Description

  The present invention relates to a merchandise sales data processing apparatus such as a POS terminal or a data code scanner, and more particularly to a screen display technique thereof. The present invention also relates to a computer program installed in such a merchandise sales data processing apparatus.

  A code symbol reader having a POS terminal, a data code scanner, and a display with a touch panel, which is a merchandise sales data processing apparatus, has been devised in various ways in the screen configuration of the merchandise registration screen displayed on the display during the merchandise registration business. . During product registration work, it is necessary to repeat the product registration work for one transaction over and over again, so the quality of the product registration screen greatly affects the efficiency of product registration work and the fatigue level of operators. Because it does.

  On the other hand, the screen configuration of the preferred product registration screen differs depending on the type of store that uses the product sales data processing device, for example, the type of mass sales store, supermarket, drug store, convenience store, or the like. Moreover, even if it is the same kind of store, as long as the concept and preference of each store are different, the screen configuration of the product registration screen desired in each store should be different.

  Thus, conventionally, customization of the screen configuration of the product registration screen has been performed. This work is a collaborative development work between the screen designer and the engineer. Specifically, the customization work is to create a screen frame that determines the screen configuration of the product registration screen according to the store's request, and apply various area displays that make up the product registration screen to this screen frame. Made by. The area display in this case is, for example, a total amount area for displaying the total amount, a detailed area for displaying detailed information during product registration, and the like. In such area display, a layout design, a color design, or the like is applied in advance or afterwards according to the screen frame.

  Patent Document 1 describes a method for changing the screen configuration without requiring a steady customization operation as described above.

  FIG. 3 is a schematic diagram showing screen data 201 to be displayed on the operator display 15 of the POS terminal 11 and the display 106 of the code symbol reader 101. The screen data 201 includes frame data 202, area data 203, display position designation data 204, and position specifying data 205.

  The frame data 202 is one screen of the product registration screen RS (see FIGS. 6 and 8) displayed on the operator display 15 and the display 106 in the POS terminal 11 and the code symbol reading device 101 during the product registration process. Region oa is defined. This one-screen area oa is defined by a size that is an integral multiple of the minimum area ma, which is an area in which a touch designation operation can be performed on the touch panel TP of the operator display 15 and the touch panel 105 of the display 106. In FIG. 3, the minimum area ma is shown as an area surrounded by virtual grid lines shown in one screen area oa. Such one screen area oa is defined by coordinate point (x, y) or the like in the frame data 202.

  Here, as an example, the minimum area ma in one screen area oa shown in FIG. 3 is not set as data in the frame data 202, but is only shown virtually.

  As another example, the minimum area ma may be included as actual data in one screen area oa. In this case, as an example, the position of the minimum area ma can be defined by coordinate points (x, y) that define the four corners of the minimum area ma. As another example, the position of the minimum area ma can also be defined by coordinate points (x, y) that define two corners located on the diagonal line of the minimum area ma. An ID number is set for each minimum area ma thus defined.

  The area data 203 constitutes an area display AU in which common elements that are part of the product registration screen RS are gathered, and is unitized by combining the minimum area ma in an integral multiple. The minimum area ma in this case is not virtual but data itself. The data in this case is defined by vertical and horizontal sizes. Here, “area display AU as part of product registration screen RS” means title area AU1, current area AU2, total amount area AU3, single item display area AU4, category display area AU5, detail display area (full AU6, detail display area (simple) AU7, function key shortcut AU8, search key AU9, etc. (see FIG. 4). Further, “common elements” that collectively form an area display AU are, for the title area AU1, a business content name, a responsible company name, a date, and the like. In the case of the current area AU2, the item name, unit price, number of points, etc. of the current item for which the item code is input. In the case of the total amount area AU3, the total amount, points, and the like. In the case of the single item display area AU4, it is a single item display (text + image) of the product. In the case of the category display area AU5, the category classification of the products displayed in the single item display area AU4 is, for example, sale items, vegetables, fruits, prepared foods, fresh fish, meat, alcoholic beverages, members, etc. In the case of the detail display area (full) AU6, it is a full display of the history information of the product for which the product code is input. In the case of the detail display area (simple) AU7, it is a simplified display of the history information of the product for which the product code is input. In the case of the function key shortcut AU8, these are various function keys. In the case of the search key AU9, search keywords (acronyms) such as “A”, “KA”, “SA”, “TA”, “NA”,. As an example, the search key AU9 causes only the products belonging to the category of the search keyword (acronym) to be listed in the single item display area AU4.

  The display position designation data 204 is data that designates the display position of the area display AU constituted by the area data 203 in one screen area oa defined by the frame data 202.

