Claims (7)
- 피검사자의 눈(E)의 시기능을 자각적으로 검사하는 검안 장치로서,눈(E)앞에 배치되고, 눈(E)에 프리즘 도수를 부여하는 회전 프리즘(136a, 136b);펄스 모터(181, 184)와, 상기 펄스 모터의 회전을 상기 회전 프리즘으로 전달하는 회전 전달 기구(146, 147, 176, 176a, 177, 177a, 178, 179, 183, 186),를 구비하고, 상기 눈(E)에 부여되는 프리즘 도수가 변화하도록 상기 회전 프리즘을 회전시키는 회전 수단;상기 회전 프리즘의 회전 개시 및 회전 정지의 지령 신호를 입력하는 지령 수단(43a, 43b); 및회전 개시의 지령 신호가 입력된 후, 회전 정지의 지령 신호가 입력되기까지, 눈(E)에 부여될 프리즘 도수가 천천히 변화하도록 0.1 ~ 1.0 프리즘/초로 프리즘 도수의 속도로 변화해서 5~100 펄스/초 이상의 속도로 상기 펄스 모터를 회전 구동하기 위한 제어 수단(60, 107, 108);를 포함하고눈(E)에 부여될 프리즘 도수가 천천히 변화하도록 프리즘 도수의 변화 스텝을 0.05 프리즘 이하로 해서 상기 펄스 모터의 회전 스텝 각도에 관하여 상기 회전 프리즘의 회전 스텝 각도를 줄이도록 상기 회전 전달기구는 상기 펄스 모터의 회전을 감속하면서 상기 펄스 모터의 회전을 상기 회전 프리즘으로 전달하는, 예정된 속도 감속비를 가지는 기어 기구(182, 185)를 포함하는 것을 특징으로 하는 검안 장치.
- 제 1 항에 있어서,프리즘 도수의 변화 속도를 0.1 ~ 1.0 프리즘/초의 범위로 설정하는 설정 수단을 더 포함하는 검안 장치.
- 제 1 항에 있어서,눈(E)에 부여하는 프리즘 도수를 지정하는 지정 수단을 더 포함하고,상기 제어 수단은, 상기 지정 수단에 의해 지정 신호가 입력된 때, 지정된 프리즘 도수로 하기 위하여, 0.1 ~ 1.0 프리즘/초 보다 빠른 속도로 프리즘 도수가 변화하도록, 상기 펄스 모터를 구동하는 검안 장치.
