ABSTRACT:
An omnidirectional endoscope device1is provided at a distal end part of an insertion section12of an endoscope10with an omnidirectional light receiving unit20for receiving an incident light from all around the periphery in the peripheral direction and reflecting the light toward a relay lens optical system13. The insertion section12slidably pierces through a retaining cylinder33. A light guide35(illumination light transmitting means) is embedded in the retaining cylinder33, and an outgoing surface at the distal end of this light guide35is faced with a distal end face of the retaining cylinder33. The retaining cylinder33can be operated in a sliding manner by a grip31disposed 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.
