As a result, the first engaging portion 51 moves downward against the spring bias of the first spring member 61.
Along with this, the second engagement portion 52 of the lock portion 5 also moves downward, and the second engagement portion 52 is disengaged from the second engagement receiving portion 23 of the second housing 2, and FIG. As shown in FIG. 2, the second housing 2 slides in the closing direction by the spring bias of the third spring member 63 and is disposed at the closed position.

  Further, by sliding the first housing in the closing direction, the first engagement portion 51 of the lock portion 5 moves to the first engagement receiving portion 13 and moves upward by the spring bias of the first spring member 61. Thus, the first housing 1 is engaged with the first engagement receiving portion 13 of the first housing 1, and the first housing 1 is also disposed at the closed position.

According to the above-described openable small electronic device, the sliding operation of the second housing 2 and the second housing 2 are performed with respect to the first housing 1 and the second housing 2 arranged at the closed position. The first display 11 and the second display 21 are aligned on substantially the same plane only by sequentially performing the pressing operations of pressing.
On the other hand, for the first housing 1 and the second housing 2 arranged at the open position, a pressing operation for pressing the first housing 1 and a sliding operation of the first housing 1 are sequentially executed. As a result, the first housing 1 and the second housing 2 are disposed at the closed positions.
