Embodiment approach 1
[0048] Below, refer to Figure 1 to Figure 6 The projection type video display device according to Embodiment 1 of the present invention will be described.
[0049] The projection type image display device according to this embodiment is a three-panel liquid crystal projection type image display device, which includes figure 1 A box-shaped frame body 10 as shown in the external perspective view of . It should be noted that, in the following description, the direction in which the projection-type image display device projects image light from the projection lens 11 is referred to as the front in the front-rear direction. In addition, when the projection-type video display device is installed on a horizontal plane, the direction parallel to the horizontal plane and perpendicular to the front-rear direction is defined as the left-right direction. In addition, the above-mentioned front-back direction, left-right direction, and up-down direction are indicated by arrows in each fi...
Embodiment approach 2
[0100] Next, according to Figure 7 A projection type video display device as an electronic device in Embodiment 2 will be described. In addition, about the same requirement as Embodiment 1, the same code|symbol is attached|subjected to the part described in drawing. In addition, when the components not shown in the second embodiment are described using the same reference numerals as those in the first embodiment, members assigned the same reference numerals are the same as those in the first embodiment.
[0101] On the basis of Embodiment 1, Embodiment 2 changes the configuration of the "mechanism for reducing or eliminating the biting of the brush into the air filter" of the present invention when the brush and the air filter move and reverse relative to each other.
[0102] In this embodiment, on the turned position of the left end of the air filter 23, the air filter 23 is reduced in such a way that the rotating brush 31 does not come into contact with the air filter 23 o...
Embodiment approach 3
[0108] Next, according to Figure 8 A projection type image display device as an electronic device according to Embodiment 3 will be described. In addition, about the same requirement as Embodiment 1, the same code|symbol is attached|subjected to the part described in drawing. In addition, when the components not shown in the third embodiment are described using the same reference numerals as those in the first embodiment, members assigned the same reference numerals are the same as those in the first embodiment.
[0109] On the basis of Embodiment 1 of the present invention, Embodiment 3 changes the configuration of "the mechanism for reducing or eliminating the biting of the brush into the air filter when the brush and the air filter are moved and reversed relative to each other". That is, in Embodiment 3, at the turning position of the left end of the air filter 23 , the distance between the rotating brush 31 and the air filter surface in the direction perpendicular to the...
