摘要： A cavity insert device comprising an insert section capable of being inserted into tracts and cavities, a detection circuit for detecting conditions of components making up the device, such as an observation device formed at the distal end side of the insert section, and a fuzzy inference section for synthetically determining a plurality of information signals outputted from the detection circuit and producing control signals to control the components. The fuzzy inference section employs inference rules which are empirically considered to be desirable, and control is made by the control signals obtained with the fuzzy inference. The device is thus operated in a nearly optimum state.
