摘要： The present invention is intended to be able to ensure detecting whether an open-circuit occurs to a feeder within short time with simple configuration. A receiving apparatus 2 according to the present invention receives image information transmitted from a capsule endoscope 3 through a coaxial cable and a receiving antenna selected and switched to from among coaxial cables 9a to 9d connected to receiving antennas 8a to 8d, respectively by a changeover switch 20. The receiving apparatus 2 includes a changeover switch 22, an open-circuit detecting circuit 23, and a control unit 26. The changeover switch 22 branches the coaxial cables 9a to 9d near the changeover switch 20, and selects and switches to one of the branched coaxial cables. The open-circuit detecting circuit 23 applies a direct-current voltage to the coaxial cable selected by the changeover switch 22 through a constant-current source 203, and detects whether an open-circuit occurs to the coaxial cable by determining whether a voltage of the coaxial cable is grounded. The control unit 26 controls the changeover switch 22 to perform selection/switching, and controls the open-circuit detecting circuit 23 to perform open-circuit detection synchronously with the selection/switching control over the changeover switch 22.

摘要： 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).

摘要： In a capsule endoscope that functions as one example of a body insertable apparatus, a first imaging mechanism, a second imaging mechanism, a data generator, and a timing controller are provided on a same imaging board. The first imaging mechanism and the second imaging mechanism are arranged inside an outer casing member that determines an outer shape of the capsule endoscope. The data generator generates image data based on electric signals obtained by the imaging mechanisms. The timing controller controls driving timings of the first imaging mechanism, the second imaging mechanism, and the data generator. Since the aforementioned elements are formed on the same board, increase in number of the board can be suppressed.
