The product data file stores product information corresponding to the product code. The RAM 22 is a data storage memory used in normal processing. The communication IF 29 is a communication unit that performs communication with the outside through a LAN.

  FIG. 3 shows a data storage unit 30 provided in the RAM 22. The storage parts A and B store weight reduction values supplied from the first weighing unit, and the storage parts C and D store product information based on product codes. The storage parts E and F store the weight increase value supplied from the second weighing unit. The weight decrease value stored in the storage part A and the weight increase value stored in the recording part E are associated with the product information C, and the weight reduction value stored in the storage part B and stored in the recording part F. The weight increase value is associated with the product information D. In addition, the data storage unit 30 stores a storage unit that stores a count value Z that indicates the number of times the product is taken out from the product mounting table 11 and a storage unit that stores a count value X that indicates the number of times the product is placed on the product mounting table 12. (Not shown). The data stored in the data storage unit 30 is initialized to zero when the self-chuck out operation is started.

  In such a configuration, the operation of the self-chuck out process will be described. FIG. 4 is a flowchart of self-chuck out processing performed by the CPU of the self-checkout device. The CPU 20 starts a self-checkout process and detects a decrease change in the weighing data of the first weighing unit 13 (S1). Specifically, if the difference between the measurement data before the change and the measurement data after the change is equal to or greater than a predetermined determination value, it is determined that there is a change in the measurement data. When there is a decrease in the measurement data, the CPU 20 adds 1 to the number of times Z stored in the data storage unit (S2). Next, the difference between the measurement data before the change and the measurement data after the change is used as the weight value of the product. If the number of times Z is 2, the product weight value is written in the data storage part B (S3).

  Next, the CPU 20 detects whether or not a product code has been input (S4). The product code is input by reading a bar code with a scanner or by an input operation on an operation screen of a display with a touch panel. When there is an input of a product code, the product data file stored in the hard disk drive 21 is referred to, and the product data corresponding to the input product code is read from the product data file. The product data is written in the memory part C (S5). If the number of times is 2, the read product data is written in the storage part D (S5).

  In addition to the detection of the decrease change of the weighing data of the first weighing unit, the increase change of the weighing data of the second weighing unit is also detected (S6). Specifically, if the difference between the measurement data before the change and the measurement data after the change is greater than or equal to a predetermined determination value, it is determined that the measurement data has increased. When there is an increase in the measurement data, the CPU 20 adds 1 to the number of times X stored in the data storage unit (S7). The CPU 20 writes the difference between the measurement data before the change and the measurement data after the change as the weight value of the product, and writes it in the data storage unit E if the number of times is 1 (S8). If the number X is 2, the product weight value is written in the data storage part F (S8).

  Next, following the process of S5 or S8, it is detected whether the number of times Z stored in the data storage part is 1 and the number of times X is 1 (S9). If the number of times Z is 1 and the number of times X is 1, then it is detected whether the weight value of the product stored in the data storage part E is 0 (S10). If the weight value of the product is 0, the process returns to the detection of the decrease in the amount of the first weighing unit 13 and the detection of the increase in the amount of the second weighing unit 14. If the weight value of the product is not 0, it is checked whether the weight value of the product stored in the storage part A and the weight value of the product stored in the storage part E are the same. That is, it is checked whether the product taken out from the product placement table 11 is placed on the product placement table 12 (S11). If the weight value is the same, the product data stored in the storage part C in association with the weight value of the product stored in the storage part A is added to the sales data file of the hard disk drive 21 and written (S12). ). Since the weight check process for the product is completed, the data storage parts A and E and the numbers of times Z and X are set to 0 (S12). Then, the process proceeds to detection of settlement input (S19). If the weight value of the storage part A and the weight value of the storage part E are not the same, the weight value of the product stored in the storage part E and the number X are set to 0 (S21). Then, the process returns to the detection of the decrease in the amount of the first weighing unit and the detection of the increase in the amount of the second weighing unit. At this time, a message “Please put the scanned product on the product placement table” is displayed.

