Description

  The present invention relates to a merchandise sales data processing apparatus such as an electronic cash register and a POS (Point Of Sales) terminal.

  Generally, this type of merchandise sales data processing apparatus has a keyboard and a scanner as data input means, and is provided with an operator display and a customer display as display means. Then, when a code for identifying the sales product is input via the input means, product data such as the product name, unit price, department, tax classification, etc. of the sales product set in association with the code is acquired. Sales data such as the number of sales and the sales amount is registered based on the product data, and the product data and the sales data are displayed on each display for operators and customers.

However, the screen size of the display is currently below the SVGA (Super Video Graphics Array) specification due to installation space and price factors, and there is a limit to reducing the character size considering the operator's visibility. It is impossible to display all items of product data and sales data on one screen. For this reason, conventionally, displaying the product name, unit price, number of sales points, sales price, tax classification, etc. on one screen and displaying both the product name and code with a large number of characters on one screen is a matter of screen size and character size. The actual situation was not performed due to restrictions (see, for example, Patent Document 1).
JP 2004-234572 A

  As described above, in the conventional merchandise sales data processing apparatus of this type, since the screen size and the character size of the display unit are limited, only the data of items set in advance among the merchandise data and the merchandise sales data is displayed on the screen. Could not be displayed. In particular, since the items “product name” and “code” both have a large number of characters, it is difficult to set both as display items. For this reason, since anyone can specify a product by displaying the product name, the item “product name” is the display item and the item “code” is the non-display item.

  However, depending on the user, the product name may not be set in detail, but may be set in units of groups such as magazines, weekly magazines, gums, and chocolates. In such a case, since the same product name may be set even for different products, there is a problem that it is difficult to specify the product only by displaying the product name.

  The present invention has been made based on such circumstances, and the object of the present invention is to display information related to more items within the limited screen size of the display unit, and from the display information to the product. It is an object of the present invention to provide a merchandise sales data processing apparatus that can reliably identify a product.

  The present invention has a code input means for specifying a sales product. When a code is input, the product name, unit price, etc. of the sales product set in association with the code are acquired. In a merchandise sales data processing apparatus that processes merchandise sales data based on merchandise data such as unit price, a display section capable of displaying a screen having a display area for product data, and a display area of the screen displayed on the display section Operation detection means for detecting that an instruction operation has been performed, display item switching means for switching an item of product data to be displayed in the display area every time it is detected that the display area has been instructed by the operation detection means, and product data The screen editing means for extracting the data of items to be displayed in the display area and editing the screen, and the screen edited by the screen editing means are displayed on the display section. Is obtained by a that the display control means.

  According to the present invention in which such measures are taken, it is possible to display information regarding more items, particularly items necessary for specifying a product, within a limited screen size of the display unit, and the product can be reliably identified from the display information. It is possible to provide a merchandise sales data processing apparatus that can be specified as follows.

The best mode for carrying out the present invention will be described below with reference to the drawings.
This embodiment is a case where the present invention is applied to a POS terminal which is an aspect of a merchandise sales data processing apparatus.

  FIG. 1 is a perspective view showing an external configuration of the POS terminal 1. The POS terminal 1 is equipped with a keyboard 2, an operator display 3, a customer display 4, and a printer 5 for receipt and journal printing. Moreover, the drawer 6 for accommodating cash etc. is formed.

  The operator display 3 is an SVGA TFT (Thin Film Transistor) liquid crystal display, and a touch panel 7 is laminated on the display surface. The operator display 3 displays a registration screen 30 laid out as shown in FIG. 2 when processing the merchandise sales data. This registration screen 30 includes a registration details area 31 that displays a list of product names, department codes, unit prices, sales points, sales amounts, and tax classifications of products sold as one commercial transaction, and products for which product codes have been input immediately before. Registered product area 32 that displays the product name, tax classification, department code, unit price, sales points, and sales amount of each item, and the number of sales points, discount total, subtotal amount, external tax amount, billing amount, deposit amount, and change in one commerce transaction An accounting information area 33 for displaying the amount is formed.

