A curving control device to which an electrically-controlled endoscope is connected has a main CPU for primarily performing curving driving control, and a monitoring CPU for monitoring whether the operating state relating to curving actions is normal or abnormal. In the event of detecting an abnormality from the monitoring CPU, the curving control device also performs processing for handling the occurrence of the abnormality, such as outputting an emergency stop through an interlock via the main CPU, turning the main power and the like of a servo driver OFF.

Electrically-operated curving control device

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.
