An electronic device comprises a first part having a first surface and a second part having a second surface confronting the first surface. The electronic device further comprises a slide module comprising a sledge part fixed on the first surface and a base part fixed on the second surface. The slide module permits a linear movement of said first part and said second part, wherein a maximum overlap of the sledge part and the base part occurs with a minimum overlap of said first part and said second part and a minimum overlap of the sledge part and the base part occurs with a maximum overlap of said first part and said second part.
