Therefore, it has a collision prevention function called an anti-collision method. With this function, when customer-purchased products 6A, 6B, 6C,... For one commercial transaction housed in a container 5 such as a shopping basket are placed on the tag antenna plate 3, these products 6A, 6B, 6C,. The data of the electronic tags 7A, 7B, 7C,. The electronic tag data read by the electronic tag reader 2 is sequentially transmitted to the POS terminal 1. In the POS terminal 1, based on the electronic tag data read from the electronic tags 7A, 7B, 7C,... By the electronic tag reader 2, the sales data of the products 6A, 6B, 6C,. It has become. In addition, each goods 6A, 6B, 6C, ... need not necessarily be accommodated in the container 5.

  The electronic tags 7A, 7B, 7C,... Are also called wireless tags, RFID (Radio Frequency Identification), IC tags, etc., and have already been put into practical use. In the present embodiment, the electronic tags 7A, 7B, 7C,... Attached to the products 6A, 6B, 6C,. The product tag memory stores at least a tag-specific ID code such as a serial number set at the time of tag manufacture and a product code for specifying a product to which the product tag is attached.

  FIG. 2 is a block diagram showing a main configuration of the POS terminal 1. The POS terminal 1 is an aspect of a merchandise sales data processing apparatus, and includes a CPU (Central Processing Unit) 11 as a control unit body. Further, a ROM (Read Only Memory) 12 in which fixed data such as programs are stored in advance, and a RAM (Random Access Memory) in which various memory areas for storing variable data such as input data and arithmetic processing data are formed. 13) Clock unit 14 for measuring the current date and time, communication controller 15 for controlling data communication with the store server connected online, electronic tag reader interface 16 to which the electronic tag reader 2 is electrically connected, keyboard A keyboard controller 18 that captures key signals corresponding to the 17 operation keys; a first display controller 20 that controls screen display on the operator display 19; a second display controller 22 that controls screen display on the customer display 21; A pre-control for controlling the printing operation of the printer 23 that performs printing and the like Motor controller 24, a drawer 25 for accommodating cash, etc., and a I / O (Input / Output) port 27 for outputting a respective driving signal to the buzzer 26 emit such as data reading sound. The CPU 11, the ROM 12, the RAM 13, the clock unit 14, the communication controller 15, the electronic tag reader interface 16, the I / O port 27, and the controllers 18, 20, 22, 24 of various input / output devices are connected to an address bus, a data bus, etc. They are connected by a bus line 28.

  The keyboard 17 is provided with at least a numeric key 31 for numeric data and a closing key 32 as a closing declaration means for declaring closing of one commercial transaction.

  In the RAM 13, a commodity item buffer 41 capable of storing and storing a plurality of commodity sales data, an electronic tag data buffer 42 capable of storing and retaining a plurality of electronic tag data, and numerical data input by a numeric key 31 are stored. At least a numerical buffer 43 for temporary storage is formed.

  As shown in FIG. 3, the merchandise item buffer 41 has an area for storing a plurality of merchandise sales data composed of items of merchandise code, merchandise name, unit price, sales points, and sales amount, and the total of the sales points and sales amount. It has an area for storing data (total sales score N, total sales amount M).

  As shown in FIG. 4, the electronic tag data buffer 42 has a plurality of areas for storing electronic tag data. The electronic tag data buffer 42 stores and holds electronic tag data in order from the area of area number 1. When electronic tag data is stored and held up to the area of area number MAX, the subsequent electronic tag data is stored in area number 1. Overwrites in order from the area.

  In the POS terminal 1 having such a configuration, when the system is started by turning on the power, the CPU 11 executes the control process of the procedure shown in the flowcharts of FIGS. 5 and 6. This process is controlled according to a program stored in the ROM 12, for example.

  That is, the CPU 11 instructs the electronic tag reader 2 connected via the electronic tag reader interface 16 as ST (step) 1 to start. Thereby, the electronic tag reader 2 modulates a read signal for reading the electronic tag, and continuously transmits the modulated radio wave from the antenna 4. And it waits for the response wave from an electronic tag to be received by the antenna 4. When the response radio wave is received, the radio wave is demodulated, and the response data, that is, the electronic tag data stored in the memory of the electronic tag is transmitted to the POS terminal 1.

