<P>PROBLEM TO BE SOLVED: To provide an opening/closing device that exhibits braking action when an upper unit case 3 is closed and moves smoothly when it moves when it is opened for rotation. <P>SOLUTION: A lower unit case 2 including a lower guide member 6 and an upper unit case 3 including an upper guide member 7 are fixed through a hinge part 4 so as to be openable, closable and pivotal vertically. A moving body 10 slidably coupled along the lower guide member 6 and the upper guide member 7 includes a first link 1 and a second link 12 pivotally linked to the first link 11. When the upper unit case 3 is closed, an angle formed by the first link 11 and the second link 12 becomes larger, a brake member 25 disposed on the lower side of the first link 11 is inserted into an open groove 16 formed on the lower unit case 2, and the moving body 10 stops. <P>COPYRIGHT: (C)2012,JPO&INPIT |
