Example Embodiment

[0041] (Schematic structure of the screen)

[0042] Hereinafter, an embodiment of the present invention will be explained based on the drawings.

[0043] 1 and 2 are perspective views showing the schematic structure of the screen 1. Specifically, FIG. 1 is a perspective view of the screen 1 viewed from the front side where image light enters. FIG. 2 is a perspective view of the screen 1 viewed from the back side.

[0044] In addition, "left" and "right" described below mean left and right when viewed from the back side of the screen 1.

[0045] The screen 1 projects, for example, image light enlarged and projected from a projector or the like. This screen 1, as shown in Fig. 1 or Fig. 2, roughly includes an image projection unit 1A, a supporting leg 1B, and a binding member 1C (refer to Figure 13 ).

[0046] (Structure of image projection unit)

[0047] The image projection unit 1A is a part for projecting image light, and as shown in FIG. 1 or FIG. 2, it includes a screen main body

Abstract

The invention relates to a screen which simplifies the structure and has excellent use performance. The screen (1) comprises a retention member (5) for retaining a first storage member (3) and a second storage member (4). The retention member (5) comprises a column (51) substantially vertical to the direction opposite to the first storage member (3) and the second storage member (4), extending along screen body; a pair of pole modules (53), respectively connected with a column (51) and the first storage member (3) and the second storage member (4). One end of each of the pair of pole modules (53) is respectively rotatably coupled to the first storage member (3) and the second storage member (4) and another end of each is rotatably coupled to the column (51).