  Therefore, the CPU 11 waits for reception of electronic tag data as ST2. When the electronic tag data is received from the electronic tag reader 2 (YES in ST2), the electronic tag data buffer 42 is searched as ST3. Then, it is determined whether or not the same data as the received electronic tag data is stored in the electronic tag data buffer 42. In this determination process, the electronic tag data buffer 42 is searched with the ID code unique to the tag included in the received electronic tag data, and the presence / absence of electronic tag data including the same ID code is determined and stored. If the same data exists, it is determined that there is the same data, and if not stored, it is determined that the same data does not exist.

  As a result, when it is determined that the same data exists (YES in ST4), the CPU 11 discards the electronic tag data received as ST5 without adding it to the electronic tag data buffer 42. Thereafter, the process returns to ST2 and waits for reception of the next electronic tag data.

  When it is determined that there is no identical data (NO in ST4), the CPU 11 adds the electronic tag data received as ST6 to the electronic tag data buffer. Thereafter, it is determined whether or not the electronic tag data added to the electronic tag data buffer 42 in ST7 is data of a product tag attached to each product. Here, if it is not the electronic tag data read from the product tag, the process returns to ST2 and waits for reception of the next electronic tag data.

  When the received electronic tag data is electronic tag data read from the product tag, that is, data including the product code together with the ID code, the CPU 11 determines the product name based on the product code included in the electronic tag data as ST8. Product data such as unit price is acquired (product name acquisition means). That is, the POS terminal 1 includes a product data file in which product data such as a product name and a unit price is preset corresponding to the product code of each product, and the CPU 11 stores the product data file with the product code acquired from the electronic tag data. To obtain the product data of the product name and unit price set corresponding to the product code. The product data file may be omitted by storing product data such as product name and unit price in the product tag memory together with the product code.

  When the CPU 11 acquires the product data such as the product code, the product name, and the unit price, next, in ST9, the sales number is set to “1”, the sales amount is the unit price, and the product code, product name, unit price, sales point, and sales amount are set. Product sales data consisting of Then, this product sales data is added to the product item buffer 41. At this time, if product sales data having the same product name and unit price is already stored in the product item buffer 41, this item is added to the sales score and sales amount of the product sales data having the same product name and unit price. Add the sales points and sales amount of the product sales data.

  Next, the CPU 11 adds the sales score and sales amount of each product sales data stored in the product item buffer 41 as ST10, calculates the total score N and total amount M, and calculates the total area of the product item buffer 41. Is updated (tag number counting means). In ST11, the product name, unit price, total amount [subtotal], etc. are displayed on the operator display 19 and the customer display 21 (product name display means). In ST12, a drive signal is sent to the buzzer 26 to sound a commodity reading confirmation sound.

  Thereafter, the CPU 11 determines whether or not the tightening key 32 has been operated and input as ST13. If the closing key 32 has not been operated, the process returns to ST2 and waits for reception of the next electronic tag data.

  When the tightening key 32 is operated, the CPU 11 proceeds to the process of ST21 in FIG. That is, a message screen for instructing the operator to input the total number of products purchased by the customer is displayed on the operator display 19. Then, the CPU 11 waits for the total score to be input as ST22. Here, when the numerical data k is input by the operation input of the numeric key 31, the numerical data k is regarded as the total number of products purchased by the customer (score input means). In ST23, the total score k is compared with the total score N stored in the product item buffer 41 (comparison means).

  As a result, when the total score k input by the number is smaller than the total score N stored in the product item buffer 41 (YES in ST24), the CPU 11 calculates the total score of the products purchased by the customer as ST25. Is displayed on the operator display 19 (message display means). Then, the process returns to ST22 and waits for the total score to be input again.

  If the total score k input by the number is larger than the total score N stored in the product item buffer 41 (NO in ST24, YES in ST26), the CPU 11 attaches the product purchased by the customer as ST27. A message screen for notifying the operator of the reading error of the electronic tag is displayed on the operator display 19 (message display means). Thereafter, the process proceeds to another process.

  When the total score k input by the number matches the total score N stored in the product item buffer 41 (NO in ST24, NO in ST26), the CPU 11 stores it in the product item buffer 41 as ST28. Based on the merchandise sales data, a closing process is performed to settle the price of the merchandise sold as one commercial transaction. The tightening process includes a process of calculating a change amount when the price is paid for the total amount of the business transaction, displaying the change amount on the operator display 19 and the customer display 21, and opening the drawer 25. In addition, the printer 23 is driven to issue a receipt printed with commercial transaction details data such as a product name, sales points, sales amount, total points, total amount, etc. stored in the product item buffer 41 (payment settlement) means).

