  Hereinafter, the usage application selection process of the portable information terminal 100 according to the present embodiment will be described with reference to the flowchart of FIG. In the following description, it is assumed that there are two types of usages that can be selected by the portable information terminal 100 of the present embodiment: private usage and business usage. As shown in FIGS. 1 and 2, the mobile information terminal 100 moves by connecting two SIM cards 221 and 222 to the first SIM connection unit 171 and the second SIM connection unit 172, respectively. The telephone communication (call) function in the body telephone communication network is realized. Note that the first telephone number or the like when the portable information terminal 100 is used for private use is specified by the SIM card 221 connected to the first SIM connection unit 171. It is assumed that the second telephone number or the like when used for the purpose is specified by the SIM card 222 connected to the second SIM connection unit 172.

  In this embodiment, the usage application selection process in the portable information terminal 100 is started by pressing the power key 130p or the home key 130h. That is, first, the main control unit 101 confirms whether the power key 130p is pressed in the power-off state or the sleep state, or the home key 130h is pressed during normal operation (S101). ).

  The power key 130p and the home key 130h are operation keys constituting the operation unit 130. The power key 130p is used to switch the power on / off when pressed for a long time, and to set / cancel the sleep mode when pressed briefly. And Further, the home key 130h has a function of displaying the home screen (basic screen) by ending the running application program when pressed during execution of various application programs. In this embodiment, the power key 130p and the home key 130h are arranged at positions as shown in FIG.

  In S101, when neither the pressing of the power key 130p nor the pressing of the home key 130h is confirmed, the main control unit 101 ends the process of the flowchart of FIG. 3 without performing the usage application selection process. On the other hand, when it is confirmed in S101 that either the power key 130p is pressed or the home key 130h is pressed, the main control unit 101 next checks the connection status of the SIM cards 221 and 222 of the portable information terminal 100. (S102).

  If the connection of the SIM cards 221 and 222 to the first SIM connection unit 171 and the second SIM connection unit 172 is not confirmed in S102, that is, the SIM card connected to the portable information terminal 100 is zero. In the case of sheets, the main control unit 101 terminates the process of the flowchart of FIG. 3 without performing the intended use selection process. In this case, at least the telephone communication (call) function is invalidated. On the other hand, in S102, when both the SIM cards 221 and 222 are confirmed to be connected to the first SIM connection unit 171 and the second SIM connection unit 172, that is, two SIM cards are installed in the portable information terminal 100. If it is connected, the main control unit 101 next performs a chassis posture confirmation process (S103).

  The chassis posture confirmation process is a process for confirming the attitude (orientation) of the chassis when the portable information terminal 100 is held. In the present embodiment, the holding posture (orientation) of the portable information terminal 100 when the power key 130p or the home key 130h is pressed is such that the home key 130h is located as shown in FIG. The short side end portion is in a posture (hereinafter referred to as posture A) closer to the ground surface than the short side end portion on the side where the video input unit 123 is located, or as shown in FIG. Confirmation is made whether the short side end on the side where the video input unit 123 is positioned is closer to the ground surface than the short side end on the side where the home key 130h is positioned (hereinafter referred to as posture B). I do.

  It is assumed that the casing of the portable information terminal 100 does not necessarily have to be kept vertical when performing the casing posture confirmation process. Further, the body posture confirmation processing is performed by detecting gravitational acceleration by the acceleration sensor 161. The frame posture confirmation process may be performed using tilt detection using the gyro sensor 162, or may be performed using other sensors.

  Next, the main control unit 101 determines whether the first SIM connection unit 171 to which the SIM card 221 is connected or the second SIM connection unit 172 to which the SIM card 222 is connected according to the result of the body posture confirmation process in S103. A process of selecting and validating any one of these is performed (S104).

  Specifically, in the chassis posture confirmation process of S103, when it is confirmed that the chassis of the portable information terminal 100 is in the posture A state, the main control unit 101 performs the first SIM connection to which the SIM card 221 is connected. Section 171 is selected and activated. With the above-described processing, when using the telephone communication (call) function of the portable information terminal 100, the first telephone number specified by the SIM card 221 connected to the first SIM connection unit 171 is Can be used. At the same time, the main control unit 101 enables the first audio output unit 126a and the first audio input unit 128a shown in FIG. 4, and disables the second audio output unit 126b and the second audio input unit 128b. Turn into.

