PROBLEM TO BE SOLVED: To realize an introduction device into the inside of a subject for a capsule type endoscope, or the like, to move in inside of the subject at a speed low enough to acquire information inside the subject. SOLUTION: An outer packaging structure for the capsule type endoscope 2 is equipped with an imaging window part 32 disposed to correspond to an imaging field of view of a CCD (charge coupled device) 24 and an outer packaging case member 29 comprising a case part 32 firmly fixed to the imaging window part 32 in a watertight manner for protecting the inside. An uneven member 30 interacts with an inner wall of a moving path when the introduction device moves in the inside of the subject by forming the uneven member 30 as an effective means in a region corresponding to the case part 32 on the outer surface of the member 29. Consequently, the moving speed of the endoscope 2 is reduced by a drag caused by the interaction. COPYRIGHT: (C)2006,JPO&NCIPI
