In each case, a network is constructed by a LAN. In addition, although the management server and the router will be described for convenience of explanation, a plurality of management servers and routers may exist.

  FIG. 1 is a diagram schematically showing a system 1 according to the first embodiment. As shown in FIG. 1, in the image data transmission system 1, a management server 30 and a multifunction device 20 (22, 24) are connected via a router 40 via a LAN.

  These devices are connected by a wired or wireless LAN (for example, 1000BASE-T or IEEE802.11 a / b / n).

  The terminal device 10 is also connected to the LAN of the system 1. In this case, the router 40 has a wireless communication function, and the terminal device 10 also has a wireless communication function.

  That is, in the system 1 in FIG. 1, the management server 30 and the multi-function device 20 are connected by a wire using the router 40, and the user terminal is connected via a wireless LAN.

  In the present embodiment, the multi-function device 20 also has a function as a parent device of the wireless communication function. For example, communication is possible using any wireless LAN communication method such as IEEE 802.11 a / b / n, and the base station (base unit) has a function.

  In this case, the MFP 20 is assigned an SSID (Service Set Identifier). For example, the MFP 22 is assigned an SSID of “MFP_22”, and the MFP 24 is assigned an SSID of “MFP_24”. The terminal device 10 can be connected to the multi-function devices 22 and 24 by using the SSID.

Note that the stored information is an example, and information necessary for communication such as a gateway address and a proxy server address may naturally be stored. In addition, if printing is performed, a necessary printer driver or the like may be stored.

  The radio wave intensity table 154 is a table that stores the radio wave intensity with a connectable parent device. For example, as shown in FIG. 4, the radio wave intensity is stored in association with the SSID. The radio field intensity is acquired, for example, when communicating with the multifunction device 20 by wireless communication. For example, as shown in FIG. 4, the current radio wave intensity (eg, “High”) is stored in association with the SSID (eg, “MFP_22”).

  The image data 156 stores received image data and processed image data. Image data received via communication is stored, or image data processed by the image processing unit 140 is stored.

  The image forming unit 240 is a functional unit for the multifunction peripheral to operate as an image forming apparatus. For example, various functions such as an image printing unit that prints image data, a scanner unit that inputs a document and outputs it as image data, and a FAX unit that transmits an image to another multifunction device through a communication line can be realized. That is, functions such as a copy function, a scan function, and a FAX function that are executed as a general digital multifunction peripheral are realized.

Further, necessary setting values such as setting values of the multifunction device 20 and information related to connection are also stored.

  In addition, the storage unit 250 stores a state table 252 and transmission terminal information 254. Here, the state table 252 is a table that stores the state of the MFP 20 itself.

  For example, as illustrated in FIG. 6, the state table 252 is associated with a state of the wireless communication unit 230 of the multifunction device (for example, “parent device”) in association with the multifunction device name (for example, “multifunction device 22”). The table manages the SSID (for example, “MFP — 22”) and the IP address (for example, “192.168.0.22”) used for wireless connection.

  The transmission terminal information 254 stores an IP address related to a terminal device that transmits image data. For example, as shown in FIG. 7, if the IP address “192.168.0.10” is stored, the image data is transmitted to the terminal device “192.168.0.10”.

Here, the parent device management table 342 is a table that stores the state of the connected multifunction device 20, and the terminal management table 344 is a table that stores the state of the network terminal device. .

  For example, as shown in FIG. 9, the parent device management table 342 is associated with the multifunction device name (for example, “multifunction device 22”) and the state (for example, “parent device”) in the wireless control unit of the multifunction device 20. And an SSID used for wireless connection (for example, “MFP # 22”) and an IP address (for example, “192.168.0.22”).

  As shown in FIG. 10, the terminal management table 344 includes information on the terminal device, for example, the IP address (for example, “192.168.0.10”) of the terminal device located in the area of the SSID “MFP # 22”, The radio wave intensity (for example, “Middle”) when the terminal device receives is managed.

[1.2.4 router]
A functional configuration of the router 40 will be described with reference to FIG. As shown in FIG. 11, the router 40 includes a control unit 410, a communication unit 420, a wireless communication unit 430, a storage unit 440, and a terminal management unit 450.

For example, it manages identification information (IP address, MAC address, time when IP address is released, etc.), communication method, etc. of the terminal to be connected. It is also possible to acquire the radio field intensity of the connected terminal.

[1.3 Process flow]
Next, the flow of processing in this embodiment will be described with reference to FIG. First, the terminal device 10 acquires the radio field intensity from the connectable multifunction device 20. In the case of FIG. 12, the radio field intensity is acquired from the multifunction device 22 (S102) and the multifunction device 24 (S104). Note that the radio wave intensity can be acquired at any time as long as connection is possible.

