Specifically, the touch screen 105 is realized by positioning and fixing the touch panel 1052 on the display 1051 (for example, a liquid crystal display). The touch screen is also referred to as a touch panel display, a display with a touch panel, or a touch panel monitor. In the touch screen 105, for example, a resistance film method or a capacitance method can be used as a method for detecting the touch position.

Various data such as image data are stored in the storage unit 104. The storage unit 104 is, for example, an HDD which is a non-volatile semiconductor memory.

The speaker 106 generates sound in response to a command from the CPU 101. The network communication IF 108 can communicate with various external devices 20 via the network 30. External devices connectable to network 30 include, for example, PCs, Internet faxes, and other MFPs. The G3FAX communication IF can communicate with the G3FAX as the external device 20 by using a telephone line.

Further, the image input unit 110 receives an input of image data from the user. For example, the user converts an image to be input to the MFP 15 into image data by the scanning function of the MFP 15 and inputs the image to the MFP 15.

The touch panel 1052 is an input device that accepts input (touch input) by a user's finger or the like. The CPU 101 specifies an input position based on the output from the touch panel 1052, and displays a screen based on the specified input position.

[About the flow of image data]
Next, the flow of image data will be described with reference to FIG. As a step (A), the storage unit 104 stores the image data received by the MFP 15. This image data is, for example, data transmitted from the external device 20.

Next, as a step (B), the MFP 15 executes a virus check on the image data stored in the storage unit. A brief description of virus checking. As an example of a virus to image data, there is a malicious program (malicious JAVA (registered trademark) Script, etc.) in the alpha channel of image data such as PDF. In general, it is difficult for a virus to intervene in the main body of the image data itself among the image data. The virus check can be executed if the image data is composed of, for example, a main body portion (JPEG image) containing virus data and an extraction program for extracting a code from the image. Hereinafter, the fact that the virus check is completed without detecting the virus in the virus check is referred to as "the virus check is completed".

When it is determined that the virus check has been completed, as step (C), the image data for which the virus check has been completed is output based on the transmission designation from the user or the like.

In the example of FIG. 3, the process of outputting image data includes a process of printing an image based on the image data (step (C-1)). The process of outputting image data is a process of transmitting by E-mail, a process of transmitting to an FTP (File Transfer Protocol) server, a process of transmitting to an SMB (Server Message Block) server, and a process of transmitting to G3 FAX (step).

Further, the process of outputting the image data includes a process (step (C-4)) of displaying the image based on the image data on the browser of the external device 20 by transmitting the image data to the external device 20.

[Functional configuration example of MFP15, etc.]
Next, a functional configuration example of the MFP 15 and the like will be described with reference to FIG. The MFP 15 or the data transmission device 10 included in the MFP 15 includes a storage unit 104, a virus check unit 130, a determination unit 132, a control unit 134, a display unit 138, and a communication unit 136.

As described in FIG. 3 and the like, the storage unit 104 stores data such as image data. The virus check unit 130 performs a virus check on the image data stored in the storage unit 104. The virus check method may be any method. Further, the virus check is required for a period according to the type of the virus check process and the type / capacity of the image data.

Further, the transmission designation is input to the MFP 15. Here, the transmission designation includes a transmission designation input by the user from the operation unit (operation key 107, touch panel 1052, etc.) of the MFP 15. This transmission designation includes designation of image data desired to be transmitted by the user, designation of a transmission destination of the image data, and the like.

Further, the transmission designation also includes a designation input from the external device 20. For example, the transmission designation is input to the external device 20 by the user, and the transmission designation is input from the external device 20 to the MFP 15. This transmission designation also includes designation of image data desired to be transmitted by the user, designation of a transmission destination of the image data, and the like.

Hereinafter, a case where the external device 20 transmits the transmission designation to the MFP 15 by the user's operation will be described. When the transmission designation is input to the MFP 15, the determination unit 132 determines the execution status of the virus check for the image data designated by the transmission designation. Here, the execution status of the virus check includes (a) the situation where the virus check is not executed in the first place (the situation where it is not executed), (b) the situation where the virus check is being executed, and (c) the virus check. It includes the situation where the virus check is completed and the virus check result is undetected, and (d) the virus check is completed and the virus check result is the virus detected.

In the following, "(a) the situation where the virus check has not been executed in the first place (the situation where it has not been executed) and (b) the situation where the virus check is being executed" are summarized as "the virus check has not been completed". Or "virus check is incomplete". Further, (c) the situation where the virus check is completed and the virus check result is that the virus has not been detected is called "virus check completed". Further, (d) a situation in which a virus check is completed and a virus is detected as a result of the virus check is referred to as "a virus is detected by the virus check".

When the determination unit 132 determines that the virus has been detected by the virus check, the communication unit 136 transmits virus detection information indicating that the virus has been detected by the virus check to the external device 20. The external device 20 is an external device designated by the transmission designation that triggers the determination process of the determination unit 132 to be executed.

Upon receiving the virus detection information, the external device 20 notifies that the virus has been detected. This notification means, for example, displaying an image indicating that a virus has been detected on the display unit 206 or the like. This image is, for example, an image of the characters "virus detected".

The display unit 138 of the MFP 15 may display an image indicating that a virus has been detected.

