Abstract
The rotation detection apparatus includes a rotatable member rotatable with rotation of a motor and having multiple pattern element portions in its rotational direction, a signal outputter to output a detection signal changing in response to rotation of the pattern element portions, and a memory storing correction values each provided for each of the pattern element portions and used to perform correction of an error in a relation between rotational positions of the rotatable member and the change of the detection signal. A corrector performs the correction with reference to a reference position of the rotatable member in an origin state where a driven member driven by the motor is located at its origin position and by using each of the correction values for each change of the detection signal when the rotatable member is rotated from the reference position.