In the present embodiment, as shown in FIG. 2, the product name, tax classification, department code and unit price, which are the product data of the product for which the product code has been input immediately before, and the points and the amount of sales data are registered products. When the inside of the registered product area 32 is touched while displayed in the area 32, a product code is displayed instead of the product name as shown in FIG. Further, when the inside of the registered product area 32 is touched with the product code displayed as shown in FIG. 3, the product name is displayed again as shown in FIG.
Hereinafter, a configuration of a main part for realizing such a display switching function will be specifically described.

  FIG. 4 is a block diagram showing the internal configuration of the POS terminal 1. The POS terminal 1 includes a CPU (Central Processing Unit) 11 as a control unit main body. Further, a ROM (Read Only Memory) 12 in which fixed data such as a program executed by the CPU 11 is stored in advance, and a RAM (Random Access Memory) 13 in which various memory areas necessary for processing the merchandise sales data are formed. A clock unit 14 for measuring the current date and time, a scanner interface 15 for taking in barcode data read by a scanner (not shown), a communication controller 16 for controlling data communication with the store server 8, and a keyboard 2 A keyboard controller 17 for capturing operation key signals, a touch panel controller 18 for capturing signals corresponding to touch position coordinates by controlling the touch panel 7, and a first display for displaying product data, sales data, etc. by controlling the operator display 3. The display controller 19 and the customer display 4 to control product data and A second display controller 20 for displaying sales data, a printer controller 21 for controlling the printer 5 to perform receipt printing and journal printing, an I / O port 22 for outputting a signal for opening the drawer 6, and the like. It is installed. The CPU 11, the ROM 12, the RAM 13, the clock unit 14, the scanner interface 15, the communication controller 16, the I / O port 22, and the controllers 17 to 21 of various input / output devices are connected by a bus line 23 such as an address bus and a data bus. Electrically connected.

  The store server 8 stores and stores a product code for specifying each product and product data such as a product name, a unit price, a department code, and a tax classification set in advance associated with the product code. 9 is provided. The POS terminal 1 can acquire arbitrary data of the product file 9 by accessing the store server 8 via a communication line such as a LAN (Local Area Network). The product file 9 may be stored in a storage unit of the POS terminal 1, for example, the RAM 13 or an HDD device (not shown).

  As shown in FIG. 5, the POS terminal 1 having such a configuration has product data (product code, product name, department code, unit price, tax classification) and sales data (sales points) displayed in the registration details area 31 of the registration screen 30. , Sales amount) for each sale product, registration details buffer 51 for storing the same product data and sales data stored in the registered product area 32, and accounting data (in the accounting information area 33). The transaction information buffer 53 for storing the sales points, the total discount amount, the subtotal amount, the external tax amount, the billing amount, the deposit amount and the change amount) is formed in the RAM 13.

  In addition, as shown in FIG. 6, a plurality of screen item patterns can be stored in the RAM 13 corresponding to the position information (upper row 1, upper row 2, lower row 1, lower row 2, lower row 3, lower row 4) of the registered product area 32. An item pattern table 61 and an area of a screen number counter 62 for counting a screen number n for identifying each screen item pattern are formed. In this embodiment, the item “product name” is set for the position information “upper stage 1”, the item “tax classification” is set for the position information “upper stage 2”, and the position information “lower stage 1” is set. The item “department” is set, the item “unit price” is set for the position information “lower 2”, the item “score” is set for the position information “lower 3”, and the position information “lower 4”. The item for the screen item pattern “1” in which the item “amount” is set for the item number and the position information “upper row 1” of the screen item pattern of this screen number “1” is “product code”. A screen item pattern of screen number “2” that is shared with the screen item pattern of screen number “1” is stored.

  Therefore, the CPU 11 controls the display of the registered product area 32 on the registration screen 30 for one commercial transaction according to the procedure shown in the flowchart of FIG. That is, the CPU 11 waits for the first product registration in one commercial transaction as ST (step) 1. When the product code is input by the barcode scanning operation by the scanner or the numeric key operation of the keyboard 2, it is determined that the product is registered, and the registration details buffer 51, the registered product buffer 52 and the accounting information buffer 53 are cleared as ST2. Then, the process proceeds to ST3.

  In ST3, the CPU 11 searches the product file 9 with the input product code, and acquires product data such as product name, unit price, department code, and tax classification set in correspondence with the product code. Then, if the sales amount is calculated by multiplying the unit price by the number of sales points (if a multiplier is entered by key operation immediately before entering the product code, 1 if the multiplier is not entered) The product code, product name, department code, unit price, and tax classification product data and sales data of sales points and sales amount are stored in the registered product buffer 52.

