Description

Description: TECHNICAL FIELD The present invention relates to a product sales data processing device such as a single electronic cash register or a POS system that performs link registration processing for a plurality of products.

[Prior Art] Conventionally, as a device of this type, by inputting a product code, for example, a PLU (price look up) code, a unit price corresponding to the PLU code is read out from a single product file and registration processing is performed. When the PLU code to be linked is set corresponding to the code, the unit price is also read from the single item file for the PLU code to be linked, the single item registration processing is performed, and the PLU code to be linked also for this PLU code is set. If it is set, the unit price will be read from the single item file for the PLU code to be linked and the single item registration processing will be performed. If you register by specifying the first one PLU code, it will be combined with the product of that PLU code. It is known that other products to be sold are also registered by the link PLU code.

[Problems to be Solved by the Invention] However, in such a conventional device, when a discount or a discount is added to a product to be sold in combination, a discount, a discount, or an additional charge is added after PLU registration. There was a problem that the key operation had to be performed and the key operation was troublesome.

The present invention has been made to solve such a problem, and when a plurality of products are linked and registered, and then the registration result is dealt with such as discount, discount, and surcharge, the transaction is performed. An object of the present invention is to provide a product sales data processing device that can be automatically performed and can be simplified in operation.

[Means for Solving Problems] The present invention, as shown in FIG. 1, inputs the product code attached to each product from the input means a to obtain the unit price corresponding to the product code from the single product file b. In the case of reading out and performing single item registration processing, the link destination code corresponding to the product code to be linked corresponding to each link table number and the specific transaction code for performing specific transaction processing such as discount, discount, and surcharge And a link setting area c in which a link table number for setting the link destination code of the link table d and a link table number for specifying a specific transaction code are provided. The corresponding product code or the link destination code read from the link table d corresponds to the corresponding link of the single item file b. Setting area c
A code reading means for reading the link destination code or the specific transaction code from the link table d according to the link table number read from the link table number; and when the link destination code is read by the code reading means, When the specific transaction code is read by the code reading means and unit e for reading the unit price from the single item file b and the code reading unit, a predetermined transaction process is performed based on the read specific transaction code. And means for terminating the link registration process.

[Operation] In the present invention having such a configuration, when the product code is input, the unit price corresponding to the product code is read from the single product file b and the registration processing is performed. Also, a single file b
If there is a link table number that specifies the link destination code in the link setting area c corresponding to the product code, the link destination code corresponding to the link table number is read from the link table d, and the unit price corresponding to the link destination code is read. It is read from the single item file b and is registered. Further, the next link table number corresponding to the link destination code is read from the single item file b and the link destination code or the specific transaction code is read from the link table d. Then, when the specific transaction code is read from the link table d by the link table number read from the single item file b, a predetermined transaction processing based on the specific transaction code is performed, and a series of link registration processing is ended. For example, a discount key, a discount key, a surcharge key, etc. are automatically processed and the link registration process is terminated.

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

FIG. 2 is an external view of the apparatus of this embodiment, and this embodiment is composed of a single electronic cash register. This electronic cash register is provided with a keyboard 2, a display unit 3, a receipt issuing port 4, and a drawer 5 on the front surface of a housing 1. A customer display unit 6 is rotatably supported on the top of the housing 1.

As shown in FIG. 3, the keyboard 2 is provided with a numeric key 11 for inputting numerical data such as a code and an amount of money, a department key 12 for specifying the department of a product when registering the product, and a single product code. PLU key 13 used to enter a certain PLU code, amount key 14 used to enter an amount, discount key 15 used when discounting,
Discount key 16 used for discounting, surcharge key 17 used for surcharge, subtotal key 18 used for calculating total amount, deposit / cash total key 19 used for closing registration, etc. Is provided. Further, the keyboard 2 is provided with a key-type control switch 20 for controlling the power on / off and switching the work mode to “registration”, “payment” or the like. Note that "registration" is a task of registering product sales data in a memory and issuing a receipt, and "clearing" is a task of printing out the accumulated and registered data.

