2A and 2B are flowcharts showing numerical value change processing. FIG. 3 is a diagram showing an example of a setting screen. FIG. 4 is a diagram showing an example of a list image displayed on the setting screen. Hereinafter, the operation of the image forming apparatus 1 at the time of executing the numerical value change processing will be described with reference to FIGS. 2 to 4 and the like.

Hereinafter, it is assumed that the image forming apparatus 1 is in a state where the power is turned on. It is assumed that the user has input an instruction for selecting the copy function via the touch panel 16A. With reference to FIG. 3, when the control unit 10 receives the above instruction via the touch panel 16A, the display unit 15 causes the display unit 15 to display a setting screen 30 for setting a plurality of setting items related to the copy function.

The control unit 10 sets an input box 31 which is an area for displaying a numerical value indicating the number of copies to be set as a soft key on the display unit 15 and "1" for the numerical value displayed in the input box 31. A plus button 32 for adding and a minus button 33 for subtracting "1" from the numerical value displayed in the input box 31 are displayed on the setting screen 30. The input box 31, the plus button 32, and the minus button 33 are the central portion of the setting screen 30 in the longitudinal direction Y, and are provided at one end of the lateral direction X.

The control unit 10 causes the display unit 15 to display the list image 40 shown in FIG. 4 in the area 34. With reference to FIG. 4, the list image 40 includes a plurality of setting item keys 41A to 41O and the like arranged along the lateral direction X of the setting screen 30 as soft keys. When the control unit 10 receives a tap operation for any of the setting item keys 41A to 41O via the touch panel 16A, the control unit 10 sets a value for the setting item associated with the setting item key for which the tap operation has been performed. Is displayed on the display unit 15 as a screen for setting.

The control unit 10 cannot cause the display unit 15 to display the entire list image 40 in the area 34 at once. Therefore, the control unit 10 causes the display unit 11 to display only a part (hereinafter, referred to as “display portion”) 42 that can be displayed in the area 34 of the entire list image 40 in the area 34.

The control unit 10 displays on the display unit 15 a scroll bar 35 including a main body 35A extending along the lateral direction X and a knob 35B arranged on the main body 35A in the vicinity of the area 34. I'm letting you. The control unit 10 performs a slide operation in the lateral direction X with respect to the knob 35B or a tap operation with respect to an area of the main body 35A where the knob 35B is not arranged (hereinafter, referred to as a “main body portion”) via the touch panel 16A. Upon acceptance, the list image 40 is scrolled in the lateral direction X until the display unit 15 displays the display portion corresponding to the slide operation in the list image 40 or the tap operation on the main body portion. The area 34 and the scroll bar 35 are central portions in the longitudinal direction Y on the setting screen 30, and are provided from the central portion to the other end portion in the lateral direction X.

With reference to FIG. 2A, when the display unit 15 displays the setting screen 30, the control unit 10 starts executing the numerical value change process. In the numerical value change process, the control unit 10 waits until the slide operation is accepted via the touch panel 16A (NO in step S10).

(1) When the numerical value displayed in the input box 31 is the lower limit value FIG. 5 is a diagram showing an example of a setting screen when a slide operation is being performed. With reference to FIG. 5, the control unit 10 causes the display unit 15 to display the default numerical value “1” in the input box 31 in the predetermined first display color “black”. It is assumed that It is assumed that the user has performed a slide operation in the direction indicated by the arrow A1 starting from the input box 31 in order to set "700" as the number of copies.

When the control unit 10 determines that the slide operation is accepted via the touch panel 16A (YES in step S10), the control unit 10 determines whether or not the accepted slide operation originates from the input box 31 (step S11). .. In this case, since the first position of the slide operation detected by the touch panel 16A is located in the area of the input box 31, the control unit 10 determines that the slide operation originates from the input box 31 (step). YES in S11), it is determined whether or not the input box 31 is located at one end of the lateral direction X on the setting screen 30 (step S12).

On the other hand, for example, when the user performs a slide operation in the lateral direction X with respect to the knob 35B, the first position of the slide operation detected by the touch panel 16A is not located in the area of the input box 31. The control unit 10 determines that the slide operation does not start from the input box 31 (NO in step S11), and returns to the process of step S10. In this case, the control unit 10 executes a control program stored in the HDD 19 that is different from the numerical value change program, so that the display unit 15 displays a display corresponding to the slide operation on the knob 35B in the list image 40. The list image 40 is scrolled in the lateral direction X until the portion is displayed.

In step S12, the control unit 10 determines that the input box 31 is located at one end of the lateral direction X on the setting screen 30 (YES in step S12), and sets the input box 31 on the display unit 15. The input box 31 is moved to the other end side of the short direction X on the setting screen 30 until it is located at the center of the short direction X on the screen 30 (step S13). At this time, the control unit 10, together with the input box 31, displays all other GUIs (Graphical User Interfaces) displayed in the central portion of the longitudinal direction Y on the setting screen 30 in addition to the lateral direction X on the setting screen 30. Move to the edge side.

After moving the input box 31 and the like, the control unit 10 acquires a numerical change amount based on the slide distance and the change amount information stored in the HDD 17 (step S14). In this case, the control unit 10 calculates a slide distance of "10" inches based on the first and second positions of the slide operation, and corresponds to the calculated slide distance from the change amount information stored in the HDD 21. It is assumed that "400" is acquired as the amount of numerical change to be performed.

On the other hand, when the input box 31 is located at the center of the short direction X on the setting screen 30, the control unit 10 does not have the input box 31 located at one end of the short direction X on the setting screen 30. (NO in step S12), and the process proceeds to step S14 without moving the input box 31 or the like.

