Description

The present invention relates to a sales data processing apparatus and program for transmitting / receiving file data to / from a server apparatus using an FTP (File Transfer Protocol) protocol.

Conventionally, a sales management system has been proposed in which sales data of a data processing device such as an ECR (electronic cash register) or a POS terminal is collected in a server in a data center or the like, and the collected sales data is aggregated. For example, Patent Document 1 describes a sales management support apparatus that collects and stores sales data from a plurality of POS terminals via a LAN, and transmits the collected sales data to an FTP server that performs aggregation processing.
Japanese Patent Laid-Open No. 2003-67847

Conventionally, data transmission / reception between the ECR and the server is performed using a dedicated tool or protocol. However, when the function is expanded or maintenance is performed, both the ECR and the server are changed. There was a problem in scalability and ease of maintenance.
On the other hand, if data transmission / reception between the ECR and the server is performed using a general-purpose protocol such as FTP, the general-purpose protocol simply transmits / receives the file data of each other as it is, so the data format on the receiving side matches. There was a problem that no data was written. Further, the ECR includes a file in which setting data and operation data such as sales data are mixed like a department file 231 shown in FIG. 5, but general-purpose protocols such as FTP can only transmit and receive in file units. Since it is possible, for example, the server side receives only the calculation data of the department file from the ECR, or the server side transmits only the department file setting data to the ECR and rewrites only the setting data in the department file. There was a problem that could not be made.

An object of the present invention is to enable reading of sales data and setting data of a sales data processing apparatus from a server apparatus using a general-purpose protocol .

For example, FIG. 7 is a response file 236 for storing the job start result of the aggregation processing shown in FIG. 12, and an ECRid for identifying each ECR that has ended abnormally and an error code indicating the type of error that occurred in that ECR (For example, “00” or the like if data transmission cannot be performed during the registration operation) is stored in association with each other. In this embodiment, only when the job ends abnormally is stored as the job start result. However, a normal code indicating that the job ended normally is provided, and both normal and abnormal results are returned as responses. The file 236 may be stored.

  Further, the RAM 23 has an FTP mode storage memory for storing the type of the FPT mode (X mode, Z mode, AUTOTOPM mode, JOB mode, no mode designation) designated by CD processing (see FIG. 14) described later. Yes. The FTP mode is an operation mode that is applied when processing (such as GET processing (see FIG. 13) described later) for a command received from the PC 1 based on the FTP protocol.

  The RAM 23 stores a DIR (directory) table. As shown in FIG. 8, the DIR table indicates whether or not the contents of each file stored in the file storage memory of the RAM 23 are contents that can be accessed (read and / or written) from the PC 1 in each FTP mode. This is a list of tables. As shown in the DIR table, a file accessible from the PC 1 in each FTP mode is determined in advance according to the file contents of each file. In the AUTOPGM mode, a file whose setting data is included in the file content can be accessed. In the X mode, it is possible to access a file whose operation data is included in the file content. In the Z mode, it is possible to access a file including operation data that can be cleared to zero. In the JOB mode (described later in detail), only the response file 236 can be accessed.

  The contents of the DIR table are rewritten by the CPU 21 according to the time zone. For example, when unit price data cannot be changed in the morning, in the morning, the DIR table is rewritten to indicate that access to the department file 231 and the PLU file 232 is impossible in the AUTOPGM mode, indicating that access is impossible. . In addition, when the settlement from the PC 1 is not accepted during business hours, it is rewritten that access to each file in the Z mode is impossible until the predetermined time zone is reached, and it is displayed that access is impossible.

  Further, the RAM 23 stores a transfer waiting memory that temporarily stores conversion data waiting to be transferred in a GET process, which will be described later, and a person-in-charge code of the current operator in accordance with the operation of the clerk key of the input device 22. It has a person-in-charge memory.

  The drawer 28 is a drawer that stores cash.

  Since the functional configuration of the slave ECR 2b is the same as that of the master ECR 2a described above, the same components are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, since the slave ECR 2b does not perform file transfer with the PC 1, it is not necessary to store the FTP client program and FTP conversion processing program in the recording device 27, and the slave ECR 2b communicates with the transmission control unit 24. An interface for connecting to the network N1 may not be provided.

