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 for inputting a merchandise code assigned to each merchandise to register sales data of the sold merchandise.

[0002]

2. Description of the Related Art Generally, a PO controller in which a plurality of electronic cash registers are centrally managed by a host controller.
In an S (point-of-sale information management) system, a controller is provided with a product information file in which product information such as a product name, a unit price, and a department code to be linked is preset in correspondence with a product code assigned to each product. An input unit such as a keyboard and a scanner for inputting a product code to the electronic cash register is provided. When the product code is input from the input unit, each electronic cash register inquires the controller of product information corresponding to the product code. Thereby, when the corresponding product information is returned from the controller, the sales data of the corresponding product is registered based on the product information.

[0003] In such a POS system, conventionally, when registering a product to be sold at a discount, a discount amount or a discount rate is entered by a key each time a product code of the discount product is entered in an electronic cash register. There is a method in which a unit price is calculated by a discount, a normal unit price and a discount unit price can be preset in a product information file in advance, and a sales registration process is performed on a discounted product at a discount unit price.

[0004] However, in the former method, a discount amount or a discount rate must be entered by key each time a discounted product is registered, and the registration operation is complicated. On the other hand, in the latter method, a normal unit price and a discount unit price must be preset for each discounted product, and there is a problem that the setting operation is troublesome.

For example, Japanese Patent Application Laid-Open No. 58-146965 discloses a unit price data input unit for inputting unit price data of each product, a section code input unit for inputting a department code for classifying each product, and Discount data setting means for setting data necessary for discount for each department to be classified and discount command means for instructing discount are provided. In response to the discount command by the command means, a discount corresponding to the input department code is provided. An electronic cash register is disclosed which calculates discounted price data from data and input unit price data and outputs the discounted price data.

With such an electronic cash register, there is no need to enter a discount amount, a discount rate, and the like at the time of registration of a discounted product, so that the registration operation is not complicated, and all of the discounted products are registered. It is not necessary to preset the discount information necessary for the setting, so that the setting operation is easy.

[0007]

However, according to the above publication, when registering a product for sale, the product must be registered with a department code for classifying the product, so that the POS system that manages the sales of each product individually is required. Was not applicable.

[0008] Therefore, the present invention relates to a system for managing the sales of each product individually, which is excellent in operability when registering discounted products and can simplify the work of setting product information for discounted products. It is intended to provide a data processing device.

[0009]

According to the present invention, a product information storage unit for storing product information such as a unit price and a classification code to be linked corresponding to a product code of each product and a classification code for classifying each product are provided. A discount information storage unit for selectively storing discount information, a product code input unit for inputting a product code attached to a sales product, and product information when a product code is input by the product code input unit. A merchandise information reading means for reading merchandise information corresponding to the input merchandise code from the storage unit, and searching the discount information storage unit with a classification code in the merchandise information read by the reading means, and discounting the classification code; Discount information discriminating means for discriminating whether or not information is set; and when the discriminating means discriminates that there is discount information, the corresponding merchandise sales data is discounted according to the discount information to calculate a sales increase. A merchandise sales data processing apparatus that includes a discount registration processing means for processing.

[0010]

In the merchandise sales data processing device having such a configuration, merchandise information such as a unit price and a classification code to be linked is set in the merchandise information storage unit in advance corresponding to the merchandise code of each merchandise. In addition, discount information is selectively set in the discount information storage unit in correspondence with each classification code for classifying each product.

[0011] When registering a product for sale, the product code of the product for sale is input by the product code input means. Then, the merchandise information corresponding to the input merchandise code is read from the merchandise information storage section, and the discount information storage section is searched for the classification code in the read merchandise information, and the discount information is set for the classification code. Is determined. When it is determined that there is discount information, the corresponding merchandise sales data is discounted according to the discount information and sales registration processing is performed.

Therefore, since the merchandise code is input when registering the merchandise, it is possible to manage the sales individually. In this case, when registering the discounted product, the registration operation is not particularly complicated because the product code is merely input as in the case of the product sold normally. In addition, since the discount information is set for each classification code for classifying each product, the setting operation is simpler than when setting the discount information for each discount product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a POS system will be described below with reference to the drawings.

FIG. 1 is an overall view of a POS system.
A plurality of POS terminals (TM) 1 composed of electronic cash registers and one file processor (FP) 2 composed of a host computer are connected in-line via a transmission line 3.

