Title (EN) OPTICAL ENCODER
(FR) CODEUR OPTIQUE
(KO) 광학 인코더
Abstract: front page image
(EN) The present invention relates to an optical encoder, comprising: a light-receiving unit having a light-receiving pattern for outputting eccentricity data; and a scale moving relative to the light-receiving unit and having a projection pattern. The light-receiving pattern is formed into a shape, the width of which continuously increases or decreases, thereby enabling the reliable detection of an eccentric state of the scale.
(FR) La présente invention concerne un codeur optique, comprenant : une unité réceptrice de lumière ayant un motif de réception de lumière pour délivrer des données d'excentricité; et une échelle se déplaçant par rapport à l'unité de réception de lumière et ayant un motif de projection. Le motif de réception de lumière est façonné suivant une forme dont la largeur augmente ou diminue de façon continue, permettant ainsi la détection fiable d'un état excentrique de l'échelle.
(KO) 본 발명의 광학 인코더는 편심 데이터를 출력하는 수광 패턴이 형성된 수광부 및 상기 수광부에 대해 상대 이동하고, 투영 패턴이 형성된 스케일을 포함하고, 상기 수광 패턴은 폭이 연속적으로 증가하거나 감소하는 형상으로 형성됨으로써, 스케일의 편심 상태를 신뢰성 있게 파악할 수 있다.
