Next, an embodiment of the present invention will be described with reference to FIGS.
(Network scan system configuration)
FIG. 1 is a block diagram showing an electrical configuration of the network scan system of the present embodiment. This network scanning system includes a scanner device 1 (an example of an image reading device), a local computer 20 (an example of an information terminal device), a server computer 30 and the like that are connected to each other via a communication line 40. .

  The scanner device 1 is a multifunction machine having a scanner function, a printer function, a copy function, and the like, and includes a CPU 10 (an example of a control unit and a setting unit), a ROM 11, a RAM 12 (an example of a storage unit), and an NVRAM (nonvolatile memory). 13, hard disk drive 14 (an example of a storage unit), operation unit 15 (an example of an input unit, a sender identification unit, and a registration unit), a display unit 16, a printing unit 17, a reading unit 18 (an example of an acquisition unit), a network interface 19 (an example of an active login user specifying unit and a notification unit).

  The ROM 11 stores various programs for controlling the operation of the scanner device 1 such as a network scan process to be described later. The CPU 10 stores the processing results in the RAM 12 and the NVRAM 13 according to the program read from the ROM 11. The operation of the scanner device 1 is controlled. The hard disk drive 14 stores scan data and the like based on the output from the reading unit 18.

  The operation unit 15 includes a plurality of buttons, and various input operations such as an instruction to start printing can be performed by the user. The display unit 16 includes a liquid crystal display, a lamp, and the like, and can display various setting screens, operation states, and the like. The printing unit 17 prints an image on a recording medium such as paper. The reading unit 18 reads a document image and outputs image data. The network interface 19 is connected to a communication line 40, and mutual data communication is possible with an external local computer 20 and a server computer 30 that are also connected to the communication line 40.

  The local computer 20 includes a CPU 21 (an example of an authentication unit), a ROM 22, a RAM 23, a hard disk drive 24, an operation unit 25 having a keyboard and a pointing device, a display unit 26 having a liquid crystal display, and a network interface connected to a communication line 40. 27 etc. The hard disk drive 24 stores various programs such as a receiving application described later.

  Although not shown in detail, the server computer 30 has substantially the same configuration as the local computer 20, and includes a hard disk drive 31 (an example of a storage unit).

(Push scan processing and processing by receiving application)
Next, push scan processing executed in the scanner device 1 and various processing executed by the reception application in the local computer 20 will be described. FIG. 2 is a flowchart showing the flow of push scan processing executed in the scanner device 1. 3 and 4 are processes executed by the reception application in the local computer 20. FIG. 3 is a flowchart showing the flow of the user name response process, and FIG. 4 is a flowchart showing the flow of the scan data display process. is there.

  In the scanner device 1, when a user sets a document on the reading unit 3 and inputs a push scan execution instruction using the operation unit 15, the following push scan processing is started. When the push scan process is started, the CPU 10 first displays a screen for designating the local computer 20 that is the transmission destination of the scan data on the display unit 16 as shown in FIG. 2 (S101). Here, for example, since a plurality of computer names registered in advance are displayed on the display unit 16, the user selects and inputs the computer name of the other party to which the scan data is transmitted by the operation unit 15.

  When the computer name is designated by the user, the CPU 10 subsequently displays a screen for inputting the sender name on the display unit 16 (S102). Here, the user who wants to transmit scan data inputs his / her user name, in detail, a user name used when logging in to the local computer 20 to which the scan data is transmitted, through the operation unit 15.

  When the sender name is input, the active login user name (the logged-in user in the active state using the operation unit 25 or the display unit 26 among the logged-in users) is sent to the local computer 20 designated as the transmission destination. An inquiry signal for inquiring an active login user name is transmitted via the network interface 19 (S103). On the other hand, in the local computer 20, the user name response process shown in FIG. 3 is executed by the receiving application. When the CPU 21 receives the inquiry signal from the scanner device 1 (S201: Yes), the local computer 20 is logged in to the local computer 20. The user name of the user who is operating the local computer 20 (active login user name) is returned to the scanner device 1 (S202).

