JPS6317477A - Color-changeable monochromatic copying machine with editing function - Google Patents

Abstract

PURPOSE:To easily and simply take a color-charged copy which is edited by a monochromatic copying machine again by reading editing information recorded on copying paper by the reader of an original pressure base. CONSTITUTION:The monochromatic copying machine is provided with an information recording device 13 and the editing information such as mask coordinate information for a color change when a color-changed copy is taken after editing is recorded on the reverse surface of the copying paper. When this copying paper is used as an original to take the color-changed copy, the editing information is read by the reader 18 provided to the original pressure plate 2 to control a copying process. Reediting operation is therefore unnecessary and the color- changed copy is easily and simply taken again.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single color copying machine with an editing function and color changeable, and more particularly, to a single color copying machine having an editing function for masking or trimming a part of a document image. It is.

Conventionally, it has an exposure device that is placed adjacent to the image exposure position of the anti-blood photoreceptor and exposes a designated arbitrary area, and a plurality of developing devices that contain developers of different colors to develop the electrostatic latent image. Monochromatic copying machines with editing functions and color changeability are already known.

With conventional single-color copying machines that have editing functions and can change colors, it is necessary to change the color when recopying a copy obtained by performing wAffi such as masking and trimming. α1 and coordinate input must be repeated again. Therefore, there was a drawback that it was time-consuming.

1. The present invention solves the above-mentioned problems in the conventional single-color copying machine with editing function and color changeability, and provides a copying machine that does not require the same t5 set input operation when copying an edited copy again. The purpose is to provide an opportunity.

(2) Bottom In order to achieve the above object, the present invention provides a recording device for recording an information signal regarding editing on the back side of the copy paper in the middle of the copy paper path from the paper feeder to the paper output tray;
The present invention is characterized in that a reader is incorporated to read information symbols written on the back side of the copy paper on the document mounting table when the original is pressed onto the document mounting table.

The structure and operation of the present invention will be explained in detail based on the embodiment shown in the drawings.

In FIGS. 1 and 2, a document placed on a document table 1, for example, a contact glass, is exposed to light while being pressed onto the document table by a pressure plate 2, and image light is reflected from the document. is read by a reading device and stored as a digital signal.

The writing device is controlled based on the information stored in the reading device, and a predetermined writing image light is projected onto the photoreceptor via the mirror 3.4.

Of course, in such a digital copying machine, it is also possible to directly project the reflected light from the original onto the photoreceptor 5 via the mirror 3.4.

Around the photoreceptor 5, for example, a photoreceptor drum, there are a charger 6, an image exposure position 7, an exposure device 8, a document device 9,
etc. are arranged in order. The document device 9 has, for example, two developing devices a9a and 9b that accommodate document materials of different colors. The number of developing devices is not limited to two.

The exposure device 8 is formed, for example, as an LED array as shown in FIG. 3, and a large number of LED elements constituting the LED array are arbitrarily controlled so that only a predetermined range necessary for trimming or masking is illuminated. .

A developed image formed by the developer on the photoreceptor 5 is transferred to the paper feeder 10.
The copy paper is transferred to a copying machine fed from the printer, and the transferred copy paper is transported to a fixing device 12 by a transport bell (11).

On the back side of the fixed copy paper, the information recording device 13 records information regarding editing, such as coordinate information of the image area to be masked. The recorded copy paper is placed in paper output tray 1.
It is discharged at 4.

As shown in FIG. 4, the information recording device 13 has a platen 15, a thermal head 16 disposed opposite to the platen 15 across the copy paper path, and an ink ribbon 17 for recording by the thermal head 16. The recording device is not limited to a thermal type, but may also be a type such as a stamp.

A reader 18, for example a CCD array, is incorporated in the pressure plate 2 shown in FIG. 1 in order to read information related to editing by the information recording device 13 recorded on the back side of the copy paper. CCD
The array is read in the direction of arrow 19.

When editing during copying, operations are performed using the panel 20 shown in FIG. 5, for example.

