Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document reading apparatus for reading an image of a document in, for example, a copier or a multifunction facsimile machine, and more particularly, to a shadow generated when a thick document such as a book is read. And a document reading apparatus capable of easily removing the document.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 10, a document reading apparatus 101 such as a copying machine or a multi-function facsimile machine has a transparent document placing plate 102 for placing a document on an upper surface thereof, and The document reading unit 104 includes an image reading unit 103 provided below the mounting plate 102 and reads an image of a document, and a pressing lid 105 provided on the upper surface of the document reading unit 104 so as to be openable and closable.

When a thick original such as a book is read by such an original reading apparatus 101, the peripheral portion of the original may be read black and a shadow may occur. This is because the light from the light source of the image reading device 103 is not reflected and is read as a black shadow because the original is too thick to close the presser cover 105 completely. Further, when the original is a book, the binding portion of the book located at the center in a state where the original is opened and placed on the original placing plate 102 is separated from the original placing plate 102.
In some cases, the binding portion may be similarly read as a black shadow. Such a shadow is unsightly and dirty when a document image is recorded on recording paper. Therefore, conventionally, in order to solve such a problem, when reading a thick original such as a book, the image of the shadow portion is erased from the read image, that is, the black portion of the shadow portion is erased. Shadows have been removed by performing image editing that replaces images with white images.

[0004]

However, in the prior art, the original reading apparatus 101 can automatically recognize whether the original is thick, such as a book, or thin, such as paper. Did not. Therefore,
In order to perform the image editing as described above, set in advance to always perform the image editing, or
When reading a thick original, the user has to perform any one of settings for performing image editing in accordance with the original each time, so that the following problem arises.

[0005] That is, if image editing is set to be always performed, the image is read with the same settings for all the originals, so that a thick original such as a book and a thin original such as paper are read. It is necessary to set the editing area so as to conform to both. However, it is actually difficult to specify such an editing area, and a reading error may occur depending on the type of the document. In particular, if the original is a book, it is desirable to edit the image at the center in the longitudinal direction of the original in order to eliminate the shadow generated at the binding portion of the book. In this case, there is a problem in that it is not appropriate to erase the shadow generated in the binding portion of the book with such a setting, since erasing the image would erase a necessary image in the central portion.

On the other hand, when a user sets a setting for editing an image in accordance with a document each time a thick document is read, an appropriate editing area can be designated according to the document. However, the above problem does not occur. However, every time the user reads a thick original, it is necessary to operate the operation unit 106 to make settings for performing image editing, which causes a problem that the user has to perform complicated operations. is there. Further, since performing such a complicated operation is avoided, there is a problem that the image editing function itself may not be used much in practice.

The present invention has been made in view of the above problems, and easily and appropriately removes a shadow generated when a thick original such as a book is read without a user performing a setting operation. It is an object of the present invention to provide a manuscript reading device capable of performing the above.

[0008]

Means for solving the above problems are as follows. That is, according to a first aspect of the present invention, there is provided a document reading apparatus having a document reading section and a press cover that is openably closable on an upper surface of the document reading section. When a start command is issued, a predetermined image editing is performed on the image read by the document reading unit.

According to a second aspect of the present invention, there is provided a
2. The configuration according to claim 1, wherein the image editing is one or both of erasing a fixed width image at a peripheral portion of the document and erasing a fixed width image at a longitudinal center portion of the document. Things.

Next, the document reading apparatus 1 according to the present embodiment
Will be described with reference to the flowcharts shown in FIGS. FIG. 7 is continuous with FIG. First, the document size is detected as follows. That is, when the presser lid 3 becomes equal to or smaller than the first angle θ1 (S1: YES), it is determined that the user has performed the operation of closing the presser lid 3 and starts reading the document. The size detection sensor 14 operates to start detecting the size of the document (S2). If the document size is a fixed size such as "A3", "B4", "A4", "B5", the size of the document can be detected by the size detection sensor 14 (S2: YE
S).

