DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales registration data processing device used as a so-called POS terminal for merchandise sales registration of a POS (point of sale information) system used in department stores and the like.

[0002]

2. Description of the Related Art FIG. 4 shows the general configuration of a general POS system used in department stores and the like. That is, this POS
The system connects a plurality of POS terminals 1 installed in each sales floor and a store processor 2 as a higher-level device for centrally controlling these POS terminals 1 to an HDLC (High Level Data Link Control) line or the like. Are connected in a closed loop through the transmission path 3 of FIG.

Each POS terminal 1 is constituted by an electronic cash register or the like, and includes a CPU (Central Processing Unit),
A control unit is formed by ROM (Read Only Memory), RAM (Random Access Memory), etc.
Equipped with input / output devices such as a keyboard, a display, and a printer. Further, a communication interface for controlling data transmission through the transmission path 3 is provided.

The store processor 2 is composed of a computer or the like, and forms a control unit with a CPU, a ROM, a RAM, and the like, and has input / output devices such as a keyboard, a display, a printer, a hard disk device, and a floppy disk device mounted thereon. I have. Further, a communication interface similar to each POS terminal 1 is provided.

[0005] The store processor 2 is configured as shown in FIG.
As shown in (a), corresponding to a product code (for example, 12 digits) attached to each product, a sales floor code (for example, 4 digits) of a sales floor where the product is sold, and an attribute code of a classification to which the product belongs (For example, 4 digits), product data 41 such as name data of the product, digit number limit data of the product, and status data are set in advance, and sales accumulation data obtained by accumulating the number of sales points and the sales amount of the product, respectively. The product file 4 storing the file 42 is formed in, for example, a hard disk device.

[0006] Here, the status data is defined as shown in FIG.
As shown in (b), “automatic discount category” indicating “0” without automatic discount or “1” with automatic discount, “automatic discount data” indicating discount data with automatic discount, tax type (excluding tax, "Tax category" indicating tax-inclusive, tax-exempt), "tax rate" indicating the tax rate of taxable goods, "discount availability flag" indicating discount permission "0" or prohibition "1" at the sales floor, discount permission at the sales floor " It consists of data of various items such as a “discount permission flag” indicating “0” or prohibition “1”.

[0007] The commodity code is a small classification code,
The attribute code may be a large classification code.

[0008] A clerk who operates the POS terminal 1 at each sales floor and performs the accounting operation for the customer purchased product, a so-called cashier, operates the keyboard and scanner of the POS terminal 1 when the customer offers the accounting for the purchased product. Then, enter the product code, sales floor code, quantity, price, etc. of the customer purchased product.

[0009] Then, the control unit of the POS terminal 1 determines the line state with the store processor 2. When the line connection state (inline) is confirmed, an inquiry message is created using the input product code and sales floor code as a search key, and the inquiry message is stored in the store processor via the communication interface and the transmission line 3. Send to 2.

When the control unit of the store processor 2 receives the inquiry message from the POS terminal 1, it searches for a product file using the search key in the inquiry message. Then, the product data 4 of the product code and the sales floor code that match the search key
When 1 is read, an acknowledgment message (ACK) including the product data 41 is created, and the acknowledgment message is transmitted to the corresponding POS terminal 1 via the communication interface and the transmission path 3. If the merchandise item data 41 matching the search key could not be read, the negative response message (N
AK) to the corresponding POS terminal 1.

When the control unit of the POS terminal 1 inquiring of the store processor 2 receives the acknowledgment message from the store processor 2, it analyzes the product data 41 in the acknowledgment message. Then, for example, when the status data has an automatic discount section, the price input by the key is discounted by the automatic discount data to obtain the sales amount.
If the tax category is a foreign tax, the tax amount is obtained from the price and the tax rate.

In addition, when discount data of a customer purchase item is inputted by a key operation on a keyboard, a discount permission flag is checked in status data, and discount processing is executed if discount is permitted, and discount data is input if discount is prohibited. Error. Similarly, when the discount data of the customer purchased product is inputted by key operation, the discount flag is checked in the status data, and if the discount is permitted, the discount processing is executed; if the discount is prohibited, the discount data is executed. Make the input an error.

When the sales data and the sales data of the sales amount of the customer purchased product are obtained based on the product data 41 and the input data from the keyboard, the sales data is stored in the attribute code totalizer in the RAM. Perform registration processing for each attribute code. In addition, sales transaction data including a product code, a sales floor code, the number of sales points, an amount, and the like of the customer purchase product is stored in the transaction buffer.