  As an example, the display position designation data 204 is defined as a coordinate point (x, y) in one screen area oa defined for each area display AU. For example, the coordinate point (x, y) of the upper left corner of the virtual grid in one screen area oa is defined, and the upper left corner of each area display AU is aligned with the position of this coordinate point (x, y). The data is processed.

  As another example, if it is assumed that the minimum area ma is included as actual data in one screen area oa in the frame data 202 and an ID number is set for each minimum area ma, The position designation data 204 may be defined as the ID number of the minimum area ma defined for each area display AU.

  The position specifying data 205 is data for specifying the position of each element in the area display AU that can be touch-designated by the touch panel TP of the POS terminal 11 and the touch panel 105 of the code symbol reading device 101 included in the area data 203. .

  As an example, the position specifying data 205 is defined as a range of coordinate points (x, y) in one screen area oa defined by the frame data 202 defined for each element in each area display AU. . The range of the coordinate point (x, y) is defined as, for example, a coordinate point (x, y) at four corners, and is defined as a coordinate point (x, y) at two corners located on a diagonal line as another example. Yes.

  As another example, if it is assumed that the minimum area ma is included as actual data in one screen area oa in the frame data 202 and an ID number is set for each minimum area ma, The specific data 205 may be defined as an ID number of the minimum area ma defined for each element in each area display AU. In this case, the specified number of ID numbers of the minimum area ma varies depending on the number of minimum areas ma occupied by such elements. For example, if the display area of the element occupies two minimum areas ma, the ID number of the specified minimum area ma is also two.

  FIG. 4 is a schematic diagram illustrating a display method of the product registration screen RS based on the screen data 201. On the display surface 15 a of the operator display 15 of the POS terminal 11 and the display surface 106 a of the display 106 of the code symbol reader 101, an area display according to the display position designation data 204 is displayed in one screen area oa defined by the screen data 201. The AU is inserted and displayed as a product registration screen RS. As the area display AU, for example, title area AU1, current area AU2, total amount area AU3, single item display area AU4, category display area AU5, detail display area (full) AU6, detail display area (simple) AU7, function key shortcut AU8, search key AU9, etc. are prepared. The “common elements” that collectively form the area display AU are as described above, and the contents thereof are illustrated in FIG.

  FIG. 5 is a flowchart showing a flow of display processing of the commodity registration screen RS on the display surface 15a of the operator display 15 of the POS terminal 11 and the display surface 106a of the display 106 of the code symbol reader 101. This processing is executed in the POS terminal 11 according to the computer program copied by the CPU 51 to the RAM 53, and in the code symbol reader 101, the CPU 161 executes it according to the computer program recorded as firmware in the ROM 162.

  The CPU 51 of the POS terminal 11 and the CPU 161 of the code symbol reader 101 call the frame data 202 stored in the screen data 201 from the storage units (the RAM 53 of the POS terminal 11 and the ROM 162 of the code symbol reader 101), respectively ( Step S1). Subsequently, area data 203 constituting a plurality of types of area display AUs that are part of the product registration screen RS is called from the storage unit (step S2). Subsequently, display position designation data 204 is called from the storage unit (step S3). In this case, when the area data 203 and the display position designation data 204 are described in an integral manner, the processes of step S2 and step S3 are integrated. The display position designation data 204 thus called is data for designating the display position of the area display AU constituted by the area data 203 in one screen area oa defined by the frame data 202. Therefore, according to the called display position designation data 204, the area display AU constituted by the area data 203 is applied to one screen area oa defined by the frame data 202, the operator display 15 of the POS terminal 11, the code symbol, The registration screen RS is displayed on the display 106 of the reading apparatus 101 (step S4).

  Next, the CPU 51 of the POS terminal 11 and the CPU 161 of the code symbol reader 101 are on standby for determining whether or not there is a touch designation on the touch panel TP of the POS terminal 11 and the touch panel 105 of the code symbol reader 101 (step S5). . If it is determined that there is a touch designation during this determination standby (Y in step S5), the area specifying data 205 stored in the storage unit (the RAM 53 of the POS terminal 11 and the ROM 162 of the code symbol reader 101) is referred to, and the area data A recognition process is executed as to which element in the area display AU constituted by 203 is touch-designated (step S6). Since the position specifying data 205 specifies the position of each element in the area display AU constituted by the area data 203, the position specifying data 205 is referenced to recognize which element is touch-designated. It becomes possible.

  Thereafter, the CPU 51 of the POS terminal 11 and the CPU 161 of the code symbol reading apparatus 101 repeat the processing of step S5 to step S6 until determining the input of the end command, respectively, and determining the input of the end command (Y of step S7). The process is terminated.

  FIG. 6A is a schematic diagram showing an example of a product registration screen RS displayed on the operator display 15 of the POS terminal 11, and FIG. 6B is displayed on the display 106 of the code symbol reader 101. It is a schematic diagram which shows an example of the registration screen RS of goods.

