6. An inclination detecting method comprising:
a step (A) of adding/removing a built-in weight to/from a weight sensor;
a step (B) of calculating a weighing value of the built-in weight; and
a step (C) of obtaining an apparatus inclination angle from an arc-cosine of the weighing value of the built-in weight and a theoretical value of the built-in weight.
