  Hereinafter, the configuration of the mobile terminal 100 according to an embodiment of the present invention will be described with reference to FIGS.

  The mobile terminal 100 according to an embodiment of the present invention is configured to be compatible with three modes: a business mode, an after 5 mode, and a holiday mode. The mobile terminal 100 includes a case 1 and a main body 2 as shown in FIG. The case 1 is configured to be attachable so as to cover the main body 2. There are a plurality of cases 1 that can be used for the portable terminal 100, for example, a case 1a for the after 5 and a case 1b for the holidays. The case 1 is an example of the “magnetic member installation member” in the present invention. The case 1a for the after 5 is an example of the “magnetic member installation member” and “case” of the present invention. The holiday case 1b is an example of the “magnetic member installation member” and “case” of the present invention. The main body 2 is an example of the “main body portion” in the present invention. The business mode, the after-five mode, and the holiday mode are examples of the “operation mode” of the present invention.

  Here, in the present embodiment, as shown in FIG. 2, the main body 2 includes a substrate 21 (see FIG. 3) on which electronic components are mounted, a power supply unit 22 that supplies power to the electronic components provided in the main body 2, A communication unit 23 capable of telephone communication and Internet communication, a touch panel 24 capable of performing a touch operation, and a storage unit 25 that stores data are included. The main body 2 includes a geomagnetic sensor 26 that can detect geomagnetism and magnetism, and a control unit 27 that controls the mobile terminal 100. The touch panel 24 is an example of the “display unit” in the present invention. The geomagnetic sensor 26 is an example of the “magnetic sensor” in the present invention.

  Moreover, the case 1 contains the permanent magnet 11 as shown in FIGS. Further, the case 1 is provided with a recess 12 in which a substantially cubic permanent magnet 11 is disposed. The permanent magnet 11 is fixed to the recess 12 with an adhesive member such as a tape. The permanent magnet 11 is provided in the case 1 so as to face the geomagnetic sensor 26 when the case 1 is attached to the main body 2. The permanent magnet 11 is configured to generate a magnetic field detectable by the geomagnetic sensor 26 from the north pole to the south pole. The permanent magnet 11 is an example of the “magnetic body” in the present invention.

  The case 1a for the after 5 is attached to the main body 2 when switching to the after 5 mode. The holiday case 1b is attached to the main body 2 when switching to the holiday mode. Moreover, the case 1a for the after 5 and the case 1b for holidays are configured so that the magnetic fields generated from the permanent magnets 11a and 11b can be distinguished from each other. The permanent magnet 11a is an example of the “magnetic body” in the present invention. The permanent magnet 11b is an example of the “magnetic body” in the present invention.

  Specifically, as shown in FIG. 4, the case 1 a for the after 5 is configured such that the surface including the N pole of the permanent magnet 11 a is disposed on the Z1 direction side. Thereby, when the case 1a for the after 5 is attached to the main body 2, a magnetic field is generated from the permanent magnet 11a side toward the main body 2 side (Z1 direction). Further, as shown in FIG. 5, the holiday case 1b is configured such that the surface including the N pole of the permanent magnet 11b is arranged on the Z2 direction side. Thereby, when the case 1b for holidays is attached to the main body 2, it is generated from the permanent magnet 11b. The direction of the magnetic field generated from the permanent magnet 11b is opposite to the direction of the permanent magnet 11a of the case 1a for the after 5.

  As shown in FIG. 3, the substrate 21 is provided inside the main body 2. As shown in FIGS. 9 to 14, the touch panel 24 is configured to be able to display predetermined information such as a standby screen and a telephone book set by the user.

  The storage unit 25 is configured by a rewritable nonvolatile memory. The storage unit 25 is configured to be able to store data related to the phone book registered by the user and the application of the mobile terminal 100.

  As shown in FIGS. 3 to 5, the geomagnetic sensor 26 is provided on the surface of the substrate 21 on the Z2 direction side. The geomagnetic sensor 26 is configured to detect geomagnetism. Further, the geomagnetic sensor 26 is used as an electronic compass capable of identifying the direction from the geomagnetism detected by the mobile terminal 100. The geomagnetism is generated along the horizontal direction (X direction and Z direction) from the vicinity of the south pole of the earth to the vicinity of the north pole. Further, the geomagnetism is not substantially generated in the vertical direction (Y direction). Further, the geomagnetic sensor 26 is configured to be able to detect a magnetic field generated from the permanent magnet 11. The geomagnetic sensor 26 is also configured to detect the magnetic field of the permanent magnet 11 provided in the case 1. Note that the geomagnetic sensor 26 may be provided on the surface of the substrate 21 on the Z1 direction side as long as there is no obstacle between the geomagnetic sensor 26 and the permanent magnet 11.

