Operating under the control of the CPU 10, it performs various image processing such as image scaling processing, and also performs various image processing such as erasing processing of a binding portion and a frame portion, which will be described later, and setting of a reading range.

The image memory 5 is formed of a RAM or a hard disk and temporarily stores image data read by the scanner 2.

The operation display unit 6 includes various keys necessary for operating the copying apparatus 1 and a display (for example, a liquid crystal display) and an LED (Light Emitting D).
iode) and a copy device 1 from the operation keys.
Various operations required for copy processing using, and whether or not to delete the bound part and frame part as described later, whether to perform the scaling process, and various operations required for the bound part and frame part deletion processing Is performed on the display, and the contents of the command input from the operation keys and various information notified from the copying apparatus 1 to the operator are displayed.

The DMA transfer processing unit 7 converts the image data into a CP

Access) performs various control processes at the time of transfer, and at the time of transfer of the image data, converts the image data (pixel data) at the vertical erasure position set by the CPU 10 into white data, as described later, so that the binding portion And erase the frame part.

The parameter memory 8 stores parameters necessary for various controls of the copying apparatus 1 and is backed up by the battery 9 and retains the stored contents even when the power of the copying apparatus 1 is turned off.

The ROM 11 stores in advance a basic program of the copying apparatus 1, a program for erasing a binding portion and a frame portion, which will be described later, and various data necessary for executing these programs.

The CPU (control means) 10 controls each part of the copying apparatus 1 based on a program in the ROM 11,
The basic processing as the copying apparatus 1 is performed, and the binding part and the frame part are deleted.

The copying apparatus 1 transfers the image data read by the scanner 2 to the image processing section 4 under the control of the DMA transfer processing section 7 and performs image processing on the image data. Transfer to 5. Then, the copying machine 1
Is used to transfer the image data in the image memory 5 to the DMA transfer processing unit 7
Is transferred to the plotter 3, and the plotter 3 records an image on a recording sheet.

The image reading device 1 transfers the image data from the scanner 2 to the image processing unit 4, the image memory 5 and the plotter 3 under the control of the DMA transfer processing unit 7 while converting the image data by the image processing unit 4 to white. Convert to data,
When the A transfer processing unit 7 transfers the image data to white data when transferring the image data from the image processing unit 4 to the image memory 5, the binding unit and the frame unit are deleted. Therefore, the image processing unit 4, the DMA transfer processing unit 7, and the CPU 10 function as an erasing unit as a whole.

The image reading apparatus 1 erases the bound portion and the frame portion according to the selection with the operation keys of the operation display section 6 based on the original document and the recording paper standard. The binding portion and the frame portion are erased by the vertical erasing method.

The erasing of the frame portion and the binding portion on the basis of the document are performed by erasing the frame portion and the center portion (binding portion) of the document based on the set document. Therefore, even if the size of the document and the size of the recording paper are different, what is erased is the frame portion and the center portion of the document, and the erased portion protrudes from the recording paper or, conversely, many portions are erased. Sometimes. However,
Since the original is used as a reference, erasing the center portion of the original and the shaded portion of the frame portion is effective even if the original size and the recording paper size do not match.

In the frame portion erasure and the binding portion erasure based on the recording paper, the frame portion and the center portion of the recording paper are erased based on the recording paper selected at the time of recording the image. Therefore, even if the size of the document and the size of the recording paper are different, what is erased is the frame portion and the center portion of the recording paper, and the erased portion protrudes from the recording paper and the margin is It doesn't get much. However, when erasing the hidden portion of the document, the intended position may not be able to be deleted unless the size of the document and the size of the recording paper match.

Further, the above-described horizontal erasing is for erasing a binding portion and a frame portion in the main scanning direction.
A reading unit (CCD, etc.) for the scanner 2 to read the image of the document
In the case where an image of a document is read in the sub-scanning direction by moving the traveling body on which the is mounted with a step motor in the sub-scanning direction, the reading position in the sub-scanning direction is managed by managing the number of steps of the step motor Of the image data of the original read by the scanner 2 and transferred to the image processing unit 4, the image data of the set frame portion or binding portion in the horizontal direction (main scanning direction) is converted into white by the image processing unit 4. It is erased by converting it to data.

