Description

  The present invention relates to a display input device and an image forming apparatus including the same.

  2. Description of the Related Art Conventionally, a display device with a touch panel installed in an image forming apparatus such as a multifunction peripheral is known as a display input device, and is referred to as an operation panel, for example. Such an operation panel receives an operation for changing the setting values of various setting items related to the operation of the image forming apparatus (see, for example, Patent Document 1).

  Some setting items relating to the operation of the image forming apparatus require numerical input when changing the setting value. As an example, a numerical value input is required when changing the setting of the number of copies or the copy magnification. Therefore, in Patent Document 1, when accepting numerical input, a numeric keypad as a software key is displayed on the operation panel. Thereby, a desired numerical value can be input by operating the numeric keypad (software key).

JP 2011-198165 A

  On the operation panel that displays numeric keys (software keys) and accepts numeric input, for example, a tap operation (touch operation such as tapping with a finger) is performed on any of the numeric keys “0” to “9”. When done, the numerical value corresponding to the tapped numeric key is entered. However, in this configuration, when inputting a numerical value of two or more digits, it is necessary to perform a tap operation on the numerical key twice or more. Therefore, it is bothersome and inconvenient for the user.

  As another example, there is an operation panel that displays a numerical value increase / decrease key (software key) including a plus key and a minus key when a numerical value input is accepted. For example, when the tap operation is performed once on the plus key, the input numerical value is increased by “1”, and when the tap operation is performed once on the negative key, the input numerical value is decreased by “1”. However, with this configuration, the tap operation on the numerical value increase / decrease key must be performed many times until the input numerical value reaches a desired value. Furthermore, it takes time until the input numerical value becomes a desired value.

  The present invention has been made to solve the above-described problems, and provides a display input device capable of improving user convenience by reducing operations during numerical value input and an image forming apparatus including the same. The purpose is to do.

  In order to achieve the above object, a display input device of the present invention displays a numerical value input screen for accepting numerical input, and a display unit that displays an input numerical value that is an input numerical value in the numerical value input screen; A touch panel unit that is provided for the display unit and receives a touch operation on the screen of the display unit, and a control unit that detects the touch operation received by the touch panel unit based on an output of the touch panel unit. When the touch panel unit receives a predetermined region dividing operation as a touch operation for dividing the predetermined region in the numerical value input screen along the second direction orthogonal to the first direction, the control unit A line passing through the determined position in the second direction is defined as a first reference line, and an edge opposite to the first reference line in the predetermined region in the first direction is defined as a second reference line, from the first reference line to the second reference line. The ratio for calculating the input numerical value, which is the ratio between the distance to the line and the distance from the first reference line to the dividing line of the predetermined area divided by the area dividing operation, is calculated, and the maximum numerical input range on the numerical input screen is obtained. A numerical value obtained by multiplying the value or minimum value by the ratio for calculating the input numerical value is obtained as the input numerical value. Further, the display unit displays the input numerical value obtained by the control unit in the numerical value input screen.

  In the configuration of the present invention, the maximum value or the minimum value of the numerical value input range on the numerical value input screen is multiplied by the ratio for calculating the input numerical value (the ratio obtained based on the position of the dividing line of the predetermined area divided by the area dividing operation). The entered numeric value is used as the input numeric value, and the entered numeric value is displayed in the numeric entry screen. Therefore, the ratio of the distance from the first reference line to the dividing line of the predetermined area to the distance from the first reference line to the second reference line (the ratio for calculating the input numerical value) is the maximum value of the numerical value input range on the numerical value input screen. Alternatively, if the region dividing operation is performed so as to match the ratio of the desired value (numerical value to be input) to the minimum value, it is possible to input the desired value with only one operation. Thereby, since the operation at the time of numerical value input reduces, a user's convenience improves.

  In the present invention, since the number of operations when inputting numerical values is reduced, convenience for the user is improved.

The operation panel 8 is also provided with various hard keys 84 such as a start key, a stop key, a reset key, and a numeric keypad.

<Hardware configuration of MFP>
As shown in FIG. 3, the multifunction peripheral 100 includes a main control unit 110. The main control unit 110 includes a main CPU 111, an image processing unit 112, and a storage unit 113. The image processing unit 112 includes an ASIC dedicated to image processing, and performs image processing (enlargement / reduction, density conversion, data format conversion, etc.) on the image data. The storage unit 113 includes a ROM and a RAM, and stores a control program and data. The main control unit 110 controls the operation of each unit of the multifunction peripheral 100 based on the program and data stored in the storage unit 113.

