Description

  The present invention relates to a POS system apparatus, and more particularly to a POS system apparatus that can refer to receipt print data and the like.

  In computer systems, failures caused by software are often difficult to isolate because the operating status of the software is invisible. In order to solve this problem, a technique for storing and saving a program operation processing history as data is widely known. In addition, since a POS (Point Of Sales) system apparatus is generally operated in a predetermined operation order, the cause of the failure can be identified from the operation history, and a technique for storing and saving the operation history as data is also available. Widely known. However, these historical data are recorded on the assumption that a manufacturer engineer with specialized knowledge investigates and analyzes, and it is generally difficult for the user himself to investigate and analyze.

  As a technique related to these history data, for example, a history information display device described in Japanese Patent Application Laid-Open No. 2008-40560 or a failure information collection system described in Japanese Patent Application Laid-Open No. 2005-56074 is known. All of these are techniques relating to a method of recording history information, and no technique has been proposed for realizing the investigation / analysis by the user himself / herself in order to simplify the investigation / analysis of history information.

  FIG. 10 is a flowchart showing an example of the flow of recording history data when an input operation is performed in the POS system apparatus according to the present invention. In this flowchart, a case where an input operation for sales of transaction number 00001 is performed will be described as an example. First, the sales operation of transaction number 00001 is started, and the first operation is executed by the input unit 11 (S1). As a result, a line of transaction number 00001 is created in operation history DB 141, 00001 is recorded in transaction number recording unit 1411, and operation 1 is recorded at the top of operation history recording unit 1412 (S2). Subsequently, a line of transaction number 00001 is created in the processing history DB 142, 00001 is recorded in the transaction number recording unit 1421, and processing 1 is recorded at the top of the processing history recording unit 1422 (S3). Next, when the second operation of transaction number 00001 is executed (S4), operation 2 is recorded in the second operation history recording unit of the operation history DB 141 (S5), and the second operation history recording unit of the processing history DB 142 is second. Process 2 is recorded in (S6).

  Thereafter, although the flowchart is omitted, every time an input operation is performed, operation 3 is recorded in the operation history recording unit of the operation history DB 141, operation 4 is recorded in the fourth, and operation 4 is recorded in the fourth. In the history recording section, processing 3 is recorded third, and processing 4 is recorded fourth. Thereafter, when the transaction end input operation is performed tenth (S7), the operation 10 is recorded in the tenth operation history recording unit of the operation history DB 141, and the transaction end is indicated in the eleventh operation history recording unit. An END mark is recorded (S8). Further, the process 10 is recorded in the 10th process history recording section of the process history DB 142, and the END mark indicating the end of the transaction is recorded in the 11th process history recording section (S9).

  Further, the contents of the transaction are printed on a receipt paper (not shown) from the printing unit 13 (S10). In addition, a line of transaction number 00001 is created in the electronic journal DB 143, 00001 is recorded in the transaction number recording unit 1431, and the content printed in S10 is recorded as data in the receipt print data recording unit 1432 (S11). By using the transaction number as described above, data can be recorded in the operation history DB 141, the processing history DB 142, and the electronic journal DB 143 in a form related to each transaction.

  FIG. 11 is a flowchart showing an example of a flow of processing for referring to history data when a failure occurs in the POS system apparatus according to the present invention. First, a command for starting the electronic journal search screen 2 is input through the input unit 11, and the electronic journal search screen 2 is displayed on the display unit 12 (S21). The transaction number of the first transaction of the day is input from the input unit 11 and the receipt display button 22 is pressed (S22). The control unit 15 searches the electronic journal DB for the transaction number 1431 based on the input transaction number, and displays the receipt print data 1432 of the corresponding transaction number on the receipt print display unit 23 of the electronic journal search screen 2 (S23). The operator confirms the printed contents of the displayed receipt and determines whether or not the transaction has failed (S24, S25). An example of a transaction with a failure is, for example, a case where “210” is displayed where the price of the product B should originally be displayed as “315” in the receipt print content displayed in the receipt print display portion 23 of FIG. It is. In such a case, it is possible to easily determine whether or not the transaction is pertinent by referring to the receipt print content. If it is determined that the transaction is not a failure, the process returns to S22, and the processes after S22 are similarly performed with the second transaction number. If it is determined that the transaction is a faulty transaction, the process proceeds to an investigation of the history data of the transaction, and the operator determines which of the operation history and the processing history is to be investigated (S26).

  When investigating the operation history, the operation history display button 24 in the electronic journal search screen 2 is pressed (S27). Thereby, the operation history display screen 3 is displayed on the display unit 12 (S28). At this time, the transaction number 1411 of the operation history DB 141 is searched with the transaction number input on the electronic journal search screen 2 in S22, and the operation history 1412 of the corresponding transaction is displayed on the operation history display unit 32 of the operation history display screen 3 ( S29). The operator analyzes the operation history display, determines the operation actually performed in this transaction, and investigates the cause of the failure (S30).

