Specifically, the authentication unit 128 stores, for example, the user ID and password input by the user via the input unit 111 in the storage unit 118 (or the storage unit 126), and the user information for granting the use permission. If it matches, the user is allowed to log in to the MFP 1a. The authentication unit 128 is realized by, for example, a program executed by the CPU 501 shown in FIG.

The document detection unit 121, the warning determination unit 122, the reading processing unit 123, the warning setting unit 124, the inter-device communication unit 125, the storage unit 126, the external communication unit 127, and the authentication unit 128 of the main body 12a shown in FIG. 9 have functions. Is conceptually shown, and is not limited to such a configuration. For example, a plurality of functional units shown as independent functional units in the main body 12a shown in FIG. 9 may be configured as one functional unit. On the other hand, the function of one functional unit in the main body 12a shown in FIG. 9 may be divided into a plurality of functions and configured as a plurality of functional units.

Further, of the functional parts of the main body 12a, at least a part of the functional parts realized by software (program) may be realized by a hardware circuit such as FPGA or ASIC.

FIG. 10 is a flowchart showing an example of a warning display operation in the MFP according to the first modification of the first embodiment. FIG. 11 is a diagram illustrating an operation from setting a document to displaying a warning screen. The warning display operation in the MFP 1a according to this modification will be described with reference to FIGS. 10 and 11. It is assumed that the setting screen 1010 shown in FIG. 5 described above is set in advance to display a warning display screen when a remote job for reading a document from a remote location is received.

<< Step S31 >>
The user sets the original on the original glass of the MFP 1a in order to perform an operation involving a reading operation (for example, a scanning operation). Then, the process proceeds to step S32.

<< Step S32 >>
The document detection unit 121 confirms (determines) whether or not the document is placed on the document glass. When the document is placed on the document glass (step S32: Yes), the process proceeds to step S33, and when the document is not placed (step S32: No), the document detection unit 121 continues the confirmation (determination) operation.

<< Step S33 >>
The user performs a login operation (for example, an operation of inputting a user ID and a password) to the input unit 111. For example, as shown in FIG. 11, the user inputs a user ID and a password via the login screen 1030 displayed on the display unit 117. Then, the process proceeds to step S34.

<< Step S34 >>
The authentication unit 128 authenticates the user who intends to use the MFP 1a. Specifically, the authentication unit 128 stores, for example, the user ID and password input by the user via the input unit 111 in the storage unit 118 (or the storage unit 126), and the user information for granting the use permission. If it matches, the user is allowed to log in to the MFP 1a. If login is permitted (when login is OK) (step S34: Yes), the process proceeds to step S35, and if login is not permitted (step S34: No), the process returns to step S33, and the user re-logs in.

<< Step S35 >>
When the manuscript is placed on the manuscript glass by the user and login is permitted, the warning determination unit 122 makes a warning determination. Specifically, when login is permitted, the warning determination unit 122 has received a remote job (for example, a remote scan job, etc.) including a read processing job from the remote (external) by the external communication unit 127. Judge whether or not. When the remote job is received (step S35: Yes), the process proceeds to step S36, and when the remote job is not received (step S35: No), the process proceeds to step S40.

<< Step S36 >>
When a remote job (for example, a remote scan job) including a read processing job is received by the external communication unit 127 from the remote (external), the warning determination unit 122 displays a warning (for example, the warning display shown in FIG. 11). Screen 1022 (an example of information indicating a warning) is displayed on the display unit 117). Then, the process proceeds to step S37.

<< Steps S37-S40 >>
The operation of steps S37 to S40 is the same as the operation of steps S15 to S18 shown in FIG. 8 above.

The warning display operation of the MFP 1a is performed by the flow shown in the above steps S31 to S40.

That is, until the user logs in, the received remote job is not executed and waits. After logging in, if the user determines that the remote job is appropriate, the remote job is executed, and if it is determined that the remote job is invalid, such as when the source cannot be identified, the remote job is deleted. As a result, it is possible to suppress the reading of an illegal document by a remote job received from a remote (external).

