<p>A structure for opening/closing a cover for a case in which when the cover is closed, the cover closes an opening provided in an upper surface of the case, whereas when the cover is opened, the cover is guided at its engaging portions in guides provided on the case, so that the cover is folded in halves upward at a connection, the folded cover is moved by a movable element via one end of the case to below the case and then disposed there. For example, a cover 11 foldable in halves at a first hinge 14 is provided turnably by a second hinge 17 to a turnable plate 16 which is provided turnably by a third hinge 18 to a right-hand end of a device case 1. A pair of guide grooves 19 is provided on a device case 1 such that the pair of guide grooves extends to guide a corresponding pair of engaging pins 20 provided at a left-hand end of the cover 11 from a left-hand end of the upper surface of the case 1 to near a lower right-hand end of the case 1. When the cover 11 is opened, the engaging pins 20 are guided along the guide grooves 19 to fold the cover in halves. The folded cover 11 is then moved to below the case 1 via the right-hand end of the case 11 by the turnable plate 16 and then disposed below the case 1. Thus, when the cover is opened, it neither becomes an obstacle nor dangles. Thus, this structure improves handiness.</p> |
