DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to the prior art disclosed in Japanese Patent No. 789, the number of stacking units in the core unit and the number of rows arranged in the core unit are selected for each installation site so that the space of the installation site can be obtained according to the request of the orderer. It has the feature that it can be installed in installation spaces of different sizes. In addition, since core units can be stacked and unloaded, there is a feature that installation and removal can be done in a short time.

However, since the external dimensions of the core unit are fixed, when the core unit is installed in a space with a limited depth, a new reflecting mirror is used to make the light rays of the image from the projection unit approximately 90 degrees with the same optical path length. It is necessary to have a multi-vision system that has a form in which it is bent and projected on a screen and the depth dimension is shortened. Currently, different types of different types are developed, produced, and installed, and it is currently the case that two multi-types with different external shapes are installed. A vision is needed. Therefore, the development cost and development time are doubled for one multi-vision structure.

Also, in a multi-vision system using a reflecting mirror and shortening the depth direction, since the lower end of the projection unit extends to the lower front surface and a screen cannot be arranged, the depth is kept as it is, and it is only possible to stack it in the height direction. There was a drawback that the screen could not be expanded to more than 3 steps.

The present invention has been made in view of the above points,
The purpose is to provide a multi-vision structure having two different outer shapes by adding or removing a reflecting mirror using one structure and changing the surface on which the screen is arranged. An object of the present invention is to provide a structure of a core unit that can be stacked in three or more stages with a core unit having a dimension reduced in the depth direction using a reflecting mirror.

[0007]

In order to achieve the above object, in the present invention, the multivision structure has the following configuration.

[0008] 1. A first screen unit connecting means for detachably connecting the screen unit to the first surface of the frame, and a first projection unit arranged and fixed at a position where the light beam of the image is directly projected on the screen unit. A first state equipped with projection unit coupling means, a second screen unit coupling means for detachably coupling the screen unit to the second surface, and a mirror for reflecting the light beam of the image on the screen unit. The second projection unit coupling means for disposing and fixing the projection unit at a position where the light beam of the image of the projection unit is projected via the mirror, and the reflecting mirror fixing means for detachably fixing the reflecting mirror are provided.

[0009] 2. A means for detachably fixing the projection unit mounted on the first stage and the second stage of the apparatus main body equipped with the projection unit and the reflecting mirror to the central position on the left and right of the apparatus main body and a plurality of positions moved to the left and right. It is provided with means for moving the projection units and the reflecting mirrors mounted on the second stage or more upward and detachably fixing them at a plurality of positions, and each screen is composed of the original screen and the screen frame. A second set of screen units in which the area of the first set of screen units was increased stepwise was fixed to the apparatus body.

3. The apparatus main body including the projection unit of the third stage of the apparatus main body, or the projection unit of the third stage and the fourth stage and the reflecting mirror, was stacked upside down with respect to the projection unit of the first stage or the second stage.

[0011]

[Action]

1. The gantry has a first state in which the screen unit is connected to the first surface and a screen unit in which the screen unit is connected to a second surface different from the first surface, and the light beam of the image of the projection unit is transmitted through the reflecting mirror. Since it has a second state of copying, it is possible to obtain two states with different outer shapes by changing the vertical and depth dimensions with one gantry.

2. The projection units mounted in the first and second stages of the device body can be fixed to the center of the device body and in a plurality of positions moved to the left and right, and the projection units and the reflection mirrors mounted in the second stage and above can be fixed. Since it can be moved upward, the set of the first screen unit consisting of each screen and the screen frame and the set of the second screen unit whose area is gradually increased are the same main unit. Can be exchangeably fixed.

3. Depth dimension as it is stacked upside down with respect to the 1st stage or 2nd stage projection unit with the 3rd stage of the device body, or the 3rd and 4th stage projection units and reflector It is possible to realize a multi-vision that can expand the screen of three-tiered or four-tiered by keeping the above.