(Modification 2)
The MFP according to the modified example 2 will be described focusing on the differences from the operation of the MFP 1a according to the above-mentioned modified example 1. The hardware configuration of the MFP according to this modification is the same as the hardware configuration of the MFP 1 according to the first embodiment described above. Further, since the functional block configuration of the MFP according to the present modification is the same as the functional block configuration of the MFP1a according to the above-mentioned modification 1, the MFP according to the present modification will also be referred to as "MFP1a" for convenience. It shall be.

<MFP warning display operation>
FIG. 12 is a flowchart showing an example of a warning display operation in the MFP according to the second modification of the first embodiment. The warning display operation in the MFP 1a according to this modification will be described with reference to FIG. 12. It is assumed that the setting screen 1010 shown in FIG. 5 described above is set in advance to display a warning display screen when a remote job for reading a document from a remote location is received.

<< Step S51 >>
A user (regular user), for example, commands a remote job (for example, remote) from his / her own PC or tablet (for example, tablet 4 shown in FIG. 2) (an example of a mobile terminal) to an operation including a read operation for the MFP 1a. Publish a scan job, etc.). The remote job is received by the external communication unit 127 of the MFP 1a via the access point 5 or the network 2. Then, the process proceeds to step S52.

<< Step S52 >>
When the remote job is received by the external communication unit 127, the authentication unit 128 issues an ID for executing the remote job. The ID issued by the authentication unit 128 is transmitted to the user's PC or tablet via the network 2 or the access point 5. Then, the process proceeds to step S53.

<< Step S53 >>
The user sets the original on the original glass of the MFP 1a in order to perform an operation involving a reading operation (for example, a scanning operation). Then, the process proceeds to step S54.

<< Step S54 >>
The document detection unit 121 confirms (determines) whether or not the document is placed on the document glass. When the document is placed on the document glass (step S54: Yes), the process proceeds to step S55, and when the document is not placed (step S54: No), the document detection unit 121 continues the confirmation (determination) operation.

<< Step S55 >>
The user performs a login operation to the input unit 111 by using the ID issued by the authentication unit 128. Then, the process proceeds to step S56.

<< Step S56 >>
The authentication unit 128 authenticates the user who intends to use the MFP 1a. Specifically, the authentication unit 128 determines, for example, whether or not at least the information of the issued ID among the information input by the user via the input unit 111 matches, and if they match, the user is notified. Allow login to MFP1a. If login is permitted (when login is OK) (step S56: Yes), the process proceeds to step S57, and if login is not permitted (step S56: No), the process returns to step S55, and the user re-logs in.

<< Step S57 >>
When the manuscript is placed on the manuscript glass by the user and login is permitted, the warning determination unit 122 makes a warning determination. Specifically, the warning determination unit 122 includes a job for reading processing by the external communication unit 127 from a remote (external) (including a PC or tablet or a PC that has issued a mote job by the user) when login is permitted. Determine if a remote job (eg, remote scan job, etc.) has been received. When the remote job is received (step S57: Yes), the process proceeds to step S58, and when the remote job is not received (step S57: No), the process proceeds to step S62. However, in the case of FIG. 12, since the remote job is issued by the user at least in step S51, the remote job is received by the warning determination unit 122 in step S57.

<< Step S58 >>
The warning determination unit 122 receives a remote job (for example, a remote scan job, etc.) including a read processing job by the external communication unit 127 from a remote (external) (including a PC or tablet or tablet that has issued a remote job by the user). If so, a warning is displayed. Specifically, the warning determination unit 122 displays, for example, on the warning display screen (an example of information indicating a warning) displayed on the display unit 117, the issuer of the remote job (whether it is the user's own remote job or another person's remote job). It may be to display the information indicating (is it?). Further, in this case, the display control unit 116 transmits the information on the warning display screen to the user's PC or the like or a tablet (an example of a mobile terminal) via the network 2 or the access point 5, and the warning is displayed on the screen. The display screen may be displayed. Then, the process proceeds to step S59.

<< Steps S59 to S61 >>
The operation of steps S59 to S61 is the same as the operation of steps S37 to S39 shown in FIG. 10 above. Then, the process proceeds to step S62.

