Patent ID: 7376450

Claim:
A slidable and automatic rotatable apparatus disposed in a portable electronic device and providing the portable electronic device with a first status and a second status, the portable electronic device having a first housing and a second housing, the apparatus comprising: a third housing, fixed on the first housing and movably connected with the second housing, the third housing comprising: a first track, having a first position, a second position and a third position, the second position being positioned between the first position and the third position; a second track, having a fourth position and a fifth position; and a first rib disposed on a first side of the second track, a protruding part disposed on the second housing and opposite to the first track; and a rotary module passing through the second track, wherein a first end of the rotary module is fixed on the second housing, a second end of the rotary module is disposed between the first housing and the third housing, and the second end of the rotary module has at least a protruding point in contact with the first rib; wherein when the portable electronic device is operated under the first status, the protruding part and the rotary module are respectively positioned at the first position and the fourth position; wherein when the third housing slides against the second housing and causes the protruding part to slide to the second position from the first position along the first track, the rotary module also slides to the fifth position from the fourth position along the second track and releases an elasticity force when the rotary module reaches the fifth position, the elasticity force rotates the rotary module and enables the protruding point to push the first rib, so that the protruding part slides to the third position from the second position and that the third housing moves against the second housing, and the portable electronic device is switched to the second status; wherein when the protruding part slides to the second position from the third position, the protruding part causes the rotary module to rotate at the fifth position so as to store the elasticity force in the rotary module.
