After performing shading correction and the like on the input image data, the image processing unit 32 outputs the input image data to the main control unit 34 via the scanner interface 33.
The image data is output to the image editing unit 36 or the image recording unit 35 according to the mode of the copying apparatus set to 34. That is, the main control unit 34 outputs the image data from the image processing unit 32 to the image recording unit 35 as it is in the copy mode, and outputs the image data from the image processing unit 32 to the image editing unit 36 in the edit copy mode. Then, after the image is extracted and edited by the image editing unit 36, the image is output to the image recording unit 35.

The toner is adhered to the photoreceptor 48 on which the electrostatic latent image is formed and developed, and the toner image is transferred and fixed on a recording sheet to perform recording.

In accordance with the program in 52, each unit of the image editing unit 36 is controlled to execute image extraction / edit processing. An error check program described later is also stored in the EPROM2.

In the EEPROM 53, preset image extraction, that is, image coordinate values for extraction are registered, and it is also possible to extract a required image of a document without using the lever 24. RAM54 contains the lever 2
The coordinate value designated by 4 is registered and used not only for extracting an image of the reading area of the document designated by the lever 24 but also as a work area for each parameter of scan / print described later.

The image editing unit 36 is connected to the main control unit 34 via the asynchronous communication interface 61, and is connected to the main control unit 34 and the asynchronous communication interface adapter 60.
The control signal is exchanged between the main controller 34 and the controller to exchange image data. The serial image data transferred from the main control unit 34 is converted into parallel image data by the P / S converter 59, and is stored in the FIFO memory. Sent to 58.

The image data sent to the FIFO memory 58 is sequentially stored in the RAM 57. At this time, the P / S converter 59 sends the FIFO memory 58
The DMA controller 55 controls so that only the line data of the reading area of the document specified by the lever 24 among the image data sent to the
Further, the DMA controller 55 requires the RAM controller 56 to store only the image data in the main scanning direction of the reading area of the document specified by the lever 24 among the image data stored in the FIFO memory 58 in the RAM 57. Give control signal.

Data necessary for the image extraction performed by the DMA controller 55 described above is analyzed as coordinate data designated by the lever 24 from the image data sent from the main control unit 34, and stored in the RAM 54. DMA controller
The data of the RAM 54 is given to 55. The RAM 57 has a capacity for storing at least one page of image data (a so-called “page memory”), and the extracted image data stored in the RAM 57 is stored in accordance with the edited image address given to the DMA controller 55 described above. , DMA controller 5

As described above, the program for extracting and editing the image data is stored in the EPROM 52, and the necessary data for editing is stored in the EEPROM 53 and the RAM 54 in advance.

The edited image data transferred from the image editing unit 36 to the main control unit 34 is sent to the image recording unit 35, and is recorded as an image on recording paper.

When using this apparatus, the operator specifies the column to be extracted on the manuscript and starts the apparatus. There are two types of specification methods for obtaining a desired copy. May be.

(1) Fixed Extraction The type of the original to be edited and the coordinate data of each column based on the distance from the scanner reading origin are stored and stored in advance in a dedicated program in association with the keys on the panel,
At the time of editing, the one specified by the key input.

(2) Lever removal A document to be edited is placed on the scanner surface and designated using a lever set in parallel with the sub-scanning direction. The lever position is recognized before the original extraction. The number of levers is usually four, and it is possible to specify two extraction areas.

The operation of the present embodiment configured as described above will be described below.
This will be described with reference to the flowchart shown in FIG.

Now, consider a case where a sample output image as shown in "output" is created from an "original" as shown in FIG. The operator sets the document on the contact glass 21 and
Specify the reading area of the document. This reading area is
As shown in FIG. 9, the present embodiment is characterized in that the margin (Y) in the sub-scanning direction in the region including the boundary is larger than that of the conventional system (see FIG. 8).

When the read area is input (step 11), the internal program stores the read area in a not-shown sampling parameter (sampling position designation information) table, and then determines in step 12 whether M1 + W1 ≧ M2 holds. Check if not.

If the above equation does not hold, the reading areas have no overlap, so that scanning is performed using the specified extraction parameters as they are as scan parameters (scan position specification information) (steps 19 and 14).

On the other hand, when the above equation is satisfied, the read areas have overlaps. Therefore, in step 13, a scan parameter W1 'of W1' = M2-M1 is created, and scanning is performed using this (step 14). FIG. 10 shows the relationship between the sampling parameters and the scan parameters described above.

Next, at the time of print output, output is performed according to the input print parameters PM1 and PM2 in units of sub-scanning lines. This will be described with reference to FIG. First. The print parameter PM2 is significantly different depending on whether the output mode has a block interval (see FIG. 8) or a block interval (see FIG. 7).

However, in processing, the print parameters described above
PM2 differences are treated collectively.

That is, when print parameters are input (step 15), the internal program checks in step 16 whether PM1 + W1 ≧ PM2 is satisfied.

If the above expression does not hold, it means that the output mode is as described above or the output area has no overlap. Therefore, if the output of the address of the page memory (RAM 57) to the end of W1 is W2
Control is performed so as to switch to the beginning (steps 20 and 18).

On the other hand, if the above equation is satisfied, the output areas have an overlap, and a print parameter W1 ″ such that W1 ″ = PM2−PM1 is created in step 17. Next, when only the above W1 ″ is output from the head of PW1 at the address of the page memory (RAM 57), control is performed so as to switch to the head of W2 (step 18).

That is, in the apparatus of the present embodiment, it is possible to output to any of the above or the above output modes by setting the print parameters PM1 and PM2.

In the above-described embodiment, a high-speed FIFO memory having a capacity for one scanning line is provided in order to extract an image in units of sub-scanning lines of the scanner. That is, by executing the internal cycle at a higher speed than the data input / output cycle with the print / scan unit, an empty cycle is created between one line, and this empty cycle is used.
By changing the address of the page memory (RAM 57) set in the DMA controller 55 by the CPU 51, image extraction in line units is realized. In this situation,
This is shown in FIG.

It should be noted that the above embodiment is shown as an example, and the present invention should not be limited to this.
