。[Scope of Claim for Utility Model Registration] In a rotary encoder that detects a rotation angle, an incremental pattern section that is composed of a plurality of data tracks with different index angle resolutions and generates a pulse train proportional to the rotation angle, and a single data track. an encoder disk provided with an absolute pattern section that generates an absolute value serving as a reference for the rotation angle; a moving pickup that moves the incremental pattern section of the encoder disk to read the pulse train; and the absolute pattern section. a fixed pickup for reading an absolute value serving as a reference; and a control means for selecting a data track according to the resolution of the indexing angle from among the data tracks of the incremental pattern section and causing the movable pickup to read the selected data track. A rotary encoder characterized by:
