Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register or an electronic fare scale that performs a registration process of product sales data.

[Prior Art] For example, in a conventional face-to-face electronic price scale, an operator weighs a product purchased by a customer at a weighing section and manually enters the product number assigned to the product from a keyboard. Then, the unit price per unit weight set in advance in correspondence with the product number is read out, the price is calculated from the unit price and the measured value, and the price is accumulated in the totalizer.

Each time the closing key is used to instruct the end of a transaction, the sales product details data for that transaction and the total amount in the totalizer are printed on a receipt or label, and then the totalizer is set to ``0''. ” to be cleared.

In such an electronic price scale, a plurality of discount keys are provided on the keyboard and different discount rates are preset to each of the discount keys as a method of discounting the sales amount or total amount of the product. After registering the product or calculating the total amount, select one of the above discount keys.
There is a method in which when a key is input, a discount is calculated on the sales amount or total amount of the registered product using a discount rate set in the input key.

In addition, discount classification information is stored for each product, and
Set the discount rate corresponding to each discount category information,
There is also a method of extracting the discount classification information of the registered product each time the product is registered, and extracting the corresponding discount rate to calculate the discount. (Utility Model Application Publication No. 135989/1989) [Problems to be Solved by the Invention] However, although the former method has the advantage of being able to arbitrarily change the discount rate of discounted products depending on the selection of the discount key, it is not necessary to operate the key each time. was required, resulting in poor operability. Also,
The selectable discount rates are limited depending on the number of discount keys, and if you want to use another discount rate, you have to change the settings of the discount rate corresponding to the discount key, which is cumbersome.

On the other hand, in the latter method, the discount is automatically processed by registering the discounted product, so it is easy to operate, but the discount rate of the discounted product is fixed by the setting data, and it can be changed arbitrarily as time passes. Operations such as changing the discount rate were difficult.

Therefore, by performing a normal product registration operation, the present invention can automatically process a discount on the sales amount or total amount of the registered product while arbitrarily changing the discount rate as time passes, making the operation less complicated. The present invention aims to provide a product sales data processing device that can expand the operation of discount services without causing problems.

[Means for Solving the Problems] The product sales data processing device of the present invention includes a table in which a discount rate is set by time zone, a table in which a discount rate is set by date, and a table in which a discount rate is set by day of the week. At least one table is provided, and the sales amount or total amount of products registered for sale is discounted using the applicable discount rate of the table according to the registration conditions.

[Function] By taking such measures, the sales amount or total amount of products registered for sale will be automatically discounted at any discount rate set in advance for the time period, date, or day of the week. will be discounted.

[Embodiment 1] Hereinafter, an embodiment in which the present invention is applied to an electronic fare scale will be described with reference to the drawings.

FIG. 2 is a block configuration diagram of an electronic fare scale, in which a CPU (central processing unit) 1 as the main body of the control unit operates according to a preset program, and controls the storage unit and the controller unit via a pass line 2. Control. Here, the storage unit includes a ROM3 in which program data, character generator data, etc. are stored, a RAM4 equipped with a memory for cumulatively registering product sales data, and a product number in which the product name, unit price, etc. of each product are preset. File 5 is provided.

In addition, as shown in Fig. 3, the product number file 5 has the following information:
Setting area R1 for the fixed price flag (rlJ = fixed price product, "0" = product sold by weight), which indicates whether the product is a fixed price product or a product sold by weight, corresponding to the product number of each product, and when the product is not eligible for discount. ``00'', ``01'' when the discount rate changes depending on the time of day, ``10'' when the discount rate changes depending on the date, and ``10'' when the discount rate changes depending on the day of the week. A discount flag setting area R2 is provided, which is set to "11" when the product is a discount target product.

On the other hand, the controller section includes a keyboard controller 7 that inputs and processes key signals from the keyboard 6, a display controller 9 that drives and controls the display 8 to display product names, prices, etc., and a printer 0 that prints on receipts and the like. A printer controller 1 is provided.

