Description

The present invention relates to an information processing device, and in particular to a technique for inputting setting values.

Technology is known for using soft keys, rather than hard keys, as input keys for inputting setting values. For example, Patent Document 1 discloses a technology in which a software keyboard is displayed on a touch panel display superimposed on another image in a transparent state indicating that no operation is being accepted, and when a touch operation on a switching section is detected, the software keyboard is displayed in an opaque state indicating that operation is being accepted.

JP 2020-3909 A

However, when inputting a setting value using a numeric keypad, if the order of the keys does not match the user's sense of increasing or decreasing a value, the user will be unable to intuitively input the setting value. Also, when changing the setting value using a sliding operation such as a flick on a touch panel, the user can intuitively increase or decrease the value, but if the setting value has a large number of digits, the number of flick operations required to input the setting value increases, which is time-consuming. The technology disclosed in Patent Document 1 simply switches the display state of a software keyboard and does not solve the above problems.

The present invention has been developed in consideration of the above circumstances, and aims to enable intuitive input of setting values and reduce the effort required by the user to input setting values.

An information processing device according to one aspect of the present invention includes a display unit, a touch panel overlaid on the display unit, and a control unit that executes a job according to a setting value set for a predetermined setting item. When the touch panel detects a plurality of input points spaced apart from one another, the control unit causes the display unit to display a numerical image indicating a predetermined numerical value at a position corresponding to each of the plurality of input points, and when the touch panel detects movement of any of the plurality of input points, the control unit changes the numerical image displayed at the position corresponding to the input point whose movement was detected to a numerical image indicating a numerical value different from the predetermined numerical value according to the direction of movement of the input point, and accepts the numerical value indicated by each of the plurality of numerical images as the numerical value of each digit constituting the setting value.

According to the present invention, a user can change the numerical values constituting a set value digit by digit by performing a simple operation such as, for example, moving multiple fingers on a touch panel in a desired direction. Therefore, compared to inputting a numerical value via a numeric keypad, the numerical value can be changed more intuitively. Also, compared to a case where the numerical value cannot be changed digit by digit, a set value with a large number of digits can be set with fewer operations, thereby reducing the effort required for the user to input a set value.

Below, an image forming apparatus as an information processing apparatus according to one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front cross-sectional view showing the structure of an image forming apparatus according to one embodiment of the present invention. FIG. 2 is a block diagram showing the internal configuration of the image forming apparatus. With reference to FIGS. 1 and 2, the image forming apparatus 1 is a multifunction machine equipped with multiple functions such as a copy function, a transmission function, a printer function, and a facsimile function. The housing of the image forming apparatus 1 contains multiple devices for realizing the various functions of the image forming apparatus 1. For example, the housing contains an image reading unit 11, an image forming unit 12, a fixing unit 13, a paper feed unit 14, etc.

The image forming device 1 includes a control unit 100. The control unit 100 includes a processor, a RAM (Random Access Memory), and a ROM (Read Only Memory). The processor is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or an ASIC (Application Specific Integrated Circuit).

The control unit 100 functions as the control unit 10 by the processor executing a control program stored in the ROM or HDD 18. The control unit 10 may be configured as a logic circuit, regardless of the operation based on the control program.

The control unit 10 is responsible for the overall control of the image forming apparatus 1. More specifically, the control unit 10 controls the operation of each unit of the image forming apparatus 1 and communication with a PC (Personal Computer) 23 and the like connected via a network. The control unit 10 also operates according to a display program described later, so that when the touch panel 16 detects a plurality of input points spaced apart from one another, the control unit 10 causes the display unit 15 to display numerical images indicating predetermined numerical values at positions corresponding to the plurality of input points, and when the touch panel 16 detects movement of the input point, the control unit 10 changes the numerical image displayed at the position corresponding to the input point whose movement has been detected to a numerical image indicating a different numerical value from the predetermined numerical value according to the direction of movement of the input point, and executes a numerical image display process to accept the numerical values indicated by each of the plurality of numerical images as the numerical values of each digit constituting the set value.

The image reading unit 11 reads the original by illuminating the original with a light irradiation unit and receiving the reflected light with a CCD (Charge-Coupled Device) sensor, thereby generating image data that represents the original image.

The image forming unit 12 includes a photosensitive drum, a charging device, an exposure device, a developing device, and a transfer device. The image forming unit 12 forms an image composed of a toner image on the recording paper P transported along the transport path T by the transport unit 17 based on the image data generated by the image reading unit 11 or image data input via the communication unit 22.

The fixing unit 13 heats and presses the recording paper P on which the toner image has been formed by the image forming unit 12, thereby fixing the toner image to the recording paper P.

