Title (EN) IMAGE PROJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION D'IMAGES
(JA) 画像投影装置
Abstract:
(EN) [Problem] To provide an image projection device capable of efficiently cooling the inside of a housing thereof. [Solution] Provided is an image projection device that is a short throw projector including a short throw lens serving as a projection lens for projecting an image onto a projection plane, and includes: an optical system unit comprising optical system components including the projection lens; an inlet port, which is provided on the rear surface of the housing that stores the optical system unit, and through which air flows into the housing; an exhaust port, which is provided on the front surface of the housing, and through which the air inside the housing is discharged; and one or more cooling fans provided at the rear surface side of a heat generating component among the optical system components inside the housing.
(FR) Le problème décrit par la présente invention est de fournir un dispositif de projection d'images apte à refroidir efficacement l'intérieur d'un boîtier de ce dernier. La solution de l'invention porte sur un dispositif de projection d'images qui est un projecteur à courte focale comportant une lentille à courte focale servant de lentille de projection en vue de projeter une image sur un plan de projection, et comportant : une unité de système optique comprenant des composants de système optique comportant la lentille de projection ; un orifice d'entrée, qui est disposé sur la surface arrière du boîtier qui loge l'unité de système optique, et à travers lequel de l'air s'écoule dans le boîtier ; un orifice d'échappement, qui est disposé sur la surface avant du boîtier, et à travers lequel l'air à l'intérieur du boîtier est évacué ; et un ou plusieurs ventilateurs de refroidissement disposés sur le côté de surface arrière d'un composant générant de la chaleur parmi les composants de système optique à l'intérieur du boîtier.
(JA) 【課題】筐体内部を効率よく冷却することが可能な画像投影装置を提供する。 【解決手段】画像を投射面に投影する投射レンズとして短焦点レンズを有する短焦点プロジェクターであり、投射レンズを含む光学系部品からなる光学系ユニットと、光学系ユニットを収容する筐体の背面に設けられ、筐体内部に空気が流入される吸気口と、筐体の前面に設けられ、筐体内部の空気が排出される排気口と、筐体内部において光学系部品のうち発熱する発熱部品より背面側に設けられた1または複数の冷却ファンと、を備える、画像投影装置が提供される。
