Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic cash register used as a standalone device or as a terminal of a POS system.

2. Description of the Related Art Conventionally, retail stores such as supermarkets sometimes offer discounts on specific products as a service to customers.

In addition, at stores that sell food, products that cannot be carried over to the next day, such as perishables, are sold at a discount from about two hours before closing to ensure that there are no leftovers.

In this way, when selling a specific product at a discount, the discount price and the corresponding barcode are printed on a label, and this label is attached to each product in preparation for registration at the electronic cash register. Furthermore, they advertise their discount prices by pasting them inside the store.

In addition, as an electronic cash register used for such discount sales, Japanese Patent Application Laid-Open No. 58-4472
There is something disclosed in the publication No.

This electronic cash register is equipped with a change data memory and a clock circuit that stores the unit price after the change and the time of the change, and the clock data such as the current time from the clock circuit and the change data memory are stored. A comparison is made at predetermined time intervals with the changed time, and when they match, the printer prints out the name of the product whose unit price is to be changed and the unit price after the change.

With this electronic cash register, the cashier can
It is recognized by the printing operation of the printer that it is a discount time period, and sales data registration work is performed based on the printing result.

Furthermore, as an electronic cash register used when conducting similar discount sales, JP-A-62-99893
There is something disclosed in the publication No.

This electronic cash register includes a storage medium that stores the code of the product whose unit price is to be changed, the changed unit price, and its sales data, and a reading/writing means that reads and writes the contents stored in this storage medium. and a keyboard for inputting sales data, etc. If a storage medium is set in the reading/writing means,
After calculating the sales amount using the changed unit price stored in the storage medium, register the sales data in the storage medium itself, and if the storage medium is not set in the reading/writing means. After calculating the sales amount using the normal unit price preset in the price lookup table etc. provided in the device main body, the sales data is stored in the sales data area etc. provided in the device main body memory. This is used to register data.

This electronic cash register stores the code of the product to be sold at a discount and its changed unit price in advance in a storage medium, and reads/writes this storage medium when the discount period arrives.
By setting it in the writing means and changing the unit price of the product, the cashier can register the sales data without being aware of whether the product to be registered is a discount product or not. It is something.

If you affix a label on each product with the unit price for changing the problem that the invention is trying to solve, and then paste a sheet of paper with the discounted price inside the store to advertise it, it takes a lot of time and effort. It hangs,
Unable to respond quickly.

Furthermore, in the case of the electronic cash register disclosed in JP-A No. 58-4472, when registering sales data, it is necessary to input the discount unit price for each product, making the registration operation complicated. It takes a lot of time to do this, and there is also the risk of forgetting to input the changed unit price, causing inconvenience to customers and damaging the store's credibility.

Furthermore, in the case of the electronic cash register disclosed in Japanese Patent Application Laid-Open No. 62-99893, it is necessary to carry out the troublesome work of managing the time at which discounts are given, and the storage means must be read/written at the time when discount sales should start. If you forget to set it in the storage means, the registration process will be performed at the normal unit price, and the same problem as described above will occur.

Furthermore, in either case, the above-mentioned two inventions disclosed in the publication do not take into consideration the display of changed prices to customers. For this reason, it is necessary to carry out advertising work using paper with discount prices written on it.

Means for Solving the Problem The product data storage means has a product data storage means for storing preset product data, and data processing such as changing the price of the product and calculating the sales amount is performed based on the stored contents of the product data storage means. In an electronic cash register, a display device provided near the product, an input device provided near the display device, and change data inputted by the input device stored in the product data storage device. a product data changing means for changing product data; and a changed data output means for outputting and displaying the product data whose price has been changed among the product data stored in the product data storage means to the display device. Established.

The action product data changing means changes the product data stored in the product data storage means based on the change data inputted by the input means, and performs data processing such as calculating the sales amount based on the contents stored in the product data storage means. conduct. Also,
The changed data output means outputs the changed price of the product data stored in the product data storage means to the display device for display. Both the display device and the input means are provided near the product. Therefore, it is possible to flexibly change the product data stored in the product data storage means by inputting change data into the input means while checking the sales status of the product.

