In order to provide a biaxial hinge and terminal device which ensure that a first and a second casings can open and close 360 degrees relative to each other, as well as enable a keyboard portion and rubber feet to sink relative to the upper surface of the first casing, from a predetermined opening/closing angle, the biaxial hinge comprises a biaxial hinge portion and an actuating mechanism for actuating operating mechanism(s) working on keyboard and rubber feet. Further, the actuating mechanism comprises a cam part moving in association with the movement of the biaxial hinge portion and together with opening/closing operations of the first and the second casings, and a slide part of which an end contacts with the cam part. The slide part is further provided on the attaching plate attached to the first and the second hinge shafts so as to start moving from a predetermined opening/closing angle. |

1. 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. |
