<P>PROBLEM TO BE SOLVED: To provide an opening/closing device which can stably/smoothly perform a moving operation of moving plate with respect to a fixed plate by one operation. <P>SOLUTION: The opening/closing device includes a hinge arm 18 in which one end is connected to a fixed plate 12 at a first shaft section A1, the other end is connected to a moving plate 14 at a third shaft section A3, a sliding groove 18b is formed between the first shaft section A1 and third shaft section A3, the moving plate 14 is moved between a closing position and opening position by revolving of the hinge arm 18 around the first shaft section A1 as a center; a linking arm 22 in which one end is connected to the fixed plate 12 at a second shaft section A2 and the other end is connected to a fifth shaft section A5; and a sliding arm 20 in which one end is connected to the moving plate 14 at a fourth shaft section A4, and the other end is connected to the fifth shaft section A5. When the moving plate 14 moves between the closing position and opening section, the fifth shaft section A5 slides within a sliding hole 18b in accompanying rotations of the sliding arm 20 and linking arm 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
