  If it is determined in the determination step of S206 that the information related to the registration information stored in the received packet is not stored in the registration information database (S206: NO), in S208, the CPU 21 registers information (transmission) from the received packet. First name, application software name, IP address, port number, timeout value, encrypted registration verification information: there may be no encrypted registration verification information). Then, the CPU 21 sets the transmission destination to USB, and stores the name, IP address, port number, timeout value of the application software included in the extracted registration information, and in some cases, the encrypted registration verification information in the registration information database. to add. As a result, the IP address of the personal computer that transmitted the packet is associated with the registration verification information given to the personal computer and encrypted and registered in the registration information database. Then, the process proceeds to S209. Since the transmission destination of the registration information database is USB, the name of the personal computer included in the registration information is not registered in the registration information database.

  In S <b> 209, the CPU 21 determines whether a packet storing registration information is received via the parallel interface 29. If it is determined that a packet has been received via the parallel interface 29 (S209: YES), the process proceeds to S210. On the other hand, when it is determined that no packet is received via the parallel interface 29 (S209: NO), the process returns to S201.

  If it is determined in the determination step of S209 that the packet has been received via the parallel interface 29 (S209: YES), in S210, the CPU 21 receives the registration information database stored in the RAM 23 in the registration information database shown in FIG. Information related to the registration information stored in the received packet (transmission destination name, application software information, IP address, port number, encrypted registration verification information: there may be no encrypted registration verification information). It is determined whether it has already been stored. If it is determined that the information related to the registration information stored in the received packet is already stored in the registration information database (S210: YES), the process proceeds to S211. On the other hand, when it is determined that the information related to the registration information stored in the received packet is not stored in the registration information database (S210: NO), the process proceeds to S212.

  If it is determined that the information related to the registration information stored in the received packet is already stored in the registration information database in the determination step of S210 (S210: YES), in S211, the CPU 21 receives the registration received from the registration information database. Update the timeout value of information related to information to the timeout value included in the received registration information. Then, the process returns to S201.

  If it is determined in the determination step of S210 that the information related to the registration information stored in the received packet is not stored in the registration information database (S210: NO), in S212, the CPU 21 transmits registration information (transmission) from the received packet. First name, application software name, IP address, port number, timeout value, encrypted registration verification information: there may be no encrypted registration verification information). Then, the CPU 21 sets the transmission destination to Parallel and adds the application software name, IP address, port number, timeout value, and in some cases encrypted registration verification information included in the extracted registration information to the registration information database. To do. As a result, the IP address of the personal computer that transmitted the packet is associated with the registration verification information given to the personal computer and encrypted and registered in the registration information database. Then, the process proceeds to S201. Since the transmission destination of the registration information database is Parallell, the name of the personal computer included in the registration information is not registered in the registration information database.

  Hereinafter, the registration information deletion process performed in the data processing system 1 will be described with reference to FIG. FIG. 7 is a flowchart showing an operation flow of registration information deletion processing performed by the scanner 2 constituting the data processing system 1. The registration information deletion process shown in FIG. 7 is started by reading the above-described registration information deletion process program from the ROM 22 by the CPU 21 of the scanner 2 when the power of the scanner 2 is turned on.

  In S301, the CPU 21 of the scanner 2 determines whether or not there is registration information that has timed out (registration information whose timeout value has reached 0) in the registration information database illustrated in FIG. If it is determined that there is registration information that has timed out (S301: YES), the process proceeds to S302. On the other hand, if it is determined that there is no registration information that has timed out (S302: NO), the process returns to S301.

  In S302, the CPU 21 deletes the time-out registration information from the registration information database. Then, the process returns to S301.

  Hereinafter, image data processing performed in the data processing system 1 will be described with reference to FIG. FIG. 8 is a flowchart showing an operation flow of image data processing performed by the scanner 2 constituting the data processing system 1. The execution of the image data processing of FIG. 8 is started by reading the above-described image data processing program from the ROM 22 by the CPU 21 of the scanner 2 by a predetermined user key operation on the operation panel 25 of the scanner 2.

