Description

A device for displaying multiple images in sequence}

The present invention relates to a multi-image display device, and more particularly, to a multi-image display device that can be displayed repeatedly in sequence a plurality of images for use 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.

Therefore, the present invention is to solve the above problems, it is possible to display four images by one image board so that viewers do not feel bored and can improve the advertising efficiency, the screen is switched The purpose of the present invention is to provide a multi-image display device having a high speed, which can greatly improve the effect of advertisement, and have a relatively simple structure and low production cost.

The image board 76 installed corresponding to the central hole 64 is composed of a plurality of image cells 74, and these image cells constitute respective images constituting the multi-screen for displaying the multi-screen. The cells 74 are arranged alternately with each other.

That is, in the case of two screens, the sets of the cells 74 constituting each screen are alternately arranged in the left and right or up and down directions. In the case of the four screens, the sets of the cells 74 are each. Since it is arranged alternately in the up, down, left, and right directions, as the mask 86, in which the through-holes are continuously formed at the predetermined interval, moves up, down, left, and right, only the combination of the cells 7 of the corresponding screen is projected. Will be displayed on the

In this case, the image board 76 in which the cells 74 constituting the image are formed is preferably made of a transparent synthetic resin material such as acrylic material having a predetermined rigidity, and directly prints an image on the image board 76 or It can produce by the method of attaching an image film.

In addition, the image board 76 is installed to be fixedly attached to the upper end of the image frame 70 by a predetermined fixing means such as a bolt, so as to operate integrally with the image frame 70.

The image frame 70 is formed through the first guide means 72 to form a long hole in the horizontal direction on the left and right upper and lower sides, respectively, if the image frame 70 is in close contact with the front of the fixed frame 60 The fixing pins 62 are inserted into the first guide means 72 to allow the image frame 70 to reciprocate in the horizontal and horizontal directions with respect to the fixing frame 60.

In addition, the image frame 70 is the drive means 90 is fixedly installed by the bolt 106 while the drive means 90 or the fixed pin 62 is fixed to the mask frame 80 without interference Various through grooves 78 and 79 are formed to be installed, respectively.

The mask frame 80 which is continuously installed on the front of the image frame 70 has a mask 86 corresponding to the image board 76 is fixedly installed on the upper portion, a plurality of oval formed long in the longitudinal direction at the edge Two second guide means (82) are formed therethrough, and the lower driving means (90) inserted through the through grooves (78) of the image frame (70) is fixed to the fixing means such as bolts (108). .

At this time, the second guide means 82 is inserted into the fixing pin 62 of the fixing frame 60, the mask frame 80 is able to reciprocate sliding up and down with respect to the fixing frame 60. It is.

On the other hand, the driving means 90 to reciprocally slide the image frame 70 and the mask frame 80 up and down or left and right, respectively, the cam fixed to the end of the rotating shaft 98 of the motor 96 ( It consists of a rotational displacement means 92 consisting of 100 and the bracket 94 is periodically reciprocated by the rotational displacement means 92 in the up, down, left and right.

In this case, the rotation displacement means 92 is connected to the mask frame 80 through a fixing bracket 102 fixedly attached to the mask frame 80 with a bolt 108 through the through groove 78 of the image frame. It is fixedly installed, and the bracket 94 is fixedly fastened by the bolt 106 at the lower center of the image frame 70.

Here, the cam 100 is composed of r1 and r2 (r1 <r2), each of which is partially different in diameter as shown in FIG. 4, so that the rotational movement is changed into a linear reciprocating motion according to the rotational angle of the cam 100. In the bracket 94 inserted into the outer portion of the cam 100, the bracket 94 reciprocates up, down, left, and right, respectively, as the cam 100 rotates.

In this case, the relative motion of the image frame 70 and the mask frame 80 as the bracket 94 moves with the rotation of the cam 100 will be described with reference to FIG. 5.

FIG. 5A shows an initial state in which a large diameter part faces downward, and the fixing pins 62 are in contact with the right end of the first guide means 72 of the image frame, respectively, and the second guide of the mask frame. The first screen is projected outside while being in contact with the lower end of the means 82.

Subsequently, in FIG. 5B, in which the cam 100 is rotated 90 degrees in the clockwise direction, a portion having a smaller diameter of the cam 100 rotates to the left and the coupled bracket 94 moves relatively to the right. In addition, the image frame 70 integrally coupled to the bracket 94 is also horizontally moved to the right along the fixing pin 62 accommodated in the first guide means 72, so that the fixing pin 62 It is in contact with the left end of the first guide means (72).

At this time, since the mask frame 80 has not moved, the second guide means 82 and the fixing pin 70 maintain their original state, thereby projecting the second screen to the outside.

And when the cam 100 is rotated by 90 degrees clockwise again, as shown in Figure 5c the small diameter of the cam 100 is rotated to the upper side and the coupled bracket 94 is vertically lower direction The cam 100 itself moves to the lower side while receiving the force, and the second guide means 82 is lowered along the fixing pin 62 in the mask frame 80 integrally coupled to the cam 100.

When the cam 100 is rotated by 90 degrees clockwise again, as shown in FIG. 5D, the smaller portion of the cam 100 rotates to the right and the coupled bracket 94 moves to the left. The first guide means 72 is horizontally moved to the left along the fixing pin 62 in the image frame 70 integrally coupled to the bracket 94 and the cam 100, and thus the fixing pin 62 is in contact with the right side of the first guide means 72.

At this time, since the mask frame 80 is not moved, the second guide means 82 and the fixing pin 70 maintain the previous state, thereby projecting the fourth screen to the outside.

As described above, the image frame 70 and the mask frame 80 alternately reciprocate alternately with each other to continuously view four different screens.

In this case, the first guide rails 72 and the second guide rails 82 form long holes in the horizontal direction and the vertical direction, respectively, but the first and second guide rails 72, 82 are respectively It may be configured in a horizontal direction.

In addition, in the above-described configuration, the cam 100 and the bracket 94 are configured to be fixed to the mask frame 80 and the image frame 70, respectively. In addition, the cam 100 and the bracket 94 are the image frames, respectively. Even if it is fixed to the 70 and the mask frame 80, the same effect can be obtained.

According to the present invention having the above-described configuration, since the driving means for driving the image frame and the mask frame can be made only by the combination of the cam and the bracket, the configuration of the driving means is simple and its size can be made compact. In addition to the small area, there is an advantage that the image can be replaced simply by replacing the image board coupled to the image frame.

Therefore, the multi-screen display device of the present invention by such a simple configuration is suitable for use as a small propaganda billboard installed in the room or a billboard installed in the front of the vending machine.
