Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a display device such as a guide board or an advertising board, and particularly to a display device that can selectively change the screen information that is the display content. be.

(Prior Art) Conventionally, this kind of display device that can change the display content has a type in which the display itself is turned over as a means to change the display content, or a display device that lights up using an electric or electronic mechanism. There are known devices that change the position.

(Problems to be Solved by the Present Invention) However, in these conventional displays, where the display content is changed by flipping the display itself, the task of flipping it over is troublesome, and the display does not hold properly. They had drawbacks such as not being fixed in place, and those using electric or electronic mechanisms did not require turning over, but had drawbacks such as complicated structures and high costs.

In view of this, it is an object of the present invention to solve these drawbacks of the prior art and provide a display device that allows easy operation to change display content, has a simple structure, is inexpensive, and has clear display content. It is something.

(Means for Solving the Problem) In order to solve this problem, the present invention includes a mask plate 1 in which light-shielding parts are regularly arranged on a transparent plate, and a plurality of displays that pass through the transparent parts of the mask plate 1. The positional relationship between the mask board 1 and the information board 2 is changed. and a positional relationship changing mechanism for selecting screen information, and the light shielding part 1a, the background color part 2a, and each color point group 2b,
We attempted to solve this problem by clarifying the relationship between color and visibility between 2c and...

(Function) The present invention not only simplifies the structure of the display and simplifies the operation to change the display contents, but also improves the light shielding part 1a, the background color part 2a, and each color point. Visibility could also be improved by selecting color combinations of groups 2b, 2c, . . . .

(Example) Hereinafter, an example of the present invention will be described based on the drawings. 1st
The figure is a perspective view of a display device according to an embodiment of the present invention, and l is a mask plate, as shown in FIG. The portions 1a are regularly arranged by printing or the like. Note that this light shielding part 1a is not only formed by a group of square points with a small area as in this embodiment, but also by forming circular holes regularly arranged only in the part corresponding to the transparent part, for example. Alternatively, the remaining portion may be formed as a light shielding portion. Reference numeral 2 denotes an information board on which a plurality of pieces of screen information, which are display contents, are formed by printing or the like, and when the screen information to be displayed is, for example, two types, as shown in FIG. Color point group 2b ("
Two types of screen information that can be selected are expressed by 2C (forming the character "J") or 2C (forming the character "J").In addition, one of the surfaces in contact with these mask board 1 and information board 2 Alternatively, the positional relationship changing mechanism can be operated more smoothly by applying a frictional resistance reducing material to both, interposing a small-diameter sphere, or forming a small projection with a rounded tip.3 is the mask plate l and An outer frame for supporting the information board 2, 4 a cam rotatably supported by the outer frame 3 for moving the mask board, 5 a handle for operating the cam 4,
The cam 4 for moving the mask plate and the handle 5 constitute a positional relationship changing mechanism that changes the positional relationship between the mask plate 1 and the information plate 2 to select screen information, and by rotating the handle 5, Display contents can be selected by moving the mask board 2 up and down.

FIG. 2 shows another embodiment of a mechanism for changing the positional relationship between the mask plate 1 and the information plate 2, in which the mask plate 1 is moved up and down using the slope 7 of the pushing tool 6.

In the above embodiment, the direction of movement of the mask board 1 is shown as being vertical, but it may be changed to the horizontal direction, or the information board 2 may be moved instead of the movement of the mask board 1. It may be configured as follows.

In addition, an appropriate number of positional relationship changing mechanisms such as the cam 4 and the pusher 6 may be installed as needed, and the mask plate 1 may be actively moved using springs, magnets, etc.
In that case, a stopper for the limit of movement can be provided if necessary. Furthermore, if a fixing device such as adhesive tape is installed on the back side of the information board 2 or the outer frame 3, the display device can be installed more easily.

5 and 6 show the display results of this example, and FIG. 5 shows the state shown in FIG. 1, that is, the mask plate 1
6 shows the display content "In preparation" when is in the lowered position, and FIG. 6 shows the display content "Open for business" when the cam 4 is rotated from the state shown in FIG. ” is shown.

Next, the light shielding part 1a of the mask plate 1, the ground color part 2 of the information board 2
The color relationship between color point a and the color point groups 2b, 2c, . . . will be explained in detail. First, regarding the color of the surface of the light-shielding part 1a of the mask plate 1, it is preferable to use a white color with a high reflectance because the visibility of the screen information on the information board 2 will be hindered by the reflected light. do not have.

Therefore, it is preferable that this light shielding part 1a be of a black color having a low reflectance. Next, regarding the color relationship between the ground color portion 2a and the color point groups 2b, 2c, .

B. When a white color is used as the ground color portion 2a, and a black color is used as the color point group 2b, 2c, .

A case where a black color is used as the mouth and ground color portion 2a, and a white color is used as the color points 1i2b, 2c, .

C. When an achromatic color is used as the ground color portion 2a, and a chromatic color is used as the color point group 2b, 2c, . In this case, the results were particularly clear when red or blue was used as the chromatic color.

In addition, color point groups 2b, 2 forming each information group
By changing the color for each color point group 2b and 2c, it is possible to change the display effect given to the viewer, and this change is particularly clear when blue is selected for one of the color point groups 2b and 2c, and blue is selected for the other. At the same time, visibility was also good.

(Effects of the Invention) The present invention can obtain the following effects with the above configuration.

1. The effect display device of the invention according to claim (1) is composed of a mask board, an information board, and a mechanism for changing the positional relationship thereof, and the mask board and the information board themselves have a light shielding part or a background color part and a group of color points. Since it is simply formed by printing or the like, it is possible to simplify the configuration, provide a thin and compact display device in the form of a plate, and also simplify the operation of changing the display contents.

In addition, since manual operation is sufficient and no electricity supply is required, not only is there no cost, but there is almost no risk of failure.

2. Effects of the inventions described in claims (2) to (5) In addition to the effects of the above-mentioned 1.

Light-shielding part of the mask board By selecting the color relationship between the background color part of the information board and the color point group, a clear information screen can be obtained and visibility can be improved, so that the original function as a display device is also sufficient. It can be demonstrated. especially,
By changing the color for each color point group 2b, 2c, etc. forming each information group on the information board, it is possible to further change the display effect given to the viewer, and especially to one of the color point groups 2b and 2c. When blue is selected for the other side, the change is clear and an indicator with good visibility can be provided.
