When “restriction presence / absence” 68 is “x”, normal content whose operation is not restricted. Indicates.

  The “authentication method” 69 is information indicating an authentication method for releasing the restriction on the operation of restricted content. Examples of the authentication method include a method of collating a user's voice, a method of collating a user's fingerprint, a method of collating a password set by the user, and a method of collating an image set by the user. In addition, a method of collating the order in which the user touches a predetermined position on the screen, a method of collating a locus touched on the screen by the user, or the like may be used.

  The “authentication data” 70 is authentication data used for authentication for releasing the restriction on the operation of the restricted content, and is information indicating authentication data set in advance by the user.

  The “restriction release effective range” 71 is information indicating a range in which the restriction release state where the restriction is released continues after the restriction on the operation of the restricted content is released. The range in which the restriction release state continues may be, for example, a predetermined period after the restriction is released, the number of user operations after the restriction is released, or a restriction in which the operation is restricted from the restriction release state. It may be a condition for switching to a state. The condition for switching from the restriction release state to the restriction state may be, for example, when the communication application to be placed ends, when the two terminals are separated (no longer in a multi-layer state), or when the communication connection between the two terminals is disconnected But you can.

  The “restriction release flag” 72 is information indicating whether a restriction release state in which the restriction of restricted content operation is released or a restriction state in which restricted content operation is restricted. In the illustrated example, when the “restriction release flag” 72 is “T”, it indicates that the restricted content is in a restricted release state. When the “restriction release flag” 72 is “F”, the restricted content is in a restricted state. It shows that.

  In the example shown in FIG. 4, “restriction presence / absence” 68, “authentication method” 69, “authentication data” 70, “restriction release effective range” 71, and “restriction release flag” 72 are respectively set for each content. It is set but not limited to this. For example, it may be set for each of a plurality of contents or for each mobile phone.

  When the authentication data is input (YES in S442), the input operation specifying unit 33A outputs the acquired authentication data to the authentication unit 36A. The authentication unit 36A transmits the acquired authentication data to the mobile phone 1B via the short-range wireless communication unit 14A as a response to the received authentication data request instruction (S443).

  On the other hand, after transmitting the authentication data request instruction, the authentication unit 36B of the mobile phone 1B waits for the authentication data to be transmitted from the mobile phone 1A (S444).

  Here, when the authentication unit 36B receives the authentication data from the mobile phone 1A (YES in S444), the authentication unit 36B reads the authentication data associated with the content identification information included in the content entity data request instruction from the storage unit 12B. It is determined whether the read authentication data matches the received authentication data (S445).

  If the read authentication data matches the received authentication data (YES in S445), the authentication unit 36B releases the restriction on the restricted content operation indicated by the content identification information included in the content entity data request instruction, The content transmission unit 44B is notified that the restriction on the operation of the restricted content has been released. When notified from the authentication unit 36B that the restriction on the operation of the restricted content has been released, the content transmitting unit 44B receives from the storage unit 12B the shared content (restricted content) indicated by the content identification information included in the content entity data request instruction. In response to the received content entity data request instruction, the read shared content entity data is transmitted to the mobile phone 1A via the short-range wireless communication unit 14B (S446).

  Further, when the restriction of the restricted content is released, the authentication unit 36B sets a restriction release flag for the restricted content whose restriction has been released, and updates the content information of the restricted content stored in the storage unit 12B (S447).

  On the other hand, after the authentication unit 36A transmits the authentication data, the content acquisition unit 43A of the mobile phone 1A waits for the shared content entity data to be transmitted from the mobile phone 1B (S448).

  When the content acquisition unit 43A receives the entity data of the shared content specified by the operation display information to be operated as a response to the content entity data request instruction (YES in S448), the content acquisition unit 43A stores the received entity data of the shared content. It is stored in 12A (S437). Also, when the content acquisition unit 43A receives the entity data of the shared content, the content acquisition unit 43A notifies the display control unit 32A to that effect.

  When the display control unit 32A is notified from the content acquisition unit 43A that the entity data of the shared content specified by the operation target operation display information has been received, the display control unit 32A displays the operation target operation display information in the first display area. Is added and displayed (S438).

