Abstract: A hinge device comprises: an attachment member attached on an apparatus body side; a supporting member pivotally supported by the attachment member through hinge pins; a document press-contacting plate attached to the supporting member; compression springs elastically provided between the supporting member side and the attachment member in such a manner that the supporting member is enforced to pivot in a direction that the document press-contacting plate is opened; a damper set inside the compression springs and provided between the attachment member side and the free end side of the supporting member so that an abrupt pivoting at and from a predetermined angle measured from the supporting member is buffered.

Abstract: In a slide hinge for a small-sized information terminal composed of a first casing and a second casing, to achieve a slide hinge having a function of relatively and automatically sliding the first casing and the second casing from predetermined slide positions, a slide hinge in which a first casing provided with a keyboard portion and a second casing provided with a display portion are relatively slid includes: a linear slide means provided between the first casing and the second casing; and a turning means for performing a turning operation accompanying linear slide operations of the first casing and the second casing by the slide means, the turning means being configured to generate rotation torque from a predetermined turning angle so that the first casing and the second casing automatically and relatively slide in an opening direction and/or a closing direction depending on the slid position thereof.
