Title (EN) POSITION DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE POSITION
(JA) 位置検出装置
Abstract:
(EN) Provided is a position detection device that makes it possible to accurately acquire an absolute value. Specifically, an absolute track 23 of a magnetic scale 2 is provided with a first track 24 having an absolute pattern 24a and a second track having a magnetization pattern 25a arranged opposite to the absolute pattern 24a. An absolute value output unit 34 is provided with: a first signal output unit 41 that reads the absolute pattern 24a of the first track 24 and outputs a first signal E1; and a second signal output unit 42 that reads the magnetization pattern 25a of the second track 25 and outputs a second signal E2. An absolute value ABS is output on the basis of a differential signal D of the first signal E1 and the second signal E2.
(FR) La présente invention concerne un dispositif de détection de position qui permet d’acquérir précisément une valeur absolue. Spécifiquement, une piste absolue 23 d’une échelle magnétique 2 est pourvue d’une première piste 24 comportant un motif absolu 24a et d’une deuxième piste comportant un motif de magnétisation 25a agencé face au motif absolu 24a. Une unité de sortie de valeur absolue 34 est pourvue de : une première unité de sortie de signal 41 qui lit le motif absolu 24a de la première piste 24 et délivre en sortie un premier signal E1 ; et une deuxième unité de sortie de signal 42 qui lit le motif de magnétisation 25a de la deuxième piste 25 et délivre en sortie un deuxième signal E2. Une valeur absolue ABS est délivrée en sortie sur la base d’un signal différentiel D du premier signal E1 et du deuxième signal E2.
(JA) アブソリュート値を正確に取得できる位置検出装置を提供すること。具体的には、磁気スケール2のアブソリュートトラック23は、アブソリュートパターン24aを有する第1トラック24と、アブソリュートパターン24aと反対に配列された着磁パターン25aを有する第2トラックを備える。アブソリュート値出力部34は、第1トラック24のアブソリュートパターン24aを読み取って第1信号E1を出力する第1信号出力部41と、第2トラック25の着磁パターン25aを読み取って第2信号E2を出力する第2信号出力部42と、を備え、第1信号E1および第2信号E2の差動信号Dに基づいてアブソリュート値ABSを出力する。