  Specifically, the main control unit 110 is connected to the image reading unit 1 and the printing unit 2 (the paper feeding unit 3, the paper transport unit 4, the image forming unit 5, and the fixing unit 6). The main control unit 110 controls the reading operation of the image reading unit 1 and the printing operation of the printing unit 2.

  The main control unit 110 is connected to the panel control unit 120. The panel control unit 120 includes a CPU 121 and a storage unit 122, receives instructions from the main control unit 110, controls the display operation of the operation panel 8, and detects operations performed on the operation panel 8. For example, the panel control unit 120 displays a button (software key) on the display unit 82, and when a touch operation is performed on the button, the panel control unit 120 detects the button that has received the touch operation based on the output of the touch panel unit 83. In addition, when a pressing operation for pressing the hard key 84 is performed, the panel control unit 120 detects the hard key 84 that has received the pressing operation based on an output of a switch that is turned on and off by pressing the hard key 84.

  The main control unit 110 is connected to the communication unit 130. Communication unit 130 is communicably connected to an external device (computer 200 or facsimile 300). The communication unit 130 receives an instruction from the main control unit 110 and transmits / receives image data and the like to / from an external device.

<Numerical input on the numeric input screen>
(Numerical input using the numerical value increase / decrease buttons)
The operation panel 8 accepts numerical input from the user as necessary. For example, when setting the copy magnification to any magnification (magnification other than the standard magnification), or when setting the document reading size to any size (size other than the standard size), enter a numerical value for the copy magnification or document reading size. There is a need. Further, when setting the maximum number of stored image data transmitted from an external device, it is necessary to input a numerical value for the maximum number of stored data. Also, when setting an identification number to be assigned to a destination registered in the address book, it is necessary to enter a numerical value for the identification number. Further, when the power saving mode (sleep mode) is installed in the multifunction peripheral 100, it is necessary to input a numerical value when setting the time until the power saving mode is activated. It should be noted that the setting items that require numerical input described above are examples, and there are many other setting items that require numerical input.

  When accepting numerical input, the panel control unit 120 causes the display unit 82 to display a numerical input screen 90 as shown in FIG. The panel control unit 120 causes the touch panel unit 83 to accept numerical input. Note that the numerical value input screen 90 shown in FIG. 4 is an example, and the layout of the screen can be changed.

  The numerical value input screen 90 includes a numerical value display area 91 for displaying numerical values input by the user (hereinafter referred to as input numerical values). The numerical value display area 91 has a substantially rectangular shape that is long in the left-right direction when viewed from the front side of the apparatus. The numerical display area 91 corresponds to the “predetermined area” of the present invention. The longitudinal direction (left-right direction) of the numerical display area 91 corresponds to the “first direction” of the present invention, and the short direction, which is the direction orthogonal to the longitudinal direction of the numerical display area 91, is “the second direction” of the present invention. Is equivalent to. In the following description, the longitudinal direction (first direction) of the numerical display area 91 is referred to as the X direction, and the short direction (second direction) of the numerical display area 91 is referred to as the Y direction.

  The numerical value input screen 90 is provided with a numerical value increase / decrease button NB including a plus button B1 and a minus button B2. Then, the panel control unit 120 detects a tap operation (touch operation such as hitting with a finger) on the numerical value increase / decrease button NB based on the output of the touch panel unit 83.

  When the tap operation is performed once on the plus button B1, the panel control unit 120 displays a numerical value obtained by adding “1” to the currently displayed input numerical value on the display unit 82 as a new input numerical value. When the tap operation is performed once for B2, a numerical value obtained by subtracting “1” from the currently displayed input numerical value is displayed on the display unit 82 as a new input numerical value.

(Numerical input without using numerical value increase / decrease buttons)
The panel control unit 120 detects whether or not an area division operation has been performed on the touch panel unit 83 when the display unit 82 displays the numerical value input screen 90. Note that the area dividing operation is predetermined as a touch operation for dividing the numerical display area 91 along the Y direction. For example, as shown in FIG. 5, the touch panel unit 83 uses a touch operation (an operation called a slide operation) to slide the touch position so as to divide the numerical display area 91 along the Y direction as an area division operation. Accept. When the panel control unit 120 detects an area division operation on the touch panel unit 83, the panel control unit 120 obtains a division ratio of the numerical display area 91 divided by the area division operation.

