TECHNICAL FIELD OF THE INVENTION
The present invention relates to a display input operation device provided for an operator to set an instruction regarding an operation of various devices.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in an image forming apparatus, for example, a digital copying machine, a system having the following functions has been proposed. That is, the image of the document input from the scanner is processed by selecting from various image processing functions, and the processed image is output from the printer unit. This is a function that can be subjected to various post-processing and provided as edited material.
Since the operation panel of such a digital copying machine has a variety of functions, the number of keys arranged on the operation panel is large, and the operation panel becomes complicated. I can't say that.
[0003]
In recent digital copiers, keys that are used less frequently among many keys are covered, or keys are also used. However, a display input operation device using a combination of a liquid crystal display unit and a transparent touch panel is still insufficient and is often used recently. For example, it is as disclosed in JP-A-6-35282. Based on the embodiment described here, a conventional technique in a copier equipped with a conventional touch panel will be briefly described.
[0004]
A large amount of information is displayed on the LCD screen (liquid crystal display screen), such as the state of the copying machine, instructions from the operator regarding the copying operation, and messages to the operator from the copying machine. The operator gives a desired operation instruction to the copying machine based on the information. The operator only needs to lightly touch the LCD screen in order to give an instruction regarding a desired operation from the selection instruction button display displayed on the LCD screen. For this reason, a touch panel is arranged on this LCD screen, and the content of the selection instruction button display displayed on the LCD screen is input to the copying machine side.
[0005]
The display content of the LCD screen changes one after another according to an operator's instruction or the operation state of the copying machine. This is in order to minimize the display of the instruction button display irrelevant to the current situation of the copying machine by sequentially switching to the display suitable for the state of the copying machine.
For example, a display screen described in Japanese Patent Application Laid-Open No. 6-35282 has a large number of mode selection buttons (touch panel) around the LCD screen in order to display a large amount of information within a limited display range of the LCD screen. ). By operating the mode selection button, the display on the LCD screen is switched to contents suitable for the mode.
[0006]
With such a configuration, even a first-time user can select a desired mode from the mode selection buttons arranged around the LCD screen, and the copier switches the display interactively thereafter. Meanwhile, the operator can select a desired mode. In this way, a person who uses the copying machine can easily operate the copying machine having various processing capabilities.
[0007]
[Problems to be solved by the invention]
However, even in a copying machine provided with such an input device, the operability is not good, and the display contents displayed on the LCD screen may be difficult to understand.
[0008]
In other words, for those who have a good understanding of copiers, it takes a considerable amount of time and operation to reach the LCD display screen where the desired mode is set. On the contrary, the LCD display screen becomes inconvenient. Further, as another problem, since the LCD display screens are sequentially switched, there is a big problem that the contents of the copy mode set on the previous LCD display screen cannot be understood. For this reason, the operator must return the LCD display screen to the original screen for confirmation, and unnecessary time is required for setting the mode.
[0009]
Further, every time the content of the LCD screen is switched by an instruction from the operation unit, a completely different display content from the previous display screen content is displayed on the LCD screen. Each time, the operator looks at all the displayed contents, understands the displayed contents, and performs the next operation. For this reason, even if the manufacturer intends to set the screen in an easy-to-understand manner, at present, it cannot be an input device with good operability when standing on the side of the operator who uses the screen.
[0010]
Therefore, the present invention provides a display input operation that can be easily understood by a person who has not used a device or a person who has used a device easily and in which an instruction to a desired device can be performed by a simple operation. It is intended to provide a device.
Further, even if the display screen is sequentially switched by the instruction of the operator, the mode instructed by the operator can be confirmed at any time, and each time the screen is switched, the operator's viewpoint is not changed carelessly, so that it is easy to understand. It is an object to provide a display input operation device.
[0011]
[Means for Solving the Problems]
The invention of claim 1, an external view of an operation Target equipment and Table Shimesuru display device, a plurality of operation input unit for setting an operation mode of the screen the operation target device is displayed on the said display device, among the manipulation input unit, and a detection device that detect what the fingers of the operator touched, based on a signal from the detection device, and a display control unit for switching the screen display of the display device, the The display control device, when the operation input unit is operated, erases the external view of the operation target device displayed on the screen of the display device, leaving only the operated operation input unit and a corresponding portion. While displaying a plurality of operation input units related to the operation mode set around the remaining external view, when the operation input unit is operated, an icon corresponding to the operated operation input unit is displayed. that is displayed in the appropriate place in the remaining external view And butterflies.