  If the number Z and the number X are not 1, then it is detected whether the number Z is 2 and the number X is 1 (S13). When the number of times Z is 2 and the number of times X is 1, it is checked whether the weight value stored in the storage part A and the weight value stored in the storage part E are the same. That is, it is checked whether the product taken out from the product placement table is placed on the product placement table (S14). If the weight value is the same, the product data stored in the storage part C in association with the weight value of the product stored in the storage part A is additionally written in the sales data file of the hard disk drive 21 (S15). ). In addition, since the number X of products to be placed on the product mounting table 12 is still 1, the value of the number X is maintained and the weight check processing for one product is completed, so the data storage parts A and E and the number of times Z are set to 0. (S15). Then, the process returns to the detection of the decrease in the amount of the first weighing unit and the detection of the increase in the amount of the second weighing unit. If the weight value of the storage part A and the weight value of the storage part E are not the same, the weight value and the number of times X stored in the storage part E are set to 0 (S15). Then, the process returns to the detection of the decrease change of the first weighing unit 13 and the detection of the increase change of the second weighing unit 14.

  If the number of times Z is 2 and the number of times X is not 1, then it is detected whether the number of times X is 2 (S16). When the number X is 2, it is checked whether the weight value of the product stored in the storage part B and the weight value of the product stored in the storage part F are the same. That is, it is checked whether the product taken out from the product placement table 11 is placed on the product placement table 12 (S17). If they are the same, the product data stored in the storage part D in association with the weight value of the product stored in the storage part B is additionally written in the sales data file of the hard disk drive 21 (S18). Since the product weight check process for the product is completed, the data storage parts B and F and the number of times X are set to 0 (S18). Then, the process proceeds to detection of accounting input (S19). If the weight value of the storage part B and the storage part F are not the same, the weight value stored in the storage part F is set to 0 and the number X is set to 1 (S22). Then, the process returns to the detection of the decrease change of the first weighing unit 13 and the detection of the increase change of the second weighing unit 14. When the number of times Z is not 0 and the number of times X is not 2, the process returns to the detection of the decrease in the first weighing unit 13 and the change in the increase of the second weighing unit 14.

  After the process of S11 or S18, the presence / absence of accounting input is detected (S19). Accounting input is input by touching an accounting button on the operation screen of the display 2. When the accounting input is detected, accounting processing (S20) is performed based on the product data purchased in this transaction stored in the sales data file.

  In this embodiment, for example, for an operation in which a customer takes out a product A from the product placement table 11 and takes out another product A from the product placement table 11 before placing the product A on the product placement table 12, The processing operation will be described with reference to FIG.

  The customer starts the self-checkout process by pressing a start button provided on the screen of the display 2. Then, the commodity A is taken out from the commodity placing table 11 on which the commodity to be purchased is placed. The CPU 20 adds 1 to the number of times Z (S2) because the first weighing unit 11 detects a decrease in weight (S1). Then, since the number of times Z is 1, the weight of the product A weighed is written in the data storage part A (S3). Next, the customer reads the barcode attached to the product A with the scanner 3. The scanner 3 decodes the read barcode and outputs a product code. When a product code is input from the scanner 3 to the CPU 20 (S4), the corresponding product data is read from the product data file, and since the number of times Z is 1, it is written in the counter storage part C (S5). In the state where the product A is taken out from the product mounting table 11, since the number of times Z is 1 and the number of times X is 0, the determinations of S9, S13, and S16 are all NO, and the change in the weight reduction of the first weighing unit 11 And waiting for detection of a change in increase of the second weighing unit 12.

