er Head Projector) is used to magnify and project the image light corresponding to the image showing appropriate data and information on the screen, and present the data and information to the participants of multiple conferences and presentations. Things happen frequently.

For projection onto a screen by such a projection device, the image light projected from the projection device P1 as shown in FIG. 7 is projected from the front side to the screen S1 having light reflectivity. The front projection method of displaying (forming an image) on the screen S1 and the image light projected from the projection device P2 as shown in FIG. 8 are projected from the rear side to the screen S2 having a light transmitting property and displayed (consolidated). There is a rear projection method etc.

[0004]

However, in the front projection method, when a person passes between the screen and the projection device, the projected image light is obstructed and the image is disturbed, and the image is projected on the screen. However, there is a problem that the movement of the screen in front of the screen is restricted when a presentation is made while pointing to a displayed image.

On the other hand, in the rear projection method, it is necessary to separate the projection device from the screen by a distance such that the projection light can form an image on the screen. Therefore, a predetermined space must be secured behind the screen. However, it has a problem that it is difficult to use in a small conference room.

Therefore, when the projection device is positioned on the side of the screen to display an image, a normal projection device does not have a trapezoidal correction function in the width direction.
A proper image cannot be displayed. Further, as a means for solving the above-mentioned inconvenience, although a projection device that has a function of digitally processing the trapezoidal correction in the width direction and enables projection from the side to the screen has been devised, Such a projection device must be newly purchased, which puts a burden on the user.

In order to solve these problems, it is possible to apply an appropriate projection device such as a hand-held projection device, which is suitable for conferences and presentations, and can be used in a narrow space. Provide a partition that functions as and a projection equipment that uses this partition.

With such a screen, by adjusting the relative angle between the reflecting surface and the incident surface, a predetermined projection device such as a projection device that is normally used by the user is applied, and the projection device is adjusted. By arranging it at an appropriate position on the side of the screen element, it becomes possible to display appropriate image light on the screen element. Therefore, it is possible to use the projection device in a narrow space without securing a large space behind the screen having the screen element because of the arrangement of the projection device. In addition, in such a usage mode, since the image light does not pass to the front side of the screen element, that is, the side where the image is to be observed, even if a person moves to the front side of the screen element, the projection onto the screen element is performed. Therefore, it can be suitably used for presentations and meetings.

As a preferred embodiment of changing the relative angle between the reflecting surface and the incident surface with a simple structure, the side edge of the first partition element and the side edge of the second partition element are preferable. And a portion that is rotatably connected in the horizontal direction and the angle formed by the first partition element and the second partition element is changed to change the relative angle between the reflecting surface and the incident surface. What you are doing.

Further, in such a structure, in order to be able to take various usage modes, the first partition element and the second partition element are made to have their reflecting surfaces and incident surfaces facing each other. It is desirable to be configured to be rotatable between a closed state that is adjacent in the depth direction and an open state that is adjacent in the width direction.

The partition of the present invention may be, for example, one mounted on a wall or the like,
In order to have a flexible partition that can be installed in various places, it is preferable to provide a leg portion that supports at least one of the first partition element and the second partition element so as to have self-supporting property. .

The second panel 5 has an incident surface I on which the image light reflected by the reflecting surface R is incident, and a screen member S which is a screen element capable of transmitting and displaying the image light incident on the incident surface I. It is equipped with. In the present embodiment, the second panel 5 is formed by mounting the screen member S over substantially the entire area inside the frame 51 forming the outer shape of the second panel 5, that is, the screen. The member S is configured to be the main body of the second panel 5. Specifically, this screen member S
Is at least light transmissive to a surface of the transparent flat plate such as a glass plate or an acrylic plate fitted in the frame body 5 facing the reflecting surface R in the closed state (E) of the partition 3. It is configured by adhering an appropriate translucent decorative sheet having the above. Then, the incident surface I is formed on the surface on which the translucent decorative sheet is mounted. As the light-transmitting decorative sheet, a sheet having a light diffusing property in order to widen the viewing angle of an image is desirable. In addition, the screen member S has a surface opposite to the incident surface I, that is, a surface on which an image is observed, which can be written with at least a writing instrument such as a pen. On the other hand, the frame body 51 has substantially the same configuration as the frame body 41 of the first panel 4, and has a pair of left and right vertical frame members 511 having a substantially cylindrical shape.

11 is rotatably fixed to the connecting base T1 extending between the upper end portion and the lower end portion thereof by an appropriate means. Alternatively, a hinge may be used.

Next, a case where the partition 3 thus constructed and the projection equipment P using the partition 3 are used in the conference room W shown in FIG. 6 will be described.

First, the partition 3 is set in the conference room W with the second panel 5 positioned on the conference table TB side and the first panel 4 positioned at the back (upper side in the drawing). On the other hand, the projector 1 and the personal computer C are arranged on the movable mounting table 2 on the side of the opening / closing end side of the partition 3.