As shown in FIG. 2, the file processor 2 stores in advance a class code and a department code to which the product is linked, and product information such as a product name and a unit price of the product corresponding to the product code of each product. In addition to a product information file 4 as a product information storage unit for setting and storing, a product sales file 5 for cumulatively processing sales of each product by product code, a class sales file 6 for cumulative processing by class code linking sales of each product, A department sales file 7 is provided which performs cumulative processing for each department code linking the sales of each product.

Incidentally, the product code is a code assigned to specify each product, the class code is a code assigned to classify each product in detail, and the section code is a general code for each product. This is a code assigned for classification.

FIG. 3 is a block diagram showing the configuration of the POS terminal 1. Reference numeral 11 denotes a control unit main body.
It is a PU (Central Processing Unit). The CPU 11 has a built-in arithmetic circuit, a memory control circuit, and the like, executes various arithmetic processes based on input data, and stores program data and the like for the CPU 11 to control each unit via the bus line 12. A ROM (read only memory) 13 and a RAM (random access memory) 14 in which various memory areas used for data processing in the CPU 11 are formed are operated.

A communication interface 15 for controlling transmission and reception of data to and from the file processor 2 via the transmission path 3, a keyboard controller 17 to which a key signal from a keyboard 16 is input, a display 1
A display controller 19 for driving and controlling the printer 8 to display characters and the like corresponding to the display data, and a printer controller 2 for driving and controlling the printer 20 to perform receipt printing and the like.
1 and an I / O port 22 are connected to the CPU 11 via the bus line 12.

The I / O port 22 has a power on /
A signal from a mode switch 23 for controlling various operations modes such as “registration”, “payment”, and “setting” and a signal from a barcode scanner 24 for reading a barcode are input. Further, an opening drive signal is output to a drawer 25 for storing cash or the like.

The keyboard 16 is provided with various keys required for executing the above-described tasks, such as a numeric key, a code key, a subtotal key, a squeezing key, and a clear key. Here, the product code of each product can be key-input by inputting the combination of the numeric key and the code key. Also,
Some of the products are printed as barcodes or affixed as barcode labels, and for such products, the barcode can be input by reading the barcode with the barcode scanner 24. That is, the keyboard 16 and the barcode scanner 24 function as product code input means for inputting a product code attached to a product for sale.

As shown in FIG. 4, the RAM 14 stores a registered merchandise buffer 31 for storing sales data of merchandise sold and registered in one transaction, and total data of merchandise registered in one transaction. A totalizer 32 for storing, a class discount table 33 for storing a discount rate corresponding to an arbitrary class code, a department discount table 34 for storing a discount rate corresponding to an arbitrary department code, and the like are formed.

Here, the class discount table 33 and the section discount table 34 constitute a discount information storage unit for selectively storing discount information corresponding to a classification code for classifying each product.

The setting of the data in the discount tables 33 and 34 is performed by sequentially inputting a class code or a department code and a discount rate from a keyboard (not shown) of the file processor 2 into a memory, and writing the contents into the memory. -It is done by line loading.

Thus, the CPU 11 is programmed so as to execute the commodity registration process shown in FIG. 5 in a state where the "registration" mode is selected by the mode switch 23.

That is, when a product code of a product for sale is input via the bar coat scanner 24 or the keyboard 16 as ST (step) 1, an inquiry message of product information corresponding to the product code is created, and An inquiry message is transmitted to the file processor 2 via the communication interface 15.

Upon receiving the inquiry message, the file processor 2 searches the product information file 4 and finds a link class code corresponding to the input product code,
Since it is configured to read out the product information such as the link section code, name, unit price, etc. and return it to the POS terminal 1 that has made the inquiry (product information reading means), ST2
If there is a response of the commodity information, the class discount table 33 is searched with the link class code in the commodity information (ST3) (ST3).

If the same class code as the link class code is set in the class discount table 33, it is determined that the class discount has been established, and the corresponding discount rate is read from the class discount table 33. And
The discount amount is calculated by multiplying the unit price in the product information by the discount rate, and the discount amount is subtracted from the unit price to calculate the sales amount after the discount. After that, input product code, link class code,
The merchandise sales data including the link section code, the sales amount after the discount, the number of sales, and the like are stored in the registered merchandise buffer 31 (discount registration processing means). Further, the sales amount is added to the totalizer 32. Further, the product name, the sales price, the number of sales, and the like are displayed on the display 18 and printed out on a receipt or the like by the printer 20, and the process is terminated.

If it is determined in ST3 that the class discount is not established, that is, if the same class code as the link class code is not set in the class discount table 33, the link section in the product information returned as ST4. The department discount table 34 is searched by the code (discount information determining means).

