摘要： An optical encoder comprising a light-receiving part having photodiodes equal in number to the common multiplier of a number of slits facing the light-receiving part and a number of movement information signals. Output terminals of the photodiodes are connected so that the movement information signals are respectively obtained by adding output signals of the plurality of photodiodes out of the photodiodes equal in number to the common multiplier. The twelve photodiodes are balancedly arranged corresponding to three slits and a light-receiving area of each photodiode is made smaller by subdiving each photodiode.