<< Step S62 >>
After that, the user performs an execution operation for his / her remote job accompanied by an operation of reading the document placed on the original glass (for example, a selection operation of not deleting the remote job on the warning display screen displayed in the same manner as in step S58). It should be. At the time of step S57, it is unknown whether the remote job of the user or the remote job other than the user is received first as the remote job. Therefore, for example, when the user's remote job is received first, the process for the remote job is operated, and then the process for the remote job other than the user (for example, the operation for deleting the remote job on the warning display screen) is performed. It should be done. Then, the warning display operation of the MFP 1 ends.

The warning display operation of the MFP 1a is performed by the flow shown in the above steps S51 to S62.

As described above, the MFP1a according to this modification is a remote including a reading operation from a remote (external) (including a PC or tablet or a PC that has issued a mote job by the user) when the original is placed on the original glass. When a job (remote scan job, remote fax job, etc.) is received, a warning display screen is displayed on the display unit 117 when the user logs in, and a warning is given to the user. That is, until the user logs in, the received remote job is not executed and waits. After logging in, if the user determines that the remote job is appropriate, the remote job is executed, and if it is determined that the remote job is invalid, such as when the source cannot be identified, the remote job is deleted. As a result, it is possible to suppress the reading of an illegal document by a remote job received from a remote (external).

[Second Embodiment]
The MFP according to the second embodiment will be described focusing on the differences from the MFP 1 according to the first embodiment. In the first embodiment, when the original is placed on the original glass of the MFP 1, the warning display screen is displayed when the remote job including the reading operation is received from the remote. However, not all remote jobs received remotely are invalid remote jobs, and of course, they may be proper remote jobs. In the present embodiment, an operation of determining whether or not the remote job received from the remote is a job requiring a warning is performed. The hardware configuration of the MFP according to the present embodiment is the same as the hardware configuration of the MFP 1 according to the first embodiment described above.

(Configuration and operation of functional blocks of MFP)
FIG. 13 is a diagram showing an example of the configuration of the functional block of the MFP according to the second embodiment. FIG. 14 is a diagram illustrating an operation of periodically transmitting a remote job from the outside. FIG. 15 is a diagram illustrating that the issuer of the remote job is a reliable terminal. FIG. 16 is a diagram showing an example of a warning setting screen for setting a warning operation when a remote job is received. The configuration and operation of the functional block of the MFP 1b according to the present embodiment will be described with reference to FIGS. 13 to 16.

As shown in FIG. 13, the MFP 1b includes, for example, an operation unit 11 that accepts user operations, and a main body 12b that realizes various image forming functions such as a copy function, a scanner function, a fax function, and a printer function. .. The operation of the operation unit 11 of the MFP 1b according to the present embodiment is the same as the operation of the operation unit 11 of the MFP 1 according to the first embodiment described above.

As shown in FIG. 13, the main body 12b of the MFP 1b includes a document detection unit 121 (detection unit), a warning determination unit 122, a reading processing unit 123, a warning setting unit 124, an inter-device communication unit 125, and a storage unit. It has 126, an external communication unit 127 (acquisition unit), and a terminal position determination unit 129. The operations of the document detection unit 121, the reading processing unit 123, the inter-device communication unit 125, the storage unit 126, and the external communication unit 127 are as described in the first embodiment described above.

As shown in FIG. 15, the terminal position determination unit 129 receives the position information of the terminal that issues (transmits) the remote job via the external communication unit 127, and determines the position of the terminal based on the position information. It is a functional part to do. The location information may be added to and transmitted to a remote job issued from the terminal, for example. The terminal position determination unit 129 is realized by, for example, a program executed by the CPU 501 shown in FIG.

Does the warning determination unit 122 display a warning when a remote job is received by the external communication unit 127 from the remote (external) instead of the job generated by the operation on the operation panel 525 (operation for the input unit 111)? It is a functional unit that determines whether or not it is. Specifically, the warning determination unit 122 determines, for example, whether or not the received remote job is periodically issued from the remote, whether or not the remote job is received by short-range wireless communication, and. , Whether or not the issuer (sender) of the remote job is a reliable issuer is determined. That is, in any of the determinations, it is determined whether or not the issuer (sender) who issued the remote job is a reliable issuer.