FIG. 4 is a block diagram showing a circuit configuration of the electronic cash register, and 21 is a CPU constituting the control unit main body.
21 has a built-in arithmetic circuit, etc., performs various arithmetic processing based on the input information from the keyboard 2 and an address bus.
A ROM 25 for storing fixed data such as the programs of the above-mentioned business and a RAM 26 provided with a memory for registering product sales data are controlled via 22, a data bus 23 and a control line 24.

Further, the CPU 21 takes in a drawer control circuit 27 for opening the drawer 5 via a data bus 23 and a control line 24, a keyboard input circuit 28 for taking in and controlling a key signal from the keyboard 2, and a switch signal for a control switch 20. A switch input circuit 29 for controlling, a display control circuit 30 for controlling display of the respective display portions 3 and 6 based on display data, and a printer for controlling a dot printer 31 for printing on receipt paper and journal paper based on print data. Control circuit
32 are connected respectively.

In the RAM 26, as shown in FIG. 5, a single item file 261, a departmental cumulative memory 262, a link table 263, and a number buffer.
264, PLU code save area 265, link PLU processing counter
266, a link PLU processing flag F ₁ , an amount key compulsory flag F _{2 and the} like are provided. The single file 261 contains multiple PLUs.
While providing a PLU code area m ₁ with a code set, corresponding to each PLU code in the PLU code area m ₁ ,
Named area m ₂ for setting name, flag area m ₃ for setting status flag, link section area m ₄ for setting section code to link, link table No. for setting PLU code to be linked Setting area m
_5, is provided with a unit price area m ₆ as well as the total area m ₇ to total sales number and sales amount of money you set the unit price of the product.

The department-based cumulative memory 262 accumulates the number of sales and the amount of sales for each set department. In the link table 263, for example, a discount processing code and a discount processing code are set together with the PLU code linked in correspondence with the link table No.

The CPU 21 performs various registration work processing when there is a key input on the keyboard 2 when the "registration" mode is set by the control switch 20.
When the code is entered and the PLU key 13 is pressed, the sixth
The key processing shown in the figure is performed.

First, it is checked whether or not there is a numeral input in the numeral buffer 264 before the key operation of the PLU key 13, and whether the amount key compulsory flag F ₂ is set. If there is no input of a numeric value or if the amount key compulsory flag F ₂ is set, an error is processed. If there is a number input in advance and the amount key compulsory flag F ₂ is in the reset state, the PLU of the single item file 261 is based on the PLU code that was input.
Search for the same PLU code in code area m ₁ . At this time, if there is no corresponding PLU code, it is determined that an incorrect code has been input and error processing is performed.

If there is a corresponding PLU code, then the link setting area m ₅
Check whether the link table No. is set in. If the link table No. is not set, it is determined that there is no link PLU and the link PLU processing counter 26
Set the content of 6 to "0". If the link table number is set, the link PLU processing flag F ₁ is set and the link PLU processing counter 266 is incremented by "+1".

Then, a normal PLU process, that is, the unit price is read out from the unit price area m ₆ , the name is read out from the name area m ₂ , and the display data is edited for display and printing based on these, and the display data is output to the display control circuit 30. At the same time, the print data is output to the printer control circuit 32. In addition, the unit price and points are accumulated area m ₇
Total to.

When this process ends, it is checked whether or not the link PLU process flag F ₁ is set, and if this flag is not set, this key process ends. If this flag is set, it is determined that there is a PLU to be linked, and then the link PLU registration processing is performed.

