  As shown in FIG. 3, a recording medium loading unit 52 is electrically connected to such a processing circuit 53 via a cable 521.

  The recording medium loading unit 52 has a slot shape having an opening 522, and the recording medium M is loaded (stored) and taken out through the opening 522.

  The recording medium M loaded in the recording medium loading unit 52 is electrically connected to the processing circuit 53 via the cable 521 described above. As a result, the processing circuit 53 can record information on the recording medium M as described above.

  In particular, the recording medium loading unit 52 is provided adjacent to the second connector 51 described above, and when the first connector 43 and the second connector 51 are connected, the blocking member 45 prevents the opening 522 from being formed. Almost the entire area is covered.

  Here, the action of the blocking member 45 (extraction blocking means) in the receiving apparatus 3 configured as described above will be described in detail.

  As shown in FIG. 3, when the first connector 43 and the second connector 51 are connected, that is, when the antenna unit 4 is attached to the receiving unit 5, the controller 55 (see FIG. 2), it is detected that the first connector 43 and the second connector 51 are connected, and the information received by the antenna unit 4 is processed by the processing circuit 53 and recorded on the recording medium M.

  When the first connector 43 and the second connector 51 are thus connected, the blocking member 45 as described above covers almost the entire area of the opening 522 of the recording medium loading unit 52. That is, when the first connector 43 and the second connector 51 are connected, the blocking member 45 is in a removal blocking position that blocks the recording medium M from being removed from the recording medium loading unit 52.

  If the blocking member 45 can block the removal of the recording medium M when the first connector 43 and the second connector 51 are connected, the blocking member 45 covers substantially the entire area of the opening 522 of the recording medium loading unit 52. It may not be covered, and may be configured to cover a part of the opening 522 of the recording medium loading unit 52.

  On the other hand, as shown in FIG. 4, when the connection between the first connector 43 and the second connector 51 is released, that is, when the antenna unit 4 is detached from the receiving unit 5, the processing circuit 53 The controller 55 (see FIG. 2) detects that the first connector 43 and the second connector 51 are not connected, and the processing circuit 53 protects the information in the recording medium M in the recording medium M. Stop (stop) recording of information for. That is, for a general file system, all open files are closed.

  Thus, when the connection between the first connector 43 and the second connector 51 is released, the blocking member 45 as described above retracts from the opening 522 of the recording medium loading unit 52. That is, when the connection between the first connector 43 and the second connector 51 is released, the blocking member 45 is in a take-out permission position that allows the recording medium M to be taken out from the recording medium loading unit 52. . At this time, since the recording of information on the recording medium M is stopped as described above, even if the recording medium M is taken out, damage or loss of information in the recording medium M can be prevented.

  As described above, according to the receiving device 3, it is possible to prevent the recording medium M from being taken out during reception / recording of information without providing a mechanism for detecting an operation for taking out the recording medium M. Further, unlike the conventional case in which only a warning is issued, it is possible to prevent the recording medium M from being taken out due to vibration or erroneous operation during reception / recording of information.

  Particularly, since the blocking member 45 is configured to be in the extraction blocking position as described above in conjunction with the connection between the first connector 43 and the second connector 51, the antenna unit is attached to the receiving unit. The recording medium can be prevented from being taken out. Further, when the means (controller 55) for detecting the attachment / detachment of the antenna unit 4 to / from the receiving unit 5 detects the detachment of the antenna unit 4, recording of information is stopped (stopped) while the information in the recording medium M is protected. Thus, it is possible to prevent the recording medium M from being taken out during information recording.

  For this reason, the receiving device 3 can prevent the inspection by the capsule endoscope 2 from being wasted.

  Further, the blocking member 45 is configured to cover the opening 522 of the recording medium loading unit 52 when in the removal blocking position as described above, and to retract from the opening 522 when in the removal allowable position. Therefore, it is possible to visually recognize from the outside that the removal of the recording medium M is blocked (prohibited), and it is easy to distinguish from troubles such as clogging of the recording medium M in the recording medium loading unit 52, for example. In addition, a mechanism for performing such distinction is not required.

  Moreover, in the present embodiment, the blocking member 45 is formed integrally with the first connector 43, and the first connector 43 and the second connector 51 are connected, so that the removal blocking position as described above can be obtained. Thus, the removal preventing means can be configured simply by devising the shape of the first connector 43 and the installation position of the recording medium loading unit 52, and the apparatus configuration can be simplified. it can.
