PROBLEM TO BE SOLVED: To eliminate a backup failure, when a main power supply is turned off by consuming a backup battery also, when the main power supply is turned on and eliminating voltage delays. SOLUTION: In this method for preventing voltage delays of the battery for backup in this optical encoder and the optical encoder, a switching part (4) is connected between the main power supply (2) and the battery (6) for backup, and power is supplied from the battery (6) for backup also, when the main power supply (2) is on to prevent voltage delays.
