  Hereinafter, a merchandise sales data processing apparatus according to an embodiment will be described with reference to the drawings. In this embodiment, the merchandise sales data processing apparatus is applied to a POS (Point Of Sales) system.

  FIG. 1 is a block diagram showing an outline of the POS system 1. The POS system 1 includes one POS server 10 and a plurality of POS terminals 20. Both the POS server 10 and each POS terminal 20 are equipped with computers. The POS server 10 and each POS terminal 20 are connected via a network 30 such as a LAN (Random Access Memory) so as to be capable of bidirectional communication.

  The POS server 10 has a product master file 11. The product master file 11 stores various information related to the product in association with the product code unique to the product for identifying each product.

  FIG. 2 is a schematic diagram showing a data record 11 </ b> R of one product stored in the product master file 11. As shown in FIG. 2, the product master file 11 stores a message number MNo and a pattern number PNo together with the product name, unit price, etc. of the product identified by the product code in association with the product code.

  The message number MNo is a record identification number of the message table 12. As shown in FIG. 3, the message table 12 records message data notified to the operator and title data attached to the message in association with a series of message numbers.

  The pattern number PNo is a record identification number of the pattern table 13. As shown in FIG. 4, the pattern table 13 records display format data and an erase program ID in association with a series of pattern numbers. The display format data is format data of a pop-up window used for displaying the message. The erase program ID is an ID assigned to a program for erasing the pop-up window.

  Here, in the present embodiment, for convenience of explanation, the format data of the pop-up window is assumed to be three types of pop-up windows PW1, PW2, and PW3 shown in FIGS. 5A, 5B, and 5C, respectively. That is, the pop-up window PW1, which is the first format pattern, displays the message and its title in the window frame, and displays the button images of the confirm button B1 and the cancel button B2. The pop-up window PW2, which is the second format pattern, displays the message and its title in the window frame, and also displays the button image of the confirmation button B1. The pop-up window PW3, which is the third format pattern, similarly displays a message and its title in the window frame, and displays a button image of the close button B3.

  The confirmation button B1 and the close button B3 function as confirmation input buttons for instructing continuation of information processing. The cancel button B2 functions as a confirmation input button that instructs to stop information processing. The confirmation button B1 and the cancel button B2 are forced to be input. The close button B3 is not forced to be input.

  Therefore, as shown in FIG. 4, for the pop-up window PW1, when the confirmation button B1 is input, the pop-up window PW1 is deleted and the information processing is continued, and when the cancel button B2 is input, the pop-up window PW1 Is set to the ID [pid01] of the erasure program for erasing and canceling information processing. For the pop-up window PW2, an ID [pid02] of an erasure program for erasing the pop-up window PW2 and continuing information processing after inputting the confirmation button B1 is set. The pop-up window PW3 is set with an ID [pid03] of an erasure program that erases the pop-up window PW3 and continues information processing when there is an arbitrary input.

  The POS server 10 stores the product master file 11, the message table 12, and the pattern table 13 in a storage device such as an HDD (Hard Disk Drive). The POS server 10 has a maintenance mode for the product master file 11, the message table 12, and the pattern table 13, and the operator accesses the POS server 10 using a maintenance personal computer (not shown), thereby Data of the product master file 11, the message table 12, and the pattern table 13 can be added, changed, or deleted as appropriate.

  FIG. 6 is a block diagram showing a main configuration of the POS terminal 20. The POS terminal 20 includes a CPU (Central Processing Unit) 201 that plays the central role of the computer. The CPU 201 is connected to a ROM (Read Only Memory) 203, a RAM (Random Access Memory) 204, an HDD (Hard Disk Drive) 205, a clock unit 206, a communication interface via a bus line 202 such as an address bus and a data bus. A keyboard controller 208, a touch panel controller 209, a display controller 210, a printer controller 211, a scanner interface 212, and the like are connected.

  The ROM 203 and the RAM 204 constitute a main storage unit in which data is read and written by the CPU 201. The HDD 205 constitutes an auxiliary storage unit for storing large-capacity data such as programs. The clock unit 206 measures the current date and time. The communication interface 207 transmits data to the POS server 10 via the network 30 and receives data transmitted from the POS server 10 via the network 30.

Control the data communication that takes place.

  The keyboard controller 208 controls the keyboard 221. The keyboard 221 is provided with various function keys such as a subtotal key, a deposit / current total key, a confirmation key, a cancel key, and a clear key in addition to numeric keys for entering numerical values.

  The touch panel controller 209 controls the touch panel 222 including a flat display and a touch panel sensor. The touch panel 222 functions as an operator display. The touch panel controller 209 controls screen display on the flat display. The touch panel controller 209 acquires coordinate data indicating the touch position when the screen of the flat display is touched by the operator.

  The display controller 210 controls the screen display of the customer display 223. The printer controller 211 controls the driving of the printer 224 for printing receipts. The scanner interface 212 receives the barcode data read by the scanner 225. Each product has a barcode indicating a product code unique to the product.

  When the product code is input from the keyboard 221 or the scanner 225 which is an input device, the CPU 201 starts the product sales data processing according to the procedure shown in the flowchart of FIG. This process is realized by a program stored in the ROM 203 or the HDD 205.