Next, the operation of this embodiment will be described.
FIG. 9 is a flowchart showing main processing executed by the CPU 21 of the master ECR 2a. This processing is realized by software processing in cooperation with the CPU 21 and the main processing program stored in the recording device 27 when the master ECR 2a is turned on.

  When the registration mode is designated by the mode key of the input device 22 and input is performed in the registration mode (step S1), the registration process shown in FIG. 10 is executed (step S2).

  FIG. 10 is a flowchart showing a registration process executed by the CPU 21 of the master ECR 2a. This process is a process realized by software processing in cooperation with the CPU 21 of the master ECR 2a and the registration processing program stored in the recording device 27.

  First, when an input is performed by the input device 22, it is determined whether or not the input is a product registration instruction. If it is determined that the input is a product registration instruction (step T <b> 1; YES), the product registration is performed. It is determined whether or not it is the first product registration of one transaction, and if it is determined that it is the first product registration of one transaction (step T2; YES), one transaction total memory of the RAM 23 is cleared (step S2). T3). Next, various sales data files such as the fixed total file 230, the department file 231 and the PLU file 232 are updated (step T4), and the product data such as the product name (product code) and the price is received by the printing device 26 in the receipt and journal. Are displayed on the display device 25 (step T5), the amount of the product is added to one transaction total memory of the RAM 23 (step T6), and the process returns to step T1.

  On the other hand, if it is determined in step T1 that the input from the input device 22 is not a product registration instruction (step T1; NO), it is determined whether or not the input is a tightening process instruction. Is determined (step T7; YES), a tightening process is executed (step T8). That is, the total transaction amount stored in the total transaction memory is read and displayed on the display device 25. Also, the amount of change is calculated based on the amount received. When the fastening process is completed, a receipt is issued by the printing device 26 (step T9), and the process returns to step S1 in FIG.

  In step S1 of FIG. 9, when input in the registration mode is not performed by the input device 22 (step S1; NO) and input is performed in another operation mode (step S3; YES), another input is performed based on the input. Processing in the operation mode is executed (step S4).

  On the other hand, if there is no input in the registration mode and no input in the other mode and it is in the non-processing state (step S3; NO), whether or not a command is received from the PC 1 based on the FTP protocol via the transmission control unit 24. Is not received (step S5; NO), the process returns to step S1. When it is determined that a command from the PC 1 has been received (step S5; YES), the received command is determined, and when it is determined that the received command is a PUT command (step S6; YES), FIG. Is executed (step S7), and the process returns to step S1.

  If it is determined that the received command is not a PUT command (step S6; NO) and is a GET command (step S8; YES), the GET process shown in FIG. 13 is executed (step S9), and the process proceeds to step S1. Return to.

  If it is determined that the received command is not a GET command (step S8; NO) and is a CD command (step S10; YES), the CD process shown in FIG. 14 is executed (step S11), and the process is step S1. Return to.

  If it is determined that the received command is not a CD command (step S10; NO) and is a DIR command (step S12; YES), the DIR process shown in FIG. 15 is executed (step S13), and the process proceeds to step S1. Return to.

  If it is determined that the received command is not a DIR command (step S12; YES), processing according to the received other command is executed (step S14), and the processing returns to step S1.

Hereinafter, each of PUT processing, GET processing, CD processing, and DIR processing executed in response to a command based on the FTP protocol from the PC 1 will be described.
[PUT processing]
First, the PUT process will be described.
FIG. 11 is a flowchart showing a PUT process executed by the CPU 21 of the master ECR 2a. This process is a process realized by software processing in cooperation with the CPU 21 of the master ECR 2a and the PUT processing program stored in the recording device 27.

  First, the content of the file data received together with the PUT command from the PC 1 is analyzed (step P1), and if the result of the analysis determines that the content of the received file data is a JOB activation command (step P2; YES) The type of command in the received file is discriminated (step P3), processing (JOB) corresponding to the discriminated command type is started (step P4), and the processing returns to step S1 in FIG.

  For example, if a file called “PUT JOBSEND.TXT” is received from PC 1 and analyzed, the result is a job start command indicating the totaling process of the fixed total file 230 “J 21 X 11 REPORT”. Aggregation processing of the total file 230 is started. In this way, by sending the file data describing the job start command by the FTP protocol from the PC 1 side to the ECR 2a, it becomes possible to start the job from the PC 1 to the ECR 2a.

