Abstract: A biaxial hinge device, rotates a second member with regard to a first member around a first axis for opening and closing in a vertical direction, and rotates the second member with regard to the first member around a second axis in a horizontal direction. The hinge has a vertical direction rotation controlling mechanism of the second member having the first axis, and a horizontal direction rotation controlling mechanism of the second member having the second axis. A movable stopper is further mounted between a supporting member of the vertical direction rotation controlling mechanism and an attaching member of the horizontal direction rotation controlling mechanism, to which the supporting member is rotably attached. A rotation in a horizontal direction is therefore controlled within a range of predetermined angles, additionally further rotation in the same direction is available via pressing of the second member into the desired direction.

Abstract: To create a torque difference in a tilting hinge, the tilting hinge includes a fixture consisting of a fixing plate portion to be fixed to the body of a portable computer and a bearing plate portion bent perpendicularly to the fixing plate portion; a rotating shaft consisting of a fixing portion to be fixed to a display screen of the portable computer, a large-diameter portion and a small-diameter portion, and born relatively rotatably in a bearing hole formed in the bearing plate portion of the fixture; a first friction washer having a through-hole formed in the center thereof and disposed between the large-diameter portion of the rotating shaft and one side of the bearing plate portion rotatably with the rotating shaft being inserted in the central through-hole or disposed in engagement with the bearing plate portion; a second friction washer having a through-hole formed in the center thereof and disposed fixed to the bearing plate portion with the rotating shaft being inserted at the small-diameter portion
