Abstract

An electronic apparatus includes: a first chassis member that has a first wall portion; a second chassis member that has a second wall portion and is adjacent to the first chassis member; a hinge device that connects the first chassis member and the second chassis member to be relatively rotatable between a first posture, in which the first chassis member and the second chassis member are laminated so as to overlap each other in a surface normal direction, to dispose the first wall portion and the second wall portion at positions facing each other, and a second posture in which the first chassis member and the second chassis member are arranged side by side in a direction perpendicular to the surface normal direction; and a magnet that has a side surface and a bottom surface and is attached to the first wall portion.

Claims (23)

1 . An electronic apparatus comprising:

a first chassis member that has a first wall portion;

a second chassis member that has a second wall portion and is adjacent to the first chassis member;

a hinge device that connects the first chassis member and the second chassis member to be relatively rotatable between a first posture, in which the first chassis member and the second chassis member are laminated so as to overlap each other in a surface normal direction, to dispose the first wall portion and the second wall portion at positions facing each other, and a second posture in which the first chassis member and the second chassis member are arranged side by side in a direction perpendicular to the surface normal direction;

a magnet that is attached to the first wall portion;

an attracted body that is attached to the second wall portion and attracts the magnet in the first posture;

a display formed in a sheet shape having flexibility, extending over the first chassis member and the second chassis member, and having one side of an outer peripheral edge portion provided at a position facing the first wall portion; and

a control board connected to the display to control display of the display,

wherein a folding portion that is folded to a rear side of the display is provided between the display and the control board so as to wrap around the one side, and

the magnet has a relief portion that faces the folding portion, retreats from the folding portion to avoid the folding portion, and forms a predetermined gap between the relief portion and the folding portion.

2 . The electronic apparatus according to claim 1 ,

wherein the display has a display body including an active region and a non-active region, and

the folding portion is formed by extending and bending a part of the non-active region.

3 . The electronic apparatus according to claim 1 ,

wherein the magnet has a side surface and a bottom surface,

the first wall portion has

an accommodation hole formed to be inserted with the magnet, having an opening portion facing a side of the second wall portion in the first posture, a side inner wall surface supporting the side surface of the magnet, and a bottom wall surface supporting the bottom surface of the magnet, and accommodating the magnet, and

a recessed portion formed in a part of the side inner wall surface of the accommodation hole and recessed in a direction intersecting a direction of inserting the magnet into the accommodation hole, and

the magnet further has a locking part protruding from a part of the side surface and inserted into the recessed portion.

4 . The electronic apparatus according to claim 3 , further comprising a bezel member provided to straddle the first wall portion and the display, and adhesively fixed to the first wall portion and the display,

wherein the bezel member closes the opening portion of the accommodation hole in which the magnet is accommodated.

5 . The electronic apparatus according to claim 1 , further comprising:

a spacer member disposed between the side inner wall surface of the accommodation hole and the side surface of the magnet to prevent the locking part from coming off from the recessed portion by restricting a movement of the magnet in the accommodation hole.