  At this time, the panel control unit 120 identifies the dividing line DL of the numerical value display area 91 divided by the area dividing operation, as shown in FIG. This dividing line DL is a line along the Y direction, which is substantially coincident with the sliding direction of the touch position at the time of the area dividing operation. Note that, as shown in FIG. 7, the sliding direction of the touch position during the region dividing operation (the direction of the white arrow in FIG. 7) may be shifted from the Y direction. For this reason, for example, the panel control unit 120 presets an intermediate line ML extending in the X direction between the upper and lower sides of the numerical value display area 91, and the line and the intermediate line along the slide direction of the touch position at the time of the area division operation. A line passing through the intersection with the line ML in the Y direction is identified as a dividing line DL. Or it is good also considering the line which passes along the intersection of the line along the slide direction of the touch position at the time of area | region division | segmentation operation, and the upper side or lower side of the numerical value display area 91 as a division line DL.

  Returning to FIG. 6, when the panel control unit 120 obtains the division ratio of the numerical value display area 91, a line passing through a predetermined position of the numerical value display area 91 in the Y direction (a line extending along the Y direction). The first reference line L1 is set, and the end side (side extending in the Y direction) facing the first reference line L1 of the numerical value display area 91 in the X direction is set as the second reference line L2. At this time, if the numerical value input range on the numerical value input screen 90 does not extend from the positive value to the negative value, the panel control unit 120 causes both ends of the numerical value display area 91 facing both the X direction (both ends extending along the Y direction). (Side), one side (right side) end side is defined as a first reference line L1, and the other side (left side) end side is defined as a second reference line L2. And the panel control part 120 calculates | requires the ratio of the distance D1 from the 1st reference line L1 to the 2nd reference line L2 and the distance D2 from the 1st reference line L1 to the dividing line DL as a division | segmentation ratio of the numerical display area 91. FIG. . The division ratio of the numerical value display area 91 obtained here corresponds to the “ratio for calculating an input numerical value” of the present invention, and will be referred to as an input numerical value calculating ratio in the following description.

  When determining the ratio for calculating the input numerical value, the panel control unit 120 calculates the input numerical value based on the ratio for calculating the input numerical value. Specifically, the panel control unit 120 obtains a numerical value obtained by multiplying the maximum value or the minimum value of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value as the input numerical value. Then, the panel control unit 120 causes the display unit 82 to display the obtained input numerical value.

  Here, when the numerical value in the input range on the numerical value input screen 90 is only a positive value, the panel control unit 120 obtains a numerical value obtained by multiplying the maximum value in the numerical value input range by the ratio for calculating the input numerical value as the input numerical value. As an example, as shown in FIG. 8, in the numerical value input screen 90 having a numerical value input range of “1” to “100”, the region division operation is performed so that the ratio of the distance D2 to the distance D1 is 0.62. Suppose. In this case, since the maximum value of the numerical value input range is “100”, the input numerical value obtained by the panel control unit 120 is “62 (= 100 × 0.62)”. As a result, the display unit 82 displays “62” as the input numerical value.

  When the numerical value in the input range on the numerical value input screen 90 is only a negative value, the panel control unit 120 obtains a numerical value obtained by multiplying the minimum value in the numerical value input range by the ratio for calculating the input numerical value as the input numerical value. As an example, although not shown, the region division operation is performed so that the ratio of the distance D2 to the distance D1 is “0.62” on the numerical value input screen 90 in which the numerical value input range is “−1” to “−100”. Suppose that In this case, since the minimum value of the numerical value input range is “−100”, the input numerical value obtained by the panel control unit 120 is “−62 (= −100 × 0.62)”. When the numerical value within the input range on the numerical value input screen 90 is only a negative value, one side (both sides extending along the Y direction) of the numerical value display area 91 facing the X direction (one side) The edge on the right side may be the second reference line L2, and the edge on the other side (the left side) may be the first reference line L1 (when the numerical value in the numerical value input range on the numerical value input screen 90 is only a positive value) It may be reversed for this).