[0013]
The invention of claim 2 is a display input operation device according to claim 1, wherein said icon also switched the screen display, characterized that you have to maintain the display state.

According to a third aspect of the present invention, in the display input operation device according to the first or second aspect , the display control means can change an interval between icons.
[0015]
According to a fourth aspect of the present invention, in the display input operation device according to the first to third aspects, the display control means can change the size of the icon.
[0016]
According to a fifth aspect of the present invention, in the display input operation device according to any one of the first to fourth aspects, the display control means causes the display device to display a list of displayed icons and operation instruction contents indicated by the icons. It is characterized by the following.
[0020]
In the display input operation device according to the present invention, the operator can visually grasp the operation and the mode setting state in comparison with the device configuration of the operation target, and can respond to the user's own settings by display. You can visually confirm that the settings have been accepted. Even if the screen changes one after another, it is possible to continue to check icons and the like on the display screen without moving the viewpoint, and visually check that the user's own settings on the previous screen are certainly maintained. Further, since the icon is displayed together with the setting of the operation instruction, an environment in which the set person can easily understand the meaning of the icon is provided. Therefore, the copying operation can be performed efficiently by grasping the setting contents.
[0021]
Also, on the basic screen, etc., by directly pressing the icon related to the mode set in the predetermined display area, the detailed settings that can immediately confirm the meaning of the icon or the details of the currently set mode Since it is possible to directly transition to the screen, it is possible to easily understand the contents and change the currently set mode. In this way, the operator can easily set, confirm, and change the operation of the device without feeling uneasy in the operation of the touch panel system with many screen movements.
[0022]

The RADF 16 passes through a transport path for a one-sided document, a transport path for a two-sided document, a transport path switching unit, and each unit so that the scanner unit 20 reads one or both sides of the document according to an operator's selection. It is composed of a group of centers for grasping and managing the state of the document, a control unit, and the like. Since many applications and commercializations of the RADF 16 have been made, further description is omitted.
[0026]
A scanner unit 20 constituting the scanner unit 11 for reading an image of a document on the document table 15 includes a lamp reflector assembly 21 for exposing the surface of the document and a reflected light image from the document to a photoelectric conversion element (CCD 24).

[0027]
The scanner unit 11 moves the scanner unit 20 along the lower surface of the document placing table 15 while sequentially placing documents to be read on the document placing table 15 by the related operation of the RADF 16 and the scanner unit 20. It is configured to read a document image. In particular, the first scanning unit 20a travels along the document table 15 from left to right at a constant speed V, and the second scanning unit 20b moves at a speed of V / 2 with respect to the speed V in the same direction. Is controlled in parallel with the scanning. As a result, the image of the document placed on the document placing table 15 is sequentially formed on the CCD 24 line by line, and the image is read.
[0028]
Image data obtained by reading the document image by the scanner unit 20 is sent to an image processing unit described later, and subjected to various processes. Thereafter, the image is temporarily stored in the memory of the image processing unit, and the image in the memory is read out according to the output instruction and transferred to the laser printer unit 12 to form the image on the recording sheet. The laser printer unit 12 includes a sheet conveying system as a recording material for forming an image, a laser writing unit 26, and an electrophotographic processing unit 28 for forming an image.
[0029]

[0032]
(Circuit description of image processing unit)
Next, a configuration and a function of an image processing unit that performs image processing on the read document image information in the digital copying machine 10 will be described.
[0033]
FIG. 2 is a block diagram of an image processing unit included in the digital copying machine 10 of FIG. The image processing unit includes an image data input unit 40, an image processing unit 41, an image data output unit 42, a memory 43 including a RAM (random access memory) and a hard disk, and a central processing unit (CPU) 44. .
