Abstract
An omnidirectional endoscope deviceis provided at a distal end part of an insertion sectionof an endoscopewith an omnidirectional light receiving unitfor receiving an incident light from all around the periphery in the peripheral direction and reflecting the light toward a relay lens optical system. The insertion sectionslidably pierces through a retaining cylinder. A light guide(illumination light transmitting means) is embedded in the retaining cylinder, and an outgoing surface at the distal end of this light guideis faced with a distal end face of the retaining cylinder. The retaining cylindercan be operated in a sliding manner by a gripdisposed at the basal end. By this, the illumination light can strike upon the view field of the omnidirectional light receiving mechanism regardless whether the inside space of an image to be observed is large or small.
