  In the present embodiment, the image display device of the display unit 13 performs an operation of selecting, via the operation unit 7, an icon displayed as an image or a menu displayed as a character by the user. A so-called GUI (Graphical User Interface) for inputting an instruction to the apparatus 1 is displayed. The GUI image is generated by the control unit 4.

  The wireless communication unit 2 is configured to be able to communicate electronic data with an external device that is another electronic device different from the information communication device 1 by a predetermined type of wired communication means or wireless communication means. The wireless communication unit 2 can communicate with an external device via a plurality of network lines, and is configured to attach identification information to each of the plurality of network lines.

  In this embodiment, as an example, the wireless communication unit 2 can perform wireless communication with an external device by a wireless LAN based on a known standard such as IEEE802.11a, IEEE802.11b, IEEE802.11g, IEEE802.15, or the like. It is configured. Hereinafter, the network line to which the wireless communication unit 2 is connected is referred to as a wireless network.

  In this embodiment, the wireless communication unit 2 can serve as a plurality of wireless LAN access points that are a plurality of wireless networks, and each of the plurality of wireless LAN access points has different identification information. SSID (Service Set IDentification) is attached.

  Specifically, in the present embodiment, the wireless communication unit 2 can be a wireless LAN access point A whose SSID is “SSID-A” and a wireless LAN access point B whose SSID is “SSID-B”. It is configured. Hereinafter, the wireless LAN with the SSID “SSID-A” is referred to as a wireless network A, and the wireless LAN with the SSID “SSID-B” is referred to as a wireless network B. SSID-A and SSID-B may be in a so-called broadcast state that informs the surroundings, or may be in a so-called stealth state that does not inform the surroundings.

  Here, the wireless network A and the wireless network B may be encrypted, or may not be encrypted. In this embodiment, as an example, the wireless network A is not encrypted, and any external device is set to be able to participate without requiring authentication. On the other hand, the wireless network B is encrypted based on a known standard, and the external device is set so that it cannot participate unless a predetermined passphrase is input.

  The SSID of the wireless network that serves as an access point for the wireless communication unit 2, the setting of whether or not the wireless network is encrypted, and the passphrase may be fixed or may be changed by the user.

In the present embodiment, the operation unit 7 includes a power operation switch 7a for switching on / off the power of the information communication device 1, a wireless communication changeover switch 7b for switching presence / absence of operation of the wireless communication unit 2, and an information communication device. 1 and a reproduction operation instruction unit 7c for inputting an instruction of a file reproduction operation by 1.

  Note that a part or all of the operation unit 7 may be realized by a GUI. For example, the wireless communication changeover switch 7b and the reproduction operation instruction unit 7c are realized by a mode in which an icon or menu displayed on the image display device is selected and operated by a touch panel provided on the image display device of the display unit 13. There may be.

  The operation unit 7 may be in the form of a so-called remote controller that inputs an operation instruction to the information communication apparatus 1 by wireless communication using infrared rays or radio waves.

  Next, a detailed description of the control unit 4 and an operation of the information communication apparatus 1 controlled by the control unit 4 will be described. The control unit 4 includes an input / output unit 4b, a storage area management unit 4c, a file management unit 4d, a wireless communication management unit 4e, a reproduction output unit 4f, and an information processing unit 4a.

  The input / output unit 4 b is a part that controls communication between the control unit 4 and each unit of the information communication device 1.

  The storage area management unit 4 c is configured to provide a public area RO and a private area RC in the storage device 10 connected to the storage device connection unit 3.

  The public area RO is composed of one or a plurality of areas that can contain an arbitrary number of files. The non-public area RC can include an arbitrary number of files, and includes one or a plurality of areas different from the public area RO.

  Here, the format for distinguishing the public area RO and the private area RC is not particularly limited. For example, each of the public area RO and the private area RC is a different directory (folder) in the file system configured in the storage device 10, and the public area RO and the private area RC are composed of a plurality of logically different areas. Form may be sufficient. Further, for example, the public area RO and the private area RC may be configured by a plurality of partitions obtained by logically dividing the storage area of the same storage device 10. Further, the public area RO and the private area RC may be areas respectively provided in a plurality of physically different storage devices 10 connected to the storage device connection unit 3. Further, for example, the public area RO and the private area RC may be apparent areas configured by a set of files distributed based on metadata values.

