Abstract
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 apparatusaccording to the present invention receives image information transmitted from a capsule endoscopethrough a coaxial cable and a receiving antenna selected and switched to from among coaxial cablestoconnected to receiving antennasto, respectively by a changeover switch. The receiving apparatusincludes a changeover switch, an open-circuit detecting circuit, and a control unit. The changeover switchbranches the coaxial cablestonear the changeover switch, and selects and switches to one of the branched coaxial cables. The open-circuit detecting circuitapplies a direct-current voltage to the coaxial cable selected by the changeover switchthrough a constant-current source, and detects whether an open-circuit occurs to the coaxial cable by determining whether a voltage of the coaxial cable is grounded. The control unitcontrols the changeover switchto perform selection/switching, and controls the open-circuit detecting circuitto perform open-circuit detection synchronously with the selection/switching control over the changeover switch