The transport unit 17 includes a transport roller pair 17A, a discharge roller pair 17B, etc., and a transport motor electrically connected to the transport roller pair 17A and the discharge roller pair 17B, etc. The transport roller pair 17A and the discharge roller pair 17B, etc. are arranged along the transport path T. The control unit 10 drives the transport motor to rotate the transport roller pair 17A and the discharge roller pair 17B, etc., thereby transporting the recording paper P fed by the paper feed unit 14 along the transport path T toward the image forming unit 12 and the discharge tray 8.

The HDD 18 is a large-capacity storage device for storing various data such as image data generated by the image reading unit 11. The HDD 18 stores various control programs for implementing general operations of the image forming device 1. As one of the various control programs, the HDD 18 stores a display program for executing a numerical image display process according to one embodiment of the present invention.

The image processing unit 19 performs image processing as necessary on the image data generated by the image reading unit 11. The image memory 20 includes an area for temporarily storing the image data generated by the image reading unit 11.

Each part of the image forming device 1 is connected to a power source, and each part of the image forming device 1 operates when power is supplied from the power source.

[Operation of Image Forming Apparatus 1]
Figures 3A and 3B are flowcharts showing the numerical image display process. Figure 4 is a diagram showing an example of a setting screen. Figure 5 is a diagram showing an example of an item image. Figure 6 is a diagram showing an example of a display mode of an item image. Figures 7 to 9 are diagrams showing examples of numerical images. Hereinafter, the operation of the image forming device 1 when the numerical image display process is executed will be described with reference to Figures 3 to 9 etc. In the following description, it is assumed that the image forming device 1 is in a powered-on state.

It is assumed that the user of the image forming device 1 uses the touch panel 16 to input a selection instruction to select the copy function from among the multiple functions that the image forming device 1 can execute. When the control unit 10 receives the selection instruction via the touch panel 16, it causes the display unit 15 to display a setting screen 40 for setting values for each of the multiple setting items related to the copy function, as shown in FIG. 4. At this time, it is assumed that default setting values are set for each of the multiple setting items related to the copy function.

The user checks the setting screen 40 and touches the key 41. When the touch panel 16 detects a touch operation on the key 41 (hereinafter referred to as the "first touch operation"), the control unit 10 starts the numerical image display process shown in FIG. 3A and causes the display unit 15 to display an image (hereinafter referred to as the "item image") indicating a setting item whose setting value is composed of a numerical value, out of multiple setting items related to the copy function, in the longitudinal center of the setting screen 40, which is a predetermined first area (step S10).

In this case, as shown in FIG. 5, the control unit 10 causes the display unit 15 to display multiple item images, including item image 51 indicating the setting item "magnification" and item image 52 indicating the setting item "number of copies", in a row along the short side of the setting screen 40, in the center of the long side of the setting screen 40. At this time, the control unit 10 displays multiple item images all at the same size. Here, the setting value for the setting item "number of copies" can be set to a three-digit number up to "999". The setting value for the setting item "magnification" can be set to a three-digit number up to "400".

After the process of step S10, the control unit 10 repeats the process of determining that a second touch operation has not been detected (NO in step S11) and the process of determining that a further first touch operation has not been detected (NO in step S12) until it detects a touch operation on an item image (hereinafter referred to as a "second touch operation") or detects a further first touch operation on the key 41.

Here, it is assumed that the user has touched item image 52. When the touch panel 16 detects a touch operation on item image 52 (YES in step S11), the control unit 10 causes the display unit 15 to display the touched item image 52 in a display mode different from the other item images (step S13). In this case, as shown in FIG. 6, the control unit 10 causes the display unit 15 to display the item image 52 in a larger size than the other item images, and also displays a frame-shaped line image 61 surrounding the item image 52.

After the process of step S13, the control unit 10 repeats the process of determining that the input point has not been detected (NO in step S14) until the control unit 10 detects an input point in an area on the setting screen 40 where multiple items are not displayed (hereinafter referred to as the "second area"). Here, the input point refers to the part of the touch panel 16 that is touched by the user's finger.

Here, it is assumed that the user touches the second area at one longitudinal end of the setting screen 40 with the middle finger, ring finger, and little finger of the right hand. When the touch panel 16 detects input points in the second area (YES in step S14), the control unit 10 determines whether the number of input points spaced apart from each other is equal to or less than the maximum number of digits that can be input for the setting value of the setting item indicated by the item image 52 (step S15).

Here, the control unit 10 recognizes the order of the input points according to the order in which they are arranged from one end to the other end in the longitudinal direction of the setting screen 40. In this case, the control unit 10 recognizes the input point touched by the little finger as the first input point, the input point touched by the ring finger as the second input point, and the input point touched by the middle finger as the third input point.