When the determination unit 132 determines that a virus has been detected by the virus check, the MFP 15 notifies that the virus has been detected. This notification means, for example, displaying an image indicating that a virus has been detected on a display or the like. This image is, for example, an image of the characters "virus detected".

When the determination unit 132 determines that the virus check has been completed, the image data is transmitted to the external device 20. This image data is image data for which it is determined that the virus check has been completed. The external device 20 is an external device designated by the transmission designation that triggers the determination process of the determination unit 132 to be executed. As a result, the external device 20 can receive the image data for which the virus check has been completed, that is, the safe image data.

The communication unit 202 of the external device 20 receives the image data transmitted from the MFP 15 as a receiving unit. When the communication unit 202 receives the image data, the control unit 210 displays the image based on the image data on the display unit 206. In the present embodiment, the image based on the image data is a thumbnail image of the image data (see FIG. 6). As a result, the user can recognize that the external device 20 has received the desired image data. Further, the control unit 210 may store the received image data in the storage unit 204.

When the determination unit 132 determines that the virus check has not been completed, the control unit 134 sends the access information to the external device 20 without transmitting the image data determined that the virus check has not been completed. It is transmitted via the communication unit 136 (first transmission unit).

Here, the access information may be any information as long as it is information that can be accessed by the external device 20 with respect to the image data stored in the storage unit 104. The access information may be, for example, link information (for example, an address) of the storage unit 104. Further, the access information may be the address of the image data desired by the external device 20 among the image data stored in the storage unit 104. Hereinafter, the access information will be described as "link information of the storage unit 104". The address may be any address such as an IP address or a MAC address.

When the communication unit 202 of the external device 20 receives the link information of the storage unit 104, the control unit 210 causes the display unit 206 to display the link information. FIG. 5 is a diagram showing an example of link information displayed in the display area 206A of the display unit 206.

In the example of FIG. 5, the link information 2060 and the pointer 2062 are displayed together with the characters "link to BOX". By displaying this link information 2060, the external device 20 informs the user that the virus check of the image data designated by the transmission designation has not been completed when the transmission designation is input to the MFP 15. Can be recognized.

Further, the link information 2060 is displayed in a mode that can be specified by the user's operation on the operation unit 212. Next, the designation to the link information 2060 will be described.

When the external device 20 is a PC, the operation unit 212 is, for example, a mouse and a keyboard. The user operates the mouse to move the pointer 2062 to a position where it overlaps with the link information 2060. When the pointer 2062 is moved to a position where it overlaps with the link information 2060, the user can specify the link information 2060 by clicking the mouse.

When the external device 20 is a smartphone or a tablet, the link information 2060 is displayed, but the pointer 2062 is not displayed. The user can specify the link information 2060 by touching the link information 2060.

When the link information 2060 is specified by the user, the control unit 210 of the external device 20 generates the request information and transmits the request information to the MFP 15. Here, the MFP 15 is an MFP 15 having a storage unit 104 specified from the designated access information. Further, the request information is information for requesting image data for which the virus check is determined to be incomplete by the determination unit 132. In the following, the requested image data may be referred to as “requested image data”.

When the communication unit 136 of the MFP 15 receives the request information, the determination unit 132 determines whether or not the virus check for the image data (requested image data) requested by the request information has been completed.

The control unit 134 waits until it is determined that the virus check is completed. When the determination unit 132 determines that the virus check has been completed, the control unit 134 transmits the image data determined that the virus check has been completed to the external device 20.

For example, the external device 20 generates a Web screen (World Wide Web) based on the image data determined that the virus check has been completed, and transmits the Web screen (World Wide Web) to the external device 20. When the external device 20 receives the image data, the control unit 210 displays an image based on the image data on the display unit 206. For example, the external device 20 displays a Web screen based on image data by a browser.

As a result, the user can recognize that the external device 20 has received the desired image data. Further, the control unit 210 may store the received image data in the storage unit 204.

FIG. 6 is a diagram for explaining an image based on image data. In the example of FIG. 6, the thumbnail image 2064 is displayed in the display area 206A as an image based on the image data. The pointer 2062 is also displayed in the display area 206A.

The user moves the pointer 2062 with a mouse or the like to move the pointer 2062 to a position where the pointer 2062 is superimposed on the link information 2060. When the pointer 2062 is moved to a position where it overlaps with the link information 2060, the user can specify the thumbnail image 2064 by clicking the mouse. When the thumbnail image 2064 is designated, the control unit 210 reads the image data based on the thumbnail image from the storage unit 204, and displays the image based on the read image data (not particularly shown) in the display area 206A. ..

[Flowchart of image data transmission system 1000]
FIG. 7 is a flowchart of the image data transmission system 1000. The arrow shown by the broken line in FIG. 7 indicates the exchange of information.

FIG. 7 shows the processing between the MFP 15 and the external device 20. First, in step S2, the control unit 134 determines whether or not the transmission designation has been input. The control unit 134 waits until the transmission designation is input (NO in step S2).

When the control unit 134 determines that the transmission designation has been input (YES in step S2), the process proceeds to step S4. In step S4, the determination unit 132 determines whether or not the virus check for the image data designated by the transmission designation has been completed.

If it is determined in step S4 that the virus check is completed (the virus check is completed without detecting the virus) (YES in step S4), the process proceeds to step S6.

In step S6, the control unit 134 of the MFP 15 determines that the virus check has been completed for the requesting external device 20 (that is, the external device specified by the transmission designation) (safe image data). ) Is sent.

