摘要

PURPOSE: A sliding-up type portable digital communication device is provided to install the first protruded region having stepped portions protruded in vertical direction, and to install the second protruded regions protruded in side direction from the first protruded region, thereby conveniently moving a sliding housing. CONSTITUTION: A sliding housing(20) slides down as keeping opposite to a body housing(10) in parallel. The first protruded region(22) has at least more than one stepped portion(S1,S2) protruded in vertical direction from an upper side(20a) of the sliding housing(20). At least more than one second protruded region(24a) has at least more than one stepped portion(S3,S4) protruded in side direction from the first protruded region(22). The first protruded region(22) is overall extended in length direction of the sliding housing(20). The second protruded region(24a) is extended along the length direction of the sliding housing(20), and is protruded in both side direction of the first protruded region(22).