[0034]
The image data input section 40 includes a CCD section 40a, a histogram processing section 40b, and an error diffusion processing section 40c. The image data input unit 40 converts the image data of the original read from the CCD 24 into a binary value, processes the image data by an error diffusion method while obtaining a histogram as a binary digital amount, and temporarily stores the image data in the memory 43. It is configured to memorize. That is, in the CCD unit 40a, after an analog electric signal corresponding to each pixel density of image data is A / D converted, MTF correction, black and white correction or gamma correction is performed, and a 256-level (8-bit) digital signal Is output to the histogram processing unit 40b.
[0035]
In the histogram processing unit 40b, the digital signal output from the CCD unit 40a is added for each pixel density of 256 gradations to obtain density information (histogram data). If necessary, the obtained histogram data is sent to the CPU 44. It is sent to the error diffusion processing unit 40c as pixel data.
[0036]
In the error diffusion processing unit 40c, the 8-bit / pixel output from the CCD unit 40a is processed by an error diffusion method, which is a kind of pseudo intermediate processing, that is, a method of reflecting a binarization error in the binarization determination of an adjacent pixel. Is converted into one bit (binarized), and a redistribution calculation is performed to faithfully reproduce the local area density in the document.
[0037]
The image processing section 41 includes multi-value processing sections 41a and 41b, a synthesis processing section 41c, a density conversion processing section 41d, a scaling processing section 41e, an image processing section 41f, an error diffusion processing section 41g, and a compression processing section 41h. I have.
[0038]
The image processing unit 41 is a processing unit that finally converts the input image data into image data desired by the operator, and until the image data is stored in the memory 43 as the finally converted output image data. Is configured to be processed. However, the above-described processing units included in the image processing unit 41 function as needed, and may not function. That is, in the multi-value processing units 41a and 41b, the data binarized by the error diffusion processing unit 40c is converted again into 256 gradations.
[0039]
In the synthesis processing unit 41c, a logical operation for each pixel, that is, an operation of a logical sum, a logical product, or an exclusive logical sum is selectively performed. The data to be subjected to this calculation is the pixel data stored in the memory 43 and the bit data from the pattern generator (PG). The density conversion processing unit 41d arbitrarily sets the relationship between the input density and the output density for the 256-level data signal based on a predetermined tone conversion table.
[0040]
The scaling unit 41e performs interpolation processing with the input known data in accordance with the designated scaling factor, thereby obtaining pixel data (density value) for the target pixel after scaling, and changing the sub-scanning. After the multiplication, the main scanning is scaled. In the pixel processing unit 41f, various image processing may be performed on the input pixel data, and information collection on a data sequence such as feature extraction may be performed. The error diffusion processing unit 41g performs the same processing as the error diffusion processing unit 40c of the image data input unit 40. The compression processing unit 41h compresses the binary data by encoding called run length. As for the compression of image data, the compression functions in the final processing loop when the final output image data is completed.
[0041]
The image data output unit 42 includes a restoration unit 42a, a multi-value processing unit 42b, an error diffusion processing unit 42c, and a laser output unit 42d. The image data output unit 42 restores the image data stored in the memory 43 in a compressed state, converts the image data back to the original 256 gradations, and generates an error of the quaternary data which is a smoother halftone expression than the binary data. It is configured to perform diffusion and transfer data to the laser output unit 42d.
[0042]
That is, in the restoration unit 42a, the image data compressed by the compression processing unit 41h is restored. The multi-value processing section 42b performs the same processing as the multi-value processing sections 41a and 41b of the image processing section 41. The error diffusion processing unit 42c performs the same processing as the error diffusion processing unit 40c of the image data input unit 40. In the laser output unit 42d, digital pixel data is converted into a laser on / off signal based on a control signal from a sequence control (not shown), and the semiconductor laser in the laser writing unit 26 is turned on / off, and An electrostatic latent image is written on the drum.
[0043]
The data handled by the image data input unit 40 and the image data output unit 42 is basically stored in the memory 43 in the form of binary data in order to reduce the capacity of the memory 43. It is also possible to process in the form of quaternary data in consideration of deterioration.
[0044]

[0053]
(One Embodiment of Input Device with Touch Panel)
FIG. 5 shows the liquid crystal display device 56 of the operation panel 45 of the digital copying machine 10 described in FIG. 4 in detail.
