Abstract:
1. An electronic device comprising: a movable unit having a top surface, the top surface including a plurality of buttons configured to receive input from a user; a main body in which the movable unit is stowed and from which the movable unit is deployed by sliding the movable unit, the main body having a first surface opposed to the top surface when the movable unit is in a stowed state and in a deployed state; and a changing mechanism which changes a vertical distance between the top surface and the first surface during a sliding operation of the movable unit so that the top surface and the first surface during the sliding operation are separated from each other by a distance greater than a distance between the top surface and the first surface in the stowed state, said distance substantially perpendicular to said sliding, the changing mechanism including a first protrusion and a first guiding groove engaged with the first protrusion so as to guide the first protrusion, the first guiding groove being horizontal in a central portion and being sloped up along both first and second outermost end; and wherein the movable unit includes a side surface, wherein the main body includes a second surface facing the side surface, and wherein the first protrusion is provided on the side surface of the movable unit, and the first guiding groove is provided in the second surface; and wherein the changing mechanism further includes a second protrusion provided on the second surface, and a second guiding groove provided in the side surface and engaged with the second protrusion so as to guide the second protrusion, the second guiding groove being horizontal in a central portion and being sloped down along both first and second outermost end portions thereof.
