When used as a portable device, a pair of left and right stabilizing legs (7) for making the developed screen (4) stand alone is provided rotatably in the horizontal direction. As shown in FIG. 3, the two stable legs (7) have a use position (7A) facing forward and backward, and a use position (7A).
(7A), it can be rotated by about 90 degrees to the non-use position (7B) facing in the left-right direction.

The cabinet body (2) includes a pair of left and right side plates (8), and a rear plate that covers a rear surface and a bottom surface between both side plates (8).
(9), and a bottom plate (10), both side plates (8) and a rear plate
(9) supports the top plate (11).

The top plate (11) has a horizontally elongated screen (4) for projecting the expanded screen (4) and the frame (5) upward when the screen device (1) built in the cabinet body (2) is used. Opening (12) is provided.

The opening (12) has an opening / closing lid supported on a top plate (11) with a pair of left and right hinges (13) rotatable about a horizontal axis.
It is opened and closed by (14).

On the front surface of the cabinet body (2), a pair of left and right doors (15) of a shutter type is provided, and both doors (15) extend along the left and right side plates (8) and the rear plate (9). It is slidably supported between the bottom plate (10) and the top plate (11) so that it can slide.

At the four corners of the bottom plate (10), a cabinet body
A caster (16) for facilitating the movement of (2) is provided.

The front plate (17) and the rear plate (1) of the cabinet body (2)
8), a pair of left and right receiving plates (19) pointing in the front-rear direction and supporting both sides of the case body (3) of the screen device (1).
Are provided at predetermined intervals in the left-right direction.

As will be described later, between the left and right inner plates (20) and (20) provided adjacent to the inside of the left and right side plates (8), the stable legs ( A pair of long front and rear engagement plates (21) and (21) are provided in the left-right direction, which can be disengaged from 7).

The engagement plates (21) are disposed slightly above the upper surface of the receiving plate (19), and are separated from each other in the front-rear direction.

The inside of the cabinet body (2) includes receiving plates (19) and (19).
The screen device (1) is built in the upper partition (22), and the projection device and related equipment are built in the lower partition (23). Or other items are stored.

The upper partition (2) is located between the engagement plates (21) and (21).
A gap (24) is formed to pass through the lower section (2) and the lower section (23). The front and rear width of the gap (24) is such that the case body (3) of the screen device (1) can be inserted. Stipulated.

In this screen device (1), the case main body (3) is fitted into the gap (24) between the engagement plates (21), (21), and both right and left ends thereof are provided on both receiving plates (19). The upper end of the stabilizer leg (7) sneaks into the lower surface of the engagement plate (21) by being placed on the upper surface and rotating the stabilizer leg (7) from the non-use position to the use position. (21), thereby preventing upward movement of the case body (3).

By fitting the case body (3) into the gap (24) between the engaging plates (21) and (21), the engaging plates (21) and (21) contact the front and rear portions of the case body (3). Touch and screen device (1)
Can be positioned in the front-rear direction, and can be easily installed at a regular position.

When the stabilizer leg (7) is engaged with the lower surface of the engagement plate (21), the screen device (1) is rattled during use.
And fall is prevented. In addition, by setting the stabilizing leg (7) to the unused position, the stabilizing leg (7) is detached from the engaging plate (21), and the screen device (1) can be taken out of the cabinet body (2).

The screen device (1) is connected to the cabinet body
When the screen device (1) is not used in the state where the screen device (1) is built in the (2), as shown in FIGS. 1, 3, and 4, the screen device (1) is folded and the opening (12) is opened. ) Is closed by a lid (14). In this state, the screen device (1) is not exposed to the outside of the cabinet body (2) at all, so that the interior can be improved.

When it is desired to use the screen device (1), as shown in FIG. 2 and FIG.
Screen (4) and frame (5) of screen device (1)
Is pulled out from the case body (3) through the opening (12) to be in a deployed state.

The caster (16) is mounted on the cabinet body (2).
Is provided, it is possible to easily move the screen device (2) together with the cabinet body (2) to an arbitrary projection place.

When the screen device (1) is used alone in another place, the stabilizer (7) is rotated from the use position to the non-use position, and the screen device (1) is opened. Through the cabinet body (2) together with the case body (3).

In this state, the screen device (1) becomes an original portable device and can be freely carried. In use, the stabilizing leg (7) is rotated to a use position to be used on a floor surface or a table. , The case body (3) is opened, the screen (4) and the frame (5) are pulled out from the inside, and the screen (4) is developed. At this time, the stabilizing leg (7) exerts its original function of making the screen (4) independent.

At the time of installation in the cabinet (2), the upper surface of the stabilizing leg (7) is used to prevent the stabilizing leg (7) from coming off from the opening (12) and to prevent the developed screen (4) from tilting in the front-rear direction. We are trying to prevent it.

In the illustrated embodiment, the screen device (1)
Although such a portable device is used, the case body (3) and the like are omitted, and the screen device (1) is of an installation type, or the screen device (1) is a pandagraph type. Another type of folding type without using the frame (5) can be adopted.

[0035]

According to the present invention, the following effects can be obtained. According to the first aspect of the present invention, when the screen is not used, the screen can be folded and stored in the interior of the cabinet in a beautiful manner. It is suitable for use in a conference room or the like.

Further, the screen device can be moved to the projection place together with the cabinet body, and the interior of the room can be improved without harmony of the meeting room at the projection place.

According to the second aspect of the present invention, since the portable screen device is used, the entire screen device can be taken out of the cabinet and freely carried, and the screen can be developed and projected at another place. Can be used for

At this time, it is convenient that the stabilizing legs for allowing the developed screen to stand on its own can be used to prevent the screen device from coming off when the screen device is incorporated in the cabinet and to prevent the developed screen from falling in the front-rear direction.

That is, since the stabilizing legs provided on the case body of the screen device are engaged with the engaging plates, the screen device is easily and securely fixed in the cabinet body without providing any special fixing means or the like on the screen device. Can,
It is possible to prevent rattling and falling. Further, by removing the stabilizing legs from the engagement plate, the screen device can be easily taken out of the cabinet main body and can be used for portable use.

According to the third aspect of the present invention, the case body of the screen device is inserted into the gap between the two engagement plates, so that the screen device can be positioned and easily installed at a regular position.

According to the fourth aspect of the present invention, the stabilizing legs of the screen device can be easily operated to any position from the lower section of the cabinet body.

According to the fifth aspect of the present invention, the cabinet main body can be easily moved to an arbitrary projection place.
