Abstract

PURPOSE:To prevent occurrence of a white streak and blur at junction of images of an edit copy and prevent light fatigue of a photosensitive body by making a main charger and a transfer charger off when the photosensitive body is stopped. CONSTITUTION:When image scanning of a sheet of original is terminated, a photosensitive body belt is stopped, and after setting next original at the reading position, the belt 15 is driven. An exposure scanning means, that is, an automatic original feeding device 2 returns while the belt 15 is stopping. Accordingly, when one copy is taken by editing plural sheets of original, the belt 15 is stopped plural number of times. A main charger 16 is made off while the belt 15 is stopping. A transfer separation charger 23 is made off except when the belt 15 is driven for transfer. Thus, occurrence of a white streak and blur at junction of images in a edit copy, and further, fatigue and deterioration of the photosensitive face of the belt 15 can be prevented.

Description

[Detailed description of the invention]

■Technical field The present invention projects an image of a document onto the surface of a photoreceptor through an optical system without converting it into an electrical signal, forms an electrostatic latent image on the surface, and develops the latent image. In particular, regarding copying devices that project and transfer original images onto sheets such as recording paper,
The present invention relates to an editing copying apparatus for obtaining an edited copy by extracting and/or erasing an image of one or more areas of one or more original documents. ■Prior Art Editing A typical conventional copying machine includes an image reading device that scans an image and obtains an electrical signal (image information) corresponding to the image light;
Page memory and read/write controller

[and memory read information
Equipped with a printer to print out the image information page
When writing to memory, and/or when writing from page memory.
When reading image information, some image information may be partially erased.
Or remove or replace the manuscript of 1 or 2 pages or more.
Obtain a copy with one or more edits made. Copying machines that perform editing using image information processing have high
You can perform detailed and complex editing with relative ease.
. However, the editing of the original image projection/transfer format as described above is difficult.
Copying devices do not convert original images into electrical signals.
The image is projected onto the photoreceptor surface using an optical system, so editing is not done mechanically.
It is necessary to erase one image before or after exposure.
This is done by partially erasing static electricity on the surface of the photoreceptor, and the scanning of the original is
scanning direction (Y direction: corresponds to the direction in which recording paper is fed for transfer.
) image shift depends on the timing of feeding the recording paper to the transfer unit.
Adjustment is performed in the direction perpendicular to the scanning direction of the document (X direction).
The image shift (direction) projects the optical image of the JM draft onto the surface of the photoreceptor.
This is done by adjusting the shift of the optical system in the X direction. However, in the past, exposure scanning and updating of the exposed surface of the photoreceptor
The rotation for printing is synchronized, so multiple originals can be
Sometimes, each sheet of the original is exposed to light. Copies by executing copy cycles such as development, transfer, and fixing.
When copy processing is finished and the original is replaced, copy processing will be performed like this.
Reload the paper that has been processed into the paper feed system.
, and copy the new original in the same way.
It takes many copy cycles to get one edited copy.
The good news is that the recording paper is misaligned when resetting it.
, the problem of misalignment in the edited image or the same
- Paper may be pushed, wrinkled, or wrinkled due to repeated feeding of paper, resulting in
There are problems such as image shift and transfer failure. ■Purpose The first objective of the present invention is to reduce image deviation in edited copies.
Copies required to obtain one edited copy for the purpose of
-0 lines whose secondary purpose is to reduce the number of cycles
The third purpose of the invention is to use relatively simple hardware and components.
Obtain edited copies with less image shift using P-cycle control
That's true. ■Structure In order to achieve the above object, in the present invention, the exposure of the original is
Selectively synchronize and operate the optical scanning system and photoreceptor drive system.
In addition to setting up the mechanical system so that the operations can be separated, the exposure
The drive of the photoconductor is stopped until the scan reaches the specified area, and the exposure scan is continued.
The configuration is such that the photoreceptor is driven when the scan reaches a designated area. According to this, only the specified area of the original is exposed on the surface of the photoreceptor.
be done. Therefore, one copy image forming area of the photoreceptor is sequentially
Form the specified area on the manuscript, and then transfer it all at once.
You can get one edited copy by doing this.
This results in a significant reduction in the number of copy cycles that must be performed. Ma
In addition, combinations such as joining images are mechanically created on the photoreceptor surface.
Because it is done on the screen, you have to change and replace the original many times.
Place the copy that has been transferred and fixed in the paper source again each time.
Even if the exposure cycle is repeated several times without setting the
Only one copying and fixing cycle is required, and there is little image shift. For example, from the manuscript shown in Figure 11, Figures 12a and 12
A copy of the form shown in Figure b or Figure 12c is transferred and fixed once.
You can get it by wearing a cycle. Also, Figure 13a and
From the manuscript shown in Figure 13b to Figure 14a or 14b
The copies shown can also be obtained in one transfer and fixing cycle.
It is possible to re-set the same recording paper to the paper source many times or to perform the fusing process.
Because there is no reason, the image may be misaligned, the paper may be stretched, or there may be wrinkles.

The work of the pelleter is reduced. By stopping and controlling the drive of the photoconductor in this way, the original scanning

During this time, the charging means and transfer means are deenergized to keep the photoreceptor static.

No injuries will occur, and the light from the photoreceptor will be prevented.
It will be done. Furthermore, when the photoreceptor is stopped and driven as described above,

Since the recording paper is also sent to the fixing device from the area where the transfer has been completed,

When the rollers are stopped, the recording paper becomes overheated and discolored.
However, the operating conditions of the fuser roller may be different, causing an abnormality in the fuser unit.
Easy to use. Such problems occur between the transfer unit and the fuser.
, this can be solved by placing the distance longer than the maximum length of the recording paper.

Image editing is performed on the 1-copy image forming area of the photoreceptor.
This reduces image misalignment and reduces copy editing.
This also reduces the number of tasks required by the operator. In addition to this, in the present invention, when the photoreceptor is stopped,
turns off the main charger and transfer charger
Therefore, when the photoconductor is stopped, these chargers should be in position.
The surface of the photoconductor that has been exposed will not be affected by static electricity, and there will be no black streaks on the background.
This is prevented.
