Claim:
1. A biaxial hinge of a terminal device, consisting of 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 via said biaxial hinge, said biaxial hinge comprising a biaxial hinge portion and an actuating mechanism for actuating an operating mechanism working on a keyboard or rubber feet provided on said first casing; said biaxial hinge portion comprising: a first hinge shaft attached to a first actuating plate mounted on said first casing; and a second hinge shaft attached to a second actuating plate mounted on 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 rotatable in a synchronous manner with each other but in different directions via a synchronous rotating mechanism; 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 synchronous rotation mechanism comprising: a gear supporting member which passed through said first hinge shaft and said second hinge shaft in a rotatable manner, an intermediate gear provided between a lower projecting portion and an upper projecting portion of said supporting member in a rotatable manner; a first gear attached to the first hinge shaft and meshed with a lower bevel tooth portion of said intermediate gear; and a second gear attached to the second hinge shaft and meshed with an upper bevel tooth portion of the intermediate gear; 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 slidably mounted on said first actuating plate along with said cam member; and elastic means interposed between said actuating member and said first actuating plate for urging a sliding movement of said actuating member in one direction, said actuating member abutting against said cam member and actuating said operating mechanism.
