Portable Electronic Device having a Protective Foldable Cover with a Built-in Membrane Keyboard

Abstract

A portable electronic device includes a main body, a protective foldable cover, a membrane keyboard and a folding means. The protective foldable cover is attached structurally in a foldable manner to the main body and further has a foldable leaf to cover the main body. The membrane keyboard is mounted to the foldable leaf by facing the main body and is connected signally with the main body. The folding means is to provide at least one stand state for the main body to stand on the foldable leaf of the protective foldable cover and thus to present the membrane keyboard completely to a position in front of the main body.