  As shown in FIG. 6 (a), in the product registration screen RS displayed on the operator display 15 of the POS terminal 11, the title area AU1 from the top in one screen area oa defined by the frame data 202, The individual area displays AU are arranged in the order of category display area AU5, detail display area (full) AU6, total amount area AU3, and function key shortcut AU8.

  As shown in FIG. 6B, in the product registration screen RS displayed on the display 106 of the code symbol reader 101, the title area AU1, category, from the top in one screen area oa defined by the frame data 202. The individual area display AUs are arranged in the order of display area AU5, single item display area AU4, search key AU9, current area AU2, total amount area AU3, and function key shortcut AU8.

  In the above example, as an example, the smallest element (for example, avocado) and the category display area AU5 in the single item display area AU4 are generated using the two minimum areas ma. Therefore, as is apparent from referring to FIGS. 6A and 6B, it can be seen that all the other area display AUs are areas that are integral multiples of the minimum area ma.

  In such a configuration, the operator picks up the product AL stored in the first basket 133a and reads the product AL by pointing the attached barcode BC toward the reading window 103a of the barcode scanner 103. Position in region RA. At this time, light is emitted from the light source LED 113, the reflected light of the barcode BC is received by the CCD sensor 114, and is decoded into a product code by the decoding unit 155. In this way, the operator causes the code symbol reading device 101 to read the product code attached to the product AL as the barcode BC. Thereafter, the operator puts the product AL whose product code has been read into the second basket 133b. The product code read by the code symbol reader 101 is transmitted to the POS terminal 11. The CPU 51 of the POS terminal 11 executes a process of acquiring a corresponding unit price from a PLU file (not shown) based on the product code and calculating a settlement amount based on the unit price. Such a series of processing is merchandise sales data processing, and details thereof will be described with reference to FIG.

  FIG. 7 is a flowchart showing a flow of merchandise sales data processing in the POS terminal 11 and the code symbol reader 101. This processing is executed in the POS terminal 11 according to the computer program copied by the CPU 51 to the RAM 53, and in the code symbol reader 101, the CPU 161 executes it according to the computer program recorded as firmware in the ROM 162.

  The CPU 161 of the code symbol reader 101 determines the input of a product code (step S101). The product code is input by reading the barcode BC with the barcode scanner 103 as one method. As another method of inputting the product code, there is also a method of touch-designating the single item display displayed in the single item display area AU4 on the touch panel 105 in the registration screen RS of the product displayed on the display 106. When a product displayed as a single item in the single item display area AU4 is touch-designated on the touch panel 105, the CPU 161 of the code symbol reader 101 refers to the position specifying data 205 stored in the screen data 201 (FIG. 3). It is possible to recognize which single item display has been selected and designated (see step S6 in FIG. 5).

  The CPU 161 waits for the input of the product code (step S101). When the input of the product code is determined (Y in step S101), the product code output by the barcode scanner 103 or the touch designation is made by the touch panel 105. The product code of the product displayed individually in the single product display area AU4 is transmitted to the POS terminal 11 (step S102).

  The CPU 51 of the POS terminal 11 is on standby for receiving a product code from the code symbol reading device 101 (step S21). When it is determined to receive a product code (Y in step S21), the CPU 51 of the POS terminal 11 is based on the input product code. The corresponding product name and unit price data are called from the PLU file (not shown) and temporarily stored in the work area of the RAM 53 (step S22). Then, the display update of the operator display 15 and the customer display 17 is executed (step S23). Then, the CPU 51 of the POS terminal 11 transmits the product name and unit price data retrieved from the PLU file (not shown) to the code symbol reader 101 (step S24).

  The CPU 161 of the code symbol reader 101 transmits a product code to the POS terminal 11 (step S102), and then waits for reception of product name and unit price data from the POS terminal 11 (step S103). Therefore, when it is determined that the product name and unit price data have been received from the POS terminal 11 (Y in step S103), display updates on the display 106 that the operator browses and the customer display 108 that the shopper browses are executed (step S104). .

  The CPU 51 of the POS terminal 11 transmits the product name and unit price data retrieved from the PLU file (not shown) to the code symbol reader 101 (step S24), and then determines whether or not a tightening operation is performed by the keyboard 14 (step S25). ). As an example, the closing operation is performed by pressing the subtotal key, placing a deposit amount with the numeric keypad, and then pressing the deposit / current total key. The subtotal key, the numeric keypad, and the deposit / current total key are assigned to any key of the keyboard 14. The CPU 51 of the POS terminal 11 repeats the processing from step S22 to step S25 if there is an input of a product code without a closing operation (N in step S25) (Y in step S21). On the other hand, when the CPU 51 of the POS terminal 11 determines the closing operation (Y in step S25), transaction data such as the total sales amount calculated based on the data temporarily stored in the work area of the RAM 53 is temporarily registered in the RAM 53. The product is registered in the area (step S26), and the display update of the operator display 15 and the customer display 17 is executed (step S27). Then, the CPU 51 of the POS terminal 11 issues a receipt in which transaction information based on such transaction data is printed by the receipt journal printer 16, and performs journal recording by the receipt journal printer 16 (step S28). Further, a transaction end notification is transmitted to the code symbol reading apparatus 101 (step S29), and the process ends. The store clerk gives the issued receipt to the customer and ends one transaction.

