Embodiment Construction

[0038] Hereinafter, the structure of the projector in the embodiment will be described with reference to the drawings.

[0039] Figure 1 to Figure 7 It shows a projector in a state where an external cabinet is omitted. figure 1 It is a three-dimensional view of the appearance of the projector, figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 as well as Figure 7 They are top view, bottom view, right view, left view, front view and rear view of the projector. In addition, in Figure 2 to Figure 7 In , the projector is shown in a state where the main substrate 40 is detached. In addition, in Figure 8 as well as Figure 9 In , an external perspective view and a cross-sectional view (schematic diagram) of the projection optical system are respectively shown.

[0040] refer to Figure 1 to Figure 7 , The projector has an optical engine 10 , a projection optical system 20 , a power supply unit 30 , a main board 40 , an AV terminal unit 50 , an intake fan 60 , an...

Abstract

The present invention provides a holding structure which realizes the firm holding of the hold object on the exterior casing. The plate-shaped parts (202a and 205a) are retained between the dummy club (80a) from the casing (1a) of the upper side and the dummy club (80b) from the casing (1b) of the bottom side through a bush (80c), thereby, the projection optical system (20) is installed in the casing. The projection optical system (20) is held with a tridimensional mechanism through the whole casing. Thereby, the projection optical system (20) can be firmly held in the casing.

Description

technical field [0001] The present invention relates to a holding structure for holding an object to be held in an external cabinet formed by combining a first cabinet and a second cabinet. Also, the present invention relates to a projection display device that enlarges and projects an image on a display element onto a projected surface. Background technique [0002] Projection display devices (hereinafter referred to as “projectors”) that enlarge and project an image on a display element (liquid crystal panel, etc.) onto a projected surface (screen, etc.) have been commercialized and widely used. Among such projectors, in order to shorten the distance between the screen and the main body of the projector, a projector with an oblique projection structure has been proposed, that is, while widening the angle of the projection optical system, it also makes the traveling direction of the projected light relatively opposite. The optical axis of the projection optical system is t...
