  The graph shown in FIG. 3 represents the output logic characteristic with respect to the magnetic flux density detected by the Hall element for detecting the S pole. Note that the predetermined value Brps is smaller than the predetermined value Bops.

  Here, in the magnetic sensor 10 using this Hall element, the output logic value of the magnetic sensor 10 when the magnetic flux density shifts from the N pole to the S pole will be described. When the magnetic field on the N pole side is being applied and the magnetic sensor 10 detects the magnetic flux density on the N pole side, the output logical value of the magnetic sensor 10 is 1. Even when the magnetic sensor 10 does not detect the magnetic flux density, the output logic value of the magnetic sensor 10 is 1, and from the state where the magnetic flux density is not detected, the magnetic flux density on the S pole side is less than the predetermined value Bops. Until this state, the output logic value of the magnetic sensor 10 is 1. Further, when the magnetic sensor 10 detects that the magnetic flux density on the S pole side is equal to or higher than the predetermined value Bops, the output logical value of the magnetic sensor 10 becomes zero.

  Next, the output logic value of the magnetic sensor 10 when the magnetic flux density shifts from the S pole to the N pole will be described. When the magnetic sensor 10 detects that the magnetic flux density on the S pole side is equal to or higher than the predetermined value Bops, the output logical value of the magnetic sensor 10 is zero.

When the magnetic field on the S pole side is being applied and the magnetic sensor 10 detects the magnetic flux density on the S pole side, the output logical value of the magnetic sensor 10 is 1. Even when the magnetic sensor 10 does not detect the magnetic flux density, the output logic value of the magnetic sensor 10 is 1, and from the state where the magnetic flux density is not detected, the magnetic flux density on the N pole side is detected to be less than the predetermined value Boppn. Until this state, the output logic value of the magnetic sensor 10 is 1. Further, when the magnetic sensor 10 detects that the magnetic flux density on the N pole side is equal to or higher than the predetermined value Bpn, the output logical value of the magnetic sensor 10 is zero.

  Next, the output logic value of the magnetic sensor 10 when the magnetic flux density shifts from the N pole to the S pole will be described. When the magnetic sensor 10 detects that the magnetic flux density on the N pole side is equal to or greater than the predetermined value Bopp, the output logical value of the magnetic sensor 10 is zero. The output logic value of the magnetic sensor 10 is 0 from the state of the predetermined value Bopn or more to the state where the magnetic flux density on the N pole side exceeds the predetermined value Brpn. Further, when the magnetic sensor 10 detects that the magnetic flux density on the S pole side is equal to or less than the predetermined value Bpn, the output logical value of the magnetic sensor 10 is 1.

  The portable terminal 20 treats the output logical values output to the N pole detection output terminal and the S pole detection output terminal of the magnetic sensor 10 as signals. For example, when the magnetic sensor 10 does not detect a magnetic field, the output logical values output to the N pole detection output terminal and the S pole detection output terminal are both 1, so that the signal is “11” when expressed in 2 bits. . When the magnetic sensor 10 detects the south pole, the output logic values output to the north pole detection output terminal and the south pole detection output terminal are 1 and 0, respectively. Become. Further, when the magnetic sensor 10 detects the N pole, the output logic values output to the N pole detection output terminal and the S pole detection output terminal are 0 and 1, respectively, so that the signal is “01”. Become. Thus, three states are specified from the 2-bit signal output from the magnetic sensor 10.

As shown in FIG. 6, in the usage pattern 3, the magnetic sensor 10a and the magnetic body 9a are close to each other, the magnetic sensor 10a detects the south pole, and the magnetic sensor 10b does not detect the magnetic field, so the signal is “1011”. It becomes. In the usage mode 8 shown in FIG. 1, the magnetic sensor 10a detects the N pole and the magnetic sensor 10b does not detect the magnetic field, so the signal is “0111”.

More specifically, the image is rotated and displayed on the screen 14 around an orthogonal line orthogonal to the screen 14 and passing through the center of the screen 14 according to the detected usage.

  For example, when the user changes from the usage pattern 2 shown in FIG. 1 to the usage pattern 3 while the screen 14 is displaying an image, the CPU of the portable terminal 20 is used from the usage pattern 2 in FIG. As shown in the third embodiment, the orientation and size of the image are changed, and the changed image is displayed on the screen 14.
