1. A hinge device for rotatably connecting first and second sections of an apparatus, the hinge device comprising:
- a shaft comprising;
first and second ends, the first end being connected to the first section; and
first and second portions, the first portion having a diameter greater than a diameter of the second portion, the first portion cooperating with the second portion to form an edge;
means, connected to the second section, for supporting the second section, the supporting means being rotatably connected to the second portion of the shaft; and
ring-shaped spring means, compressed between the edge and the supporting means, for generating friction between the first edge and the supporting means to suppress rotation of the supporting means around the shaft when the supporting means is rotatably moved.

Abstract
A hinge device comprising a shaft to be connected at one end to a first member, a bracket mounted on the shaft, for supporting a second member such that the second member rotates around said shaft, and wave washers held and compressed between said shaft and said support means. The wave washers generates a friction between said shaft and the second member when the first and second members are rotated relative to each other around said shaft, thus suppressing the rotation of the first and second members.

11. A hinge device for rotatably connecting a first and second section of an apparatus, the hinge device comprising:
-
a shaft comprising; first and second ends, the first end being connected to the first section; and first and second portions, the first portion having a diameter greater than a diameter of the second portion, the first portion cooperating with the second portion to form an edge; a bracket rotatably connected to the second portion of the shaft, the bracket supporting and being connected to the second section thereby enabling the second section to be movably rotated around the shaft; and spring means, compressed and disposed between the edge and the bracket, for generating friction between the edge and the bracket to suppress the rotation of the bracket when the bracket is rotatably moved around the shaft.

12. A portable computer comprising:
-
a base unit including a keyboard and a shaft supporter; a display unit rotatably connected to the base unit, the display unit having a bracket connecting section, the display unit being rotatable between a first position for covering the keyboard and a second position for operating the computer; a shaft comprising; first and second ends, the first end being connected to the shaft supporter; and first and second portions, the first portion having a diameter greater than a diameter of the second portion, the first portion cooperating with the second portion to form an edge; a bracket removably attached to the bracket connecting section and being rotatably connected to the second portion; spring means, compressed and disposed between the edge and the bracket, for generating friction between the bracket and the edge to suppress rotation of the display unit when the display unit is rotated between the first position and the second position. - View Dependent Claims (13, 14)
