ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a water sinking confirmation device and in particular, it relates to one to be used in a portable terminal device or the like, enabling judgment on whether or not the device has been sunk in water only by seeing a lower case.
2. Description of the Related Art
Conventionally, as a water sinking confirmation device to be used in a portable terminal device such as a portable phone device or a PHS, one shown in
FIG. 6
has been known. In
FIG. 6
, the water sinking confirmation device comprises an internal unit
61
with a water sinking confirmation seal
62
attached at a predetermined position, and a lower case
63
having a hole
64
formed at a predetermined position such that the water sinking confirmation seal
62
attached on the internal unit
61
is seen through a transparent sheet
65
, attached together.
However, since other parts of the portable terminal device are mounted on the hole
64
provided in the lower case
63
in the conventional water sinking confirmation device, it involves a problem in that the water sinking state of the water sinking confirmation seal
62
attached on the internal unit
61
cannot be seen directly through the hole
64
formed in the lower case
63
.
Moreover, since the water sinking confirmation seal
62
is attached directly on a predetermined position of the internal unit
61
and the transparent sheet
65
is bonded or adhered to the lower case
63
, surrounding the hole
64
, the water sinking confirmation seal
62
and the transparent sheet
65
are not sealed closely, and thus a problem is involved in that the water sinking confirmation seal
62
may generate the state change when it is not sunk in water.
SUMMARY OF THE INVENTION
In order to solve the above problems, an object of the invention is to provide a water sinking confirmation device enabling judgment on whether or not a portable terminal device or the like has been sunk in water only by seeing a lower case.
In order to achieve the above object, according to the invention, there is provided a water sinking confirmation device comprising: a lower case provided with a hole for confirming water sinking; a double side coated adhesive member for bonding both sides, surrounding the hole; a transparent sheet allowing a state change of a water sinking confirmation seal seen through from a surface thereof; and the water sinking confirmation seal including a double side coated adhesive member disposed at both ends of the transparent sheet and a white plain paper, and the white plain paper applied with red color printing with a water-color ink at a center thereof.
