Abstract: An electronic device is provided, and includes a keyboard module and a display module. The keyboard module includes a first key area, a second key area, and a joining area disposed between the first key area and the second key area. The display module has a connecting surface detachably disposed on the joining area and electrical connected to the keyboard module. The display module is stood on the keyboard module to face a first direction in a first operation mode and a second direction is opposite to the first direction in a second operation mode.

Abstract: A portable electronic device includes a main body, a cap body and a hinge assembly. The cap body is movably attached to the main body, and the hinge assembly is disposed between the main body and the cap body. The hinge assembly includes a sliding portion and a rotating portion connected to each other. When the cap body and the main body are totally overlapped, the cap body is selectively to rotate or to slide with respect to the main body over the hinge assembly.

Abstract: An electronic device and a protection cover thereof are provided. The electronic device includes a cap body, a main body, a flexible printed circuit board and a protection cover. The protection cover includes a receiving portion and a combining portion. The receiving portion has a first end and a second end, wherein the first end is coupled to an upper surface of the main body and the second end connects to the combining portion. As the cap body moves from a first position to a second position on the main body, the combining portion is coupled to a bottom surface of the cap body, so that when the cap body rotates in the second position, the protection cover moves along with the cap body and covers the flexible printed circuit board.