On the other hand, when the original size is irregular, the original size cannot be detected by the size detection sensor 14 (S2: NO), so that the user needs to input the original size from the operation unit 25. (S3).
If the presser lid 3 is not smaller than the first angle θ1 (S1: NO), the size detection sensor 14 does not operate and the document size cannot be detected. Must be input from the operation unit 25 (S3). Note that the size detection sensor 14 may always operate to detect the document size without performing the determination (S1) as to whether or not the presser lid 3 is equal to or smaller than the first angle θ1.

Next, it is determined whether or not the presser lid 3 is equal to or larger than the second angle θ2 (S4). If the presser lid 3 is equal to or larger than the second angle θ2 (S4: YES), it is determined that the document is to be read with the user holding the presser lid 3 open. In order to remove the frame, it is set so that the frame is automatically erased (S5). On the other hand, when the original is read with the presser lid 3 opened, whether the original placed on the original placing plate 12 is a thick book or an ordinary thin paper original Can not be automatically determined whether or not to delete the center. Therefore, in such a case, it is set in advance whether or not to delete the center. If the setting is to delete the center (S6: YES), the setting is made to automatically delete the center. (S7). If the setting is not to delete the center (S6: NO),
Center erasure is not performed (S8).

If the presser lid 3 is not larger than the second angle θ2 (S4: NO), it is determined that the user closes the presser lid 3 and reads a document. Is greater than or equal to the third angle θ3 (S
9). Here, when the pressing lid 3 is equal to or larger than the third angle θ3 (S9: YES), that is, when the pressing lid 3 is at the second angle θ2.
And the third angle θ3, it is considered that the presser lid 3 is to be closed but cannot be completely closed due to the thickness of the original. It is determined that the original placed in is a thick book, so the frame is automatically erased in order to remove the shadow of the peripheral part of the original and the shadow of the binding part of the book located at the center in the longitudinal direction of the original. Then, a setting is made to perform center erasure (S10).

On the other hand, when the presser lid 3 is smaller than the third angle θ3 (S9: NO), the presser lid 3 is almost completely closed, and is placed on the original placing plate 12. Since the original is determined to be a normal thin paper original, neither frame erasure nor center erasure is performed (S11).

After the frame erasure and the center erasure are automatically determined as described above, the setting state of the determined frame erasure and center erasure is displayed on the display unit 2.
6 is displayed (S12). Here, as for the width of the image area where the frame erasure and the center erasure are performed, a preset value is displayed. For example, as for the frame erasing, the width of the image to be erased from the upper and lower edges and the left and right edges of the document is determined by “up and down: : mm” and “left and right: ○ m”.
m ". The same applies to center erasure. Thereby, the user can confirm the setting state of the frame deletion and the center deletion. Then, when changing the setting of the frame deletion or the center deletion (S13:
YES), the user inputs new settings from the operation unit 25 (S14). The input of the setting at this time includes both the setting of whether or not to perform the image editing for the frame erasure and the center erasure, and the setting of the width of the image area where the frame erasure and the center erasure are performed. If the setting of frame erasure or center erasure has been changed, the process returns to S12, and a new setting state of frame erasure or center erasure is displayed on the display unit 26 (S12).

If the setting of frame erasure or center erasure is not changed (S13: NO), it is determined whether or not the start key 27 has been pressed (S15). If the start key 27 is pressed (S15: YES), it is determined that the reading start command has been issued, and the document reading unit 2 reads the image of the document and stores it in the image memory 41 (S15).
16). If the start key 27 is not pressed (S1
5: NO), the setting state of the frame erasure and the center erasure remains displayed on the display unit 26 (S12).

The start key 27 is pressed (S15: YE)
S), after the image of the document is stored in the image memory 41 (S16), it is determined whether or not the setting for erasing the frame is made (S1).
7). If the setting is to erase the frame (S17: YE
S) Image editing is performed to replace the image in the editing area where the set frame erasure is to be performed with a white image to remove the shadow of the portion (S18). If the setting is not to erase the frame (S17: NO), the frame is not erased.