  In step S <b> 401, the CPU 21 of the scanner 2 accesses a registration information database stored in the RAM 23. Then, the process proceeds to S402. In S401, in addition to accessing the registration information database stored in the RAM 23, it may be possible to access registration information registered in the directory server.

  In S402, the CPU 21 determines which of the number of transmission destinations of the registration information database and the number of application software is smaller. When it is determined that the number of application software is small (S402: application), the process proceeds to S403. On the other hand, when it is determined that the number of transmission destinations is small or the same (S402: transmission destination), the process proceeds to S407.

  For example, in the case of the registration information database shown in FIG. 3A, the number of application software (Scan to Email, Scan to Image, Scan to OCR) is three, and the destinations (PC1, PC2, PC3, USB, Since the number is less than five (S402: application), the process proceeds to S403. In the case of the registration information database shown in FIG. 3B, the number of transmission destinations (PC3, USB) is two, and the number of application software (Scan to Email, Scan to Image, Scan to OCR) is three. Since there are fewer than two (S402: transmission destination), the process proceeds to S407.

  If it is determined in the determination step of S402 that the number of application software is smaller (S402: application), in S403, the CPU 21 sets the application software selection group on the left side of the screen as shown in FIG. 4A. A selection screen in which a terminal device selection group (information on the terminal device is not displayed at this stage) is arranged on the right side of the screen is displayed. The application software displayed in this application software selection group is only that existing in the registration information database. However, the selection screen at this stage is controlled by the CPU 21 so that it can be selected only from the application software selection group on the left side of the selection screen. Then, the process proceeds to S404.

  In S404, the CPU 21 determines whether application software has been selected by the user using the application software selection group on the selection screen displayed in the process of S403. If it is determined that the application software has not been selected (S404: NO), the process returns to S404 to monitor the selection of the application software by the user. On the other hand, if it is determined that the application software has been selected, (S404: YES), the process proceeds to S405.

  In S405, the CPU 21 displays only the transmission destination related to the application software selected by the user on the terminal device selection group on the selection screen based on the registration information database illustrated in FIG. Then, the process proceeds to S406.

  For example, if the registration information database is shown in FIG. 3A and Scan to Email is selected in the application software selection group on the selection screen in FIG. 4A, it is displayed in the terminal device selection group on the selection screen. As shown in FIG. 4B, the transmission destinations are PC1 and <USB>.

  In S406, the CPU 21 determines whether a transmission destination is selected by the user using the terminal device selection group on the selection screen displayed in the process of S405. If it is determined that the transmission destination is not selected (S406: NO), the process returns to S406, and the selection of the transmission destination by the user is monitored. On the other hand, if it is determined that the selection destination has been selected (S406: YES), the process proceeds to S411.

  If it is determined in the determination step of S402 that the number of transmission destinations is smaller or the same (S402: transmission destination), in S407, the CPU 21 selects a terminal device selection group as shown in FIG. 4C. On the left side of the screen, a selection screen in which an application software selection group (information on the application software is not displayed at this stage) is arranged on the right side of the screen is displayed. The destinations displayed in this terminal device selection group are only those existing in the registration information database. However, the selection screen at this stage is controlled by the CPU 21 so that only the terminal device selection group on the left side of the selection screen can be selected. Then, the process proceeds to S408.

  In S408, the CPU 21 determines whether a transmission destination is selected by the user using the terminal device selection group on the selection screen displayed in the process of S407. If it is determined that the transmission destination is not selected (S408: NO), the process returns to S408 to monitor the selection of the transmission destination by the user. On the other hand, if it is determined that the transmission destination is selected, (S408: YES), the process proceeds to S409.

  If it is determined in the determination step of S408 that the transmission destination has been selected (S408: YES), in S409, the CPU 21 selects the application software selection group on the selection screen based on the registration information database shown in FIG. Only the application software related to the destination selected by the user is displayed. Then, the process proceeds to S410.

