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 realize a receiving system that can excellently receive radio signals before and after a body insertable device, which is a radio signal source, is inserted into a subject, the receiving system has a first receiving antenna (1), a second receiving antenna (2), and a receiving apparatus (3). The first receiving antenna (1) is used when the body insertable device is outside the subject. The second receiving antenna (2) is used when the body insertable device is inserted into the subject. The receiving apparatus (3) performs a receiving processing on radio signals received through the first receiving antenna (1) or the second receiving antenna (2). In the receiving system, a receiving antenna connected to an antenna connector (13) provided in the receiving apparatus (3) is switched between the first receiving antenna (1) and the second receiving antenna (2) corresponding to a difference in propagation states of radio signals transmitted from the body insertable device before and after the body insertable device is inserted into the subject. Consequently, the receiving system that can excellently receive the radio signals before and after the body insertable device is inserted into the subject is realized.

摘要： Each of detecting circuits 36a, 36d, 36f, and 36h detects a key signal such as a horizontal synchronization signal, a vertical synchronization signal, a capsule ID, a WB coefficient, and error information, i.e., a key signal superposed on RF signals received by an RF receiving unit 33. Each of determining units 36b, 36c, 36e, 36g, and 36i determines whether an image is valid or invalid based on the result of detection. A recording deciding unit 36k decides whether to record the image information in a storage unit 35 or not based on the result of determination. Thus, a receiving apparatus 3 can stop recording the image information received when a trouble occurs, thereby preventing defective images from mixing into the recorded image information, and preventing a recorded image size from becoming large, whereby necessary images can be recorded within a predetermined examination time.

摘要： An object of the invention is to receive, with a high sensitivity, a radio signal transmitted within a short time before a capsule endoscope reaches the stomach of a subject and acquire, in a satisfactory state, information on the interior of the subject such as image data picked up by the capsule endoscope. The receiving apparatus according to the invention includes a plurality of receiving antennas including a specified receiving antenna for receiving a radio signal from a capsule endoscope before the stomach is reached, a switching controller, an arrival determining unit and a mode switching unit. The switching controller performs a control operation for switching to and maintaining the receiving antenna in an initial mode or a control operation for switching to the receiving antennas in a normal mode. The arrival determining unit determines whether the capsule endoscope has reached the stomach or not. The mode switching unit instructs the switching controller to perform the control operation for switching to the initial mode, and upon determination that the stomach has been reached, gives the instruction to perform the control operation for switching to the normal mode.
