Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to an electronic bulletin board device used for displaying various types of guidance, advertisements, etc. and for general decoration.

(Prior Art) In a conventional electronic bulletin board device, it is not possible to increase or decrease the number of light sources in order to make the entire screen bright and uniform according to the size of the screen and the distance between the screen and the light sources. Of course, it can be configured by ensuring a certain space between the screen and the light source, or by interposing a mark sheet-shaped translucency adjusting film between the light source and the screen, and from the periphery of the translucent plate after the screen. It is designed to compensate for light, use reflectors with various cross-sectional shapes, and adjust the mounting pitch of the reflectors so that the screen is not bright or dark.

(Problems to be Solved by the Invention) However, the above-described conventional electronic bulletin board device has the following problems.

If a certain distance is secured between the light source and the screen, the entire screen tends to be dark, and even if trying to solve this insufficient light quantity by making the light source brighter, the screen part close to the light source is concentrated. The bright and dark phenomenon of light in the bright and dark surroundings cannot be avoided and cannot be thinned. Even if a mark sheet-like light-transmitting adjustment film is used, since the brightest part of the film is shielded to adjust the overall brightness, the entire amount of light is insufficient and cannot be thinned.
Also, the one that supplements the light from the periphery of the translucent plate after the screen is not enough to eliminate the light and dark only by the outer periphery becoming bright, and above all, the translucent plate becomes thick and hinders the thinning. Of course, due to the extreme increase in weight, it was necessary to strengthen the frame structure and further strengthen the installation means, and there was a problem that the installation itself was impossible depending on the installation conditions.

On the other hand, in the case of using a reflector, as long as the function of the reflector is sufficiently exhibited, the problems of insufficient light amount and light-dark phenomenon of the entire screen are solved, and thinning is possible, This type of device still has unsolved problems regarding the size of the screen and the freedom of the distance between the light source and the screen, that is, the thickness of the device, and the relationship between the power supply capacity and the number of light sources. .

Specifically, this type of device has various sizes and thicknesses, and various sizes and thicknesses and the number of light sources are required depending on the application such as the installation place. For each device, it is necessary to individually form and prepare each reflection plate so as to exert a suitable reflection effect, and as a result, the size and thickness tend to be limited, and the cost is also high. It was

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an electronic bulletin board device having no limitation in size and thickness and having a bright and uniform entire screen.

(Means for Solving the Problems) In the electronic bulletin board device of the present invention, the holding portion on the edge side of the frame body surrounds the outer periphery of the display body in a surrounding shape, and the locking collar is provided inside the frame light source. And mount them facing each other so that each locking collar is provided with an appropriate number of flanges in parallel in the depth direction, and a reflection plate is provided between the appropriate flanges of the facing locking collars through the rear side of the light source. It was constructed in a curved shape.

Further, in the present invention, the locking flange may be formed separately from the frame body, integrated with the frame body or both, and may be appropriately selected according to the number of the reflection plates.

The equipment of the backboard is optional. This back plate may be in the form of a single plate or a plurality of divided plates, or may be in the form of a rod. In the case of a divided structure of a plurality of plates, it has a structure integrally formed with a dedicated joint member or a locking collar. It is assembled by a joint member. It is also possible to provide the back plate with a supporting member for the light source, an attachment such as a locking collar, a transformer, etc., and to mount the light source and the reflecting plate into a unit to mount it on the frame.
