Body insertable apparatus and body-insertable apparatus system
First Claim
1. A body insertable apparatus which is introduced inside a subject and travels through the inside of the subject, comprising:
- an optical system which focuses light introduced from outside onto a predetermined surface;
an outer casing member which houses the optical system and includes a window portion to introduce light from outside into the optical system;
an attachment member which is formed at a predetermined portion of the window portion; and
a traction member whose one end is secured by the attachment member and which extends by a predetermined distance towards an outside of the window portion in a direction from a principal point of the optical system toward the predetermined portion.

Abstract
To provide a capsule endoscope in which a degree of appearance of a sting-like member in a captured image is reduced, a capsule endoscope (2) includes an optical system (18) having a predetermined principal point, an imaging unit (19) which captures light focused by the optical system (18), and an attachment member (28) which is arranged at a predetermined position on a window portion (17a) having optical transparency and forming a portion of an outer casing member (17) housing the optical system (18) and the imaging unit (19). The capsule endoscope (2) further includes a traction member (29) having one end secured to the attachment member (28) and extending by a predetermined distance in a direction from the optical system (18) toward a position of the attachment member (28). Since the traction member (29) has such a structure, an appearance of an image of the traction member (29) can be reduced at the imaging unit (19).

17. A body-insertable apparatus system, comprising:
-
a body insertable apparatus which is introduced inside a subject, captures an intra-subject image, and transmits a radio signal containing the intra-subject image captured; and a receiving device which receives the radio signal transmitted from the body insertable apparatus, wherein the body insertable apparatus includes an optical system which focuses light introduced from outside onto a predetermined surface, an outer casing member which houses the optical system and includes a window portion to introduce light from outside to a field of view defined by the optical system, and a traction member whose one end is secured by an attachment member formed at a predetermined portion of the window portion and which extends by a predetermined distance towards an outside of the window portion in a direction from a principal point of the optical system toward the predetermined portion, and the receiving device includes a receiving circuit which performs a predetermined receiving process on the radio signal received by a receiving antenna, and a signal processing unit which extracts image information from a signal subjected to the receiving process by the receiving circuit.
