Abstract

PURPOSE:To open and close a shutter quietly, by a method wherein an operating unit for the opening and closing of the shutter is connected to the coupling unit of a driving member while a fan motor is connected to a signal generator. CONSTITUTION:When an operating signal is outputted from a signal generator 40, the pivoting of a fan moor 3 is started and an opening command is given to an operating motor 16 through a command switching device 22 when the operating signal is received whereby the operating motor 16 is rotated to move a driving member 11 from the closed position of a shutter to the opened position of the same and open the shutter 5. On the other hand, when a stopping signal is outputted from the signal generator 40, the rotation of the fan motor 3 is stopped and a closing command is given to the operating motor 16 through the command switching device 22 when the stopping signal is received, whereby the operating motor 16 is rotated to move the driving member 11 from the opened position of the shutter to the closed position of the shutter thereby closing the shutter 5.