The liquid crystal display device 56 includes a liquid crystal display unit 100 of a dot matrix and a touch panel 101 arranged so as to cover the surface thereof. The touch panel 101, which is a means for detecting the position touched by the operator, is larger than the area of the liquid crystal display unit 100. It is also possible to cover a plurality of button groups printed around the liquid crystal display unit 100, and to give an operation instruction to the printed buttons other than the keys displayed on the liquid crystal display unit 100.
[0054]
At the approximate center of the liquid crystal display unit 100 having the above configuration, an overall external view 102 of the digital copier 10 including the operation panel 45 is displayed. Briefly describing the external view 102, a main body portion 103 related to image formation is displayed in the upper center portion of the entire external view 102, and a paper output from the digital copier 10 is displayed on the left side of the entire external view 102.

If the screen is a screen for setting the content of the operation instruction (step S5), the instruction content is reset according to the setting of the operator (step S6).
[0057]
Next, a specific display input operation will be described.
For example, when one of the partial external views 103, 104, and 105 of the overall external view 102 shown in FIG. 5 is touched, the CPU 44 shifts to a mode setting screen of the digital copier 10 corresponding to the touched external view. FIG. 7 is a screen transition diagram when the external view of the display unit is operated. When the user touches the main body portion 103, the setting screen of the double-sided copy mode is set (FIG. (A)). When the user touches the post-processing device portion 104, the setting screen of the output mode is set (FIG. (B)). When the user touches the device portion 105, a setting screen for selecting a paper size is displayed (FIG. 3C).
[0058]
Hereinafter, the screen display of each mode by the CPU 44 will be described in detail.
[0059]
(Duplex copy mode)
For example, when the main body 103 of the digital copier 10 is operated, the display shifts to FIG. 7A, and the setting screen for the duplex copy mode is displayed. The setting screen of the double-sided copy mode is shifted even if a double-sided copy button printed on the left side of the periphery of the liquid crystal display unit 100 is operated.
[0060]
Hereinafter, the screen transition state of the liquid crystal display unit 100 will be described step by step with reference to FIG. In FIG. 8, description will be made in order from the setting screen of the duplex copy mode shown in FIG.
[0061]
As shown in FIG. 8A (same screen as in FIG. 7A), the entire appearance of the operated digital copier 10 is substantially at the center of the liquid crystal display unit 100 which has shifted to the setting screen for the duplex copy mode. Of the 102, only the main body portion 103 remains as it is, and various setting keys related to the duplex copy mode are changed and displayed in other areas. That is, the display of the sheet feeding device portion 104 and the post-processing device portion 105 is turned off, and various setting keys are displayed in the first display area near the main body portion 103.
[0062]
In the above description, a key for finely setting a mode in the first display area, that is, around the main body 103, while maintaining the display position and the display state of the main body 103 substantially in the center of the liquid crystal display unit 100. It is displayed. However, without being limited to this arrangement, the main body 103 may be moved to a slightly different position and displayed, and a key for finely setting a mode may be displayed in the remaining display area. At this time, it is desirable that the display position of the main body portion 103 is not unnecessarily displaced and that the same display form is maintained so as to minimize the confusion of the operator.
[0063]
Here, the keys displayed in the first display area will be briefly described. The key arranged on the left side of the main body 103 is a key 106 for instructing a mode for making a one-sided copy from a one-sided original. This is a normal state before the two-sided copy mode is instructed. From the lower left side of the main body 103, a mode key 107 for making a two-sided copy from an even number of single-sided originals, a mode key 108 for making a two-sided copy from an odd number of single-sided originals, and a mode for making a two-sided copy from a two-sided original A key 109 and a mode key 110 for creating a two-sided copy from a two-sided original are arranged. In each key, an icon indicating the content of the key operation instruction is displayed.
[0064]
When processing a single-sided document, it is sometimes unclear whether the number of documents is an odd number or an even number. In this case, the document count key 111 arranged on the right side of the main body 103 instructs to count the number of document bundles set in the automatic document feeder.