  Subsequently, in the terminal device 10, the individual information is transmitted to the management server 30 (S108). Here, the individual information may be transmitted in association with the radio wave intensity acquired in S102 and S104 and the SSID, or the SSID having the strongest radio wave intensity may be transmitted. This individual information is transmitted to the management server 30 by an information transmission program (module) executed in the terminal device 10.

  The management server 30 specifies the IP address corresponding to the SSID from the parent device management table 342 based on the individual information. Then, the terminal information is transmitted to the parent device (multifunction device 22) having the specified IP address (S108). Here, the terminal information is transmitted including the IP address of the terminal device 10. The master device (multifunction device 22) that has received the terminal information can specify the terminal device 10 having the IP address as the transmission destination of the image data.

  The multi-function device 22 generates image data (S112), and transmits the image data to the terminal device having the highest radio wave intensity when transmitting the image (S114). In the case of this embodiment, the management server 30 notifies that the terminal device 10 is the strongest.

  Since the IP address of the terminal device 10 is acquired as the terminal information, the image data is transmitted to the IP address of the terminal device 10 (S114).

  The image data to be transmitted may be data scanned by the multifunction device 22 or image data selected arbitrarily. Further, it may be image data received from an external network.

  Here, the terminal device to be transmitted may display a list of detected terminal devices and select from the list, or may be automatically transmitted.

[1.4 Example of operation]
FIG. 13 shows an operation example in the present embodiment. FIG. 13 is a scene selection screen for selecting an image transmission destination. “PC — 010” displayed here indicates the terminal device 10 in the vicinity of the multifunction device 22.

  As described above, when image data is transmitted from the multifunction device 22, it is possible to automatically detect the transmission destination without being aware of the IP address of the terminal device 10. As a result, it is possible to automatically manage the terminal device as the transmission destination without performing an additional operation or the like no matter how many terminal devices increase.

  As an example of the usage method, for example, the user approaches the multi-function device 22 with the terminal device 10. Then, a method of use is conceivable in which image data of a read original is automatically transmitted to the terminal device 10 by performing a reading operation of the original with the multifunction device 22.

[2. Second Embodiment]
Next, the second embodiment will be described. 2nd Embodiment demonstrates embodiment at the time of increasing a terminal device. For example, as shown in the image data transmission system 2 of FIG. 14, a case where the terminal device 10 is increased to the terminal device 12 and the terminal device 14 will be described. The functional configuration of each device is the same as in the first embodiment. For example, the terminal device 12 acquires the radio field intensity of the multifunction device 22 (S202), and transmits individual information to the management server 30 (S206). Similarly, the terminal device 14 acquires the radio field intensity of the multifunction machine 22 (S204), and transmits the individual information to the management server 30 (S208). Further, although not shown in FIG. 15, the same processing may be executed for the multifunction device 24.

  Subsequently, the management server 30 transmits terminal information to the multi-function device 22 based on the received individual information (S210). The multi-function device 22 generates image data (S212), determines the transmission terminal, and then transmits the image data (S214 → S216). In this embodiment, the transmission terminal is determined as the terminal device 12 and transmitted. Here, several methods are conceivable as a method of determining the terminal device.

(1) When a plurality of pieces of individual information are included in the transmission terminal information As management information, the management server 30 transmits the received individual information to the multi-function device 22 including the radio field intensity of each terminal device. Here, the multi-function device 22 extracts the radio wave intensity from the received transmission terminal information, and displays a terminal device that can currently transmit. Then, the user selects the selected terminal device and transmits the image data. For example, as shown in FIG. 16, each terminal device is displayed as a destination list and selected. That is, in this case, the terminal device is selected by the user.

(2) When a plurality of pieces of individual information are not included in the transmission terminal information When the management server 30 receives the individual information, the terminal information having the highest radio wave intensity corresponding to the SSID is obtained from the radio wave intensity between the SSID and the terminal device. To the multifunction device. The multi-function peripheral transmits image data based on the received terminal information. In this case, image data is automatically transmitted even if the user does not select a terminal.

(3) When selecting the above operation Note that the above (1) and (2) can be operated in combination. That is, for example, if there is one terminal device connected to the multifunction peripheral, the behavior of (2), that is, image data is automatically transmitted to the connected terminal device. On the other hand, when a plurality of terminal devices are detected or a plurality of terminal devices having the same radio field intensity are detected, the behavior of (1), that is, the operation of allowing the user to select from the terminal devices is performed. Also good.

[3. Third Embodiment]
Next, a third embodiment will be described. In the third embodiment, an embodiment in which the number of multifunction peripherals is further increased will be described.

  In other words, as shown in the image data transmission system 3 of FIG. 17, in addition to the multifunction devices 22 and 24, the multifunction device 26 is connected to the network. As shown in FIG. 18, the multifunction device 26 stores the wireless state, the SSID, and the IP address of the multifunction device 26 as the state table 252.