  In the present embodiment, as an example, as shown in FIG. 2, there is one storage device 10 connected to the storage device connection unit 3, and the public area RO and the private area RC are in the storage area of the storage device 10. Are two different directories. In the present embodiment shown in FIG. 2, the directory name that is the public area RO is “DCIM”, and the directory name that is the private area RC is “SECRET”.

  Then, the storage area management unit 4c publishes a file stored in the storage device 10 connected to the storage device connection unit 3 on a wireless network where the wireless communication unit 2 serves as an access point according to a predetermined condition. It is configured to be able to. In other words, the storage area management unit 4 c is configured to be able to control whether or not an external device connected via the wireless communication unit 2 can access a file stored in the storage device 10. That is, the storage area management unit 4c has a function as a file server.

  Specifically, the storage area management unit 4c publishes the file included in the public area RO on the wireless network with the predetermined first identification information, and is included in the non-public area RC. The file is configured not to be disclosed on the wireless network to which the first identification information is attached. Here, the first identification information is an SSID which is “SSID-A” in the present embodiment.

  Therefore, in the present embodiment, the storage area management unit 4c publishes only the files included in the public area RO on the wireless network A whose SSID is “SSID-A”, and is included in the private area RC. The file is not disclosed on the wireless network A. That is, the external device 200 participating in the wireless network A can access the file included in the public area RO, but can access the file included in the private area RC. I can not.

  As described above, in the information communication apparatus 1 according to the present embodiment, for example, when a user saves a file in the public area RO of the storage device 10 and operates the wireless communication unit 2 and the storage area management unit 4c, the file Can be disclosed to surrounding external devices 200 via the wireless network A. Here, as described above, since the wireless network A is not encrypted and the external device can participate freely without requiring authentication, the wireless communication unit 2 and the storage area management unit 4c operate. In such a case, the external device 200 can freely access the file stored in the public area RO.

  Further, in the present embodiment, the storage area management unit 4c stores the files included in the public area RO and the private area RC on the wireless network to which the second identification information different from the first identification information is attached. It is configured to be open to the public. The second identification information is an SSID that is “SSID-B” in the present embodiment.

  Therefore, in the present embodiment, the storage area management unit 4c operates to publish the files included in the public area RO and the private area RC on the wireless network B whose SSID is “SSID-B”. . That is, the external device 201 participating in the wireless network B can access the files included in both the public area RO and the private area RC.

  In the present embodiment, the public area RO and the private area RC are the “DCIM” directory and the “SECRET” directory, respectively. However, the form in which the public area RO and the private area RC are separated depends on the directory. This is not limited to the above. For example, as shown in FIG. 3, on the file system or on the interface for accessing the information communication apparatus 1 from an external device, an apparent region that is a set of files that can be read from the external device is a public region RO. There may be a form in which an apparent area that is a set of files that cannot be read from an external device is a private area RC.

  Specifically, in the modification shown in FIG. 3, the public area RO is a set of files to which access permission information indicating that access from an external device connected to the wireless networks A and B is possible. In the modification shown in FIG. 3, the private area RC is a set of files to which access permission information indicating that access from an external device connected to the wireless network A is impossible is added. The storage area management unit 4c controls whether or not an external device connected to the wireless network A can access the file based on the content of the access permission information that is the metadata of the file.