  Next, the waveform of the magnetic field detected by the geomagnetic sensor 26 when the mobile terminal 100 is rotated 360 degrees about the rotation axis R shown in FIG. 1 will be described. First, in the Z direction (horizontal direction), in a state where the case 1 is not attached to the main body 2, as shown in FIG. 6, geomagnetism is detected (waveform A). Further, in the state where the case 1a for the after 5 (see FIG. 4) is attached to the main body 2, the geomagnetism is detected with the Z0 offset in the positive direction due to the influence of the magnetic field by the permanent magnet 11a in the Z direction ( Waveform B). That is, it is detected in a state where the magnetic field by the geomagnetism and the magnetic field by the permanent magnet 11a are superimposed. Further, in the state where the holiday case 1b (see FIG. 5) is attached to the main body 2, the geomagnetism is detected in a state where the Z direction is Z0 offset in the negative direction due to the influence of the magnetic field by the permanent magnet 11b. C). That is, it is detected in a state where the magnetic field by the geomagnetism and the magnetic field by the permanent magnet 11b are superimposed.

  Further, in the vicinity of the geomagnetic sensor 26 with the case 5a for the after 5 and the holiday case 1b attached, the magnetic field directed in the X1 direction and the magnetic field directed in the X2 direction cancel each other in the X direction (horizontal direction). There is no magnetic field effect. For this reason, in the X direction, as shown in FIG. 7, the waveform of the magnetic field is obtained when the case 1 is not provided, when the case 1a for the after 5 is attached, and when the case 1b for holidays is attached. There is virtually no difference.

  Further, in the vicinity of the geomagnetic sensor 26 with the case 5a for the after 5 and the case 1b for holidays attached, the magnetic field in the Y1 direction and the magnetic field in the Y2 direction cancel each other in the Y direction (vertical direction). There is no magnetic field effect. Further, the geomagnetism is not substantially detected in the Y direction. For this reason, in the Y direction, as shown in FIG. 8, the waveform of the magnetic field is obtained when the case 1 is not provided, when the case 1a for the after 5 is attached, and when the case 1b for holidays is attached. There is virtually no difference.

  Further, in the mobile terminal 100 of the present embodiment, the calibration operation of the geomagnetic sensor 26 is performed by the user in order to correct the geomagnetic detection error caused by the magnetism different from the geomagnetism. Specifically, the mobile terminal 100 is rotated by the user 360 degrees with the rotation axis R (see FIG. 1) as the rotation axis R (see FIG. 1), which is the approximate center of the mobile terminal 100 in the X direction and along the Y direction. In the Z direction, the magnetic field strength from 0 degrees to 360 degrees (see FIG. 6) is continuously detected. Then, for example, an accurate offset value is calculated by averaging the intensity of the magnetic field detected every time. In addition, as long as the portable terminal 100 is an axis along the Y direction, the portable terminal 100 may rotate about an axis other than the rotation axis R passing through the approximate center of the portable terminal 100 in the X direction.

  Further, in the X direction and the Y direction, although there is no influence of the magnetic field by the permanent magnets 11a and 11b, the magnetic field generated from the electronic component of the mobile terminal 100 can be detected. For this reason, the same calibration operation as that in the Z direction is performed in the X direction and the Y direction.

  Further, as shown in FIG. 6, the magnetism of the permanent magnet 11 is greater than the Zn whose magnitude of the offset value (Z0, -Z0) with respect to the geomagnetism of the permanent magnet 11 is the difference between the maximum value and the minimum value of the geomagnetism intensity. Is configured to be larger. In addition, data related to the geomagnetism detected by the geomagnetic sensor 26 and the magnetism generated from the permanent magnet 11 is output to the control unit 27.

  The control unit 27 is configured to be able to acquire data relating to the geomagnetism detected by the geomagnetic sensor 26 output from the geomagnetic sensor 26 and the magnetism generated from the permanent magnet 11. Further, the control unit 27 detects the case 1a for the after 5 and the holiday 1b based on the detection of the case 1a for the after 5 including the permanent magnet 11a and the case 1b for the holiday including the permanent magnet 11b by the geomagnetic sensor 26. The case 1b for use is identified. The control unit 27 is configured to perform control to determine that the case 1 is not attached when the geomagnetic sensor 26 does not detect the case 1a for the after 5 and the case 1b for holiday. Based on the magnetic fields generated by the permanent magnets 11a and 11b of the after-case 5a and the holiday case 1b detected by the geomagnetic sensor 26, the control unit 27 performs the after-case 5a and the holiday case. It is configured to identify 1b. Specifically, the control unit 27 is configured to identify the case 1a for the after 5 and the case 1b for the holiday based on the direction and magnitude of the magnetic field of each of the permanent magnets 11a and 11b.

  The control unit 27 is configured to calculate an offset value as a detection error for the geomagnetism of the permanent magnet 11 as magnetism corresponding to the permanent magnet 11. Further, the control unit 27 is configured to identify the case 1a for the after 5 and the case 1b for the holiday based on the magnitude and direction of the calculated offset value. Then, the control unit 27 identifies the after 5 mode corresponding to each of the identified case 1a for the after 5 or the case 1b for the holiday based on the fact that the case 1a for the after 5 and the case 1b for the holiday are identified. It is configured to perform control to switch to the holiday mode. The control unit 27 is configured to perform control to switch to the business mode when the case 1 is not attached.

