Abstract
【解決手段】液量検出ユニット(1)は、フィラを含まない透明な液体樹脂(L3)を溜めるタンク(2)と、透過型センサ(3、4)とを備える。透過型センサは、測定光を投光する投光部(30、40)と、測定光を受光する受光部(31、41)と、受光部が測定光を受光するか否かによって液体樹脂が所定量以下になったことを判断する判断部(5)とを有する。投光部と受光部とは直線上に対向配置される。判断部は、液体樹脂と空気とによって屈折又は反射する測定光を受光部が受光するか否かによって液体樹脂の液量を検出する。

- 透過型センサを用いて透明容器に溜められた透明液体の液量を検出する液量検出ユニットであって、
該透過型センサは、測定光を投光する投光部と、該投光部が投光する該測定光を受光する受光部と、該受光部が該測定光を受光するか否かによって透明液体が所定量以下になったことを判断する判断部と、を備え、
投光部と該受光部とを直線上に配置させ、透明液体と空気とで該測定光が屈折および反射して該受光部が該測定光を受光するか否かによって透明液体が所定量以下になったことを該判断部が判断することを特徴とする液量検出ユニット。 - 該投光部と該受光部とを結ぶ直線が透明液体の液面に対して斜めに傾斜していて、
該透明液体の液面で該測定光が屈折および反射して該受光部が該測定光を受光するか否かによって透明液体が所定量以下になったことを該判断部が判断する請求項1記載の液量検出ユニット。 - 透明容器内に間隔を空けて円筒を2つ立設させ、該2つの円筒に該投光部と該受光部とを別々に配設させ、
該投光部と該受光部とを結ぶ直線は該2つの円筒の中心をずらして配置させ、
該円筒の内側と外側となる空気と透明液体とで該測定光が屈折および反射して該受光部が該測定光を受光するか否かによって透明液体が所定量以下になったことを該判断部が判断する請求項1記載の液量検出ユニット。