[0065]
When a double-sided mode is selected from the above keys (excluding the single-sided to single-sided mode key 106 and the document count key 111), an icon 112 representing the selected double-sided mode is displayed as an external view of the digital copying machine 10. The information is superimposed and displayed in the main body 103 (FIG. 8B). The area in this external view is the second display area. The icons 112 displayed in the second display area are also superimposed on the icons 112 displayed on the keys 107 for setting the contents of the selected mode in detail, thereby preventing confusion of the operator. it can.
[0066]
In the above description, when a desired mode content is designated from among the setting keys displayed in the first display area (around the main body portion 103 displayed on the liquid crystal display section 100), the second display area (the main body portion 103) is displayed. In the middle, an icon 112 representing the set mode is displayed. However, the operation is not limited to the operation using the touch panel 101 overlaid on the liquid crystal display unit 100, and the operation of a button arranged on an operation panel other than the touch panel 101 causes the icon 112 relating to the set mode to be overlaid on the second display area. It can also be displayed. When the setting of the mode relating to the double-sided copying is completed, the external view 103 of the apparatus displayed on the liquid crystal display unit 100 and the icon 112 relating to the set mode remain as it is, while the overall external view 102 of the digital copying machine 10 remains as it is. Is returned to the display state (FIG. 8C).
[0067]
By displaying the icons in the first display area near the external view 102 of the digital copying machine 10 displayed on the liquid crystal display unit 100 or in the second display area superimposed on the external view 102, The operator can visually grasp what operation is being performed on which part. Therefore, when a plurality of modes are combined and set, the operating environment of the copying system can be easily understood.
[0068]

[0085]
(Explanation of various image editing functions)
The digital copying machine 10 according to the present invention has various image editing functions that can convert read document image information into various forms. A special function key 60 is provided on the operation panel 45 of FIG. 4 in order to select a function desired by the operator from among the various image editing functions. A screen (FIG. 13) for displaying a list of functions and allowing the operator to select an arbitrary editing function is prepared.
[0086]
Each function displayed here will be briefly described.
“Margin” is a function for forming a margin required when filing a sheet. In consideration of double-sided recording, it can be adjusted in 1 mm units in the range of 0 to 20 mm.
“Frame erasing” is a function of automatically erasing a black shadow portion formed on a peripheral portion of a sheet when a book document is copied with the document cover opened. It can be adjusted in 1 mm units within the range of 0 to 20 mm.
“One copy, two copies” is a function of setting a book document in a two-page spread state and reading a document surface of two pages by one copy start instruction.
“Insert cover” is a function for selecting whether or not to insert a cover sheet on the first and last pages of a copy when a document is copied.
The “OHP interleaving paper” controls the supply of paper so that the OHP sheet and the OHP sheet stacked on the paper output tray do not overlap and adhere to each other when copying is performed on the OHP sheet. Things.
“Centering” is a mode in which a document image is recorded at the center of a sheet. For example, when a B5 size document image is recorded on A4 size paper, position adjustment is performed so that the B5 size image is located near the center of the A4 size paper.
“Multi-shot” is a mode in which a plurality of document images are reduced and recorded on one sheet of recording paper. The conversion magnification is determined based on information such as the paper size, the document size, and the number of documents, and the reduced images are collectively edited and output on one sheet.
The “print edit menu” is used to switch to a screen for selecting a function for adding additional information such as a date, the number of pages, a number, and a stamp (urgent, important, circulation) at a predetermined position of a sheet on which a document image is recorded. . The “image editing menu” is a display switching key for displaying a further editing function selection key that is not displayed on the displayed screen.
[0087]
Next, some editing functions, such as the mode setting method when editing and recording the original image using these editing functions, and the icon display method for notifying the operator that the mode has been set, etc., are actually implemented. This will be described. The contents of the display screen, the transition of the display contents, the mode setting method while viewing the display screen, and the like used in the description are merely examples, and partial changes and changes of the display contents are possible.
[0088]
As an example of the editing operation, consider a copy using a combination of the “one set, two copies” mode and the “frame erase” mode. Two-page spread book originals are set on the original glass surface, images of two pages of the book original are output on two separate sheets, and unnecessary shadows of images recorded on each sheet are automatically erased. This case will be described with reference to the screen transitions shown in FIGS.
