FIG. 4 shows a detailed configuration of an electronic sorter including the control unit 109 and the hard disk 108 shown in FIG.
In FIG. 4, an image sent from the main body 101 is input as luminance data and sent to a log conversion unit 401. The log conversion unit 401 stores an LUT (lookup table) for converting the input luminance data into density data, and outputs a table value corresponding to the input data, thereby converting the luminance data into density data. Convert to

Thereafter, the density data is sent to the binarizing section 402. The binarization unit 401 binarizes the multi-value density data, and the density value becomes “0” or “255”. The binarized 8-bit image data is “0” or “1”.
Is converted to 1-bit image data, and the amount of image data stored in the memory is reduced.

However, when an image is binarized, the number of gradations of the image is changed from 256 gradations to two gradations. Therefore, binarization of image data having a large number of halftones such as a photographic image generally deteriorates the image. Remarkable. Therefore, it is necessary to perform pseudo halftone expression using binary data. Here, an error diffusion method is used as a method for pseudo-halftone expression using binary data. According to this method, if the density of a certain image is larger than a certain threshold value, it is determined that the density data is “255”, and if the density of the image is equal to or less than a certain threshold value, it is determined that the density data is “0”. In this method, the difference between the actual density data and the binarized data is distributed to surrounding pixels as an error signal.

The distribution of the error is performed by multiplying a weighting coefficient on a matrix prepared in advance by the error generated by the binarization, and adding the result to the surrounding pixels.
As a result, the density average value of the entire image is stored, and the halftone can be represented in a pseudo binary manner.

The binarized image data is supplied to the control unit 403
Sent to Also, input from an external I / F processing unit,
Since the image data from the computer has been processed as binary image data by the external I / F processing unit, it is sent to the control unit 403 as it is. The control unit 403 stores an image of a document to be processed by a computer in accordance with a command from the main body in the image storage unit 4.
04 (corresponding to 108 in FIG. 1).
The image data is sequentially read from the image storage unit 404 and output.

The image storage unit 404 has a SCSI controller and a hard disk (memory), and writes image data to the hard disk 108 according to a command from the SCSI controller. The image data for a plurality of pages stored in the hard disk 108 is output in an order according to the editing mode specified by the operation unit of the copying machine. For example, in the case of sorting, the document is read in order from the last page of the bundle of documents to the first page from the DF, and is temporarily read from the hard disk 108.
To be stored. Then, the image data of the document once stored is read from the hard disk 108 in order from the last page to the first page, and this is repeated and output plural times. Thereby, it can play the same role as a sorter having a plurality of bins. In addition, since images can be stored, multiple copies can be printed without reading the original multiple times, and when the printing is restarted due to a paper jam, the stored original does not need to be read. .

The image data called from the image storage unit 404 is sent to the smoothing unit 405. In the smoothing unit 405, first, 1-bit data is converted into 8-bit data, and the signal of the image data is set to “0” or “255”.

The converted image data is obtained as a sum of multiplications of a coefficient on a predetermined matrix and density values of neighboring pixels, and is replaced with a weighted average value. As a result, the binary data is converted into multi-valued data in accordance with the density value of the neighboring pixels, and an image quality closer to the read image can be reproduced. The smoothed image data is input to the gamma correction unit 406. γ correction unit 4
In step 06, when outputting the density data, conversion is performed using an LUT in consideration of the printer characteristics, the output is adjusted according to the density value set by the operation unit, and output to the main body 101.

FIG. 5 shows the basic operation of the image input / output device according to the present invention. The processing procedure shown in FIG.
It is stored in the OM 112 and / or the hard disk 108, and is read and executed by the CPU 111 in the control unit 1. The numbers in FIG. 5 represent the steps of this flow.
The description will be made assuming that the paper on which the image input / output device is printed comes out with the printing surface facing upward.

