Title
(EN) POSITION DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE POSITION
(JA) 位置検出装置
Abstract
(EN) This position detection device detects the position of a lens holder (120) in an X-axis direction on the basis of a change in an output value of a first magnetic sensor (160). The position detection device detects the position of the lens holder (120) in a Y-axis direction on the basis of a change in an output value of a second magnetic sensor (170). The position detection device detects the position of the lens holder (120) in a Z-axis direction on the basis of the changes in the output values of the first magnetic sensor (160) and the second magnetic sensor (170).
(FR) Ce dispositif de détection de position détecte la position d'un support de lentille (120) dans une direction d'axe X sur la base du changement d'une valeur de sortie d'un premier capteur magnétique (160). Le dispositif de détection de position détecte la position du support de lentille (120) dans une direction d'axe Y sur la base du changement d'une valeur de sortie d'un second capteur magnétique (170). Le dispositif de détection de position détecte la position du support de lentille (120) dans une direction d'axe Z sur la base des changements des valeurs de sortie du premier capteur magnétique (160) et du second capteur magnétique (170).
(JA) 位置検出装置は、第1磁気センサ(160)の出力値の変化に基づいてレンズホルダ(120)のX軸方向における位置を検出する。位置検出装置は、第2磁気センサ(170)の出力値の変化に基づいてレンズホルダ(120)のY軸方向における位置を検出する。位置検出装置は、第1磁気センサ(160)および第2磁気センサ(170)の出力値の変化に基づいてレンズホルダ(120)のZ軸方向における位置を検出する。
