<p><P>PROBLEM TO BE SOLVED: To solve a problem in a position detecting method for a wind direction changing blade of a conventional air conditioner that as an analogue output signal is input to an AD port to be sampled in a given time, a position is largely displaced from a stop-intended position. <P>SOLUTION: This air conditioner comprises a photointerruptor 1, and a position detector 4 rotating in synchronization with a motor driving the blade and having a slit 5 for ON/OFF of a pulse signal of the output of the photointerruptor 1, so that the blade of the air conditioner can be stopped at an optional position by counting the pulse signal output from the photointerruptor 1 during an ON time of the pulse signal input to the photointerruptor 1. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