  For example, when the registration information database is shown in FIG. 3B, and the PC 3 is selected in the terminal device selection group on the selection screen in FIG. 4C, the application displayed in the application software selection group on the selection screen. The software is Scan to Image and Scan to OCR as shown in FIG.

  In step S410, the CPU 21 determines whether application software has been selected by the user using the application software selection group on the selection screen displayed in step S409. If it is determined that the application software is not selected (S410: NO), the process returns to S410, and the selection of the application software by the user is monitored. On the other hand, if it is determined that the application software has been selected (S410: YES), the process proceeds to S411. The CPU 21 that executes the processes from S401 to S410 corresponds to a terminal determination unit and an application software determination unit.

  In S411, the CPU 21 determines whether or not the encrypted registration verification information corresponding to the transmission destination selected by the user is in the registration information database illustrated in FIG. If it is determined that the encrypted registration verification information is in the registration information database (S411: YES), the process proceeds to S412. On the other hand, if it is determined that there is no encrypted registration verification information (S411: NO), the process proceeds to S415.

  If it is determined that there is encrypted registration verification information in the determination step of S411 (S411: YES), in S412, the scanner 2 is controlled by the CPU 21 to request the user to input the input verification information, and the CPU 21 Determines whether input collation information has been input by the user using the operation unit of the operation panel 25. If it is determined that the input verification information has not been input by the user (S412: NO), the process returns to S412 to monitor the input verification information input by the user. On the other hand, when it is determined that the input collation information has been input by the user (S412: YES), the process proceeds to S413.

  If it is determined in the determination step of S412 that input collation information has been input (S412: YES), in S413, the CPU 21 substantially converts the input collation information into an encryption process in which the registered collation information is encrypted. Encrypt based on the same encryption process. Then, the process proceeds to S414.

  In S414, the CPU 21 determines whether or not the input collation information encrypted in the process of S413 matches the encrypted registration collation information stored in the registration information database corresponding to the selected transmission destination. Determine. If it is determined that both match (S414: YES), the process proceeds to S415. On the other hand, if it is determined that the two do not match (S414: NO), the image data processing is terminated. That is, transmission of the image data to the selected transmission destination is refused.

  In S415, the CPU 21 is connected to an IP address stored in the registration information database of the personal computer or the personal computer to the personal computer of the transmission destination selected from the terminal device selection group by the user. The registration information of the application software selected from the application software selection group by the user is notified using USB or parallel. Then, the process proceeds to S416. The CPU 21 that executes the process of S415 corresponds to a notification unit and a request transmission unit.

  In step S <b> 416, the reading unit 26 is controlled by the CPU 21 to read the set original, and stores image data generated by the reading in the HDD 30. Then, the process proceeds to S417.

  In S417, the CPU 21 determines whether or not a notification from the personal computer of the transmission destination selected by the user from the terminal device selection group has been received. If it is determined that a notification from the transmission destination personal computer has not been received (S417: NO), the process returns to the processing of S417, and the reception of the notification from the transmission destination personal computer is monitored. On the other hand, if it is determined that a notification from the personal computer of the transmission destination has been received (S417: YES), the process proceeds to S418.

  In S418, the CPU 21 determines whether or not the notification content from the transmission destination personal computer received in S417 is a data transmission request. If it is determined that the notification content from the personal computer of the transmission destination is not a data transmission request (S418: NO), the process proceeds to S420. On the other hand, when it is determined that the notification content from the personal computer of the transmission destination is a data transmission request (S418: YES), the process proceeds to S419.

  In S419, the CPU 21 connects the IP address stored in the registration information database of the personal computer or the personal computer to the personal computer of the transmission destination selected by the user using the terminal device selection group. In step S416, the image data stored in the HDD 30 is read out and transmitted using the USB or parallel. Thereafter, the process proceeds to S420. The CPU 21 that executes the process of S419 corresponds to a data transmission unit.

  In S420, the CPU 21 deletes the image data stored in the HDD 30 in S416 from the HDD 30, and ends the image data processing.

