Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a product sales data processing device in which, for example, a plurality of electronic price scales are connected in-line to a host computer via a transmission line.

[Prior Art] For example, an electronic price scale equipped with a weighing section, a keyboard, a display, a printer, etc. has a product number file in an internal memory in which a unit price, single product name, etc. are preset in correspondence with the product number of each product. Then, when the product number of the product to be sold is inputted from the keyboard, the unit price and name of the product are read out from the product number file. In this state, when weighing is performed at the scale section, the price is calculated from the weight value and unit price, and the product name and small value 1 weight value are displayed on the display.

In addition to displaying the price, the product name, unit price, weight, price, etc. are printed on the label paper by the printer, and the label is issued.

Incidentally, in recent years, scale systems in which multiple electronic fare scales are connected in-line to a host computer via a transmission line and each electronic fare scale is centrally managed by the host computer have become popular in stores with large sales areas and multiple scales. It's being used. In this scale system, the (It value data setting) of each product in the product number file provided in each electronic price scale.

Changes were made sequentially, one by one, by the host computer.

[Problem to be Solved by the Invention] However, in the above-mentioned scale system, if the unit price of an arbitrary product changes during store opening operations due to a discount service during a time period, for example, the host computer changes the product number file in each electronic price scale. The unit price data corresponding to the product is changed, but at this time, the unit price data is changed one by one, so there are scales with different unit price data within the same time period. For this reason, even though multiple customers purchased the same product at the same time, there was a risk that the unit price would differ depending on the scale used to process the sale.

Therefore, the present invention provides a system in which a host controller centrally manages a plurality of sales processing terminals having product files in which unit prices, etc. are set corresponding to product codes. To provide a product sales data processing device that can prohibit sales processing in a terminal until the unit price change is completed, and can prevent the same product from being sold at different unit prices within the same time period.

[Means for Solving the Problems] The present invention centrally manages, using a controller, a plurality of sales processing terminals each having a product file in which at least a unit price is set corresponding to each product code. , a code notification means for notifying the code of the product whose unit price should be changed to each terminal via a transmission line when the unit price data of the product file in each terminal is changed, and after the code is notified by this notification means and after the corresponding product is changed. A modified unit price transmission means is provided to transmit unit price data to each terminal via a transmission line, and each terminal stores a sales processing prohibition flag corresponding to the code of each product set in its own product file. a prohibition flag setting means for setting a sales processing prohibition flag corresponding to the corresponding product in the prohibition flag memory when the code of the product whose unit price should be changed is notified via the transmission line; unit price change processing means for changing the unit price of the corresponding product in the product file upon receiving changed unit price data; prohibition flag canceling means for canceling the sales processing prohibition flag corresponding to the product whose unit price has been changed by the processing means; and code input. A sales processing prohibition means is provided which checks a sales processing prohibition flag corresponding to the corresponding product in the prohibition flag memory when the code of a sales product is input by the means, and prohibits sales processing for the corresponding product if the flag is set. This is a product sales data processing device.

[Operation] In a product sales data processing device that takes such measures, when a unit price change occurs, the controller notifies each terminal of the code of the product whose unit price should be changed. In response, each terminal sets a sales processing prohibition flag corresponding to the product with the notification code. Thereafter, unit price change data for the corresponding product is sent from the controller. Then, in each terminal device, the unit price data corresponding to the corresponding product in its own product file is changed, and the corresponding sales processing prohibition flag is canceled.

On the other hand, when the code of a sales product is input using the code input means in each terminal device, the state of the corresponding sales processing prohibition flag is checked, and if that flag is set, the product is the one whose unit price will be changed from now on. Therefore, sales processing is prohibited. Therefore, it is guaranteed that the unit prices of products sold at each terminal within the same time period are the same.

[Example] Hereinafter, an example in which the present invention is applied to the scale system will be described with reference to the drawings.