On the other hand, if NO is determined in step S4, the process proceeds to step S8. In step S8, the control unit 134 transmits the access information (link) to the storage unit 104 to the requesting external device 20 (that is, the external device designated by the transmission designation) via the communication unit 136. do.

In step S10, the control unit 210 of the external device 20 receives the access information via the communication unit 202. Next, in step S12, the control unit 210 displays the access information (link) on the display unit 206 (see FIG. 5).

Next, in step S14, the control unit 210 determines whether or not the access information has been designated. The control unit 210 waits until the access information is specified (NO in step S14). When the control unit 210 determines that the access information has been designated (YES in step S14), the control unit 210 proceeds to step S16.

In step S16, the control unit 210 transmits the request information for requesting the image data to the MFP 15 based on the access information (to the address of the link indicated by the access information). In step S18, the control unit 134 receives the request information via the communication unit 136.

When the control unit 134 receives the request information, in step S18, the determination unit 132 determines whether or not the virus check for the image data requested by the request information has been completed.

In step S18, it waits until it is determined that the virus check is completed (NO in step S18). When it is determined in step S18 that the virus check has been completed (YES in step S18), the image data determined to have completed the virus check in step S20 is transmitted to the external device 20.

In step S22, the control unit 210 of the external device 20 receives the image data. Next, in step S24, the control unit 210 displays a thumbnail image based on the image data (see FIG. 6).

Therefore, in the image data transmission system 1000 of the present embodiment, it is possible to improve the flexibility in other processing during the execution of the virus check. At the same time, the convenience of the user can be improved. Further, by visually recognizing the displayed access information, the user can recognize in advance that the virus check for the image data specified for transmission has not been completed and that the image data is transmitted to the external device 20. can.

(2) When the access information displayed by the display unit 206 is specified by the user, the external device 20 transmits the request information to the external device 20 based on the access information (step S16). When the MFP 15 receives the request information and determines that the virus check has been completed, the MFP 15 transmits the image data requested by the request information to the external device 20. Therefore, even if the virus check of the image data is not completed, the image data can be requested at the user's desired timing.

(3) Further, the external device 20 displays a thumbnail image as information indicating that the virus check has been completed (see FIG. 6). Therefore, the user can intuitively recognize that the virus check has been completed.

[Second Embodiment]
Next, the second embodiment will be described. In the first embodiment, when it is determined in step S20 of FIG. 7 that the virus check has not been completed, the control unit 134 has been described as waiting until it is determined that the virus check has been completed (step S20). Repeat the process). In the second embodiment, when it is determined in step S20 that the virus check has not been completed, the control unit 134 transmits the first result information indicating the result of the virus check to the external device 20.

The control unit 210 determines whether or not the virus check has been completed by analyzing the first result information. The control unit 210 causes the display unit 206 to display information based on the first result information. When the first result information is information indicating that the virus check has been completed, the control unit 210 displays a thumbnail image as information indicating that the virus check has been completed (see FIG. 6).

On the other hand, when the first result information is the information indicating that the virus check has not been completed, the control unit 210 displays the information indicating that the virus check has not been completed. FIG. 8 is a diagram showing an example of information indicating that the virus check has not been completed. In the example of FIG. 8, the virus-checking character image 2068 "virus-checking" is displayed as information indicating that the virus check has not been completed.

As described above, in the second embodiment, when the virus check is not completed, the display unit 206 of the external device 20 displays the virus "virus check in progress" as information indicating that the virus check is not completed. The checked character image 2068 is displayed. Therefore, it is possible to make the user aware that the virus check is not completed.

Further, the transmission designation of two or more image data may be input to the MFP 15. Hereinafter, the image data transmission system 1000 that executes the processing in such a case will be described. In the following description, a case where transmission designation of the first image data and the second image data (that is, two image data) is input to the MFP as two or more image data will be described.

When the transmission designation of two or more image data is input, the control unit 134 accesses the storage unit 104 when at least one of the two or more image data has not completed the virus check. Information is transmitted (see FIG. 5 and step S8).

When the access information is specified by the user, the external device 20 transmits the request information to the MFP 15. The determination unit 132 determines whether or not the virus check for each of the two or more requested image data requested by the request information has been completed. The determination unit 132 determines whether or not the virus check for each of the two or more requested image data has been completed, and transmits the first result information for each of the two or more requested image data to the external device 20.

FIG. 9 is a diagram illustrating a case where the required image data includes the first requested image data and the second requested image data. In the example of FIG. 9, the first requested image data corresponds to the first image, and the second requested image data corresponds to the second image. In the example of FIG. 9, for the first image, a thumbnail image 2064 is displayed as information indicating that the virus check has been completed. On the other hand, for the second image, the virus-checking character image 2068 is displayed as information indicating that the virus check has not been completed.

As described above, even when there are a plurality of requested image data, the user can be made to recognize the execution status of the virus check for each of the plurality of requested image data.

[Third Embodiment]
Next, the third embodiment will be described. In the third embodiment, a case where a plurality of unit image data are included in one image data will be described. The requested image data is a first image data and a second image data, and the second image data includes a plurality of unit image data.

When the transmission designation of the first image data and the second image data including a plurality of unit image data is input, the control unit 134 has not completed the virus check for at least one of these image data. If this is the case, the access information of the storage unit 104 is transmitted (see FIG. 5 and step S8).

