Abstract

A foldable information processing apparatus includes a hinge part that foldably couples two housings with each other, a crank-type structured flexible printed circuit board that passes through the hinge part and electrically connects the two housings to each other, and a protector that protects an end surface of the flexible printed circuit board from a contact with the hinge part.

Claims (18)

1. A foldable information processing apparatus comprising:

a hinge part that foldably couples two housings with each other;

a crank-type structured flexible printed circuit board having a fixed area, a movable area and an in-hinge area therebetween that enters said hinge part through a groove thereof and passes through said hinge part and electrically connects two printed circuit boards located in said two housings, respectively; and

a protector that protects an end surface of said flexible printed circuit board from a contact with said hinge part, said end surface being a portion of said in-hinge area that is opposed to said groove,

wherein said protector is a resin member including a tape that is provided to be disposed on an inner surface of said hinge part and separates the end surface of said flexible printed circuit board from said hinge part.

2. A foldable information processing apparatus comprising:

a hinge part that foldably couples two housings with each other;

a crank-type structured flexible printed circuit board having a fixed area, a movable area and an in-hinge area therebetween that enters said hinge part through a groove thereof and passes through said hinge part and electrically connects two printed circuit boards located in said two housings, respectively; and

a protector that protects an end surface of said flexible printed circuit board from a contact with said hinge part, said end surface being a portion of said in-hinge area that is opposed to said groove,

wherein said protector is a member that is provided to be disposed on said flexible printed circuit board, extends along an inner surface of said hinge part, and separates said hinge part from the end surface of said flexible printed circuit board.

3. A foldable information processing apparatus according to claim 2 , wherein said member is a part of said flexible printed circuit board.

4. A foldable information processing apparatus according to claim 2 , wherein said flexible printed circuit board includes plural layers, and the member is one of layers at both end layers in the plural layers.

5. A foldable information processing apparatus according to claim 3 , wherein the member dispenses with a signal line in said flexible printed circuit board.

6. A foldable information processing apparatus comprising:

a hinge part that couples two housings with each other;

a crank-type structured flexible printed circuit board that passes through said hinge part, and electrically connects two printed circuit boards located in said two housings;

a first protector that is provided on said flexible printed circuit board, extends along an inner surface of said hinge part, and contacts said hinge in substitute for the end surface of said flexible printed circuit board; and

a second protector that is a tongue part that extends from a part of said flexible printed circuit board, and contacts said hinge part.