Next, the projector 1 projects the image light based on the information output from the personal computer C onto the reflecting surface R of the first panel 4. The projector 1 is set to the front projection mode. In this case, the image light advances while spreading corresponding to the projection angle set in the projector 1 with respect to the reflecting surface R, as shown by the imaginary line in FIG. Then, when reflected from the reflection surface R, made incident from the incident surface I of the screen member S, transmitted therethrough and observed from the side opposite to the incident surface I, an image in which the right and left direction is visually recognized correctly is displayed.

After the image is once displayed in this way, the movable mounting table 2 is moved, and the first panel 4 is horizontally rotated to adjust the angle with respect to the second panel 5 and displayed on the screen member S. Adjust the displayed image so that it has the correct shape and has an appropriate size. In the case where there is only one person who installs it, since it is usually located in the vicinity of the movable mounting table 2, the screen member S is kept in a state where it does not obstruct the view.
The image displayed on the screen can be confirmed by the reflection surface R of the mirror M. Further, when it is desired to additionally write something on the image displayed on the screen member S by handwriting, the user should stand in front of the second panel 5 and write on the surface thereof with an appropriate writing instrument such as a pen. In this case, the image is not disturbed even when standing on the front side of the second panel 5 including the screen member S.

The projection equipment P using the partition 3 described above adjusts the image displayed on the screen member S by adjusting the relative angle between the reflecting surface R and the incident surface I of the partition 3 and mounting the projector 1 thereon. By moving the movable mounting table 2 described above, the shape and size of the image displayed on the screen member S can be easily adjusted to correct the distortion. Therefore, the projector 1 is arranged on the side of the screen member S, and The image light can be properly displayed.

Therefore, compared to the conventional rear projection type equipment shown in FIG. 8, it is not necessary to secure a large space in the back of the partition 3 which functions as a screen.

Further, since the image light does not pass to the front side of the screen member S, that is, the side where the image is to be observed, unlike the conventional front projection type equipment shown in FIG. Even if the person moves, the projection on the screen member S is not hindered. Moreover,
Since the surface of the screen member S on which the image is viewed can be written with at least a writing instrument such as a pen, it is possible to write on the image while displaying the image, which is extremely useful for presentations and meetings. It is convenient to do.

Further, since the partition 3 of the present embodiment is constructed by connecting the first panel 4 and the second panel 5 by the connecting device T so as to be rotatable in the horizontal direction, the reflecting surface R is simple in construction. It is possible to change the angle formed between the incident surface I and the incident surface I.

Since the first panel and the second panel can rotate between the closed state (E) adjacent to each other in the depth direction and the open state (F) adjacent to each other in the width direction, The closed state (E) makes it compact when it is put away, and the open state (F) makes it easy to use as a partition and easy to use.

Further, since it is provided with the leg portions 6 to stand by itself, it can be installed in various places.

The present invention is not limited to the above embodiment.

For example, the reflecting element is not limited to one provided over almost the entire area of the first panel 4 which is the first partition element like the mirror M of the present embodiment, and the reflecting surface thereof is a general projector. It may be provided only in the upper portion of the first partition element, for example, as long as it has a size that can correspond to the projection angle of. Similarly, the screen element may be provided only on the upper portion of the second partition element.

Further, as the reflecting element forming the reflecting surface, not only the mirror M of this embodiment but also, for example, a predetermined film on which foil stamp printing of reflective metal or the like is applied, It may be such that the above-mentioned frame is attached to the frame body.

Further, the first partition element is constructed such that a reflector having a reflecting surface is rotatably supported at the upper and lower ends thereof, and the reflecting surface and the first reflecting element are rotated by rotating the reflector. The relative angle between the two partition elements and the incident surface may be changed.

The screen element is not limited to the one using the translucent decorative sheet of this embodiment, but may be a so-called transmissive lens screen including a Fresnel lens and a lenticular lens.

Further, the partition has a leg portion for supporting only one of the first partition element and the second partition element, and the other partition is supported by one panel by the connecting mechanism. It may have any configuration.

The partition may be used by being arranged in the housing.

Further, a partition having a plurality of first partition elements and second partition elements may be used.

Further, the partition of the present invention may be applied to, for example, a display of a store.

In addition, the specific configuration of each unit is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0044]

The present invention is carried out in the form as described above, and has the following effects.

That is, according to the screen of the first aspect of the invention, the relative angle between the reflecting surface and the incident surface is adjusted by applying a predetermined projection device such as the projection device that the user normally uses. By arranging this projection device at an appropriate position on the side of the screen element, it is possible to display appropriate image light on the screen element. Therefore, even if a person moves to the front side of the screen element, the display on the screen element is not hindered and the projector can be used in a narrow space.

According to the projection equipment of the invention of claim 6, in addition to the effect of the screen of the invention of claim 1, the projection device can be moved easily and displayed on the screen element. The image can be adjusted more easily.