The sales transaction data of each customer purchased item stored in the transaction buffer is collected by the store processor 2 through the transmission line 3 at appropriate times, and added to the sales accumulation data 42 corresponding to the corresponding item code in the item file 4. You.

By the way, the line between the POS terminal 1 and the store processor 2 may be disconnected (off-line) due to disconnection of the transmission line 3 or abnormality of a connector connecting the transmission line 3 and the communication interface. At this time, PO
The S terminal 1 cannot make an inquiry to the store processor 2 even if the customer purchased commodities are registered, and cannot acquire the commodity data 41 on the commodity file 4.

Therefore, in this type of conventional POS terminal 1, a sales floor / attribute correspondence table for converting a sales floor code into an attribute code is provided on a RAM, and the corresponding sales floor code is referred to by an input sales floor code when offline. To determine the attribute code. In addition, sales data is acquired by key input data with all status data set to “0”. Then, the sales data is registered in the attribute code-based totalizer in accordance with the attribute code determined with reference to the correspondence table.

[0017]

However, the conventional off-line processing method described above has the following problems. That is, the attribute codes of the products sold at one sales floor are not always the same. In addition, some customers may offer to pay for products sold at different sales floors. For this reason, it is difficult to uniquely determine the attribute code of the customer-purchased product from the sales floor code. Nevertheless, conventionally, the attribute code is determined by referring to the sales floor / attribute correspondence table based on the input sales floor code, and the sales data of the customer-purchased merchandise is registered for each attribute code. The reliability of the data of the attribute code-based totalizer in the POS terminal 1 has been reduced.

Further, since all status data are processed as "0" at the time of off-line, for example, all discount enable / disable flags and discount enable / disable flags are processed as "permitted". For this reason, for example, there is a case where a product for which a discount prohibition (a discount enable / disable flag = 1) is specified in the product file 4 in the store processor 2 is allowed to be discounted at the counter when offline.

Therefore, the present invention is to provide a product sales registration data processing apparatus capable of executing the same accurate sales data registration processing of a sales product as at the time of in-line even if the line status with the host device changes from in-line to off-line. It is assumed that.

[0020]

SUMMARY OF THE INVENTION The present invention relates to a merchandise sales registration data connected via a transmission line to a higher-level device having a merchandise file in which merchandise data such as a code, a name, and a status of each merchandise is set and stored in advance. In the processing device, an off-line table for accumulating product data of each product, code input means for inputting the code of the sales product, and a line for determining a line state with a higher-level device when the code is input by the code input means Discriminating means, query processing means for inquiring the higher-level device using the code as a search key when the line connection state with the higher-level device is confirmed by the line determining means, and receiving product data of the sales product; In-line registration processing means for registering sales data of sales products based on the received product data, and inquiry processing means Each time product data is received, a data determination unit that determines whether or not product data having the same code as the received product data is stored in the offline table, and the data determination unit determines that the product data having the same code is not stored. Product data adding means for adding the received product data to the offline table, and when the data determining means determines that the product data of the same code is already stored, the content of the product data corresponding to the same code is updated to the content of the received product data. Product data updating means, table search means for searching an offline table using a code as a search key when a line disconnection state is confirmed by the line determination means, and a code corresponding to the result search key of the search means Is detected, the sales data of the sales product is It is obtained by a offline registration processing means for recording process.

[0021]

According to the present invention having such a configuration, when a code of a product for sale is inputted by the code input means at the time of a line connection state with a higher-level device, so-called in-line, an inquiry is made to the higher-level device using the code as a search key. Do. Then, when the product data of the sales product is received as the response data, the sales data of the sales product is registered based on the product data.

At this time, the offline table is searched to determine whether or not merchandise data having the same code as the received merchandise data is stored. If not stored, the received product data is added to the offline table.
On the other hand, if it is stored, the content of the product data corresponding to the same code is updated to the content of the received product data. Therefore, the latest product data of each sales product registered at the time of in-line is accumulated in the offline table.

On the other hand, when the code of the sales product is input by the code input means in a state where the line is not connected to the host device, that is, when the device is offline, the offline table is searched using the code as a search key. Then, when a code matching the search key is detected, sales data of the sales product is registered based on the product data corresponding to the code.

Therefore, even if the status changes from in-line to off-line, the sales data of the sales product is registered based on the product data which is assumed to be responded from the host device at the time of in-line.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which a merchandise sales registration data processing apparatus of the present invention is applied to a POS terminal 1 of a POS system shown in FIG. 4 will be described below with reference to the drawings.