  By the way, if authentication data is not input to the mobile phone 1A in S442 (NO in S442), the authentication unit 36A authenticates the display control unit 32A to notify the user that authentication could not be performed. Instructs the error screen to be displayed. The display control unit 32A displays an authentication error screen on the main display unit 13aA based on an instruction from the authentication unit 36A (S449).

  The display control unit 32A displays the authentication error screen on the main display unit 13aA, and then displays the shared content of the mobile phone 1A and the mobile phone 1B again in the first display area and the second display area, respectively. At this time, the display control unit 32A adds and displays the authentication display information to the operation display information to be operated (S450).

  If the authentication data is not transmitted to the mobile phone 1B in S444 (NO in S444), the authentication unit 36B sends an authentication error notification indicating that the authentication could not be performed via the short-range wireless communication unit 14B. This is transmitted to the telephone 1A (S451). In S445, also when the read authentication data does not match the received authentication data (NO in S445), the authentication unit 36B transmits an authentication error notification to the mobile phone 1A (S451).

  In S448, when the content acquisition unit 43A of the mobile phone 1A does not receive the entity data of the shared content and the authentication unit 36A receives the authentication error notification (NO in S448), the authentication unit 36A displays the display control unit 32A. Is instructed to display an authentication error screen based on the received authentication error notification. The display control unit 32A displays an authentication error screen on the main display unit 13aA based on an instruction from the authentication unit 36A (S449).

  The display control unit 32A displays the authentication error screen on the main display unit 13aA, and then displays the shared content of the mobile phone 1A and the mobile phone 1B again in the first display area and the second display area, respectively. At this time, the display control unit 32A adds and displays the authentication display information to the operation display information to be operated (S450).

  By the way, in S431, after the shared content is displayed, the input operation specifying unit 33A of the mobile phone 1A receives the operation display information displayed in the first display area from the optical sensor 17aA, the operation unit 16aA, or the voice input unit 23A. When the operation instruction to move to the 2 display area is acquired (NO in S431), the content processing unit 35A is notified accordingly.

  When the operation instruction to move the display information for operation displayed in the first display area to the second display area is notified from the input operation specifying section 33A, the content processing unit 35A is specified by the display information for operation to be operated. Then, “content transmission processing to the lower terminal in the upper terminal” (details will be described later) is executed to transmit the actual data of the shared content to the mobile phone 1B (S452).

  On the other hand, when the content acquisition unit 43B of the mobile phone 1B receives the shared content entity data from the mobile phone 1A (NO in S433), the content acquisition unit 43B stores the received shared content entity data in the storage unit 12B (S453).

[Content transmission processing to the lower terminal in the upper terminal]
Next, based on FIG. 12, the content transmission process to the lower terminal in an upper terminal is demonstrated in detail. As shown in FIG. 12, the content transmitting unit 44A of the content processing unit 35A is notified of an operation instruction for moving the operation display information displayed in the first display area to the second display area from the input operation specifying unit 33A. Then, it is specified whether the shared content specified by the operation display information to be operated is normal content or restricted content (S461).

  Here, when the shared content specified by the operation display information to be operated is normal content (NO in S461), the content transmission unit 44B is specified by the operation display information to be operated from the storage unit 12B. The entity data of the shared content (normal content) is read, and the read entity data of the shared content is transmitted to the mobile phone 1B via the short-range wireless communication unit 14A (S462). Further, when the content transmission unit 44A transmits the entity data of the shared content, the content transmission unit 44A notifies the display control unit 32A to that effect.

  When the display control unit 32A is notified from the content transmission unit 44A that the substance data of the shared content specified by the operation display information to be operated is transmitted, the display control unit 32A displays the operation display information to be operated in the second display area. Is displayed in addition to (S463).

  On the other hand, in S461, when the shared content specified by the operation display information to be operated is restricted content (YES in S461), the content transmission unit 44A refers to the content information stored in the storage unit 12A. Then, it is confirmed whether or not the restriction release flag associated with the content identification information of the restricted content specified by the operation display information to be operated is set (S464).

  Here, when the restriction release flag associated with the content identification information of the restricted content specified by the operation display information to be operated is set (YES in S464), the content transmission unit 44B reads from the storage unit 12B. Then, the entity data of the shared content (restricted content) specified by the operation display information to be operated is read, and the read entity data of the shared content is transmitted to the mobile phone 1B via the short-range wireless communication unit 14A ( S462). Further, when the content transmission unit 44A transmits the entity data of the shared content, the content transmission unit 44A notifies the display control unit 32A to that effect.

