Description

  The present invention relates to a merchandise sales data processing apparatus such as a POS (Point Of Sales) terminal that acquires a merchandise identification code of a merchandise from a medium such as a barcode or a wireless tag attached to the merchandise and processes the merchandise sales data.

  In a conventional POS system, a bar code method is generally adopted. In this method, a bar code representing a product identification code unique to the product is attached to each product, and a barcode scanner is connected to the POS terminal, and the barcode of the product purchased by the customer is read via the barcode scanner. The POS terminal obtains a merchandise identification code from the bar code, and registers the sales data of the merchandise identified by the merchandise identification code.

  On the other hand, in recent years, adoption of a wireless tag system has been studied. This method attaches a wireless tag to each product and stores product information such as a product identification code in its memory, and connects a POS terminal to a wireless tag reader, which allows customers to purchase products via the wireless tag reader. When the product information is read from the attached wireless tag, the POS terminal obtains a product identification code from the product information, and registers the sales data of the product identified by the product identification code.

  In the case of the barcode method, it is necessary to read the barcode attached to the product one by one. However, in the case of the wireless tag method, since the wireless tags of a plurality of products can be read at one time, The processing time required for accounting can be greatly shortened.

  However, since it is extremely difficult to change the product sales method so that all products are sold with wireless tags attached, for cost reasons, products and barcodes with wireless tags are added during the transition period. It is expected that products with a mark will be sold together. For this reason, a merchandise sales data processing apparatus such as a POS terminal capable of supporting not only the wireless tag system but also the barcode system has been proposed (see, for example, Patent Document 1).

  The product sales data processing device that can handle both the conventional barcode method and the wireless tag method is to identify the product after obtaining the product identification code from the barcode read by the barcode scanner and from the wireless tag data read by the wireless tag reader. The processing at the POS terminal after obtaining the code was common. For this reason, in the POS terminal, the product name, unit price, number of sales points, amount of money, etc. of the product sales data registered based on the product identification code are displayed on the display unit. It was not possible to distinguish whether the registration processing was performed by the method or the wireless tag method.

  In general, a product with a wireless tag is registered by a wireless tag method. However, since the wireless tag is an electronic component, the wireless tag data cannot be read if it is broken. In such a case, since a barcode is usually attached to a product attached with a wireless tag, registration processing is performed by a barcode method.

  However, since the customer or operator could not distinguish whether the product was registered by the barcode method or the wireless tag method from the contents displayed on the display unit of the POS terminal. There was a risk of anxiety that the same product had been registered twice by the wireless tag method and the barcode method.

  The present invention has been made based on such circumstances. The purpose of the present invention is to make it possible for the user to identify the difference in the product identification code input method from the display of the product sales data registered based on the product identification code. It is an object of the present invention to provide a product sales data processing apparatus that prevents double registration and registration omission of the same product by distinguishing.

The present invention provides, for example, a first medium attached to a product in a product sales data processing apparatus such as a POS terminal that acquires the sales data of the product identified by the code by inputting the product identification code and displays the sales data on the display unit. For example, a first reading unit that reads a product identification code from a barcode, for example, a barcode scanner, and a second reading unit that reads a product identification code from a second medium attached to the product, such as a wireless tag, such as a wireless tag reader, A reading discriminating means for discriminating whether the inputted product identification code is a code read by the first reading means or a code read by the second reading means; From the merchandise sales data obtained from the merchandise identification code determined to be read and the merchandise identification code determined to be read by the second reading means Product display control means for distinguishing and displaying the received product sales data on the display unit, and the sales score of the product sales data is obtained for each product from the product identification code determined to have been read by the first reading means. A score that is divided into a first score that is the score of the product sales data and a second score that is the score of the product sales data obtained from the product identification code determined to be read by the second reading means And a counting means. The product display control means displays a display row having at least the first and second columns on the screen of the display unit, and displays the first score in the first column on the same display row for the same product. In addition, the second score is displayed in the second column .
The present invention includes a first reading unit that reads a product identification code from a first medium attached to a product, such as a barcode, for example, a barcode scanner, and a second medium attached to the product, such as a product identification code from a wireless tag. Product sales data processing device such as a POS terminal, for example, which has a second reading means for reading the product, for example, a wireless tag reader, and obtains the sales data of the product identified by the code by the input of the product identification code And a reading discriminating means for discriminating whether the inputted product identification code is a code read by the first reading means or a code read by the second reading means, and the reading reading means for the first reading From the merchandise sales data obtained from the merchandise identification code determined to be read by the means and the merchandise identification code determined to be read by the second reading means Product display control means for distinguishing and displaying the received product sales data on the display unit, and the sales score of the product sales data is obtained for each product from the product identification code determined to have been read by the first reading means. A score that is divided into a first score that is the score of the product sales data and a second score that is the score of the product sales data obtained from the product identification code determined to be read by the second reading means It is a program that functions as counting means. The product display control means displays a display row having at least the first and second columns on the screen of the display unit, and displays the first score in the first column on the same display row for the same product. And the second score is displayed in a second column.

