Abstract
Description
図1は、この発明の実施の形態1に係る磁気センサ装置の主走査方向に直交する断面図である。図2Aは、実施の形態1に係る磁気センサ装置を搬送路側から見た斜視図である。図2Bは、実施の形態1に係る磁気センサ装置を底面側から見た斜視図である。図中でX、Y、Zと記されている3軸は、理解を容易にするために定めた直交座標系を表す。
次に、磁気センサ装置の温度が変化したときの磁石9の挙動を説明する。
図11は、この発明の実施の形態2に係る磁気センサ装置の主走査方向に直交する断面図である。実施の形態2では、ケース2の材料として、熱伝導率の低い樹脂に代えて熱伝導率の高い、例えば、マグネシウムなどの金属を用いる。一般的なマグネシウムの熱伝導率は156[W/m・K]である。
図12Aは、この発明の実施の形態3に係る磁気センサ装置のガイドを搬送路側から見た斜視図である。図12Bは、実施の形態3に係る磁気センサ装置のガイドを底面側から見た斜視図である。図12Cは、実施の形態3に係る磁気センサ装置のガイドの側面図である。実施の形態3の磁気センサ装置は、実施の形態2とはガイドの形状が異なる。その他の構成は、実施の形態2と同様である。
図14は、この発明の実施の形態4に係る磁気センサ装置の主走査方向に直交する断面図である。実施の形態4では、ガイド14eを、樹脂を材料として作成し、側壁部の高さを磁石9の途中までにする。そして、ヨーク10のY方向の移動を規制するために、磁石9の側面とヨーク10を覆うヨーク保持部14fを設ける。その他の構成は、実施の形態3と同様である。