FIG. 1 is a conceptual diagram of a scale system, in which n (n is plural) electronic fare scales 1a, lb, . . . 1n and one host computer 2 are connected in-line via a transmission line 3. There is. Here, each of the electronic fare scales 1a to 1n functions as a terminal for sales processing, and the host computer 2 functions as a higher-level controller for centrally managing each terminal.

FIG. 2 is a block diagram of the electronic fare scales 1a to 1n, and the six scales have the same configuration. C as the main body of the control unit
A PU (central processing unit) 11 controls the following memory section and controller section via a pass line 12.

The memory section is a ROM (read/write) that stores control program data, character generator data, etc.
only memory) 13, RAM (random access memory) 1 that forms various memories for data processing
4. Product information such as the product name and 41 price per unit weight is preset corresponding to the product number as a code for each product, and a product number file 15 is provided for accumulating sales amounts and the like for each product. The controller section takes in key signals from a keyboard 16 on which various function keys such as keys for inputting product numbers are arranged, and sends them to the CPU.
1, a display controller 19 that drives and controls a display 18 for displaying product name, unit price, weight value, price, etc., and a printer 20 that prints on the label paper being transported and issues labels. A printer controller 21 that drives and controls the printer controller 2, and a transmission controller 22 that controls data transmission and reception performed with the host computer 2 via the transmission line 3 are provided.

Further, the CPU II is adapted to take in date and time data from the clock circuit 23 at a timely manner. Furthermore, a count value (weight value) is read at a predetermined timing from an A/D (analog/digital) converter 25 that converts the weight signal measured by the scale unit 24 into a digital count value. .

FIG. 3 is a configuration diagram of the product number file 15. As shown in the figure, the product number file 15 provided for each electronic price scale 18 to 1n includes a product number area Ml, a product name area M2,
A unit price area M3, a prohibition flag area M4, a total sales area M5, etc. are formed. Product information such as product name and unit price is preset corresponding to the product number of each product.

Further, sales information such as sales amount is accumulated for each product. The prohibition flag in the prohibition flag area M4 is CPUI, 1.
It is set to "1" when prohibiting the sales process of the corresponding product by program control by rOJ.
It will be canceled on.

If it becomes necessary to change the unit price data set in the unit price area M3 of each product number file 15, the host computer 3 operates according to the procedure shown in FIG. That is, 1 is sent to each electronic fare scale 1a to 1n via the transmission line 3.
An 11-value change command is sent to notify that a small value change will be made. Next, a product number usage prohibition command is edited based on the product number of the one product whose valence should be changed, and similarly sent to the six scales 1a to 1n (code notification means).

After the transmission, the changed unit price data of the corresponding product is similarly transmitted to the six scales 1a to 1n (changed unit price transmission means). In this way, the corresponding product number prohibition commands and changed unit price data are transmitted for all products whose unit prices should be changed, and when the transmission is completed, unit price change end commands are sent to 6 scales 1a to 1.
Send to n and end.

On the other hand, the CPU II of each electronic fare scale 1a to 1n is
It is program-controlled to execute the processing shown in FIG. That is, as ST (step) 1, the transmission controller 22 determines whether data transmitted from the host computer 2 is being received. If no key signal has been received, the keyboard controller 17 determines whether or not the key signal input from the keyboard 16 is being received as Sr1. If the data has not been imported, the process returns to STI.

When data is received by STI, the type of data is checked. If the received data is a unit price change command, a unit price change flag is set to "1" in the RAM 14. If the received data is a product number prohibition command and the above unit price change flag is set, set the prohibition flag corresponding to the corresponding product number in the own product number file 15.
1” (M stop flag setting means). If the received data is 11i price data after the change and the prohibition flag for the corresponding product number is set, the contents of the unit price area M3 corresponding to the corresponding product number in the own product number file 15 are changed to the 11i price data after the change.
Change to 1 value (jli value change processing means).

