A flag memory 54 of a registering flag F that is set to "1" during registration of a sale product for one transaction is formed.

Then, C of the charge balance 1 with the MCI / F
The PU 10 is program-controlled so as to process the sales business of the one-by-one sale product, in particular according to the procedure shown in the flowchart of FIG.

That is, as ST (step) 1, the PLU key of the keyboard 14 is used, and the PLU of one sold product is measured.
When the code is input, the PLU file 41 for the merchandise sale product is searched in ST2, and it is determined whether or not the input PLU code is preset. And
If not preset, an error will occur.

If the input PLU code is preset in the PLU file 41 for the merchandise to be sold in ST2, the preset data of the product name and unit price corresponding to the input PLU code is read out in ST3, and the work memory 42 together with the input PLU code is read. PLU code area, product name area and unit price area.

Next, in ST4, if the weight data from the weighing unit 18 is fetched through the weighing unit interface 19, the amount of money (price) is obtained by multiplying the weight data by the unit price data in the work memory 42 in ST5. Is calculated (calculation means). Thereafter, as ST6, the product name data and unit price data in the work memory 42, and the weight data and the price data are displayed on the display unit 16, respectively.

Thereafter, in ST7, the processes of ST4, ST5 and ST6 are repeated until the enter key 14a of the keyboard 14 is operated. Then, if the operation input of the confirm key 14a is detected in ST7, the weight data and the calculated amount data from the balance section 18 at the present time are set in the sales weight area and the sales amount area of the word area 42 in ST8. Further, in ST9, the weight data and the amount data in the work memory 42 are added to the total weight data and the total amount data corresponding to the input PLU code of the PLU file 41 for the measured product, respectively.

Next, in ST10, it is determined whether or not the memory card 3 is mounted on the memory card interface 13, and if not, a message prompting card mounting is issued and the system waits for mounting. And
If the presence of the memory card 3 is detected, ST11
As shown in FIG. 5, the metered sales data composed of the PLU code, the sales weight data, and the sales amount data in the work memory 42 is written in the memory card 3.

Thereafter, in ST12, the CPU waits for the memory card 3 to be removed from the memory card interface 13, and if so, terminates the sales operation for the one-time sale product.

Here, the data writing means is the memory card interface 13 of the MCI / F charge balance 1 and the control section (CPU 10, RO) related to the processing execution of ST11 in FIG.
M11).

On the other hand, the CPU 20 of the POS terminal 2 is
When the "register" mode is selected by the mode switch 34, the program is controlled to execute the processing shown in the flowchart of FIG.

That is, the CPU 20 is always on standby for bar code data input from the bar code scanner 28, card data input from the memory card interface 23, and key data input from the keyboard 26, and when bar code data is input. Scanner input processing is executed, card input processing is executed when card data is input, and key input processing is executed when key data is input.

First, FIG. 7 shows the scanner input process.
This will be described with reference to the flowchart of FIG. When the bar code data is input through the scanner interface 29, the CPU 20 determines in ST21 whether or not the bar code data indicates a PLU code specifying each product.
In the case of the bar code data other than the PLU code, a bar code not directly related to the present invention has been read by the bar code scanner 28, so other processing is executed.

When it is confirmed that the bar code data input in ST21 is a PLU code, the bar code attached to the customer-purchased product is read by the bar code scanner 28, and therefore the flag memory 54 is selected in ST22.
It is determined whether or not the in-registration flag F is set. If not set, it means that the shopper is the first sales registration of the product purchased, so the above registration flag F is set to "1" and the total amount memory 53 is set.
Is cleared to “0”. Flag F already registered in ST22
If is set, the above processing is not performed because it is the second and subsequent sales registrations made by one shopper.

Next, in ST23, the PLU file 51 is searched to determine whether or not the PLU code of the input bar code data is preset. If it is not preset, an error occurs.

If the corresponding PLU code is preset in the PLU file 51 in ST23, ST24
The preset data of the department, product name and unit price corresponding to the PLU code is read out and set together with the PLU code in the PLU code area, department area, product name area and unit price or weight area of the work memory 52.

