Abstract

PURPOSE:To easily and automatically perfect the graphic display complying with desired graphic data to be inputted by using plural pieces of picture elements and selectively inserting the respective picture elements into the respective display spaces forming two-dimensional display surfaces on the display belt of a plane panel unit. CONSTITUTION:Plural pieces of the picture elements to constitute one picture element applied with arbitrary colors are used and the respective picture elements are respectively kept stored by color coding with each of the colors into respective color coding storage parts 40 of a picture element color coding storage unit. The respective picture elements selected and delivered from the respective color coding storage parts are selectively inserted by a picture element inserting unit 60 into the respective display spaces on the display belt forming the plane panel unit 20 based on the graphic data to be inputted. Since the electric power necessary for the operations is only the electric power for driving a driving power part, the lower electric power consumption is necessitated and besides, there is no need at all for taking the problems, such as generation of noises and heat, into consideration. In addition, there is no limitation on display colors in principle.

5. A color display module is controlled by the host computer 11 via the input/output crab unit 17 and displays input symbol data in color.

Here, in this case, a real color display! The input of the design to be output and displayed is done as follows. That is, by inputting desired symbol data from the input device 12 while checking using the CRT monitor 13, the input symbol data is transferred to the host computer 1.
1 to the input/output crab unit 17 of the color display module 16, and symbol data previously stored in the external storage device 14 is called from the external storage device 14 and sent to the input/output crab unit 17 by the host computer 11 in the same manner. sent to.

Further, in the color display module 16, a plurality of pixel elements a for each color are used for color display, and each of these pixel elements a is selectively selected based on the pattern data, as described later. In this case, each pixel element a has a size that is easily removable and suitable for forming individual pixels. It is formed into a single body such as a solid or hollow shape having a spherical shape or a short cylindrical shape with a length equal to the outer diameter, and a predetermined color is applied to each of the single bodies.

Further, reference numerals 20, 30, 40 and 60 are a flat panel unit, a pixel discharge unit, and a storage unit for each pixel color, which constitute the color display module 16.

and a pixel loading unit, the flat panel unit 20 forms a required pattern display by combining and juxtaposing the individually selected pixel elements a for each color, and the pixel discharging unit 30 , each pixel element a is discharged from the flat panel unit 20, and the pixel color storage unit 40 separates each pixel element a sent from the pixel element discharge unit 30 by color. Once stored, the pixel loading unit 60 converts the pixel a for each color stored in the pixel color storage unit 40 into display pattern data input from the input 8 crab unit 17. Based on this, each pixel element a is selectively loaded into the flat panel unit 20, and each pixel element a is circulated between these units as required for each symbol display.

It is possible to sequentially move upward as indicated by arrows at each set pitch interval p, and the movement is started by inputting new display symbol data to the input device 12, as will be described later. , In the process of the movement operation, the plurality of pixel elements a of each color that have already been displayed are sequentially discharged from each display space 24, and each of the empty display spaces 24 Based on this newly inputted pattern data, a plurality of pixel elements a for each color are sequentially and selectively combined and inserted into the display to display the pattern again. In other words, as new symbol data is input, the symbols displayed in the display window 19 disappear one after another from the upper side, and in their place new symbols appear from the lower side. You will be killed.

Next, the pixel ejection unit 30 is provided at the upper part of the back side of the flat panel unit 20, and is ejected from each display space 24 as the display belt 21 moves to display a new pattern. A collection chute 31 for receiving each pixel element a. and a collecting gutter 32 provided at one end thereof, and each pixel element a received in the collecting chute 31 is connected to the collecting chute).
31 and are assembled on the collecting gutter 32, and in this way, each pixel a that had previously formed the required pattern display is removed from each display space 24 of the flat panel unit 20. Since all of them are discharged, each display space 24 on the back side of the flat panel unit 20 becomes empty.

Next, the pixel color-specific storage unit 40 temporarily reserves the individual pixel elements a passing through the collection gutter 32, and a color discriminator 41 with an intermittent discharge control mechanism 42 for discriminating the color thereof.

and a feed reservation control mechanism 50 provided in the intermediate portion thereof.
A delivery gutter 49 is provided.

Therefore, the pixel color storage unit 4 configured in this way
In the case of 0, the pixel a discriminated by the color discriminator 41
The color passes through the feed chute 43 and is guided to the feed cover plate 45 that is selectively raised in response to a color discrimination signal, and is stored in each storage section 44 for each color, sorted by color. . Then, as described above, the pixel a of a specific color is selected by the display selection signal based on the symbol data,
By opening the feed-out bottom plate 47 of the feed-out portion 46 in the corresponding storage portion 44, from the feed-out portion 46,
Only one pixel a of the selected color is sent out, and is guided to the sending chute 48 to reach the sending gutter 49, and the feeding reservation control mechanism 50 of the sending gutter 49 is activated.
It will be temporarily reserved.

Further, the pixel loading unit 60 is mounted on the back side of the flat panel unit 20 when the display belt 21 is moved and each pixel element a is discharged from each display space 24 as described above. Of each display space 24 in the state, a guide rail 61 is provided in parallel to each row of display spaces 24 in the left and right direction corresponding to the loading position set at the lower part of the back surface side. and is guided by the guide rail 61, and the delivery gutter 49