Note that the configuration of the store processor 2 in the POS system and the configuration of the product file 4 provided in the store processor 2 are the same as those in the related art.
And its description is omitted.

FIG. 1 is a block diagram showing a main configuration of a POS terminal 1 according to the present invention. This POS terminal 1 has a CP
U11, ROM12, and RAM13 constitute a control unit. A clock circuit 14 for measuring the current date and time;
Communication interface 15, which controls data transmission through
Keyboard controller 16, display controller 1
7, a printer controller 18, an I / O port 19, and the like, and these are connected to the control unit by a bus line 20 such as a data bus.

The POS terminal 1 includes a product registration key for inputting a product code, a sales floor code, a quantity, a price, and the like of a product for sale, a function key for inputting discount data, discount data, and the like. A keyboard 21 as a code input means provided with a registration closing key or the like for declaring the end of the customer's purchase product registration;
A display 22 for displaying the total amount of the customer, etc., and a printer 23 for performing receipt printing and journal printing are mounted.
18.

Further, there is provided a drawer 24 for storing a change reserve, cash paid by a customer, and the like. An opening command signal from the I / O port 19 is sent to a drawer opening device 25 for automatically opening the drawer 24. It is sent out.

In the RAM 13, as shown in FIG.
Attribute code-based totalizer 31, which is provided with attribute code, attribute name data, amount data and point data area correspondingly, product code of sales registered product, sales floor code,
A registered product buffer 32 for temporarily storing product data 41 including attribute codes, name data, data on the number of digits, status data, etc., a transaction buffer 33 for storing sales transition data of each product registered for sale, Various memory areas such as an offline table 34 for storing the product data 41 are formed.

Here, the attribute code and the attribute name data corresponding to the attribute code in the totalizer 31 for each attribute code are set in advance by a DLL (down line loading) process from the store processor 2. Note that the attribute code “0099” is used as sales data of other products.

The CPU 11 is controlled by a program preset in the ROM 12 or the like so as to process the sales registration of the merchandise purchased in accordance with the flowchart shown in FIG.

That is, the CPU 11 monitors a key signal from the keyboard 21 as ST (step) 1,
The product code, sales floor code,
When the quantity (input can be omitted in the case of one point) and the price are input, it is determined that the customer-purchased product is registered, and the process proceeds to ST2.

In ST2, the line state between the POS terminal 1 and the store processor 2 is determined from the state of the input signal to the communication interface 15 (line determination means).

Then, in the case of a line connection state, so-called in-line, an inquiry message is created using the commodity code and the sales floor code entered as keys in ST3 as search keys,
This inquiry message is transmitted to the communication interface 15 and the transmission path 3
To the store processor 2 through This allows
In the store processor 2, the product file 4 is searched by the search key in the inquiry message, and the product data 41 including the corresponding product code, sales floor code, attribute code, name data, money number limit data, status data, and the like.
Is transmitted as a response message, the response message is received via the communication interface 15 (inquiry processing means).

Thus, if a response message can be received,
Stores the product data received as ST4 in the registered product buffer 3
Write to 2.

Next, as ST5, the offline table 34 is searched for the product code in the registered product buffer 32, and it is determined whether or not the product data 41 of the same product code is stored (data determining means).

If not stored, ST6
Is NO, the product data 41 in the registered product buffer 34 is added to the offline table 34 in ST7 (product data adding means).

On the other hand, if stored, ST
The determination in step 6 becomes YES, and the product data of the same code in the offline table 34 is compared with the product data in the registered product buffer in ST8. If a part of the status data or the like does not match, in ST9, the product data of the same code in the offline table 34 is replaced with the product data in the registered product buffer (product data updating means).

If the product data of the same code in the offline table 34 completely matches the product data in the registered product buffer, the process of ST9 is not performed.

Thereafter, as ST10, the merchandise sales registration process is executed based on the merchandise data in the registered merchandise buffer 32 (in-line registration processing means).

More specifically, if the status data has an automatic discount section, the price entered by the key is discounted with the automatic discount data to obtain the sales amount. If the tax category is a foreign tax, the tax amount is obtained from the price and the tax rate.

When discount data of a customer purchase item is inputted by a key operation on the keyboard, the discount permission flag is checked in the status data. If the discount is permitted, the discount processing is executed. If the discount is prohibited, the discount data is inputted. Error. Similarly, when the discount data of the customer purchased product is inputted by key operation, the discount flag is checked in the status data, and if the discount is permitted, the discount processing is executed; if the discount is prohibited, the discount data is executed. Make the input an error.