  Here, in the present embodiment shown in FIG. 2, as described above, the storage area management unit 4 c performs wireless communication based on information on which directory each file stored in the storage device 10 is included in. It controls whether or not an external device connected to the network A can access a file. That is, in the present embodiment shown in FIG. 2, it can be said that the information indicating in which directory each file stored in the storage device 10 is included is the access permission information attached to the file. The access permission information attached to the file as in the present embodiment shown in FIG. 2 or a modification of the present embodiment shown in FIG. 3 is a well-known technique in the file system, and detailed description thereof will be omitted. And

  As described above, the wireless network B is encrypted and set so that it cannot participate unless a predetermined passphrase is input. Therefore, in the information communication device 1 according to the present embodiment, the file included in the private area RC that cannot be accessed from the external device 200 among the files stored in the storage device 10 is identified with respect to the authenticated specific external device 201. Can be made public.

  For example, in the present embodiment illustrated in FIG. 5, the external device 200 participating in the wireless network A is included in the File01. It is possible to read a file such as jpg, but File07. gif cannot be read. In the present embodiment illustrated in FIG. 5, the external device 201 participating in the wireless network B can read files included in both the public area RO and the private area RC.

  The file management unit 4d is configured to be able to perform operations such as creating, changing, deleting, and moving directories and files in the storage area of the storage device 10. The file management unit 4d is configured to be able to change metadata such as access permission information attached to a file stored in the storage device 10.

  The wireless communication management unit 4e is configured to be able to control the operation of the wireless communication unit 2. The wireless communication management unit 4e switches whether or not power is supplied to the wireless communication unit 2 and whether or not the access point of the wireless communication unit 2 is operating.

  The reproduction output unit 4f is configured to reproduce and output a file having a predetermined format or a plurality of formats (modes) out of files stored in the storage device 10. The file reproduced by the reproduction output unit 4 f is output to the display unit 13 via the external device interface 5. The user can view the reproduced file on the image display device of the display unit 13.

  The format of the file that can be reproduced and output by the reproduction output unit 4f is not particularly limited. In the present embodiment, as an example, the reproduction output unit 4f includes a JPEG still image file having an extension of jpg and an extension. It is assumed that a moving image file in the AVI container format whose child is avi can be reproduced and output to the display unit 13. The reproduction output unit 4f of the present embodiment is a file other than the above format, for example, a document file having an extension of txt, a GIF format still image file having an extension of gif, and an MP4 format moving image having an extension of mp4. It is assumed that image files cannot be reproduced.

  Note that this is an example, and it goes without saying that the format of the file that can be reproduced by the reproduction output unit 4f is not limited to this embodiment. The playback output unit 4f can play back and output a file of a predetermined format or a plurality of formats, but the format of the playable file may be changeable. For example, the format of a file that can be reproduced by the reproduction output unit 4f can be changed by adding or rewriting a program executed by the control unit 4.

  The information processing unit 4a is configured to control the operation of each part of the information communication device 1 according to a predetermined program.

  The process shown in FIG. 4 is started when the power supply from the power supply unit 14 to the information communication apparatus 1 is started. In this embodiment, as an example, when the user operates the power operation switch 7a, power supply from the power supply unit 14 to the information communication apparatus 1 is started.

  First, in step S01, an initialization operation necessary for starting the parts constituting the information communication apparatus 1 is executed. In the present embodiment, it is assumed that the supply of power to the wireless communication unit 2 is stopped in the state where the initialization operation in step S01 is completed.

  Next, in step S02, it is determined whether or not an operation start instruction for the wireless communication unit 2 has been input. The operation start instruction for the wireless communication unit 2 may be input by operating the wireless communication changeover switch 7b by the user, or a predetermined condition may be set in the control unit 4. When it determines with satisfy | filling, the form which the control part 4 automatically generate | occur | produces the operation start instruction | indication of the radio | wireless communication part 2 may be sufficient.

  For example, the control unit 4 may be configured to always issue an operation start instruction of the wireless communication unit 2 after the initialization operation of step S01 is completed, or a predetermined signal is input via the external device interface 5 In such a case, an operation start instruction for the wireless communication unit 2 may be generated.

  In the present embodiment, as an example, it is assumed that an operation start instruction of the wireless communication unit 2 is input when the user operates the wireless communication changeover switch 7b. In the present embodiment, since the wireless network A and the wireless network B are started when the wireless communication unit 2 is operated, step S02 determines whether or not an instruction to start the wireless network A is input. In other words, it is a process of determining whether or not.

