Description

TECHNICAL FIELD The present invention relates to a product sales data processing device such as an electronic cash register or an electronic toll scale for registering product sales data.

[Prior Art] For example, in a conventional face-to-face electronic charge balance, an operator weighs a product purchased by a customer at a balance section, and a product number attached to the product is keyed in from a keyboard. Then, the unit price per unit weight set in advance corresponding to the product number is read, the price is calculated from the unit price and the measured value, and the total is added to the totalizer. Then, each time the closing key is instructed to end one transaction, the sales commodity detailed data in the transaction and the total amount of money in the totalizer are printed on a receipt or label and issued, and then the totalizer is set to “0”. It is designed to be cleared.

In such an electronic fee scale, as a discounting method for the sales amount or the total amount of goods, a plurality of discount keys are provided on the keyboard, and different discount rates are preset to these discount keys. When any one of the discount keys is operated after registration of the merchandise or calculation of the total price, discount calculation is performed on the sales price or total price of the registered merchandise at the discount rate set in the input key. There is a way to do it.

In addition, the discount classification information is stored for each product, the discount rate corresponding to each discount classification information is set, and the discount classification information of the registered product is retrieved every time the product is registered, and the corresponding discount rate is set. There is also a method of taking out and calculating the discount. (Jpn. Pat. Appln. KOKAI No. 60-135989) [Problems to be solved by the invention] However, although the former method has an advantage that the discount rate of discounted products can be arbitrarily changed by selecting a discount key,
The key operation was required each time, and the operability was poor. Further, the discount rate that can be selected is limited depending on the number of discount keys, and when it is desired to use another discount rate, the setting content of the discount rate corresponding to the discount key must be changed, which is complicated.

On the other hand, in the latter method, the discount process is automatically performed by the registration operation of the discounted product, so the operability is good, but the discount rate of the discounted product is fixed by the setting data, and it can be arbitrarily changed over time. It was difficult to operate such as changing the discount rate.

Therefore, according to the present invention, by performing a normal product registration operation, it is possible to automatically perform discount processing on the sales amount of the registered product while arbitrarily changing the discount rate according to the passage of time, which makes the operation complicated. It intends to provide a product sales data processing device that can expand the operation of discount services.

[Means for Solving the Problem] A product sales data processing apparatus according to the present invention includes a timekeeping unit that measures a date and time, and a discount rate table for each time zone for setting and storing a discount rate for each time zone of the day, There is provided a discount rate table for each date in which a discount rate is set and stored for each date, and at least two kinds of discount rate tables among a discount rate table for each day in which a discount rate is set and stored for each day of the week, and each product is classified. In the product number file that stores unit price data in advance corresponding to the product number, a table information area for storing table information for identifying each discount rate table for each product number is provided. The unit price data corresponding to the input product number is read by referring to the file, and the table information is stored in the table information area corresponding to the input product number. It is judged whether or not it is set, and if the table information is not set, the sales registration processing of the product sales data is performed with the read unit price data. If the table information is set, it is identified by the table information. From the discount rate table, the discount rate data corresponding to the current date and time measured by the timekeeping unit is acquired,
The product sales data based on the unit price data read with the discount rate data is discounted and then sales registration processing is performed.

[Operation] By taking such a measure, the sales amount of the product registered for sale is automatically discounted at an arbitrary discount rate set in advance for the time zone, the date, or the day of the week. It

Hereinafter, an embodiment in which the present invention is applied to an electronic toll scale will be described with reference to the drawings.

FIG. 2 is a block diagram of an electronic toll balance, in which a CPU (central processing unit) 1 as a control unit main body operates according to a preset program, and a storage unit and a controller unit are connected via a bus line 2. Control. Here, the storage unit includes a ROM 3 in which program data, character generator data, etc. are stored, a RAM 4 including a memory for accumulating product sales data, and a product number in which the product number, product name, unit price, etc. of each product are preset. File 5 is provided.