Furthermore, the product data whose price has been changed can be displayed on the display device and advertised.

Example An embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, this electronic cash register is formed by connecting a display device 4 to an apparatus main body 1 via a host machine 3 by a connection cable 2 such as an R8232C cable.

As shown in FIG.
A microcomputer is formed by connecting the ROM 6 and the RAM 7 to the U5, and a control key input circuit 8 in which a control key 8 is connected to the CPU 5.
and a keyboard input circuit 9a to which the keyboard 9 is connected.
, a display control circuit 10a to which a display device 10 is connected, a printer control circuit 11a to which a printer 11 is connected, and an in-line interface 12 are connected.

However, as shown in FIG. 3, the keyboard 9 includes the control key 8, a numeric keypad 9b, a department key 9c, a total key 9d, etc.

Further, on the front surface of the display device 4, as shown in FIG.
A keyboard 4e as an input means is provided, which includes a and an end key 4d. This display device 4 is connected to the inline interface 12 of the device main body l via the host machine 3.

Furthermore, as shown in FIGS. 5 to 11, the RAM 7 of the apparatus main body 1 stores a mask table 7a (a mask table 7a) consisting of a product code, its name, its normal unit price, its changed unit price, and a unit price change flag. (see Figure 5), a unit price change data table 7b (see Figure 6) consisting of the product code, its name, and price data corresponding to each of the floating flags 1 to 6 and 11 to 13, and the product code. a floating table 7c (see FIG. 7) consisting of a unit price change time (start time and end time), a floating flag, and a unit price change flag;
A registration buffer 7d (see Figure 8) consisting of the code of the registered product, its quantity, and its price, and a total amount buffer 7e.
(See Figure 9) and total change amount buffer 7f (10th
(see figure) and a communication buffer 7g (see figure 11).

However, the product data storage means is the mask table 7a.
, the unit price change data table 7b, and the floating table 7c.

In addition, the floating flags in the unit price change data table 7b indicate different discount methods, and floating flags 1 to 3 indicate a method of discounting according to the quantity of the purchased product;
Flow flags 4 to 6 indicate a method of discounting unconditionally, and flow flags 11 to 13 indicate a method of discounting depending on the quantity of purchased products only during a specific time period.

Furthermore, a changed unit price (unit price after discount) is set for the price data corresponding to the floating flags 1 and 4.11, a discount amount is set for the price data corresponding to the floating flags 2 and 5.12, and the floating flag A discount rate (the product price is set to 1) is set in the price data corresponding to 3, 6, and 13.

Further, the floating table 7C contains codes of products eligible for discounts and their unit price change times (fluid flags 11 to 1
3) and its flow flag are set in advance.

On the other hand, the host machine 3 also has a mask table 3a (see Fig. 12), a unit price change data table 3b (see Fig. 13), and a flow table 3c (see Fig. 14), as well as the apparatus main body 1. , a communication buffer 3d (see FIG. 15).

In such a configuration, when the control key 4C is set to "SET" and the end key 4d is pressed after the product code and its changed unit price are input using the numeric keypad 4a, the display device 4 displays the screen shown in FIG. As shown in , the input code and change unit price are sent to the host machine 3 as change data.
Send to.

Furthermore, the host machine 3 that received this change data
As shown in Figure 7, the code is searched in the mask table 3a, the received change unit price is set to the change unit price corresponding to the code that matches the received code, and 1 is set to the unit price change flag corresponding to this code. After that, it is determined whether or not the same code as the received code exists in the flow table 3c.

If it is determined that the same code does not exist in the flow table 3C, no processing is performed, and if it is determined that the same code exists, the unit price change flag corresponding to that code is set to 1.

Furthermore, when the above-mentioned processing after determining whether or not a code matching the received code exists in the flow table 3C is completed, change data consisting of this code and the change unit price is transmitted to the main body 1 of the apparatus.