FIG. 12 is a flowchart showing a counting process as an example of a process activated by a JOB activation command.
First, it is determined whether or not it is the aggregation timing (step T11). If it is the aggregation timing (step T11; YES), the sales data of the file designated by the command is collected from each slave ECR 2b and added up cumulatively. (Step T12). More specifically, the sales data collection command of the file specified by the JOB start command (for example, in the case of “J 21 X 11 REPORT” described above, the fixed total file 230) is transmitted to each slave ECR 2b. Is done. In each slave ECR 2b, when the sales data collection command is received, the sales data is read from the designated file and transmitted to the master ECR 2a, and the read sales data is erased from the designated file (zero clear). ) When the sales data of the designated file is received from each slave ECR 2b, the received sales data and the sales data of the designated file of the master ECR 2a are cumulatively added to the corresponding fields of the summary file 234.

  When the aggregation of sales data ends normally (step T13; YES), this process ends. If any of the slave ECRs 2b is powered off, is being registered, or a communication error occurs, sales data cannot be received and sales data aggregation ends abnormally (step T13; NO). The identification code (id) of the slave ECR 2b that has ended abnormally and the error code corresponding to the abnormal state are stored in the response file 236 of the RAM 23 (step T14), and this process ends.

  On the other hand, when it is not the aggregation timing (for example, during business hours) (step T11; NO), an error code indicating that it is not the aggregation timing is stored in the response file 236 (step T15). Ends.

  JOBs that can be started from the PC 1 include, for example, a Z lock process for not accepting operator registration, a Z lock release process for releasing Z lock, a batch maintenance process, and an automatic power Auto power ON / OFF processing for turning ON / OFF the power can be performed.

  Returning to FIG. 11, when it is determined that the received file content is not a JOB start command as a result of the analysis in step P1 (step P2; NO), the received file data from the file name of the received file data. Is determined (step P5), the field to which the received data is written is determined from the data content in the received file (step P6), and the data in the received file is predetermined. The data is converted into ECR format data (step P7) and temporarily stored in the work area of the RAM 23 (step P8). For example, when a file having the file name “FILE005.txt” of the department file is received from the PC 1, the department file “FILE005.DAT” in which the file name of the write destination is stored in the RAM 23 based on the file name. It is determined that conversion from text data to binary data is necessary. In addition, the field in which each data is written is determined based on the contents of each data in the received file, specifically the length of each data, the type of data (character or numeric data, etc.).

  After the conversion, the conversion data temporarily stored in the RAM 23 is written in the write destination field of the write destination file determined in Steps P5 and P6 (Step P9), and the conversion data temporarily stored in the RAM 23 is transmitted to the transmission control unit 24. Through the second I / F, the write destination file and field are transmitted to each slave ECR 2b in an identifiable manner (step P10), and the process returns to step S1 in FIG.

  As described above, the ECR is transmitted from the PC 1 side to the master ECR 2a using the PUT command based on the FTP protocol to write data (for example, setting data) to be written in the files stored in the master ECR 2a and the slave ECR 2b. Since the data is converted into ECR format data on the side, and the area to be written, that is, the file name and field to be written, is determined and written, the setting data can be easily transferred from the PC 1 to the master ECR 2a and the slave ECR 2b using a general protocol such as FTP Writing can be performed.

[GET processing]
Next, the GET process will be described.
FIG. 13 is a flowchart showing the GET process executed by the CPU 21 of the master ECR 2a. This process is a process realized by software processing in cooperation with the CPU 21 of the master ECR 2a and the GET processing program stored in the recording device 27.

  Here, the GET command is a command that is transmitted when it is desired to acquire file data stored in the master ECR 2a from the PC 1 side. On the master ECR 2a side, if the FTP mode is designated by the CD command from the PC 1 in advance. The data corresponding to the FTP mode can be transmitted among the files requested from the PC 1.

