ABSTRACT:
A folding electronic device comprises a body and a cover member, rear walls of which are rotatably coupled with each other by hinges. When the cover member is closed, the rear wall of the cover member is positioned rearwardly beyond the rear wall of the body while the lower end of the rear wall of the cover member is positioned downwardly beyond the upper end of the rear wall of the body. A clearance defined between the rear walls of the body and the cover member is blocked by a closing member which is provided in the body. A spring is mounted on the closing member to rearwardly urge the same. Due to the urging force of the spring, the closing member is in contact with the rear wall of the cover member when the cover member is closed and when the same is opened by 180.degree., as well as when the same is being opened/closed. Thus, no foreign matter enters the interior through the clearance defined between the rear walls of the body and the cover member to disconnect an interconnection sheet of the folding electronic device.
