Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a movable stage device that can be freely stored on a wall and deployed on a floor, and used in gymnasiums, community centers, assembly halls, schools, kindergartens, etc. , if it is installed later in a room without a stage, such as a classroom or play room in a nursery school, or if it is installed in advance in a room that does not have a built-in fixed stage, such as an auditorium or theater. It is suitable.

(Prior art) Conventionally, as a unique folding stage device,
As shown in the device described in Japanese Utility Model Publication No. 18628, the stage body is raised and lowered using a weight and a winch mechanism, so that it can be stored leaning against a wall and unfolded on the floor. This is the beginning, and from then on, the idea is pushed forward step by step,
The present inventor has published Japanese Unexamined Patent Publication No. 52-6252, Utility Model Application No. 52-6252,

-Proposed various stage devices shown in Publication No. 787 and Publication of Utility Model Application No. 11800, etc., among which,
- In the case of the stage device shown in Publication No. 11800,
A simple stage device that can be stored on a wall and can be deployed on the floor has recently been put into practical use by balancing the stage body with a weight. The main body is available in two types: a high-floor type with foldable stage legs, and a low-floor type with fixed stage legs of a short length, and has become well-received.

(Problem to be solved by the invention) However, in the case of such a stage device, when compared with a built-in fixed stage in an auditorium or theater, it does not have a stage frame like a proscenium arch, so it cannot be used as a stage. It is difficult to obtain a profound feeling, and since there is no sleeve section of the stage, the backstage area is completely visible to the audience, so the sleeve section must be enclosed with a separate screen or the like. Therefore, in order to solve the above-mentioned problems, the present inventor proposed Japanese Patent Application No. 120395/1983
