Description of the Related Art In conventional fiberscopes and electronic endoscopes, a flexible tube is used to connect an operation unit or an image monitor arranged outside a human body to an imaging head introduced into the human body. Configuration. Even if the imaging head unit is reduced in size and diameter to reduce the pain of the subject, the pain that the “tube” passes through the throat of the subject cannot be fundamentally eliminated. Therefore, in recent years, an electronic endoscope apparatus having a capsule-shaped imaging head unit without a tube and an image monitor unit separated from the other has been proposed, but the conventional proposal content is merely an idea, and actual production and use is actually performed. Has not reached the stage of doing.
