Abstract

This application discloses an electronic device. The electronic device comprises a first body including an A surface and a B surface that are opposite to each other; a second body including a C surface and a D surface that are opposite to each other; and a connecting piece by means of which the first and the second bodies are connected and the first body is rotatable relative to the second body. A further rotation of the first body around the connecting piece is prevented by the second body when the first body is rotated relative to the second body, by means of the connecting piece, such that the electronic device is at a first posture that is a relative positional posture where value of an angle between the A surface and the D surface is a first angle value within the range of greater than 0° but less than or equal to 90°.

First claim

What is claimed is:

1. An electronic device comprising,
a first body including an A surface, which is planar in whole, and a B surface that are opposite to each other;
a second body including a C surface and a D surface that are opposite to each other; and
a connecting piece by means of which said first and said second bodies are connected and said first body is rotatable relative to said second body;
wherein, the first body further includes a pair of protrusion parts provided respectively at both ends of the connecting piece;
wherein a further rotation of said first body around said connecting piece is prevented by said second body, through a direct contact between a first end surface, that is intersected with said C surface, of the second body and the A surface of the first body, when said first body is rotated relative to said second body, by means of said connecting piece, such that said electronic device is at a first posture that is a relative positional posture where value of an angle between said A surface and said D surface is a first angle value within a first range of greater than 0° but less than or equal to 90°;
wherein the connecting piece is configured to be movable linearly relative to the second body such that, said first body is stably supported by said second body in three conditions as follows: 1) by means of abutting said A surface against said first end surface, and 2) by means of abutting said A surface against an intersection line between said first end surface and said D surface, and 3) by means of an intersection line between said first end surface and said C surface, when said electronic device is at said first posture.

2. The electronic device according to claim 1 , wherein said connecting piece is provided on the first end surface of said second body, and, said connecting piece is exposed relative to said first end surface such that, by means of said connecting piece, said first body is rotatable from an angle value of 0° to a second angle value, relative to said second body, wherein a sum of said first angle value and said second angle value is 360°.

3. The electronic device according to claim 2 , wherein a value of an angle between said first end surface and said C surface is a third angle value within said first range.

4. The electronic device according to claim 3 , further comprising,
a supporting pad provided on said D surface of said second body;
wherein said first body is stably supported by said second body by means of said supporting pad and said first end surface of said second body when said electronic device is at said first posture.

5. The electronic device according to claim 1 , wherein, when said electronic device is at said first posture, said pair of protrusion parts are in contact with a surface where said electronic device is to be placed such that said C surface is not in contact with the surface where said electronic device is to be placed.

6. The electronic device according to claim 5 , wherein, during rotation of said first body relative to said second body, said pair of protrusion parts rotate around a center of said connecting piece and are not in direct physical contact with said first end surface such that rotation of said first body is not obstructed by the pair of protrusion parts.