In addition, the CPU inputs the current date, day of the week, and time data from the clock circuit 12 by interrupt, and also uses an A/D (analog/digital ) Count data is taken in from the converter 14 at a predetermined timing.

As shown in FIG. 4, the keyboard 6 includes a number key 61 for inputting numerical data, a product number key 62 for indicating that the numerical data is a product number, and a subtotal key 63 for calculating subtotals. , various keys such as a current key 64 for calculating the total amount, a clear key 65 used for clearing numbers, canceling errors, etc., a multiplication key 66 for inputting a multiplier, and a cancel key 67 used for last-minute cancellation, etc. is installed. Here, the current total key 64 functions as a closing key for instructing the end of one transaction.

As shown in FIG. 1, the RAM 4 includes a number buffer 41 for storing numerical data entered manually using the number keys 61, a totalizer memory 42 for storing the total price of products sold to -1 customers, Weight memory 43 that stores weight values corresponding to count data taken in from the A/D converter 14
, a multiplier memory 44 that normally stores a multiplier of "1" and temporarily stores the multiplier when a multiplier is input using the multiplication key 66; Sales registration memory 4 for sales aggregation
5 etc. In addition to various types of memory used in normal registration work,
A time zone table 46 in which a discount rate is arbitrarily set for each time of the day in correspondence with the discount flag "01", and a discount rate is arbitrarily set for each day of the month in correspondence with the discount flag "10". Discount rate setting tables are provided, including a date-specific table 47 and a day-of-the-week table 48 in which discount rates are arbitrarily set for each day of the week in correspondence with the discount flag "11."

The CPU is program-controlled to execute the process shown in FIG. 5 when the product number is input from the keyboard 6 in the registration mode. That is, when input of a product number is instructed by manual input of the product number key 62, the numerical data in the number buffer 41 is recognized as the product number, and the product number file 5 is searched. And the same file 5
If the corresponding product number has been preset, the corresponding product number data such as the product name, unit price, fixed price flag, discount flag, etc. are read out. First, the fixed price flag is checked to determine whether the corresponding product is a fixed price product or a product sold by weight. here,
In the case of a fixed price product, the price is calculated by multiplying the unit price by the multiplier in the multiplier memory 43, and in the case of a product sold by weight, the price is calculated by multiplying the unit price by the weight value in the multiplier memory 44.

Next, check the discount flag. Here, the discount flag is “01
'', the discount rate corresponding to the time zone of the current time read from the clock circuit 12 is retrieved from the discount rate setting table corresponding to the discount flag, that is, the time zone table 46, and the discount rate corresponding to the time zone of the current time read from the clock circuit 12 is obtained. Execute discount processing. On the other hand, when the discount flag is "10", the discount rate corresponding to today's date read from the clock circuit 12 is extracted from the discount rate setting table corresponding to the discount flag, that is, the date-specific table 47, and the discount rate corresponding to today's date read from the clock circuit 12 is extracted. Execute discount processing on the above price using the discount rate. Further, when the discount flag is "11", the discount rate corresponding to the current day of the week read from the clock circuit 12 is extracted from the discount rate setting table corresponding to the discount flag, that is, the day-of-week table 48, and the discount Execute discount processing on the above price at the rate. Note that if the discount flag is "00", the product is not eligible for discount, so no discount processing is performed.

After that, if the product is eligible for discount, the price after discount processing,
If the product is not eligible for discount, the normal price is registered in the sales registration memory 45 and added to the totalizer memory 42. Further, the product name, price, etc. are displayed on the display 8, and the printer 10 is driven to print them out on a receipt or the like, and this processing is completed.

Note that if the product number entered manually by the key is not set in the product number file 5, the manual entry of the key is treated as an error.

In this embodiment configured in this manner, the store arbitrarily sets the discount rate for each of the discount rate setting tables 46 to 48 in advance. That is, discount rates are freely set in the time zone table 46 corresponding to the discount flag "01" from 0:00 to 23:59 in one hour units. The date table 47 corresponding to the discount flag "10" has 1 to 1
You can freely set the discount rate on a daily basis up to the 31st. In the day-of-week table 48 corresponding to the discount flag "11", discount rates are freely set from Sunday to Saturday for each day of the week.