  First, the content of the data indicating the file name received from the PC 1 together with the GET command is determined (step G1), and the FTP mode stored in the FTP mode storage memory is determined (step G2). In the FTP mode storage memory, data indicating the FTP mode designated by the CD command transmitted from the PC 1 is stored (see FIG. 14). When the FTP mode determined in step G2 is the X mode or the Z mode (step G3; YES), calculation is performed on the file having the file name determined in step G1 among the files stored in the file storage memory of the RAM 23. It is determined whether or not data is stored. If calculation data is stored (step G4; YES), the calculation data is read from the determined file and temporarily stored in the work area (step G5). The process proceeds to step G14.

  In step G4, when it is determined that the operation data is not stored in the file having the file name determined in step G1 (step G4; NO), a file indicating a mode error is created and temporarily stored in the work area. (Step G6), the process proceeds to Step G14.

  If the FTP mode determined in step G2 is neither the X mode nor the Z mode (step G3; NO), it is determined whether the FTP mode is the AUTOPGM mode, and if the FTP mode is the AUTOPGM mode (step G7; YES). It is determined whether or not the setting data is stored in the file having the file name determined in step G1, and when the setting data is stored (step G8; YES), the setting data is read from the determined file. Is temporarily stored in the work area (step G9), and the process proceeds to step G14.

  On the other hand, if it is determined in step G8 that the setting data is not stored in the file having the file name determined in step G1 (step G8; NO), a file indicating a mode error is created in the work area. Temporarily stored (step S10), the process proceeds to step G14.

  On the other hand, when the FTP mode determined in step G2 is not the AUTOTOPM mode (step G7; NO) and the JOB mode (step G11; YES), the response file 361 is read (step G12), and the process proceeds to step G14. Transition.

  On the other hand, if the FTP mode determined in step G2 is not the JOB mode (step G11; NO), that is, if no mode is specified, all data is read from the file having the file name determined in step G1. The data is temporarily stored in the work area, and the process proceeds to step G14.

  In step G14, the data read to the work area is converted into a file format designated by the PC 1 and stored in the transfer area of the RAM 23 (step G15). The file format designated from the PC 1 is determined by the data identifier indicating the file name received together with the GET command. For example, when “GET FILE05.TXT” is received, the read data is converted into a text format file. Then, the file data stored in the transfer area is transmitted to the PC via the first I / F of the transmission control unit 24 (step G16). If the FTP mode is the Z mode (step G17; YES), the calculation data is further cleared to zero (erased) from the original file in which the calculation data read in step G5 is stored. Performed (step G18), the process returns to step S1 in FIG.

  As described above, in the GET process, it is possible for the operator to receive the data to be acquired in the desired file format by specifying the name and format of the file to be acquired from the PC 1 side. Further, if the FTP mode is designated in advance, it becomes possible for the user to select and receive necessary data (for example, only calculation data such as sales data). For example, when “GET FILE05.TXT” is specified, if the FTP mode is set to the X or Z mode in advance, only the calculation data of the department file 231 shown in FIG. If the FTP mode is set to the AUTOPGM mode in advance, only the setting data of the department file 231 shown in FIG. 5, that is, the character and unit price can be acquired on the PC 1 side. Further, if the FTP mode is set to the Z mode and, for example, sales data in a department total file is designated, the sales data can be settled from the PC 1 side and collected on the PC 1 side.

[CD processing]
Next, CD processing will be described.
FIG. 14 is a flowchart showing a CD process executed by the CPU 21 of the master ECR 2a. This process is a process realized by software processing in cooperation with the CPU 21 of the master ECR 2a and the CD processing program stored in the recording device 27.

  When the CD command and data indicating the type of FTP mode are received from the PC 1, the name of the received operation mode is stored in the FTP mode storage memory of the RAM 23 (step C1), and the process returns to step S1 in FIG.

The FTP mode stored in the FTP storage memory of the RAM 23 is referred to when processing for another command received from the PC 1, and processing corresponding to this FTP mode is executed.
For example, when a CD command “CD AUTOPGM” and data indicating the FTP mode are received from the PC 1, data indicating “AUTOPGM” is stored in the FTP mode storage memory. As a result, in the above-described GET process, it is possible to perform a process according to the setting mode in which only the setting data of the file having the designated file name is read and transmitted to the PC 1.

Next, the DIR process will be described.
FIG. 15 is a flowchart showing the DIR process executed by the CPU 21 of the master ECR 2a. This process is a process realized by software processing in cooperation with the CPU 21 of the master ECR 2a and the DIR processing program stored in the recording device 27.