  When receiving the transaction end notification from the POS terminal 11 (Y in Step S105), the CPU 161 of the code symbol reader 101 executes clear processing such as RAM clear and display clear (Step S106), and ends the processing.

  Here, in the POS terminal 11 and the code symbol reading device 101 that construct the checkout system 1 of the present embodiment, it is extremely easy to create and change the product registration screen RS (see FIG. 6). There is also a high degree of freedom in the layout of the product registration screen RS that can be created. This point will be described.

  FIG. 8 is a schematic diagram showing various variations of the product registration screen RS displayed on the display 106 of the code symbol reader 101. For convenience of explanation only, one display example group is shown in FIGS. 8A and 8B, and another display example group is shown in FIGS. 8C and 8D. .

  When producing the screen data 201 constituting the product registration screen RS, first, coordinates (x, y) defining one screen area oa are determined, and frame data 202 is generated (see FIG. 3). At this time, the minimum area ma is determined by concept or as actual data. One screen area oa has a size that is an integral multiple of the minimum area ma.

  Next, a plurality of types of area display AUs are created, and area data 203 is generated (see FIG. 3). At this time, the area display AU is obtained by unitizing the minimum area ma in an integral multiple.

  Next, an arrangement position of each area display AU constituted by the generated area data 203 is determined. As an example, the arrangement position in this case is determined by the coordinates (x, y) of one screen area oa defined by the frame data 202. As another example, if it is assumed that the minimum area ma is included as actual data in one screen area oa in the frame data 202 and an ID number is set for each minimum area ma, The position of each area display AU may be determined as the ID number of the minimum area ma defined for the area display AU. Data for determining the arrangement position of each area display AU as described above is display position designation data 204 (see FIG. 3).

  And the registration screen RS of goods is produced | generated by producing | generating the position specific data 205 (refer FIG. 3) mentioned above.

  In the example of the registration screen RS shown in FIG. 8A, the title area AU1, the current area AU2, and the total amount area AU3 are displayed in order from the top in one screen area oa defined by the frame data 202, and below that. The category display area AU5 is displayed on the left side, and the single item display area AU4 is displayed on the right side. As an example, the smallest single item display shown in the single item display area AU4 forms the minimum area ma. Referring to FIG. 8 (a), the largest single item display (tomato, cucumber, etc.) shown in the single item display area AU4 is the minimum area ma for four pieces, the medium single item display (green leek with organic mud, leek washing) Each element of the (Cut) and category display area AU5 is composed of two minimum areas ma. Thus, it can be seen that all area display AUs are generated as units in which the minimum area ma is combined in an integral multiple.

  In the registration screen RS shown in FIG. 8B, the current area AU2 and the total amount area AU3 are positioned at the lowest position with respect to the registration screen RS shown in FIG. The arrangement position of the display area AU4 is switched. Such a layout change can be easily performed by changing the display position designation data 204.

  In an example of the registration screen RS shown in FIG. 8C, a title area AU1, a current area AU2, and a total amount area AU3 are displayed in order from the top in one screen area oa defined by the frame data 202, and below that. , A category display area AU5 on the left side, a single item display area AU4 in the center, and a detail display area (simple) AU7 on the right side.

  In the registration screen RS shown in FIG. 8D, the current area AU2 and the total amount area AU3 are positioned at the lowest position with respect to the registration screen RS shown in FIG. 8C, and the arrangement position and details of the category display area AU5 The arrangement position of the display area (simple) AU7 is switched. Such a layout change can be easily performed by changing the display position designation data 204.

  As described above, according to the present embodiment, a plurality of types of areas constituted by area data 203 whose display position is determined by display position designation data 204 in one screen area oa defined by frame data 202. The display AU is unitized. Moreover, the unit is a unit in which the minimum area ma for determining one screen area oa defined by the frame data 202 is combined in an integral multiple. Therefore, after appropriately setting the number of combinations of the minimum areas ma forming the area display AU composed of each type of area data, the unit of the area display AU is appropriately combined and the position is designated by the display position designation data 204. The product registration screen RS can be configured relatively simply and with a high degree of freedom.
