Abstract
A portable telephone allowing the increase of the number of key buttons and the expansion of the area of the display window simultaneously is disclosed. The portable telephone is composed of three units: display unit, speaker unit, and body. The three units are connected at variable angles by means for two hinge shafts. Additionally, the lateral walls are formed on the body to generate friction between the units. Consequently, the tilt angle of the display unit with respect to the body can be held stably to further improve visibility for the user.