When the access information is specified by the user (for example, the administrator of the image data transmission system), the external device 20 transmits the request information to the MFP 15. The determination unit 132 determines whether or not the virus check for the image data requested by the request information has been completed. Hereinafter, the requested image data will be referred to as a first requested image data and a second requested image data (including a plurality of unit image data).

The determination unit 132 executes a virus check for each of these requested image data, and transmits the first result information for each of these requested image data to the external device 20.

The control unit 210 determines whether or not the virus check has been completed by analyzing the first result information. The control unit 210 causes the display unit 206 to display information based on the first result information.

FIG. 10 is a diagram illustrating a case where the required image data includes a first requested image data and a second requested image data including a plurality of unit image data. In the example of FIG. 10, the first requested image data corresponds to the first image, and the second requested image data corresponds to the second image.

In the example of FIG. 10, for the first image, the virus-checking character image 2068 is displayed as information indicating that the virus check has not been completed. Further, among the second images, the first unit image (page1 unit image) and the second unit image (page2 unit image) are thumbnail images 2064 as information indicating that the virus check has been completed. Is displayed. Further, in the third unit image (the unit image of Page 3) of the third image, the virus check in progress character image 2068 is displayed as information indicating that the virus check has not been completed.

As described above, in the third embodiment, even when one image data includes a plurality of unit image data, the user can be made to recognize the execution status of the virus check for each of the plurality of unit image data. ..

[Fourth Embodiment]
Next, a fourth embodiment will be described. In the fourth embodiment, the mode setting unit 140 (see the broken line in FIG. 4) can set any one of a plurality of types of modes. The plurality of types of modes include a first mode and a second mode.

The first mode is a mode in which, when it is determined that the virus check has not been completed when the transmission designation is input, the virus waits until the virus check is completed. Further, the first mode is a mode in which the MFP 15 transmits the image data for which the virus check is completed to the external device 20 after it is determined that the virus check is completed after the standby.

The second mode is a mode in which the MFP 15 transmits the access information to the external device 20 when it is determined that the virus check has not been completed when the transmission designation is input.

Further, regardless of whether the first mode or the second mode is set, if the virus check when the transmission designation is input is completed, the MFP 15 will perform the image data for which the virus check has been completed. Is transmitted to the external device 20.

Comparing the first mode and the second mode, in the second mode, the request information may be transmitted from the external device 20 when the virus check is not completed, so that there is a risk of virus spreading. It can be said that there are some. On the other hand, in the first mode, since the image data for which the virus check has been completed is transmitted, there is no risk of spreading the virus. Therefore, the security level of the first mode is higher than that of the second mode.

In the fourth embodiment, the user selects a desired mode from the touch panel 1052 and the like from the first mode and the second mode. The mode setting unit 140 sets the selected mode. For example, the mode setting unit 140 stores the mode information indicating the mode to be set in the storage unit 104. The control unit 134 confirms the set mode by reading the mode information stored in the storage unit 104.

FIG. 11 is a flowchart of the MFP 15 of the fourth embodiment. In the example of FIG. 11, the flow of the external device 20 is not shown as shown in FIG.

As shown in FIG. 11, if NO is determined in step S4, the process proceeds to step S30. In step S30, the control unit 134 confirms which of the first mode and the second mode is set.

When NO is determined in step S30, that is, when it is determined that the second mode is set, the control unit 134 executes the process of step S8.

If YES is determined in step S30, that is, if it is determined that the first mode is set, the process proceeds to step S32. In step S32, the determination unit 132 determines whether or not the virus check for the image data designated for transmission by the transmission designation has been completed.

If it is determined in step S32 that the virus check has not been completed (NO in step S32), the system waits until it is determined that the virus check has been completed. After that, when it is determined that the virus check is completed (YES in step S32), the process proceeds to step S34.

In step S34, the control unit 134 of the MFP 15 transmits the image data determined to have completed the virus check to the requesting external device 20 (that is, the external device designated by the transmission designation).

According to the fourth embodiment, the user can select the mode to be set from the second mode and the first mode having a higher security level than the second mode. Therefore, the image data transmission system can execute the image transmission process at a security level according to the environment in which the image data transmission system is installed.

[Fifth Embodiment]
In the fourth embodiment, it has been described that the user selects either the first mode or the second mode. In the fifth embodiment, the MFP 15 determines the type of the external device 20 to which the image data is transmitted. The mode setting unit 140 sets the mode according to the setting unit.

FIG. 12 is a diagram showing an example of the relationship between the type of the external device 20 and the set mode. In FIG. 12, the external device outside the company means an external device outside the company in which the MFP 15 is installed. Further, the in-house external device means an in-house external device of the company in which the MFP 15 is installed.

In general, the external device outside the company may be, for example, an external device installed at a business partner of a company in which the MFP 15 is installed. On the other hand, the in-house external device is an external device installed in the company where the MFP 15 is installed. Therefore, typically, it is preferable to set the security level regarding the transmission of image data higher in the external device outside the company than in the external device in the company.

Therefore, in the example of FIG. 12, the first mode is associated with the external device outside the company. Further, the second mode is associated with the external device in the company.

The control unit 134 identifies the address (for example, IP address or MAC address) of the external device from the input transmission designation. Based on the address, the control unit 134 identifies whether the external device to which the image data is transmitted is an in-house external device or an in-house external device.