This first checks whether or not the content of the link PLU processing counter 266 is "10 or less". If it is not "10 or less", this key processing is terminated. This is to prevent the number of linked PLUs from exceeding 10. If the content of the counter 266 is "10 or less", the code to be linked from the link table 263 is read out by the link table No. set in the link setting area m ₅ (code reading means), and if the code is a PLU code. Applicable PL from single file 261 based on the PLU code
Search for U code. Then, it is checked whether a unit price open status flag is set in the flag area m ₃ corresponding to the PLU code. If the unit price open status flag is not set, the linked PLU code is set in the numeral buffer 264, and the same PLU code as that input from the keyboard 2 is set, and then the same PLU key processing is performed. Therefore, the registration process is also performed for the linked PLU code. (Means for Single Item Registration Processing) If the unit price open status flag is set, the PLU code is set in the PLU code save area 265, the amount key compulsory flag F ₂ is set, and this key processing ends.

After the monetary key compulsory flag F ₂ is set, the monetary key
All key inputs except 14 and numeric key 11 will cause an error. If the amount key 14 is operated, an error occurs if the amount data is not input by the numeric key 11 in advance. Therefore, after the amount key compulsory flag F ₂ is set, the numeric key 11
It becomes a state in which the amount of money must be entered and the amount of money key 14 must be operated, and the open unit price is forcedly set. When the amount key 14 is operated and the amount data is input, the amount key compulsory flag F ₂ is reset.
After that, key input of the department key 12, the PLU key 13, the subtotal key 18, the deposit / cash total key 19 and the like is permitted.

If the code read from the link table 263 is, for example, a discounting code, the discounting process is automatically performed based on a preset discount amount, and the key process is terminated. (Means for terminating the link registration process) The amount of the discounted amount is displayed and printed. If the code is a discount processing code, the discount processing is automatically performed based on a preset discount rate, and the key processing is terminated. The discounted amount is displayed and printed.

In the present embodiment having such a configuration, for example, when selling and linking the products of PLU codes “123”, “50”, “70” and “250” and discounting them, the single item file 261 and the link table 263. A status flag, a link table No., a PLU code, and a discount code are set in each field as shown in FIG.

Therefore, when the numeric keypad 11 is used to enter "123" and the PLU key 13 is operated, the unit price "100 yen" of the PLU code "123" is first read and registered, and then the PLU code "123" is associated. The PLU code “50” linked by the link table No. “01” is read from the link table 263. Then, the unit price “120 yen” is read out from the unit price area m ₆ of the single item file 261 by the PLU code “50” and registered.
Since the link table No. “02” is set this time, the PLU code “70” is read from the link table 263. Then, the unit price "50 yen" is read from the single item file 261 and registered.

Since the link table No. “03” is set this time, the PLU code “250” is read from the link table 263. And with this PLU code "250", a single file 26
The unit price "780 yen" is read from 1 and registered. Since the link table No. “04” is set this time, the code for the discount processing is read from the link table 263. Then, the discount process is performed with the discount amount preset by this code, for example, "20 yen".

In this way, PLU codes “123”, “50”, “70”, “250”
It is possible to automatically register the combination of each of the products, and to automatically perform the discount processing for it. That is, the key operation for the discounting process is unnecessary, and the key operation can be simplified.

If the deposit / cash total key 19 is operated in this state, the registration is closed and the receipt shown in FIG. 7 is issued by the dot printer 31.

When discounting is performed in the link registration in which the discount code is not set in the link table 263, the discount processing may be performed by operating the numeric key 11 and the discount key 15 as usual.

In addition, although the above-mentioned embodiment has described the one in which the present invention is applied to a single electronic cash register, the present invention is not necessarily limited to this, and may be applied to a POS system which uses a cash register as a terminal device and controls it centrally. It is applicable.

[Effects of the Invention] As described in detail above, according to the present invention, when a plurality of products are linked and registered, and then a transaction such as a discount, a discount, or a surcharge is performed on the registration result, the transaction is automatically performed. It is possible to provide a merchandise sales data processing device that can be performed in a simple manner and can be simplified in operation.