  Here, the CPU 11 functions as a settlement control means that permits settlement on condition that the total score k input by the number matches the total score N stored in the commodity item buffer 41.

  When this tightening process ends, the CPU 11 clears the merchandise item buffer 41 in ST29. At this time, the electronic tag data buffer 42 is not cleared. Thereafter, the process returns to ST2 and waits for reception of the next electronic tag data.

  In the present embodiment configured as described above, when the POS terminal 1 is turned on, a reading radio wave for reading the electronic tag is continuously transmitted from the antenna 4 of the electronic tag reader 2. Here, when an electronic tag enters the communication area of the antenna 4, electronic tag data stored in the memory of this electronic tag is read by the electronic tag reader 2 in a contactless manner and transmitted to the POS terminal 1.

  Now, suppose that the customer comes to the accounting place where the POS terminal 1 is installed in order to purchase a large number of products 6A, 6B, 6C,. In this case, a so-called cashier in charge of accounting places the products 6A, 6B, 6C,... On the tag antenna plate 3. Then, the electronic tags 7A, 7B, 7C,... Attached to the respective products 6A, 6B, 6C,... Respond to the radio waves read from the antenna 4 and include the ID code and the product code, respectively. Send data response radio waves.

  For example, when a response radio wave from the electronic tag 7A attached to the product 6A is received by the antenna 4, the electronic tag data including the ID code and the product code stored in the electronic tag 7A is read by the electronic tag reader, and the POS terminal 1 is sent. Thereby, in the POS terminal 1, it is determined whether or not the electronic tag data including the ID code in the electronic tag data is stored in the electronic tag data buffer 42. If not stored, the electronic tag data is added to the electronic tag data buffer 42. Further, the product name and unit price of the product A are acquired based on the product code in the electronic tag data, and product sales data is generated together with the sales score (= 1) and the sales amount (= unit price × sales score). The product sales data is stored in the product item buffer 41. Also, product name, unit price. The number of sales, the sales amount, etc. are displayed on the operator display 19 and the customer display 21. Note that the merchandise item buffer 41 is cleared after the last customer closing process. Therefore, the total score data N of the product item buffer 41 is “1”.

  Next, when the response wave from the electronic tag 7B attached to the product 6B is received by the antenna 4, the electronic tag data including the ID code and the product code stored in the electronic tag 7B is read by the electronic tag reader, and the POS It is sent to the terminal 1. Thereby, in the POS terminal 1, it is determined whether or not the electronic tag data including the ID code in the electronic tag data is stored in the electronic tag data buffer 42. If not stored, the electronic tag data is added to the electronic tag data buffer 42. Further, the product name and unit price of the product B are acquired based on the product code in the electronic tag data, and product sales data is generated together with the number of sales and the sales amount. The product sales data is stored in the product item buffer 41. Also, product name, unit price. The number of sales, the sales amount, etc. are displayed on the operator display 19 and the customer display 21. At this time, the total score data N of the merchandise item buffer 41 is “2” when the sales score = 1 is added.

  The same applies when the antenna 4 receives response radio waves from the electronic tags 7C,... Attached to the remaining products 6C,. An example of the registration screen 51 of the operator display 19 at this time is shown in FIG. In this example, a shopper purchases a total of 8 items: 1 product AAA, 1 product BBB, 2 products CCC, 1 product DDD, and 3 products EEE. . At this time, the total score data N of the product item buffer 41 is “8”.

  When the cashier determines from the display content of the registration screen 51 that all the electronic tag data of the customer-purchased merchandise stored in the container 5 has been read, the cashier operates and inputs the closing key 31. Then, as shown in FIG. 8, a message screen 52 for instructing the operator to input the total number of products purchased by the customer is displayed on the operator display 19. On this message screen 52, a score input field 53 is formed. Therefore, the cashier counts the number of commodities accommodated in the container 5 and inputs the numerical value k with the numerical value key 31.

  Then, the numerical value k inputted with this numerical value is compared with the total score data N (in this case, “8”) of the product item buffer 41. Here, if the numerical value k input by the numerical value is “8”, they coincide with each other, so that the tightening process is permitted. Accordingly, the tightening process is performed based on the product sales data of each product 6A, 6B, 6C,... Stored in the product item buffer 41. After the tightening process, the product item buffer 41 is cleared. Thus, accounting for the next customer becomes possible.