For example, if we consider an example in which an image is formed in red only within the frame indicated by the broken line of the document 21 as shown in FIG. is set using the coordinate display key 23. The set image area is displayed on the display unit 24. In the figure (
Xl, Yl) = (123,456), (X2.Y
2) Since the 0 image area indicated by -(789, 123) is designated as red, first press the masking button 25 to instruct masking. When developing with red first or when the colors are reversed, the image is formed first in the image area, so in this case the trimming button 26 is pressed.

During masking, the inside of the designated area is exposed by the exposure device 8 of FIG. 2, and during trimming, the outside of the designated area is exposed by the exposure device, and the inside of the designated area is not exposed. When the masking button 25 is pressed and the black button 27 is pressed, the area is exposed by the exposure device 5 by masking, and the electrostatic latent image within the area is neutralized, resulting in a black image! 59a, the inside of the area is not developed, but the outside of the area is imaged as usual.

After the black image is formed, the image area is next developed with a red developer. At this time, press the trimming button 26 and
By pressing 8, the portion outside the area after image exposure is exposed by the exposure device 8 to remove static electricity due to trimming, and only the area within the image area shown by the broken line 22 is developed red in the developing device 9 using a red developer. When forming images of two or more colors on the copy paper, the paper feeding device 10 can feed the copy paper again for each color, but an intermediate tray is used in the machine to feed the copy paper for each color. It is also possible to adopt a structure in which the image is stored in an intermediate tray after fixing and sent again to the transfer position of the photoreceptor.

By simply specifying the area coordinates, pressing the masking key 25, and pressing the black/red 29, a predetermined edited image as shown in FIG. 6a is copied onto the front side of the copy paper.

In either case, by turning on the display key 31 of the panel 20, the copy paper on which the image has been copied and then being ejected to the post-discharge tray 14 will be printed with the reverse side as shown in FIG. 6 by the information recording device 13. Edit information 33 is recorded in . The editing information 33 mainly consists of coordinate symbols as shown in FIG. 6C. When the display key 31 is turned off, nothing is recorded on the back side of the copy paper.

The copying process involving the above m collections and the recording operation by the information recording device 10 are performed by a control device having a structure as shown in FIG.

Once a two-color copy has been created by editing the original, there may be cases where it is desired to make the same copy again using the copied version as the original. In this case, normally it would be necessary to repeat the above operations, measuring the coordinates and inputting the coordinate signals, but the copy paper after copying obtained above is placed on the document table 1. Since editing information is recorded on the back side of the copy paper, when the pressure plate 2 comes into contact with the copy paper by turning on the recognition key 30 on the panel 20, the reader 18 reads the information and displays the copy paper. Send it to the control circuit shown in Figure 7. At this time, by pressing 29 for red, the above operation is repeated to obtain the same copy. Recognition A30
If you turn it off, you can change the masking area, trimming area, etc. as a new edit.

If you use the first trimmed area as a mask, then trim the masked area and make a black-and-red copy on the copy paper of the image that was first formed with &g shadow collection, you can obtain a copy of the image that is inverted from the copy paper. .

In other words, you can get a reversed copy. Repeat this operation in the fifth
In contrast to the panel shown in the figure, it can be simplified by providing a panel provided with a reversing key 32 as shown in FIG. According to the panel 20 in FIG. 5, when an image has been previously edited and copied and a copy sheet with information recorded on the back is placed on the mounting table 1 as a document and the pressure plate 2 is operated, the black and red keys 29 are pressed. When pressed, the same image as the original is formed according to the information recording, whereas when the reverse key 32 is pressed,
You can obtain a reversed copy with colors reversed from the original.

Since the beginning of the present invention, a copying machine having an edited image can be produced using a simple configuration in which a recording device for recording editing information on the back side of the copy paper is installed in the copying machine, and a reading device for reading the information recorded on the back side of the copy paper is built into the pressure plate. It makes it possible to reproduce the same image using paper as an original in a color-changeable monochrome copying machine,
The trouble of coordinate measurement and coordinate input can be omitted. Since information is recorded on the back side of the copy paper, damage to the image on the back side of the copy paper can be avoided.