  The management server 30 also stores information on the new multifunction device 26 in the parent device management table 342. For example, as shown in FIG. 19, the wireless state, the SSID, and the IP address are stored and managed for each multifunction device including the multifunction device 26.

  Then, the terminal device 10 detects the radio wave intensity for each SSID. At this time, the radio wave intensity table 154 stores and manages the radio wave intensity in association with each SSID, as shown in FIG. Then, the detected radio wave intensity is transmitted to the management server 30.

  The management server 30 identifies the multifunction device 20 from each SSID, and transmits terminal information to each multifunction device.

  As described above, according to the present embodiment, even when the multifunction device 20 is further added with a network, it can be detected on the network, and each time the terminal device or the multifunction device has a mutual IP address. There is an advantage that you can communicate without understanding.

[4. Fourth Embodiment]
Next, a fourth embodiment will be described. The fourth embodiment is an embodiment in which a portable terminal device 16 is added to the terminal device 12 as shown in the image data transmission system 4 of FIG.

  At this time, a priority is given to each terminal device. That is, when there is a portable terminal device, this method is effective when it is desired to receive the signal with priority.

  22 and 23 show states of the state table 152 stored in the terminal device 10, respectively. The “priority” is further stored in the state table 152 of the first embodiment. For example, FIG. 22 is a state table of the terminal device 12, and FIG. 23 is a state table of the terminal device 16.

  Here, in the state table of this embodiment, the priority is stored in addition to the wireless state and the IP address. That is, the management server 30 and the multi-function device 20 can determine the terminal device 10 that transmits image data based on the priority.

  For example, the priority stored in the state table of the terminal device 12 in FIG. 22 is “1”, and the priority stored in the state table of the terminal device 16 is “2”. When the priority is included in the individual information and transmitted, the multifunction device 20 and the management server 30 can select the terminal device 10.

  That is, it is possible to preferentially transmit image data to the terminal device 12 having a high priority. Thereby, for example, when the computer is not activated, an image is transmitted to the portable terminal device, but when the computer is activated, an image can be transmitted to the computer.

  Further, the terminal device 10 that transmits the image data together with the priority and the radio wave intensity may be determined. For example, when radio field strength is prioritized, image data is sent to a terminal device with higher radio field strength. The image data may be transmitted to a terminal device having a high level.

[5. Fifth Embodiment]
Subsequently, a fifth embodiment will be described. The fifth embodiment is an embodiment for performing user management. For example, as shown in the image data transmission system 5 of FIG. 24, consider a system in which terminal devices 12, 14, and 18 are connected. At this time, it is assumed that USER_12 is logged in to the terminal device 12, USER_14 is logged in the terminal device 14, and USER_18 is logged in the terminal device 18.

  The management server 30 further stores a user management table 346 as shown in FIG.

  An example of the user management table 346 is shown in FIG. As shown in FIG. 26, an image transmission authority (for example, “permission”) is stored in the user ID (for example, “USER — 12”).

  The multifunction device 20 determines a terminal device as a transmission destination based on the authority of image transmission at the stage of determining a terminal to transmit an image (for example, step S214 in FIG. 15). In addition, when the terminal information is transmitted, the management server 30 includes only the information of the terminal device that is authorized to transmit images in the terminal information.

  An example of the operation at this time is shown in FIG. For example, a terminal device that is not authorized to transmit while being detected as a terminal device that can be transmitted is grayed out and cannot be selected.

  For example, regarding “PC — 018”, since the authority to transmit images is “impossible”, transmission is impossible due to being grayed out.

[6. Sixth Embodiment]
Next, a sixth embodiment will be described. The sixth embodiment is an embodiment in which authority is set in more detail in the user management table 346 of the fifth embodiment.

  FIG. 28 shows a user management table 346 in the sixth embodiment. As shown in FIG. 28, in the user management table 346, what functions can be executed is set for each MFP.

  For example, in the multi-function device 22, the authority is set for each file type and each application. These authorities may be set not for each multifunction device but for each user who uses the multifunction device.

  Thus, according to the sixth embodiment, finer control can be performed by setting more detailed authority.

[7. Seventh Embodiment]
Next, a seventh embodiment will be described. In the above-described embodiment, the terminal device that transmits image data has been described as one unit. 7th Embodiment demonstrates the case where it transmits to a some terminal device.

  For example, as shown in FIG. 29, a button “all transmission” is displayed on the terminal device selection screen. When the user selects “all transmission”, the image data is transmitted to all currently displayed terminal devices.

  That is, for example, in the case of internal use, it can be realized that image data can be easily transmitted to all the departments.

  Here, as described in the fifth embodiment, it is possible to prevent unnecessary image data from being transmitted by combining access management.

[8. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.