  Further, in some cases, the numerical value input range on the numerical value input screen 90 may extend from a positive value to a negative value. In this case, the panel control unit 120 sets the first reference line L1 as a line passing in the Y direction through the position between both ends facing the X direction of the numerical display area 91. Then, the panel control unit 120 determines the edge on one side of the numerical display area 91 when the area dividing operation is performed on one side in the first direction with respect to the first reference line L1 in the numerical display area 91. A ratio for calculating the input numerical value is obtained as the second reference line L2, and a numerical value obtained by multiplying the maximum positive value in the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value is obtained as the input numerical value. On the other hand, if the area division operation is performed on the other side opposite to one side of the numerical display area 91, the panel control unit 120 sets the other side edge of the numerical display area 91 to the second reference line L2. Then, the ratio for calculating the input numerical value is obtained, and a numerical value obtained by multiplying the minimum negative value of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value is obtained as the input numerical value.

  As an example, it is assumed that the numerical value input range on the numerical value input screen 90 is “−50” to “50” as shown in FIG. In this case, for example, the panel control unit 120 sets, as the first reference line L1, a line that passes in the Y direction through an intermediate position between both ends facing the X direction of the numerical display area 91. When the area dividing operation is performed on one side (left side) with respect to the first reference line L1 in the numerical display area 91, the panel control unit 120 sets the second side edge of the numerical display area 91 to the second side. A ratio for calculating the input numerical value is obtained as the reference line L2, and a numerical value obtained by multiplying the maximum positive value “50” of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value is obtained as the input numerical value. On the other hand, when the area division operation is performed on the other side (right side) with respect to the first reference line L1 in the numerical display area 91, the panel control unit 120 sets the other side edge of the numerical display area 91 to the first side. The ratio for calculating the input numerical value is obtained as the two reference lines L2, and a numerical value obtained by multiplying the minimum negative value “−50” of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value is obtained as the input numerical value.

  By the way, for example, on the numerical value input screen 90 (see FIGS. 4 to 8) in which the numerical value input range is “1” to “100”, the touch is performed along the edge that is the second reference line L2 of the numerical value display area 91. When the touch operation for sliding the position is performed as the area dividing operation, the second reference line L2 and the dividing line DL overlap each other. That is, the ratio for calculating the input numerical value, which is the ratio between the distance D1 and the distance D2, is “1”. Therefore, the maximum value “100 (= 100 × 1)” can be input by sliding the touch position along the edge that is the second reference line L <b> 2 of the numerical display area 91.

  In the numerical value input screen 90 having a numerical value input range of “1” to “100”, the touch operation for sliding the touch position along the edge that is the first reference line L1 of the numerical value display region 91 is divided into regions. As a result, the first reference line L1 and the dividing line DL overlap, and the input numerical value obtained by the panel control unit 120 is a numerical value “0” outside the numerical value input range. In such a case, the panel control unit 120 does not display the obtained input numerical value on the display unit 82. In this case, it may be notified that a numerical value cannot be input, or may be notified that re-operation is urged.

(Scale display)
The panel control unit 120 causes the display unit 82 to display a scale 92 (see FIGS. 4 to 9) that serves as an indication of what numerical values are input when an area dividing operation is performed on the touch panel unit 83. . For example, the scale 92 is arranged on the lower side of the upper and lower sides of the numerical value display area 91. Alternatively, although not shown, a scale 92 may be arranged on the upper side of the upper and lower sides of the numerical value display area 91.

  When displaying the scale 92, the display unit 82 divides the numerical value display area 91 at a predetermined delimiter position. Then, the display unit 82 displays, as a scale 92, a numerical value that is an input numerical value when an area dividing operation is performed to divide the numerical value display area 91 along a line passing through the separation position in the Y direction.

  For example, when the numerical value input range on the numerical value input screen 90 is “1” to “100”, there is no particular limitation. However, as shown in FIGS. 4 to 8, five numerical value display areas 91 are equally spaced. (Separate positions are 4 places). In this case, the numerical values as the scales 92 attached to the four delimiter positions are “80”, “60”, “40”, and “20” in order from the delimiter position on one side (left side). . A numerical value “0” is assigned as the scale 92 to the position of the edge of the numerical display area 91 that is the first reference line L1, and the scale is positioned at the position of the edge of the numerical display area 91 that is the second reference line L2. A numerical value “100” may be attached as 92.

