When the copy magnification key 111 is pressed while the change mode is set, a change screen as shown in FIG. 12A is displayed on the display 100. On the display 100, "actual size" is first displayed, and at positions corresponding to the selection keys 101 to 103 in the lower part of the display screen, display positions 101 'to 103' (in the figure) where information on the copy magnification can be displayed. The shaded area) is displayed. The copy magnifications are sequentially displayed on the display screen in the order of “actual size”, “reduction”, and “enlargement”. Here, with respect to the above-mentioned copying conditions, from the left side of the display 100 in the drawing, “reduction”, “actual size”, and “enlargement” are performed.
The case of displaying in the order of will be specifically described.

First, the display position 102 'at the center of "actual size" is displayed.
In order to display at, the selection key 102 corresponding to this display position 102 'is pressed. When the selection key 102 is pressed, FIG.
As shown in 2 (b), "1: 1" is displayed at the display position 102 ', and "reduced" is displayed at the position where "1: 1" was displayed. This "reduction" is displayed at position 10
When the selection key 101 is pressed to display 1 ′, “reduction” is displayed at the display position 101 ′ and “enlarge” is displayed at the remaining display position 103 ′ as shown in FIG.

Each of the flags F1 to F3 corresponds to each of the display positions 101 ′ to 103 ′ (or the selection keys 101 to 103), and is the display position of the display position where “the same size” to be registered first is displayed. Only the flag becomes "1". In the example above,
When "1x" is not displayed in any of the display positions 101 'to 103', the flags F1 to F3 are all "0".
And the flag F2 is displayed at the display position 102 '.
Only becomes "1".

Details of the flowcharts of FIGS. 7 to 11 will be described below.

In steps # 308 to # 312, the mode for changing the display position of the information regarding the copy magnification (hereinafter referred to as the copy magnification display position changing mode) is set and released, and the copy magnification key 111 is pressed. When the copy magnification display position change mode is set by the
The LED 111a is turned on at 310, and as shown in FIG.
The change screen shown in (a) is displayed. On the other hand, when the copy magnification display position changing mode is released, step # 312
The LED 111a is turned off and the standard screen is displayed. When the LED 111a is on and the copy magnification key 111 is not turned on (step # 30).
8: YES, # 311: NO), the process proceeds to step # 313 to continue the process of changing the display position of the copy magnification.

At steps # 313 to # 315, it is determined whether the flags F1 to F3 are set.
If "1x" is not registered in any display position, all the flags F1 to F3 have been reset, so the process proceeds to step # 328 (step # 313: NO, # 3).
14: NO, # 314: NO). Further, when "1x" is already displayed in any of the display positions 101 'to 103' on the display 100 and any of the flags F1 to F3 is set, it corresponds to the set flag. The processing is performed.

Steps # 328, # 330, # 332
Is a step of determining whether or not any one of the selection keys 101 to 103 corresponding to the display position is pressed in order to display the “equal size” information in any of the display positions 101 ′ to 103 ′. is there.

In other words, as in the above-mentioned example, when each piece of information regarding the copy magnification is to be displayed in the order of "reduction", "actual size", and "enlargement" from the left as shown in FIG. 12 (c). The following processing is performed.

The selection key 102 is depressed to display the "equal size" information displayed on the change screen of FIG. 12A at the central display position 102 '(step # 30).
8: NO, # 312: YES, # 313: NO, # 31
4: NO, # 315: NO, # 328: NO, # 33
0: YES), the information of "actual size" is stored in the memory area 2 of the RAM 200 in step # 331, and the flag F2 is set to "1" (see FIG. 12B). Then, the selection key 101 is pressed to display "reduction" at the display position 101 'on the left side (step # 308: N).
O, # 312: YES, # 313: NO, # 314: Y
ES, # 320: YES). Then, step # 321
The information of “reduction” and “enlargement” is stored in the memory areas 1 and 3 of the RAM 200, respectively, and at the same time, the process of resetting the flag F2 is performed (see FIG. 12C). Here, in each memory area of the RAM 200, in addition to the information on the copy condition displayed on the display 100, a control code for calling a program for controlling the main body of the copying machine is stored.

In the above processing, the copy conditions of "reduction", "actual size", and "enlargement" are the same as the memory area 1 of the RAM 200.
It means that they are stored in 2 and 3, respectively. Then, the copy magnification key 111 is pressed again (step # 300: YE).
S, # 303: NO, # 308: YES, # 309: Y
ES), and turns off the LED 111a in step # 310.
At the same time, the standard screen is displayed on the liquid crystal display, and the processing for changing the magnification condition display position ends.

Subsequently, when the display position of the information relating to the copy condition such as the paper size or the image density is changed, the paper size key 112 or the image density key 113 may be pressed. When the paper size key 112 or the image density key 113 is pressed,
Paper size display position routine in step # 305, or
The density display position changing routine of step # 306 is called, and the same processing as the magnification condition display position changing routine is executed.