  According to the present invention in which such a measure is taken, the user can distinguish the difference in the product identification code input method from the display of the product sales data registered based on the product identification code. The effect which can prevent registration and registration omission is produced.

Hereinafter, the best mode for carrying out the present invention will be described.
In this embodiment, the present invention is applied to a POS terminal that supports both the barcode method and the wireless tag method.

  FIG. 1 is a block diagram showing a main configuration of a POS terminal according to the present embodiment. The POS terminal is equipped with a POS control unit 1 composed of a CPU, ROM, RAM and the like. The POS control unit 1 includes a keyboard 2, a barcode scanner 3, a wireless tag reader 4, a printer 5, controllers 8 to 13 for various input / output devices of an operator display 6 and a customer display 7, and a communication interface 14. And connected.

  The keyboard 2 is provided with various keys necessary for merchandise sales registration such as numeric keys, subtotal keys, and registration lock keys. The barcode scanner 3 optically operates the barcode 21 attached to the product and reads it. The wireless tag reader 4 reads data stored in the memory of the wireless tag 22 attached to the product in a non-contact manner using wireless. The printer 5 performs receipt printing and the like. The operator display 6 displays merchandise sales data, transaction total data, and the like to an operator of a POS terminal called a cashier. The customer display 7 displays merchandise sales data, transaction total data, and the like for shoppers.

  The POS terminal is equipped with a product file 30. As shown in FIG. 2, the merchandise file 30 is preset with merchandise data such as a merchandise name and unit price corresponding to a merchandise identification code (hereinafter referred to as merchandise code) for identifying each merchandise. When a product code is input, the POS control unit 1 searches the product file 30 and takes in product data corresponding to the product code, and registers product sales data based on the product data. . The product file 30 is not installed in the POS terminal but installed in an external computer connected via the communication interface 14 so that the POS control unit 1 accesses the product file 30 via the communication interface 14. Also good.

  As a method of inputting the product code to the POS control unit 1, the product code is input from the barcode method of inputting the product code from the barcode read by the barcode scanner 3 and the memory data of the wireless tag 22 read by the wireless tag reader 4. There is a wireless tag system to input. The POS terminal of the present embodiment is compatible with two systems, a barcode system and a wireless tag system.

  That is, the barcode 21 attached to the product includes a product code for identifying the product. When the barcode 21 is scanned and read by the barcode scanner 3, the barcode data is sent to the scanner controller 9. The scanner controller 9 that has captured the barcode data analyzes the barcode data to obtain a product code. Then, as shown in FIG. 3, a predetermined identifier F0 is attached to the acquired product code and given to the POS control unit 1.

  The wireless tag 22 attached to the product stores at least a product code for identifying the product in the memory. When the wireless tag reader 4 reads the memory data of the wireless tag 22, the wireless tag data is sent to the tag reader controller 10. The tag reader controller 10 that has received the wireless tag data analyzes the wireless tag data and obtains a product code. Then, as shown in FIG. 4, a predetermined identifier F <b> 1 is attached to the acquired product code and given to the POS control unit 1.

  Here, the barcode scanner 3 and the scanner controller 9 constitute first reading means for reading the product code from the first medium attached to the product, that is, the barcode 21. The wireless tag reader 4 and the tag reader controller 10 constitute second reading means for reading the product code from the second medium attached to the product, that is, the wireless tag 22.