In FIG. 5, at 501, the user operates the operation unit 1.
When the user presses a start button in 502, the copy operation starts. 503
Then, the CPU 111 determines whether or not to perform direct output based on the setting on the operation unit 102. Direct output means printing at the same time as document scanning, and non-direct output means that there is some time lag between the time when document scanning results are once secured in memory and printed.
In the case of non-direct output, printing is performed after all originals have been stored. If it is determined that the user's setting is direct output, one page of the document is pulled in under the control of the CPU 111 in 504, scanning is performed, and the memory (RA
At the same time as inputting an image to M113), printing is performed on paper. At 505, the image stored in the memory is stored in a large-capacity memory such as the hard disk 108.

If the memory itself has a large capacity, this process is not necessary. At 507, the CPU 111 stores information accompanying the image, such as the page number and resolution of the read image. In step 507, the CPU 111 checks whether there is still a document to be read.
Returning to the procedure of 4, the process is continued. If there are no more documents, the printing process is performed under the control of the CPU 111 until the number of copies specified by the operation unit is obtained in step 512.

If it is determined in step 503 that direct output is not to be performed, the CPU 111 reads the image into the memory in step 508, and stores the image temporarily stored in the memory in a large-capacity memory such as a hard disk in step 509. At 510, the CPU 111 stores information accompanying the image, such as the page number and resolution of the inserted image. In step 511, the CPU 111 checks whether or not there is still a document to be read. If there is still a document, the process returns to step 508 to continue the process.
If there are no more originals, print processing is performed under the control of the CPU 111 until the number of copies specified by the operation unit 102 is obtained in step 512. When all printing is performed, the processing procedure ends.

FIG. 6 is an operation flow showing a recovery process performed under the control of the CPU 111 of the image input / output device in the non-direct output according to the present invention. The numbers represent the steps in this flow. 6, when a jam occurs in the document feeding apparatus and the jam is detected, the control in FIG. 6 starts. In step 601, the CPU 111 displays a screen for instructing removal of the paper that has caused the paper jam, as indicated by reference numeral 7-1 in FIG.
And the user removes the paper. C at 602
What kind of recovery does the PU 111 perform?
-2 is displayed. In this example, "from the beginning", "from the middle", and "cancel" are displayed so that the user can select one of them. Further, the CPU 111 reads the last read image from the hard disk 108 and displays it on the operation unit 102. In this example, a paper jam occurs when 34 images are read. The display screen of the operation unit 102 also displays the document image read on the thirty-fourth sheet, and the image shows an example in which a document folded by a paper jam is read.

By displaying the last image read at this stage, the user can easily confirm how many images have been correctly stored. When the user operates the keys of the previous and next items in the display of 7-2 in FIG.
An image 11 is read from the hard disk 108 and displayed before / after the current image instead of the displayed image. This allows the user to specify the range and position of the document of the image that has been successfully read and the image that has not been successfully read.

Even if the image cannot be displayed on the operation unit 102, if the direct output is performed, it is possible to determine whether or not the stored image is accurate by checking the print result. Thereafter, the CPU 111 determines an effective image range in 604. An image like reference numeral 7-4 in FIG. 7 is displayed on the operation unit 102. In this example, since the thirty-fourth image stores an image in which a document is broken due to a paper jam, the user has input 33 as the effective range. If the user has a function of displaying image data on the operation unit 102, the image displayed in the effective range is displayed on the operation unit 102 at this time. Next, in step 605, a damaged item (the position of the number of unsuccessfully read originals) is input. If the document on page 34 is broken and cannot be set in the document feeder, and the document on page 35 also breaks due to a paper jam, the user considers these two images to be damage items, When the number of pages is input, an image indicated by reference numeral 7-5 in FIG. When the user inputs the damaged item page and presses the add button, the original image of the damaged item is
8 is deleted by the CPU 111 (605). When all of the damaged items have been input, the CPU 111 guides the guide of the set of the damaged items (the document that has been unsuccessfully read due to the jam as shown in 7-6 and 7-7 in FIG. 8. When the user operates the OK button to instruct the transport and reading of the original, the CPU 111 transports and reads the original, at which time the normal original reading conditions are changed and the transport is performed under the reading conditions suitable for the jam original. (607) Since the position of the read image of the document has been input before, it is inserted and stored in the hard disk 108 in correspondence with the position of the number of documents.