Next, at ST25, the unit price data in the work memory is multiplied by the score data to calculate the amount of money, and the score data and the amount of money data are used as the work memory 52.
Set each in the sales point area and the sales amount area of. It should be noted that the score data is used as score data when a multiplier is input by the numeric key and the multiplication key immediately before the start of the scanner input process, and when the multiplier is not input, the score data is "1". "Is the score data.

Next, as ST26, the work memory 5 is set.
The point data and the amount data in 2 are the PLU file 51
The product sales data is registered in the storage unit by adding it to the sales point data and the sales amount data corresponding to the corresponding PLU code (registration processing means). Also, S
At T27, the amount data in the work memory 52 is added to the amount data in the total amount memory 53.

Thereafter, in ST28, the product name data and the amount of money data in the work memory 52 are displayed on the display unit 30, and in ST29, the work memory 5 is also used.
When the product name data, unit price data, point data and amount data in 2 are printed on the receipt paper and the journal paper by the printer 32, the current scanner input processing is ended.

The PLU code can be input from the keyboard 26, and when the PLU code is keyed in the "registration" mode, the merchandise sales data registration process is performed in the same manner as the scanner input process.

Next, the card input process will be described with reference to the flowchart of FIG. When the card data is input through the memory card interface 23, the CPU 20 determines in ST31 whether the card data is the metered sale data shown in FIG. Then, in the case of the card data other than the metered sale data, since the data of the memory card which is not directly related to the present invention is input, other processing is executed.

When it is confirmed that the card data input in ST31 is the mass sales data, the MCI /
Since the memory card 3 in which the weighing sale data is written by the data writing means of the F-equipped charge balance 1 is attached to the memory card interface 23, whether or not the registering flag F is set in the flag memory 54 in ST32. To judge. If not set, it means that the shopper is the first sales registration of the product purchased by one shopper, so the above-mentioned registration flag F is set to "1" and the total amount memory 53 is cleared to "0". If the registration flag F has already been set in ST32, the above processing is not performed because it is the second and subsequent sales registrations made by one shopper.

Next, in ST33, the PLU file 51 is searched to determine whether or not the PLU code in the input metered sales data is preset. If it is not preset, an error occurs.

If the corresponding PLU code is preset in the PLU file 51 in ST33, ST34
Then, the preset data of the department and product name corresponding to the PLU code is read out and set together with the PLU code in the PLU code area, department area and product name area of the work memory 52. Further, in the unit price or weight area and the sales amount area of the work area 52, the sales weight data and the sales amount data in the measured sales data read from the memory card 3 are set respectively, and “1” is set in the sales point area. Is set as the score data.

Next, as ST35, the work memory 5 is used.
The point data and the amount data in 2 are the PLU file 51
Is added to the sales point data and the sales amount data corresponding to the corresponding PLU code. Further, in ST36, the amount data in the work memory 52 is added to the amount data in the total amount memory 53.

Thereafter, in ST37, the product name data and the amount of money data in the work memory 52 are displayed on the display 30, and in ST38, the work memory 5 is also displayed.
When the product name data, the weight data and the money amount data in 2 are printed on the receipt paper and the journal paper by the printer 32, the current card input processing is ended.

Here, the data reading means is composed of the memory card interface 23 and the control section (CPU 20, ROM 21) relating to the processing execution of ST31 in FIG. Further, the amount adding means is composed of a control unit (CPU 20, ROM 21) relating to the processing execution of ST36 in FIG.

Next, of the key input processing, especially the closing key 2
The input processing of 6a will be described with reference to the flowchart of FIG. When the CPU 20 takes in the key data via the keyboard interface 27, the CPU 20 determines in ST41 of FIG. 9 whether the key data is the data generated by the key operation of the closing key 26a. And the tightening key 26
When it is confirmed that the data is generated by a key operation other than a, other processing is executed.

When it is confirmed in ST41 that the key data is obtained by operating the tightening key 26a, ST4 is selected.
In step S2, it is determined whether the flag F being registered is set in the flag memory 54. Here, if it is not set, it is an erroneous operation in which one shopper declares the end of registration before the sales registration of the product to be purchased is performed, so an error occurs.

If the registration flag F is set to "1" in ST42, the change amount is calculated by subtracting the total amount data in the total amount memory 53 from the deposit amount data in ST43, and ST44. The change amount is displayed on the display 30. Note that the deposit amount data is the deposit amount data when the number is entered by the number key immediately before the closing key process is started, and the number data is set when the number is not entered. The amount data in the total amount memory 53 is the deposit amount data.

