Endoscope for optically variable power using moving time as position information |
摘要 |
A movable lens is provided at the tip of an electroscope, and an optically enlarged image can be observed by moving the movable lens by a motor. A microcomputer measures the entire moving time from a far end to a near end of the movable lens, and the moving time is used as the variable power position information about the movable lens. The variable power position information is displayed by a meter display, etc. on a monitor. Thus, and encoder, etc. is not required.
