Abstract
A portable endoscope system has an illuminating light guide for transmitting light for illuminating an object. The light guide has an entrance end portion disposed in an endoscope control part. A light source lamp is contained in an illuminating light supply unit for supplying illuminating light to the light guide. A filament serving as a light emission source in the lamp is disposed such that the longitudinal direction of the filament is approximately perpendicular to an entrance end surface of the light guide. A spheroidal reflecting mirror converges illuminating light emitted from the lamp onto the entrance end surface of the light guide. A bore is provided in a side of the mirror for receiving a head portion of the lamp. A reflecting surface is provided on an inner surface of a rear end portion of the mirror.
