ENDOSCOPE
First Claim
1. An endoscope comprising:
- an insertion portion to be inserted into a living body;
a low magnification observation system for performing low magnification observation at a region to be observed in the living body, the low magnification observation system being provided to the insertion portion;
a high magnification observation system for performing high magnification observation at a region of interest which is a local region of the region to be observed, the high magnification observation system being provided to the insertion portion;
wherein the high magnification observation system includes a plurality of illumination portions for respectively illuminating illumination lights for high magnification observation with respect to the region of interest, and the plurality of illumination portions are respectively arranged at predetermined positions on a distal end surface of the insertion portion.

Abstract
There is provided an endoscope capable of observing cells at a desired position existing in the depth direction with a simple structure as compared to the conventional configuration. The endoscope includes an insert unit to be inserted into a biological body, a low-scaling observation system for observing an observation position in a biological body with a low scaling, and a high-scaling observation system for observing a target position of the aforementioned observation position as a local position with a high scaling. The high-scaling observation system includes a plurality of illumination units for applying illumination light for high-scaling observation of the target position. The illumination units are arranged at predetermined positions of the end face of the insert unit.