However, the apparatus main body 1 that has received this change data performs the same processing as the host machine on the mask table 7a and the flow table 7C, and corrects each table. Note that the product data changing means consists of the above-mentioned processing after setting the changed unit price shown in FIG.

On the other hand, in the device body 1, when the control key 8 of the keyboard 9 is set to "Register" and the product code and its quantity are input using the numeric keypad 9b to register the product, as shown in FIG. Then, it is determined whether the input data is a product code, and if it is determined that the input data is a product code, the unit price change flag corresponding to that code is set in the mask table 7a. is 1 or not.

If the unit price change flag is determined to be 1, the amount is calculated by multiplying the changed unit price corresponding to that code by the input quantity, and if it is determined that the unit price change flag is not 1, the amount is calculated by multiplying the changed unit price corresponding to that code by the input quantity. The amount is calculated by multiplying the normal unit price and the input quantity.

When the calculation of this amount is completed, it is determined whether or not the same code exists in the registration buffer 7d.

If it is determined that the same code exists in the registration buffer 7d, the quantity and the amount are added to the corresponding area (the part corresponding to the same code) in the registration buffer 7d,
If it is determined that the same code does not exist in the registration buffer 7d, the code, its quantity, and its amount are stored in the registration buffer 7d.
Store it in d.

Furthermore, when the process of storing data in the registration buffer 7d is completed, the code, its product name, its quantity,
After outputting the amount to the printer control circuit 11a and printing a receipt by the printer 11, the same data is output to the display control circuit 10a and displayed on the display 10, and the registration process for one item is completed. .

Furthermore, if there are other products to be registered, the above process is repeated, and in the process of determining whether the input data is a product code, it is determined that the input data is not a product code. If so, it is determined whether the data is due to pressing the subtotal key.

If it is determined that the subtotal key was not pressed, the process moves to other processing, and if it is determined that the subtotal key was pressed, it is determined whether or not there is a code in the registration buffer 7d.

If it is determined that there is a code in the registration buffer, it is determined whether or not the same code as that code exists in the flow table 7c.

The same code as the registered buffer code is in the floating table 7.
c (the unit price change has been set in advance), the unit price change flag corresponding to that code is set to 1 (the changed unit price is set using the keyboard 4e of the display device 4). was carried out).

If it is determined that the unit price change flag is set to 1, it is determined whether the floating flag is one of 1, 4, and 11.

If it is determined that the floating flag is not one of 1.4.11, or if it is determined that the unit price change flag is not set to 1 in the above determination, the floating flag is referred to and the unit price is changed. The amount based on the applicable discount method is calculated from the applicable price data (discount amount or discount rate) in the data table 7b and the data (quantity, amount) in the registration buffer 7d, and this calculation result is added to the total changed amount buffer 7f. and the total amount buffer 7e.

Also, in the above judgment, if it is determined that the same code as the code in the registration buffer is not in the floating table (unit price change is not set), or if the floating flag is one of 1.4.11. If it is determined that
The amount in the registration buffer is added to the total amount buffer 7e.

Furthermore, when the above-mentioned addition process to the total amount buffer 7e is completed, after skipping to the next data in the registration buffer 7d, the above-mentioned process after determining whether or not there is a code in the registration buffer 7d is repeated, and the registration process is repeated. When it is determined that there is no code in the buffer 7d, that is, calculation processing of the amount including discount for all registered products, and
When the summation processing is finished, the contents of the total amount buffer 7e and the contents of the total changed amount buffer 7f are output to the printer control circuit 11a, and the printer 11 outputs the contents of the total amount buffer 7e and the contents of the total changed amount buffer 7f, and the printer 11 adds up the total changed amount (the total amount of the products whose unit prices have been changed). The amount (total payment amount) is printed on the receipt, and the contents of the total amount buffer 7e are output to the display control circuit 10a, the total amount is displayed on the display 10, and the registration process for one item is completed. .