  On the other hand, when it is confirmed in the housing posture confirmation process of S103 that the housing of the portable information terminal 100 is in the posture B state, the main control unit 101 uses the second SIM connection unit 172 to which the SIM card 222 is connected. Select to activate. With the above-described processing, when using the telephone communication (call) function of the portable information terminal 100, the second telephone number specified by the SIM card 222 connected to the second SIM connection unit 172 is Can be used. At the same time, the main control unit 101 enables the second audio output unit 126b and the second audio input unit 128b shown in FIG. 4, and disables the first audio output unit 126a and the first audio input unit 128a. Turn into.

  That is, the portable information terminal 100 according to the present embodiment uses the portable information terminal 100 for private use assigned with the first telephone number by determining the posture (orientation) of the housing, or It is possible to easily select whether to use for business purposes to which a second telephone number is assigned.

  Further, the main control unit 101 performs a process of controlling access to each storage area of the storage unit 110 according to the result of the chassis posture confirmation process of S103 (S106).

  Specifically, when it is confirmed that the housing of the portable information terminal 100 is in the posture A state in S103, and the first SIM connection unit 171 to which the SIM card 221 is connected is activated in S104 (that is, mobile phone) When the information terminal 100 is used for private use), the main control unit 101 further performs processing for invalidating access to the second use storage area 112. In this case, for example, when the telephone communication (call) function of the portable information terminal 100 is used, the telephone book stored in the first use storage area 111 can be used, but the second The phone book stored in the use storage area 112 becomes unusable. In addition, information such as a call history (outgoing / incoming history) is stored in the first use storage area 111.

  On the other hand, when the housing of the portable information terminal 100 is confirmed to be in the posture B state in S103 and the second SIM connection unit 172 connected to the SIM card 222 is activated in S104 (that is, the portable information terminal 100 The main control unit 101 further performs a process of invalidating access to the first usage storage area 111. In this case, for example, when the telephone communication (call) function of the portable information terminal 100 is used, the phone book stored in the second use storage area 112 can be used. The phone book stored in the use storage area 111 becomes unusable. In addition, information such as a call history (outgoing / incoming history) is stored in the second use storage area 112.

  Note that the portable information terminal 100 according to the present embodiment is stored in the ROM 103 or the other storage area 113 of the storage unit 110 regardless of whether the portable information terminal 100 is used for private use or business use. It is assumed that all the functions (application programs) that can be used can be used. However, in any case where any function of the portable information terminal 100 is used, as described above, when the private use is selected as the use purpose of the portable information terminal 100, the second use storage area 112 is used. The access to the first use storage area 111 is basically invalidated when the business use is selected, and the access to the first use storage area 111 is basically invalidated.

  That is, for example, when using the mail function of the portable information terminal 100, the mail account information of the first mail address acquired for private use is stored in the first use storage area 111. . The address book stored in the first use storage area 111 can be used, but the address book stored in the second use storage area 112 cannot be used. Information such as mail transmission / reception history is stored in the first use storage area 111. On the other hand, the mail account information and the like of the second mail address acquired for use in business use is stored in the second use storage area 112. Further, the address book stored in the second use storage area 112 can be used, but the address book stored in the first use storage area 111 cannot be used. Information such as mail transmission / reception history is stored in the second use storage area 112.

  Further, for example, when using the web browsing function of the portable information terminal 100, downloading and uploading of data to a web page browsed for private use is performed on the first use storage area 111. The second storage area 112 is not used. On the other hand, downloading and uploading of data to a web page browsed for business use is performed for the second use storage area 112 but not for the first use storage area 111.

  As described above, by changing the access control to the first use storage area 111 and the second use storage area 112 in S106 according to the result of the body posture confirmation processing in S103, for example, for business use It is possible to prevent mistakes such as sending an e-mail to an e-mail address for private use. In addition, for example, it is possible to prevent a security accident such that a computer virus that has been infected when the portable information terminal 100 is used for private use is spread to an in-house network due to use for business use.

  When a new application program that can be shared for both private use and business use, such as a text editor, is downloaded from the application server 211 on the Internet 201, the new application program is stored in the other storage area 113. You may do it. It is assumed that the other information storage area 113 is accessible in both cases where the portable information terminal 100 is used for private use and for business use. However, also in the above-described case, the personal file created by the new application program is stored in the first use storage area 111 when the portable information terminal 100 is used for private use. When used in the second storage area 112, it is stored in the second use storage area 112.

