    • 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.

    • Image information (corresponding to 1 pixel) of 8 bits acquired by an imaging unit (23) are input into an A/D converter (24a1) provided on an AD board (23a), the input image information are digitally converted to parallel signals of 8 bits, the parallel signals are divided into every 4 bits by a bit-number-converting and outputting circuit (24a2) of an IC configuration, each parallel signals of 4 bits are output to a digital signal processor (25a1) provided on a signal processing board (25a) through four signal lines (80a) of a flexible board (80) by time division, and a predetermined signal processing is performed on the output parallel signals of 4 bits at the digital signal processor 25a1. Consequently, the number of IC pins and the number of signal lines are reduced; therefore, an capsule endoscope is miniaturized, hardening of a board is prevented, and probability of disconnection of the signal lines is reduced.