  First, the CPU 201 makes an inquiry to the POS server 10 with the input product code, and product information (product name, unit price, message number MNo, pattern number PNo) set in the product master file 11 corresponding to this product code. Etc.) (ST1). Then, the CPU 201 creates a registration screen including the product name, unit price, etc. of the detected product information, and displays it on the touch panel 222 and the customer display 223 (ST2: first screen display means).

  FIG. 11 shows an example of the registration screen 40 displayed on the touch panel 222. The registration screen 40 includes a current area 41, a detail area 42, and a total area 43. The current area 41 displays the product name, unit price, number of sales, and sales price of the product registered this time. The detail area 42 displays a list of product names, unit prices, sales points, and sales amounts of already registered products. The total area 43 displays the total amount of one transaction including the product registered this time.

  After displaying the registration screen 40, the CPU 201 determines whether or not the message number MNo of the detected product information is “0” (ST3). When the message number MNo is “0” (NO in ST3), the message display setting is not made for the product registered this time. In this case, the CPU 201 executes product registration processing. That is, the CPU 201 registers product sales data such as the product code, product name, unit price, number of sales, sales price, etc. of the product registered this time in the sales memory of the RAM 204 (ST13). As described above, the CPU 201 ends the current merchandise sales data processing.

  On the other hand, when the message number MNo is not “0” (YES in ST3), the message display setting is made for the product registered this time. In this case, the CPU 201 makes an inquiry to the POS server 10 with this message number MNo, and detects title data and message data set in the message table 12 corresponding to this message number MNo (ST4). Furthermore, CPU201 acquires pattern number PNo from the detected merchandise information (ST5). Then, the CPU 201 makes an inquiry to the POS server 10 with this pattern number PNo, and detects the display format data and the erase program ID set in the pattern table 13 corresponding to this pattern number PNo (ST6).

  Thereafter, the CPU 201 sets the title data in the title area of the display format data, sets the message data in the message area, and edits the pop-up window (ST7: second screen creation means). Then, the CPU 201 displays the pop-up window so as to overlap the registration screen 40 of the touch panel 222 (ST8: second screen display means).

  FIG. 12 shows an example of a pop-up window 51 displayed on the registration screen 40. This pop-up window 51 is an example in which the title data “Sales confirmation” and message data “Sales target product has been registered. Please check” are set in the pop-up window PW1 which is the first format pattern. is there.

  Incidentally, when similar text data and message data are set in the pop-up window PW2 which is the second format pattern, a pop-up window 52 shown in FIG. 13A is displayed. When similar text data and message data are set in the pop-up window PW3 that is the third format pattern, a pop-up window 53 shown in FIG. 13B is displayed.

  After displaying the pop-up windows 51 to 53 in step ST8, the CPU 201 determines the erase program ID detected together with the display format data (ST9). Here, when the erase program ID is “pid01”, that is, when the pop-up window 51 is displayed, the CPU 201 jumps to the first erase process by the erase program having the program ID “pid01” (ST10). ). The procedure of this process is specifically shown in FIG.

  First, the CPU 201 determines whether or not a confirmation input has been made (ST21). When the confirmation input is not made (NO in ST21), the CPU 201 determines whether or not the cancellation input is made (ST22). If no cancel input has been made (ST22). The CPU 21 determines whether or not a confirmation input has been made again (ST21). In this way, the CPU 201 forces input of confirmation or cancellation.

  When the confirmation button B1 of the pop-up window 51 is touched or the confirmation key of the keyboard 221 is input (YES in ST21), the confirmation input has been made, so the CPU 201 deletes the pop-up window 51 (ST22: screen deletion) means). Thereafter, the CPU 201 executes the product registration process in step ST13, and ends the current product sales data process.

  On the other hand, when the cancel button B2 of the pop-up window 51 is touched or the cancel key of the keyboard 221 is input (YES in ST22), the cancel input is made, so the CPU 201 deletes the pop-up window 51. (ST24: Screen erasing means). Thereafter, the CPU 201 ends the current product sales data process without executing the product registration process.

  On the other hand, when the erase program ID is “pid02”, that is, when the pop-up window 52 is displayed, the CPU 201 jumps to the second erase process by the erase program having the program ID “pid02” (ST11). . The procedure of this process is specifically shown in FIG.

  First, the CPU 201 determines whether or not a confirmation input has been made (ST31). When confirmation input is not made (NO in ST23), the CPU 21 waits for confirmation input (ST31). That is, the CPU 201 forces confirmation input. When the confirmation button B1 of the pop-up window 51 is touched or the confirmation key of the keyboard 221 is input (YES in ST31), the confirmation input is made, so the CPU 201 deletes the pop-up window 51 (ST32: Screen erasing means). Thereafter, the CPU 201 executes the product registration process in step ST13, and ends the current product sales data process.

  If the erase program ID is “pid03”, that is, if the pop-up window 53 is displayed, the CPU 201 jumps to the third erase process by the erase program having the program ID “pid03” (ST12). . The procedure of this process is specifically shown in FIG.

