In addition, each connection frequency from 0:00 to 23:00 on each day of the week is based on the time measured by the timer 45 when the total value of the connection frequencies from 0:00 to 23:00 is 100%. The connection frequency percentage is shown.

  Returning to FIG. 4, the vibrator 47 is attached inside the operation unit side body 2 and generates vibrations under the control of the CPU 44. When the vibration generated by the vibrator 47 is transmitted to the operation unit side body 2, the mobile phone 1 vibrates.

  One or a plurality of the LEDs 48 are arranged at predetermined locations on the operation unit side body 2 and / or the display unit side body 3 so as to emit light based on the voltage supplied from the control of the CPU 44 and the power supply control circuit unit 51. It is configured.

The power supply control circuit unit 51 also supplies power to other electronic components and functional blocks.

  Next, the operation of the CPU 44 when the water wetting state is detected by the water wetting detecting unit 42 will be described. FIG. 6 is a schematic diagram illustrating the transition of the locked state of the connector cover portions 18a and 18b and the warning display displayed on the display unit 21 according to the wet state of the mobile phone 1.

  When the water wetness detection unit 42 detects that the vicinity of the opening 16 is in a wet state, and the determination unit 441 determines that the tilt angle is within a predetermined range, the control unit 442 The unit 19 is controlled to the restricted state.

  In step S63, the control unit 442 updates the connection frequency in the connection frequency table 461.

According to the mobile phone 1 of the present embodiment, the following effects can be obtained.
When the water wetness detection unit 42 detects that the vicinity of the opening 16 is in a wet state, the control unit 442 supplies power to the regulation unit 19 and controls the regulation unit 19 to the regulation state.

  For this reason, when the vicinity of the opening 16 is wet, the connector cover 18 is restricted by the restriction 19 and is not opened. Therefore, even when the user does not notice the wetness in the vicinity of the opening 16, the connector cover 18 is opened, and water can be prevented from entering the operation unit side body 2 from the opening 16. be able to.

  In addition, the mobile phone 1 according to the present embodiment includes an inclination angle detection unit 43 that detects an inclination angle of the operation unit side body 2 with respect to a predetermined reference direction, and the control unit 442 is wetted by the water wetness detection unit 42. When the state is detected and the tilt angle detection unit 43 detects a tilt angle within a predetermined range, power is supplied to the regulation unit 19 to control the regulation unit 19 to the regulation state.

  For this reason, when the vicinity of the opening portion 16 is in a wet state and the inclination angle of the opening portion 16 is within a predetermined range, the connector cover portion 18 is restricted by the restriction portion 19. Therefore, even when the user does not notice the wetness in the vicinity of the opening 16, the connector cover 18 is opened, and water can be prevented from entering the operation unit side body 2 from the opening 16. be able to. Furthermore, when the inclination angle of the opening 16 is outside a predetermined range (for example, vertically downward), it is considered that water does not enter from the opening 16, so that the user is not warned unnecessarily. Convenience can be improved.

  Further, according to the mobile phone 1 of the present embodiment, when the pressure detection unit 49 detects a pressure exceeding a predetermined threshold while the control unit 19 is controlling the control unit 19 to the control state, the notification unit To perform a predetermined notification.

  For this reason, when the pressure exceeding the predetermined threshold is applied to the connector cover portion 18 while the restricting portion 19 is controlled to the restricted state, the user can remove the connector cover portion 18 even though it is wet. It is determined that it is going to be opened, and a predetermined notification is made. Therefore, even when the user tries to open the connector cover portion 18 in spite of being wet, the user can be warned of the state and alert the user.

  Further, according to the mobile phone 1 of the present embodiment, the control unit 442 is configured such that the water wetting state is not detected by the water wetting detecting unit 42 when the restricting unit 19 is controlled to the restricted state, or predetermined water is used. In the case of a wet state, which is smaller than the wet state, the restricting unit 19 is controlled to be in a released state.

  For this reason, the cellular phone 1 assumes that water does not enter from the opening 16 when the opening 16 is no longer wet or when the opening 16 is in a wet state that is smaller than a predetermined wet state. Then, the restriction of the connector cover portion 18 by the restriction portion 19 is released. Therefore, when water does not enter through the opening 16, the connector cover 18 can be opened.

  Further, according to the mobile phone 1 of the present embodiment, the control unit 442 causes the water wetness detection unit 42 to make a state where one of the plurality of openings 16a and 15b is wet with water. When it is detected as a wet state, the connector cover portion 18 disposed corresponding to the opening is restricted by the restriction portion 19.

  For this reason, for example, when one of the openings 16a and 15b is wet, the cellular phone 1 restricts the connector cover portions 18a and 18b disposed in the openings 16a and 15b by the restriction portion 19. To do. Therefore, it is possible to detect individual water wetting in the openings 16a and 15b and more suitably prevent water from entering from the openings 16a and 15b.

  Further, according to the mobile phone 1 of the present embodiment, the control unit 442 is a time when the water wetness state is detected by the water wetness detection unit 42 and the time measured by the clocking unit 45 in the connection frequency table 461. When the connection frequency stored in association with the condition satisfies a predetermined condition, the notification unit performs notification in a predetermined manner.

  For this reason, the mobile phone 1 can display a warning in a predetermined manner when the connection frequency at the time measured by the time measuring unit 45 satisfies a predetermined condition. Therefore, when the connection frequency of the connector is high, the cellular phone 1 can more suitably prevent water from entering from the opening 16 by regulating the connector cover 18 by the regulating unit 19.

  As mentioned above, although embodiment of this invention was described, this invention is not restrict | limited to embodiment mentioned above, It can change suitably. For example, in the above-described embodiment, the restricting unit 19 is configured to operate by receiving power supply. However, the present invention is not limited to this, and the restricting unit 19 operates without receiving power supply. It may be.