  On the other hand, if the numerical value k input by the number does not match the total score data N, for example, if the numerical value k is smaller, the cashier counts with respect to the number N of product tags read by the electronic tag reader 2. Since the number of products k is small and there is a high possibility that the product is miscounted, as shown in FIG. 9, a message screen 54 for instructing the operator to re-enter the total number of products purchased by the customer is displayed on the operator display 19. Is displayed. Also on this message screen 54, a score input field 55 is formed. In this case, the cashier will deal with this by counting the number of products stored in the container 5 and inputting the numerical value k with the numerical keys 31. If the re-input numerical value k matches the total score data, the tightening process is performed.

  On the other hand, when the numerical value k is larger than the total score data N, the electronic tag data may not be read or the electronic tag may be broken due to the influence of the overlap of the electronic tags or noise. Therefore, as shown in FIG. 10, a message screen 56 for notifying the operator of an electronic tag reading error is displayed on the operator display 19. In this case, the cashier operates the clear key to delete the message screen 56 and then collates the contents of the product displayed on the registration screen 51 with the customer purchased product actually stored in the container 5. To find a product whose electronic tag data has not been read. If a corresponding product is found, the sales data of this product may be additionally inputted by, for example, a key operation.

  In addition, the product item buffer 41 is cleared after the closing process. Thus, accounting for the next customer becomes possible. However, at this time, the electronic tag data buffer 42 is not cleared, and the electronic tag data of the electronic tags 7A, 7B, 7C,... Attached to the products 6A, 6B, 6C,. It remains in memory. For this reason, even if the purchased product of the customer immediately before the settlement is close to the electronic tag reader 2, the electronic tag data attached to the product is discarded. Therefore, the accounting process for the next customer can be executed smoothly.

  Thus, in the present embodiment, the POS terminal 1 counts the number of electronic tags whose data has been read by the electronic tag reader 2. The POS terminal 1 also accepts an input of the number of products sold as one commercial transaction. Then, the POS terminal 1 compares the input score and the counted number of electronic tags, and if they match, it settles the price of the product sold as one commercial transaction. Therefore, only when the number of products placed on the tag antenna plate 3 and whose electronic tag data is collectively read by the electronic tag reader 2 is equal to the number of customer-purchased products counted by the cashier itself, Since settlement of commercial transactions with customers is permitted, commercial transactions can be confirmed without mistakes. In this case, a device such as a measuring instrument for measuring the total weight of the product is unnecessary, and there is no trouble of setting unit weight data of each product in the product database. Therefore, an efficient product sales data processing function can be realized with a simple and inexpensive configuration.

The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
For example, in the above embodiment, the point input of the product sold as one commercial transaction is accepted in response to the operation input of the closing key 32. However, as another embodiment, following the process of ST12 of FIG. 5, ST22 of FIG. If the numerical data k is not input, the program may be configured to return to ST2 in FIG. In this case, the cashier places the customer's purchased product on the tag antenna plate 3, then counts the number of the customer's purchased product, and inputs the number with the number keys 31. By doing this, the electronic tag data of all the customer-purchased products placed on the tag antenna plate 3 are read, and when the total score N matches the input score k, the tightening process is immediately executed. As a result, the processing efficiency can be improved.

  Further, in the above-described other embodiments, when numerical data is not input and the tightening key 32 is operated and input, the tightening process may be executed unconditionally. For example, when it is clear that all electronic tag data has been read from the display contents of the operator display 19 such as one or two points of purchase, it is possible to eliminate the need to input numerical data. It is.

  In the embodiment, as a process of determining whether or not the same data as the received electronic tag data is stored in the electronic tag data buffer 42, the ID code unique to the tag included in the received electronic tag data is used. The electronic tag data buffer 42 is searched and the presence / absence of electronic tag data including the same ID code is determined. In the case where the electronic tag read by the electronic tag reader 2 is limited to the product tag, The electronic tag data buffer 42 may be searched with the ID code and product code included in the received electronic tag data, and the presence or absence of electronic tag data including the same ID code and product code may be determined.

  In this embodiment, the case where a program for realizing the function for carrying out the invention is recorded in advance in the apparatus has been described. However, the present invention is not limited to this, and a similar program may be downloaded from the network to the apparatus. A similar program stored in a recording medium may be installed in the apparatus. The recording medium may be any form as long as the recording medium can store the program and can be read by the apparatus, such as a CD-ROM. In addition, the function obtained by installing or downloading in advance may be realized in cooperation with an OS (operating system) inside the apparatus.