  Hereinafter, image data processing performed in the data processing system 1 will be described with reference to FIG. FIG. 9 is a flowchart showing an operation flow of image data processing performed by the personal computers 3, 4, 5 a, 5 b and 5 c constituting the data processing system 1. The execution of the image data processing in FIG. 9 is started when the personal computer 3, 4, 5a, 5b, 5c is powered on and the like by reading the above-described image data processing program from the HDD 34 by the CPU 31 of the personal computer.

  In step S <b> 501, the CPU 31 determines whether a notification of registration information of application software to be activated has been received from the scanner 2. If it is determined that the notification of the registration information of the application software to be activated has not been received from the scanner 2 (S501: NO), the process returns to the process of S501 to monitor the reception of the registration information of the application software. On the other hand, if it is determined that the notification of registration information of the application software to be activated has been received from the scanner 2 (S501: YES), the process proceeds to S502. The CPU 31 that executes the processing of S501 corresponds to a notification receiving unit and a request receiving unit.

  In S <b> 502, the CPU 31 displays a confirmation dialog for starting scanning by the scanner 2 in a pop-up window. In the confirmation dialog, a button for selecting whether to permit the start of scanning, an input frame for inputting a time for receiving the image data generated by the scanning of the scanner 2, and a determination for determining the input contents for the confirmation dialog Button is displayed. Note that the scan 2 does not wait for permission to start scanning, but first starts scanning, generates image data, stores it in the HDD 30, and waits (see S415 and S416 in FIG. 8). This is to shorten the time until image data is received. Then, after the confirmation dialog is displayed, the process proceeds to S503.

  In S503, the CPU 31 determines whether or not there is an input based on a user operation in the confirmation dialog displayed in S502. Whether or not there is an input based on the user's operation in the confirmation dialog is determined by whether or not the confirmation dialog decision button has been pressed by the user. If it is determined that there is no input based on the user's operation in the confirmation dialog (S503: NO), the process returns to S503 to monitor the input based on the user's operation on the confirmation dialog. On the other hand, when it is determined that there is an input based on the user's operation in the confirmation dialog (S503: YES), the process proceeds to S504. The CPU 31 that executes the processes from S502 to S503 corresponds to a determination unit.

  In step S <b> 504, the CPU 31 determines whether or not permission to start scanning by the scanner 2 is input to the confirmation dialog based on the user operation. If it is determined in the confirmation dialog that permission to start scanning by the scanner 2 has not been input based on the user's operation (S504: NO), the process proceeds to S505. In S <b> 505, the CPU 31 notifies the scanner 2 of data transmission rejection. After notifying that data transmission has been rejected, the image data processing is terminated. Note that the CPU 31 that executes the processing of S505 corresponds to permission notification transmission means.

  On the other hand, if it is determined in the confirmation dialog that permission to start scanning by the scanner 2 is input based on the user's operation (S504: YES), the process proceeds to S506.

  In S506, the CPU 31 activates the application software to be activated indicated by the notification content received from the scanner 2 in S501. When the activation of the application software to be activated is completed, the process proceeds to S507.

  In step S <b> 507, the CPU 31 notifies the scanner 2 of data transmission permission. Then, the process proceeds to S508. The CPU 31 that executes the process of S507 corresponds to a permission notification transmission unit.

  In step S <b> 508, the CPU 31 determines whether image data has been received from the scanner 2. If it is determined that no image data has been received (S508: NO), the process returns to S508 to monitor the reception of the image data. On the other hand, if it is determined that the image data has been received (S508: YES), the process proceeds to S509. The CPU 31 that performs the process of S508 corresponds to a data receiving unit.

  In step S509, the CPU 31 processes the image data received from the scanner 2 using application software activated in step S506. Then, after the processing is completed by the activated application software, the image data processing is ended. The CPU 31 that performs the process of S509 corresponds to a processing unit.

  As described above, according to the data processing system 1 of the present embodiment, the scanner 2 transmits image data after receiving a data transmission permission notification from the personal computers 3, 4, 5a, 5b, and 5c. It is possible to prevent the personal computers 3, 4, 5a, 5b, and 5c from receiving image data not intended by the user by a simple operation of the user.

