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 closeraccording to the invention, a supporting partis rotatably attached to an attaching partbeing a base via a first hinge pin, and a lift partto which the document cover is fixed is rotatably attached to the supporting part. In an elastic force adjusting portion, as the document cover is opened and the supporting partis erected, the spring force adjusting screwextending perpendicular to an axial direction of the first hinge pinis rotated; then, as the spring force adjusting cam platemoves in a forward and backward direction along cam tracks of cam surfacesL,R extending along a forward and backward direction of the second spring receiving portion, a spring sheet plateas well moves integrally to compress or expand a first coil springand the second coil springto adjust a spring force.
