The chamfered portion is in contact with the corner of the double-sided tape,
The double-sided tape is configured to peel from the corner when the tag is pulled.

  According to said structure, when peeling a sheet | seat with a tag, since the four corners of the opening for double-sided tape are contacting the corner | angular part of a double-sided tape, a double-sided tape peels easily from a corner | angular part. For this reason, the peeling operation of the rechargeable battery becomes extremely easy.

  As described above, according to the present invention, the rechargeable battery attached to the cabinet can be easily and safely removed by sandwiching the tagged sheet between the front surface of the rechargeable battery and the back surface of the cabinet.

FIG. 3 is an enlarged cross-sectional view taken along line II in FIG. 2. It is a front view which shows a mobile telephone. It is the perspective view which looked at the mobile telephone which removed the rear cover and the back side cabinet from the back side. FIG. 4 is a view corresponding to FIG. 3 with the rechargeable battery removed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show a mobile phone 1 as a mobile terminal according to an embodiment of the present invention. The mobile phone 1 has a display unit 2 (not shown in FIG. 2) including a liquid crystal display, an organic EL display, etc. on the front side. The front cabinet 3 is housed in the cabinet. A back side cabinet 4 is provided on the back side of the front side cabinet 3, and the back side is covered with a rear cover 5.

  In the front cabinet 3, for example, a metal frame 6 made of a sheet metal such as a stainless steel plate is insert-molded at the center. The metal frame 6 may be a metal molded product made of magnesium alloy, aluminum alloy or the like.

  As shown in FIG. 3, the rechargeable battery 7 is attached to the back surface of the metal frame 6. Specifically, as shown in FIG. 4, a pair of double-sided tapes 8 are attached to the metal frame 6 so as to extend in the vertical direction with a predetermined interval in the width direction. And the sheet | seat 9 with a tag is inserted | pinched between the rechargeable battery 7 front surface and the metal frame 6 back surface so that these double-sided tapes 8 may be avoided. Thus, the front surface of the rechargeable battery 7 is bonded to the metal frame 6 by the double-sided tape 8.

  Specifically, the tag-attached sheet 9 is formed with a pair of double-sided tape openings 10 so as to avoid the double-sided tape 8. This double-sided tape opening 10 has a rectangular shape, and its four corners are not chamfered at right angles, but chamfers 11 are formed so that a sheet with a tag remains in a triangular shape. The chamfered portion 11 is connected to the corner of the double-sided tape 8. When the connected portion is pulled, the double-sided tape 8 is torn and the double-sided tape 8 is easily peeled off.

  As shown in FIG. 3, the tag 12 of the tagged sheet 9 is exposed on the left side when viewed from the back, for example. Note that the tag 12 may be exposed from the right side, the upper side, or the lower side.

  When recycling the mobile phone 1 configured in this way, first, the rear cover 5, the back side cabinet 4 and the like are removed.

  Next, the exposed tag 12 is pulled as shown in FIG.

  Then, the rechargeable battery 7 is smoothly peeled from the metal frame 6 so that the sheet 9 with a tag gradually lifts the rechargeable battery 7 from the left side when viewed from the back. At this time, since the corner portion of the double-sided tape 8 is pulled from the upper or lower chamfer 11 and is torn, the double-sided tape 8 is easily peeled off.

  Next, the left double-sided tape 8 is peeled off, and the right double-sided tape 8 is similarly peeled off.

  Thereby, the rechargeable battery 7 can be easily peeled off without being damaged by trying to forcibly peel it off.

  Thus, by providing the opening 9 for double-sided tapes in the sheet 9 with a tag, and covering other than the part with the double-sided tape 8 with the sheet 9 with a tag, the area | region of the sheet 9 with a tag is increased as much as possible, and the rechargeable battery 7 is used. It can be easily peeled off.

  Therefore, according to the portable terminal according to this embodiment, the rechargeable battery 7 can be easily and safely recycled because the rechargeable battery 7 is surely peeled off from the metal frame 6 by pulling the tagged sheet 9. it can.