  Here, when the numerical value input range extends from a positive value to a negative value (when the line passing in the Y direction through the position between the opposite ends of the numerical value display area 91 in the X direction is the first reference line L1), From the user's point of view, it is not clear which position should be used as the reference for the region division operation. Therefore, in this case, as shown in FIG. 9, the delimiter position is set at least at the position of the first reference line L1 (the position where the input numerical value becomes “0” when the area dividing operation is performed), and the delimiter is set. The position is preferably given a numerical value “0” as a scale 92. In FIG. 9, as an example, in addition to the position of the first reference line L1, a scale where the position where the input numerical value becomes “25” and the position where “−25” becomes “−25” when the region dividing operation is performed is set as the separation position. 92 is illustrated.

(Fine adjustment of input value)
The panel control unit 120 detects a region dividing operation on the touch panel unit 83 and displays an input numerical value obtained in response to the region dividing operation on the display unit 82, and then a predetermined time (for example, several seconds to several tens of seconds) has elapsed. The touch panel unit 83 is allowed to accept a numerical value increase / decrease operation that is predetermined as a touch operation for increasing / decreasing (fine adjustment) the currently displayed input numerical value. For example, the touch panel unit 83 accepts the area division operation received again until a predetermined time has elapsed after accepting the area division operation as a numerical value increase / decrease operation.

  When the panel control unit 120 causes the touch panel unit 83 to accept a numerical value increase / decrease operation until a predetermined time elapses, as shown in FIG. A line passing through the position in the Y direction (a line extending along the Y direction) is set as the third reference line L3. For example, when accepting a numerical value increasing / decreasing operation, a line passing in the Y direction through an intermediate position between both ends corresponding to the X direction of the numerical value display area 91 is set as the third reference line L3.

  At this time, when the touch panel unit 83 accepts a numerical value increase / decrease operation (when the touch panel unit 83 accepts an area dividing operation again before a predetermined time elapses), the panel control unit 120 displays the numerical value display area 91 divided by the numerical value increasing / decreasing operation. The dividing line DL is identified. Hereinafter, the dividing line DL of the numerical value display area 91 divided by the numerical value increasing / decreasing operation is referred to as a dividing line DLA.

  When the numerical value increase / decrease operation is performed on one side in the X direction (here, the left side) with respect to the third reference line L <b> 3 in the numerical display area 91, the panel control unit 120 displays one of the numerical display areas 91. With the side edge as the fourth reference line L4, the distance D3 from the third reference line L3 to the fourth reference line L4 and the dividing line DLA of the numerical value display area 91 divided by the numerical value increasing / decreasing operation from the third reference line L3 The ratio with the distance D4 is obtained as the division ratio of the numerical value display area 91. The division ratio of the numerical value display area 91 obtained here corresponds to the “ratio for calculating the increase / decrease value” of the present invention, and is referred to as the ratio for calculating the increase / decrease value in the following description.

  Thereafter, the panel control unit 120 calculates the input numerical value after the increase / decrease based on the ratio for the increase / decrease value calculation. Specifically, the panel control unit 120 multiplies the predetermined increase / decrease value by the ratio for calculating the increase / decrease value, and increases the input numerical value currently displayed by the numerical value obtained thereby as the input numerical value after increase / decrease. Ask. The predetermined increase / decrease value is a predetermined numerical value, but can be changed according to the numerical value input range on the numerical value input screen 90 (for example, the larger the numerical value input range on the numerical value input screen 90 is, the larger the predetermined increase / decrease value is. May be increased).

  On the other hand, when the numerical value increasing / decreasing operation is performed on the other side (here, the right side) opposite to the one side in the X direction with respect to the third reference line L3 in the numerical display area 91, the panel control unit 120 The ratio for calculating the increase / decrease value is obtained using the other end of the numerical value display area 91 as the fourth reference line L4. After that, the panel control unit 120 obtains a numerical value obtained by reducing the input numerical value currently displayed by the numerical value obtained by multiplying the predetermined increase / decrease value by the ratio for calculating the increase / decrease value as the input value after increase / decrease.

  When the panel control unit 120 obtains the input value after the increase / decrease, the panel control unit 120 displays the input value after the increase / decrease on the display unit 82. That is, the display unit 82 newly displays the input numerical value after increase / decrease instead of the input numerical value currently displayed.

