Abstract
(EN) Provided is an encoder comprising a rotating body which is attached to a rotating shaft and on which is formed a pattern for the detection of rotation information pertaining to the rotating shaft, a detection unit which detects the pattern on the rotating body, and a computation unit which obtains the rotation information pertaining to the rotating shaft on the basis of the detection results from the detection unit, wherein the rotating body is divided, along the rotation direction of the rotating shaft, into a plurality of parts upon each of which a portion of the pattern is formed. The encoder can be attached to and detached from rotating shafts such as those of drive units wherein an operating part is provided to one end of the rotating shaft and the other end of the rotating shaft is coupled to a motor.
(FR) L'invention concerne un codeur comprenant un corps rotatif qui est fixé à un arbre rotatif et sur lequel est formé un motif pour la détection d'informations de rotation relatives à l'arbre rotatif, une unité de détection qui détecte le motif sur le corps rotatif, et une unité de calcul qui obtient les informations de rotation relatives à l'arbre rotatif sur la base des résultats de détection provenant de l'unité de détection. Le corps rotatif est divisé, le long de la direction de rotation de l'arbre rotatif, en une pluralité de parties sur chacune desquelles une portion du motif est formée. Le codeur peut être fixé à des arbres rotatifs et détaché de ceux-ci, tels que ceux d'unités d'entraînement, une partie d'actionnement étant fournie à une extrémité de l'arbre rotatif et l'autre extrémité de l'arbre rotatif étant couplée à un moteur.
(JA) 回転軸に取り付けられて、前記回転軸の回転情報を検出するためのパターンが形成された回転体と、前記回転体の前記パターンを検出する検出部と、前記検出部の検出結果に基づいて、前記回転軸の前記回転情報を求める演算部と、を備えるエンコーダであって、前記回転体は、前記回転軸の回転方向に沿って、それぞれ前記パターンの一部が形成された複数のパーツ部に分割されているものである。一端部に操作部が設けられ、他端部がモータに連結されたような回転軸を有する駆動部のその回転軸に対し、エンコーダを取り付けたり、又は取り外したりすることができる。
