Abstract

A body cavity-observing apparatus includes an endoscope with an imaging optical system on the front edge thereof, a prism movably mounted on the forefront of the imaging optical system, and an actuator to drive the prism on a given command signal. A different endoscope image is obtained by moving the prism, and thus, a wide range endoscope image can be easily obtained.