  When the display control unit 32A is notified from the content transmission unit 44A that the substance data of the shared content specified by the operation display information to be operated is transmitted, the display control unit 32A displays the operation display information to be operated in the second display area. Is displayed in addition to (S463).

  On the other hand, in S464, if the restriction release flag associated with the content identification information of the restricted content specified by the operation display information to be operated is not set (NO in S464), the content transmission unit 44A determines that the Is notified to the authentication unit 36A.

  When the authentication unit 36A is notified from the content transmission unit 44A that the restriction release flag associated with the content identification information of the restricted content specified by the operation display information to be operated is not set, the display control unit 32 A is instructed to display an authentication data input screen for allowing the user to input authentication data used for authentication for releasing the restriction of the restricted content specified by the operation display information to be operated. The display control unit 32A displays an authentication data input screen on the main display unit 13aA based on an instruction from the authentication unit 36A (S465).

  Here, the input operation specifying unit 33A waits for input of authentication data from the user via the optical sensor 17aA, the operation unit 16aA, or the voice input unit 23A (S466).

  When the authentication data is input (YES in S466), the input operation specifying unit 33A outputs the acquired authentication data to the authentication unit 36A. When the authentication unit 36A acquires the authentication data, the authentication unit 36A reads out the authentication data associated with the content identification information of the restricted content specified by the operation display information to be operated from the storage unit 12A, It is determined whether or not the acquired authentication data matches (S467).

  When the read authentication data matches the acquired authentication data (YES in S467), the authentication unit 36A releases the restriction on the operation of the restricted content specified by the operation display information to be operated, and the restriction The content transmission unit 44A is notified that the restriction on the content operation has been released. When notified from the authentication unit 36A that the restriction on the operation of the restricted content has been released, the content transmitting unit 44A, from the storage unit 12A, identifies the shared content (restricted content) identified by the operation display information to be operated. The data is read, and the real data of the read shared content is transmitted to the mobile phone 1B via the short-range wireless communication unit 14A (S468). Further, when the content transmission unit 44A transmits the entity data of the shared content, the content transmission unit 44A notifies the display control unit 32A to that effect.

  When the display control unit 32A is notified from the content transmission unit 44A that the substance data of the shared content specified by the operation display information to be operated is transmitted, the display control unit 32A displays the operation display information to be operated in the second display area. Is displayed in addition to (S469).

  Further, when the restriction of the restricted content is released, the authentication unit 36A sets a restriction release flag of the restricted content for which the restriction is released, and updates the content information of the restricted content stored in the storage unit 12A (S470).

  On the other hand, if the authentication data is not input to the mobile phone 1A in S466 (NO in S466), the authentication unit 36A authenticates the display control unit 32A to notify the user that the authentication could not be performed. Instructs the error screen to be displayed. The display control unit 32A displays an authentication error screen on the main display unit 13aA based on an instruction from the authentication unit 36A (S471).

  The display control unit 32A displays the authentication error screen on the main display unit 13aA, and then displays the shared content of the mobile phone 1A and the mobile phone 1B again in the first display area and the second display area, respectively. At this time, the display control unit 32A adds the authentication display information to the operation display information to be operated and displays it (S472).

  In S467, even when the read authentication data does not match the acquired authentication data (NO in S467), the authentication unit 36A indicates that the user cannot authenticate the display control unit 32A. To display an authentication error screen to notify Then, the display control unit 32A displays an authentication error screen on the main display unit 13aA based on an instruction from the authentication unit 36A (S471).

[Multilayer state maintenance judgment processing]
Finally, the determination process of whether or not the two mobile phones 1 in S6A and S6B maintain the multi-layer state will be described in detail.

  In S6A, the upper terminal state determination unit 41A continuously determines whether or not the optical sensor 17bA detects blinking display of the main display unit 13aB every predetermined period. If the optical sensor 17bA continuously detects blinking display, the upper terminal state determination unit 41A determines that the multistory state is maintained (NO in S6A). On the other hand, when the optical sensor 17bA no longer detects the blinking display, the upper terminal state determination unit 41A determines that the mobile phone 1A is separated from the mobile phone 1B (YES in S6A), and ends the communication application carried by the control unit 11A. (S7A).

