PROBLEM TO BE SOLVED: To enhance reliability of an operation in which an opening/closing body means is closed by being guided into a guiding groove, when the closing of the opening/closing body means is started along the guiding groove in synchronization with the closing of a shield door means such as a fireproof door equipped with the guiding groove. SOLUTION: The timing of output of a shield door closing signal output from a closing checking means is set as a time point when a recessed area of the guiding groove of the fireproof door during rotational movement crosses a recessed area of the guiding groove when the fireproof door is stopped by abutting on a door stop portion on the upside of an peripheral edge. Thus, since a shutter curtain is closed from the time point of crossing of both of them onward, a leading end of the shutter curtain is surely inserted into the guiding groove as a guide rail, and the shutter curtain is moved for closing along an inner wall surface of the guiding groove.
