Abstract

PURPOSE: To simplify the construction of the titled device by using a synchronous motor capable of rotating in both forward and backward directions as a drive source for opening and closing a shutter.
CONSTITUTION: The shutter 3 is opened and closed by the synchronous motor 6 which rotates in one direction at the time of opening the shutter 3 and in the opposite direction at the time of closing the shutter 3. Switches 13 and 14 for detecting the completely opened condition and the completely closed condition of the shutter 3, respectively, are provided on opposite sides of an arm part 11 of a connector 10 for the shutter 3. For instance, when opening the shutter 3, an operation controlling switch 9 is changed over to a fixed contact 9C side so that a fan motor 5 and the synchronous motor 6 are rotated. As a result, a wire 9 is wound around a drum 8, the shutter 3 is gradually opened to the completely opened condition, and the arm part 11 depresses a button 13' of the switch 13 to change over a movable contact piece 13A to a fixed contact 13B, thereby stopping the motor 6. In this opening operation, the arm part 11 is separated from a button 14' of the switch 14 and a movable contact piece 14A is changed over from a fixed contact piece 14C to a fixed contact 14B, thereby providing a preparatory condition for the subsequent closing operation of the shutter.