  When a DIR command is received from the PC 1 to browse the directory of the file storage memory of the RAM 23, the DIR table stored in the RAM 23 is referred to (step D1), and stored in the file storage memory based on the DIR table. The virtual directory storing the file name data accessible in the mode is created for each FTP mode (Step D2). ). Next, the file name data in the virtual directory corresponding to the current FTP mode stored in the FTP mode storage memory is converted into a format that can be output by the PC 1 (step D3). Then, the converted data is transmitted to the PC 1 via the first I / F of the transmission control unit 24 (step D4), and the process returns to step 1 in FIG.

  When the DIR command is received without specifying the FTP mode by the CD command, as shown in FIG. 16A, in step D3, data indicating a list of virtual directories created in step D2 is PC1. Is converted into a format that can be output by the PC 1 and transmitted to the PC 1.

  On the PC 1 side, the file name data of the file accessible in the current FTP mode of the master ECR 2 a can be acquired by the DIR command, so that the operation of the PC 1 can be performed by outputting the data received by the display device or the printer. The user can browse a list of file names that can be accessed in the current FTP mode of the master ECR 2a.

  For example, as shown in FIG. 16B, when the DIR command is transmitted from the PC 1 after the AUTOPGM mode is specified by the CD command, a list of file names accessible in the AUTOPGM mode can be displayed. Similarly, it is possible to display a list of file names accessible in the X mode, Z mode, and JOB mode.

[Example of processing sequence using FTP command]
Hereinafter, an example of a processing sequence between the PC 1 and the master ECR 2a using command transmission / reception by the FTP protocol will be described with reference to FIG. In FIG. 17, the FTP mode is designated to the master ECR 2a by the CD command from the PC 1, the list of file names accessible in the designated FTP mode is acquired and displayed by the DIR command, and the file name is designated by the GET command. This is a sequence for acquiring and displaying the contents of the designated file.

  In the PC 1, when the CD command and FTP mode are input by the operator via the input device 12 (step A1), the input CD command and FTP mode data are transmitted to the master ECR 2a (step A2).

  In the master ECR 2a, when the CD command is received via the first I / F of the transmission control unit 24 (step A3), the CD processing described in FIG. 14 is executed, and the FTP mode received together with the CD command. Is stored in the FTP mode storage memory (step A4).

  After changing the FTP mode of the master ECR2, when the DIR command is input by the operator via the input device 12 in the PC 1 (step A5), the DIR command is transmitted to the master ECR 2a via the transmission control unit 14. (Step A6).

  In the master ECR 2a, when the DIR command is received via the first I / F of the transmission control unit 24 (step A7), the DIR process shown in FIG. 15 is executed and stored in the FTP mode storage memory. File name data accessible in the FTP mode is created and transmitted to the PC 1 (step A8).

  In PC1, when file name data is received from master ECR 2a (step A9), a list of file names is displayed on display device 15 (step A10). When the operator inputs a GET command and a file name via the input device 12 (step A11), the input GET command and file name data are transmitted to the master ECR 2a (step A12).

  When the master ECR 2a receives the GET command and file name data (step A13), the GET process described in FIG. 13 is executed, and the file corresponding to the file name received together with the GET command is used in accordance with the FTP mode. The data is read out, converted into file data in the designated file format, and transmitted to the PC 1 (step A14).

  When the file data is received in the PC 1 (step A15), the contents of the file data are displayed on the display device 15 (step A15).

  With the above procedure, necessary file data of the master ECR 2a can be acquired from the PC 1 side and displayed on the display device 15.

[Sequence example of master ECR 2a and slave ECR 2b at start of counting process]
When the activation processing of various files is received from the PC 1 by the PUT command, the master ECR 2a needs to collect sales data from the slave ECR 2b. FIG. 18 shows an example of a processing sequence among the PC 1, the master ECR 2a, and the slave ECR 2b when the aggregation processing is activated by the PUT command from the PC 1 to the master ECR 2a. Hereinafter, the processing sequence of FIG. 18 will be described. Although the slave ECR 2b is illustrated as one unit, the master ECR 2a performs the same sequence as each slave ECR 2b connected to the communication network N2.

