Discontinuous or continuous characters, pictures, and patterns are formed on respective display plates 2 and the light sources are turned on and off in order. Consequently, any wide space is secured on the front surface side of the display plates 2 and the device is made thin, and reduced in size, weight, and cost.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device in which several different types of display can be switched by irradiating a light source with one display device.

[Prior Art] This type of display device conventionally has a transparent substrate such as glass or a resin plate provided with a colored layer of letters, pictures, or patterns in the form of a mesh or dots to improve transparency, as shown in FIG. 3, for example. The display boards b1c are arranged in parallel in the front and back inside the housing a, and an illuminated signboard d is provided at the back of the display board b1c, and light source lamps e1f are provided at the top and bottom of the front side of the display board bsc. are arranged respectively, and a large number of lamps g are arranged in parallel on the back side of the illuminated signboard d.

When only the light source lamp e is turned on, the picture on the display board is displayed and can be seen through the smoked board on the front.Similarly, when only the light source lamp f is turned on, the picture on the display board is displayed. If the board C can be displayed and only the lamp g is turned on, the illuminated signboard d can be displayed. Furthermore, if none of the light sources is turned on, the display will be in a dark box state with no display at all.

[Problems to be Solved by the Invention] According to the conventional display device as described above, the light sources of the display boards are arranged at the upper and lower parts of the front side, so the space on the front side of each display board is saved. Since it must be held relatively large, the overall depth of the display device becomes large, making it large and heavy, and also increasing cost.

The present invention was made to solve these conventional problems, and a technical object thereof is to provide a thin, small, lightweight, and low-cost display device.

[Means for Solving the Problem] As a means for solving this technical problem, the present invention provides a display device in which a plurality of display boards that can display a pattern when irradiated with a light source are arranged in parallel, in which the light source is connected to the display. The gist is a configuration arranged on the end face of the plate.

[Function] Since the light source is disposed on the end face of the display board, there is no need to take up a large space on the front side of the display board as in the conventional case, which significantly reduces the depth of the display device and makes it thinner. This makes it possible to reduce the size, weight, and cost. In addition, by applying discontinuous or continuous characters, pictures, or patterns to each of the display plates and turning on and off the light sources in sequence, a changing picture or moving picture display can be created.

[Examples] The present invention will be explained in more detail below with reference to illustrated examples.

In the figure, 1 is a housing of the device, inside which a plurality of display boards 2 are arranged side by side in the front and back direction, and an illuminated signboard 3 is further provided at the back of the housing. The display board 2 has different patterns 2a on its back side, and light source lamps 4 are arranged close to each other on the upper and lower end surfaces. The illuminated signboard 3 has a pattern 3a made of transparent ink on the front side of a transparent substrate, a large number of lamps 5 arranged side by side on the back side, and a reflective plate 6 attached thereto. A smoke plate 7 is fitted into the front opening 1a of the housing 1.

The display device according to the present invention is configured as described above, and when the light source lamp 4 of any one of the four display plates 2 is turned on, the light rays from the light source lamp are irradiated all over the display plate. A picture can be displayed, and the picture can be seen from the front of the housing 1 through the smoke plate 7. Moreover, when only the lamp 5 is turned on, the pattern 3a of the illuminated signboard 3
can be visually recognized. Note that a reflective layer 2b (vapor deposited layer or bright color layer) may be provided on the back surface of the pattern 2a, if necessary.

In the case of the present invention, since the light sources of each display plate are arranged close to the bottom end faces of each display plate, the distance between the display plates can be minimized, and therefore a thin display device can be formed. This is particularly advantageous when there are a large number of display panels.

In addition to displaying each of the display boards 2 or the illuminated signboards 3 separately, it is possible to combine several display boards 2 to display a composite picture, or to combine only the display boards, but also to display the display board and the illuminated signboard. A combination with 3 is also possible.

In some cases, only the display board 2 and the electrode signboard 3
It is also possible to use a display device without.

Furthermore, as a light source for the display board 2, an optical fiber (not shown) may be used in addition to the lamp.

In the embodiment shown in FIG. 1, the pattern 2a is formed using normal printing ink, but if ultraviolet emitting ink is used instead, it will be almost white when normal light is irradiated from the outside. Therefore, when ultraviolet rays are irradiated, only the pattern 2a portion emits light, making the pattern pattern visible. Therefore, when the rear pattern illumination is turned off, the pattern 2a does not remain as an afterimage, which is convenient.

In this case, the light source lamp 4 will be an ultraviolet lamp.

FIG. 2 shows another embodiment of the present invention, and the basic configuration is similar to the conventional example shown in FIG. 3, but the difference is that the pattern formed on the display plate 12 is colored by ultraviolet light. It is composed of a pattern 12a formed of ink and a bright color ink layer 12b provided below the pattern 12a, and furthermore, an ultraviolet lamp is used as the light source lamp 14. The other configurations are completely the same as the conventional one.

In the case of this embodiment as well, when normal light is irradiated from the outside, the color is almost white, and when UV rays are irradiated, only the pattern 12a portion emits light, making the pattern pattern visible. Therefore, when the rear pattern illumination is turned off, the pattern 12a does not remain as an afterimage.

[Effects of the Invention] As explained above, according to the present invention, in a display device having a display plate in which a net-like or dot-like colored layer is provided on a transparent substrate, a light source is disposed on the end surface of the display plate. , it is no longer necessary to take up a large space on the front side of the display board as in the past, the depth dimension of the entire device is reduced and it can be formed thinner, and it is also possible to reduce the size and weight, resulting in material savings. Excellent effects such as cost reduction can be obtained. Furthermore, a variable moving image display can be created by continuously turning on and off the light source.

Furthermore, since it enables a thin display, it can be used as part of the display section of various machines, automatic teller machines, automatic ticket vending machines, etc., and can be widely used as a compact and portable hand-held display. You can also do it.

In addition, if the colored layer of the display pattern is formed with ultraviolet emitting ink, it will be almost white when normal light is irradiated from the outside, and when ultraviolet rays are irradiated, only the pattern 2a will emit light, and the pattern will be can be visually recognized. Therefore, when the rear pattern illumination is turned off, the pattern 2a does not remain as an afterimage, which is convenient.