  In S6B, the lower terminal state determination unit 42B continuously determines whether or not the optical sensor 17aB has detected a shadow for each predetermined period. The lower terminal state determination unit 42B determines that the multistory state is maintained if the optical sensor 17aB continuously detects shadows (NO in S6B). On the other hand, when the optical sensor 17aB no longer detects a shadow, the lower terminal state determination unit 42B determines that the mobile phone 1B has moved away from the mobile phone 1A (YES in S6B), and terminates the communication application carried by the control unit 11B ( S7B). In other words, the lower terminal state determination unit 42B determines that the mobile phone 1B has moved away from the mobile phone 1A when the optical sensor 17aB detects a predetermined amount or more of light (YES in S6B).

  However, the determination process of whether or not the multilayer state is maintained is not limited to this. For example, when the mobile phone 1 includes an acceleration sensor, it is determined whether or not the mobile phone 1 is moved a certain distance in a predetermined direction from the multi-layer state, and whether or not the multi-layer state is maintained is determined. Good. Further, when an instruction to end the communication application to be placed by the user is input, it may be determined that the user is not in the multi-layer state and the communication application to be placed may be terminated. Also, when one of the two mobile phones 1 is determined not to be in a multi-layer state or when the communication application to be placed is terminated, the determined or terminated mobile phone 1 notifies the other to that effect, It may be determined that the mobile phone 1 is not in the multi-layer state, or the communication application to be placed may be terminated.

[Display screen example]
Next, an example of a screen displayed on the main display unit 13aA in the multi-layer state will be described with reference to FIG. FIG. 13 is a diagram illustrating an example of a screen displayed on the main display unit 13aA of the mobile phone 1A in the multi-layer state.

  A state a shown in FIG. 13 is a normal state before the layered state. As illustrated, in this state a, it is assumed that the mobile phone 1A holds the shared contents CA1 and CA2, and the mobile phone 1B holds the shared contents CB1 and CB2. At this time, it is assumed that the operation of the shared content CB2 held by the mobile phone 1B is restricted. That is, among the shared contents held by the mobile phones 1A and 1B, the shared contents CA1, CA2, and CB1 are normal contents, and the shared contents CB2 are restricted contents.

  It is assumed that the cellular phone 1A is overlaid on the cellular phone 1B from the state a to be in a multilayered state (state b). As shown in FIG. 13, in the state b, the first display area in which the shared content held by the mobile phone 1A is displayed and the shared content held by the mobile phone 1B are displayed in the display area of the main display portion 13aA. A second display area WB is set. In the first display area WA, operation display information for specifying the normal contents CA1 and CA2 is displayed, and in the second display area WB, operation display information for specifying the normal content CB1 is displayed. Authentication display information is added to the display information for operation specifying the content CB2 and displayed.

  In the example illustrated in FIG. 13, in the state b, the authentication display information is added and displayed so as to cover the entire display information for operation specifying the restricted content CB2, but the present invention is not limited to this. For example, the authentication display information may be superimposed on the operation display information so as to cover a part of the operation display information, or the authentication display information may be added adjacent to the operation display information.

  In the state b, when the user performs an operation of touching the authentication display information added to the operation display information for specifying the restricted content CB2, the state transitions to the state c. As shown in FIG. 13, in the state c, the main display unit 13aA is caused to allow the user to input authentication data used for authentication for releasing the restriction of the restricted content CB2 to which the operation target authentication display information is added. The authentication data input screen is displayed.

  In the example shown in FIG. 13, in the state c, the authentication data input screen is displayed in the entire display area of the main display unit 13aA, but the present invention is not limited to this. The authentication data input screen may be displayed in a part of the display area of the main display portion 13aA, for example, the first display area WA or the second display area WB. The example shown in FIG. 13 is an authentication data input screen for performing authentication by fingerprint.

  In state c, it is assumed that the user has touched the screen to complete authentication. When the authentication for releasing the restriction on the operation of the restricted content CB2 is completed, the state transits to the state d. As shown in FIG. 13, in the state d, the restricted content CB2 displays only the operation display information with the authentication display information removed.

