Abstract (en)
[origin: EP0909886A2] A position controller comprising: a step motor (20) which drives an apparatus (4); a reference position detection device (17) which detects that said apparatus (4) is located at a reference position and outputs a reference position detection signal; and a control device (40) which, based on the reference position detection signal from said reference position detection device (17), controls said step motor (20) so as to control a position of said apparatus (4), wherein, when said apparatus (4) is moved and said reference position detection device (17) is to be adjusted, said control device (17) drives said step motor (20) by an angle smaller than the regular angle. <IMAGE>