The mode setting unit 140 sets a mode according to the type of the external device 20 specified by the control unit. When the control unit 134 specifies that the external device to which the image data is transmitted is an external device outside the company, the mode setting unit 140 sets the first mode. On the other hand, when the control unit 134 specifies that the external device to which the image data is transmitted is an in-house external device, the mode setting unit 140 sets the second mode.

As described above, in the present embodiment, the criterion for setting the mode is whether the external device for transmitting the image data is an external device outside the company or an external device inside the company. Moreover, the standard of the mode setting may be another standard. For example, the mode setting reference may be the owner of the external device. For example, if the owner of the external device is a human being of a business partner, the security level may be increased, that is, the first mode may be set. Further, when the owner of the external device is a friend or the like, the security level may be lowered, that is, the second mode may be set.

According to the present embodiment, the control unit 134 specifies the type of the external device for transmitting the image data, and the mode corresponding to the specified type is set. Therefore, even if the user does not set the mode, the mode is automatically set, so that the convenience of the user can be improved.

[Sixth Embodiment]
Next, the sixth embodiment will be described. In the sixth embodiment, attention is paid to the importance of the image data designated by the transmission designation.

For example, when the image data specified by the transmission designation is encrypted with a password, the importance of the image data is generally high. When the transmission designation for such highly important image data is input and the virus check for the image data is not completed, the image data is determined when the virus check is completed. Is transmitted to the external device 20.

FIG. 13 is a flowchart of the MFP 15 of the present embodiment. If NO is determined in step S4, the process proceeds to step S40. In step S40, the importance determination unit 142 determines whether or not the image data specified by the transmission designation is encrypted with a password or the like.

When it is determined as NO in step S40, that is, when it is determined that the image data is not encrypted (that is, when it is determined that the importance of the image data is low), the control unit 134 controls the step. The process of S8 is executed.

Further, when YES is determined in step S40, that is, when it is determined that the image data is encrypted (that is, when it is determined that the importance of the image data is high), the process proceeds to step S32. ..

According to the present embodiment, the importance determination unit 142 determines the importance of the image data designated by the transmission designation. When it is determined that the virus check has not been completed when the transmission designation is input, the control unit 134 does not transmit the image data until it is determined that the virus check has been completed. After that, the control unit 134 transmits the image data to the external device 20 after it is determined that the virus check is completed.

Therefore, important image data is transmitted to the external device 20 after the virus check is completed. Therefore, in the image data transmission system 1000 of the present embodiment, it is possible to prevent the virus from spreading with respect to the important image data.

[7th Embodiment]
Next, the seventh embodiment will be described. In the seventh embodiment, the MFP 15 cannot access the storage unit 104 only with the access information for the purpose of enhancing security. In the seventh embodiment, the MFP 15 transmits a password for accessing the storage unit 104 to the external device 20 separately from the access information. That is, in the seventh embodiment, two emails, an access information and a password, are transmitted. The password may be generated by any method. For example, the control unit 134 uses a random number to generate a password.

Regarding the transmission order of the access information and the password, the MFP 15 may transmit the access information first and the password later. Further, the MFP 15 may transmit the password first and the access information later. The display unit 206 of the external device 20 displays the transmitted password.

FIG. 14 is a diagram showing an example of the displayed password. In the example of FIG. 14, the password 2084 and the related information 2082 are displayed. The related information 2082 includes, for example, the name of the MFP 15, the name of the storage unit 104 (BOX), and the name of the image data designated for transmission. In the example of FIG. 14, "Product 11" is displayed as the name of the MFP 15, "Box No. 7" is displayed as the name of the storage unit 104, and "Sample1.pdf" is displayed as the name of the image data. Further, "qwertyuio" is displayed as the password 2084.

When the user specifies access information (see FIG. 5) in the external device 20, the external device 20 displays a password request image (not particularly shown) under the control of the MFP 15. The password request image is an image for requesting a password. The password request image includes an area where the password is entered by the user. When the correct password is entered in the area by the user, access to the storage unit 104 is permitted, and for example, the process from step S18 in FIG. 7 is executed.

According to this embodiment, the password is transmitted together with the access information. Therefore, the security of access to the storage unit 104 can be improved.

[Eighth Embodiment]
Next, the eighth embodiment will be described. In the first embodiment, as shown in FIG. 7, when the transmission designation is input and the determination unit 132 determines that the virus check is completed, the image data is transmitted to the external device 20. It has been described that when the determination unit 132 determines that the virus check has not been completed, the access information is transmitted to the external device 20.

FIG. 15 is a diagram showing a flowchart of the eighth embodiment. As shown in FIG. 15, when it is determined in step S4 that the virus check has not been completed, that is, when it is determined to be NO in step S4, the control unit 134 stands by. After that, when it is determined that the virus check is completed, the access information is transmitted to the external device 20 in step S8.

As described above, in the present embodiment, when the transmission designation is input (YES in step S2) and it is determined that the virus check is not completed (NO in step S4), the virus check is completed. After the determination (YES in step S4), the control unit 134 transmits the access information to the external device 20.

Thereby, in the image data transmission system 1000 of the present embodiment, it is possible to improve the flexibility in other processing during the execution of the virus check. At the same time, the convenience of the user can be improved. Further, the user can recognize that the virus check for the image data designated for transmission has been completed by visually recognizing the displayed access information. In addition, it is not necessary to provide means for preventing access during virus check (access restriction from access information, etc.).

