FOLDING ELECTRONIC DEVICE

摘要

A folding electronic device operable without losing a balance at the gravity center of an entire casing even if the attitude of the casing is rotated for use so that image information can be easily observed and capable of preventing an erroneous operation in the standby state. In a cellular phone (1A) having an upper casing (2) with a display part on the principal plane thereof, a lower casing (3) with a first operation part (31) on the principal plane thereof, and a hinge part (4) rotatably connecting the first casing (2) to the second casing (3), a second operating part (5) rotated according to the opening/closing operations of the hinge part (4) and concealed between the casings (2) and (3) when the upper and lower casings (2) and (3) are folded and exposed to the outside when the upper casing (2) is opened is formed at the hinge part (4).