Further, the prohibition flag corresponding to the corresponding product number in its own product number file 15 is reset to "0" (prohibition flag release means). If the received data is a tli value change command, RA
The unit price change flag of M14 is canceled and set to "0".

When a key signal is taken in at Sr1, the type of input key is checked from the key signal. If the input key is a product number input key, product data such as product name, unit price, and prohibition flag corresponding to the input product number is read from the own product number file 15°.

Then, the read prohibition flag is determined. Here, if the prohibition flag is unset rOJ, normal sales processing is performed. That is, the read product name and unit price are displayed on the display 18. Next, the count value is taken in from the A/D converter 25 and converted to a weight value, a price is calculated from the unit price and the weight value, and the weight value and price are displayed on the display 18. Thereafter, when issuing a label is instructed, the printer 20 is driven to print out the product name, unit price, weight, price, etc. on label paper, and issue the label. On the other hand, if the prohibition flag is set, the above-described sales process is not performed and the key input is treated as an error (sales process prohibition means).

In this embodiment configured in this way, for example, if it becomes necessary to change the unit price of minced pork with product number [0001] from 200 yen to 150 yen due to a discount service during store opening operations, the host computer 2 Platform scale 1a~1
After sending the unit price change command for n, the product number [0001
] is sent. Accordingly, the product number [00011
The prohibition flag corresponding to is set to "1". As a result, sales processing of [minced pork] is temporarily prohibited on the platform scales 1a to 1n.

After that, from the host computer 2 to the platform scales 1a to 1n, the changed unit price data of [minced pork] [150 yen]
is sent. Accordingly, the contents of the unit price area M3 corresponding to the product number [0001F in the product number file 15 of each of the scales 1a to 1n are sequentially changed to 150 yen. Then, in the scale whose unit price has been changed, the prohibition flag corresponding to product number [0001] is reset to "0". As a result, on the scale after the unit price change, [minced pork] will be sold at a unit price of 150 yen. On the other hand, in the scale where the unit price has not been changed yet, the prohibition flag corresponding to product number [0001] is set in rlJ, so the sales process of [minced pork] is prohibited.

As described above, according to this embodiment, each electronic fare scale 18 to 1n
In each product number file 15, an area M4 is provided for storing a prohibition flag corresponding to the product number of each product,
The host computer 2 connected inline via the transmission line 3 sets a prohibition flag for the product whose unit price is to be changed to prohibit sales processing of the product, and when the unit price change is completed, the corresponding prohibition flag is set. Since the cancellation is made to permit the sales processing of the corresponding product, the sales processing of the product whose unit price should be changed will be performed only on the scale for which the unit price change has been completed. In other words, if the unit price of a product whose unit price is to be changed is not yet changed on a scale, the sales process for that product is not performed. Therefore, the problem of selling the same product at different unit prices (unit price before change and unit price after change) using different scales within the same time period is eliminated.

In the above embodiment, the products set in the product number files 15 provided for the six scales 1a to 1n may be different for each scale. In this case, when the CPU 1 of the 6 scales 1a to 1n receives the product number use prohibition command from the host computer 2, it searches its own product number file 15, and if the corresponding product number does not exist, it ignores the command. Become. In addition, in the above embodiment, when there are multiple products whose unit prices should be changed, the product number usage command and changed unit price data are sent one by one for each product, but first, the product number usage commands for all the products whose unit prices should be changed are sent 6 units. Then, the corresponding changed unit price data may be sequentially transmitted to the six scales.

It goes without saying that the present invention can also be applied to a cash register system in which a controller centrally manages a plurality of electronic cash registers each having a product file.

[Effects of the Invention] As described in detail above, according to the present invention, a plurality of sales processing terminals that store product files in which 111 values, etc. are set corresponding to product codes, are controlled by a host controller. Product sales data in a centrally managed system that can prohibit the sales processing of products whose unit price should be changed at each terminal until the unit price change is completed, and prevent the problem of the same product being sold at different unit prices within the same time period. Processing equipment can be provided.