  In the business mode, the control unit 27 is configured to display an icon 28a of an application suitable for business (for example, an application for editing text) on the touch panel 24, as shown in FIG. Further, as shown in FIG. 10, the control unit 27 is configured to display a telephone book 28 b suitable for business on the touch panel 24.

  In the after 5 mode, as shown in FIG. 11, the control unit 27 performs control to switch the icon 29 a of an application suitable for the after 5 (for example, an application that provides restaurant information) so that the icon 29 a can be displayed on the touch panel 24. Is configured to do. In the after 5 mode, the control unit 27 is configured to perform control to switch the telephone directory 29b suitable for the after 5 so that it can be displayed on the touch panel 24, as shown in FIG.

  In the holiday mode, the control unit 27 performs control to switch the icon 30a of an application suitable for a holiday (for example, an application that provides shopping information) so that the touch panel 24 can be displayed as shown in FIG. It is configured. Further, as shown in FIG. 14, the control unit 27 is configured to perform control so that the telephone book 30 b suitable for holidays can be displayed on the touch panel 24 in the holiday mode.

  The control unit 27 is configured to perform control for calculating an offset value of the permanent magnet 11 with respect to the geomagnetism when the user performs a calibration operation of the geomagnetic sensor 26 to correct the geomagnetic detection error. Thereby, it is possible to identify the case 1 without impairing the function of the geomagnetic sensor 26 as an electronic compass. In addition, the control unit 27 performs control for switching the display of the touch panel 24 so that an interface screen corresponding to the after 5 mode or the holiday mode corresponding to each of the detected case 1a for the after 5 or the holiday case 1b is obtained. Configured to do. Further, the control unit 27 is configured to perform control to switch the display of the touch panel 24 so as to obtain an interface screen corresponding to the business mode.

  Next, with reference to FIG. 15, an operation mode switching process flow by the control unit 27 of the mobile terminal 100 of the present embodiment will be described.

  First, in step S <b> 1, data on the X direction, Y direction, and Z direction magnetism generated from the geomagnetism and the permanent magnet 11 is acquired from the geomagnetic sensor 26. When data about the magnetism generated from the geomagnetism and the permanent magnet 11 is acquired, the process proceeds to step S2.

  In step S2, offset values in the X, Y, and Z directions with respect to the geomagnetism of the permanent magnet 11 are calculated. At this time, as shown in FIG. 1, the mobile terminal 100 is rotated by the user about the axis of the mobile terminal 100 in the X direction and along the Y direction as the rotation axis R.

  Next, in step S3, the case 1 is identified based on the calculated offset value for the geomagnetism of the permanent magnet 11. When the case 1 attached to the main body 2 is identified as the case 1a for the after-sales 5, the process proceeds to step S4. At this time, the case 1a for the after 5 is identified based on the fact that the offset value in the Z direction is calculated as approximately Z0. If the case 1 attached to the main body 2 is identified as the holiday case 1b, the process proceeds to step S5. At this time, based on the fact that the offset value in the Z direction is calculated as approximately −Z0, the case 1b for holidays is identified. If it is determined that the case 5a for the after 5 or the case 1b for holidays is not attached to the main body 2, the process proceeds to step S6. At this time, based on the fact that the offset value in the Z direction is calculated to be approximately 0, it is identified that the case 1 is not attached.

  In step S4, the mode is switched to the after 5 mode. When the mode is switched to the after 5 mode, an application icon 29a (see FIG. 11) suitable for the after 5 is displayed on the touch panel 24 as a standby screen for the after 5. In addition, a telephone directory 29b (see FIG. 12) suitable for the after 5 is set so that it can be displayed on the touch panel 24. Thereafter, the operation mode switching process flow is terminated.

  In step S5, the mode is switched to the holiday mode. When the mode is switched to the holiday mode, an application icon 30a (see FIG. 13) suitable for holidays is displayed on the touch panel 24 as a holiday standby screen. In addition, a telephone directory 30b (see FIG. 14) suitable for holidays is set so that it can be displayed on the touch panel 24. Thereafter, the operation mode switching process flow is terminated.

  In step S6, the mode is switched to the business mode or the mode is not switched. Specifically, when the case 1 is removed from the main body 2, the mode is switched to the business mode. When the business mode is already set, the business mode is continued without switching the mode. When switched to the business mode, an application icon 28a (see FIG. 9) suitable for business is displayed on the touch panel 24 as a standby screen for business. Further, the telephone book 28b (see FIG. 10) suitable for business is set so that it can be displayed on the touch panel 24. Thereafter, the operation mode switching process flow is terminated.

  In the present embodiment, as described above, the detected case 1 among the plurality of cases 1 is identified based on the detection of the case 1 including the permanent magnet 11 by the geomagnetic sensor 26, and the identified case 1 A control unit 27 that performs control to switch to the corresponding operation mode is provided. Accordingly, the user automatically selects the case 1 corresponding to the desired operation mode from among the plurality of cases 1 according to the situation and attaches it to the main body 2, and automatically enters the operation mode corresponding to the case 1 after attachment.
