Portable information device
View Patent ↗A portable information device is capable of stably supporting a foldable display. The portable information device has a support plate which is fixed to the inner surface sides of a first chassis member and a second chassis member and supports the rear surface of a display. The support plate has a first plate member disposed on the inner surface side of the first chassis member, a second plate member disposed on the inner surface side of the second chassis member, and a flexible sheet-like member connecting the first plate member and the second plate member so as to be foldable into a double-folded state.
1. A portable information device comprising:
a chassis member; and
a display provided on a side of an inner surface of the chassis member,
wherein:
the portable information device contains a support plate containing a pitch-based fiber reinforced resin plate in which a resin layer containing a matrix resin is on a surface of a base material layer in which a pitch-based carbon fiber having conductivity is impregnated with the matrix resin and wherein the support plate supports a rear surface of the display on a side of an inner surface of the chassis member,
the support plate has a conductive portion in which a part of the resin layer is removed and the base material layer is exposed, and
the conductive portion is electrically connected with the chassis member.
2. The portable information device according to claim 1 , wherein:
the conductive portion is fixed to the chassis member by a screw having conductivity in the support plate.
3. The portable information device according to claim 1 , wherein:
the conductive portion is on a rear surface of the support plate facing the inner surface of the chassis member and is not formed on a surface of the support plate supporting the rear surface of the display.
4. The portable information device according to claim 1 , wherein:
the chassis member has a first chassis member and a second chassis member foldably connected with the first chassis member by connecting each one end portion disposed adjacent to each other by a hinge mechanism,
the support plate has a first plate member disposed on a side of an inner surface of the first chassis member and has a second plate member disposed on a side of an inner surface of the second chassis member,
the conductive portion in the first plate member is electrically connected with the first chassis member, and
the conductive portion in the second plate member is electrically connected with the second chassis member.
