とするビデオプロジエクタ。 In a video projector having a liquid-cooled coupling optical unit that seals a cooling liquid between the projection lens and the projection tube, a method for maintaining the relative arrangement of the projection lens and the projection tube in a predetermined optically designed relationship is provided. The first spacer is composed of a single spacer and the second spacer is a two-layer spacer, and requires a plurality of structures.
The single spacer is formed in a shape that can be used commonly in each R, G, B unit and each variation, and the tilting that needs to be different for each R, G, B unit and each variation is formed. A video projector characterized in that the second spacer having a simple shape is configured to perform only the corner setting function.
