Abstract: An articulated hinge that can hold a folded part of a flexible display sheet that deforms following the opening and closing of the first and second casings, and an electronic gear using this articulated hinge, an articulated hinge couples the first and second casings of an electronic gear in a foldable manner by a relative folding motion between the open and closed positions where an articulated hinge is arranged on the back side of a flexible display sheet attached over the inner surfaces of both the first and the second casings is disclosed. The articulated hinge has a frame portion, wherein an odd number (1+2n, where n is an integer greater than or equal to 2) of vertical frames are arranged in parallel along a width direction, where its shorter-side direction is the width direction and its vertical direction is a vertical direction.

Abstract: An object of the invention is to provide a document cover closer as well as office equipment having such a document cover closer, wherein it is possible to finely adjust a spring force and to set its adjusting range within a wide range, as well as to downsize the apparatus.To achieve the above-mentioned object, in a document cover closer 5 according to the invention, a supporting part 20 is rotatably attached to an attaching part 10 being a base via a first hinge pin 81, and a lift part 30 to which the document cover is fixed is rotatably attached to the supporting part 20. In an elastic force adjusting portion 60, as the document cover is opened and the supporting part 20 is erected, the spring force adjusting screw 80 extending perpendicular to an axial direction of the first hinge pin 81 is rotated; then, as the spring force adjusting cam plate 61 moves in a forward and backward direction along cam tracks of cam surfaces 52L, 52R extending along a forward and backward direction of the second spring receiving portion 42, a spring sheet plate 70 as well moves integrally to compress or expand a first coil spring 43 and the second coil spring 44 to adjust a spring force.