Next, it is determined whether or not the setting for performing center erasure is made (S19). If the setting is to delete the center (S19: YES), the image in the editing area where the set center is to be deleted is replaced with a white image.
Image editing for removing the shadow of the portion is performed (S20). If the setting is not to delete the center (S19: N
O) Do not erase the center.

As described above, the image data on which the predetermined image editing has been performed is recorded on the recording paper 7 in the recording section 6 so that the shadow generated when a thick original such as a book is read is removed. Can be recorded.

Next, a document reading apparatus 1 according to a second embodiment of the present invention will be described. The document reading apparatus 1 according to the present embodiment has the same configuration as that of the first embodiment, but operates slightly differently.
Is started and the operation starts when a reading start command is issued. Therefore, the description of the configuration of the document reading apparatus 1 according to the present embodiment will be omitted, and its operation will be described below with reference to the flowchart shown in FIG.

First, it is determined whether or not the start key 27 has been pressed (S21). If the start key 27 is not pressed (S21: NO), the operation does not start. When the start key 27 is pressed (S21: YE
S) Next, it is determined whether or not the document size has been detected (S22). In the present embodiment, unlike the first embodiment, the size detection sensor 14 always operates to detect the document size. If the document size is a fixed size, the document size can be detected by the size detection sensor 14 (S22: YES). on the other hand,
If the document size is irregular, the size of the document cannot be detected by the size detection sensor 14 (S22: NO).
(S23).

Next, it is determined whether or not the presser lid 3 is equal to or larger than the second angle θ2 (S24). If the presser lid 3 is equal to or larger than the second angle θ2 (S24: YES), it is determined that the user reads the document with the presser lid 3 opened, so that the shadow of the peripheral portion of the document is cast. In order to remove the frame, a setting is made to automatically erase the frame (S25). On the other hand, when reading a document with the presser cover 3 opened, the document placing plate 1
Since it is not possible to determine whether the original placed on 2 is a thick book or a normal thin paper original, it is not possible to automatically determine whether to erase the center. Can not. Therefore, whether or not to delete the center in such a case is set in advance. If the setting is to delete the center (S26: YES),
Set to automatically delete the center (S2
7). If the setting is not to delete the center (S26: NO), the center is not deleted (S2).
8).

If the press cover 3 is not larger than the second angle θ2 (S24: NO), it is determined that the user closes the press cover 3 to read a document. Is greater than or equal to the third angle θ3 (S2).
9). Here, when the pressing lid 3 is equal to or larger than the third angle θ3 (S29: YES), that is, when the pressing lid 3 is at the second angle θ.
2 and the third angle θ3, it is considered that the presser lid 3 is to be closed but cannot be completely closed due to the thickness of the original.
The original placed on top of the original is determined to be a thick book, so the shadow on the periphery of the original and the shadow on the binding part of the book located at the center in the longitudinal direction of the original are automatically removed. It is set to perform frame erasure and center erasure (S30).

On the other hand, when the presser cover 3 is smaller than the third angle θ3 (S29: NO), the presser cover 3 is almost completely closed and is placed on the original placing plate 12. Since the original is determined to be a normal thin paper original, neither frame erasure nor center erasure is performed (S31).

As described above, after it is automatically determined whether to perform the frame erasure and the center erasure, the image of the original is read by the original reading unit 2 and stored in the image memory 41 (S32). .

Next, it is determined whether or not the setting is to erase the frame (S33). If the setting is to erase the frame (S3
3: YES), image editing for removing the shadow of the set area by replacing the image in the editing area where frame erasure is to be performed with a white image (S34). If the setting is not to erase the frame (S33: NO), the frame is not erased.

Next, it is determined whether or not the setting for performing center erasure is made (S35). If the setting is to perform center deletion (S35: YES), the image in the editing area where the center deletion is to be performed is replaced with a white image.
Image editing for removing the shadow of the portion is performed (S36). If the setting is not to delete the center (S35: N
O) Do not erase the center.

As described above, by recording the image data on which the predetermined image editing has been performed on the recording paper 7 in the recording section 6, a thick original such as a book is read as in the first embodiment. An image can be recorded by removing the shadow generated when the image is formed.