  Incidentally, the above-described functions of the scanner controller 9 and the tag reader controller 10, that is, the function of giving different identifiers F0 and F1 to the product code and giving them to the POS control unit 1 are realized by driver software. The wireless tag reader 4 may be a wireless tag reader / writer that can write data to the wireless tag 22 in a contactless manner.

In the POS terminal having such a configuration, the product registration table 40 shown in FIG. 5 and the display mode setting table 50 shown in FIG. 6 are formed in the memory area built in the POS control unit 1.
The merchandise registration table 40 stores merchandise sales data including merchandise codes, merchandise names, unit prices, sales points, and amounts of merchandise purchased by one customer, and total data of sales points and amounts. The storage area for the sales points is divided into three areas of points A, B and C. The score area A is an area for storing the total score of the product read by the barcode scanner 3 and the product read by the wireless tag reader 4. The score area B is an area for storing a total score of products read by the barcode scanner 3. The score area C is an area for storing a total score of products read by the wireless tag reader 4.

  The display mode setting table 50 stores a product display mode M for specifying the product sales data display format for the product registration screens of the operator display 6 and the customer display 7. The product display mode M includes a standard mode specified by data “0”, an area division mode specified by data “1”, a color division mode specified by data “2”, and data “3”. There are four identified number division modes. The display format of each mode will be described later.

  In the display mode setting table 50, a user (store side) of the POS terminal can set a desired product display mode M. First, the procedure for setting the product display mode M will be described with reference to the flowchart of FIG.

  When the power is turned on, the POS terminal enters an idle state in which various business menus can be selected. In this idle state, the user operates the keyboard 2 to select a product display mode setting job. Then, the POS control unit 1 starts processing shown in the flowchart of FIG.

  First, when it is confirmed that the product display mode setting job has been selected as ST (step) 1, it waits for the numerical value n to be entered as ST2. Then, when the numerical value n is entered by the numeric keys of the keyboard 2, it is determined whether or not the numerical value n is any one of 0 to 3 effective as the product display mode M. Here, when the numerical value n is other than 0 to 3, the key input is regarded as an error.

  When the numerical value n is any of 0 to 3, the POS control unit 1 stores the numerical value as the product display mode M in the display mode setting table 50 as ST4. Thus, the POS terminal returns to the idle state.

  Therefore, the user sets the numerical value “0” when the standard mode is set as the product display mode M, the numerical value “1” when the area division mode is set, and the numerical value “0” when the color division mode is set. In order to set the number dividing mode to “2”, the numerical value “3” may be entered as a numerical value.

  Next, a procedure for registering a product purchased by one customer will be described with reference to the flowchart of FIG. A store clerk who performs a registration operation, a so-called cashier, operates the keyboard 2 of the POS terminal in an idle state to select a product registration service. Then, the POS control unit 1 starts the process shown in the flowchart of FIG.

  That is, the POS control unit 1 waits for a product code to be input as ST11. When the product code is input, it is determined whether a registration flag is set or not in ST12. The registration flag is information for identifying whether or not registration of a product purchased by one customer has started. Since it is reset at the time of registration of the first item, the POS control unit 1 initializes the product registration table 40 as ST13. In ST14, a registration flag is set. Since it is set at the time of registration after the second point, the POS control unit 1 does not execute the processes of ST13 and ST14.

  If the registration flag is set in ST14 or has already been set in ST12, the POS control unit 1 searches the product file 30 with the product code input as ST15. Then, the product data such as the product name and unit price stored in correspondence with the product code is fetched.

  Next, the POS control unit 1 searches the product registration table 40 using the product code input as ST16. Then, in ST17, it is determined whether or not the same product code is stored in the product registration table 40. If not stored, the POS control unit 1 stores the input product code and the product name and unit price imported from the product file 30 in association with the same table number (No) as ST18. If stored, the POS control unit 1 does not execute the process of ST18.

  Next, the POS control unit 1 determines an identifier added to the product code input as ST19 (reading determination unit).

  Here, when the identifier is F0, since the input product code is a code read by the barcode scanner 3, the POS control unit 1 stores the input product code in the product registration table 40 as ST20. The score of the registered product is added to the score A area and the score B area of the table number. On the other hand, when the identifier is F1, since the input product code is a code read by the wireless tag reader 4, the POS control unit 1 stores the input product code in the product registration table 40 as ST21. The score of the registered product is added to the score A area and the score C area of the table number (score counting means).