  Next, the CPU 11 initializes the count value n of the screen number counter 62 to “1” as ST4.

  Next, the CPU 11 reads the screen item pattern of the screen number n (n is the count value of the screen number counter 62) from the item pattern table 61 as ST5. If product data and sales data for each item of this screen item pattern are acquired from the registered product buffer 52 as ST6, a registered product area is obtained from the acquired data of each item and position information corresponding to the item as ST7. 32 screen data is edited (screen editing means).

  Thereafter, the CPU 11 displays the screen data of the registered product area 32 edited as ST8 on the registration screen 30 (display control means). In this state, the CPU 11 waits for a touch operation on the registration screen 30 as ST9, a next product registration as ST10, or a registration closing operation as ST11.

  If it is determined that there is a touch operation based on a signal from the touch panel 7 input to the touch panel controller 18, the CPU 11 analyzes the signal as ST12 to check which area of the registration screen 30 is touched. . If it is detected that the inside of the registered product area 32 has been touched (operation detection means), the registered product area 32 is instructed, and the CPU 11 counts up the screen number counter 62 in ST13. As a result, if the count value N of the screen number counter 62 exceeds the maximum screen number N of the screen item pattern stored in the item pattern table 61 as ST14, the process proceeds to ST4, and if not, ST5 The process of ST5 to ST8 is executed again (display item switching means, screen editing means, display control means).

  On the other hand, when the next product registration is performed, the CPU 11 transfers the data in the registered product buffer 52 to the registration details buffer 51 in ST15. Then, in ST16, the registered product buffer 52 is cleared. Thereafter, the process proceeds to the process of ST3, and the processes of ST3 to ST8 are executed again (screen editing means, display control means).

  If the CPU 11 determines that a registration closing operation has been performed based on a signal input to the keyboard controller 17, the CPU 11 transfers the data in the registered product buffer 52 to the registration details buffer 51 in ST17. Thus, the CPU 11 ends the display control of the registered merchandise area 32, and thereafter executes a registration closing process based on the merchandise data and sales data stored in the registration details buffer 51.

  In the POS terminal 1 of the present embodiment configured as described above, when the cashier inputs the product code of the product purchased by the customer by the barcode scanning operation or the numeric key operation, the product code is set corresponding to the product code. Product data such as product name, unit price, department code, tax classification, etc. are retrieved from the product file 9. Then, the sales amount is calculated from the unit price and the sales point in the product data, and the registered product buffer 52 stores the product data, the sales point and the sales amount of the product code, product name, department code, unit price and tax classification. Data is stored.

  Further, the count value n of the screen number counter 62 is initialized to “1”. Thus, the screen data of the registered product area 32 is edited based on the screen item pattern of the screen number 1 and displayed in the registered product area 32 of the registration screen 30. In the present embodiment, the item “product name” is set for the position information “upper 1” as the screen item pattern of the screen number 1, and the item “tax classification” is set for the position information “upper 2”. The item “department” is set for the position information “lower stage 1”, the item “unit price” is set for the position information “lower stage 2”, and the item “score” is set for the position information “lower stage 3”. Since the item “amount” is set for the position information “lower stage 4”, “product A” (product name) and [outside] (outside) ( Tax classification) is displayed, and “001” (department code), “500 yen” (unit price), “1 point” (sales points), and “500 yen” (sales amount) are displayed in the lower part.

  In this state, when the cashier inputs the product code of the next purchased product, the data of the product name, tax classification, department code, unit price, sales point, and sales amount displayed in the registered product area 32 are registered in the registration details area 31. Is displayed on the first line. In the registered merchandise area 32, data of a merchandise name, a tax classification, a department code, a unit price, a sales score, and a sales price of the next purchased merchandise are displayed.

  In the state shown in FIG. 2, when the cashier touches the registered product area 32 with a finger, the count value n of the screen number 62 is counted up to “2”. Thereby, the screen data of the registered product area 32 is edited based on the screen item pattern of the screen number 2 and displayed in the registered product area 32 of the registration screen 30. In the present embodiment, the item “product code” is set for the position information “upper stage 1” as the screen item pattern of the screen number 2, and the screen of the screen number 1 is displayed from the position information “upper stage 2” to “lower stage 4”. Since the same item as the item pattern is set, as shown in FIG. 3, the product name “product A” displayed in the upper part of the registered product area 32 is switched to the product code “4912345679011” of the product.

