Description
Claims (4)
- 軸とこの軸の外周側に取り付けられた永久磁石を有する回転子と、回転子の外側に配置した固定子とを備え、この固定子は、ケーシングと、ケーシングの内周側に保存したヨークと、ヨークの内周側に配置したコイルとを有するものであるスキャナにおいて、
前記回転子の永久磁石は、半径方向に凹んだ溝が外周部に形成されており、前記コイルの内側のほぼ中央部に前記コイルよりも周方向長さが短い第2のコイルを対向する前記永久磁石に形成した前記溝の内側に食い込むように設けた、ことを特徴とするスキャナ。 - 前記永久磁石は、前記軸の周方向に複数極設けられており、その周方向長さは前記コイルの周方向長さよりも±10°の範囲で相違していることを特徴とする請求項1に記載のスキャナ。
- 前記永久磁石の溝の数を、永久磁石の極数の2倍にしたことを特徴とする請求項1に記載のスキャナ。
- 前記永久磁石の溝の周方向幅を、前記軸の揺動角度よりも大きくしたことを特徴とする請求項3に記載のスキャナ。
