Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a product sales data processing device that performs single item registration.

C. Prior Art] Conventionally, this type of device has a product code, for example, PLU.
(Price Look Up) By inputting a code, the unit price corresponding to that PLU code is read from the single item file and registered, and if a PLU code to be linked is set corresponding to that PLtJ code, reads the unit price from the single item file for the PLU code that should be linked, performs the single item registration process, and roughly calculates the PLU that should be linked for this PLtJ code as well.
If a code is set, the unit price for the PLLI code to be linked will also be read from the single item file and processed for single item registration.If you specify the first PLU code and register, the product with that PLU code will be registered. It is known that other products sold in combination are also registered using link PLU codes. In this conventional device, unit prices are set in single item files for all products sold in combination.

[Problem to be solved by the invention] However, in a system where unit prices are set for all products that are sold in combination, for example, if you want to change the price of some products depending on the service period or service period, it is necessary to change the price of some products in the single product file. When the unit price of a product is changed and the period or time has elapsed, the unit price of the single item file must be changed again, which poses a problem that changing the price becomes extremely troublesome.

This invention was made in order to solve such problems, and it is an invention in which, by registering one product, other products for which combination sales with that product are set in advance are automatically registered. An object of the present invention is to provide a product sales data processing device in which some of the products cannot be registered without externally inputting the unit price, thereby making it possible to easily change the price of the product.

[Means for Solving the Problems] As shown in FIG. 1, the present invention inputs a product code assigned to each product from the input means a, and calculates the unit price corresponding to the product code from the single product file b. For those that read and perform single item registration processing, a link setting area C is provided in the single item file b for setting data that determines whether there is a product code to be linked corresponding to each product code, and the set unit price is opened. A flag area d is provided to set a status flag that determines whether or not to When data is set in the link setting area C of the corresponding single item file b, the corresponding product code must be read from the link table e using that data, and the unit price open status flag must be set in the flag area d based on the product code. For example, the unit price is retrieved from the single item file b and processed for single item registration, and if the unit price open status flag is set in the flag area d, when the amount data is input from the amount data input means f, that amount is registered for the single item. ! l! A registration processing means 9 is provided for processing.

[Operation] In the present invention having such a configuration, when a product code is input, the unit price corresponding to the product code is read out from the single item file b and registration processing is performed.

Also, if there is data in the link setting area C corresponding to the product code of the single item file b, the product code corresponding to that data is read from the link table e, and if unit price open is not set in the flag area d of the single item file b. The unit price corresponding to that product code is stored in the single item file B.
Read from and process the registration. Further, if unit price open is set in the flag area d of the single item file b, the amount data for that product code is input and registration processing is performed. Therefore, for products whose prices are subject to change, the unit price may be set to open.

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

FIG. 2 is an external view of the device of this embodiment, which is composed of a single electronic cash register.

This electronic cash register is provided with a keyboard 2, a display section 3, a receipt issuing port 4, and a drawer 5 on the front surface of a housing 1. Further, a customer display section 6 is rotatably supported at the upper part of the housing 1.

As shown in Fig. 3, the keyboard 2 has 8 number keys 11 for inputting numerical data such as codes and amounts, a department key 12 for specifying the department of the product when registering the department, and a single item code. A PLU key 13 used to input a certain PLIJ code, an amount key 14 used to input an amount, a discount key 15 used for discounting, a discount key 16, a premium key 17, and a total. A subtotal key 18 used to calculate the amount, a deposit/cash total key 19 used to close the registration, etc. are provided. The keyboard 2 is also provided with three control switches 20 for turning on and off the power and for switching and setting the business mode to "registration", "accounting", etc.

"Registration" refers to tasks such as registering product sales data in memory and issuing receipts, and "payment"
This refers to tasks such as printing out the registered and accumulated data.

FIG. 4 is a block diagram showing the circuit configuration of the electronic cash register. Reference numeral 21 is a CPU constituting the main body of the control unit. RO that performs processing and stores fixed data such as programs for each of the above-mentioned services via the address bus 22, data bus 23, and control line 24;
It controls M25 and a RAM 26 provided with a memory for registering product sales data.

A drawer control circuit 2 for opening the drawer 5 is connected to the CPU 21 via a data bus 23 and a control line 24.
7. A keyboard input circuit 28 that takes in and controls key signals from the keyboard 2, a switch input circuit 29 that takes in and controls switch signals from the control switch 20, and a display control circuit that controls the display of each display section 3.6 based on display data. 30 and a printer IlltE circuit 32 that controls a dot printer 31 that prints on receipt paper and journal paper based on print data.

The RAM 26 stores a single item file 2 as shown in FIG.
61, departmental cumulative memory 262, link table 263
, number buffer 264, PLU code save area 265
, a link PLU processing counter 266, a link PLIJ processing flag F1, an amount key enforcement flag F2, etc. are provided. The single item file 261 has a PLU code area m1 in which a large number of PLU codes are set, and
Corresponding to each PLU code in the PLU code area ml, a name area m2 where a name is set, a flag area m3 where a status flag is set, a link department area m4 where a department code to be linked is set, and a PLU to be linked.
A link setting area m5 is provided to set a link table that determines the presence or absence of a code, a unit price area m5 is where the unit price of the product is set, and a total area m7 is provided to accumulate the number of sales items and sales amount.

The departmental cumulative total memory 262 is configured to cumulatively total the number of sales items and sales amount for each set department. The link table 263 sets a PLU code to be linked in accordance with the link table number.

