Title
(EN) PROJECTION LENS AND PROJECTION DEVICE
(FR) LENTILLE DE PROJECTION ET DISPOSITIF DE PROJECTION
(JA) 投射レンズ及び投射装置
Abstract
(EN)
A projection lens that is to be attached to a case of a projection device that has an electro-optical element. The projection lens comprises an optical system through which light passes, a second holding part that rotates relative to the case, a third holding part that rotates relative to the second holding part, an electrical drive part that electrically controls the rotation of the second holding part relative to the case, the rotation of the third holding part relative to the second holding part, or the drive of the optical system, and a cover part that covers the electrical drive part. Light that has a second optical axis passes through the second holding part, and light that has a third optical axis that bends from the second optical axis passes through the third holding part.

L'invention concerne une lentille de projection destinée à être fixée au boîtier d'un dispositif de projection qui est doté d'un élément électro-optique. La lentille de projection comporte un système optique à travers lequel passe une lumière, une deuxième partie de maintien qui tourne par rapport au boîtier, une troisième partie de maintien qui tourne par rapport à la deuxième partie de maintien, une partie d'entraînement électrique qui commande électriquement la rotation de la deuxième partie de maintien par rapport au boîtier, la rotation de la troisième partie de maintien par rapport à la deuxième partie de maintien, ou l'entraînement du système optique, et une partie de couvercle qui recouvre la partie d'entraînement électrique. La lumière présentant un deuxième axe optique traverse la deuxième partie de maintien, et la lumière présentant un troisième axe optique qui est coudé par rapport au deuxième axe optique traverse la troisième partie de maintien.
