Abstract

PROBLEM TO BE SOLVED: To make it possible to obtain a display screen having effective and the maximum size even in a narrow space and provide video having variations by spreading a screen along the viewable surface of wall in a box-shaped housing and providing a projector for projecting the video on the screen while reflecting the video on a reflection mirror. SOLUTION: In a self-running vehicle having a box-shaped housing 1, a sidewall 3 on one side of the box-shaped housing 1 is made viewable by forming the periphery thereof with a constituting material 4 of the housing 1 and the remaining part thereby with transparent material 5 such as acrylic resin. In the internal part of the box-shaped housing 1, a screen 6 is spread along the side wall 3 constituted of a transparent material 5, a reflection mirror 7 is provided on the counter side surface of the screen 6, and the reflection mirror 7 and a projector 8 are arranged so that the video is projected on the screen by reflecting the video light beam of the projector 8 on the reflection mirror 7. Consequently, an inside-out video is projected on the internal side surface 6A of the screen 6, however, the video of the external side surface 6B of the screen 6 which is to be seen from the outside is made to be normally projected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for externally observing an image to be displayed while moving, and more specifically to an advertisement while moving, watching a movie outdoors, an event, and the like. It can be used when a large screen is required.

[0002]

2. Description of the Related Art Conventionally, as a means of advertising while moving, the main method is to draw characters, drawings, etc. on the side of a vehicle which is a moving body, and the contents of the advertisement are specific and do not change (motion). Things. For moving images, large-sized display devices are incorporated into the vehicle to reproduce and reproduce the video on a deck. However, the size of the display is limited, and the larger the device, the higher the cost. It is.

[0003]

SUMMARY OF THE INVENTION The present invention is efficient and has a maximum size even in a small space in view of the fact that the display screen is restricted when moving characters, drawings, etc. are displayed while moving. It is an object of the present invention to obtain a mobile projection device which can provide a display screen of the type described above and can provide a changing image.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a see-through wall is formed on one side of a box-type carrier of a self-propelled vehicle having a box-type carrier. A screen is stretched, a reflecting mirror is installed on the opposite side of the screen, and a projector that reflects an image on the reflecting mirror and projects the image on the screen is provided.

According to the present invention, a screen stretched along the transparent wall surface can be viewed from the transparent wall surface on one side of the box-type carrier, and an image is projected on the screen by a projector. Instead of using a reflector to increase the projection distance to the screen, the image is expanded, and an enlarged image that is at least as long as the width of the loading platform is displayed on the screen.

[0006] The vehicle having the box-type carrier is self-propelled,
The location can be specified or moved freely, and an image that changes freely can be selected. The image on the screen can be changed continuously and selectively while moving.

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an embodiment, and FIG. 2 is a cross-sectional plan view of a box-type carrier.

A self-propelled vehicle 2 having a box-type carrier 1, one side wall 3 of which is surrounded by another box-type carrier 1.
The remaining portion formed of the component material 4 can be seen through the inside with a transparent material 5 such as an acrylic resin. Since the transparent material 5 constitutes a part of the side wall, the material and thickness of the side wall should be sufficient for strength and endure the outside air condition.

A screen 6 is stretched inside the box-shaped carrier 1 along a side wall made of the transparent material 5, and the screen 6 is stretched over a wider area than the transparent material 5. The screen 6 inside can be seen through the transparent material 5 from the outside. The screen 6 is formed of a material that allows the projected image to be reflected on the rear surface and allows the image to be viewed from the rear surface.

Further, a reflecting mirror 7 is provided on the opposite side surface of the screen 6, and the reflecting mirror 7 reflects the image light beam of the projector 8 and projects it on the screen 6.
The reflecting mirror 7 and the projector 8 are arranged. Therefore, the inverted image is projected on the inner side surface 6A of the box-shaped carrier 1 of the screen 6 directly projected, but the image of the outer side surface 6B which is transmitted through the transparent material 5 from the outside of the box-shaped carrier 1 is viewed. It will appear as a normal image.

[0011]

As described above, since the present invention utilizes the box-type carrier of the self-propelled vehicle, it can be moved freely, and has the effect of projecting while stopping or moving at any place.

Further, since the screen is viewed through the side wall formed of the transparent material of the box-type carrier, the screen can be made as large as the side wall of the box-type carrier, and the image light beam of the projector can be obtained. Is reflected by a reflecting mirror and projected on a screen, so that an image can be enlarged at a projection distance longer than the width of the box-type carrier.

[0013] Then, a normal image on the back side of the screen, on which the reflected and inverted image is taken, can be seen from the outside of the box-type carrier through the see-through material.