When the reading of all the originals in which the jam has occurred is completed (610), the position of the number of the originals which have not been read and the message urging the resumption of conveyance / reading are displayed as shown at 7-7 in FIG. Let it. In response to the operation of the OK button (not shown) by the user, the CPU 111 conveys and reads the remaining originals.

When reading of all originals is completed and the read image is stored in the hard disk 108, the CPU 1
11 prints the read image (613).

On the other hand, as the type of recovery, "from the beginning"
Is selected, the image stored in the hard disk 108 is erased, the original is returned to the first page, and then the CPU 111 reads the image and performs printing (image input / output) processing again from the beginning (first sheet). Control (611, 61)
2).

In addition to the above embodiment, the following embodiment can be implemented.

1) In the above-described embodiment, the reading of the remaining documents is restarted after the reading of the document damaged by the jam is completed. However, after the occurrence of the jam,
The remaining documents that have not yet been read are conveyed and read in accordance with an instruction from the operation unit of the user, and after the reading is completed, the documents that have been damaged by the jam can be conveyed and read. In this case, the conveyance and reading of the document damaged by the jam is performed after the reading of all the remaining documents is completed.

2) In the above-described embodiment, the recovery operation in the non-direct mode in which printing is performed after reading all originals has been described. The present invention is also applicable to a direct mode in which reading and printing of a document are performed in parallel. In this case, the storage means stores
Replaces AM113. Since the normal reading process is faster than the printing process, one or more document images are temporarily stored in the RAM 113 while printing is completed. Therefore, by displaying the document image stored in the RAM 113 on the operation unit 102 at the time of occurrence of a jam, the user can know the position of the number of documents that have failed to be read. At this time, it is needless to say that the display of the document of the image is switched between the reading order and the reverse order. When the user designates the position of the unsuccessfully read original from the operation unit 102, the CPU 111 stores the unsuccessfully read image in the RAM 11.
3 can be deleted.

[0057]

As described above, according to the first and tenth aspects of the present invention, the image input / output device side stores the jammed original position and the range of the number of successfully read originals. Of the scanned images
It is possible to determine which image should be discarded (erased).
In addition, by erasing an incompletely read image due to a jam, it is possible to avoid unnecessary printing of an image that has not been successfully read due to a jam.

According to the second and eleventh aspects of the present invention, the position of the number of sheets to be conveyed and the number of sheets to be read can be calculated from the position of the unsuccessfully read original and the range of the successfully read original due to the jam. Resumption can be performed, and conveyance and reading can be restarted from a document position where reading was unsuccessful due to a jam or a document next to a document where reading was unsuccessful due to a jam.

According to the third and twelfth aspects of the present invention, the guide of the conveyance of the original is performed after the completion of the conveyance of all the originals except the unsuccessfully read original due to the jam. The document recovery operation can be performed in parallel with the reading of the document by the apparatus, and finally, the conveyance and reading of the image whose reading has failed due to the jam can be performed.

According to the fourth and thirteenth aspects of the invention, the conveyance of the document is performed prior to the conveyance of the document after the unsuccessful reading due to the jam, so that the conveyance of the document can be performed without changing the arrangement order of the document. Can be restarted from the middle of the original.

According to the fifth and fourteenth aspects of the present invention, since the position of the number of originals at which the originals are restarted and transported is guided, the probability that the user sets the originals in the wrong order is reduced.

According to the sixth and fifteenth aspects of the present invention, by instructing the discarding of the read image of the original, the original can be conveyed and read from the beginning or from the middle as required.

According to the seventh and sixteenth aspects of the present invention, by displaying the image of the read original, the user can determine whether or not the reading of the original in which the jam has occurred is successful.

According to the eighth and 17th aspects of the present invention, the reading order,
By switching the display in the reverse order, even if a jam occurs discontinuously, the position of the document whose reading has not been successful can be known.

According to the ninth and eighteenth aspects of the present invention, since the original in which the jam occurs is often the last original immediately after the occurrence of the jam, this original image is displayed initially.
The number of display switching can be reduced as much as possible.
