the check table 52.
Here, the data setting in the check table 52 is as follows.
It is arbitrarily performed by a key operation of the keyboard 19 in the “setting” operation, and the change is easy.

When the # key 38 is operated in the "check" or "pay-out" operation, the CPU 11 of the POS terminal 2-1 receives a transaction item counted by a single electronic cash register. It becomes the mode to input the total data of. When this mode is selected,
First, the data in the transaction amount area 51a in the transaction totaling table 51a is evacuated to another area. After evacuation,
Transaction number "1" in the transaction-specific aggregation table 51a
Is displayed on the display 21.
In this state, when the numerical data is input by the numeric key 31 and the subtotal key 35 is subsequently operated, the numerical data is set as the total amount of the corresponding transaction item “total sales amount” in the transaction totaling table 51. It is stored in the area 51a. Further, the transaction name “net sales amount” of the transaction number “2” is displayed on the display device 21 and the next key input is awaited. In this way, the input of the total data is prompted in the order of the transaction numbers, and the total data input by key is stored in the transaction amount area 51a of the transaction totaling table 51 for each transaction item.

Similarly, when the sign key 39 is operated in the input mode, the CPU 11 executes the control shown in the flowchart of FIG. That is, ST (step) 1
To initialize the check number counter N to "1". Next, as ST2, the setting data (transaction number, arithmetic expression) of the check number corresponding to the counter N is read from the check table 52. Then, as ST3, the input amount (transaction amount area 51a) of the transaction number which is the solution of the arithmetic expression in the above set data from the transaction total table 51.
And the input amount of each transaction number constituting the term of the operation formula is extracted as ST4. (Data extraction means)

Next, as ST5, the corresponding arithmetic expression is executed with the input amount extracted in ST4, and the arithmetic result and S
A comparison is made with the input amount extracted at T3. (Data check means)

If the two values match in ST6, the extracted input amount is key-input as valid total data, and the counter N is incremented by "+1" in ST7.
Then, the process returns to ST2 to repeat the above processing.

On the other hand, if the two do not match in ST6, at least a part of the extracted input amount has been key-inputted as incorrect total data, so an error flag is set in ST8 and the printer 2 is set in ST9.
3 is driven and error information such as the difference obtained by comparison is printed out on a receipt paper. Then, after updating the counter N by "+1" in ST7, the process returns to ST2 and repeats the above processing.

When all data set in the check table 52 have been checked in ST8, an error flag is checked in ST9. here,
If the flag is set, an input error has occurred, so that the printer 23 is driven and an error receipt 70 as shown in FIG. 7 is issued (notification means), and this processing ends.

On the other hand, if the error flag has been reset, no input error has occurred, and a message indicating that the input has been normally made is displayed on the display unit 21.
This processing ends.

When the process is normally completed, the contents of the transaction-specific total table 51a are transmitted to the store controller 1 via the communication interface 25 and the transmission line 3 after waiting for a data collection request from the store controller 1. The program is programmed to restore data saved in another memory after transmission.

Here, the keyboard 19 of the POS terminal 2-1 functions as an input section for inputting the total data for each transaction item counted by the electronic cash register, and the transaction-specific counting memory 51 receives the data from the input section. The communication interface 25 functions as a storage unit that stores the input data for each transaction item, and the communication interface 25 functions as an external output unit that outputs the input data stored in the storage unit to the outside.

As described above, in this embodiment, when the store controller 1 attempts to collect the total data for each transaction item that is totaled by a single electronic cash register, the operator first checks the electronic cash register. Get a report or checkout report. afterwards,
When the operation mode of the POS terminal 2-1 is switched to the input mode of the total data, the user operates the keyboard to input the corresponding total data for each transaction item.

In this case, the operator inputs the total data of the corresponding transaction items in the order of the transaction numbers in the transaction totaling table 51. Thus, the input data is stored in the transaction amount area 51a of the transaction totaling table 51 in the order of input.

When the data input is completed for all the items, the sign key 39 is operated by a key to check the validity of the input data. Then, the input data stored in the transaction amount area 51a of the transaction totaling table 51 is sequentially extracted based on the transaction number and the arithmetic expression set in the check table 52, and the arithmetic expression is executed to validate the input data. Sex is checked. Then, as a result of the check, if it is determined that all the input data are valid, the fact is displayed on the display 21 and the operator confirms the validity of the data.

On the other hand, if there is an input error in at least one data, an error receipt 70 as shown in FIG. 7 is printed and issued. Accordingly, the operator confirms which item of the error receipt 70 has been input incorrectly from the printed content, and re-inputs the error item. In the case of FIG. 7, while the total tax amount of the transaction number “4” is “2523 yen”, the transaction number “5”
Despite the fact that the total amount of tax included is “999 yen”, the total amount of foreign tax of transaction number “6” is “1526 yen”, and the total tax amount is the sum of the total amount of the internal tax and the total amount of foreign tax There is a difference of 2 yen. Therefore, it is understood that at least one of the total tax, the total internal tax, and the total external tax is incorrectly input.

As described above, according to the present embodiment, an arithmetic expression is created according to the relevance of each transaction item, and the arithmetic expression is set in the check table 52, so that the calculation is performed by a single electronic cash register. It is possible to automatically check input errors when entering the accumulated data for each of the transaction items. Therefore, it is possible to prevent a problem that invalid data is collected as it is in the store controller 1 as the total data for each transaction item collected by the electronic cash register. As a result, the credibility of the data collected / aggregated by the store controller 1 is enhanced, and accurate sales analysis and the like can be performed. In addition, since the input data is automatically checked, the operator can input the data with ease, and the operation for checking is very simple, so that the burden on the operator can be greatly reduced.

Further, since the calculation formula created according to the relevance of each transaction item is set in the check table 52 of the RAM 14, the calculation formula can be arbitrarily changed. Therefore, depending on the store, for example, there are cases where a tax amount is added to the total sales amount and cases where it is not added, but such a difference in operation can be easily coped with.

Further, there are items that need not be checked depending on how the arithmetic expression is created. Therefore, the number of areas set in the check table 52 does not always need to be the same as the number of transaction items in the transaction totaling table 51. It does not affect the cost.

In the above-described embodiment, the case of inputting the total amount data of the transaction items is shown. However, when inputting the total data such as the number of registered points, the number of transactions, the number of customers, etc. You can check. Further, in the above-described embodiment, the POS terminal 2-1 is also used as a transaction data input device, but a dedicated model may be used as the transaction data input device. In this case, the above-mentioned dedicated machine is connected to the transmission line 3 and the store controller 1 collects input data via the transmission line 3 and a method for constructing a single unit and inputting it to an external storage medium such as a floppy disk or a memory card. There is a method in which data is output, and the data is collected by setting the external storage medium in a floppy disk driver or a card reader of a store controller and reading the stored contents. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0035]

As described in detail above, according to the present invention, the validity of the total data for each transaction item input from the input unit can be automatically checked, and when the invalid data is input. Can provide a transaction data input device that can notify the operator of the fact and enable re-input of valid data, and can enhance the credibility of the external total result.

In addition, by providing a check table for arbitrarily setting an arithmetic expression created in accordance with the relevance of each transaction item, there is an advantage that it is possible to easily cope with a difference in operation between stores.
