Abstract

The portable information device includes: a display whose back surface is supported on respective front surfaces of first and second support plates; and an adhesive member that adheres to the front surfaces of the first and second support plates and the back surface of the display and fastens them together. In the portable information device, an area that overlaps with at least a folding area includes a weak adhesive section in which an adhesive force of the adhesive member between the first and second support plates and the display is reduced to be lower than the other section or a non-adhesive section that does not adhere to at least either the first and second support plates or the display. The portable information device further includes a magnet provided below the back surface of the display and in a position that overlaps with the folding area. The magnet can attract a magnetic body.

Claims (22)

1. A portable information device comprising:

a first chassis member;

a second chassis member foldably connected to the first chassis member;

a first support plate fastened to the first chassis member;

a second support plate fastened to the second chassis member and located adjacent to the first support plate;

a display having a back surface that is supported on respective front surfaces of the first support plate and the second support plate, the display including a folding area that is folded when the first chassis member and the second chassis member are folded towards one another; and

an adhesive member that adheres to the respective front surfaces of the first support plate and the second support plate and to the back surface of the display, and fastens the first support plate and the second support plate and the display together,

wherein an area of the adhesive member that overlaps with at least the folding area includes a weak adhesive section in which an adhesive force of the adhesive member with the respective front surfaces of the first support plate and the second support plate, and with the back surface of the display, is lower than another section of the adhesive member or a non-adhesive section of the adhesive member that does not adhere to at least either the respective front surfaces of the first support plate and the second support plate or the back surface of the display,

the display includes a magnetic body that overlaps with at least the folding area, and

the portable information device further includes a magnet adjacent the back surface of the display and in a position that overlaps with the folding area, the magnet being able to attract the magnetic body.

2. The portable information device according to claim 1 , wherein

when the portable information device is in an operable form in which the first chassis member and the second chassis member are on substantially a same plane, the magnet attracts the magnetic body and pulls the display to respective sides of the first support plate and the second support plate, and

when the portable information device is in a storage form in which the first chassis member and the second chassis member are folded until the first chassis member and the second chassis member come face-to-face, and the display is folded, the magnet is disposed in a position farther away from the magnetic body than when the portable information device is in the operable form.

3. The portable information device according to claim 1 , wherein the magnet is disposed on a back surface of at least one of the first support plate and the second support plate.

4. The portable information device according to claim 1 , wherein at least a portion of the magnet is embedded in at least one of the first support plate and the second support plate.

5. The portable information device according to claim 2 , further comprising a spine member that stretches between an inner surface of the first chassis member and an inner surface of the second chassis member so as to cover a gap formed between respective adjacent first edges of the first chassis member and the second chassis member when the portable information device is in the storage form, wherein

one end of the spine member is non-slidably fixed to the inner surface of the second chassis member so that the spine member slides in a direction from the second chassis member to the first chassis member along the inner surface of the first chassis member, and

the magnet is provided on the spine member.

6. The portable information device according to any one of claim 1 , wherein the magnetic body is a rolled metallic sheet-like member.

7. The portable information device according to claim 6 , wherein the sheet-like member is made of stainless steel.

8. The portable information device according to claim 6 , wherein the sheet-like member extends over an entire surface of the display.

9. The portable information device according to claim 1 , wherein the magnet is disposed in a position near at least both ends of the folding area in a longitudinal direction.