In the vertical direction erasure, a binding portion and a frame portion are erased in the sub-scanning direction. A pixel position to be erased is calculated from an erasing position and an erasing width set before the start of reading, and the erasing is performed. The position of the pixel to be erased is determined by the DMA transfer processing unit 7.
When the DMA transfer processing unit 7 transfers the image data from the image processing unit 4 to the image memory 5, the image data at the pixel position to be erased is replaced with white data and transferred, so that the binding portion and Erase the frame part.

In the copying apparatus 1, since there are cases where both the erasing of the bound portion and the erasing of the frame portion are performed, three areas for replacing the image data with the white data can be set.

Next, the operation of the present embodiment will be described. The copying apparatus 1 erases a bound portion and a frame portion based on a reference selected from a document reference and a recording paper reference, and performs erasing by a method selected from a horizontal deletion and a vertical deletion. Has its features.

That is, the copying apparatus 1 sets the book-type original on the scanner 2 and selects whether or not to erase the frame portion and the bound portion, and determines whether to erase based on the original document or the recording paper. When a selection operation and a selection operation of erasing in the horizontal direction or the vertical direction are performed,
In accordance with the selection operation, a process of deleting the frame portion and the binding portion is performed.

Hereinafter, the selection operation by the operator and the erasing process of the frame portion and the binding portion of the copying apparatus 1 according to the selection operation will be sequentially described.

First, the selection operation by the operator will be described with reference to FIG. When copying an original by the copying apparatus 1, the operator sets the original on the scanner 2 as shown in FIG. 2 (step S1), and selects the recording paper on which the original is to be recorded using the operation keys of the operation display unit 6. (Step S2). The selection of the recording paper determines the size of the recording paper on which the image of the document is to be recorded.

Next, the operator selects a magnification ratio using the operation keys of the operation display section 6 (step S3). In addition,
Normally, the copying apparatus 1 is set to the same-size copying as an initial setting. Therefore, when copying at the same size, the operation keys are not operated.

Next, the operator selects whether or not to perform center erasure (binding part erasure) using the operation key of the operation display unit 6 (step S4). An input is made using the operation keys of the operation display unit 6 (step S5).

Next, the operator selects an erasing direction for center erasing, that is, whether to perform horizontal erasing or vertical erasing (step S6), and determines whether to perform frame erasing. The selection is made using the operation keys on the display unit 6 (step S7). If the center erasure is not performed in step S4, the process proceeds to step S7 to select whether or not to perform frame erasure.

That is, the erasing of the center portion can be performed by only one of the erasing method of the horizontal direction and the erasing in the vertical direction.
It is possible to select between horizontal erasure and vertical erasure.

Next, when the operator selects to delete the frame in step S7, the operator selects whether or not to change the erasure width in accordance with the magnification by using the operation keys of the operation display unit 6 (step S8). ), A frame erasing width is input using the operation keys of the operation display unit 6 (step S9).

Next, the operator performs an operation of selecting whether to erase the frame based on the document or the recording paper using the operation keys of the operation display unit 6 (step S10), and operates the start key to perform the operation processing. (Step S1)
1). If the user selects not to erase the frame in step S7, the process proceeds to step S10, where the user selects between the original reference and the recording paper reference (step S10), and operates the start key to start copying. (Step S11). When the center erasure is not performed and the frame erasure is not performed, the operation of selecting between the original reference and the recording paper reference is not performed.

In the operation of the copying apparatus 1, the operation guide information for guiding the above operations is displayed on the display section of the operation display section 6 in the operation of the operator, so that an appropriate operation can be performed.

Next, the center erasure and frame erasure processing by the copying apparatus 1 in response to the operator's operation will be described with reference to FIG.
It will be described based on.

As described above, the copying apparatus 1 displays appropriate operation guide information on the display section of the operation display section 6 in the operation of the operator, monitors the key operation of the operation display section 6, and operates the scanner. The operation and status of each unit such as the presence / absence of a document set on the document 2 are monitored. Then, as shown in FIG. 3, the copying apparatus 1 executes step S2 in FIG.
When the original is set on the scanner 2, the CPU 10
Is to automatically detect the size of the set document by pre-scanning the document set on the scanner 2 (step P1), and perform various setting / selection operations shown in FIG. Is performed, and when the start key is pressed, the set various setting information is stored in the parameter memory 8 (step P2).

Next, the CPU 10 sets the parameter memory 8
Inspection of the setting information stored in the storage device checks whether center erasure or frame erasure is selected (step P).
3) If it is selected, it is checked whether or not the original reference is selected as the erasure reference (step P4).