  First, the CPU 201 determines whether or not the close button B3 has been input (ST41). If not input (NO in ST41), the CPU 21 determines whether or not there is a key input from the keyboard 221 (ST42). When there is no key input (NO in ST42), the CPU 201 determines whether or not the close button B3 is input again (ST41). Thus, the CPU 201 waits for the close button B3 to be input or for any key input. When the close button B3 is input (YES in ST41) or any key is input (YES in ST42), the CPU 201 deletes the pop-up window 51 (ST42: screen deleting means). Thereafter, the CPU 201 executes the product registration process of step ST13 and ends the current information processing.

  It should be noted that the erase programs having program IDs “pid01”, “pid02”, and “pid03” are stored in the ROM 203 or the HDD 205.

  As described above, in the POS system 1 of the present embodiment, when the message number MNo and the pattern number PNo are set for the product registered for sale at the POS terminal 20, a pop-up window is displayed. That is, in the course of the merchandise sales data processing, if there is data input of a merchandise for which the message number MNo and the pattern number PNo are set, a pop-up window is displayed over the registration screen 40 related to the merchandise sales data processing. The The pop-up window is obtained by setting title data and message data corresponding to the message number MNo to display format data corresponding to the pattern number PNo.

  That is, when a product having “P01” set as the pattern number PNo is registered, a pop-up window PW1 having the format shown in FIG. 5A is displayed. Therefore, in this case, the operator of the POS terminal 20 performs a confirming operation or a canceling operation and closes the pop-up window PW1. On the other hand, when a product having “P02” set as the pattern number PNo is registered, a pop-up window PW2 having a format shown in FIG. 5B is displayed. Therefore, in this case, the operator of the POS terminal 20 performs a confirmation operation and closes the pop-up window PW2. When a product having “P03” set as the pattern number PNo is registered, a pop-up window PW3 having a format shown in FIG. 5C is displayed. Therefore, in this case, the operator of the POS terminal 20 performs the operation of the close button B3 or some key operation to close the pop-up window PW3.

  Thus, according to the POS system of the present embodiment, the pattern of the pop-up window displayed for the product is determined depending on the pattern number PNo set for each product. The pattern number PNo for each product is set in the product master file 11, and the number can be arbitrarily changed by the maintenance work of the POS server 10. Therefore, the pattern of the pop-up window to be displayed when registering each product, that is, the input condition for deleting the pop-up window can be easily changed.

Hereinafter, other embodiments will be described.
In the above embodiment, the message table 12 and the pattern table 13 are stored in the POS server 10, and an inquiry is made from the POS terminal 20 to the POS server 10 in the processes of steps ST4 and ST6 in FIG. In this regard, the message table 12 and the pattern table 13 may be stored in the HDD 205 of the POS terminal 20 so that the inquiry process is unnecessary. Further, the POS terminal 20 includes a data file that sets and stores a message number and a pattern number corresponding to at least the product code of each product, thereby realizing a function as a product sales data processing device alone. It is also possible.

  Further, the pop-up window pattern is not limited to the three types (pop-up window PW1, pop-up window PW2, pop-up window PW3) of the above-described embodiment. The present embodiment can cope with pop-up windows of various patterns depending on the setting of the pattern table 13.

  In addition, the POS system of the present embodiment can be realized using cloud computing. More specifically, a software provision form called software as a service (SaaS) is suitable.

The POS system 60 includes a cloud 61 and a plurality of communication networks 62 for each POS terminal 20. The cloud 61 further includes a POS server 10.

  Each POS terminal 20 can communicate with the cloud 61 via the corresponding communication network 62. As the communication network 62, the Internet, a private network, a next generation network (NGN), a mobile network, or the like can be used as appropriate.

  In the POS system 60 having such a configuration, in the process of step ST1 among the processes shown in FIG. 7, the process of detecting the product information specified by the product code queried from the product master file 11 is performed on the cloud 61 side. Although it is executed by the POS server 10, the subsequent processes of steps ST <b> 2 to ST <b> 13 may be executed by either the POS server 10 or the POS terminal 20.

  Further, when a plurality of processes in steps ST1 to ST13 are executed by the POS server 10, these processes may be executed by a single server or may be distributed by a plurality of servers.

  By the way, when at least one of the steps ST2 to ST13 is executed by the POS terminal 20, a program storage unit (which the POS terminal 20 has in advance) stores a program for causing the computer of the POS terminal 20 to execute the process. ROM 203 or HDD 205) may be stored, or the above-described program may be stored in a storage unit included in the cloud 61, and may be provided from the cloud 61 to the POS terminal 20 as necessary. When the above program is given from the cloud 61 to the POS terminal 20, the POS server 10 has a function of transmitting the above program to the POS terminal 20.

  Further, a similar program recorded on the recording medium may be installed in the POS terminal 20. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by the apparatus. Further, the function obtained by installing or downloading the program may be realized in cooperation with an OS (operating system) in the apparatus.

  Moreover, although the said embodiment demonstrated the POS system 1 and 60, this invention is applicable also to the other information processing apparatus or information processing system which uses a pop-up window.