Therefore, the number of input points is "3". In addition, since the maximum number of digits for the setting item "number of copies" is "3", the control unit 10 determines that the number of input points is equal to or less than the maximum number of digits (YES in step S15), and causes the display unit 15 to display a numerical image showing a predetermined numerical value from "0" to "9" at a position corresponding to each input point (step S16).

In this case, as shown in FIG. 7, the control unit 10 causes the display unit 15 to display a numerical image 71A indicating "1" at a position corresponding to the first input point, a numerical image 72A indicating "0" at a position corresponding to the second input point, and a numerical image 73A indicating "0" at a position corresponding to the third input point.

After the process of step S16, the control unit 10 repeats the process of determining that movement of the input point has not been detected (NO in step S17) and the process of determining that a further second touch operation has not been detected (NO in step S18) until it detects movement of the input point or detects a further second touch operation on the item image 52.

Here, it is assumed that the user slides his/her little finger from the first input point in a direction X1 toward one end of the short side of the setting screen 40. When the touch panel 16 detects the movement of the input point due to the above-mentioned sliding operation (YES in step S17), the control unit 10 changes the numerical image displayed at the position corresponding to the input point whose movement has been detected, according to the direction of movement of the input point (step S19).

Here, when the movement direction of the input point is direction X1, the control unit 10 changes the numerical image displayed at the position corresponding to the input point whose movement was detected to a numerical image showing a numerical value that is "1" less than the numerical value indicated at the time the movement was detected. When the movement direction of the input point is direction X2 toward the other end of the short side of the setting screen 40, the control unit 10 changes the numerical image corresponding to the input point whose movement was detected to a numerical image showing a numerical value that is "1" more than the numerical value indicated at the time the movement was detected.

In this case, as shown in FIG. 8, the control unit 10 changes the numerical image 71A indicating "1" displayed at the position corresponding to the first input point where the movement was detected to a numerical image 71B indicating "0." After processing step S19, the control unit 10 returns to processing step S17.

The user then performs an operation of sliding the ring finger from the second input point in the direction X2 twice. In this case, the control unit 10 executes the process of determining that movement of the input point has been detected (YES in step S17) and the process of step S19 twice, and changes the numerical image 72A indicating "0" displayed at the position corresponding to the moved second input point to a numerical image indicating "1", and further changes it to a numerical image 72B indicating "2".

The user then slides his/her middle finger once from the third input point in the direction X2. In this case, the control unit 10 executes the process of determining that movement of the input point has been detected (YES in step S17) and the process of step S19, and changes the numeric image 73A indicating "0" that is displayed at the position corresponding to the moved third input point to a numeric image 73B indicating "1."

The user checks numeric images 71B, 72B, and 73B and touches item image 52. When a further second touch operation on item image 52 is detected by touch panel 16 (YES in step S18), control unit 10 accepts the numerical values indicated by each numeric image as the numerical values of each digit constituting the setting value for the setting item indicated by item image 52, as shown in FIG. 3B (step S20).

In this case, the control unit 10 accepts the number indicated by numerical image 71B as the first digit of the set value, the number indicated by numerical image 72B as the second digit of the set value, and the number indicated by numerical image 73B as the third digit of the set value. Therefore, the control unit 10 accepts the number "120" as the set value for the setting item "Number of Copies" indicated by item image 52.

After processing in step S20, the control unit 10 causes the display unit 15 to display the received setting value in a predetermined third area of the setting screen 40 (step S21). In this case, the control unit 10 causes the display unit 15 to display the received setting value of "120" in the third area 42 for displaying the setting value for the setting item "number of copies."

After processing step S21, the control unit 10 causes the display unit 15 to end the display of all numerical images and to display the item image 52 in the original display mode (step S22). In this case, the control unit 10 causes the display unit 15 to end the display of numerical images 71B, 72B, and 73B, to display the item image 52 in the same size as the other item images, and to end the display of the line image 61. This returns the state of the setting screen 40 to the state shown in FIG. 5. After processing step S22, the control unit 10 returns to the processing of step S11.

The user checks the setting value displayed in the third area 42 and touches the key 41 again. When the control unit 10 detects a further first touch operation on the key 41 via the touch panel 16 (YES in step S12), it causes the display unit 15 to end the display of all item images (step S23). In this case, the control unit 10 causes the display unit 15 to end the display of all item images, including item images 51 and 52. This returns the state of the setting screen 40 to the state shown in FIG. 4. After the processing of step S23, the control unit 10 ends the numerical image display processing.

The user places an original on the platen glass 7 and touches the start key 44 on the setting screen 40. When the control unit 10 detects the touch operation on the key 44 via the touch panel 16, it causes the image reading unit 11 to read the original placed on the platen glass 7 and generate image data according to the setting values set for each of the multiple setting items related to the copy function, and then executes a copy job in which the image forming unit 12 etc. forms the original image indicated by the generated image data on recording paper P. As a result, 120 copies of the printed matter are output.