Here, in order to determine whether or not the received remote job is periodically issued from the remote, for example, the warning determination unit 122 refers to the history of the received remote job and as shown in FIG. It may be determined based on whether the remote scan job is periodically received or the address book information stored in the storage unit 126 (or the storage unit 118) is acquired periodically. In this case, the warning determination unit 122 determines that the warning is displayed when it is determined that the received remote job is periodically issued from the remote. If the device information (paper remaining amount, toner remaining amount, etc.) of the MFP1b is periodically acquired remotely from the warning determination unit 122, the legitimate terminal acquires the information for maintenance or the like. It may be determined that the warning is not displayed.

Further, in order to determine whether or not the remote job has been received by short-range wireless communication, for example, the warning determination unit 122 may be subjected to Wifi-Direct (registered trademark) by the external communication unit 127 as shown in FIG. ), Or when a remote job is received based on a wireless communication standard such as Bluetooth (registered trademark), it may be determined that the remote job has been received by short-range wireless communication. Further, when the warning determination unit 122 compares the position of the terminal determined by the terminal position determination unit 129 with the position of the MFP 1b and determines that they are close to each other, the remote job is said to have been received by short-range wireless communication. It may be determined. In this case, when the warning determination unit 122 determines that the remote job has been received by short-range wireless communication, the terminal that issued the remote job is a reliable terminal (a reliable user) that exists in a short distance of the MFP1b. It is determined that the terminal is used), and it is determined that the warning is not displayed.

Further, in order to determine whether or not the issuer of the remote job is a reliable issuer, for example, the warning determination unit 122 determines that the received remote job has user authentication, as shown in FIG. It suffices to determine whether or not an authentication token to be indicated, a client certificate certifying that the terminal is a legitimate terminal, or the like is attached. Further, as will be described later, the warning determination unit 122 may determine whether or not the job is a remote job from a terminal set (registered) as a reliable terminal by the warning setting unit 124. In this case, the warning determination unit 122 is used when an authentication token, a client certificate, or the like is attached to the received remote job, or from a terminal set (registered) as a reliable terminal by the warning setting unit 124. In the case of the remote job, it is determined that the terminal that issued the remote job is a reliable terminal (a terminal used by a reliable user), and it is determined that the warning is not displayed.

Then, for example, when the warning determination unit 122 determines that the received remote job is periodically issued from the remote, the warning display screen 1023 (an example of information indicating a warning) shown in FIG. 14 is displayed on the display unit 117. To display. The warning display screen 1023 shown in FIG. 14 is a screen that displays a warning for the received remote scan job, displays that the remote scan job has been received, and determines whether or not to delete (block) the remote scan job. This is the screen for confirmation.

The warning determination unit 122 is realized by, for example, a program executed by the CPU 501 shown in FIG.

It should be noted that the determination mode for determining whether or not to perform the warning display performed by the warning determination unit 122 shown above is an example, and it is not necessary to make a determination for all of the above-mentioned determination modes, at least. Any determination mode may be adopted.

The warning setting unit 124 is a functional unit that sets a warning display according to an operation input from the user to the input unit 111. Specifically, the warning setting unit 124 causes the display unit 117 to display the setting screen 1011 shown in FIG. 16, for example. The setting screen 1011 shown in FIG. 16 displays a warning display screen when a remote job for reading the original is received in a state where the original (paper) is set (that is, a warning). This is a screen for setting (whether or not to make the determination unit 122 determine the warning display). The warning setting unit 124 displays the setting screen 1012 as shown in FIG. 16 when the "detailed setting" button is pressed on the setting screen 1011. The setting screen 1012 shown in FIG. 16 sets whether or not to display a warning for a remote job received from a terminal at a short distance, and a terminal (node) that does not display a warning even if the remote job is received. This is the screen for setting (registration). The detailed settings that can be set on the setting screen 1012 are not limited to the above-mentioned contents, and other settings (for example, settings for a reliable short-range wireless communication standard, etc.) can be made. good.

The document detection unit 121, the warning determination unit 122, the reading processing unit 123, the warning setting unit 124, the inter-device communication unit 125, the storage unit 126, the external communication unit 127, and the terminal position determination unit 129 of the main body 12b shown in FIG. 13 , The function is conceptually shown, and is not limited to such a configuration. For example, a plurality of functional units shown as independent functional units in the main body 12b shown in FIG. 13 may be configured as one functional unit. On the other hand, the function of one functional unit in the main body 12b shown in FIG. 13 may be divided into a plurality of functions and configured as a plurality of functional units.

