Patent attributes
When a front cover 12 in which an inner grille 13 is fitted is mounted to the body of the projector, a fin member 13b formed as one unit with the inner grille 13 is placed with very little clearance between itself and a partition 33 separating the region where a light source device 20 is provided from the region where an optical system 100 is provided. Therefore, hot air of a first fan can be prevented from passing between the partition 33 and the front cover 12 and entering the region where the optical system 100 is provided. As a result, it becomes possible to prevent the hot air from entering the above region and further entering the optical system 100 or entering the optical path of a projection lens 26 to cause a heat-wave effect, thus the projector is capable of suppressing a heat-wave effect.