  When the customer takes out the product A from the product placement table 11 before placing the product A on the product placement table 12, the CPU 20 detects the weight reduction (S1), so that the number of times Z is reached. 1 is added (S2). Then, since the number of times Z is 2, the weight of the weighed product A is written in the data storage part B (S3). Next, the customer reads the barcode attached to the product A with the scanner 3. When the product code is input from the scanner 3 (S4), the corresponding product data is read from the product data file, and since the number of times Z is 2, it is written in the storage part D (S5). Further, in the state where the product A and the product A are taken out from the product mounting table 11, the number of times Z is 2 and the number of times X is 0. Therefore, the determinations of S9, S13, and S16 are all NO, and the first weighing unit 11 This is in a state of waiting for detection of a change in the amount of decrease and detection of an increase in the amount of the second weighing unit 12.

  When the customer places the product A first taken out of the product placement table 11 out of the product placement table 11 on the product placement table 12, the CPU 20 detects that the second weighing unit 12 has increased in weight (S6), and the number of times 1 is added to X (S7). Then, since the number of times X is 1, the weight of the product A weighed is written in the data storage part E (S8). Further, in the state where the product A is taken out from the product placement table 11 and the product A is placed on the product placement table 12, the number of times Z is 2 and the number of times X is 1, so it is detected in S13 and stored in the storage part A. It is checked whether the stored weight value of the commodity A is the same as the weight value of the commodity A stored in the storage part E (S14). If the weight values are the same, the product information stored in the storage unit C is additionally written in the sales data file of the hard disk drive (S15).

  The customer places the remaining product a on the product placement table 12. When the product A is placed on the product mounting table 12, the CPU adds 1 to the number X (S7) because the second weighing unit detects an increase in weight (S6). Then, since the number of times X is 2, the weight value of the measured product A is written in the data storage part F (S8). In the state where the product A is placed on the product mounting table 12, since the number X is 2, the weight value of the product A detected in S16 and stored in the storage unit B and stored in the storage unit F It is checked whether the weight value of the product A is the same (S17). If the weight value is the same, the product information stored in the storage part D is additionally written in the sales data file of the hard disk drive (S18).

  In addition, the customer may newly take out another product from the product mounting table 11 before placing the product A on the product mounting table 12. The CPU 20 adds 1 to the number of times Z (S2) because the first weighing unit 12 detects a decrease in weight (S1). Then, since the number of times Z is 1, the weight value of another weighed product is written in the data storage part A (S3). Next, the customer reads a barcode attached to another product with a scanner. When the product code is input (S4), the corresponding product data is read from the product data file, and since the number of times Z is 1, it is written in the data storage part C (S5). Further, in a state in which the product A is taken out from the product placement table 11 and another product is taken out from the product placement table 11, the number of times Z is 1 and the number of times X is 1, so that it is detected in S9. In this case, since the value of the data storage part E is 0 (S10), it is in a state of waiting for detection of a decrease change of the first weighing unit 11 and detection of an increase change of the second weighing unit 12.

  In addition, when the customer takes out one product from the product placement table 11 and places the one product on the product placement table 12 before taking out another product, this state is detected in S9, and the storage unit A It is checked whether the weight value of the one product stored in 1 is the same as the weight value of the one product stored in the storage part E (S17). If the weight values are the same, the product information stored in the storage unit C is additionally written in the sales data file of the hard disk drive (S12).

  When the customer finishes placing all the products to be purchased on the product mounting table 12, the customer inputs the accounting by touching the accounting button on the operation screen of the display with a touch panel. When detecting the accounting input, the CPU performs accounting processing (S25) based on the product data purchased in this transaction stored in the sales data file. The customer selects a cash or card payment method by operating the screen. Based on the selected payment method, the CPU 20 performs an accounting process for the purchase price of the purchased product data. At this time, in the case of cash, the customer puts cash into the coin slot 6 and the banknote slot 8, and in the case of a card, the customer passes the card through the card slot 4. The change is returned from the coin outlet 7 and the banknote outlet 9. Then, a receipt is issued from the printer 28, and the checkout process ends.

  As described above, when the customer operates the self-chuck-out device according to the present embodiment, the customer takes out one product from the product placement table 11 and inputs the product code and places it on the product placement table 12. Before, the operation of taking out the next product from the product placement table 11 becomes possible. As a result, the self-chuck out process by the customer's product registration operation can be performed quickly.