Further, of the functional parts of the main body 12b, at least a part of the functional parts realized by software (program) may be realized by a hardware circuit such as FPGA or ASIC.

Specifically, the authentication unit 128 stores, for example, the user ID and password input by the user via the input unit 111 in the storage unit 118 (or the storage unit 126), and the user information for granting the use permission. If it matches, the user is allowed to log in to the MFP 1c. If login is permitted (when login is OK) (step S94: Yes), the process proceeds to step S95, and if login is not permitted (step S94: No), the process returns to step S93, and the user re-logs in.

<< Step S95 >>
When the manuscript is placed on the manuscript glass by the user and login is permitted, the warning determination unit 122 is a remote job (for example, a remote scan job or the like) including a job of reading processing from the remote (external) by the external communication unit 127. Is received or not. When the remote job is received (step S95: Yes), the process proceeds to step S96, and when the remote job is not received (step S95: No), the process proceeds to step S102.

<< Step S96 >>
When the remote job is received by the external communication unit 127, the warning determination unit 122 determines whether or not to display the warning. Specifically, the warning determination unit 122 determines, for example, whether or not the received remote job is periodically issued from the remote, whether or not the remote job is received by short-range wireless communication, and. , It is determined whether or not the issuer of the remote job is a reliable issuer, and whether or not a warning is displayed is determined based on these results. Then, the process proceeds to step S97.

<< Step S97 >>
As a result of the determination by the warning determination unit 122, if a warning should be displayed for the received remote job (step S97: Yes), the process proceeds to step S98, and if the warning should not be displayed (step S97: No), step S101. Move to.

<< Step S98 >>
The warning determination unit 122 displays a warning (for example, the warning display screen 1023 shown in FIG. 14 above) for a remote job (for example, a remote scan job) including a job for reading processing from the remote (external) by the external communication unit 127. Display on the display unit 117). Then, the process proceeds to step S99.

<< Step S99 >>
On the warning display screen displayed on the display unit 117, the user determines whether or not the remote job received by the external communication unit 127 is an appropriate job. When the user determines that the remote job is an invalid job and the operation for deleting the job is selected on the warning display screen (step S99: Yes), the process proceeds to step S100. On the other hand, when the user determines that the remote job is an appropriate job and an operation for not deleting the job is selected on the warning display screen (step S99: No), the process proceeds to step S101.

<< Step S100 >>
The warning determination unit 122 deletes the remote job received by the external communication unit 127 as an invalid job. Then, the process proceeds to step S102.

<< Step S101 >>
The warning determination unit 122 causes the engine unit 507 to execute the job including the read operation (scan operation), assuming that the remote job received by the external communication unit 127 is an appropriate job. Then, the process proceeds to step S102.

<< Step S102 >>
After that, the user may perform an execution operation for his / her own job accompanied by a reading operation of the document placed on the document glass. Then, the warning display operation of the MFP 1c ends.

The warning display operation of the MFP 1b is performed by the flow shown in the above steps S91 to S102.

As described above, when the MFP1c according to the present embodiment receives a remote job (remote scan job, etc.) including a reading operation from a remote (external) when the original is placed on the original glass, the user At the time of logging in, it is determined whether or not to display a warning for the remote job, and if it is determined that a warning should be displayed, a warning display screen shall be displayed on the display unit 117 to the user. It is supposed to indicate a warning. For example, the warning determination unit 122 of the MFP 1c determines whether or not the received remote job is periodically issued from the remote, whether or not the remote job is received by short-range wireless communication, and whether or not the remote job is received. It is determined whether or not the issuer of the job is a reliable issuer, and whether or not a warning is displayed is determined based on these results. As a result, it is possible to suppress the reading of an illegal document by a remote job received from a remote (external). Further, when it is determined that it is not necessary to display the warning instead of displaying the warning for all the received remote jobs, the remote job is executed without displaying the warning, which improves the convenience of the MFP1c. be able to.

When the user logs in to the MFP 1c, the ID issued to the (regular) user's remote job is used as described in the modification 2 (see FIG. 12) of the first embodiment described above. It may be a thing.