[9th Embodiment]
Next, the ninth embodiment will be described. The image data transmission system of the ninth embodiment uses a job list. First, the job list will be described.

FIG. 16 is an example of the job list of the present embodiment. The job list is stored in, for example, the storage unit 104. In the job list of FIG. 16, a job ID is assigned to the job, and the image ID of the image used in the job is associated with the detailed information of the job. In the following, a job ID is assigned after the job for the name of the job. For example, a job having a job ID of 2 is referred to as "job 2". As for the name of the image data, an image data ID is added after the image data. For example, a job whose image data ID is G2 is referred to as "image data G2".

In the example of FIG. 16, the job 1 (first job) is a transmission job, the target data is the image data G1, and the destination address is associated with the detailed information. In the example of FIG. 16, a “print job” is registered as job 2 (second job), the target data is image data G2, and mode information is associated with detailed information. The mode information indicates the mode of the printing process, for example, whether it is color printing or monochrome printing, whether it is double-sided printing or single-sided printing, and how many sheets are printed. Information. Further, in the example of FIG. 16, N jobs are registered.

In the present embodiment, the image data used in the "job that may spread the virus by being executed" is subject to the virus check by the virus check unit 130. The "job that may spread a virus by being executed" is, for example, a transmission job.

In the present embodiment, the virus check unit 130 executes a virus check on the image data to be transmitted in the job list transmission job in ascending order from the one with the smallest job number.

Further, in the present embodiment, the virus check is not executed for the image data used in the print job in the reserved job list. As a result, the frequency of virus check execution can be reduced. As a modification, the virus check unit 130 may execute a virus check on the image data used in the print job.

FIG. 17 is a flowchart of the MFP 15 of the ninth embodiment. FIG. 17 is a flowchart in which the idea of the job list is applied to the flowchart of the MFP of FIG.

If NO is determined in step S4, the process proceeds to step S50. In step S50, the control unit 134 registers the transmission job based on the transmission designation in step S2 in the job list.

Next, in step S52, the control unit 134 determines whether or not one or more jobs remain in the job list. When the control unit 134 determines that no job remains in the job list (No in step S52), the process ends. If the control unit 134 determines that the job remains in the job list (Yes in step S52), the process proceeds to step S54.

In step S54, the control unit 134 reads the first job from the reserved job list. In the example of FIG. 17, the job No. Read the job with the smallest (job number) (that is, job 1). In the example of FIG. 17, the transmission job of job 1 is read out.

Next, in step S56, the determination unit 132 determines whether or not the virus check of the image data designated for transmission, that is, the image data transmitted by the read transmission job has been completed. When it is determined by the determination unit 132 that the virus check has not been completed (NO in step S56), the process proceeds to step S58.

In step S58, the control unit 134 transmits the access information to the storage unit 104 to the requesting external device 20 (that is, the external device designated by the transmission designation) via the communication unit 136. The process of step S58 is the same as the process of step S8 of FIG.

When the process of step S58 is completed, the process proceeds to step S60. In step S60, the control unit 134 deletes the image data transmission job determined to have completed the virus check in step S56. Then, the process returns to step S52.

Further, even if NO is determined in step S56, the process returns to step S52. Further, the image data transmission job for which the virus check is determined not to be completed in step S56 is not deleted but remains.

Further, although not shown in FIG. 16, when a "job that does not cause virus spread" is read in reading a job from the reserved job list in step S54, processing based on the job is read. Is executed. The "job that does not cause virus spread" is, for example, a print job. The print job is a job printed by the MFP 10 itself, not a process of transmitting data to another external device. Therefore, even when the print job is executed, the virus does not spread. Therefore, a job (such as a print job) that does not cause virus spread is executed when it is read from the job list.

In this way, the reserved job list is an image data ID (data identification) for identifying each of one or more image data for which the virus check has not been completed for the image data specified by the input transmission designation. Information) is memorized.

Further, the control unit 134 determines whether or not the virus check has been completed for the image data designated for transmission (step S56). The control unit 134 provides access information for the external device 20 to access the image data every time it is determined that the virus check of the image data designated for transmission is completed (every time it is determined that Yes in step S56). Is transmitted to the external device 20. Therefore, for example, even if a plurality of jobs are input to the MFP 15, the plurality of jobs can be flexibly processed by using the job list.

Next, a modified example of the ninth embodiment will be described. The processes of steps S52 to S58 described with reference to FIG. 17 may be applied to the processes of the MFP 15 of FIG. 7. FIG. 18 is a flowchart in which the processes of steps S52 to S58 are applied to the processes of the MFP 15 of FIG. Even the MFP 15 that executes the process in such a flowchart has the same effect as that of the ninth embodiment.

Next, another modification of the ninth embodiment will be described. The process of step S58 may be a process of transmitting image data (image data determined in step S56 that the virus check process is completed) instead of the process of transmitting access information. With such a configuration, the image data can be directly transmitted to the external device 20 for the transmission designation in the job list, so that the convenience of the user can be improved.

[10th Embodiment]
Next, the tenth embodiment will be described. FIG. 19 is a flowchart of the tenth embodiment. As shown in FIG. 19, in the tenth embodiment, when the determination unit 132 determines that the virus check has not been completed (NO in step S4), the process proceeds to step S70.

