Abstract: An electronic device includes a housing, a circuit board, a switch, and a side key. The housing has a plurality of side walls. The circuit board is disposed in the housing. The switch is disposed at an inner surface of the housing relatively close to the circuit board. The side key disposes through one of the side walls, and the location of the side key is corresponding to the switch. When the side key is pressed, the side key contacts the switch to make the switch electrically connected with the circuit board.

Abstract: A portable electronic device includes a first body, a second body and a guiding assembly. The first body is disposed adjacently to the second body. The second body has a groove with a positioning portion. The guiding assembly has a guiding part fixed at the first body. The guiding part has a guiding portion slidingly disposed at the groove to allow the second body to slide relatively to the first body. When the guiding portion slides to the positioning portion, the second body is capable of rotating relatively to the first body, and the guiding portion is allowed to be fastened in the positioning portion. Thus, an angle is formed between the second body and the first body.

Abstract: A first housing of an electronic device is connected to a second housing of the electronic device in a slidable manner. A rack is positioned on the first housing. A gear unit and a hinge are positioned on the second housing. The gear unit engages with the rack, and a gear positioned at an end of the hinge engages with the gear unit.