If the original reference is selected in step P4, the CPU 10 calculates the original frame position and the original center position corresponding to the designated erase width, and sets the vertical erase position and the horizontal erase position. In step P4, when the recording paper reference is selected instead of the original reference in step P4, the frame position of the recording paper and the center position of the recording paper corresponding to the designated erasing width are calculated, and the vertical position is calculated. An erase position and a horizontal erase position are set (step P6).

That is, when the document reference is selected, the CPU 10 calculates the center erasing position and the frame erasing position from the document size detected in step P1 and the input erasing width.

For example, when the original is an A4 portrait original and the center erasure is to be performed with an erasing width of 20 mm in the case of performing the same-size recording, when the erasing is performed in the horizontal direction, the length of the A4 in the vertical direction is 297 mm. Therefore, the center position is
(297/2) mm = 148.5 mm, which is 20 mm
The horizontal erase position when erasing the center part with the erase width of
From (148.5-20 / 2) = 138.5 mm position to (148.5 + 20/2) = 158.5 mm position. In the case of horizontal erasing, since the length of the A4 horizontal direction is 210 mm, the center position is (210
/ 2) = 105 mm, and the vertical erasure position when erasing the center portion with an erasure width of 20 mm is (105−20 /
2) From the 95 mm position (105 + 20/2) = 115
mm position.

When the erasing method is horizontal erasing, the CPU 10 moves a traveling body on which a reading unit (CCD or the like) for reading an image of the original by the scanner 2 is moved by a stepping motor in the sub-scanning direction. When reading the image in the sub-scanning direction, the number of steps of the step motor is managed, the reading position in the sub-scanning direction is managed, and the original read by the scanner 2 and transferred to the image processing unit 4 is read. The image processing unit 4 is set so that the image data of the center portion of the calculated horizontal erasure position among the image data is converted into white data by the image processing unit 4. CPU1
0 indicates that when the erasing method is vertical erasure, a pixel position to be erased is calculated from the calculated vertical erasure position, and the pixel position to be erased is replaced by white data in the DMA transfer processing unit 7 and the image processing unit 4 is transferred to the image memory 5.

When the erasure reference is not the document reference but the recording paper reference, the CPU 10 calculates the erasure position in the same manner as above using the recording paper size instead of the document size.

Further, the copying apparatus 1 has a scaling function, and can record an image of a document by scaling (enlargement or reduction). In addition to this, as described above,
It is possible to select whether or not the erase width of the frame portion and the center portion is also scaled. When the erasing width is also scaled similarly, the horizontal erasing position can be calculated by multiplying the erasing width by the horizontal erasing position at the same magnification and the erasing width. This is the same as the erasing position in the case of the same magnification, and thereafter, the image data is subjected to the scaling processing of the image
In this case, the erased portion is also scaled. On the other hand, when the image is scaled but the erasure width is not scaled, the horizontal erasure position is the same as the erasure position in the case of the same size, since the magnification is not performed, and the vertical erasure position is The calculation is performed so that the pixel position takes into account the scaling factor when scaling the image data in the image processing unit 4.

For example, when the original is an A4 portrait document and the image data is recorded at a magnification of 110% and recorded, the center erase of 20 mm width is similarly enlarged at a magnification of 110%. Assuming that the horizontal erasure position is to be performed on the basis of the original, the horizontal erasure position is first calculated by the above-described operation processing at the same magnification, and then the calculation is performed in consideration of the magnification. In other words, since the length in the A4 vertical direction is 297 mm, the center position is (297/2) = 148.5 mm, and the center erase width of 20 mm is changed by 110%, so that the erase width is 20 × 1. .1 = 22 mm, and the horizontal erase position is {148.5-[(20/2) × 1.1]} = 13
From 7.5 mm to $ 148.5 + [(20/2) × 1.
1]｝ = 159.5 mm.

At the time of the vertical erasing position, since the length in the A4 horizontal direction is 210 mm, the center position is
(210/2) = 105 mm, and the erase width of 20 mm is changed by 110%. Therefore, the vertical erase position when erasing the center portion with the erase width of 22 mm is {105-[(20
/2)×1.1]}={105+ from the 94 mm position
[(20/2) × 1.1]｝ = 116 mm position.

