Abstract: A rotation angle detection apparatus includes an incremental rotary scale and a detector. The rotary scale includes both a detection region having a scale formed therein for detecting a rotation angle of an object and a non-detection region having no scale formed therein. The detector generates, based on an input signal indicating change in the position of the scale of the detection region which changes according to change in the rotation angle of the object, an electrical signal that periodically changes according to the change in the position of the scale of the detection region. Further, the detector detects the rotation angle of the object based on the electrical signal. Furthermore, the detector detects a reference angle for the rotation angle of the object by counting the number of positional changes from an end of the scale of the detection region; the positional changes are indicated by the input signal.
