The link mechanism 4 incorporates a soft locking mechanism, and the urging force of the first spring member 61 is received by the soft locking by the soft locking mechanism. Therefore, the second housing 2 is maintained in the fully open position against the urging force of the first spring member 61.

  On the other hand, when moving both housings 1 and 2 from the fully open position to the fully closed position, the first housing 1 is pushed downward from the fully open position. As a result, the third arm 43 of the link mechanism 4 moves to the lower position, and the fourth arm 44 moves in the direction opposite to the movement direction of the third arm 43 (upward) in conjunction with the movement of the third arm 43. To do. As a result, the second housing 2 is pushed up, and the first housing 1 and the second housing 2 move to the intermediate position shown in FIG.

Then, as shown in FIG. 17A, the first housing 1 is manually slid from the second open position to the closed position against the urging force of the second spring member 62, and in this process, the lock 5 After the first engaging portion 51 comes into contact with the first inclined surface 14, the first engaging portion 51 slides on the first inclined surface 14 in conjunction with the sliding operation of the first housing 1. The first engaging portion 51 moves in the direction opposite to the urging direction (downward) against the urging force of the first spring member 61.
Accordingly, the second engaging portion 52 moves in the same direction (downward) as the first engaging portion 51 and is detached from the second engaging receiving portion 251. Therefore, as shown in FIG. The two housings 2 are moved (slid) from the first open position to the closed position by the urging force of the third spring member 63.

  At the same time or after the second housing 2 has slid from the first open position to the closed position, the first housing 1 is further slid manually from the second open position to the closed position. One housing 1 moves to the closed position.