  In addition, since the personal computer 3, 4, 5a, 5b, 5c also serves as a data transmission permission notification from the scanner 2 indicating the application software to be activated, it is possible to reduce traffic and personal Since the data transmission permission notification is transmitted after the application software is confirmed on the computer 3, 4, 5 a, 5 b, 5 c side, it is possible to find an application software designation error on the scanner 2 side.

  Further, it is possible to send an e-mail with image data attached to the personal computer 3, 4, 5a, 5b, 5c, edit the image data, or perform character recognition from the image data.

  Furthermore, since the scanner 2 includes a storage device such as the RAM 23 and the HDD 30, the system can be simplified.

  In addition, since the user designates specific personal computers 3, 4, 5 a, 5 b, 5 c and application software from the personal computer group and application software group displayed on the scanner 2 by the user's operation, an error in data due to a designation mistake Transmission can be reduced.

  In addition, a plurality of image data to be transmitted by the scanner 2 can be stored in the HDD 30. As a result, other image data can be generated while waiting for a data transmission permission notification from the personal computers 3, 4, 5a, 5b, and 5c.

  In addition, when the user is notified of the application software, the user can select whether or not to send the data transmission permission notification through the confirmation dialog, and thus the security can be increased by a simple operation of selecting.

  Furthermore, since the transmission start time of the image data can be designated, the data can be received at a time convenient for the personal computers 3, 4, 5a, 5b, and 5c.

  The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various design changes can be made as long as they are described in the claims. . For example, in the above-described embodiment, the scanner 2 is used as an example of the image data generation device, but other devices such as a digital camera may be used. As examples of application software, Scan to Email, Scan to Image, and Scan to OCR are described as examples. However, application software that scans image data by fax (Scan to FAX) is also available. Also good.

  In the above embodiment, the image data generated by the scanner 2 is processed. However, the present invention is not limited to this, and the structure that processes moving image data, audio data, text data, other application data, and the like. But you can.

  Furthermore, in the above-described embodiment, the notification of the registration information of the application software from the scanner 2 is also configured to function as a data transmission permission request. The data transmission permission request may be transmitted separately.

  In addition, in the above embodiment, the registration information database is stored in the RAM 23 of the scanner 2. However, the registration information database is not stored in the RAM 23 of the scanner 2 and can be accessed by communication instead. A database server may be prepared, and a registration information database may be stored in the database server. Alternatively, the registration information database of the personal computer or application software may be stored in the RAM 23 of the scanner 2, and the other registration information database may be stored in the database server. The configuration may be stored in the memory. Moreover, the structure which does not use a registration information database may be sufficient. In this case, identification information of the personal computer and application software may be input individually.

  In the above embodiment, the scanner 2 is configured to have a function of allowing the user to select a personal computer as a transmission destination and application software for processing image data. 2 may be provided, and another personal computer may be provided. In addition, the scanner 2 and other personal computers may not have such a function. In this case, the destination personal computer and application software for processing the image data may be designated by setting or the like.

  In the above embodiment, the HDD 30 for storing the image data generated by the scanner 2 is provided. However, the present invention is not limited to this, and a configuration without a storage device such as the HDD 30 may be used.

  Furthermore, in the above embodiment, the personal computers 3, 4, 5a, 5b, and 5c are configured to determine whether or not to notify permission of data transmission based on the user input to the confirmation dialog. Instead, it may be determined based on a preset setting without requiring user input each time.

  In addition, in the above embodiment, the personal computers 3, 4, 5a, 5b, and 5c are configured to designate the transmission timing of the image data when notifying the permission of data transmission. A configuration in which the timing is not specified may be used. In this case, the scanner 2 may transmit the image data immediately upon receiving the data transmission permission, and further notify the command instructing image data transmission from the personal computers 3, 4, 5a, 5b, and 5c. Then, the image data may be transmitted.

