Abstract

A portable wireless communication device includes a case having a waterproof structure and floating on water, an operation portion arranged in a front face of the case; and a wireless communication processing portion arranged inside the case, wherein a position of the center of gravity in the case is shifted to a rear face side opposite to the front face with respect to a center of the case, in a state where all components including the wireless communication processing portion are housed.

Claims

1. A portable wireless communication device comprising:

a case having a waterproof structure and floating on water;

an operation portion arranged in a front face of the case; and

a wireless communication processing portion arranged inside the case,

wherein a position of the center of gravity in the case is shifted to a rear face side opposite to the front face with respect to a center of the case, in a state where all components including the wireless communication processing portion are housed.

2. The portable wireless communication device according to claim 1, further comprising a display portion arranged in the front face of the case.

3. The portable wireless communication device according to claim 1, further comprising an antenna connected to the wireless communication processing portion,

wherein the antenna is placed upper than a water surface when the case floats on water.

4. The portable wireless communication device according to claim 1, wherein the rear face side of the case is thicker than the front face side, whereby the position of the center of gravity in the case is shifted to the rear face side with respect to the center of the case.

5. The portable wireless communication device according to claim 1, wherein the case includes an internal case housing the operation portion and the wireless communication processing portion, and an external case housing the internal case and having a waterproof structure.

9. The portable wireless communication device according to claim 1, further comprising a vibrator notifying of an incoming call or receipt of a message in wireless communication by vibrating the case,

wherein the control portion enables the vibrator to be vibrated in a state different from that in the normal mode when the underwater mode or the on-water mode is set.

10. The portable wireless communication device according to claim 9, wherein predetermined ripples are generated on water by the vibration of the vibrator in the underwater mode or the on-water mode.

11. The portable wireless communication device according to claim 9, wherein convex portions or concave portions are continuously arranged on a predetermined face of the case, and

wherein the case floating on water is rotated or progressed in a predetermined direction by vibrating the vibrator in the underwater mode or the on-water mode, in a state where the face with the convex portions or the concave portions is towards underwater.

6. A portable wireless communication device comprising:

a case having a waterproof structure;

a wireless communication processing portion arranged inside the case; and

a control portion setting operation modes of the device to a mode selected of a normal mode and an underwater mode or an on-water mode.

7. The portable wireless communication device according to claim 6, further comprising a sensor arranged in the case and detecting if the case is under water or on water,

wherein the control portion sets the underwater mode or the on-water mode when the sensor has detected that the case is under water or on water, and the control portion sets the normal mode when the sensor has not detected that the case is under water or on water.

8. The portable wireless communication device according to claim 6, wherein the control portion outputs a ring alert, which notifies of an incoming call or receipt of a message in wireless communication, in a state different from that in the normal mode when the underwater mode or on-water mode is set.

12. The portable wireless communication device according to claim 6, further comprising an illumination portion illuminating a predetermined position of the case,

wherein the control portion changes an illumination state in the normal mode and an illumination state in the underwater mode or the on-water mode.
