Description
なお、図1は、画像投射装置100をその長手方向が上下に延びる(第2のミラー3が上側に、光源ランプ1が下側に配置される)縦置き状態(第2の設置状態)で使用される様子を示している。この場合、図示はしないが、排気ファン6からの排気をスムーズに行わせるためのラック等の設置台を使用したり、排気ファン6からの排気を側方に導くダクトを設けたりするとよい。 Note that FIG. 1 illustrates the image projection apparatus 100 in a vertically installed state (second installation state) in which the longitudinal direction extends vertically (the second mirror 3 is disposed on the upper side and the light source lamp 1 is disposed on the lower side ) . It shows how it is used. In this case, although not shown, it is preferable to use an installation table such as a rack for smoothly exhausting the exhaust from the exhaust fan 6 or to provide a duct for guiding the exhaust from the exhaust fan 6 to the side.
図4には、図1に示す画像投射装置100がその長手方向が左右に延びる横置き状態(第1の設置状態)で使用される様子を示す。 FIG. 4 shows a state in which the image projection apparatus 100 shown in FIG. 1 is used in a horizontal state (first installation state) in which the longitudinal direction extends left and right.