Next, in ST45, if the total amount data, deposit amount data and change amount data are printed on the receipt paper and the journal paper by the printer 32, a receipt cutting command is sent to the printer in ST46 to cut the receipt paper. To issue a receipt. After that, if the opening drive signal is sent to the drawer 35 in ST47 to automatically open the drawer 35, and the registering flag F in the flag memory 54 is reset to "0" in ST48, the current closing key The processing ends (accounting operation processing means).

In this embodiment having such a configuration, a plurality of memory cards 3 are prepared in addition to the MCI / F charge balance 1 at the sales floor where meat is measured and sold.
Then, if the salesperson in charge of the sales floor receives an offer from the customer of the name and quantity of the product he / she desires to purchase, first of all, M
PL provided on the keyboard 14 of the charge balance 1 with CI / F
Operate the U key to enter the PLU code of the product.
Next, the weighing unit 18 weighs the corresponding product. And
After the customer has weighed the requested amount, the enter key 14a is pressed, and then one memory card 3 is attached to the memory card interface 13. The timing of mounting the memory card 3 may be before the input of the PLU code or before the input of the enter key 14a.

Through the above sales operation, the PLU code of the corresponding product, the confirmed weight data, and the amount (price) data of the corresponding product corresponding to the weight are automatically written in the memory card 3. Therefore, the salesperson removes the memory card 3 from the memory card interface 13 and hands it to the customer together with the packaged product.

On the other hand, the customer puts the merchandise and the memory card received from the salesperson into the shopping basket provided in the shop together with other purchased commodities, and when the shopping in the store is finished, bring the shopping basket to the accounting place. go.

Then, when a clerk who operates the POS terminal 2 at the checkout place, a so-called cashier, receives a shopping basket from a shopper, the sales data of the customer-purchased product in the basket is sent to the POS terminal 2 by one. Register each item.

In this case, in the case of a merchandise other than the merchandise sold by merchandise, the bar code scanner 2 using the merchandise code for specifying the merchandise, that is, the PLU code as the input means.
8 or the keyboard 26 is used to register. By doing so, the sales data of the number of sales of the registered product and the sales amount are accumulated in the PLU file 51 for each PLU code, and the sales amount is added to the total amount memory 53. The total amount memory 53 is cleared to "0" in response to the input of the PLU code of the first registered product for one shopper.

On the other hand, in the case of a product sold by weight, the corresponding memory card 3 is replaced by the memory card interface 2
Register by attaching to 3. By doing so, the PLU code, the sales weight data and the sales amount data recorded in the memory card 23 are read,
Preset data such as a product name corresponding to the PLU code is read from the LU file 51. Then, as in the case of registration of a product other than the measure sale, the product name and the sales amount in the card data are displayed on the display 30, and the printer 32 displays the product name, the sales weight, the sales amount, etc. on the receipt paper and the journal paper. Detailed data is printed.
Further, the number of sales = 1 and the sales amount are accumulated in the sales amount data and the sales amount data corresponding to the PLU code of the PLU file 51. Further, the sales amount is added to the total amount memory 53. When the memory card 3 is attached to the memory card interface 23 at the time of the first registered product for one shopper, the total amount memory 53 is cleared to "0" in response to the installation.

In this way, when one shopper completes the registration of all the products purchased, the cashier operates the closing key 26a to declare the end of registration. By doing this, the PO
In the S terminal 2, the accounting work for the total amount of all the products including the merchandise sold is processed and the change is displayed and the receipt is issued. Therefore, the cashier hands the change and the receipt to the customer as necessary.

The cashier pulls out the memory card 3 from the memory card interface 23 and collects it. In this way, the recovered memory card 3 is brought back to the meat sales floor and used again.

As described above, according to the present embodiment, the data regarding the merchandise sold by the MCI / F charge scale 1 installed at the sales floor of the merchandise, that is, the PLU code, the sales weight, and the sales amount of money. The memory card interface 1 is used as a means for transmitting the metered sales data to the POS terminal 2 installed at the checkout place.
The memory card 3 in which writing and reading of data can be freely performed by 3, 23 can be used.