It should be noted that, in the product number file 5, as shown in FIG. 3, a fixed amount flag (“1” = fixed amount product, corresponding to the product number of each product, which indicates whether the product is a fixed amount product or a metered sale product, Setting area R1 of "0" = merchandise sold), "00" for non-discounted products, "01" for discounted products whose discount rate changes according to the time zone, and discounted rate for different dates A discount flag setting area R2 is set to "10" for a discount target product and "11" for a discount target product whose discount rate changes depending on the day of the week.

On the other hand, the controller unit includes a keyboard controller 7 for input processing of key signals from the keyboard 6, a display controller 9 for driving and controlling the display 8 to display the product name, price, etc., and a printer 10 for printing receipts and the like. The printer controller 11 is provided.

Further, the CPU 1 takes in data of the current date, day of the week, and time from the clock circuit 12 as a timekeeping unit by interruption, and converts the weight signal of the weighing unit 13 for weighing the product into a digital count value. The count data is taken in from the (analog / digital) converter 14 at a predetermined timing.

As shown in FIG. 4, the keyboard 6 has a numeric 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 a subtotal amount. , The current total key 64 for calculating the total amount,
Clear key 65 used for clearing the numbers and clearing errors,
Various keys such as a multiplication key 66 for inputting a multiplier and a cancel key 67 used for immediately preceding cancellation are arranged. 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 stores a numerical buffer 41 for storing numerical data keyed by a numerical key 61.
A totalizer memory 42 that stores the total price of the products sold to one customer, a weight memory 43 that stores the weight value corresponding to the count data loaded from the A / D converter 14, and usually a multiplier "1" is stored. , Multiplier memory 44 for temporarily storing the multiplier if there is a multiplier input with the multiplication key 66, sales registration memory 45 for cumulatively registering sales data of each sold product by product or department, etc. In addition to various memories used in normal registration work, the discount flag "01" is supported, and the hourly table 46 and the discount flag "10" corresponding to the discount rate according to the time of day are set. Correspondingly, a table by date for which a discount rate for one month is arbitrarily set 4
Corresponding to the discount flag “11”, there are provided discount rate setting tables of day-of-week table 48 in which discount rates are arbitrarily set for each day of the week.

Then, the CPU 1 is program-controlled to execute the process shown in FIG. 5 when the product number of the product is input from the keyboard 6 in the registration mode. That is, when the input of the product number is instructed by the key input of the product number key 62, the numerical data in the numeral buffer 41 is recognized as the product number and the product number file 5 is searched. If the corresponding product number is preset in the file 5, the product number data such as the product name, unit price, fixed amount flag, discount flag, etc. is read. Then, first, the fixed amount flag is checked to determine whether the corresponding product is a fixed amount product or a measured sale product. Here, in the case of a flat-rate product, the unit price is multiplied by the multiplier in the multiplier memory 43 to calculate the price, and in the case of a metered-sale product, the unit price is multiplied by the multiplier memory.
The price is calculated by multiplying the weight value in 44.

Next, check the discount flag. Here, the discount flag is "0
In the case of "1", the clock circuit is selected from the discount rate setting table corresponding to the discount flag, that is, the time zone table 46.
The discount rate corresponding to the time zone of the current time read from 12 is taken out, and the discount processing for the above price is executed at the discount rate. On the other hand, when the discount flag is “10”, the discount rate corresponding to the current date read from the clock circuit 12 is retrieved from the discount rate setting table corresponding to the discount flag, that is, the date table 47, and the The discount process for the above price is executed at the discount rate. The discount flag is "11".
In the case of, the discount rate corresponding to the discount flag is retrieved from the discount rate setting table corresponding to the day of the week, that is, the day-of-the-week table 48, and the discount rate for the above price is executed at the discount rate. To do. If the discount flag is "00", it is not a discounted item, so
No discount processing is performed.

After that, in the case of the discount target product, the price after the discount process is registered, and in the case of the non-discount product, 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 out on a receipt or the like, and this processing is ended.

If the product number key-input is not set in the product number file 5, the key input is an error.

In the present embodiment configured as described above, the store side arbitrarily sets the discount rate in advance in each of the discount rate setting tables 46 to 48. That is, the discount rate is freely set in the hourly table 46 corresponding to the discount flag “01” from 0:00 to 23:59 in 1-hour units. In the date-based table 47 corresponding to the discount flag “10”, the discount rate is freely set from 1 day to 31 days. A discount rate is freely set from Sunday to Saturday in the day-by-day table 48 corresponding to the discount flag “11”.

