Abstract
Provided is an angle detection apparatus making it possible to reduce the labor of manufacturing while also suppressing bulkiness. The angle detection apparatus includes a first rotating body (), a second rotating body (), a first transmission mechanism () that causes the second rotating body () to rotate by reducing a speed of a rotation of the first rotating body (), a first angle detector (Ds) that detects a rotational angle of the first rotating body (), another second angle detector (Dm) that detects a rotational angle of the second rotating body (), and a processor () that specifies a number of revolutions (Rs) of the first rotating body (). The processor () specifies the number of revolutions (Rs) while dynamically varying a specification condition for specifying the number of revolutions (Rs) according to a numerical value decided according to the detected rotational angle of the first rotating body () and a reduction ratio (G) of the first transmission mechanism (), and the detected rotational angle of the second rotating body ().
