Abstract: A body weight threshold determination unit determines that the body weight of a user on a bed is at a body weight threshold or higher, and a center-of-gravity position area determination unit determines that the center-of-gravity position thereof has moved to an abnormal position (monitored area). In such a case, the bed user is detected to be in an abnormal position when a body weight center-of-gravity position monitoring unit detects that such a state has continued for a prescribed length of time or longer. When a back-raising operation has been carried out, a movable bedboard determination unit inputs the movable bedboard information, and a monitored area adjustment unit adjusts the monitored area. The monitored area is thereby constantly set to a suitable area in accordance with the state of the movable bedboard.