On the other hand, the discount flag is set in advance also in the setting area R2 of the product number file 5. That is, in the case of a non-discounted product, the discount flag "00" is set corresponding to the product number of the product. In the case of a discount target product that adopts a sales method in which the discount rate is changed according to the time of day, the discount flag “01” is set corresponding to the product number of the product. In the case of a discount target product that adopts a sales method in which the discount rate is changed according to the lapse of the date for one month, the discount flag “10” is set corresponding to the product number of the product. In the case of a discount target product that uses a sales method in which the discount rate changes depending on the day of the week, the discount flag “11” is set corresponding to the product number of the product.

By doing so, when the product number of a sale product is keyed in using the keyboard 6 in the registration mode, the product number data (product name, unit price, fixed amount flag,
The discount flag etc.) is read from the product number file 5. If the product is a flat-rate product (flat-rate flag = 1), the unit price in the product number data is multiplied by the multiplier in the multiplier memory 44 to calculate the price. The multiplier in the multiplier memory 44 is
If a multiplier has been input with the numeric key 61 and the multiplication key 66 prior to inputting the product number, the multiplier is the multiplier, and if not, it is "1". On the other hand, when the merchandise is a merchandise sold (fixed amount flag = 0), the price is calculated by multiplying the unit price in the product number data by the weight value in the weight memory 43. The weight memory 43 always stores the weight value corresponding to the count data periodically fetched from the A / D converter 14, that is, the weight value of the product weighed by the weighing unit 13.

Next, the discount flag in the product number data is determined. And when the discount flag is "01", the time zone table
The discount rate corresponding to the current time zone is retrieved from 46,
A discount process for the above price is executed at the discount rate.
That is, for products whose discount flag is set to "01", the discount rate changes depending on the time of sale registration, and the discount processing is performed.

On the other hand, when the discount flag is "10", the discount rate corresponding to today's date is fetched from the date table 47, and the discount processing for the price is executed at the discount rate. That is, for products whose discount flag is set to "10", the discount rate changes depending on the date when the product is registered for sale, and discount processing is performed.

When the discount flag is "11", the discount rate corresponding to today's day of the week is fetched from the day-of-week table 48, and the discount processing for the price is executed at the discount rate. That is, for products whose discount flag is set to "11", the discount rate changes depending on the day of the week when the product is registered for sale, and the discount process is performed.

If the discount flag is "00", no discount processing is performed on the product.

As described above, according to this embodiment, the discount rate setting tables 46 to 48 are created in advance, and the area of the product number file 5 is set.
By setting an arbitrary discount flag in R2, it becomes possible to sell the product at a discount rate with a different discount rate according to the lapse of time with a simple operation of inputting the product number of the sold product. Therefore, the discount rate of discounted products is
It becomes possible to realize a sales method in which the sales are changed by date or day of the week without any special key operation, and it is possible to promote sales without lowering work efficiency. Also, it becomes possible to distinguish between changing the discount rate according to the time of day, changing the discount rate according to the date, and changing the discount rate according to the day of the week, which has the advantage that various selling methods can be easily realized. .

The present invention is not limited to the above embodiment. For example, in the above embodiment, the case where the discount rate is changed for each time zone, each date, and each day of the week has been described, but it is sufficient that the discount rate has at least two functions. Further, the present invention is not limited to the electronic charge balance, and it is needless to say that the present invention can be applied to an electronic cash register and a POS (point of sale information management) system in which the cash register is centrally managed by a host computer. That's a good thing. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, the discount selling method in which the discount rate changes according to the passage of time of the day and the discount selling method in which the discount rate changes according to the date or the day of the week. Even if and are mixed, if the registered product is a discount target product, the sales amount of the registered product is discounted at the discount rate corresponding to the registration date and time of the discount sales method applicable to that product, just by performing the normal product registration operation. It is possible to provide a product sales data processing device that can perform discount calculation and can expand the operation of a discount service without making the operation complicated.
