- 기능 액적을 토출하는 복수의 토출 노즐을 갖는 액적 토출 헤드를 탑재한 헤드 유닛을 구비하고, 워크에 대하여 이 헤드 유닛을 상대 이동시키면서 상기 액적 토출 헤드의 상기 각 토출 노즐로부터 워크를 향하여 기능 액적을 토출하는 묘화 작업을 행함과 함께,발광 소자와 수광 소자를 가지며, 이들 두 소자 간의 광로(光路)를 기능 액적이 가로 질렀을 때의 수광량의 변화에 기초하여 기능 액적의 토출을 검출하는 액적 검출 수단을 설치하고,묘화 작업을 행하기 전에, 상기 액적 검출 수단을 이용하여 상기 각 토출 노즐로부터 기능 액적이 정상적으로 토출되고 있는지의 여부를 판별하는 기능 액적의 토출 확인 작업을 행하도록 한 묘화 장치에서의 노즐의 이상 판별 방법에 있어서,상기 토출 확인 작업에서 어느 하나의 토출 노즐로부터의 기능 액적의 토출이 비정상으로 판별되었을 때에는 다시 상기 토출 확인 작업을 행하고, 이 토출 확인 작업에서도 동일한 토출 노즐로부터의 기능 액적의 토출이 비정상으로 판별되었을 때에, 이 토출 노즐이 이상이 있다고 판정하는 것을 특징으로 하는 묘화 장치에서의 노즐의 이상 판별 방법.
- 제 1 항에 있어서,어느 하나의 토출 노즐이 이상이 있다고 판정되었을 때에는, 기능 액적이 정상적으로 토출되도록 토출 노즐을 회복시키기 위한 메인티넌스 작업을 행하고, 이 메인티넌스 작업 후에 다시 상기 토출 확인 작업을 행하여, 이 토출 확인 작업에서 모든 토출 노즐로부터 기능 액적이 정상적으로 토출되고 있다고 판별되었을 때 상기 묘화작업으로 이행하는 것을 특징으로 하는 묘화 장치에서의 노즐의 이상 판별 방법.
- 제 2 항에 있어서,상기 메인티넌스 작업은 상기 토출 노즐로부터 기능 액적을 토출하는 예비 토출 작업인 것을 특징으로 하는 묘화 장치에서의 노즐의 이상 판별 방법.
- 제 3 항에 있어서,상기 메인티넌스 작업 후의 상기 토출 확인 작업에서도 기능 액적의 토출이 비정상으로 판별되었을 때에는, 상기 토출 노즐로부터 기능 액적을 흡인 제거하는 제 2 메인티넌스 작업을 행한 후에 다시 상기 토출 확인 작업을 행하고, 이 토출 확인 작업에서도 기능 액적의 토출이 비정상으로 판별되었을 때에, 상기 헤드 유닛의 교환 지령을 내리는 것을 특징으로 하는 묘화 장치에서의 노즐의 이상 판별 방법.
- 제 1 항에 기재된 묘화 장치에서의 노즐의 이상 판별 방법을 실시하는 것을 특징으로 하는 묘화 장치.
- 제 5 항에 기재된 묘화 장치를 이용하여, 상기 액적 토출 헤드로부터 워크 상에 기능 액적을 토출하여 성막부(成膜部)를 형성한 것을 특징으로 하는 전기 광학 장치.
- 제 5 항에 기재된 묘화 장치를 이용하여, 상기 액적 토출 헤드로부터 워크 상에 기능 액적을 토출하여 성막부를 형성하는 것을 특징으로 하는 전기 광학 장치의 제조 방법.
- 제 6 항에 기재된 전기 광학 장치 또는 제 7 항에 기재된 전기 광학 장치의 제조 방법에 의해 제조한 전기 광학 장치를 탑재한 것을 특징으로 하는 전자 기기.
