Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color duplex color type II JIEI device.

Conventionally, electrostatic color duplication i**h, - every time the document is exposed,
-Color of color- Since the image form IIt is performed, a large number of color images are to be photographed, and the number of copies required for the same original document is required to be reproduced several times. In addition, electrostatic color copying equipment uses a color filter T-sheet and requires a strong light S for exposing the original, compared to a normal electrostatic monochrome duplication device.

Therefore, when a plurality of sheets of paper are required, adverse effects such as fading and yellowing of the originals occur due to the continuous printing of the originals. Furthermore, since the powerful light source is a heat source, the temperature inside the aircraft rises, so countermeasures are needed.

Moreover, the energy of the light source Oh is also used in large quantities for a long time, which is uneconomical. Furthermore, since the scanning section and the image forming section must always operate in synchronization, there is also the drawback that the control of the entire apparatus becomes complicated.

The present invention is intended to eliminate the above-mentioned drawbacks, and includes a memory storing my data, a plurality of color processing means for forming a color image on a recording material, and a method for forming a repeat color image using the image data. and means for successively returning image data and controlling the selection sequence of the color processing means according to the read data, and the father's memory stores a good number of image data according to the number of colors that can be formed. The above memory is capable of storing multiple color data for a single exposure of the original, and the control means allows the line specific image data to be stored. A specific color processing means is made to correspond to each specific color], and the original is read for each specific color, converted into a standard electric signal-e, and sequentially stored in the memory.

Forward. - Image memory device! At least the sent color sin data is stored in 61Pj & 4111C of the original color 11. Color - Association formation [1113 is -
The color data stored in the image storage device 2 is image-formed on a paper storage medium to obtain a color image. The tube layer control device 4 performs each @tl to 30 controls/tubes (2).

Hereinafter, a detailed explanation of superposition will be given based on further examples.

Fig. 2 is an example of a color original reading device 1 using an image sensor 0eDIC. The original 10 has a color filter 18
, lens ll', 11 images are read by the CCD 12 by line self-scanning, and converted into serial electrical signals. Five eight color filters are red, green, and more! It has a colorless (ND) tJ color filter, and the filters for each color are sequentially switched 9 to separate JllllIlO into three colors, which are read by the COD, and electrical signals for each color component are output. Each filter except ND has a lli-shaped bottom formation,
In order to form a color image of each color by using a cyan developer, a magenta developer skin, and a yellow VL soda, these are necessary to obtain a good bias ratio of each color component. When forming a black and white image using an ND colorless filter, a black developer is used to obtain a black and white image in one transfer. This makes it possible to shorten the process time for forming an image with only one black color.

C0D12% The thread 9 containing the lens 111 and the color filter 18 moves the document 10 in the direction of the arrow in FIG. The above series of filter replacement, optical system movement, and optical system drive path 16 are performed. First, set the red filter, then set the red component on the green/filter by reciprocating scanning of the 1alfi optical system, then set the green filter on the second scanning section, then set the blue filter, and then set the blue filter on the third scanning section. Take blue color I11 when scanning. CCDIIK at the first waterfall basin
The read color image data of 9 red components is converted from analog to digital by a k0 converter, and then encoded by the same Mt via a Δ rough ame card 14 and an image data transmission circuit. The image is sent to the image storage device 2 shown in the figure and stored in the appetizer IK. Thereafter, the read data of the second and third colors are sequentially sent to the storage device 2 in the same manner and stored in the memories 2 and 3 in sequence. ls.

The iI is fully determined and the image data transmitted from the Il+ is enabled (21°) Next, the color identification data sent to the peak of the received data is determined, and the image data decomposed by the red filter is used. When it recognizes that there is something (3), it stores the data to be sent to memory 1 (41. When the storage for 1 scanning is completed and the next data is from the green filter, it is stored in memory 2. Store (5
). Similarly, other data t is stored in the memory 3.4 (6.7). When all data reception is completed, the fifth
A termination signal is output to the management control unit shown in the figure via the interface (8).

Next, when a full-color l-lint copy command g1 is input from the management, it does not judge it and outputs the data of the #p component from the memory l.
When the output power is reached, the data is output from 2°3 (11, 12), $1!41! The image is transmitted to the image forming tack setting section i1, and an image is formed in the same color as the original. In the case of a two-color lint command, it sequentially accesses the red/marginal and Ia % 172 and 3 and outputs the red/marginal oor-ta. 1 koshiki 1.1

Referring to FIG. 7, the control of the management control device 40 will be explained. This flow is stored in the program expansion ROM 6g. tz key & -y 67 or 6o It is determined whether the scan start command is input. tgi is 0, while error diagnosis of each device 1 to 3 is performed 111°. For example, an abnormal interface output of device 2 is checked and checked. As soon as the scan start input is received, a signal is output to start the reading operation by alk1.2KCOD and to start storing my data in the memory (3
). When it is detected by the signal from the t-key 112 that the storage of the mail is completed (4), the key determines that the print color mode V is input from the -r.

In the case of the two-color red/green color mode, q outputs command signals related to printing 2 and 3, and outputs command signals for setting the developing units 107 and 108. When completed, a complete signal is output to I![2゜3 to stop each machine.
According to the above operation, for 1 liter, an electrostatic color copying machine would have to expose the original document 9 times (number of copies x 3) times, but only 3 exposures will be enough. Furthermore, if a single horizontal color solid-state sensor is used for color reading or equipment,
Since it is possible to electrically read three colors at once, only one exposure is required. Since the exposure time is shortened, the original color fades, yellowing occurs, and II decreases when the temperature inside the machine increases.

In addition, a screen-like photoreceptor with memory properties is used, and its V
By forming latent image tubes corresponding to the three color separations on the ram circumference, similar repeated copying becomes possible.

In this example, any color data can be stored in the memories 1 to 4 of the storage device 12, and any color data can be stored in the memories 1 to 4 of the storage device 12. It is also possible to make it correspond to the memory of the meeting, and the key of the management device 14? - You can't make that choice.

Furthermore, semiconductor memory can be used for image storage, making it easier to create documents.
It can be used as a color printer for a word processor (word processor) or a computer for office work.

That is, a character generator is used on the side of a word processor or a computer for office processing to generate image data, and the image data receiving circuit 20 of the image storage device 2 generates image data.
It can be coupled by inputting
