HINGE DEVICE AND ELECTRONIC APPARATUS USING THE SAME

摘要

An object of the present invention is to provide a novel hinge device and an electronic instrument using the hinge device which is extremely high in commercial value. A hinge device for pivoting a first member ( 1 ) and a second member ( 2 ), in which a first coupling member ( 3 ) having a shaft portion ( 5 ) is provided in one of said first member ( 1 ) and said second member ( 2 ), a second coupling member ( 4 ) having a bearing hole portion ( 6 ) for bearing said shaft portion ( 5 ) is provided in the other member, said first coupling member ( 3 ) and said second coupling member ( 4 ) are coupled with each other through the shaft portion ( 5 ) to be rotatable relative to each other so that the first member ( 1 ) may be rotated through the shaft portion ( 5 ) relative to the second member ( 2 ) in any direction of right and left directions, and an excessive rotation preventing mechanism ( 7 ) for preventing relative excessive rotation of the first member ( 1 ) in any direction of the right and left directions relative to the second member ( 2 ) is provided.
