Abstract
Description
さらに、従来は、医用電気機器本体と制御器のどちらが先に起動するかは使用者により不定なので、医用電気機器の起動シーケンスは、どちらが先に起動しても対応できるようにするため、複雑となっていた。本発明では、医用電気機器本体よりも制御器が必ず先行してオンすることが保証されるので、医用電気機器の起動シーケンスの設計がシンプルになる。
以下、本発明にかかる医用電気機器の例として、X線照射装置の実施の形態について、図面を参照しながら説明する。
本発明にかかる医用電気機器の別の実施形態について、先に説明した実施の形態と異なる部分を中心に説明する。本実施の形態は、制御器2のUSB供給電流では電磁開閉器の操作コイルを直接駆動するには不十分な場合で、第2リレー素子が交流電源および起動用補助電源間の導通を制御する点において、先に説明した実施の形態と異なる。なお、以降の説明において、第1の実施形態と同様の構成については同一の符号を付した。
本発明にかかる医用電気機器の別の実施形態について、先に説明した実施の形態と異なる部分を中心に説明する。本実施の形態は、医用電気機器本体の電源制御端子と制御器を接続するケーブルが直列にスイッチが設けられている点において、先に説明した実施の形態と異なる。なお、以降の説明において、第1の実施形態と同様の構成については同一の符号を付した。
