Description

A device for displaying multiple sterographic images in sequence}

The present invention relates to a multi-stereoscopic image display apparatus, and more particularly, to a multi-stereoscopic image display apparatus which allows two different stereoscopic images to be sequentially and repeatedly displayed in order to be used mainly as a billboard.

In general, propaganda towers or billboards display images and texts that the public wants to inform the public, and various image display devices have emerged due to the development of display device technology and computer technology.

In particular, a video display device that can implement various videos and texts using a computer has an advantage that a random image can be realized as a video lively, but manufacturing cost is very high and it is inefficient to deliver a simple image.

Therefore, in the past, various forms of advertisement boards for displaying a plurality of still images were used in practice. As a representative example, a plurality of advertisements are intermittently rotated by a translucent advertisement film printed with a predetermined picture or character. There was a form that allowed the content to be displayed.

However, this type of display device is relatively inexpensive but the thickness of the rotating roll to rotate the film is inevitably thickened, and the film is rotated at a moderate speed, and thus the screen is changed. There was a problem such as noise is generated.

In addition, the conventional multi-screen display device is composed of the configuration as shown in Figure 1, a multi-image film 12 is printed on the support frame 14, the printed image or characters that can represent a plurality of images In this case, one image can be expressed at a time through the mask 16 having the through hole 15 through which only one quarter of the film can pass, and the mask 16 is sequentially moved in a planar manner. Branch images can be expressed.

At this time, the driving means 22 for precisely sequentially moving the support frame 14 supporting the multi-image film is provided with cams 24 at left and right sides at the lower end of the support frame 14. And up and down by the drive belt 26 driven by the drive pulley 28 to operate these cams 24 in synchronism with each other, while the sliding support interval 30 protruding from the lower end of the support frame is returned. It is made to move to the left-right direction by the spring (not shown).

However, such a conventional multi-image display device is that the image is switched according to the displacement that precisely moves the mask film on which the through-hole is formed, so the first accurate position adjustment must be preceded before the start of operation.

In addition, not only two or more cams are required on the left and right sides in order to drive the support frame correctly, but also driven by a return spring or a driving belt, so that excessive force or long-term use may cause the screen to be loosened due to spring loosening or sagging of the driving belt. There was a problem that the screen is deteriorated because it cannot be moved.

In addition, the patent application 99-33547 "multi-image display device" filed by the applicant on August 14, 99, the light source 50 and as shown in FIG. A plurality of fixing pins 62 protruding from the front surface, and a fixing frame 60 having a central hole 64 formed at a central portion thereof so that the light source 50 is transmitted within a predetermined range; A plurality of first guiding means 72 inserted into a part of the fixing pin 62 can slid in a straight direction the transparent image board 76 which displays the combination of the sequential image cells 74 alternately. To support the image frame 70; A plurality of see-through holes 84 to selectively see only a combination of some of the image cells 74 of the image board 76 in the plurality of second guide means 82 inserted into the remaining part of the fixing pin 62 A mask frame (80) for slidably supporting the formed mask (86) in a direction perpendicular to the first guide means (72); The image frame 70 and the mask frame 80 is composed of a driving means 90 for periodically performing a relative cross reciprocating movement up, down, left and right.

However, since the multi-image display device made of the mask and the film as described above only projects up to 1/4 of the light projected from the light source, it is possible to visualize the image only indoors due to low illumination and low illumination when installed outdoors. There was a decisive issue that could not be noticed by passers-by.

In addition, the multi-image display device consisting of a combination of these masks and a film projects only one quarter of the film by alternating the four positions of the mask, so that the distance between adjacent cells is not too wide and operates up and down, thereby allowing the left and right visual differences to differ. There was a drawback that it was not possible to display the stereoscopic screen used.

Accordingly, the present invention is to solve the above problems, by repeatedly displaying two stereoscopic images using one image board so that people do not feel bored and improve the advertising efficiency, the screen is Its purpose is to provide a multi-stereoscopic image display device that has a high conversion speed and a vivid feeling of three-dimensional effect, which can greatly improve the advertising effect, but also has a relatively simple structure and low production cost.
