Biaxial Hinge and Terminal Device Using the Same

A biaxial hinge of a terminal device, such as tablet notebook PC, which couples a first casing on the keyboard side and a second casing on the 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 operating mechanism working on a keyboard, rubber feet and others provided on said first casing;
• said biaxial hinge portion comprising:
• a first hinge shaft attached to said first casing;
• and
• a second hinge shaft attached to said second casing,
• said first hinge shaft being coupled in parallel to said second hinge shaft via a plurality of joint members, said first hinge shaft and said second hinge shaft being both rotatable;
• said first hinge shaft and said second hinge shaft being rotatable in a synchronous manner with each other but in different directions via a synchronous rotation mechanism;
• said actuating mechanism comprising:
• a cam member attached to said first hinge shaft, said cam member being rotatable together with opening and closing operations of said first casing and said second casing;
• an actuating member being slidable along with a rotary movement of said cam member;
• and
• elastic means for urging a sliding movement of said actuating member in one direction,
• said actuating member actuating said operating mechanism.