  For example, as shown in FIG. 11, it is assumed that “62” is currently being displayed as an input numerical value by the area division operation that has already been performed on the numerical value input screen 90 in which the predetermined increase / decrease value is set to “10”. Furthermore, it is assumed that the numerical value increasing / decreasing operation is performed on one side of the third reference line L3, and the ratio of the distance D4 to the distance D3 at that time is “0.3”. In this case, the ratio for calculating the increase / decrease value is “0.3”, and a value obtained by multiplying the predetermined increase / decrease value “10” by the ratio “0.3” for calculating the increase / decrease value is “3 (= 10 × 0.3)”. Therefore, the input numerical value after increase / decrease obtained by the panel control unit 120 is “65 (= 62 + 3)”. Therefore, the display unit 82 displays the input numerical value by switching from “62” to “65”.

  In addition, when the panel control unit 120 causes the touch panel unit 83 to accept a numerical value increase / decrease operation, an indication of how much the currently displayed input numerical value increases or decreases when the numerical value increase / decrease operation is performed on the touch panel unit 83. A scale 93 (see FIGS. 10 to 11) is displayed on the display unit 82. For example, the scale 93 is arranged on the lower side of the upper and lower sides of the numerical value display area 91. Alternatively, although not shown, a scale 93 may be arranged on the upper side of the upper and lower sides of the numerical value display area 91.

  When displaying the scale 93, the display unit 82 divides the numerical display area 91 at a predetermined delimiter position. Then, the display unit 82 indicates how much the input numerical value currently displayed increases or decreases when a numerical value increasing / decreasing operation is performed so as to divide the numerical value display area 91 along a line passing through the separation position in the Y direction. The indicated numerical value is displayed as a scale 93.

  It should be noted that the input numerical value can be finely adjusted by operating the numerical value increase / decrease button NB after the numerical value is input by the region dividing operation. Alternatively, the input numerical value can be finely adjusted by a numerical value increasing / decreasing operation, and then the input numerical value can be further finely adjusted by operating the numerical value increasing / decreasing button NB.

(Flow of control when accepting numeric input)
In the following, the flow of control when accepting numerical input on the numerical value input screen 90 will be described with reference to FIG. The start of the flowchart of FIG. 12 is when the panel control unit 120 causes the display unit 82 to display a screen.

  In step S <b> 1, the panel control unit 120 determines whether the screen displayed on the display unit 82 is the numerical value input screen 90. As a result, if the display screen is the numerical value input screen 90, the process proceeds to step S2, and if the display screen is not the numerical value input screen 90, the numerical input is not accepted. When the display screen is the numerical value input screen 90, the numerical value display area 91 in the screen is, for example, the minimum value of the numerical value input range, the maximum value of the numerical value input range, the default value, and the previously input value. Numeric values are displayed as input numeric values.

  When the process proceeds to step S <b> 2, the panel control unit 120 determines whether or not there is an area division operation on the touch panel unit 83. As a result, if the area dividing operation has been performed, the process proceeds to step S3.

  In step S3, the panel control unit 120 calculates an input numerical value based on the input numerical value calculation ratio. In step S4, the panel control unit 120 causes the display unit 82 to display an input numerical value based on the input numerical value calculation ratio.

  Subsequently, in step S5, the panel control unit 120 determines whether or not a predetermined time has elapsed since the input numerical value was displayed on the display unit 82. As a result, if the predetermined time has elapsed, the process proceeds to step S2, and if the predetermined time has not elapsed, the process proceeds to step S6. In step S <b> 6, the panel control unit 120 determines whether or not a numerical value increase / decrease operation is performed on the touch panel unit 83. As a result, if a numerical value increase / decrease operation has been performed, the process proceeds to step S7.

  In step S7, the panel control unit 120 calculates the input value after the increase / decrease based on the ratio for the increase / decrease value calculation. In step S8, the panel control unit 120 causes the display unit 82 to display the input numerical value after the increase / decrease based on the ratio for calculating the increase / decrease value. Thereafter, the process proceeds to step S5.

  In step S6, when the numerical value increase / decrease operation is not performed, the process proceeds to step S9. When the process proceeds to step S <b> 9, the panel control unit 120 determines whether or not a confirmation operation is performed on the touch panel unit 83. The confirming operation is an operation for confirming the currently displayed input numerical value. For example, the confirming operation is an operation of tapping the confirm button B (see FIGS. 4 to 11) arranged in the numerical value input screen 90. is there. As a result of determining whether or not the confirming operation is performed on the touch panel unit 83, the panel control unit 120 ends the acceptance of numerical input if the confirming operation is performed, and proceeds to step S5 if the confirming operation is not performed. .