When the erasing method is horizontal erasing, for example, the scanner 2 moves a traveling body on which a reading unit (CCD or the like) for reading an image of the original is mounted by a stepping motor in the sub-scanning direction. When reading the image in the sub-scanning direction, the number of steps of the step motor is managed, the reading position in the sub-scanning direction is managed, and the original scanned by the scanner 2 and transferred to the image processing unit 4 is read. The image processing unit 4 is set so that the image data of the center portion of the calculated horizontal erasure position among the image data is converted into white data by the image processing unit 4.

When the erasing method is vertical erasing, the CPU 10 calculates a pixel position to be erased from the calculated vertical erasing position and assigns the pixel position to be erased to the DMA.
The transfer processing unit 7 is set so that the data is replaced with white data and transferred from the image processing unit 4 to the image memory 5.

When the erasure standard is not the original standard but the recording paper standard, the CPU 10 calculates the erasure position using the recording paper size instead of the original size and performs the same magnification as described above. The erase position in the case is calculated.

When only the center erasure is selected by the operator operation in FIG. 2 and the frame erasure is not selected, the CPU 10 needs the center erasure by the erasure method selected in the operation processing in FIG. Only the erase position is set, and the erase position of the other erase method is not set.

That is, when only the center erasure is selected and the frame erasure is not selected, when the horizontal erasure is selected as the erasure method, the CPU 10 sets only the calculated horizontal erasure position and executes the erasure. When the vertical erasure is selected as the method, only the calculated vertical erasure position is set. When the frame erasure is also selected, the calculated horizontal erasure position and vertical erasure position of the frame are set.

As described above, when the setting of the erase position is completed in step P5 or step P6, the CPU 10
Sets the other reading parameter memory necessary for the copying operation, and starts the reading process by the scanner 2 (step P8).

When the reading process by the scanner 2 is performed, the CPU 10 converts the image data read by the scanner 2 into a DM.
Under the control of the A transfer processing unit 7, the scanner 2 transmits the image to the image processing unit 4.
After the necessary image processing is performed by the image processing unit 4, the image processing unit 4 transfers the image data to the image memory 5 under the control of the DMA transfer processing unit 7.

In the image processing in the image processing section 4, when the horizontal erasure is selected as the erasure method of the center erasure, the image processing section 4 sets the image data at the horizontal erasure position of the center portion and the frame portion. Is converted to white data, center erasure and frame erasure are performed, and the DMA transfer processing unit 7
When the image data is transferred from the image processing unit 4 to the image memory 5 and the vertical erasing method is selected as the erasing method of the center erasing, the DMA transfer processing unit 7 sets the image at the vertical erasing position of the center portion and the frame portion. The data is converted to white data and transferred to the image memory 5 to perform center erasure and frame erasure.

The CPU 10 transfers the image data having undergone the center erasure and the frame erasure in this manner from the image memory 5 to the plotter 3 under the control of the DMA transfer processing unit 7, and records the image data on the recording paper by the plotter 3. Output.

Therefore, as shown in FIGS. 4 and 5,
On the recording paper 20, image data on which center erasure and frame erasure have been performed is recorded. FIG. 4 shows the recording paper 20 on which an image is recorded when the center part and the frame part are erased with a width of 20 mm, and FIG. The width also shows the recording paper 20 on which an image is recorded when enlarged at a magnification of 200%.

As described above, according to the present embodiment, the bookbinding document having the binding portion is scanned from the image data obtained by the main scanning and the sub-scanning by the scanner 2 and the binding portion and the frame portion around the book-shaped document are read. When converting at least one of the parts into white data over a predetermined erasing width and erasing the white data and recording it on the recording paper 20, the original reference erasing function for performing the erasing on the basis of the original and the recording paper 20 as a reference. Which of the recording paper reference erasing functions to perform erasing is performed according to the result of the operation performed by the operation display unit 6.

Accordingly, the operator can select between erasing based on the original and erasing based on the recording paper 20. The operator can delete the bound portion or the frame portion based on the operator's intended criterion, and can delete the appropriate bound portion or the frame portion. Erasing can be performed, and the usability of the copying apparatus 1 can be improved.

Further, when the image scaling is designated by the operation display section 6, the copying apparatus 1 causes the image scaling processing to be performed, and deletes the bound portion and the frame portion according to the selection of the operation display section 6. Erasure the width by scaling or equal magnification.

Therefore, when the image is scaled, the operator can select whether the bound portion or the frame portion is to be erased with the scaled erasing width or the size of the image according to the scale of the image. It is possible to erase the binding portion and the frame portion more appropriately, and it is possible to further improve the usability of the copying apparatus 1.