On the other hand, a discount flag is also set in advance in the setting area R2 of the product number file 5. That is, in the case of a product that is not eligible for discount, a discount flag "OO" is set corresponding to the product number of the product. In the case of a discount target product that uses a sales method that changes the discount rate according to the passage of time in a day, a discount flag "01" is set corresponding to the product number. In the case of a discount target product that uses a sales method that changes the discount rate according to the passage of one month (=1), a discount flag "]0" is set corresponding to the product number.

In the case of a discount target product whose sales method is such that the discount rate changes depending on the day of the week, a discount flag "11" is set corresponding to the product number of the product.

By doing this, the keyboard 6 in registration mode
When you manually enter the product number of a sales product using the key, the product number data (product name) corresponding to the input product number.

unit price, fixed price flag, discount flag, etc.) are read from the product number file 5. Here, if the product is a fixed price product (fixed price flag -1), the unit price in the product number data is added to the multiplier memory 4.
The price is calculated by multiplying by the multiplier within 4. Note that the multiplier in the multiplier memory 44 is stored in the number key 6 before entering the product number manually.
If a multiplier has been input using 1 and the multiplication key 66, this is the multiplier, and if it has not been input, it is "1". On the other hand, if the product is sold by weight (fixed price flag = 0), the price is calculated by multiplying the f-11 value in the product number data by the weight value in the weight memory 43. Note that the weight memory 43 always stores the weight value corresponding to the count data periodically taken in from the A/D converter 14, that is, the weight value of the product weighed by the weighing section 13.

Next, the discount flag in the product number data is determined.

If the discount flag is "01", the discount rate corresponding to the time zone of the current time is extracted from the time zone table 46, and the discount process for the price is executed using that discount rate. That is, for products whose discount flag is set to "01", the discount rate will change depending on the time at the time of sales registration, and the discount will be processed.

On the other hand, when the discount flag is "10", the discount rate corresponding to today's day i τj is extracted from the date table 47, and the discount process for the price is executed using that discount rate. That is, for products whose discount flag is set to "10", the discount rate will change depending on the date of sales registration 2, and the discount will be processed.

Further, when the discount flag is "11", the discount rate corresponding to today's day of the week is extracted from the day-of-week table 48,
A discount process is executed on the above price using the discount rate.

That is, for products whose discount flag is set to "]1", the discount rate will change depending on the day of the week at the time of sales registration, and the discount will be processed.

Note that when the discount flag is "00", no discount processing is performed on the product.

As described above, according to this embodiment, by creating each discount rate setting table 46 to 48 in advance and setting an arbitrary discount flag in the area R2 of the product number file 5, the product number for sales products can be manually determined. With a simple operation, you can sell the product at different discount rates over time.

Therefore, it is possible to realize a sales method that changes the discount rate of discounted products by time of day, day of the week, or day of the week without having to perform any special key operations. can be promoted. In addition, it is now possible to distinguish between changing the discount rate depending on the product depending on the time of day, date, or day of the week, which has the advantage of making it easier to implement various sales methods. .

Note that the present invention is not limited to the above embodiments.

For example, in the embodiment described above, the discount rate is changed depending on the time zone, two dates, and the day of the week, but any device having at least one of these functions may be used.

Further, in the above embodiment, the case where discount processing is applied to the price of sold products is shown, but the total amount for each customer is calculated based on the time period.
Discount processing may be performed by changing the discount rate by date or day of the week. Furthermore, it goes without saying that the present invention is not limited to electronic fare scales, but can also be applied to electronic cash registers and POS (point-of-sale) systems in which the cash registers are centrally managed by a host computer. That's a good thing. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, by simply performing a normal product registration operation, the sales amount or total amount of the registered product is automatically adjusted according to the passage of time. To provide a product sales data processing device that can perform discount processing while changing the discount rate and can expand the operation of a discount service without complicating operations.
