Abstract:
1. A hinge unit for use in an electronic apparatus, said hinge unit comprising: a shaft which comprises a first part, a first rotation stopper, and a second part that is positioned between the first part and the first rotation stopper in an axial direction of said shaft; a first member which holds the first part of said shaft, wherein said first member is not rotatable and is not axially movable with respect to said shaft, and said first member cooperates with the first rotation stopper to define a space between said first member and the first rotation stopper of said shaft along the axial direction of said shaft; a circuit board which comprises a flexible portion which is wound around the second part of said shaft in the space, wherein the flexible portion has an end which is fixed to the second part of said shaft; a second member which is rotatable in a rotating direction with respect to said shaft, and which is not axially movable with respect to said shaft; an intermediate member which is faced to said second member in the axial direction, wherein said intermediate member is not rotatable with respect to the first rotation stopper of said shaft and is axially movable with respect to said shaft; an elastic member which is interposed between said shaft and said intermediate member, and which urges said intermediate member towards said second member in the axial direction; and an engaging structure which engages said second member and said intermediate member with each other in the rotating direction, wherein said engaging structure releases the engagement between said second member and said intermediate member, and said elastic member is energized, in response to a rotating force applied between said second member and said intermediate member.