  Since there is no need to find the corresponding transaction location in the operation history, the user can easily analyze it. Although not described in this flowchart, when the operation history print button 25 is pressed, the corresponding transaction is retrieved from the operation history DB 141 in the same manner as when the operation history display button is pressed, and the operation history is transferred from the printing unit 13 to the receipt sheet. Since it is printed, it is also possible to analyze the operation history with reference to the operation history print output 4.

  When investigating the processing history, the processing history display button 26 in the electronic journal search screen is pressed (S31). Thereby, the processing history display screen 5 is displayed on the display unit 12 (S32). At this time, the transaction number 1421 of the processing history DB 142 is searched with the transaction number input on the electronic journal search screen 2 in S22, and the processing history 1422 of the corresponding transaction is displayed on the processing history display section 52 of the processing history display screen 5 ( S33). The operator analyzes the processing history display, determines the processing actually operated in this transaction, and investigates the cause of the failure (S34).

  Although not described in this flowchart, when the processing history print button 27 is pressed, the corresponding transaction is searched from the processing history DB 142 and the processing history is transferred from the printing unit 13 to the receipt paper in the same manner as when the processing history display button is pressed. Since it is printed, it is possible to analyze the processing history with reference to the processing history print output 6.

  As a result of the analysis of the history data by the user himself / herself, if the cause of the failure can be identified, the user himself / herself deals with the failure (S35, S37). If the cause of the failure cannot be identified, the manufacturer is requested to investigate (S35, S36). In other words, it is not necessary to ask the manufacturer for a trouble that can be dealt with by the user, and it is possible to expect a reduction in the trouble solution time and a reduction in the investigation cost.

  As described above, the data reference method of the POS system apparatus according to the present invention creates a transaction number row in the operation history database corresponding to the transaction, and records the contents of the input operation as data in the transaction number row. A transaction number line is created in the process history database corresponding to the first step and the transaction, and the transaction contents performed in the apparatus corresponding to the contents of the input operation are used as data in the transaction number line. A second step of recording, a third step of recording the contents of the next input operation as data in the transaction number row of the operation history database, and the next step in the transaction number row of the processing history database. A fourth step of recording processing contents performed in the apparatus in response to the contents of the input operation as data, a fifth step of repeating the third and fourth steps, and after the fifth step Creating a row of the transaction number in the child journal database, and recording receipt print data created based on the result of processing a series of data input in the transaction in the row of the transaction number A process, a seventh process of repeatedly performing the first to sixth processes, receipt print data recorded in the electronic journal database, data of contents of input operations recorded in the operation history database, and And an eighth step of making it possible to refer to at least one piece of processing content data recorded in the processing history database for each transaction number.

  These steps can be performed by causing a computer to execute the following program. That is, this program creates a transaction number line in the operation history database corresponding to the transaction on the computer, and records the contents of the input operation as data in the transaction number row, corresponding to the transaction. The transaction history line is created in the transaction history database, and the transaction history is recorded in the transaction number row as the data corresponding to the contents of the input operation. A third procedure for recording the contents of the next input operation as data in the transaction number row of the database, and a row in the apparatus corresponding to the contents of the next input operation in the transaction number row of the processing history database A fourth procedure for recording the processing content to be recorded as data, a fifth procedure for repeating the third and fourth procedures, and an electronic journal database after the fifth procedure. 6th procedure which records the receipt print data created based on the result of processing a series of data inputted in the transaction concerned in the line of the transaction number To seventh procedure for repeating the sixth procedure, receipt print data recorded in the electronic journal database, data of contents of input operation recorded in the operation history database, and recorded in the processing history database An eighth procedure for enabling reference to at least one piece of processing content data for each transaction number is executed. This program can be stored in the control unit or storage unit of the POS system apparatus, but is not limited to this, and can also be stored in a recording medium such as a CDROM or provided from outside by a communication means.

  The POS system device prints a sales receipt for each transaction, but the printed content is recorded as data in the electronic journal DB and has a function that can be referred to later. When the sales details of a transaction in which a failure has occurred are known, it is possible to identify the transaction by referring to the receipt print data in the electronic journal DB. In the present invention, as described above, the history data can be extracted in association with the transaction number by recording the operation history and the processing history of the POS system device in the database for each transaction number given in transaction units. For this reason, after identifying the trouble transaction in the receipt print data of the electronic journal DB, the history data of the transaction can be taken out and referred to, and the analysis of the trouble or the like can be facilitated.