  If it is determined in step S02 that the operation start instruction for the wireless communication unit 2 has not been input, the process proceeds to step S03. In step S03, it is determined whether or not a stop instruction for the wireless communication unit 2 has been input. That is, in step S03, it is determined whether or not an instruction to stop the wireless network A is input. In the present embodiment, as an example, an instruction to stop the wireless communication unit 2 is input when the user operates the wireless communication changeover switch 7b.

  The input of the stop instruction of the wireless communication unit 2 may be in a form that is automatically generated by the control unit 4 when the control unit 4 determines that a predetermined condition is satisfied. For example, the control unit 4 generates an instruction to turn off the information communication device 1 when the operation unit 7 is not operated for a predetermined time or when a predetermined signal is input through the external device interface 5. It may be a form to do.

  If it is determined in step S03 that a stop instruction for the wireless communication unit 2 has not been input, the process proceeds to step S04. In step S04, it is determined whether or not an instruction to turn off the power of the information communication apparatus 1 has been input. In the present embodiment, as an example, an instruction to turn off the power of the information communication apparatus 1 is input by the user operating the power operation switch 7a.

  The instruction to turn off the power of the information communication apparatus 1 may be in a form that is automatically generated by the control unit 4 when the control unit 4 determines that a predetermined condition is satisfied. For example, the control unit 4 may be configured to generate an instruction to turn off the power of the information communication device 1 when a predetermined signal is input via the external device interface 5.

  If it is determined in step S04 that an instruction to turn off the information communication apparatus 1 is not input, the process returns to step S02. That is, the above-described steps S02, S03, and S04 are steps for waiting until an instruction to operate or stop the wireless communication unit 2 or an instruction to turn off the power is input.

  And when it determines with the instruction | indication which turns off the power supply of the information communication apparatus 1 having been input (YES of step S04), it transfers to step S05 and performs the completion | finish process which turns off the power supply of the information communication apparatus 1. .

  When it is determined that a stop instruction for the wireless communication unit 2 has been input (YES in step S03), the process proceeds to step S10. In step S10, it is determined whether or not the wireless communication unit 2 is operating. If it is determined in step S10 that the wireless communication unit 2 is in a stopped state, that is, the wireless network A is in a stopped state, the process proceeds to step S04.

  If it is determined in step S10 that the wireless communication unit 2 is in operation, that is, the wireless network A is in operation, the process proceeds to step S11. In step S11, the operation of the wireless communication unit 2 is stopped. That is, the wireless network A and the wireless network B are stopped. Thereafter, the process proceeds to step S04.

  On the other hand, when it determines with the operation start instruction | indication of the radio | wireless communication part 2 having been input (YES of step S02), it transfers to step S20. In step S20, it is determined whether or not the wireless communication unit 2 is already operating. If it is determined in step S20 that the wireless communication unit 2 is in operation, that is, the wireless network A is in operation, the process returns to step S03.

  If it is determined in step S20 that the wireless communication unit 2 is in a stopped state, that is, the wireless network A is in a stopped state, the process proceeds to step S21. In step S21, it is confirmed whether or not all the files included in the public area RO of the storage device 10 can be reproduced by the reproduction output unit 4f.

  Then, in step S22, based on the result of step S21, it is determined whether or not there is something that cannot be reproduced by the reproduction output unit 4f in the public area RO of the storage device 10.

  If it is determined in step S22 that there is no non-reproducible object in the public area RO by the reproduction output unit 4f, the process skips step S23 and proceeds to step S24 to start operation of the wireless communication unit 2. Then, the wireless network A and the wireless network B are started. Then, the process proceeds to step S04.

  On the other hand, if it is determined in step S22 that there is something that cannot be reproduced by the reproduction output unit 4f in the public area RO, the process proceeds to step S23. In step S23, all files in a format that cannot be reproduced by the reproduction output unit 4f among the files included in the public region RO are moved to the private region RC. Here, the movement of the file is an operation of deleting the migration source file after copying the migration source (public area RO) file to the migration destination (private area RC). This movement operation is performed by the file management unit 4d.