In step S70, the control unit 134 (process execution unit) executes the image data conversion process in order to prevent the virus of the image data designated for transmission from spreading. The image data is configured in a predetermined format (format). In the present embodiment, the predetermined format is PDF (Portable Document Format). The predetermined format may be any of JPEG (Joint Photographic Experts Group), XPS (XML Paper Specification), TIFF (Tag Image File Format), PNG (Portable Network Graphics), and BMP (bitmap). ..

The conversion process is a process of converting the image data from PDF, which is a predetermined format, into either raster data or RAW data. Raster data is data composed of cells (pixels) arranged in a grid pattern of rows and columns. RAW data is the original data (data before being converted to PDF). When the process of step S70 is completed, the process proceeds to step S72.

In step S72, the control unit 134 (processing execution unit) returns the image data converted in step S70 to the original format (PDF). Next, in step S74, the control unit 134 transmits the image data returned to the original format in step S72 to the external device 20 (external device designated by the transmission designation).

In the present embodiment, when the transmission designation is input and the virus check is not completed, the control unit 134 executes the conversion process and transmits the image data after the change process to the external device 20. .. This conversion process is the process of step S70 and step S72 of FIG. That is, this conversion process is a process of converting the image data into either raster data or RAW data, and returning the converted image data to the format of the image data before the conversion. By this conversion process, even if the original PDF image data is infected with a virus, the virus can be eliminated. Therefore, when the transmission designation is input, the MFP 15 can transmit secure image data to the external device 20 even when the virus check is not completed. Further, since the MFP 15 does not have to wait for the completion of the virus check, the secure image data can be quickly transmitted.

As a further modification of the ninth embodiment and the tenth embodiment, the MFP 15 may execute both the conversion process of the ninth embodiment and the deletion process of the tenth embodiment. That is, the MFP 15 may execute at least one of the conversion process and the delete process.

[11th Embodiment]
Next, the eleventh embodiment will be described. FIG. 20 is a flowchart of the eleventh embodiment. As shown in FIG. 20, in the eleventh embodiment, if the determination unit 132 determines that the virus check has not been completed (NO in step S4), the process proceeds to step S80.

In step S80, the control unit 134 (process execution unit) executes a process of deleting a part of the image data in order to prevent the virus of the image data designated for transmission from spreading. A part of the image data is additional data added to the main body of the image data. The additional data includes the metadata of the image data and at least one of the alpha channels of the image data. The metadata of the image data is, for example, additional data about the image data itself accompanied by the image data. Further, the alpha channel of the image data is, for example, auxiliary data different from the color expression data for each pixel of the image data. The auxiliary data is, for example, data expressing the opacity of a pixel.

Next, in step S82, the control unit 134 transmits the image data from which the additional data has been deleted to the requesting external device 20.

In the present embodiment, when the transmission designation is input and the virus check is not completed, the control unit 134 executes the deletion process and transmits the image data after the deletion process to the external device 20. .. This deletion process is the process of step S80 in FIG. That is, this deletion process is a process of deleting additional data of image data (metadata of image data and at least one of alpha channels of image data). By this deletion process, even if the additional data of the image data is infected with the virus, the virus can be eliminated. Therefore, when the transmission designation is input, the MFP 15 can transmit secure (secure) image data to the external device 20 even when the virus check is not completed. Further, since the MFP 15 does not have to wait for the completion of the virus check, the secure image data can be quickly transmitted.

[12th Embodiment]
Next, a twelfth embodiment will be described. The MFP 15 of the twelfth embodiment executes the process based on the output type of the image data of the external device 20. FIG. 21 is a diagram showing the correspondence between the output type of the image data of the external device 20 designated by the transmission designation and whether or not the output of the image data for which the virus check has not been completed is prohibited. The data based on FIG. 21 is stored in the storage unit 104 in advance.

In the example of FIG. 21, when the output type of the external device 20 is transfer (transfer to an external device different from this external device 20), the image data for which virus check has not been completed is transmitted to the external device 20. Is prohibited. When image data for which virus check has not been completed is infected with a virus, the virus may spread when the image data is transferred. Therefore, in the example of FIG. 21, when the output type of the external device 20 is transfer, transmission of image data for which virus check has not been completed to the external device 20 is prohibited.

Further, in the example of FIG. 21, when the output type of the external device 20 is printing, the image data for which the virus check has not been completed can be transmitted (allowed) to the external device 20. This case is, for example, a case where the external device 20 is an MFP different from the MFP 15. When the external device 20 (an MFP different from the MFP 15) prints based on the image data, if the image data is infected with a virus, the external device 20 itself may be infected with the virus. However, since it does not send information to other devices, it is unlikely (or unlikely) to spread the virus. Therefore, when the output type of the external device 20 is printing, the image data for which the virus check has not been completed can be transmitted to the external device 20.

Further, in the example of FIG. 21, when the output type of the external device 20 is storage (output) in the BOX (storage unit), transmission of image data for which virus check has not been completed to the external device 20 is prohibited. .. When image data for which virus check has not been completed is stored in the BOX, the image data may be transmitted to another device. If the image data for which virus check has not been completed is infected with a virus, the other device may be infected with the virus. Therefore, in the example of FIG. 21, when the output type of the external device 20 is transfer, transmission of image data for which virus check has not been completed to the external device 20 is prohibited.

