Abstract: The invention provides a receiving apparatus that can suppress data loss when an antenna is detached. When a non-connection of an antenna is detected (step S103: Yes) after a recording operation is started (step S101: Yes), the receiving apparatus operates a warning unit to issue a warning to a user to the effect that the antenna is detached (step S105). Therefore, the receiving apparatus does not issue a warning (step S102) when there is no problem even when the antenna is detached, such as when an examination is not yet started (step S101: No). When the antenna is detached in a state that the use of the antenna is essential during an examination, the receiving apparatus notifies the user such as a subject about this fact, thereby prompting the user to correct the connection of the antenna. As a result, the data loss when the antenna is detached can be suppressed.