  If the user performs a drag operation from the second display area WB to the first display area WA from the state d, the state e transitions to the state e. As a result of this operation, the restricted content CB2 is copied to the mobile phone 1A. Therefore, as shown in FIG. 13, in the state e, the restricted content CB2 is displayed in the first display area in addition to the normal content CA1 and CA2. The

  As shown in FIG. 13, in the states b, d, and e, the display control unit 32 corresponds to the upper and lower positional relationships of the mobile phone 1A and the mobile phone 1B in the multi-layer state, and the first display area WA and The second display areas WB are respectively arranged so as to have a vertical positional relationship in the display area of the main display portion 13a. In the display area of the display unit, as shown in FIG. 13, the vertical direction is set, and the first display area WA is on the upper side and the second display area WB is on the lower side along the direction. Alternatively, the first display area WA and the second display area WB may be arranged in a state where a part of the second display area WB is superimposed below the first display area WA.

  Further, the first display area WA and the second display area WB are arranged in the display area of the main display unit 13a so as to correspond to the left and right positional relations in correspondence with the upper and lower positional relations of the mobile phone 1A and the mobile phone 1B in the multi-layer state. Each may be arranged so as to be.

  Further, in order to allow the user to understand that in the states b and c, the first display area WA and the second display area WB correspond to the mobile phone 1A and the mobile phone 1B, respectively, as shown in FIG. As described above, the display control unit 32 may display “A” indicating the mobile phone 1A in the first display area WA and display “B” indicating the mobile phone 1B in the second display area WB. For example, instead of displaying “A” indicating the mobile phone 1A in the first display area WA, the user name or the like of the mobile phone 1A may be displayed. Further, instead of displaying text information indicating the mobile phone 1A and the mobile phone 1B in the first display area WA and the second display area WB, the color of the frame of the first display area WA and the second display area WB and / or The background colors may be displayed in different colors so that the user can distinguish and recognize both. In this case, the color corresponding to the upper terminal and the color corresponding to the lower terminal may be set in advance, or the color may be set in advance for each user.

[Modification 1]
In the present embodiment, a mobile phone is exemplified as the information processing apparatus of the present invention, but the present invention is not limited to this. The information processing apparatus of the present invention only needs to include a display unit and a communication unit. For example, a PDA (Personal Digital Assistant), an electronic book terminal, a portable game machine, a digital camera, a digital TV, a notebook PC, portable music playback It may be a machine.

  In the present embodiment, the case where the two mobile phones 1 are the same model (size) is taken as an example, but the present invention is not limited to this. Different devices may be stacked, or devices of different sizes may be stacked. For example, a portable game machine may be stacked on a digital TV display to share the content, or mobile phones having different display units or housing sizes may be stacked to share the content. It may be.

  That is, the multi-layer state may be not only a state where the information processing apparatus overlaps with the whole of the other information processing apparatus but also a state where it overlaps with a part of the other information processing apparatus. In this case, hardware (sensors and the like) and software (multilayer state determination unit 31) for determining the multilayer state in the information processing apparatus may be appropriately designed.

[Modification 2]
In the present embodiment, two mobile phones 1 are stacked to share content. However, the present invention is not limited to this, and all the mobile phones 1 that are in a multi-layered state are stacked by stacking three or more mobile phones 1. You may make it share contents.

[Modification 3]
Further, the main display portion 13a of the mobile phone 1A may be configured with 3D liquid crystal. In this case, by displaying the shared content display area WA in front of the shared content display area WB, it is possible to display corresponding to the state of each mobile phone 1 in a multi-layered state, and the user operates more intuitively. be able to.

[Modification 4]
In the present embodiment, the content processing unit 35 moves and copies the shared content, but the present invention is not limited to this. For example, when the mail application is started from the state shown in FIG. 9B and the mobile phone 1A transmits mail to another device, the shared contents CA1, CA2, CB1, and CB2 of the mobile phones 1A and 1B are transmitted. You may make it possible to select it as an attached file. When CB1 or CB2 is selected as the attached file, the content acquisition unit 43A may request and acquire the content from the mobile phone 1B when sending the mail.

  When the content CB1 or CB2 is a moving image or music data, the content may be reproduced on the mobile phone 1A by the user inputting a content reproduction instruction from the state shown in FIG. 9B.

  Further, when the mobile phones 1A and 1B hold items used in the game application as shared content, the game application is started from the state shown in FIG. 9B and used in the game application. You may enable it to share an item etc. in a game.

