Therefore, the first slide member 30 is automatically moved upward in the remaining section by the elastic restoring force of the springs 69 even if the user no longer applies the force to the first cover part 5.

When the first cover part 5 is completely opened during this process, the first and second rotating plates 61 and 62 of the elastic module 60 rotate by the elastic restoring force of the springs 69 and the slide plate. Sliding in the opposite direction along 64, these springs 69 are restored to their original state.

Here, the elastic module 60 is to maintain a state inclined in the other direction with respect to the moving direction of the first cover portion (5).

The first slide member 30 is located at the other end (lower end) of the first base plate 10, and the second slide member 40 is located at the other side (upper part) of the second base plate 20. ) At the end.

On the other hand, when the first and second cover parts 5 and 7 are closed again with the first and second cover parts 5 and 7 fully open relative to the main body part 3 as described above, When pushed downward with respect to the first cover part 5, the first and second cover parts 5 and 7 are operated while the respective parts are operated in the reverse operation of the first and second cover parts 5 and 7. ) Is completely closed in the same state as in FIG.
