Description

【発明の詳細な説明】 発明の目的 この発明は複写機用定着ローラ等の高周波誘導加熱ロー
ラに関するものである。
従来例の構成とその問題点 静電式普通紙複写機の熱定着方式は、一般的にハｃｒ／
７’７ラン１ｔ−熱源としたものが用いられているが、
この方式は、副射熱および対流による熱伝導によ〕定着
ローラを熱するため、所定の温度に到達する時間（ウオ
ームアツプ時間）が多（かかるという欠点があった。そ
こで、この欠点を補う方式として、定着ローラ本体に高
周波誘導加熱を流し、そのジュール熱を熱源とする方式
が提案された。
この高周波誘導加熱の原理は、金属製ローラ本体の近傍
に誘導コイルを配し、そのコイμに高周波電流を流すこ
とにより、コイルによって生ずる磁界で変圧器の二次巻
線に起電力を生ずるのと同様にローラ本体自身に起電力
を誘起させて誘導電流を流し、その電流によりロー＝？
不体の抵抗Ｒでジュール熱を発生させてローラ本体を加
熱するものである。この場合、ローラ本体と誘導コイル
の位置関係は、ローラ本体の外部に誘導コイルを巻装配
置する方法や、第１図に示すように、円筒状ロープ本体
１の何方に誘導コイＡ／２を渦巻状に巻装配置する方法
が考えられるが、いずれの場合も、誘導コイ／Ｌ／２に
よシ生じる磁束をローラ本体１全体へ均一に供給できな
いため、ローワ本体ｌを均一加熱できなｈという問題を
有していた。
発明の目的 この発明の目的は、ローワ本体を均一加熱できる高周波
誘導加熱ロー″Ｆを提供することである。
発明の構成 この発明の高周波誘導加熱ローラは、導電性円筒状ロー
ワ本体内に同心状に配置し九円筒状ボビンの外周に、誘
導コイ〜を螺旋状に巻装したもので、誘導コイルへの通
電により発生する磁束をローラ本体全体に均一に供給し
て、ローワ本体の均一加熱を図る。
実施例の説明 この発明の一実施例を第２図および第３図を用いて説明
する。すなわち、この高周波誘導加熱ローブは、両図に
示すように、金属製円筒状ロープ本体３内に絶縁性円筒
状ボビン４を同心状に配置し、このポビン４の外周に誘
導コイＡ１５を螺旋状に均等巻装したものである。
このように、誘導コイ３１５をポビン４に螺旋状に均等
巻装してローワ本体３内に同心状に配置したため、誘導
コイ／Ｌ１５への通電によって生じる磁束をローフ本体
３全体に均一に供給でき、ローラ本体３全体に均一に誘
導電流をＩ起させて、ローラ本体３全体を均一に加熱で
きる。特に、複写機用定着ローラに２いては、定着不良
の発生を防止するためにローラ本体３の愚度分石の均一
化を図ることが強く望まれているため、上記高周波誘導
加熱ロー′５を複写機用定着ローフとして使用するとそ
の効果が大きい。
発明の効果 この発明の高周波誘導加熱ロー９によどれば、ローフ本
体を均一加熱できるという効果が得られる。
【図面の簡単な説明】
第１図は提案例の正面図、＠２図はこの発明の一実施例
の断面図、第３図はボビンに誘導コイルを巻装した正面
図である。