  Further, electronic approval of the user of the mobile phone 1A or the user of the mobile phone 1B may be obtained by the user selecting content from the state shown in FIG. 9B. For example, electronic approval of the user of the mobile phone 1B may be added to the content CA1 by selecting the content CA1.

[Modification 5]
In the content processing example shown in FIG. 9 described above, when the operation display information to which the authentication display information is added is moved to another area, the user once performs an authentication operation to release the restriction. Although the operation for moving the operation display information to another area is performed later, the present invention is not limited to this. For example, an operation of moving the operation display information to which the authentication display information is added to another area may be performed. That is, authentication for releasing the restriction and content transmission / reception may be performed simultaneously or continuously.

  Specifically, when an operation instruction for moving the operation display information to which authentication display information is added to another area is input, the authentication unit 36A of the mobile phone 1A sends an authentication start request instruction to the mobile phone 1B. Then, after receiving the restriction release notification as a response to the authentication start request instruction, the content acquisition unit 43A may continuously transmit the content entity data request instruction to the mobile phone 1B. In this case, after the authentication unit 36B of the mobile phone 1B transmits the restriction release notification as a response to the authentication start request instruction, the content transmission unit 44B receives the content entity data request instruction and is included in the content entity data request instruction. When the content identification information matches the content identification information included in the restriction release notification transmitted by the authentication unit 36B, the restricted content indicated by the content identification information included in the content entity data request instruction is a response to the content entity data request instruction. Is transmitted to the mobile phone 1A.

  When an operation instruction for moving the operation display information to which the authentication display information is added to another area is input, the authentication unit 36A of the mobile phone 1A transmits an authentication start request instruction to the mobile phone 1B. The content acquisition unit 43A may transmit a content entity data request instruction to the mobile phone 1B. In this case, the authentication unit 36B of the mobile phone 1B may transmit the restriction release notification and the substance data of the restricted content to the mobile phone 1A when the authentication data matches.

  Note that the authentication unit 36B of the mobile phone 1B may transmit only the substance data of the restricted content to the mobile phone 1A when the authentication data matches. In this case, when the content acquisition unit 43A of the mobile phone 1A has acquired the substance data of the content, the authentication unit 36A determines that the restriction on the operation of the restricted content specified by the operation display information to be operated has been released. .

  When an operation instruction for moving the operation display information to which the authentication display information is added to another area is input, the authentication unit 36A of the mobile phone 1A transmits an authentication start request instruction to the mobile phone 1B. Until the authentication unit 36A receives the restriction release notification, the content acquisition unit 43A may transmit a content entity data request instruction to the mobile phone 1B. For example, in the content acquisition unit 43A, the authentication unit 36A may transmit authentication data and also transmit a content entity data request instruction to the mobile phone 1B.

[Modification 6]
When the authentication for canceling the restriction on the operation of the restricted content in the second display area is executed due to the difference in the version of the “communication application to be loaded” held by the cellular phone 1A and the cellular phone 1B, it is requested from the cellular phone 1B. There may be a case where the mobile phone 1A does not support the authentication method. In this case, the mobile phone 1A acquires the authentication execution information necessary for executing the requested authentication method from the mobile phone 1B, and executes the requested authentication method based on the acquired authentication execution information.

  Specifically, when the authentication unit 36A of the mobile phone 1A receives the authentication data request instruction from the mobile phone 1B, the own device holds the authentication execution information necessary for executing the authentication method indicated by the authentication data request instruction. Check if it is. When the own apparatus does not hold the authentication execution information necessary for executing the authentication method, the authentication unit 36A issues an authentication execution information request instruction for requesting the authentication execution information to the authentication unit 36B of the mobile phone 1B. Send.

  Upon receiving the authentication execution information request instruction from the mobile phone 1A, the authentication unit 36B of the mobile phone 1B reads predetermined authentication execution information from the storage unit 12B, and transmits the read authentication execution information to the mobile phone 1A.

  Upon receiving the authentication execution information as a response to the authentication execution information request instruction, the authentication unit 36A of the mobile phone 1A displays an authentication data input screen on the display control unit 32A based on the received authentication execution information. To instruct. The authentication unit 36A generates authentication data from the input signal acquired by the input operation specifying unit 33A based on the received authentication execution information.

