BIAXIAL HINGE AND ELECTRONIC DEVICE USING THE SAME
First Claim
1. A biaxial hinge of an electronic device, such as tablet notebook PC, which couples a first casing on a keyboard side and a second casing on a display side, thereby these casings being openable and closable 360 degrees relative to each other,said biaxial hinge comprising a biaxial hinge portion and an actuating mechanism for actuating an operation means working on a keyboard portion, rubber feet and others provided on said first casing or said second casing;
- said biaxial hinge portion comprising;
a means for controlling the rotation, said means making a first hinge shaft attached to said first casing via a first attaching plate and a second hinge shaft attached to said second casing via the second attaching plate rotatable in parallel via a plurality of joint members, as well as controlling the rotation of the first hinge shaft and the second hinge shaft;
said actuating mechanism comprising;
a fixed cam member, said first hinge shaft passing through said fixed cam member in a rotatable manner;
a slide cam member attached facing said fixed cam member, thereby said slide cam member being slidable in one direction in an axial direction of said first hinge shaft; and
a link member provided between said slide cam member and said attaching plate for converting a slide movement of said slide cam member in an axial direction of said first hinge shaft into a movement perpendicular to said axial direction and transferring the converted movement to said operation means.

Abstract
A biaxial hinge which allows a first casing having a keyboard and a second casing having a display to open and close 360 degrees relative to each other. The biaxial hinge ensures that the keyboard, rubber feet, and other parts can sink relative to the first casing. The biaxial hinge includes a biaxial hinge portion and an actuating mechanism. The biaxial hinge portion includes a rotation controlling unit. The actuating mechanism includes a fixed cam part, a slide cam part facing the fixed cam part, and a link part.
