Patent ID: 6887196

Claim:
An omnidirectional endoscope device having a view field covering all around the periphery in the peripheral direction, comprising a main body section; an insertion section extending from said main body section; an omnidirectional light receiving mechanism disposed at a distal end part of said insertion section and for receiving an incident light coming from the entire periphery at the same time in the peripheral direction and reflecting it towards a basal end; image transmitting means for transmitting light coming from said omnidirectional light receiving mechanism; and an illumination light transmitting mechanism; said illumination light transmitting mechanism including illumination light transmitting means extending along said insertion section and for transmitting the illumination light so as to be outputted from a distal end face of said illumination light transmitting means; a retaining part for retaining said illumination light transmitting means, at least a distal end part of which is in the form of a ring, and slidably fitted to an outer periphery of said insertion section; and a slide control part connected to said retaining part and disposed at a basal part of said insertion section or at said main body section and for sliding said retaining part and thus a distal end part of said illumination light transmitting means along said insertion section.
