摘要： PROBLEM TO BE SOLVED: To provide an optical encoder having a simple signal processing circuit, capable of preventing positioning precision from getting worse when rotated at a low speed, and capable of reducing a mounting area to be constituted compactly.
SOLUTION: This optical encoder is provided with a light emitting element and a light-receiving element 10.

A prescribed multiplication frequency generating part 12 outputs a multiplication signal D1 having a prescribed multiplication of frequency with respect to the moving frequency. Frequency detecting parts 13, 14 obtain a theoretical value expressing which frequency area the moving frequency is located in out of a high or low frequency area with respect to a blocking frequency, using an output D3 of a filter 14 having the prescribed blocking frequency. A frequency switching part 15 outputs the multiplication signal D1 as an output signal D4, when the moving frequency is located in the low frequency area, and outputs a signal having 1/n (n is 2 or more of natural number) of frequency with respect to the frequency of the multiplication signal D1, when the moving frequency is located in the high frequency area.