Therefore, the labor required for the printer maintenance work can be eliminated as compared with the conventional case where the charge scale with a label printer for printing the sales data on the bar code label is used. In addition, since the troublesome work of attaching the barcode label to the packaged product is eliminated, the labor is greatly reduced. Moreover, there is no longer the need for a shopper to wait due to running out of paper or paper jam, and it is possible to realize efficient and efficient measurement and sales operations.

Further, since the memory card 3 can be used repeatedly as many times as possible, the cost can be reduced as compared with the conventional case where a disposable bar code label is used, and an environmental problem related to waste disposal is adversely affected. Lost.

Further, the MCI / F toll balance 1 prohibits the subsequent metered sale operation until the memory card 3 is removed from the memory card interface 13 after the metered sale data is written in the memory card 3. . Therefore, even if the salesperson forgets to take out the memory card 3 and tries to sell the next customer by weight, the sales data for the previous customer written in the memory card 3 can be surely protected. In this case, by providing the MCI / F charge balance 1 with a means for issuing a display to warn the removal of the card, a buzzer sound, etc. after the data is written in the memory card 3, the effect is further enhanced. .

In the embodiment described above, the charge balance 1 with MCI / F having the balance section 18 as an example of the commodity measuring and selling apparatus is illustrated.
Although the case where the product sales amount is measured as the weight is shown, the product measurement sales device that measures the product sales amount as the length and calculates the charge according to the product sales amount, for example, when selling cloth. Alternatively, the present invention can be applied to a product metering and selling device that measures the product sales amount as a volume and calculates a charge according to the product sales amount, such as when selling drinking water.

Although the memory card 3 is used as the portable recording medium in the above embodiment, the present invention is not limited to this, and a magnetic card, an optical card or the like may be used. It is also possible to use a proppy disk by providing a floppy disk driver in each of the merchandise quantity selling device and the cash registering device.

Further, in the above-described embodiment, the memory card 3 is inserted / removed every time one metered product is measured and sold in the MCI / F charge balance 1. However, one shopper purchases a plurality of kinds of metered products. In this case, it is advisable to write the metered sales data of all commodities on one memory card 3. That is, the RAM of the charge balance with MCI / F 1
A plurality of work memories 42 are provided in 12. And MCI
As shown in FIG. 10, the CPU 10 of the charge balance with F 1
In the same process as ST1 to ST9 in FIG. 4 in the above embodiment, the end key for declaring the end of the metered sale for one customer is input in ST13 while sequentially changing the work memory 42 to which the mass sale data is set. The program is configured so that all the contents of each work memory 42 are written in the memory card 3 when the input of the end key is detected until the operation is repeated. With such a configuration, when one shopper purchases a plurality of types of merchandise sold products, the weight sale data of all the products can be written in one memory card 3, so that a customer who purchases a plurality of types of measurable products can be written. The handling of the memory card 3 becomes easier.

Further, when there is only one kind of merchandise for sale, the PLU code can be omitted from the merchandise sale data written in the portable recording medium by the merchandise merchandise sale device.
In this case, in the cash registering device, the weighing sale data read from the portable recording medium is all registered as data of one product.

If there is only one kind of merchandise to sell, it is also possible to introduce a self-service in which the customer himself / herself measures and purchases the desired quantity. Similarly,
In recent years, a self-scanning system in which the customer himself / herself reads and operates a bar code attached to a purchased product has been considered as a cash registration device, and a data reading device for a portable recording medium is also used in this kind of cash registration device. By adding it, it becomes possible to introduce self-service accounting services.

In the above embodiment, if the MCI / F charge balance 1 is connected to the host computer to collect the data of the PLU file 41 for merchandise sold, the sales data of each merchandise sold is Since the registration process is performed in the PLU file 41 for the merchandise sale product, it is possible to omit the registration process of the sales data of the merchandise sale product in the PLU file 51 in the card input process in the POS terminal 2.

In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[0068]

As described above in detail, according to the present invention, a portable recording medium that can be repeatedly used is used as a means for transmitting data related to products that are sold by the product sales and measurement device to the cash register device. Therefore, it is possible to provide a merchandise sales registration data processing system capable of significantly reducing the labor required for maintenance work and eliminating the adverse environmental effects due to cost savings and waste reduction.