  In the PC 1, when the operator inputs the aggregation process activation command, that is, the name of the activation file storing the aggregation process activation command via the input device 12 (step B 1), the PUT command is input. The data of the activation file with the specified name is transmitted to the master ECR 2a (step B2).

  In the master ECR 2a, when the PUT command and the startup file are received via the first I / F of the transmission control unit 24 (step B3), the PUT process described in FIG. The tabulation process for the file designated in (1) is started (step B4), and it is determined whether or not it is the timing when the tabulation process can be currently performed (step B5). For example, the counting process cannot be started until a predetermined time, for example, the time when the store closes and the closing ends. If it is not the timing when the tabulation processing is possible (step B6; YES), an error code indicating that is stored in the response file 236. If it is possible to count (step B5; YES), the sales data collection command of the designated file is transmitted to the slave ECR 2b (step B7).

  When the slave ECR 2b receives the sales data collection command from the master ECR 2a (step B8), it is determined whether or not the sales data can be transmitted. If the sales data can be transmitted (step B9; YES), The sales data of the specified file is transmitted to the master ECR 2a, and the sales data of the file is cleared to zero and settlement is performed (step B10). When the sales data cannot be transmitted (for example, the power is OFF or the registration operation is in progress) (step B9; NO), an error code corresponding to the state is transmitted to the master ECR 2a (step B11). ).

  When the sales data is normally received in the master ECR 2a (step B12; YES), the received sales data is cumulatively added in the aggregation file corresponding to the designated file (step B13). If the sales data is not normally received and an error code is received (step B12; NO), the slave ID of the transmission source and the received error code are stored in the response file 236 (step B14).

  When the processing result reception command, that is, the GET command and the file name of the response file are input from the PC 1 (step B15), the data of the GET command and the file name of the response file are transmitted to the master ECR 2a (step B16).

  In the master ECR 2a, when the GET command and the file name data of the response file are received from the PC 1 (step B17), the GET processing is performed, the response file 236 is read, and converted into a format that can be output by the PC 1, It is transmitted to PC1 (step B18).

  In PC1, when response file 236 is received, it is displayed on display device 15 (step B19). If the error code is not included in the response file (step B20; NO), this process ends. If an error code is included (step B20; YES), a startup file is generated for the master ECR 2a with the startup command of the sales data collection process for the slave ECR 2b corresponding to the error code as data. Are transmitted together with the PUT command (step B21).

  When the master ECR 2a receives the PUT command and activation file data from the PC 1 (step B22), the sales data collection command is transmitted again to the slave ECR 2b based on the contents of the activation file (step B23). . When the slave ECR 2b receives the sales collection command, the processing from step B8 is executed again.

  With the above sequence, the PC 1 can cause the master ECR 2a to repeatedly collect data until there is no error slave ECR 2b.

[Modification]
FIG. 19 shows a modification of the series of processes described above. When a JOB start command is transmitted from the PC 1 to the master ECR 2a by FTP, the current operator in charge of the master ECR 2a executes the job in the master ECR 2a. The person-in-charge determining means for determining whether or not the person in charge is permitted is added, and if the person in charge is not authorized, a sequence in which a job activation from the PC 1 is an error is shown.

  In the PC 1, when an operator inputs a job start command, that is, a file name storing a PUT command and a job start command, via the input device 12 (step E 1), the PUT command and start of the input name are input. The file data is transmitted to the master ECR 2a (step E2).

  In the master ECR 2a, when the PUT command and the activation file are received via the first I / F of the transmission control unit 24 (step E3), the operator in charge of the current master ECR 2a (designated by the clerk key) It is determined whether or not the person in charge whose person-in-charge code is stored in the person-in-charge memory is the person in charge who is permitted to execute the job specified by the start-up file, and the execution of the specified job is permitted. If the person in charge is in charge (step E4; YES), the JOB is activated in accordance with the command of the activation file (step E5). If the current person in charge of the operation is not the person in charge who is permitted to execute the job specified by the startup file (step E4; NO), an error code indicating the person in charge error is stored in the response file 236 (step E6). ).

  When the processing result reception command, that is, the GET command and the file name of the response file are input from the operator via the input device 12 in the PC 1 (step E7), the file name of the GET command and the response file is input to the master ECR 2a. Data is transmitted (step E8).