  Further, in the process of S102 in the flowchart of FIG. 3, when only one of the SIM cards 221 and 222 connected to the first SIM connection unit 171 and the second SIM connection unit 172 is confirmed, that is, mobile phone When only one SIM card is connected to the information terminal 100, the main control unit 101 activates the SIM connection unit on the side where the connection of the SIM card is confirmed without performing the chassis posture confirmation process. (S105). At the same time, when the SIM connection unit on the side where the connection of the SIM card is confirmed is the first SIM connection unit 171, the access to the second usage storage area 112 is invalidated, and the SIM card If the SIM connection unit on which the connection has been confirmed is the second SIM connection unit 172, an access control process is performed to invalidate access to the first usage storage area 111 (S106). Just do it.

  As described above, the portable information terminal 100 according to the present embodiment can easily select the usage purpose by performing the series of processes shown in the flowchart of FIG. The operation can be performed reliably. In addition, it goes without saying that all functions of the portable information terminal 100 can be used in the same procedure regardless of whether the portable information terminal 100 is used for private use or business use. Therefore, it is possible to eliminate the inconvenience of carrying and using both a portable information terminal for private use and a portable information terminal for business use.

  In the above description, the usage applications that can be selected by the portable information terminal 100 of the present embodiment have been described as being of two types: private usage and business usage. However, this is merely an example, and the selection target may be two types, such as a first private use and a second private use. In this case, the first private use may be used for contact with the friend group A, and the second private use may be used for contact with the friend group B. In the first private use, all the functions of the portable information terminal 100 are set to be fully usable. On the other hand, in the second private use, a predetermined restriction (for example, web browsing) A difference may be provided in the setting conditions at the time of use, such as setting with a restriction or the like. Further, the difference in the setting conditions may be, for example, such that only the mail address to be used is changed between the first private use and the second private use.

  Further, the number of usage applications to be selected need not be two types as described above, and may be four types, for example. In this case, in the chassis posture confirmation process, in addition to the postures shown in FIGS. 5A and 5B, the long side on the side where the video input unit 123 is located as shown in FIG. The posture in which the end portion is closer to the ground surface than the long side end portion on the side where the home key 130h is located, and the long side end portion on the side where the home key 130h is located as shown in FIG. What is necessary is just to further discriminate | determine the attitude | position close | similar to the ground surface rather than the long side edge part by the side in which the image | video input part 123 is located. In this case, a third usage storage area and a fourth usage storage area are further prepared in the storage unit 110, and access to each storage area of the storage unit 110 is made according to the result of the chassis posture confirmation processing. It suffices to perform processing for controlling the above.

  In the above description, the usage application selection process of the portable information terminal 100 has been described as being started by pressing a predetermined operation key (in this embodiment, the power key 130p or the home key 130h). However, this is merely an example, and it may be started by a touch operation on an arbitrary position of the touch panel 130t. Further, for example, the body posture confirmation process is always performed, and when it is detected that the body posture of the portable information terminal 100 is in the state shown in FIG. 5A or FIG. Selection and control of access to each storage area may be executed.

  However, in this case, the posture of the casing of the portable information terminal 100 is changed to that shown in FIGS. 5A and 5B in order to prevent the usage application from being changed without the intention of the user of the portable information terminal 100. Even in the state shown in (2), it is desirable not to execute the selection of the intended use when the duration of the state is less than a predetermined value. Alternatively, whether or not the use application may be selected when it is detected that the posture of the casing of the portable information terminal 100 is in the state shown in FIG. 5A or FIG. It is desirable to display a screen for confirming the user's intention on the display unit 121 to confirm the intention of the user of the portable information terminal 100. Or you may set so that the selection process of the said usage may not be performed during operation | movement of a predetermined function (application).

  Further, for example, it may be an embodiment in which the user sets from the setting screen whether or not to activate any one of the SIMs depending on the posture of the casing of the portable information terminal 100. In this case, if the user turns on “automatic switching of SIM by posture” from the menu on the setting screen, the SIM is automatically switched to enable any SIM depending on the posture of the casing of the portable information terminal 100.
