る。BEST MODE FOR CARRYING OUT THE INVENTION Embodiments and examples of the present invention will be described below with reference to the drawings. The lower side of the reinforced milky white translucent acrylic thin plate 1 having a thickness of 1 mm to 2 mm, which serves as an image projecting portion on the upper portion, has a thickness of 1 mm to 2
The transparent acrylic thin plate 2 having a thickness of 5 mm is closely supported, and the milky white translucent acrylic thin plate 1 and the transparent acrylic thin plate 2 are sandwiched between outer transparent acrylic plates 3 and 3 having a thickness of 5 mm to 10 mm. A dressing plate a is configured. That is, in the upper part, the outer transparent acrylic plates 3 and 3 on the front and back,
It is composed of three layers of a strengthened milky white translucent acrylic thin plate 1 which is an intermediate layer sandwiched by the outer transparent acrylic plates 3, 3.
Furthermore, in the lower part, the outer transparent acrylic plates 3 and 3 on the front and back
And the transparent acrylic thin plate 2 which is an intermediate layer sandwiched between the outer transparent acrylic plates 3 and 3.
Therefore, the holding plate a is a strong holding plate a as a whole. Therefore, the upper part of the sandwich plate a is a milky white translucent acrylic thin plate 1, and the screen composed of the transparent acrylic plates 3 and 3 can be effectively used as a rear screen.

から投射画像が浮き上がって見える。The image projecting portion is an area of the upper portion of the strengthened milky white translucent acrylic thin plate 1 having a thickness of 1 mm to 2 mm, and when an image is projected in this area, irregular reflection is caused by the thick transparent plates of the outer transparent acrylic plates 3, 3. As a result, the image is projected brightly and the projected image appears to float because the lower part of the image projection portion is a transparent body.

に移動できる。According to the frameless screen of the first aspect, the lower side of the reinforced milky white translucent acrylic thin plate serving as an image projecting portion is closely supported by the upper side of the transparent acrylic thin plate, and is transparent to the milky white translucent acrylic thin plate. The entire surface of the acrylic plate and the thin plate is sandwiched between the outer transparent acrylic plates to form a sandwich plate, and the outer peripheral edge of the lower side of the sandwich plate is supported by the support legs. It has a convenient weight. Further, since there is no frame plate around the projected image portion and the lower part is a transparent body, when the image is projected on the reinforced milky white translucent acrylic thin plate which is the image projecting portion of the present invention, the projected image Because it appears to float, viewers can see it with a feeling of liberation rather than viewing it on a conventional framed screen. Moreover,
Since the reinforced milky white translucent acrylic thin plate which is the image projecting portion is sandwiched between the outer transparent acrylic plates at that portion and has a large thickness, there is an effect that the image becomes bright due to irregular reflection of light. In the frameless screen of claim 2, since the thickness of the reinforced milky white translucent acrylic thin plate is 1 mm to 2 mm, and the thickness of the transparent acrylic thin plate is 5 mm to 10 mm, it is lightweight as a whole, A frameless screen that is convenient to handle and inexpensive can be provided. Claim 3
The frameless screen has multiple casters attached to each support leg, so it can be easily moved in any direction.