The CPU 21 performs various registration tasks when the control switch 20 is set to the "registration" mode and the keyboard 2 is powered by the keys.
When the PLU code is set at 1 and the PLU key 13 is pressed, the key processing shown in FIG. 6 is performed.

To do this, first, before operating the PLU key 13, it is checked whether there is a numeric input in the numeric buffer 264, and it is also checked whether the amount key compulsion flag F2 is set. If there is no numeric input or if the amount key compulsion flag F2 is set, an error process is performed. Further, if a number has been input in advance and the amount key enforcement flag F2 is in a reset state, the same PLU code is searched from the PLU code area m1 of the single item file 261 based on the input PLLI code. At this time, the applicable PLIJ
If there is no code, it is determined that an incorrect code has been entered and an error process is performed.

If there is a corresponding PLU code, it is then checked whether a link table Na is set in the link setting area ms. If link table ~0 is not set, it is determined that there is no link PLtJ, and link PLtJ is
The contents of the processing counter 266 are set to "0". Also, if link table Na is set, link PLU processing flag F1 is set, and link PLU! 2! Logical counter 2
Add "+1" to 66.

Next, normal PLU processing is performed, that is, the unit price is read from the unit price area m6, the name is read from the name area m2,
Based on these, the data is edited for display and printing, and the display data is output to the display control circuit 30 and the print data is output to the printer control circuit 32. Further, the unit price and the number of points are accumulated in the accumulation area m7.

When this processing is completed, it is then checked whether the link PLLI processing flag F1 is set, and if this flag is not set, this key processing is ended.

Also, if this flag is set, the PLU to link
It is determined that there is a link PLU, and then the link PLU registration process is performed.

First, the contents of the link PLU processing counter 266 are "
Check whether it is 10 or less. If the value is not "10 or less", this key processing ends. This is to prevent the number of linked PLtJs from exceeding 10. If the content of the counter 266 is r10 or less, the PLU code to be linked is read from the link table 263 using the link table Nα set in the link setting area ms, and the corresponding PLU code is extracted from the single item file 261 based on the PLtJ code. Search. Then, it is checked whether a unit price open status flag is set in the flag area m3 corresponding to the PLtJ code. Then, if the unit price open status flag is not set, the linked PLtJ code is set in the number buffer 264,
After the PLU code is set to the same state as that entered from the keyboard 2, the same PLU key processing as described above is performed. Therefore, registration processing will also be performed for this linked PLtJ code.

If the unit price open status flag is set, the PLLJ code is set in the PLU code save area 265, the amount key compulsion flag F2 is set, and this key processing is ended.

After the amount key compulsion flag F2 is set, all keys manually operated other than the amount key 14 and the number key 11 are turned into errors. When the amount key 14 is operated, an error occurs unless amount data is previously input using the number keys 11. Therefore, after the price key compulsion flag F2 is set, the user must input the price using the number key 11 and operate the price key 14, and the open unit price is forced to be set. When the amount key 14 is operated and amount data is inputted, the amount key compulsion flag F2 is reset. And from then on, department key 12, PL
Manual operation of keys such as the U key 13, the subtotal key 18, and the deposit/cash total key 19 is now permitted.

In this embodiment with such a configuration, for example, if products with PLtJ codes rl 23J, r50J r70Jr250J are to be sold by linking, the single item file 261 and the link table 263 have status flags and links, respectively, as shown in FIG. Table N (11PLLI
A code will be set.

Therefore, when you enter rl 23J with the number key 11 and operate the PLU key 13, the unit price rlooo yen of PLU code rl 23J is read out and registered, and then PLt
Link table NarO corresponding to J code r123J
The PLU code “50” linked by 1J is read from the link table 263. And this PLtJ
With the code "50", the unit price "123 yen" is read out from the unit price area m6 of the single item file 261 and is registered.

This time, link table Na r O2J is set, so PLU code "70" is entered from link table 263.
is read out. Then, from the single item file 261, the unit price “
50 yen" is read out and registered.

This time, link table 1m r03J is set, so PLU code r250J is entered from link table 263.
is read out. And in the single item file 261, P
Since the unit price open flag "1" is set in the status flag corresponding to the LtJ code r250J, automatic registration by unit price is not performed and the system waits for input of the amount from the keyboard 2.

However, in this state, by entering r780J with the numeric key and operating the amount key 14, the PLU code r250
Product J will be registered as having a unit price of "780 yen." When the registration process based on the open unit price ends, a series of link registration processes based on the P'LU code rl 23J ends.

If the deposit/account key 19 is operated in this state, this registration is closed and the dot printer 31 issues a receipt as shown in FIG.

In this way, the unit price for products with the PLtl code r250j can be made open, so when selling multiple products in combination, the prices of some products can be changed freely, and the service period and service time can be changed freely. It is easy to change the price of a product by determining the price.

In addition, in the above embodiment, the PL whose unit price is preset
Although a case has been described in which a PLIJ with an open unit price is registered as a link by registering U, this is not necessarily the case, and the reverse may be possible. Further, there may be a plurality of PLUs with unit price open in one combination.

Although the above embodiments have described the invention applied to a single electronic cash register, the present invention is not necessarily limited to this, and can also be applied to a PoS system that uses a cash register as a terminal and centrally controls it. It is applicable.

[Effects of the Invention] As detailed above, according to the present invention, in an apparatus in which registration of one product automatically registers other products for which combination sales with that product are set in advance, Some of the products cannot be registered unless the unit price is externally input, thereby providing a product sales data processing device that can easily change the price of the product.
