ENDOSCOPE DEVICE FOR DISPLAYING DATA RELATED TO IMAGE ON THE SAME MONITOR SCREEN

摘要

PURPOSE:To display the image from an image guide on a desired part of a monitor without an electric converting circuit or the like by coupling a focusing lens to an image pickup device while shifting their optical axes from each other and using a mount which focuses the image from the image guide with a part off the center of a scan area as the center. CONSTITUTION:An image guide 10 and a light guide 11 are inserted into an endoscope cylinder 1, and an illuminating light source 12 is arranged in one end of the light guide 11. The image of a part illuminated with the light led into a human body through the light guide 11 is led through the image guide 10. The image formed on the exit end face of the image guide 10 passes a lens 10a provided on the exit end face of the image guide 10 and is focused on the image pickup face of a television camera 4 by a focusing lens 2. The center of the outside diameter screw of an eccentric screw mount 30 is shifted from the optical axis of a focusing optical system, which is supported on this mount, by a length (d). Thus, the optical axis of the focusing lens 2 is moved if the eccentric screw mount 30 is screwed into the television camera 4.
