<p><P>PROBLEM TO BE SOLVED: To solve a problem in a conventional position detecting method of a wind direction changing blade of an air conditioner, wherein the blade may be largely deviated from an stopping intended position since, an analog output signal is inputted into an AD port, and sampling is carried out in a certain time. <P>SOLUTION: The blade of the air conditioner can be stopped at an optional position by providing a photosensor 1, and a position detector 4 having a slit synchronously rotating with a motor driving the blade for converting output of the photosensor 1 into pulse signals. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
