Description

  The present invention relates to a submergence confirmation paper and a portable terminal used for recognizing a submergence history when the color changes due to moisture attached to water-sensitive equipment such as a portable terminal.

Conventionally, a portable terminal using a submergence confirmation sheet that can accurately recognize a submergence history has been proposed (see, for example, Patent Document 1).
In general, when submersion confirmation paper whose color changes with moisture is used for a portable terminal that is vulnerable to water, it is attached to an opening of an earphone attachment portion, an opening portion of a battery storage portion, or the like. For example, when installing the submergence confirmation paper in the battery compartment, make a notch such as a window on the inner wall of the battery compartment, and submerge the back of the window (the back side of the inner wall of the battery compartment, that is, the electronic device side). A confirmation sheet is attached so that it can be seen from the window. For this reason, the submergence confirmation paper is configured by attaching a transparent member such as PET to the front surface of the reaction paper and attaching double-sided tape or the like to both front edges of the PET or the like, and is attached to the back side of the window with the double-sided tape.
Japanese Patent Laid-Open No. 2004-146907 (FIG. 1)

  However, as described above, when the submersion confirmation paper is attached to the battery compartment, since it is attached from the back side of the window with double-sided tape, the installation work is performed outside the battery compartment, that is, in a narrow place on the electronic device side. There was a problem that workability was poor because the pasting work had to be performed in a state in which it was not visible.

  The present invention has been made to solve the conventional problems, and an object thereof is to provide a submerged confirmation paper and a portable terminal that can be easily attached to a predetermined position.

  The submerged confirmation paper of the present invention has a planar reaction part that changes color when water is immersed, a transparent protective part provided on one side of the reaction part, and the opposite side of the reaction part on the one side. And an adhesive part provided on the side surface, wherein at least one part of one side of the reaction part or the side opposite to the one side is exposed.

With this configuration, the reaction part is provided with a transparent protective part on the side viewed from the window or the like, and the adhesive part is provided on the reaction part on the opposite side of the protective part. Instead, it can be affixed in advance to a part of the other module, substrate, etc. housed in the housing that faces the window. For this reason, the pasting workability is improved and the pasting failure can be avoided.
And since at least one part of one or both surfaces of the reaction part is exposed, it can react to moisture immediately when it receives moisture intrusion.

  Furthermore, the submerged confirmation paper of the present invention is characterized in that a part of one side of the reaction part and a part of the surface opposite to the one side are exposed.

  With this configuration, the exposed portions are provided on both surfaces of the reaction portion, so that when moisture enters, it can immediately react to moisture. In addition, by providing an exposed part on one side where the transparent protective part is attached, it reacts quickly to the intrusion of moisture from one side, and at the time of the intrusion of moisture from the opposite side, Since it is easy to expel the contained air, it can react quickly.

  Furthermore, the portable terminal of the present invention is characterized in that the above-described submergence confirmation paper is used.

  The present invention can provide a submerged confirmation paper and a portable terminal capable of improving pasting workability and avoiding poor pasting.
