リエンコーダを用いたリニアセンサ。 A linear sensor in which the rotating shaft of a rotary encoder is fixed to a rotating roller connected to one end of a movable element of a linear motor via a bearing, includes a rotating roller, a guide rod that supports the rotating roller, and an auxiliary that holds the guide rod together with the rotating roller. A linear encoder using a rotary encoder is characterized in that permanent magnets are provided near these members so that a magnetic path is formed between them and the bearing shaft, and a magnetic attraction force is applied between the rotating roller and the guide rod. sensor.