  Note that the score of the registered product is the numerical value when numeric data is entered via the keyboard 2 immediately before the product code is input, and is “1” when the numeric data is not entered.

  Next, the POS control unit 1 calculates the amount data by multiplying the unit price data and the score A for each table number of the product registration table 40 as ST22, and stores it in the amount area of the same table number. Further, as ST23, for each area of the points A to C and the amount of money in the product registration table 40, the sum of the numerical values in the area is calculated and stored in each total area.

  Thereafter, the POS control unit 1 executes product information display processing for the operator display 6 and the customer display 7 in ST24 (product display control means). This product information display process will be described later.

  When the merchandise information display process ends, the POS control unit 1 determines whether or not a closing input has been made in ST25. When the cashier finishes registering the product purchased by the customer, the cashier presses the registration lock key on the keyboard 2. If it is determined that there is no closing input, the POS control unit 1 returns to ST11 and waits for the next product code to be input.

  If there is a closing input, the POS control unit 1 executes a registration closing process such as payment settlement and receipt issuance in ST26. When this registration closing process is completed, the POS control unit 1 resets the registration flag in ST27 and returns to the idle state.

  The merchandise information display process will be described with reference to the flowchart of FIG. That is, when entering the product information display process, the POS control unit 1 checks the product display mode M set in the display mode setting table 50.

  When the product display mode M is “0”, that is, when the standard mode is set (YES in ST31), the POS control unit 1 sets the product name, the unit price, the score A and the order from the product registration table 40 in the order of the table number as ST32. While reading each data of the amount, the total data of the point A area and the total data of the amount area are read. And these data are displayed on each registration screen of the display 6 for operators and the display 7 for customers.

  When the product display mode M is “1”, that is, when the area division mode is set (YES in ST33), the POS control unit 1 searches the product registration table 40 in ST34 and has a score B of 1 or more. The product name, unit price and score B are read from the number area. Then, these data are displayed in the left area of each registration screen of the operator display 6 and the customer display 7. In ST35, the product registration table 40 is searched to read the product name, unit price, and score C from the table number area where the score C is 1 or more. And these data are displayed on the right area in each registration screen of the display 6 for operators and the display 7 for customers. Further, in ST36, the total data of the point A area and the total data of the amount area are read from the product registration table 40. And these data are displayed on the lowest line in each registration screen of the display 6 for operators and the display 7 for customers.

  When the product display mode M is “2”, that is, when the color division mode is set (YES in ST37), the POS control unit 1 in ST38 from the product registration table 40 in the order of the table number, product name, unit price, score A And the total amount data and the total amount area data are read out. And these data are displayed on each registration screen of the display 6 for operators and the display 7 for customers. At this time, the character display color is set to the first color (black) for the product name, unit price, point A, and amount data read from the table number area with a score B of 0 in ST39. For the product name, unit price, score A, and amount data read from the table number area with a score of 0, the character display color is the second color (blue). The character display color is the third color (red) for each of the product name, unit price, score A, and amount data read from the table number area where the scores B and C are both 1 or more.

  When the product display mode M is “3”, that is, when the number division mode is set (NO in ST37), the POS control unit 1 sets the product name, unit price, and score A in order of the table number from the product registration table 40 as ST40. , Score B, score C, and amount data are read out, and the total data of the point A area, the point B area, and the point C area and the sum data of the amount area are read out. And these data are displayed on each registration screen of the display 6 for operators and the display 7 for customers.

  Now, one customer has 10 items [AAAAA] with a unit price of 1,000 yen, 9 items [BBBB] with a unit price 2,000 yen, and 8 items [CCCC] with a unit price 3,000 yen. An example of point purchase is illustrated. Here, it is assumed that the product [AAAA] and the product [BBBB] have both the barcode 21 and the wireless tag 22 attached thereto, and the product [CCCC] has only the barcode 21 attached thereto. However, the wireless tag 22 attached to any one of the nine points of the product [BBBB] is assumed to be broken.