  In step S2, if the region dividing operation is not performed, the process proceeds to step S10. In step S10, the panel control unit 120 determines whether an operation has been performed on the numerical value increase / decrease button NB. As a result, if an operation is performed on the numerical value increase / decrease button NB, the process proceeds to step S11.

  In step S11, the panel control unit 120 increases or decreases the input numerical value displayed on the display unit 82 based on the operation on the numerical value input button B. Then, the process proceeds to step S12. In step S10, the process proceeds to step S12 also when the operation for the numerical value increase / decrease button NB is not performed. When the process proceeds to step S <b> 12, the panel control unit 120 determines whether or not a confirmation operation is performed on the touch panel unit 83. As a result, if the confirming operation has been performed, acceptance of numerical input is terminated, and if the confirming operation has not been performed, the process proceeds to step S2.

  As described above, the operation panel 8 (display input device) of the multifunction peripheral 100 (image forming apparatus) according to the present embodiment displays the numerical value input screen 90 for accepting numerical input, and is the input numerical value. A display unit 82 that displays an input numerical value in the numerical value input screen 90, a touch panel unit 83 that is provided for the display unit 82 and receives a touch operation on the screen of the display unit 82, and a touch panel unit based on the output of the touch panel unit 83 A panel control unit 120 (control unit) that detects the received touch operation. Then, an area division operation predetermined as a touch operation for dividing the numerical value display area 91 (predetermined area) in the numerical value input screen 90 along the Y direction (second direction) orthogonal to the X direction (first direction) is performed. When the touch panel unit 83 accepts the panel control unit 120, a line passing through a predetermined position of the numerical display area 91 in the Y direction is set as the first reference line L 1, and the first reference line L 1 of the numerical display area 91 is set. Dividing the numerical display area 91 divided by the area dividing operation from the first reference line L1 and the distance D1 from the first reference line L1 to the second reference line L2 with the end side facing the X direction as the second reference line L2. A numerical value obtained by multiplying the maximum value or the minimum value of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value while obtaining a ratio for calculating the input numerical value that is a ratio with the distance D2 to the line DL. age Seek. The display unit 82 displays the input numerical value obtained by the panel control unit 120 in the numerical value input screen 90.

  In the configuration of the present embodiment, the ratio for calculating the input numerical value to the maximum value or the minimum value of the numerical value input range on the numerical value input screen 90 (obtained based on the position of the dividing line DL of the numerical value display area 91 divided by the area dividing operation). A numerical value obtained by multiplying the ratio is set as an input numerical value, and the input numerical value is displayed in the numerical value input screen 90. Accordingly, the ratio of the distance D2 from the first reference line L1 to the dividing line DL of the numerical value display area 91 with respect to the distance D1 from the first reference line L1 to the second reference line L2 (input numerical value calculation ratio) is a numerical value input screen. If the region division operation is performed so as to match the ratio of the desired value (the numerical value to be input) to the maximum value or the minimum value of the numerical value input range at 90, it becomes possible to input the desired value with only one operation. . Thereby, since the operation at the time of numerical value input reduces, a user's convenience improves.

  In the present embodiment, as described above, the touch panel unit 83 accepts a touch operation for sliding the touch position so as to divide the numerical display area 91 along the Y direction as an area division operation. With this configuration, the region dividing operation is intuitive and easy to understand.

  Note that a touch operation that slides the touch position so as to divide the numerical display area 91 along the Y direction may be an area division operation, but a touch operation that taps the numerical display area 91 only once may be an area division operation. Good. In this case, a line passing through the tap position in the area dividing operation in the Y direction may be used as the dividing line DL of the numerical value display area 91.

  In the present embodiment, as described above, the predetermined area for receiving the area dividing operation is the numerical display area 91. With this configuration, it is not necessary to separately secure a predetermined area for receiving the area dividing operation in the numerical value input screen 90. Thereby, the degree of freedom of the layout of the numerical value input screen 90 is increased. However, the area dividing operation may be received in an area other than the numerical value display area 91 in the numerical value input screen 90.