In this way, if the sales data and the sales data of the customer purchased products are acquired based on the product data in the registered product buffer 32 and the input data from the keyboard, the sales data is totaled by the attribute code. Registration processing for each attribute code in the device 31. Further, the transaction buffer 33 stores sales transaction data including a product code, a sales floor code, the number of sales points, and an amount of the customer purchased product.
To accumulate.

With the above, the sales registration work for one customer purchased product at the time of in-line is completed.

On the other hand, when the line is disconnected in ST2, that is, when the device is off-line, the offline table 34 is searched with the product code entered in ST11 to determine whether or not the product data 41 of the same product code is stored. (Table search means).

Here, if stored, ST12
Is YES, the product data corresponding to the same product code in the offline table 34 is written to the registered product buffer 32 as ST13. After that, the above ST10
In the same manner as the processing of (1), the commodity sales registration processing is executed based on the commodity data in the registered commodity buffer 32 (offline registration processing means).

If the product data of the same product code as the input product code is not stored in the offline table 34, the determination in ST12 is NO, and the product code and the sales floor code entered by key in ST14 and the attribute code “0099” and the name data “GP9” of the attribute code “0099” read from the attribute code-specific totalizer 31
"9" is written into the registered product buffer 32 as product data. In this case, "Limit on the number of digits"
Each data of "status" is "0".

After the product data in the registered product buffer 32 is added or updated in the offline table 34 in the same manner as in the above-described ST6 to ST9, the same as in the above-described ST10, the data in the registered product buffer 32 is stored in the registered product buffer 32. The product sales registration process is executed based on the product data.

Thus, the sales registration for one customer-purchased product at the time of the off-line is completed.

In the POS terminal 1 of the present embodiment configured as described above, the product code of the product to be sold, the sales floor code, the number, When a price or the like is input, an inquiry is made to the store processor 2 using the product code and the sales floor code as search keys. Then, when the product data of the selling product is received as the response data, the sales data of the selling product is registered based on the product data.

At this time, the offline table 34 is searched to determine whether or not merchandise data having the same code as the received merchandise data is stored. If not stored, the received product data is added to the offline table 34. On the other hand, if it is stored, the content of the product data corresponding to the same code is updated to the content of the received product data.

Accordingly, the latest product data of each sales product registered at the time of in-line is stored in the offline table 34.

In this state, if the line state with the store processor 2 is not connected, that is, so-called off-line, the store processor 2 cannot be inquired even if a sales product is registered by inputting a product code or the like.

In this case, the offline table 34 is searched using the input product code as a search key.
When a code corresponding to the search key is detected, the product data corresponding to the code is the product data of the corresponding sales product received from the store processor 2 at the time of in-line, so the sales data of the sales product is registered based on the product data. I do.

If a code matching the search key cannot be detected in the off-line table 34, the sales data is classified as an attribute code "0099" and sales data is registered.

Therefore, even if the product is registered at least once at the time of in-line even if it changes from in-line to off-line, the sales of the sales product based on the product data estimated to be answered from the store processor 2 at the time of in-line Since the data is registered, it is possible to execute the sales data registration processing of sales products that is almost as accurate as in the case of in-line.

Since the storage capacity of the offline table 34 is limited, for example, up to 600 items of product data can be stored, and date / time data is added to the item of product data to add or update the product data. The date / time data read from the clock circuit 14 is set at this time, and when the storage capacity of the offline table 34 is full or close to that, a function of deleting a predetermined number of item data from the offline table 34 in order of date / time data is provided. It is convenient to provide.

The code input means is not limited to a keyboard, but may be a scanner or the like.

[0060]

As described above in detail, according to the present invention, when a code of a product for sale is input at the time of in-line, an inquiry is made to a host device using the code as a search key, and product data of the product for sale is received as response data. Then, based on the product data, the sales data of the sales product is registered and the offline table is searched. If the product data of the same code as the received product data is not stored, the received product data is added to the offline table. If it has been stored, the content of the product data corresponding to the same code is updated to the content of the received product data. Also, when the code of the product for sale is entered offline, the offline table is searched using the code as a search key, and when a code that matches the search key is detected, the sales data of the product for sale based on the product data corresponding to the code is searched. Is registered.

Accordingly, it is possible to provide a merchandise sales registration data processing device capable of executing the same accurate sales data registration processing of sales merchandise as at the time of in-line even if the line status with the host device changes from in-line to off-line.
