Abstract

PURPOSE:To shorten a time necessary for setting and inputting the contents of processing images without giving the sense of incongruity to an operator by displaying only executable contents of processing images simultaneously with contents of processing images already set and inputted on a display part at the time of setting and inputting the contents of processing images. CONSTITUTION:At the time of setting and inputting the contents of processing images, only executable contents of processing images are displayed on the display part simultaneously with the contents of processing images already set and inputted by a display means. Since unexecutable contents of processing images are not displayed at the time of setting and inputting the contents of processing images, the operator can not select it. Therefore, it is evaded that the contents of processing images that the operator completes setting and inputting are deleted because they can not executes. Thus, the sense of incongruity is not given to the operator and the waste of the input time can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Al Industrial Field of Application) The present invention relates to an image forming apparatus such as a copying machine, and more particularly to an image forming apparatus having an image processing function for appropriately changing a document image and forming an image on paper or the like. Regarding.

(b1 Summary of the Invention In summary, the image forming apparatus equipped with an image processing function according to the present invention can perform image processing that cannot be performed by displaying on the display unit those that can be executed simultaneously among a plurality of image processing contents. This prevents the contents from being displayed, thereby making it possible to accurately and easily input settings for image processing contents.

(C) Conventional technology As image forming devices such as copying machines become more multifunctional, there is a double-sided image forming function that forms images on both sides of a sheet of paper, and a compositing function that combines and forms images from multiple originals on a single sheet of paper. Numerous image processing functions, such as an image forming function, a trimming function that forms only an image within a specified range of the original image on paper, and a masking function that forms only an image outside the specified range of the original image. Features are added. In order to perform such an image processing function, for example, when forming a double-sided image, it is necessary to input into the device whether the number of original sheets is an even number or an odd number in order to collate the sheets.
Furthermore, it is necessary to input data specific to each image processing function, such as the need to specify an image range during trimming/masking processing. If a key switch for inputting such data is provided for each image processing function, the operation section will become larger and the cost will increase. on the other hand,
If this is avoided and a single key switch is switched and used so that it can handle input of data related to a plurality of image processing functions, the operation becomes complicated and erroneous operations may occur.

Therefore, in some conventional image forming apparatuses, the operating section includes a display section such as an LCD (liquid crystal display), and guidance for guiding the operator's operations is displayed on the display section. Thereby, the operator can input data related to each image processing function according to the guidance displayed on the display section, and can easily input settings for the image processing content to be executed.

(d) Problems to be Solved by the Invention However, in the conventional image forming apparatus, when selecting the image processing content to be executed, regardless of the image processing content that has been set up to that point, the image forming apparatus can perform the image processing. All processing functions were displayed sequentially. For this reason, image processing contents that cannot be executed in combination with image processing contents that have been set up to that point are also displayed, and the operator may select this by mistake. In this case, after the input of data related to the current image processing function is completed, it is determined that it is impossible to execute it in combination with the previously set image processing function, and the operator is notified that the setting is impossible. This caused the operator to feel uncomfortable (and wasted input time).

An object of the present invention is to prevent the operator from selecting an image processing content by not displaying an image processing content that cannot be executed in combination with the image processing content that has been set and input when manually setting the image processing content. to prevent
To provide an image forming apparatus that is equipped with an image processing function that does not display a message indicating that it cannot be executed after inputting settings for an image processing function that cannot be executed, does not give a sense of discomfort to the operator, and can eliminate wasted input time. It is about providing.

Means for Solving Problem fe1 An image forming apparatus equipped with an image processing function according to the present invention allows setting input of image processing content to be executed from among a plurality of image processing content on a display screen displayed on a display unit. In an image forming apparatus equipped with an image processing function that accepts image processing functions, a display means is provided for displaying only image processing contents that can be executed at the same time as the image processing contents that have already been inputted on the display unit when inputting settings for image processing contents. Features.

([1 Effect] In this invention, when inputting settings for the image processing function,
Only the image processing contents that can be executed simultaneously with the image processing contents whose settings have already been inputted by the display means are displayed on the display section. Therefore, when inputting settings for image processing contents, image processing contents that cannot be executed are not displayed, and the operator cannot select them. Therefore, the image processing contents for which the operator has finished inputting the settings are not canceled as being unexecutable.

Check whether F30 is installed (n
42). If neither the duplex unit nor the RADF 30 is attached, the contents of the display panel 52 are set to the state shown in FIG. 6(A) for the time counted by the timer T, and the process returns to the standby state (n43 to n45→n2). This timer T
is allocated to a predetermined memory area of the RAM 73, and measures a time of about 3 to 5 seconds. If only the RADF 30 is installed, the contents of the display panel 52
The state shown in Figure (F) is established (n52), and the mode is set to copy the image of the double-sided document onto one side of the paper (n53).

As a result, the double-sided original 3 placed on the original tray 32
The images of the front and back sides of 1 are each single-sided copied onto a single sheet of paper.

If the duplex unit is installed, the presence or absence of the RADF 30 is detected (n 46), and if the RADF 30 is not installed, the automatic document feeder (not shown) is detected.
Hereinafter referred to as ADF. ) is attached (n47). This ADF is a device that unilaterally transports the original from the original placement position to the original ejection position via the original platen 2, and unlike the RADF30, it cannot reverse the original and transport it onto the original platen 2 again. . A like this
If the DF is also not installed, the display panel 52
In the state shown in Figure (D), the operator copies the image of the document placed on the document table onto both the front and back sides of the paper. In this case, the copying process is executed each time the print switch is operated by the operator. That is, when the operator operates the print switch after setting an original on the original platen 2, the paper is fed from the paper feeding section. The sheet is directed to intermediate I-lay 26 after the copying process is completed. When the operator replaces the original and then operates the print switch, the paper is guided from the intermediate tray 26 to the copying process section via the sub-conveyance path 29, and the images of the two originals are printed on both the front and back sides of one sheet. are copied respectively.

When the double-sided unit, unit, and ADF are installed, the contents of the display panel 52 are set to the state shown in FIG. 6(C),
An input as to whether the number of original sheets is an even number or an odd number is accepted (n49, n50). Duplex unit and AD
When F is installed, images from a single-sided original can be automatically and continuously copied onto both sides of the paper. In this case, if the number of single-sided originals is an even number, for collation reasons, the first sheet of paper is led to the intermediate tray 26, and if the number of originals is an odd number, the first sheet of the original is imaged. The paper that has been copied is ejected as a single-sided copy, and the second paper is transferred to the intermediate tray 2.
Lead to 6. In this manner, images of two single-sided originals are automatically copied onto both sides of the paper according to the input data on the number of originals.

When both the duplex unit and the RADF 30 are installed as shown in FIG. 2, the contents of the display panel 52 should be changed to the state shown in FIG. mode for copying on both sides of
A selection is accepted between a mode in which images of a double-sided original are copied onto both sides of a sheet of paper, and a mode in which an image of a double-sided original is copied onto one side of a sheet of paper. In this case, the input is level key 56.
The mode is selected by operating the level key 57, and the setting is input by operating the level key 57. If the mode for copying the image of a single-sided original onto both sides of the paper is selected, the contents shown in Figure 6(C) will be displayed (n55-n49), and the mode for copying the image of the double-sided original onto one side of the paper is selected. Figure 6 (