As described above, in the example of FIG. 21, the output type related to transfer and the output type related to BOX storage are referred to as "virus spread output type" because they are types in which a virus may spread. The spread of a virus means, for example, the spread of a virus to an electronic device connected to a network 30 (see FIG. 1).

FIG. 22 is a flowchart of the MFP 15 of the twelfth embodiment. If NO is determined in step S4, the process proceeds to step S90.

In step S90, the control unit 134 (confirmation unit) confirms the output type of the external device 20 designated by the input transmission designation. This confirmation method includes a first confirmation method and a second confirmation method.

The first confirmation method is, for example, a method in which the control unit 134 confirms the output type of the external device 20 by analyzing the input transmission designation. Further, in the second confirmation method, the control unit 134 transmits confirmation information to the external device 20. This confirmation information is information for confirming the output type to the external device 20. Upon receiving the confirmation information, the external device 20 transmits the confirmation result information to the MFP 15. This confirmation result information is information indicating whether or not the output type of the external device 20 is a virus spread output type. By analyzing this confirmation result information, the MFP 15 confirms whether or not the output type of the external device 20 is the virus spread output type.

Next, in step S94, the control unit 134 determines whether or not the output type of the external device is a virus spread output type (transfer, storage in BOX, etc.). The control unit 134 executes this determination process based on the confirmation result in step S92.

If it is determined to be Yes in step S92, that is, if the output type of the external device 20 is the virus spread output type, the process returns to step S4. After that, the process of NO in step S4 → YES in step S92 → NO in step S4 ... Is repeated until it is determined to be YES in step S4 (until it is determined that the virus check is completed). .. After that, if YES is determined in step S4 (when it is determined that the virus check is completed), the control unit 134 transmits image data in step S6. That is, the external device 20 outputs the image data (image data transmitted in step S6) determined to have completed the virus check.

If it is determined to be Yes in step S92, that is, if the output type of the external device 20 is not the virus spread output type, the process proceeds to step S6. In step S6, the control unit 134 transmits image data. That is, the external device 20 outputs the image data (image data transmitted in step S6) determined to have completed the virus check.

According to the present embodiment, when it is confirmed that the output type of the external device 20 is not the virus diffusion output type (YES in step S92), the image data determined that the virus check has not been completed is used as the image data of the external device 20. Send to. That is, if the output type has no possibility of spreading the virus, even the image data for which the virus check has not been completed is transmitted to the external device 20. Therefore, the external device 20 can output the image data safely and quickly (the printing process based on the image data can be executed).

Further, when the output type of the external device 20 is confirmed to be the virus spread output type (NO in step S92), the virus check is completed for the image data for which the virus check is determined not to be completed. Waits until, and when it is determined that the virus check is completed, the image data is transmitted to the external device 20. Therefore, the external device 20 can safely output the image data (the transfer process or the BOX storage process based on the image data can be safely executed).

Further, in the above-described embodiment, various processes when the virus check is not completed when the transmission designation is input have been described. Therefore, the MFP 15 in the above-described embodiment can improve flexibility in other processes during virus checking.

[Modification example]
The present invention is not limited to the above examples, and various modifications and applications are possible. Hereinafter, modifications applicable to the present invention will be described.

(1) For example, as shown in step S12 and step S14 of FIG. 7, the transmission trigger for transmitting the request information to the MFP 15 has been described as the trigger for the access information to be specified by the user. However, the transmission trigger may be another trigger. For example, the transmission trigger may be when the virus check completion information is received. The virus check completion information is information indicating that the virus check for the image data specified by the input transmission designation has been completed.

In such a configuration, when the external device 20 receives the access information from the MFP 15 in step S10, the external device 20 waits until the access completion information from the MFP 15 is received. After that, when the external device 20 receives the access completion information from the MFP 15, the MFP 15 transmits the request information. Further, in the case of such a configuration, it is not necessary to display the access information (it is not necessary to execute the process of step S12).

According to such a configuration, the external device 20 automatically requests the image data from the MFP 15 without having the user specify the access information. Therefore, the convenience of the user can be improved.

(2) The external device 20 may be another MFP different from the MFP 15. That is, the transmission system includes the MFP 15 and other MFPs. In such a configuration, for example, the access information received in the process of step S10 of FIG. 7 is stored in the storage unit of the other MFP. After that, when the other MFP receives the access completion information from the MFP 15, the other MFP requests the image data based on the access information. According to such a configuration, it is possible to carry out image data communication between MFPs while applying the idea of the present embodiment.

(3) In FIG. 7, in step S18, when it is determined once that the virus check is not completed (NO in step S18), it waits until it is determined that the virus check is completed (YES in step S18). I explained that it would be done. However, when it is determined once that the virus check has not been completed (NO in step S18), the MFP 15 transmits the virus check incomplete information to the external device 20, and the external device 20 "virus check has not been completed". You may display the text image "It's done".

(4) An example in which the data transmission device 10 of the present embodiment is applied to the MFP 15 has been described. However, the data transmission device 10 may be applied to other devices. The data transmission device 10 may be applied to, for example, an information processing device (PC, smartphone, tablet) or the like.

It should be considered that each embodiment disclosed this time is exemplary in all respects and is not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims. Further, the inventions described in the embodiments and the modifications thereof are intended to be carried out alone or in combination as much as possible.