  In other words, in step S23, access permission information attached to all files in a format that cannot be reproduced by the reproduction output unit 4f among the files included in the public area RO is transmitted to the wireless network A. Is a process of changing to contents that are not disclosed.

  After execution of step S23, the process proceeds to step S24, the operation of the wireless communication unit 2 is started, and the wireless network A and the wireless network B are started. Then, the process proceeds to step S04.

  As described above, the information communication apparatus 1 according to the present embodiment can communicate with an external device via the wireless network A to which identification information SSID-A is attached and the wireless network B to which identification information SSID-B is attached. The wireless communication unit 2 configured to be communicable, the storage device connection unit 3 that performs input / output between the storage device 10, and the control unit 4 are configured.

  In addition, the control unit 4 includes a storage area management unit 4c configured to provide the storage device 10 with a public area RO for publishing files on the wireless network A and a private area RC for not publishing files on the wireless network A. A reproduction output unit 4f configured to reproduce and output a file in a predetermined format or a plurality of formats stored in the storage device 10, and to move the file stored in the storage device 10 And a file management unit 4d configured as described above.

  Then, when the wireless network A is started, the file management unit 4d converts a file in a format that cannot be reproduced and output by the reproduction output unit 4f among the files included in the public region RO into the private region RC. Is configured to move. In other words, when the wireless network A is started, the file management unit 4d grants access permission to a file in a format that cannot be reproduced and output by the reproduction output unit 4f among the files included in the public area RO. The information is configured to be changed to contents that are not disclosed to the wireless network A.

  Here, in the information communication apparatus 1 of the present embodiment having the above configuration, for example, it is assumed that a plurality of files as shown in FIG. Specifically, in the public area RO of the storage device 10, File01. jpg, File02. gif, File03. avi, File04. mp4, File05. txt and File06. jpg is included.

  That is, in the public area RO, File02. gif, File04. mp4 and File05. A file in a format that cannot be reproduced and output by the three reproduction output units 4f including txt is included. In this state, since the wireless network A and the wireless network B are stopped, the file in the open area RO is not released on the wireless network A.

  When the information communication apparatus 1 in this state determines that an operation start instruction for the wireless communication unit 2 has been input, the above-described step S23 is executed, and reproduction output cannot be performed by the three reproduction output units 4f. A file of the form is moved to the private area RC. As described above, a file in a format that cannot be reproduced and output by the reproduction output unit 4f is deleted from the public area RO before the operation of the wireless network A, and therefore is not disclosed on the wireless network A (FIG. 6).

  For example, in a conventional information communication device, a file that the user does not want to make public on the wireless network is included in the public area of the storage device, and the file cannot be reproduced and output by the information communication device. In some cases, the user may not be aware that the file that he does not want to publish is included in the public area. In the conventional information communication apparatus, there is a possibility that a file that is not desired to be disclosed is disclosed on the wireless network.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the following, only differences from the first embodiment will be described, and the same components as those in the first embodiment will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

  The configuration of the information communication apparatus 1 of this embodiment is the same as that of the first embodiment shown in FIG. 1 or FIG. The operation of the information communication apparatus 1 of this embodiment will be described with reference to the flowchart shown in FIG.

  The process shown in FIG. 8 is started when the power supply from the power supply unit 14 to the information communication apparatus 1 is started. In this embodiment, as an example, when the user operates the power operation switch 7a, power supply from the power supply unit 14 to the information communication apparatus 1 is started.

  First, in step S01, an initialization operation necessary for starting the parts constituting the information communication apparatus 1 is executed. In the present embodiment, it is assumed that the supply of power to the wireless communication unit 2 is stopped in the state where the initialization operation in step S01 is completed.

  Next, in step S02, it is determined whether or not an operation start instruction for the wireless communication unit 2 has been input. The operation start instruction for the wireless communication unit 2 may be input by operating the wireless communication changeover switch 7b by the user, or a predetermined condition may be set in the control unit 4. When it determines with satisfy | filling, the form which the control part 4 automatically generate | occur | produces the operation start instruction | indication of the radio | wireless communication part 2 may be sufficient.