  In this state, when the cashier inputs the product code of the next purchased product, the product name, tax classification, department code, unit price, sales of the product whose product code is displayed in the registered product area 32 as described above. The score and sales amount data are displayed in the first line of the registration details area 31. In the registered merchandise area 32, data of a merchandise name, a tax classification, a department code, a unit price, a sales score, and a sales price of the next purchased merchandise are displayed.

  In the state shown in FIG. 3, when the cashier touches the registered product area 32 again, the count value n of the screen number 62 is reset to “1”, so the display content of the registered product area 32 is shown in FIG. Return to the state shown.

  As described above, according to the present embodiment, even in the POS terminal 1 having the operator display 3 that cannot display the product name and the product code on one screen due to restrictions on the screen size and the character size, the registered product area The product name and product code of the product registered for sale can be displayed alternately by a simple operation of touching the inside of the product 32 only with a finger. Therefore, even if different products have the same product name and it is difficult to specify the product by simply displaying the product name, it is possible to identify the product by checking the product code. Play.

  The registered product buffer 52 includes not only the data of items displayed in the registered product area 32 among the data of each item acquired from the product file 9 in response to the input of the product code of the product purchased by the customer, The data of the items that are not displayed is also stored, and when there is a display switching instruction, the data of the items that are not displayed is acquired and displayed from the registered product buffer 52. When displaying, it is not necessary to newly search the product file 9 to acquire necessary information. Therefore, the display process can be speeded up.

  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 case where the product name and the product code are alternately switched and displayed by the touch operation in the registered product area 32 has been described, but the product image data of each product is set in the product file 9 and the item The item for the position information “upper stage 1” is set to “product image” in the pattern table 61, and the screen item pattern with the screen number “3” is stored in common with the screen item patterns with the screen numbers “1” and “2” for the other items. Accordingly, it is also possible to switch and display information that can specify a product in the order of product name, product code, product image, and product name by a touch operation in the registered product area 32.

  In addition, by using the same configuration as that of the above-described embodiment in which the product name and the product code are alternately switched and displayed by the touch operation in the registered product area 32, the product name and the product code by the touch operation in the registered specification area 31 are used. It is also possible to configure so that and are alternately displayed. However, since the data of each registered product displayed in the registration details area 31 needs to be able to be selectively deleted or modified within one commerce transaction, the touch operation in the first touch operation It is desirable that the product data in the row is selected and the product name and product code of the product data are alternately switched and displayed by the second and subsequent touch operations.

  In the embodiment, the display data of all display items in the area 32 is switched by touching the registered product area 32 regardless of the touch position. However, the display is performed at the touched position. It is also possible to switch only the display data of the displayed item.

  That is, the screen number counter 62 is a screen number counter 71 having count values n1 to n6 for each position information of the registered product area 32 as shown in FIG. Then, in each processing step ST1 to ST17 shown in the flowchart of FIG. 7, in step ST4, when product registration is performed, all count values n1 to n6 for each position information are initialized to “1”. Further, when the part touch-operated in step ST12 is in the registered product area 32 of the registration screen 30, it is determined which item in the area 32 is touch-operated, and in step ST13 it is determined that the touch operation has been performed. Only the count value nx (1 ≦ x ≦ 6) corresponding to the position information of the item is counted up. In step ST14, it is determined whether or not the count value nx counted up in the process of ST13 exceeds the maximum screen number N of the screen item pattern. If it exceeds, only the count value nx is determined in step ST4. To “1”.

  By changing a part of the configuration as described above, by touching the registered product area 32 where the display data of a plurality of items is displayed, the display data of the item displayed at the touched position is displayed. Can only switch.

  In the above embodiment, the touch panel 7 is arranged on the display surface of the operator display 3 and the indication operation of the display area is detected by detecting the touch operation on the screen. However, a pointing device such as a mouse is connected, The present invention can be applied to a POS terminal that does not have the touch panel 7 by detecting a position where the pointer is clicked by the operation of the pointing device as an instruction operation position in the display area.

  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.