  In the present embodiment, as described above, the display unit 82 divides the numerical display area 91 at a predetermined separation position, and divides the numerical display area 91 along a line passing through the separation position in the Y direction. A numerical value that is an input numerical value when such an area dividing operation is performed is displayed as a scale 92. With this configuration, the area division operation can be performed using the scale 92 as a guideline, and thus the input numerical value does not become a value significantly different from the desired value.

  In the present embodiment, as described above, when the numerical value input range on the numerical value input screen 90 does not extend from a positive value to a negative value, the panel control unit 120 has both ends facing the X direction of the numerical value display area 91. An input numerical value is obtained by setting one end side of the sides as the first reference line L1 and the other end side opposite to the one side as the second reference line L2. As described above, if each of the one end side and the other end side in the X direction of the numerical display area 91 is the first reference line L1 and the second reference line L2, which of the numerical display area 91 is It becomes easy to understand whether or not the region division operation should be performed based on the position.

  In the present embodiment, as described above, when the numerical value input range on the numerical value input screen 90 extends from a positive value to a negative value, the panel control unit 120 determines whether the numerical value display area 91 is located between the opposite ends in the X direction. A line passing through a predetermined position in the Y direction is defined as a first reference line L1, and a region dividing operation is performed on one side in the X direction with respect to the first reference line L1 in the numerical display area 91. Is a ratio for calculating an input numerical value using the one side edge of the numerical value display area 91 as a second reference line L2, and a ratio for calculating the input numerical value to the maximum positive value of the numerical value input range on the numerical value input screen 90. The numerical value multiplied by is obtained as the input numerical value. On the other hand, when the area division operation is performed on the other side of the numerical display area 91 opposite to the one side, the panel control unit 120 sets the other side edge of the numerical display area 91 to the second reference line. A ratio for calculating the input numerical value is obtained as L2, and a numerical value obtained by multiplying the minimum negative value of the numerical value input range on the numerical value input screen 90 by the ratio for calculating the input numerical value is obtained as the input numerical value.

  With this configuration, even if the numerical value input range on the numerical value input screen 90 extends from a positive value to a negative value, the numerical value of either a positive value or a negative value can be changed by only one area division operation. It can be selectively input.

  Further, in the present embodiment, as described above, the touch panel unit 83 accepts the region dividing operation and the display unit 82 displays the input numerical value in the numerical value input screen 90 until the predetermined time elapses. When the area dividing operation is received again, the touch panel unit 83 receives the area dividing operation received again until a predetermined time elapses as a numerical value increasing / decreasing operation. Then, the panel control unit 120 sets a line passing through a predetermined position between both ends facing the X direction of the numerical display area 91 in the Y direction as the third reference line L3, and sets the third reference line L3 in the third numerical display area 91. When a numerical value increase / decrease operation is performed on one side in the X direction with respect to the reference line L3, the end on one side of the numerical value display area 91 is set as the fourth reference line L4 to the fourth reference line L3 to the fourth reference line. A ratio for calculating an increase / decrease value, which is a ratio between the distance D3 to the line L4 and the distance D4 to the dividing line DLA of the numerical value display area 91 divided by the numerical value increase / decrease operation from the third reference line L3, and a predetermined increase / decrease value A numerical value obtained by multiplying the input numerical value currently displayed by the numerical value obtained by multiplying by the ratio for calculating the increase / decrease value is obtained as the input numerical value after the increase / decrease. On the other hand, when the numerical value increasing / decreasing operation is performed on the other side opposite to one side of the numerical display area 91, the panel control unit 120 sets the other side edge of the numerical display area 91 to the fourth reference line. As L4, a ratio for calculating the increase / decrease value is obtained, and a numerical value obtained by decreasing the input numerical value currently displayed by the numerical value obtained by multiplying the predetermined increase / decrease value by the ratio for increasing / decreasing value is obtained as the input value after the increase / decrease. In addition, the display unit 82 newly displays the input value after the increase / decrease obtained by the panel control unit 120 instead of the currently displayed input value.

  According to this configuration, the input numerical value can be increased / decreased (finely adjusted) only by performing the region dividing operation (numerical value increasing / decreasing operation) again until a predetermined time elapses. That is, when finely adjusting the input numerical value, the operation of tapping the numerical value increase / decrease button NB to increase or decrease the input numerical value need not be performed many times.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the description of the above-described embodiment but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.
