<P>PROBLEM TO BE SOLVED: To provide a reduction gear mechanism between an input shaft and an output shaft, and use each origin detection signal from Hall elements provided on an input shaft side and an output shaft side to detect an origin position of the output shaft. <P>SOLUTION: An origin position detection mechanism according to the invention detects a second origin position (12a) of an output shaft (4) with an AND signal (20) of a first origin detection signal (11A) from a first Hall element (11) detecting a first origin position (11a) and a second origin detection signal (12A) from the second Hall element (12) detecting the second origin position (12a). <P>COPYRIGHT: (C)2013,JPO&INPIT |