  For example, the control unit 4 may be configured to always issue an operation start instruction of the wireless communication unit 2 after the initialization operation of step S01 is completed, or a predetermined signal is input via the external device interface 5 In such a case, an operation start instruction for the wireless communication unit 2 may be generated.

  In the present embodiment, as an example, it is assumed that an operation start instruction of the wireless communication unit 2 is input when the user operates the wireless communication changeover switch 7b. In the present embodiment, since the wireless network A and the wireless network B are started when the wireless communication unit 2 is operated, step S02 determines whether or not an instruction to start the wireless network A is input. In other words, it is a process of determining whether or not.

  If it is determined in step S02 that the operation start instruction for the wireless communication unit 2 has not been input, the process proceeds to step S03. In step S03, it is determined whether or not a stop instruction for the wireless communication unit 2 has been input. That is, in step S03, it is determined whether or not an instruction to stop the wireless network A is input. In the present embodiment, as an example, an instruction to stop the wireless communication unit 2 is input when the user operates the wireless communication changeover switch 7b.

  The input of the stop instruction of the wireless communication unit 2 may be in a form that is automatically generated by the control unit 4 when the control unit 4 determines that a predetermined condition is satisfied. For example, the control unit 4 generates an instruction to turn off the information communication device 1 when the operation unit 7 is not operated for a predetermined time or when a predetermined signal is input through the external device interface 5. It may be a form to do.

  If it is determined in step S03 that a stop instruction for the wireless communication unit 2 has not been input, the process proceeds to step S04. In step S04, it is determined whether or not an instruction to turn off the power of the information communication apparatus 1 has been input. In the present embodiment, as an example, an instruction to turn off the power of the information communication apparatus 1 is input by the user operating the power operation switch 7a.

  The instruction to turn off the power of the information communication apparatus 1 may be in a form that is automatically generated by the control unit 4 when the control unit 4 determines that a predetermined condition is satisfied. For example, the control unit 4 may be configured to generate an instruction to turn off the power of the information communication device 1 when a predetermined signal is input via the external device interface 5.

  If it is determined in step S04 that an instruction to turn off the information communication apparatus 1 is not input, the process returns to step S02. That is, the above-described steps S02, S03, and S04 are steps for waiting until an instruction to operate or stop the wireless communication unit 2 or an instruction to turn off the power is input.

  And when it determines with the instruction | indication which turns off the power supply of the information communication apparatus 1 having been input (YES of step S04), it transfers to step S05 and performs the completion | finish process which turns off the power supply of the information communication apparatus 1. .

  When it is determined that an operation start instruction for the wireless communication unit 2 has been input (YES in step S02), the process proceeds to step S20. In step S20, it is determined whether or not the wireless communication unit 2 is already operating. If it is determined in step S20 that the wireless communication unit 2 is in operation, that is, the wireless network A is in operation, the process returns to step S03.

  If it is determined in step S20 that the wireless communication unit 2 is in a stopped state, that is, the wireless network A is in a stopped state, the process proceeds to step S21. In step S21, it is confirmed whether or not all the files included in the public area RO of the storage device 10 can be reproduced by the reproduction output unit 4f.

  Then, in step S22, based on the result of step S21, it is determined whether or not there is something that cannot be reproduced by the reproduction output unit 4f in the public area RO of the storage device 10.

  In step S22, when it is determined that there is no non-reproducible object in the public area RO by the reproduction output unit 4f, the process skips step S23 and step S41 and proceeds to step S24. The operation is started and the wireless network A and the wireless network B are started. Then, the process proceeds to step S04.

  On the other hand, if it is determined in step S22 that there is something that cannot be reproduced by the reproduction output unit 4f in the public area RO, the process proceeds to step S23. In step S23, all files in a format that cannot be reproduced by the reproduction output unit 4f among the files included in the public region RO are moved to the private region RC. Here, the movement of the file is an operation of deleting the migration source file after copying the migration source (public area RO) file to the migration destination (private area RC). This movement operation is performed by the file management unit 4d.

