装置。 The lift control mechanism that raises and lowers the bed by driving the elevator based on the operation of the lift push button switch is equipped with a self-holding circuit that continues to drive the elevator and raise and lower the bed even after the lift push button switch returns. In the electrically operated elevating bed, the elevating control mechanism includes set position detection means for detecting that the bed has reached a safety setting position before the final movement position, and the A safety control device for an electrically operated elevating bed, characterized in that it is provided with a self-holding release means that automatically releases the self-holding of the self-holding circuit and thereafter drives the elevator in response to the operation of the elevating push button switch. .
