Abstract:
A position detecting apparatus for a moving object driven by a motor rotatable in forward and reverse directions, the apparatus comprising:a moving contact plate connectable to an output shaft of the motor and rotatable with the output shaft;a cover plate accommodating the moving contact plate rotatably therein and having a stopper protrusion which stops rotation of the moving contact plate at a specified rotational position of the output shaft; anda fixed sliding contact fixed to the cover plate and slidable on the moving contact plate to detect the specified rotational position of the output shaft,wherein the moving contact plate has at least one of two types of moving contact patterns, one of which is for a forward rotation direction of the output shaft and the other of which is for a reverse rotation direction of the output shaft, so that the fixed sliding contact detects the specified rotational position of the output shaft when the moving contact plate is stopped from rotating by the stopper protrusion.