[0089]
First, FIG. 14 will be described. While the basic screen (A) shown in FIG. 14 is displayed on the liquid crystal display unit 100 arranged on the operation panel 45, the special function key 60 arranged near the upper left of the liquid crystal display unit 100 is operated.

Then, from a plurality of selectable functions displayed on the special function selection screen (B), a desired frame erase function key 120 is operated to select a frame erase mode. At this time, although not shown, the portion of the frame erasure function key 120 is temporarily inverted in black and white, and then the screen is changed to a frame erasure function detailed setting screen (C).
[0090]
Here, when the operator temporarily presses the touch panel in the area of the frame erasing function key 120, the frame erasing function key 120 is inverted between black and white, and it is possible to visually inform that the frame erasing mode is selected. . Further, it is more effective to generate an electronic sound or the like together with the black and white reversal of the display.
[0091]
When the frame erase key 120 is operated, a dedicated icon 121 indicating that the frame erase function has been selected is simultaneously displayed in a predetermined area on the upper left of the display screen of the liquid crystal display unit 100. This icon is displayed at the same time as the operation of the frame erase key 120, and informs the operator that the icon is related to the selected frame erase mode. Therefore, even if an icon remains on the display screen, or remains when a transition is made to another display screen, consideration is given to make it easier to understand the meaning of the icon.
[0092]
In addition, the frame erasing function selected this time includes a frame erasing function that automatically erases the shadow around the paper over a predetermined area width, and a shadow erasing part that can be created when a book original is copied. There is a center erasing function for temporarily erasing and a frame + center erasing function combining these two shadow erasing functions. Here, it is assumed that when the frame erase key 120 is operated, the frame erase mode is selected in a standard state (the frame erase mode key 122 is inverted between black and white). It is also possible to set so that the center erase mode 123 or the frame + center erase 124 is selected first.
[0093]
Further, on the detailed setting screen (C), the mode can be switched by pressing the keys 123 and 124. In order to automatically delete the frame image (shadow) formed around the paper, an input key for setting a deletion area in units of millimeters is provided for each function on the right side of the display screen. Although not given until the drawing number, it is possible to adjust the frame erasing area in the range of 0 to 20 mm in units of 1 mm by pressing the up / down key. FIG. 15 shows a transition state (FIGS. 15 (C1) and (C2)) to the detailed setting screen when the center delete key 123 and the frame + center delete key 124 are operated in addition to the frame delete on the detailed setting screen (C). Respectively.
[0094]
In the detailed setting screen (C) as described above, when the detailed setting of the frame erasing mode is completed, the key 125 for changing the screen arranged in the substantially upper right area of the display screen is operated, and the special screen shown in FIG. The screen is changed to a function selection screen (D). At this time, since the frame erasing mode has been selected, the frame erasing key 120 is inverted between black and white to inform the operator of this.
[0095]
In the detailed setting screen (C), the icon 121 is a dedicated icon displayed to notify that the frame erasing mode has been selected. Even if the display screen of the icon 121 changes from the detailed setting screen (C) to the special function selection screen (D), the display state, position, and the like on the display screen do not basically change. When there is no further selection of a desired special function on the special function selection screen (D), the user closes the special function selection screen (D) and inputs an instruction to transit to the basic screen with the key 126. Then, the display screen transits to the basic screen (E) in FIG.
In the basic screen (E), the position of the icon indicating the selection of the frame erasing mode described above does not basically change from the display position of the previous screen.
[0096]
By operating the screen transition key 125 on the detailed setting screen (C), the screen is temporarily changed to the special function selection screen (D), and then an instruction to change to the basic screen is operated by operating the key 126. Explained. However, in the detailed setting screen (C), it is also possible to directly transition to the basic screen (E) by operating the screen switching key 126 when the setting of the frame erasing mode is completed.
[0097]
Next, FIG. 17 shows a transition of display when one copy of one set of special functions is further selected in addition to the selection of the frame erasing mode described above.
