Three objective lenses (11) having optical axes (L) oriented to different directions are mounted on a head section (10) of an endoscope device. Each objective lens (11) has a predetermined viewing field angle .theta. with an optical axis (L) as the center. Each objective lens (11) is provided such that the peripheral section of the viewing field of the lens overlaps with the peripheral section of the viewing field of another adjacent objective lens (11). This causes the head section (10) as a whole has a viewing field angle .phi. that is wider than the viewing field angle .theta. of an objective lens (11) and is unbroken. Each optical image of a portion to be inspected captured by the viewing field angle .phi. is imaged by an imaging element.
?Trois lentilles d'objectif (11) dont les axes optiques (L) sont orientls dans des directions différentes sont montées dans la partie de tête d'un dispositif à endoscope. Chacune des lentilles d'objectif (11) possède un angle de champ .theta. prédéterminé avec un axe optique (L) comme centre. Chacune d'elles (11) est ainsi conçue que la zone périphérique de l'angle de champ chevauche la partie périphérique de l'angle de champ d'une lentille (11) adjacente. Par voie de conséquence, la partie de tête (10) possède globalement un angle de champ ? plus large que l'angle de champ .theta. d'une lentille (11) , sans interruption. Chacune des images optiques d'une zone à inspecter qui est saisie dans l'angle de champ ? est représentée par un élément imageur.
