Abstract

PROBLEM TO BE SOLVED: To provide an imaging device, capable of preventing miscopying caused by placing an original in the state of oblique or deviated from the set position on an original platen. SOLUTION: The device is provided with a reading means for reading the situation of the original 7 placed on the original platen 8, a touch panel (display means) 4 for displaying the placement situation of the read original and a means (operation key) for adjusting the outputted image, while looking at the panel 4. A user can confirm whether the original 7 is placed correctly by looking at the panel 4 for displaying the situation of the original, before the start of copying operation. If the original 7 is not placed correctly, by operating the means (operation key) for adjusting the output image, miscopying resulting in the output image being oblique or outputting the image at a deviated copying position is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a copying machine for allowing a user to check the status of a document stored on a document table and obtain a desired output image.

[0002]

2. Description of the Related Art FIG. 6 is an external view of a conventionally well-known image forming apparatus, and FIG. 7 shows a state in which a document platen of the image forming apparatus is opened and a document is stored on a document table.

In FIGS. 6 and 7, reference numeral 11 denotes an image forming apparatus main body, reference numeral 12 denotes a document pressing plate, and reference numeral 13 denotes an operation unit. Here, details of the operation unit 13 are shown in FIG.

FIG. 8 is a plan view of the operation unit 13, in which 14 is a touch panel, and 15 is a copy start key.

[0005] The image forming apparatus 11 configured as described above.
In the case where the user performs a copy operation, as shown in FIG. 7, after placing the original while checking whether the original is correctly placed on the original platen, the original pressure plate 12 is closed, Depressing the copy start key 15 to perform a copy operation is a general operation so far.

[0006]

However, in the case of the above-mentioned conventional example, it is difficult for the user to determine whether or not the original is correctly placed on the original platen. there is a problem that is output in a state shifted to.

Also, especially thick originals (for example, book originals)
In this case, when the document pressure plate 12 is closed, the document is likely to be displaced, and there is a problem that the output image is also skewed or output in a state where it is displaced forward, backward, left and right.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object thereof is to prevent erroneous copying due to a document being placed obliquely or off the set position on a document table. To provide an image forming apparatus capable of performing the above.

[0009]

According to one aspect of the present invention, there is provided a reading means for reading the status of a document stored on a document table, and a display means for displaying a mounting status of the read document. And means for adjusting the output image while viewing the display means.

[0010] According to a second aspect of the present invention, in the first aspect, if the document is placed at an oblique state on the document table, after pressing a copy start key, it may be continued as it is copied A means for displaying a message as to whether or not the message is provided.

Therefore, according to the first aspect of the present invention, the user can check whether or not the original is correctly placed by looking at the display means for displaying the status of the original before starting the copying operation. You can check. Then, when the original is not placed correctly, by operating the means for adjusting the output image, it is possible to prevent erroneous copying such that the output image is skewed or output with the copy position shifted. be able to.

According to the second aspect of the present invention, it is possible to prevent the user from continuing the copying operation by mistake when the original is not stored correctly.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

<First Embodiment> FIG. 1 is an external view of an image forming apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes an image forming apparatus main body, 2 denotes a document pressing plate, and 3 denotes an operation unit.

FIG. 2 is a plan view showing the details of the operation unit 3, in which 4 is a touch panel, 5 is a copy start key, and 6 is an operation key.

FIG. 3 is a plan view showing a state in which a document is placed on a document table. In FIG. 3, reference numeral 7 denotes a document, reference numeral 8 denotes a document table, and reference numeral 9 denotes a document illumination disposed below the document table 8. It is a lamp.

[0017] In the image forming apparatus 1 configured as described above, if the user closes the document pressing plate 2 after placing the original 7 on the original table 8 by opening the document pressing plate 2, the illumination lamp 9 document 7 Is scanned in the sub-scanning direction, and a CC (not shown) is scanned.
The D sensor irradiates the reflected light of the original 7. As a result, the edge portion of the document 7 in the main scanning direction is read, the placement state of the document 7 is recognized, and this is displayed on the touch panel 4 as shown in FIG.

Here, when the original 7 is placed obliquely, or when the original 7 is displaced from the abutting position, the user operates the operation keys 6 while watching the display on the touch panel 4. To correct the image displayed on the touch panel 4 to an appropriate state. After that, the copy image output when the copy start key 5 is pressed is output while being displayed on the touch panel 4.

Accordingly, the user can confirm whether or not the original 7 is correctly placed on the touch panel 4, thereby preventing erroneous copying.

Even when it is difficult to accurately place the document on the document table 8 such as a thick document such as a book document, the output image is corrected by correcting the image displayed on the touch panel 4 to an appropriate state. Can be solved in a state where the image is output obliquely or the copy position is shifted.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG.

In this embodiment, the user operates the operation keys 6 while looking at the touch panel 4 as in the first embodiment.
To correct the image displayed on the touch panel 4 to an appropriate state, and then press the copy start key 5 to output a copy image. Here, if the image information on the touch panel 4 is shifted from front to back, left and right, or skewed, a warning message shown in FIG. Do you want to continue copying? ”Is displayed on the touch panel 4. In this case, the user can output the copy image by operating the operation key 6 again to adjust again, and pressing the copy start key 5 again to continue copying. It should be noted that the deviation amount of the mm or more at which the warning message is displayed can be adjusted by changing the set value of the image forming apparatus.

[0023]

As apparent from the above description, according to the present invention, reading means for reading the status of a document stored on a document table, display means for displaying the mounting status of the read document, and the display means Since the means for adjusting the output image while viewing the means is provided, it is possible to obtain an effect that it is possible to prevent erroneous copying due to the document being placed obliquely or off the set position on the document table.
