Biaxial Hinge and Terminal Device Using the Same
First Claim
1. A biaxial hinge which couples a first casing with a second casing, said first casing being thereby capable of opening and closing relative to said second casing,said biaxial hinge comprising:
- a first hinge shaft attached to said second casing via a first attaching plate; and
a second hinge shaft attached to said first casing via a second attaching plate, said first hinge shaft being rotatable in parallel to said second hinge shaft with help of a plurality of joint members;
a means for restricting rotation of said first hinge shaft and said second hinge shaft being provided in association with said joint members;
said means for restricting rotation comprising;
means for generating friction torque, one provided on said first hinge shaft and other on said second hinge shaft;
means for sucking, one provided on said first hinge shaft and other on said second hinge shaft;
stopper means, one provided on said first hinge shaft and other on said second hinge shaft, for restricting a rotation angle of said first hinge shaft and said second hinge shaft; and
a means for synchronously rotating hinge shafts which allows one of said first hinge shaft and said second hinge shaft to synchronously rotate with a rotation of other hinge shaft, thereby one hinge shaft rotating in a direction opposite to other hinge shaft.

Abstract
A biaxial hinge in which a first casing and a second casing of a terminal device can open and close 360 degrees relative to each other, with a simplified structure, enhanced opening and closing speed and an improved operability. A first hinge shaft attached to the second casing via a first attaching plate is rotatable in parallel to a second hinge shaft attached to the first casing via a second attaching plate with help of several joint members. A module for restricting rotation of the first hinge shaft and the second hinge shaft is provided in association with the joint members. The module for restricting rotation includes modules for generating friction torque, modules for sucking, stopper modules for restricting a rotation angle of the first hinge shaft and the second hinge shaft, and a module for synchronously rotating hinge shafts.
