Abstract
A guide detection type rotary encoder has first through fourth transmission windings, first through fourth reception windings, and first through fourth flux coupling bodies. The first and second transmission windings, the first and second reception windings, and first and second flux coupling bodies each form first and second angle detection tracks which generate an Ntime and Ntime cyclic change at one rotation of the first rotor. The third and fourth transmission windings, the third and fourth reception windings, and third and fourth flux coupling bodies each form third and fourth angle detection tracks which generate an Ntime and Ntime cyclic change at one rotation of the second rotor. Nand Nare different, and Ntime and Nare different.