  In other words, in step S23, access permission information attached to all files in a format that cannot be reproduced by the reproduction output unit 4f among the files included in the public area RO is transmitted to the wireless network A. Is a process of changing to contents that are not disclosed.

  In step S41, the information of the file moved in step S23 is stored. In other words, in step S41, information related to the file whose access permission information is changed in step S23 is stored. Here, the format for storing the information of the file moved in step S23 is not particularly limited. For example, the file management unit 4d stores the list of files moved in step S23 as a list. Also good. Further, for example, the file management unit 4d may be configured to attach information indicating that the file is moved from the public area RO to the metadata of each file moved in step S23.

  In the present embodiment, as an example, the file management unit 4d assumes that the list of files moved in step S23 is listed and stored. After execution of step S41, the process proceeds to step S24, the operation of the wireless communication unit 2 is started, and the wireless network A and the wireless network B are started. Then, the process proceeds to step S04.

  On the other hand, when it determines with the stop instruction | indication of the radio | wireless communication part 2 having been input (YES of step S03), it transfers to step S10. In step S10, it is determined whether or not the wireless communication unit 2 is operating. If it is determined in step S10 that the wireless communication unit 2 is in a stopped state, that is, the wireless network A is in a stopped state, the process proceeds to step S04.

  In Step S10, when it is determined that the wireless communication unit 2 is in operation, that is, the wireless network A is in operation, the process proceeds to Step S31. In step S31, the presence of a file that has been moved from the public area RO as a result of the execution of step S23 is confirmed for the files included in the private area RC. In step S32, it is determined whether or not there is a file moved from the public area RO as a result of the execution of step S23 in the non-public area RC.

  In step S31 and step S32, in the present embodiment, if the file management unit 4d stores the list of files moved in step S23, the file moved from the public area RO exists in the private area RC. Will be.

  If it is determined in step S32 that the file moved from the public area RO does not exist in the non-public area RC, the process proceeds to step S11 and the operation of the wireless communication unit 2 is stopped. That is, the wireless network A and the wireless network B are stopped. Thereafter, the process proceeds to step S04.

  On the other hand, if it is determined in step S32 that the file moved from the public area RO exists in the private area RC, the public area is included in the private area RC as a result of the execution of step S23. All files moved from the RO are moved to the public area RO.

  That is, in step S32, as a result of the execution of step S23, the access permission information is disclosed to the wireless network A for all the files whose access permission information has been changed to be not disclosed to the wireless network A. Change to content.

  Next, the process proceeds to step S34, and the file list moved in step S23 stored in the file management unit 4d is deleted. And it transfers to step S11 and the operation | movement of the radio | wireless communication part 2 is stopped. That is, the wireless network A and the wireless network B are stopped. Thereafter, the process proceeds to step S04.

  The information communication apparatus 1 according to the present embodiment described above includes all the files that have been moved from the public area RO as a result of the execution of step S23 included in the private area RC when the wireless network A is stopped. Is different from the first embodiment in that it is configured to move to the public area RO.

  In the present embodiment, as described in the first embodiment, when the information communication apparatus 1 in the state illustrated in FIG. 5 determines that the operation start instruction for the wireless communication unit 2 is input, the above-described step S23 is performed. , And a file in a format that cannot be reproduced and output by the reproduction output unit 4f is moved from the public area RO to the private area RC. When the wireless communication unit 2 is in operation, the state shown in FIG. In the present embodiment, when the information communication apparatus 1 in the state shown in FIG. 6 determines that a stop instruction for the wireless communication unit 2 has been input, all files moved from the public area RO to the private area RC. Is moved back to the public area RO.

  In other words, in the information communication apparatus 1 of the present embodiment, a file in a format that cannot be reproduced and output by the reproduction output unit 4f included in the public area RO only during the period when the wireless network A is operating. It is temporarily moved to the private area RC.
