Claim Text:
1. A slave station comprising: a transmission device extracting control data from a transmission signal on common data signal lines connected to a control section, the transmission device transmitting a monitoring data signal to the common data signal lines; an indicating device; an input device; and an input-output device transmitting and receiving data to and from the indicating device and the input device, the input device comprising a switch portion and a detecting portion, and the switch portion comprising: a flexible cylindrical member bendable in any directions, the flexible cylindrical member being detachably attached to a housing forming a body, the housing comprising the transmission device, the input-output device, and the detection portion; a rigid rod member attached to a free end of the flexible cylindrical member; a flexible rod member extending from the base end of the rigid rod member toward the base end of the flexible cylindrical member through the inside of the flexible cylindrical member; and a guiding member comprising an insertion opening for the flexible rod member, the guiding member holding the flexible rod member while allowing for movement of the flexible rod member in the shaft line direction, wherein a detection element is formed at the end portion of the flexible rod member protruded from the insertion opening of the guiding member, the detection element comprising an electrostatic substance and a magnetic metal substance, and the detection element comprising a reflective surface on the end surface in the shaft line direction or a side surface parallel to the shaft line; and wherein when a force is applied to the rigid rod member in a direction perpendicular to the shaft line of the rigid rod member, the flexible rod member moves in the shaft line direction and the detection portion detects the detection element moving away therefrom.