FIG. 13 is a flow chart showing the processing procedure of the copy magnification setting mode of step # 4. FIG. 14 is a standard screen after setting a desired copy magnification, and FIGS. 15 and 16 are setting screens for setting copy magnification. In step # 400, it is determined by the flag FMS whether or not the copy magnification setting mode is set. This flag FMS is
This is a flag which becomes "1" when the copy magnification key 111 is pressed when the flag FC is "0".

First, when the flag FMS is not "1" (step # 400: NO), it is determined in step # 403 whether the flag FC is "0". If the flag FC is not "0" (step # 403: NO), the copy magnification display position change mode is currently set, so the copy magnification setting process is not performed. If the flag FC is "0" (step # 403: YES), it is determined in step # 404 whether or not the copy magnification key 111 is pressed. When pressed (Step # 404: YE
S) turns on the LED 111a and sets the flag FMS to "1" in step # 407. Step # 407
After the flag FMS is set to "1" in step # 408, it is determined in step # 408 whether or not the above-described processing for changing the display position of the copy magnification is executed, and if it is executed (step # 408: YES). If the copy magnification setting screen (see FIG. 16) after the display position is changed is displayed in step # 409 on the display 100 and is not executed (step # 408: NO), the display position is changed in step # 410. A copy magnification setting screen (see FIG. 15) is displayed. It should be noted that the determination as to whether or not the display position change is being executed in step # 408 is made based on whether or not the copy conditions are stored in the memory areas 1 to 3 of the RAM 200.

Next, the case where the flag FMS is "1" in step # 400 (step # 400: YES) will be described. In this case, it is determined in step # 401 whether or not the copy magnification key 111 is pressed to cancel the copy magnification setting mode. If the copy magnification key 111 is not pressed (step # 401: NO), the process proceeds to step # 402 to continue the processing of the copy magnification setting mode. In step # 402, it is judged whether or not the copy magnification is set, and if it is set (step # 402: YE
In S), the contents set in step # 403 are stored in the RAM.
200 in memory. On the other hand, when the magnification key 111 is pressed (step # 401: YES), step # 4
At 04, the LED 111a is turned off and the flag FMS is set to "0".
Then, the standard screen is displayed on the display 100, and the magnification setting process ends. Here, when the magnification is set in step # 402 and the copy magnification of, for example, “× 1.224” is set, “copy magnification = ×” as shown in FIG.
The screen rewritten as “1.224” is displayed, and the magnification setting process ends.

Next, the setting of the magnification in step # 402 will be described with reference to FIGS. Step # 4
If it is determined that the display position change has not been performed in step 08 (step # 408: NO), the copy magnification setting screen (see FIG. 15) for which the display position change has not been performed is displayed on the display 100. To set the copy magnification,
This is a method of moving a cursor (hatched portion in the figure) to a desired magnification value by a rotation method. For example, when it is desired to set “× 1.224” as the copy magnification as shown by the shaded portion in FIG. 11, the selection key 103 corresponding to the display position of “enlargement” may be pressed twice.

On the other hand, if it is determined in step # 408 that the display position change is being executed (step # 408:
In (YES), the screen for setting the magnification after changing the display position (see FIG. 16) is displayed. In this case as well, FIG.
Similar to the case of 5, the copy magnification can be set according to the copy magnification setting screen after changing the display position. Here, as is clear from the description of the change mode in step # 3 described above, the information regarding the copy condition and the control code corresponding to this information correspond to the selection keys 101, 102, 103 in the RAM 20.
0 are stored in memory areas 1, 2, and 3. Then, the selection keys 101, 10 corresponding to the information display position
When 2, 103 are pressed, the control code stored in the area corresponding to each selection key is loaded. Therefore,
It is possible to copy under the copy condition set by the selection key.

In the above-described embodiment, an example in which the display position of only the information regarding the function setting, that is, the copy information of "actual size", "reduction", and "enlargement" is changed has been described. The display order of various magnification values in "enlargement" may be changed.

Further, in the present embodiment, the example in which the copying condition and the control code are stored in the memory areas 1 to 3 of the CPU 200 has been described, but the copying condition and the control program corresponding to this copying condition may be stored.

Further, although the selection keys 101, 102 and 103 are used to select the copying condition in this embodiment, the copying condition may be selected by the touch panel.

Furthermore, it goes without saying that the information relating to the function is not limited to the copying conditions such as the copying magnification described in the embodiment, but may be other functions. Furthermore, although an example in which the present invention is applied to a copying machine has been described, it can be widely applied not only to image forming apparatuses other than copying machines such as printers but also to OA equipment such as word processors and personal computers.

[0034]

As is apparent from the above description, according to the display device of the present invention, the display position designating means for designating a display position different from a predetermined display position with respect to the display position of the information related to the function setting. Since the display position changing means for displaying the information at the display position designated by the display position designating means is provided, the layout of the displayed information can be changed according to the usability of the user. The usability is very good for the user.