If the same section code as the link section code is set in the section discount table 34, it is determined that the section discount has been established, and the corresponding discount rate is read from the section discount table 34. Then, the discount amount is calculated by multiplying the unit price in the product information by the discount rate, and the sales amount after the discount is calculated by subtracting the discount amount from the unit price. After that, as in the case of the class discount establishment, the merchandise sales data including the input merchandise code, the link class code, the link department code, the sales amount after discount, the number of sales points, and the like are stored in the registered product buffer 31 (discount registration). (Processing means) Further, the sales amount is added to the totalizer 32, and the display of the product name, the sales amount, the number of sales, etc., and the printing process are performed, and this process is completed.

If it is determined in ST4 that the department discount is also not established, that is, if the same department code as the link department code is not set in the department discount table 34, it is a sales registration of a normally sold product. The unit price in the responded product information is set as the sales price. Then, the merchandise sales data including the input merchandise code, the link class code, the link section code, the sales amount, the number of sales, and the like are stored in the registered merchandise buffer 31. Further, the sales amount is added to the totalizer 32, and the display of the product name, the sales amount, the number of sales, etc., and the printing process are performed, and the process is terminated.

Incidentally, the merchandise sales data for one transaction stored in the registered merchandise buffer 31 is transmitted to the file processor 2 via the communication interface 15 in response to the input of the closing key. In the file processor 2, every time the product sales data is received, the product code. It is configured to accumulate the sales amount and sales points for each link class code and link section code.

In the present embodiment having such a configuration, a class code and a department code to be linked together with a product code, a product name, a unit price, and the like of each product are preset in the product information file 4 in the file processor 2, and the product sales file is stored. 5, the sales of each product are managed by the single item, the class, and the section by the class sales file 6 and the section sales file 7, respectively.

On the other hand, merchandise discounts are made in class units or department units. That is, merchandise belonging to the same class or the same section is discounted at a fixed discount rate. Here, the discount information for each class or each department is registered in the file processor 2 and is set by down-line loading in the class discount table 33 or the department discount table 34 of each POS terminal 1. .

For example, it is assumed that the discount information shown in FIG. 4 is set in each of the POS terminals 1 in the class discount table 33 and the department discount table 34. In this state, when the product code of the product belonging to the class code [01] is input from the barcode scanner 24 or the keyboard 16 and registered for sale, the file name, unit price, and link class code [01] of the product are transmitted from the file processor 2. And product information such as a link section code. And
Since the discount rate [5%] is set in the class discount table 33 in correspondence with the class code [01], the unit price of the product is multiplied by the discount rate to calculate a discount, and the discount is calculated from the unit price. Is reduced to calculate the sales price after the discount. Then, based on the sales amount after the discount, the sales of the corresponding product are registered for each individual product, each class, and each department.

The product code of the product belonging to the section code [1] is stored in the barcode scanner 24 or the keyboard 1.
When the information is entered and registered for sale, product information such as the product name, unit price, link class code and link section code [1] of the product is read from the file processor 2.
Then, since the discount rate [5%] is set in the department discount table 34 corresponding to the department code [1], the discount rate is calculated by multiplying the unit price of the product by the discount rate, and the discount rate is calculated from the unit price. The discount amount is reduced, and the sales amount after the discount is calculated. Then, based on the sales amount after the discount, the sales of the corresponding product are registered for each individual product, each class, and each department.

In this case, it is assumed that no discount information is set in the class discount table 33 for the class code to which the corresponding product is linked. In other words, even if a product is linked to a department for which discount information is set in the department discount table 34, if the discount information of the class code linked to the product is set in the class code discount table 33, , Discount processing corresponding to the class code is preferentially performed.

As described above, according to the present embodiment, even though the sales of the sold products are managed individually by the product sales file 5, when the discounted products are registered, the discounted products are registered in the same manner as the normally sold products. The registration operation is not particularly complicated because only the product code is input. In addition, since the discount information is set in units of class codes or department codes for classifying each product, the setting operation is simplified and efficient as compared with a case where discount information is set for each discount product.

In the above-described embodiment, when discount information is set in both the class code and the department code to be linked, the discount information of the class code is preferentially discounted. The discount processing of the code may be prioritized and the discount processing may be performed. Further, even if the classification code is one kind or three kinds or more, it is possible to achieve the same operation and effect as the present invention. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention, such as applying the present invention to a single electronic cash register.

[0039]

As described above in detail, according to the present invention, although the sales of each product can be managed individually, the operability when registering the discounted product is excellent, and the sales of the discounted product can be improved. It is possible to provide a merchandise sales data processing device that can simplify the operation of setting merchandise information.