After acquiring the numerical value change amount, the control unit 10 determines whether or not the numerical value displayed in the input box 31 is the lower limit of the number of copies that can be set (step S15). Here, it is assumed that the lower limit value of the number of copies that can be set is "1" and the upper limit value is "999". The control unit 10 determines that the numerical value displayed in the input box 31 is the lower limit value (YES in step S15), and adds the acquired numerical value change amount to the numerical value displayed in the input box 31. The numerical value obtained by this (hereinafter, referred to as “increase value”) is calculated (step S16).

(1-1) When the increase value is smaller than the upper limit value In step S16, the control unit 10 adds the acquired numerical value change amount "400" to the numerical value "1" displayed in the input box 31. By adding, the increase value of "401" is calculated. After calculating the increase value, the control unit 10 determines whether or not the calculated increase value is equal to or greater than the upper limit value of the number of copies that can be set (step S17).

In this case, since the calculated increase value is smaller than the upper limit value "999", the control unit 10 determines that the increase value is not equal to or more than the upper limit value (NO in step S17), and displays the display unit 15. The calculated increase value is displayed in the input box 31 in the first display color (step S18). After displaying the increased value, the control unit 10 returns to the process of step S10.

(1-2) When the increase value is equal to or greater than the upper limit value On the other hand, for example, when the slide distance is "30" inches and the numerical change amount of "1200" is acquired by the control unit 10, the control unit 10 In step S16, the increase value of "1201" is calculated by adding the acquired numerical value change amount of "1200" to the numerical value of "1" displayed in the input box 31.

In this case, since the calculated increase value exceeds the upper limit value "999", the control unit 10 determines that the increase value is equal to or more than the upper limit value (YES in step S17), and displays the display unit 15. , The upper limit value is displayed in the input box 31 by the second display color "red" which is different from the first display color (step S19). After displaying the upper limit value, the control unit 10 returns to the process of step S10.

It is determined whether or not it is the upper limit of the number of copies (step S20). The control unit 10 determines that the numerical value displayed in the input box 31 is not the upper limit value (NO in step S20), and the first slide operation direction is toward one end of the lateral direction X on the setting screen 30. It is determined whether or not it is a direction (step S21).

In this case, since the second position of the slide operation is located on one end side of the lateral direction X on the setting screen 30 with respect to the center line L of the input box 31 extending along the longitudinal direction Y, the control unit 10 determines that the direction of the slide operation is the first direction (YES in step S21), and proceeds to the process of step S16.

In step S16, the control unit 10 calculates an increase value of "1201" by adding the acquired numerical value change amount of "800" to the numerical value of "401" displayed in the input box 31. ..

A numerical value (hereinafter, referred to as a “decrease value”) obtained by subtracting the acquired numerical value change amount from the numerical value displayed in the input box 31 is calculated (step S22).

(3-1) When the decrease value is not equal to or less than the lower limit value In step S22, the control unit 10 determines the amount of numerical change "200" obtained from the numerical value "999" displayed in the input box 31. By subtracting, a decrease value of "799" is calculated. After calculating the reduction value, the control unit 10 determines whether or not the calculated reduction value is equal to or less than the lower limit of the number of copies that can be set (step S23).

In this case, since the calculated decrease value is larger than the lower limit value "1", the control unit 10 determines that the decrease value is not equal to or less than the lower limit value (NO in step S23), and displays the display unit 15.

FIG. 8 shows a setting screen when the slide operation is being performed. It is a figure which shows another example. With reference to FIG. 8, it is assumed that the control unit 10 displays the numerical value "799" in the input box 31 in the first display color. It is assumed that the user has performed a slide operation in the direction indicated by the arrow A4 starting from the input box 31 in order to set "700" as the number of copies.

The control unit 10 determines that the slide operation is being accepted via the touch panel 16A (YES in step S10), and since the first position of the slide operation is located within the area of the input box 31, the slide operation is performed. Determines that the input box 31 is the starting point (YES in step S11).

In this case, since the input box 31 is located at the center of the short direction X on the setting screen 30, the control unit 10 has the input box 31 located at one end of the short direction X on the setting screen 30. It is determined that this is not the case (NO in step S12), and the process proceeds to step S14.

In step S14, the control unit 10 calculates a slide distance of "2.5" inches based on the first and second positions of the slide operation, and is calculated from the change amount information stored in the HDD 21.

With reference to FIG. 9, it is assumed that the control unit 10 displays the numerical value "699" in the input box 31 in the first display color. It is assumed that the user has performed a touch operation on the plus button 32 in order to set "700" as the number of copies.

When the control unit 10 receives a touch operation on the plus button 32 via the touch panel 16A, the control unit 10 executes a control program stored in the HDD 19 different from the numerical value change program, so that the "control program 10" displayed in the input box 31 is displayed. "700", which is a value obtained by adding "1" to the numerical value "699", is calculated, and the displayed unit 15 displays the calculated value in the input box 31.

It is assumed that the user confirms the numerical value "700" displayed in the input box 31 and inputs an instruction for determining the number of copies to be copied via the touch panel 16A. When the control unit 10 receives the above instruction via the touch panel 16A, the control unit 10 receives the numerical value displayed in the input box 31 as the set value of the number of copies.

After setting the number of copies, it is assumed that the user places the document on the platen glass of the image reading unit 11 and presses the start key provided on the operation unit 15 in order to start copying. When the control unit 10 detects that the start key is pressed, the control unit 10 causes the image reading unit 11 to read the document placed on the platen glass and generate image data.