  When the CPU 10 of the scanner device 1 acquires the active login user name that is responded from the local computer 20 via the network interface 19, it determines whether or not the previously acquired sender name matches the active login user name. (S104). If the sender name and the active login user name match (S104: Yes), the reading unit 3 reads the document (S105). Then, based on the image data obtained by reading, for example, scan data (file) in the Tif format is generated (S106), and the scan data is transmitted to the local computer 20 designated as the transmission destination (S107). As a result, the scan data transmitted from the scanner device 1 is stored in a predetermined directory in the hard disk drive 24 of the local computer 20.

  In the local computer 20, the scan data display process shown in FIG. 4 is executed by the receiving application. When the CPU 21 receives the scan data (S301: Yes), the CPU 21 activates a predetermined viewer and displays an image of the scan data (S302). For this reason, when the sender who is the active login user of the local computer 20 returns to the location of the local computer 20, the contents of the scan data can be viewed immediately.

  If the sender name of the scan data does not match the active login user name of the destination local computer 20 in S104 of FIG. A password input screen is displayed (S108). Here, the user inputs a password for performing authentication when browsing the scan data later by the operation unit 15.

  Subsequently, the CPU 10 reads the document by the reading unit 3 (S109), generates scan data in, for example, PDF format based on the obtained image data, and sets the password input to the file (S110). ).

  The scan data is stored in a storage location registered in advance for each user (S111). The user can register the storage location for each user in advance using the operation unit 15, and the registration information is stored in the NVRAM 13. As the storage location, for example, a predetermined directory such as the hard disk drive 14 built in the scanner device 1 or the hard disk drive 31 of the server computer 30 can be designated.

  Next, the CPU 10 transmits a mail notifying the storage location (URL) of the scan data to the user whose user name is input as the sender via the network interface 19 (S112). It should be noted that the user name and its mail address are registered in advance in the NVRAM 13, and here, the mail addressed to the sender is transmitted by referring to it.

  As a result, the user who transmitted the scan data can grasp the storage location of the scan data by viewing the mail addressed to the user with the mail software when logging into the local computer 20 or the like. Then, when the scan data is acquired from the storage location and the user intends to browse with the PDF browsing application, the next PDF browsing process is executed.

(PDF browsing process)
FIG. 5 is a flowchart showing the flow of PDF browsing processing executed by the PDF browsing application in the local computer 20. The CPU 21 first determines whether a password is set in the scan data file (S401). If the password is set (S401: Yes), a password input screen is displayed on the display unit 26 (S402). . Therefore, when the password set by the user when transmitting the scan data is input (S403: Yes), or when the password is not set in S401 (S401: No), the file contents are displayed (S404). In this way, security can be ensured by performing password authentication on the scan data.

(Effect of this embodiment)
According to the present embodiment, the scan data is transmitted only when the sender of the scan data and the active login user of the local computer 20 of the transmission destination satisfy the specified condition (match). Thereby, it is possible to prevent the scan data from being browsed by a person who should not view the scan data, and to ensure security.

  If the scan data is not transmitted to the local computer 20 designated as the transmission destination, the scan data is stored in the hard disk drive 14 of the scanner device 1 or the hard disk drive 31 of the server computer 30 so that the user can scan. It is possible to save the trouble of performing scanning again to obtain data.

  In addition, when the scan data is not transmitted to the local computer 20 as the transmission destination, the scan data is stored in the built-in hard disk drive 14, so that the processing can be simplified as compared with the case where the scan data is stored outside. In addition, the stored scan data can be easily managed.

  In addition, when the scan data cannot be transmitted to the local computer 20 that is the original transmission destination, the scan data is stored in the registered storage destination, which is convenient.

  Further, the storage location of scan data when scan data is not transmitted to the original transmission destination can be registered in association with each sender. For this reason, an appropriate storage location can be registered for each user, such as selecting a location that is difficult for other users to see as a storage location of scan data, and convenience is improved.

  Further, when the scan data is stored in the hard disk drives 14, 31, etc., it is possible to prevent the scan data from being viewed by others by setting a password necessary for browsing the scan data.

  Further, by notifying the storage location when the scan data is stored in the hard disk drives 14, 31 and the like, it is possible to prevent a situation in which the sender of the scan data does not know the storage location of the scan data.