  That is, the authentication execution information necessary for executing the authentication method is, for example, authentication data input screen generation information for the display control unit 32A to generate an authentication data input screen, or authentication data from an input signal from the user. It includes authentication data generation information for generation.

[Modification 7]
In the present embodiment, the multi-layer state is determined using the main display unit 13a and the sub display unit 13b, which are optical sensor liquid crystals, and communication is performed with Bluetooth. However, the determination method and the communication method are not limited thereto. is not. For example, another mobile phone 1 may be detected by a magnetic sensor, a pressure sensor, or the like. In the present invention, any method can be used as long as it can determine the state in which the two mobile phones 1 are overlapped, and if the two mobile phones 1 can communicate in the multi-layer state, Any communication method may be used.

  Other specific examples of the determination method and the communication method will be described in detail based on the following embodiments.

<Second Embodiment>
The following describes the second embodiment of the present invention with reference to FIGS.

In other words, the upper terminal state determination unit 41a determines whether or not there is another mobile phone 1a on the back side of the own device. In the present embodiment, the upper terminal state determination unit 41a determines whether or not the optical sensor 17c has detected predetermined light emitted from the display unit 13c, and the optical sensor 17c is irradiated from the display unit 13c. When the predetermined light is detected, the device is determined to be the upper terminal A. More specifically, the upper terminal state determination unit 41a determines whether or not the light sensor 17c detects predetermined light at a predetermined light receiving interval.

That is, the display control unit 32B causes the display unit 13cB to blink and display (S53).

  On the other hand, when the proximity sensor 18 does not detect a proximity object (NO in S51), the upper terminal state determination unit 41a determines whether or not the optical sensor 17c has detected blinking display on the display unit 13c (S54). When the optical sensor 17c detects blinking display (YES in S54), the upper terminal state determination unit 41a determines that the own device is the upper terminal A (S55). When the optical sensor 17c does not detect blinking display (NO in S54), the process returns to S51 again.

  In the processing example of FIG. 17, the multilayer state determination process is performed after the communication application to be loaded is activated, but the present invention is not limited to this. For example, when the proximity sensor 18 detects an object, the communication application to be placed is activated, the lower terminal state determination unit 42a determines that the own device is the lower terminal B, and the optical sensor 17c detects blinking display. At that time, the communication application to be placed may be activated, and the upper terminal state determination unit 41a may determine that the own device is the upper terminal A.

The multilayer state maintenance determination process of the present embodiment will be described in detail.

  In S6A, the upper terminal state determination unit 41aA continuously determines whether the optical sensor 17cA detects the blinking display of the display unit 13cB every predetermined period. If the optical sensor 17cA continuously detects blinking display, the upper terminal state determination unit 41aA determines that the multi-layer state is maintained (NO in S6A). On the other hand, when the optical sensor 17cA no longer detects the blinking display, the upper terminal state determination unit 41aA determines that the mobile phone 1aA has moved away from the mobile phone 1aB (YES in S6A), and ends the communication application carried by the control unit 11aA. (S7A).

  In S6B, lower terminal state determination unit 42aB continuously determines whether or not proximity sensor 18B detects an object for each predetermined period. If the proximity sensor 18B continuously detects the object, the lower terminal state determination unit 42aB determines that the multi-layer state is maintained (NO in S6B). On the other hand, when the proximity sensor 18B no longer detects an object, the lower terminal state determination unit 42aB determines that the mobile phone 1aB has moved away from the mobile phone 1aA (YES in S6B), and ends the communication application carried by the control unit 11aB ( S7B).

Here, on the surface of the extending portion 53, the surface on the multi-end side of the base portion 52 is referred to as an inner surface, and the surface on one end side of the base portion 52 is referred to as an outer surface.

  As shown in FIG. 30, the cellular phones 1eA and 1eB have a front side IR module 22a disposed on the inner side surface on the distal end side (front side) of the extending portion 53, and a rear side on the outer side surface on the bottom side of one end of the base portion 52. An IR module 22b is arranged.

  Thus, when the cross section of the side view of the mobile phone 1eA and 1eB is L-shaped, when the user puts the two mobile phones 1e into a multi-layered state, the two easily and accurately Mobile phone 1e can be stacked. Therefore, the two mobile phones 1e can be reduced from being overlapped with each other in the multi-layered state, so that the state in which the two mobile phones 1e cannot communicate in the multi-layered state can be reduced.
