When the weighing sales system 1 is used in the second mode, the weighing sales system 1 is arranged with the display unit 12, the key operation unit 13, and the reader / writer unit 21 all facing the purchaser. Used. In the following example, it is assumed that one type of product is handled, and that selection of the product is unnecessary.

  FIG. 6 is a flowchart showing the flow of the weighing and selling work when the weighing and selling system 1 is used in the second mode. First, the seller switches the weighing sales system 1 to the second mode (step S21). Specifically, as shown in FIG. 4, when the seller touches the mode switching key K1 displayed on the display unit 12, an instruction for switching the mode is input. Upon receiving the instruction input from the mode switching key K1, the control unit 16 causes the display unit 12 to display a work screen for the second mode. On the work screen for the second mode, as shown in FIG. 7, information 12a such as the measured value, unit price, and sales price of the product is displayed, and a guidance message 12c for the purchaser is displayed.

  On the display unit 12, a guidance message “Please place product on the weighing platform” is displayed. The purchaser places the product on the weighing platform 11a according to the guidance message (step S22). When the product is placed on the weighing table 11a, the weight sensor 11b measures the weight of the placed product and transfers the measured value to the control unit 16 (step S23). Then, the control unit 16 calculates the sales amount based on the measurement value, and displays the measurement value and the sales amount on the display unit 12 (step S24).

  In the second mode, when the measured value of the product is stable and the sales amount is determined, the control unit 16 instructs the settlement unit 20 via the communication unit 15 and the communication line 30 to activate the settlement operation. Transmit (step S25). Upon receiving the instruction, the control box 22 of the settlement unit 20 activates the communication operation of the reader / writer unit 21 and waits for an IC card to approach. At the same time, the control unit 16 transmits sales amount information to the settlement unit 20 via the communication unit 15 and the communication line 30.

  The display unit 12 displays the weight of the product and the sales price, and also displays a guidance message “Please bring the IC card closer”. In accordance with this guidance message, the purchaser brings the IC card in which his / her electronic money information is recorded closer to the antenna unit 21a of the reader / writer unit 21. The reader / writer unit 21 reads the remaining amount in the IC card and performs the settlement process by rewriting the remaining amount information in the IC card to the amount obtained by reducing the sales amount (step S26). When the settlement process in the settlement unit 20 is completed, the settlement result is transferred from the control box 22 to the main body unit 10, and the settlement result and a guidance message “settlement completed” are displayed on the display unit 12.

  The purchaser confirms the settlement result displayed on the display unit 12, picks up the product from the weighing platform 11a, and takes the product out of the store (step S27). When the product is removed from the weighing table 11a and the measurement value of the weighing unit 11 returns to the zero point, the guidance message on the display unit 12 returns to “Place the product on the weighing table”, and the weighing and sales work is completed.

  In the second mode, if the purchaser removes the product from the weighing platform 11a before the settlement process is performed after the settlement section 20 is activated (between step S25 and step S26), the settlement section 20 Checkout operation is disabled. This is realized by transmitting an instruction for invalidating the settlement operation from the control unit 16 to the settlement unit 20 when the measurement value of the measurement unit 11 returns to the zero point. The control box 22 of the settlement unit 20 invalidates the settlement operation by erasing the received sales amount information and stopping the communication operation of the reader / writer unit 21. Further, the control unit 16 returns the guidance message on the display unit from “Please bring the IC card closer” to “Place the product on the weighing table”. Thereby, the purchaser can cancel the purchase after confirming the sales amount displayed on the display unit 12. Further, after the purchase is stopped, other purchasers can use the weighing and selling system 1 as usual.

Moreover, it is good also as a structure which can specify a fixed amount product by providing a barcode reader in the main-body part 10, and reading the barcode attached | subjected to fixed amount products, such as a PET bottle and a can drink, with a barcode reader. When a product is designated by the key K4 or the barcode reader, information on the sales amount of the designated product is transmitted to the settlement unit 20, and the settlement unit 20 performs settlement with electronic money.

  Moreover, although the above-described measurement and sales system 1 performs only the settlement process using electronic money, even if it is configured to selectively execute the settlement process using electronic money and the settlement process using cash exchange. Good. For example, as shown in FIG. 9, a first cassette C1 storing a receipt for printing a settlement result by electronic money, and a second cassette storing a receipt for printing a settlement result by sending and receiving cash. C2 may be prepared, and these may be selectively set in the output unit 14 for use. Further, when the first cassette C1 is set in the output unit 14, the communication unit 15 may be controlled so that communication between the main body unit 10 and the settlement unit 20 is activated.

  In addition, the weighing and selling system 1 may be configured so that the settlement result transferred from the settlement unit 20 to the main body unit 10 can be stored and aggregated in the control unit 16. Further, in addition to the settlement result such as the settlement time, the sale product, the sale price, etc., the control unit 16 may be configured to store / aggregate accompanying information such as the purchaser's sex and age. If it does in this way, these information can be utilized as sales information.

  In the second mode, one type of product is handled. However, a plurality of products may be selected in the second mode. For example, on the work screen for the second mode, a selection key for selecting a product may be displayed on the display unit, and the product information may be called by the purchaser operating the selection key. In addition, an RFID tag storing information such as the unit price of the product is attached to a container (tare) placed together with the product on the weighing platform 11a, and information on the RFID tag is obtained by a predetermined sensor provided on the main body 10 side. You may comprise so that the unit price of goods may be recognized automatically by reading.

  In the second mode, no receipt is issued. However, a receipt may be issued from the output unit 14 by the purchaser's operation or automatically after the settlement process is completed. Good. In the above configuration, the print key is arranged on the key operation unit 13. However, the print key may be displayed on the display unit 12. Further, the display mode of the mode switching key K1 and the work screen displayed on the display unit 12 is not limited to the examples of FIGS. 4, 5, and 7, and may be other display modes.
