Abstract
Abstract The present invention provides a protection device of a personal digital assistant (PDA). The protection device comprises a protection shell and a protection cover body. The protection shell has a receiving space therein to receive a PDA. The protection shell has a window at the front side thereof so that an electronic panel of a PDA can be exposed through the window. One end of the protection shell forms an opening so that a PDA can be conveniently placed into the receiving space. One end of the protection cover body is pivotally connected to the protection shell so that the protection cover body can cover on the window or be unfolded. A protection device of a PDA is thus formed. The present invention can effectively prevent the electronic panel of a PDA from abrasion and breakage and facilitate the use and keeping of a PDA.