When the special function key 60 on the operation panel is operated again in the state of the basic screen (A) in which the frame deletion icon 121 is displayed, the basic screen (A) transits to the special function selection screen (B). As a matter of course, since the frame erasing mode is selected, the icon 121 is kept at a predetermined display position, and the frame erasing key 120 is in a black-and-white inverted display state. In this state, when the one set 2 copy key 127 is operated from among the special functions, the special function selection screen (B) displays the one set 2 copy key 127 in black and white inverted and the frame erase icon 121 next to it. An icon 128 of one set and two copies is displayed. This state is as shown in the special function selection screen (C).
[0098]
At this time, even if the one-set two-copy mode is selected, there is no particular selection screen, so that the key 127 is inverted between black and white and the icon 128 is displayed in a predetermined area. Is naturally displayed in the same manner as the transition of other screens.
[0099]
When the setting of the mode is completed, the operator operates the key 126 to return to the basic screen (D) again. At this time, the icon 121 of the frame deletion and the icon 128 of one set and two copies displayed on the special function selection screen (C) are not changed so that the display positions are basically unchanged on the basic screen (D). Has become.
[0100]
Next, further points in the embodiment of the present invention will be described.
In the above description, when the icon displayed at a predetermined position on the display unit is directly pressed to indicate that the special function is selected or set, the operation is basically performed from any screen. The detailed setting screen of the mode that the icon means can be displayed again. This function is provided when the meaning of the icon is lost or when the set mode is changed or canceled.
[0101]
For example, in the basic screen (E) of FIG. 16 or the special function selection screen (D), when the icon 121 of the frame deletion displayed near the upper left of the display screen is pressed, the detailed setting screen (C) is displayed on the display screen. Will be displayed again. Then, the operator can check the current setting contents, change the setting as necessary on the display screen, and when the setting change is completed, as described above, the basic screen is sequentially changed thereafter. Only the operation of changing the display screen toward (E) is performed.
[0102]
Next, a method of displaying icons on the operation panel in consideration of operability will be described with reference to FIGS. That is, the display mode of the selected mode or an icon for notifying the operator of the selected mode on the display screen is changed according to, for example, the type of language displayed on the display screen.
[0103]
Here, a method of actually displaying the icons will be described. FIGS. 18A and 19A show a normal display screen in Japanese. (B) and (C) of FIGS. 18 and 19 are display screens in English. (B) shows a case where the interval between a plurality of icons displayed when a plurality of modes is selected is wider than usual. (C) shows the size of the icon itself larger than usual. By changing the interval and size of the icons in this way, the icons are made easier to see and operate.
[0104]
By predicting the race from the type of language and setting the appropriate icon size and spacing according to the characteristics of the body of the race, for example, depending on the size of the finger, mistakenly select the icons other than the icon to be specified By setting not to press, erroneous operation is prevented. In addition, when targeting a person with poor visual acuity, the size is increased to make it easier to see, or the interval is increased to prevent an erroneous operation of touching another part. Thus, a system that is easy for anyone to operate is provided.
[0105]
Also, although not shown this time, when a plurality of modes are set from various modes in a limited display area of the display screen, the icon once displayed basically indicates the position of the display. Do not fluctuate. However, in some cases, the display interval between the icons may be narrower than usual within a limited range and displayed. Thus, a large number of icons can be displayed in a limited display area. As another method, the icon display size may be reduced and displayed within a limited range.
[0106]
Further, in the case where the meaning of the icon displayed at a predetermined position is not understood on each display screen, or when it is desired to confirm the contents of the currently set mode, as shown in FIG. The setting confirmation key 131 is arranged on the left side and below the display screen. When this setting confirmation key 131 is operated, a screen for displaying a list of icons that are actually displayed, function names meaning the icons, setting contents, and the like is displayed on the display screen.
[0107]
When a list of information on these icons is displayed, an icon related to image editing displayed in an area (first display area) near the external view 102 displayed on the basic screen and an area (second display area) overlapping the external view are displayed. By displaying the icons related to the processing for the paper to be displayed in the display area) separately, the mode is set so that the operator can easily confirm the contents of the mode being set by the operator. After confirming the mode contents in this way, the setting contents of the icon can be changed or canceled.