  In the above embodiment, the personal computers 3 and 4 connected by the USB and parallel I / F of the scanner 2 and the personal computers 5a, 5b and 5c connected to the LAN 8 together with the scanner 2 are provided. However, the present invention is not limited to this, and a configuration having only a personal computer connected to the USB or parallel I / F of the scanner 2 or a configuration having only a personal computer connected to the LAN 8 together with the scanner 2 may be used.

  Furthermore, in the above embodiment, registration information (name of destination, application software information, IP address, port number, timeout value) is received from the personal computer based on the registration information transmission processing executed by the personal computer shown in FIG. Is transmitted to the scanner, and the registration information database shown in FIG. 3 is created by the scanner, and the terminal information and application software are selected using this registration information database. You may go by.

  For example, as described above, without transmitting registration information including a destination name, application software information, an IP address, a port number, and a timeout value at a time, the registration information is transmitted to the registration information (transmission destination regarding the terminal device). Name, IP address, port number, etc.) and registration information (application software information, etc.) relating to the application software, and sending the registration information relating to the terminal device from the personal computer to the scanner first. When the terminal device is selected by the scanner, the selected terminal device is inquired based on the information included in the registration information, and the application software obtained by the inquiry is registered. Select application software based on information It may be.

  This configuration will be described in more detail. In place of the registration information transmission process shown in FIG. 5 of the above embodiment, a registration information transmission process as shown in FIG. 11 may be executed instead of the image data processing shown in FIG. 8 (the processing based on the other drawings is basically the same, and detailed description thereof is omitted). . That is, when the registration information transmission processing program shown in FIG. 10 is executed by reading the registration information transmission processing program from the HDD 34 by the CPU 31 of the personal computer 3, 4, 5a, 5b, 5c when the power is turned on. First, in S601, the CPU 31 registers information relating to the terminal device (<IP address of own device>: <port number>: <name of own device (content stored in transmission destination of registration information database: name of transmission destination). > Etc.), and the personal computer is controlled by the CPU 31 to transmit registration information relating to the created terminal device to the scanner 2. Since the scanner 2 receives registration information related to the terminal device, the registration information database updated in the process of FIG. 6 does not include information indicating application software.

  In step S602, it is determined whether an inquiry about application software that can be used is received from the scanner 2 in step S704 described later. And when it is judged that the said inquiry was received (S602: YES), it transfers to S603. On the other hand, if it is determined that the inquiry has not been received (S602: NO), the process returns to S602 and the application software inquiry is monitored.

  In S603, the CPU 31 performs substantially the same processing as S101 to S106 shown in FIG. 5 (however, the registration information created and transmitted to the scanner 2 is registration information related to application software). Then, registration information relating to application software (<IP address of own device>: <information indicating application software>) is created, and the personal computer transmits the registration information relating to the created application software to the scanner 2 under the control of the CPU 31. .

  On the other hand, in the scanner 2, the image data processing program shown in FIG. 11 is read from the ROM 22 by the CPU 21 of the scanner 2 by the user's predetermined key operation on the operation panel 25 of the scanner 2, and the image data processing is executed. Then, processes substantially similar to S401, S407, S408, S409, S410, S411, S412, S413, and S414 shown in FIG. 8 (however, different processes are performed between S409 and S704 as described later). Are executed in S701, S702, S703, S704, S705, S706, S707, S708, and S709 in FIG.

However, S704 is significantly different from S409. Here, the personal computer (terminal device) selected in S703 is registered with the personal computer using the registration information regarding the terminal device stored in the registration information database. in intends line inquiries about available application software. As a result, in step S603 described above, the application software that can be used in the personal computer is notified from the personal computer by the registration information related to the application software, and the scanner 2 displays a display based on the notification on the operation panel 25. For example, the display as shown in FIG. 4B or FIG. 4D is performed.

  According to the above configuration, for example, since it is not necessary to register which application software can be used by which personal computer (terminal device) in the registration information database, it is easy to manage and registration information related to the terminal device. Therefore, it is possible to reduce the load on the memory.

  In addition, each program that causes the scanner 2 or a personal computer to execute the above-described contents may be recorded on various recording media such as a CD-ROM that can be read by the computer.
