A configuration in which only a power switch is provided may be employed.

  As shown in FIG. 3, the capsule endoscope 103 has a transparent dome having a cross-sectional shape of an exterior member 114 having a shape in which one end of a cylinder is closed, and a substantially hemispherical shape rounded. It consists of a mold cover 114a. The dome-shaped cover 114 a is adhered to the end of the exterior member 114 on the opening side with an adhesive, and closes the exterior member 114. Therefore, the exterior member 114 and the dome-shaped cover 114a form a capsule shape and are in close contact with each other in a watertight manner.

In addition, the external device 105 is connected to a plurality of antennas 111 a to 111 d constituting the antenna unit 104 via the antenna changeover switch 145. Here, the plurality of antennas 111 is four, 111a to 111d, but is not necessarily limited to this number. The antenna selection operation by the antenna selection circuit 146 is controlled by the output of the reception circuit 133. When a reception start instruction is input from the operation unit 113, signals transmitted from the capsule endoscope 103 are received sequentially by the antenna 111a, the antenna 111b, the antenna 111c, and the antenna 111d every other frame.

  The reception circuit 133 compares the reception intensity at each antenna obtained from the reception intensity signal from each antenna, selects the optimum antenna for receiving the image signal, and switches the antenna for image reception to the antenna switching circuit 45. A control signal is sent out. As a result, when there is another antenna having a higher reception intensity than the antenna currently receiving the image signal, the antenna that receives the image signal is switched from the next frame. That is, first, the external apparatus 105 receives the reception start instruction input from the operation unit 113, and then receives the reception intensity signal transmitted from the capsule endoscope 103 as the antenna 111a, the antenna 111b, the antenna 111c, and the antenna 111d. , Sequentially. Next, the reception circuit 133 compares the reception intensity at each antenna obtained from the reception intensity signal from each antenna, and the antenna 111i (i is a, b, c) with the maximum reception intensity at that time. Or d), the antenna selection circuit 146 sets the antenna selection circuit 145 so that an image signal is received by the antenna 111i. For example, when the reception intensity of the antenna 111a is the maximum, the antenna 111a is designated as an image signal reception antenna, and the remaining antennas 111b, 111c, and 111d are designated as reception intensity signal reception antennas. Is done. After one frame period, the capsule endoscope 103 transmits an image signal to the antenna 111. The transmitted image signal is received by the external device 105 by the antenna 111a having the maximum reception intensity specified by the method described above. Since the position of the capsule endoscope 103 moves inside the subject 102, the reception intensity of the image signal received by each of the plurality of antennas 111 also varies with the movement. For this reason, it is necessary to change the image signal receiving antenna for each frame so that the image signal can be received using the antenna 111i having the maximum reception intensity at all times using the method described above.

  An image signal received using the antenna 111 i is received in the external device 105 via a reception circuit 133 and a signal processing circuit 135 connected to the reception circuit 133, and a compact flash (R) memory connected to the signal processing circuit 135. The image information can be recorded in the memory means 147 such as a hard disk. As shown in FIG. 4, the image signal processed by the signal processing circuit 135 can be displayed on the spot as an image by the liquid crystal monitor 112 connected to the signal processing circuit 135.