  In this case, first, the cashier registers 10 items [AAAA] and 9 items [BBBB] by collectively reading the data of the wireless tag 22 attached to each of them, and the product [CCCC] ] 8 points are registered by causing the scanner 3 to read the barcode 21 attached to one arbitrarily extracted product [CCCC] after placing the numerical value “8”. Note that eight items [CCCC] may be registered by causing the scanner 3 to read the barcode 21 one by one.

  At this time, despite the fact that there are 9 items [BBBB], the display of the registered score is 8 points, so the cashier has the wireless tag 22 attached to any one item of the product [BBBB]. Recognized as broken.

  In that case, since all the product codes for the product [BBBB] are common, one point is arbitrarily extracted from the product [BBBB], and the barcode 21 attached to the product [BBBB] is read by the scanner 3. Register by. By doing so, the registration of all 27 points purchased by the customer is completed.

  Now, at the time when the registration of 27 points is completed, examples of display screens of the operator display 6 and the customer display 7 when the product display mode M is “0”, that is, the standard mode is set are shown in FIG. Shown in FIG. 11 shows an example of a display screen when the product display mode M is “1”, that is, the area division mode is set. FIG. 11 shows a case where the product display mode M is “2”, that is, the color division mode is set. FIG. 12 shows an example of the display screen, and FIG. 13 shows an example of the display screen when the product display mode M is “3”, that is, the number division mode is set.

  The standard mode shown in FIG. 10 is a conventional pattern. As is apparent from the figure, it is unclear whether each product is registered by the barcode method or by the wireless tag method.

  On the other hand, the area division mode shown in the screen example in FIG. 11 is the first pattern according to the present invention. In this display pattern, 10 items [AAAA] and 8 items [BBBB] are registered by the wireless tag method, and 1 item [BBBB] and 8 items [CCCC] are registered by the barcode method. You can see at a glance.

  Further, the color division mode shown in FIG. 12 is a second pattern according to the present invention. With this display pattern, all products [AAAA] with black text color are registered with the wireless tag system, and all products with blue text color [CCCC] are registered with the barcode system. It can be seen that [BBBB], whose color is red, has been registered in 9 points by the barcode method and the wireless tag method. In this case, although the number of points registered by the barcode method and the wireless tag method is not known, it is possible to easily determine which product is registered by which method.

  Next, the number division mode shown in the screen example in FIG. 13 is a third pattern according to the present invention. With this display pattern, all 10 items of merchandise [AAAAA] are registered by the wireless tag method, one of 9 items of merchandise [BBBB] is registered by the barcode method, and the remaining 8 points are wireless. It can be seen at a glance that all the 8 items of merchandise [CCCC] are registered by the barcode method.

  As described above, according to the present embodiment, whether the product is registered by the barcode method or the wireless tag method by selecting the region division mode, the color division mode or the number division mode as the product display mode. Can be easily identified by cashiers and customers. Therefore, for example, when the same product is registered again by the barcode method because the wireless tag 22 is broken, the display contents of the product registered by the wireless tag method and the product registered by the barcode method are distinguished. So it can be clarified that it is not double registration. Also, no registration omissions occur.

  In particular, by selecting the area division mode or the number division mode, the number of points registered by the barcode method and the number of points registered by the wireless tag method are clarified.

  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-described embodiment, the present invention is applied to a product sales data processing apparatus that supports two product code reading methods, that is, a barcode method and a wireless tag method, but the product code reading method is limited to the above two methods. It is not a thing. Further, it may be compatible with three or more product code reading methods.

  Further, in the above embodiment, when the product display mode M is “2”, the color of the display character is changed between a product using only the barcode method, a product using only the wireless tag method, and a product using both methods. However, instead of changing the character processing, other character attributes such as character size and character modification may be changed.

  Further, in the above-described embodiment, the case where the product display mode has the three modes of the area division mode, the color division mode, and the number division mode in addition to the standard mode has been described. However, at least one mode among these three modes is shown. As long as you have.

  In the above embodiment, the screens displayed on the operator display 6 and the customer display 7 are the same. However, the display mode setting table 50 includes the product display mode area and the customer display area for the operator display 6. The display is divided into product display mode areas for the display 7 for use, and any product display mode can be set for each, so that the contents of the screen are different between the display 6 for the operator and the display 7 for the customer. May be.

In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
