The operation flow of such a sales system will be described with reference to FIGS. 6 and 7. FIG. 6 shows a flow related to the operation of the customer, and FIG. 7 shows a flow related to the operation of the cashier operator. First, the customer operation is performed in step S11 (hereinafter, abbreviated as S11, etc.) of FIG.
The customer who visits the store receives the shopping card 3 and the tray 4,
After deciding the product to purchase, insert the shopping card 3 into the card insertion slot 14 of the unloading scale 6 on which the product is placed (S1).
2) Move the desired amount of product to Tray 4 (S1
3) Press the completion key 13 (S14). By this operation, the bar code of the purchased product is printed on the shopping card 3, and the product is ejected from the card insertion port of the withdrawal scale 6 (S15). If shopping is to be continued, the process returns to S12 and the same operation is repeated, and when the shopping is completed, the product and the shopping card 3 are brought to the cash register (S17).

The operation of the cashier operator receives the shopping card from the customer in S21 of FIG. 7 and scans the bar code of the shopping card with the wand scanner (S2).
2). At this time, every time the barcode is scanned, the product name and price are displayed on the customer's display at the cash register,
It is possible to manage the performance of individual products by accumulating the sales weight and price of the products. When there is a product other than the shopping card, product registration is performed (S23). Packaging / accounting processing is performed (S24).

Next, the operation of the unloading scale will be described with reference to the flow chart of FIG. In S31, the current weight placed on the plate is weighed. In S32,
It is determined whether or not the card sensor detects a shopping card, and if “NO”, the process proceeds to S39, where “YE
If "S", the process proceeds to S33. In S33, R
The current weight value is subtracted from the previous weight value stored in the AM to obtain the weighing data retrieved this time. Then, the unit price set by the unit price setting switch is read, multiplied by the weighing data to calculate the price, and the price is displayed on the display unit. In S34, it is determined whether or not the completion key is pressed, and if "NO", the process returns to S31 and "YES".
If so, the process proceeds to S5.

In step S35, the platen roller is rotated to align the printing position of the shopping card with the position of the thermal head based on the signal from the printing position sensor. S
In 36, the NONPLU bar code and the print position mark are printed based on the product number and the price data calculated in S33, and the readable character and the price are printed. In S37, the platen roller is reversely rotated to eject the shopping card. In S38, the current weight value is written in the previous weight value provided on the RAM, the weight and price are set to zero, and the balance is reset to zero. Then, the process returns to S31.

In S39, as in S33, the current weight value is subtracted from the previous weight value to determine whether or not the minimum display unit (for example, 5 g) has been removed,
If "YES", the process proceeds to S40, and if "NO", the process returns to S31. In S40, since the item has been removed without inserting a shopping card here, a guidance message "Please insert a shopping card!" Is displayed. In S41, the buzzer is sounded for a predetermined time to notify that the shopping card has been removed without inserting it. Then, the process returns to S31.

A. The recording means may record the weighing data as the withdrawn amount instead of the price. In this case, when reading out the record data, the cashier may read the corresponding unit price of the product file from the product number recorded together and multiply it by the weighing data to calculate the price.

B. Even with a system that does not use a shopping card, for example, a customer's fingerprint can be read by a scale so that this data can be read by another scale or cashier, and the weighing data is recorded for each of these data and settled at the cashier. You may allow it. Further, as disclosed in the above-mentioned Japanese Patent Laid-Open No. 4-149799, it is also possible to print and record a sheet or a label with a NONPLU bar code and read it with a cash register.

C. Connect each scale and cash register so that it can be updated,
When you read a shopping card with an ID code recorded on a certain scale, a file is created in a storage means that can be read and written by any device, and a purchase information area is created and written using the card number as a key. If you take out the product with another scale, add it to this area and write it in.If you read the shopping card at the cashier at the time of production, the data will be read from the corresponding purchase information area and settled, then this area May be deleted.

D. Instead of printing and recording on the card, the card may be provided with a readable / writable storage means, for example, as a magnetic card or an IC card, the data withdrawn by each scale may be written and recorded in the storage means of the card. . In this case, the device for reading and writing the card corresponds to the card detecting means. The cashier reads this memory information, makes a payment, and clears it.

E. It is not limited to measuring the weight of the withdrawn products, but like "croquette" and "haruru".
In the case of products sold in pieces, the unit price may be set as a unit weight and the number may be counted by dividing from the weight. In the balance in this case, a new setting switch is provided, and when the switch is "ON" or "OFF", a similar flag is provided in the product data at the cash register to switch the weight and number processing.

F. A tenant such as a supermarket that occupies a corner of a large sales floor may have only one scale and handle only one product. g. The bar code reading device of the cash register is not limited to the wand scanner, and a fixed scanner capable of simultaneously reading a plurality of bar codes may be used.

H. A plurality of weighing units may be provided on one scale. i. If the measuring section number corresponds to the product number, the measuring section number may be set in the product number setting switch.