Here, the receipt as a result of printing by the printer 11 when such a registration process is performed is recorded as the 19th receipt.
As shown in the figure.

On the other hand, the host machine repeatedly performs display data transmission processing as a change data output means as shown in FIG. 20 at regular time intervals.

That is, when the process is started, the flow table 3c
Determine whether there is a product code in .

If it is determined that there is a product code in the flow table 3C, it is determined whether or not a flow flag is set corresponding to the code.

If a floating flag is set, the floating flag is one of 11, 12, or 13 (this is a method of giving discounts according to the quantity of purchased products only during a specific time period).
Determine whether or not.

When the flow flag is 11, 12, or 13, the current time measured by a clock circuit (not shown) or the like is the unit price change time set in the flow table 3C, that is, the unit price It is determined whether the start time and end time to be changed are within the range.

If the current time is determined to be within the range between the start time and end time of changing the unit price, or if the floating flag is determined to be neither 11.12.13 in the above determination process includes the product code, its name, and its price data (changed unit price, discount amount, discount rate, etc.)
is stored in the communication buffer 3d.

Furthermore, at the end of the storage process to the communication buffer 3d,
Or, if the above determination process determines that the floating flag is not set, or the above determination process determines that the current time is not within the range between the start time and end time of changing the unit price. In this case, after skipping to the next data in the flow table 3C, the above-described process after determining whether or not there is a product code in the flow table 3C is repeated.

Then, when it is determined that there is no product code in the floating table 3C, that is, when the data extraction for all the products set in the floating table 3C that are subject to price changes has been completed, the communication buffer 3d is The contents are transmitted to the display device 4, and the − display data transmission process is completed.

However, when the content of the communication buffer 3d is transmitted by the host device 3, the display device 4 updates its display when all of the transmitted data is received.

FIG. 21 shows a display screen displayed by the display device 4 when such display data transmission processing is performed.

In this way, it is possible to flexibly change product data by inputting change data into the keyboard 4e while checking the sales status of the product.

Furthermore, the product data whose price has been changed can be displayed on the display device 4 to advertise the product data.

As a result, it is possible to eliminate the labor and time required to create a label with the changed unit price printed on it, attach it to the product, create a paper with the discount price written on it, and paste it in the store. As a result, it becomes possible to quickly offer discount sales to customers.

In addition, even when registering products, there is no need to enter discount unit prices for each product or manage the time at which prices are changed, which simplifies the registration process. At the same time, the unit price change process can be performed reliably.

In this embodiment, the change unit price is set using the keyboard 4e of the display device 4.
In the above, a case has been described in which only the corresponding data for which the flow flag is set among the product data set in advance in the flow table 3c is displayed, but the display is not limited to this, and changes can be made using the keyboard 9 of the device main body 1. Set the unit price, and then use this keyboard 9 or display bag M4.
It is also possible to display the product data for which the changed unit price has been set using the keyboard 4e in addition to the corresponding data for which the flow flag is set among the product data preset in the flow table 3C.

Effects of the Invention As described above, in the present invention, the product data changing means changes the product data stored in the product data storage means based on the change data inputted by the input means, and changes the stored contents of the product data storage means. Data processing such as calculation of sales amount is performed based on the data. Further, the changed data output means outputs the changed price of the product data stored in the product data storage means to the display device for display, and both the display device and the input means are located near the product. It is set in. Therefore, it is possible to flexibly change the product data stored in the product data storage means by inputting change data into the input means while checking the sales status of the product.

Furthermore, the product data whose price has been changed can be displayed on the display device and advertised. As a result, the work of creating a label with the changed unit price printed on it and pasting it on the product, creating a form with the discounted price written on it, and pasting it in the store, and the time and effort required at that time, can be eliminated. As a result, it becomes possible to quickly offer discount sales to customers.

In addition, even when registering products, there is no need to enter discount unit prices for each product or manage the time at which prices are changed, which simplifies the registration process. At the same time, the unit price change process can be performed reliably.
