Abstract
Disclosed is an image observation system which employs a bellows expanded and contracted by fluid pressure to move an optical element, such as an image pick-up lens, within an image pick-up adapter. The bellows, which is operatively associated with the optical element, is communicated with a manually operated fluid pressure drive unit by a fluid pressure transfer pipe. Manipulating the drive unit forces a fluid into or withdraws a fluid from the bellows via the transfer pipe to expand or contract the bellows, thereby controlling the position or attitude of the optical element located at the end of an image fiber.