  When the master ECR 2a receives the GET command and the data of the response file name from the PC 1 (step E9), the GET process is executed, and the response file 236 is read and converted into a format that can be output by the PC 1. Are transmitted to PC1 (step E10).

  In the PC 1, when the response file 236 is received, the contents of the response file are displayed on the display device 15 (step E11), and this process ends.

  With the above sequence, it becomes possible to execute a job only when the person in charge of operation on the master ECR 2a side is a person in charge of executing a job designated by the PC 1, such as a store manager. It is possible to prevent unauthorized termination of the job due to an erroneous operation by a store clerk or the like, and to ensure the security of data in the master ECR 2a. In the above modification, it is determined whether or not the person in charge is an authorized person when the JOB activation command is received. However, it is possible to switch to the Z mode with the deletion (clear) of sales data. When transfer is instructed, the person in charge may be similarly restricted.

  As described above, according to the master ECR 2a according to the present invention, when the data indicating the file name transmitted from the PC 1 is received, the data of the received file name is determined, and the data corresponding to the determined file name is determined. The data is read from the file storage memory of the RAM 23, the read data is converted into file data in a format specified by the received file name, and the converted file data is transmitted to the server PC1. Therefore, on the PC 1 side, the data format stored in the file storage memory of the master ECR 2a is stored in the file storage memory of the master ECR 2a and the data corresponding to the transmitted file name is specified in the PC 1 by simply transmitting the file name of the data to be acquired from the master ECR 2a. Can be received.

  In addition, when the master ECR 2a is in a non-processing state, the master ECR 2a reads data from the file storage memory according to the file name transmitted from the PC 1, so that unconfirmed data being processed is stored in the PC 1. It is possible to prevent errors such as transmission.

  Further, according to the master ECR 2a, when a command specifying the operation mode of the master ECR 2a at the time of communication based on the FTP protocol is received from the PC 1, the operation specified from the file data corresponding to the determined file name Only the data corresponding to the mode is read, and the read data is converted into file data in a format specified by the file name and transmitted to the PC 1. Therefore, only necessary data corresponding to the operation mode can be acquired from the file data designated on the PC 1 side.

  Further, according to the master ECR 2a, by specifying the Z mode from the PC 1 side and transmitting the sales data file name, it is possible to acquire the sales data and allow the master ECR 2a to settle the sales data. .

  In addition, according to the master ECR 2a, it is possible to determine whether or not the person in charge of the operation in the master ECR 2a is a person in charge of settlement, and in the case where the person in charge is permitted, the settlement can be performed. Data security can be ensured.

  Further, according to the master ECR 2a, the file data transmitted from the PC 1 is received, the file name and data content of the received file data are determined, and each of the data in the received file is determined in the file storage memory. The data is converted into a predetermined ECR format and written in an area corresponding to the file name and data content. Therefore, the file data transmitted from the PC 1 can be written in an appropriate area in an appropriate format determined by the master ECR 2a.

  Further, according to the master ECR 2a, the received file data is written when the master ECR 2a is in the non-processing state, so that it is possible to prevent an error from occurring during other processing in the master ECR 2a.

  In addition, the description content in the said embodiment is a suitable example of the ECR system 100 which concerns on this invention, and is not limited to this.

  For example, in the above embodiment, if the FPT mode is designated in advance, only data corresponding to the designated FPT mode is read from the file data corresponding to the received file name in the GET process. However, for example, when a file name is designated from the PC 1, an identification code indicating the desired data is added to the file name and transmitted, and the master ECR 2 a side identifies from the file corresponding to the file name received from the PC 1. Only data corresponding to the code may be read and transmitted to the PC 1. For example, when “FILE005X.TXT” is designated as the file name, only the data on the sales quantity and sales amount accessible in the X mode in the department file 231 (FILE005.DAT) may be transmitted to the PC 1. Good.

  In the above embodiment, the data processing apparatus of the present invention has been described as ECR. However, when file data is transmitted and received between a POS system server having a plurality of POS terminals and a POS terminal, the present invention is used. May be applied.

  In addition, the detailed configuration and detailed operation of the ECR system 100 can be changed as appropriate without departing from the spirit of the present invention.
