<p>PURPOSE:To prevent the play of a lid plate by providing the lid plate capable of rotating for the opening/closing according to the projection and the pulling-in of a mechanical deck from and into a hole in the case of opening/closing a hole provided on a cabinet. CONSTITUTION:When the mechanical deck 12 straightly moves to an outside through the hole 10a of the cabinet 10, the lid device is moves straightly from a closing position A to a opening position B. When the mechanical deck 12 straightly moves to the outside, a lever 20 is also moved upward. When the lever 20 is moved, a fitting plate 18, a leaf spring 16 and the lid plate 14 are integrally rotated around a rotation axis line passing through a pin joint or a screw 30a. The lever 20 is straightly moved corresponding to the straight motion of the mechanical deck 12 and simultaneously rotated around the rotation axis line passing through the joint or the screw 30c of a second edge part corresponding to the rotary motion of the lid plate 14. When the lid device is at the opening position, the leaf spring 16 of the lid plate 14 is supported by the lever 20, consequently the lid plate 14 and the leaf spring 16 are not vibrated.</p> |