On the other hand, for example, if the user touches the second area at one longitudinal end of the setting screen 40 with the index finger, middle finger, ring finger, and little finger of the right hand, and the number of input points detected by the touch panel 16 is "4", the control unit 10 determines that the number of input points exceeds the maximum number of digits (NO in step S15), and selects adjacent input points of the maximum number of digits from the multiple detected input points (step S24).

In this case, as shown in FIG. 9, the control unit 10 selects the second to fourth input points from the first input point touched by the little finger, the second input point touched by the ring finger, the third input point touched by the middle finger, and the fourth input point touched by the index finger on the touch panel 16. After processing step S24, the control unit 10 proceeds to processing step S16.

In this case, in step S16, the control unit 10 causes the display unit 15 to display a numerical image 71A at a position corresponding to the second input point, a numerical image 72A at a position corresponding to the third input point, and a numerical image 73A at a position corresponding to the fourth input point. After processing in step S16, the control unit 10 executes the processing from step S17 onwards in the same manner as described above.

According to the above embodiment, when the first to third input points spaced apart are detected by the touch panel 16, the control unit 10 causes the display unit 15 to display numerical images 71A, 72A, and 73A at positions corresponding to the first to third input points, respectively, and when the touch panel 16 detects, for example, movement of the first input point in the direction X1, the control unit 10 changes the numerical image 71A displayed at the position corresponding to the first input point to numerical image 71B. The control unit 10 accepts the numerical values indicated by the numerical images 71B, 72B, and 73B as the numerical values of each digit constituting the setting value, and executes the copy job according to the accepted setting value.

This allows the user to change the numerical values constituting the set value digit by digit by performing a simple operation such as moving multiple fingers on the touch panel 16 in the desired direction of the X1 direction and the X2 direction. Therefore, the numerical values can be changed more intuitively than when inputting numerical values via the numeric keypad. Also, compared to when it is not possible to change numerical values digit by digit, a set value with a large number of digits can be set with fewer operations, thereby reducing the effort required by the user to input a set value.

Also, according to the above embodiment, when the number of input points is "4" and exceeds the maximum number of digits that can be input for the set value, which is "3", the control unit 10 selects the second to fourth input points from the first to fourth input points, which correspond to the maximum number of digits, and displays the numerical image 71A, the numerical image 72A, and the numerical image 73A at the positions corresponding to the selected second to fourth input points, respectively.

This allows users to input a setting value without making a mistake in the number of digits that can be input, even if they are not aware of the maximum number of digits, improving user convenience.

(First Modification)
In the above embodiment, when the number of input points is equal to or less than the maximum number of digits that can be input for the setting value, the control unit 10 causes the display unit 15 to display numerical images at positions corresponding to all of the detected input points, respectively, but the present invention is not limited to such an embodiment.

In a first variation of the above embodiment, when the number of input points is the same as the maximum number of digits, the control unit 10 displays a numerical image at a position corresponding to each of all detected input points, in the same manner as in the above embodiment. On the other hand, when the number of input points is less than the maximum number of digits, new input points are added so that the number of input points is the same as the maximum number of digits, and numerical images are displayed at positions corresponding to all detected input points and at a position corresponding to the new input point that has been added.

10 is a diagram showing an example of a numeric image displayed when the number of input points is less than the maximum number of digits. For example, as shown in FIG. 10, assume that the user touches the second area at one end of the longitudinal direction of the setting screen 40 with the middle finger and ring finger of the right hand. In this case, the touch panel 16 detects the first input point touched by the ring finger and the second input point touched by the middle finger, and the number of input points becomes "2". Therefore, the control unit 10 determines that the number of input points is less than the maximum number of digits, "3", and adds a new input point adjacent to the second input point so that the number of input points becomes "3". The control unit 10 then displays a numeric image 71A at a position corresponding to the first input point, a numeric image 72A at a position corresponding to the second input point, and a numeric image 73A at a position corresponding to the new input point.

This allows users to easily find out the maximum number of digits even if they are not aware of it, further improving user convenience.

In this case, the number of fingers touching the touch panel 16 does not match the number of displayed numerical images, but the control unit 10 executes the following process (i) or (ii) to change the numerical image 73A displayed at the position corresponding to the new input point. In process (i), when the touch panel 16 detects movement of the new input point, the control unit 10 changes the numerical image 73A to a numerical image showing another numerical value according to the movement direction of the new input point.

For example, suppose that the user touches a position corresponding to a new input point with the index finger of the right hand, and then slides the index finger in direction X2 a number of times or a distance sufficient to advance the numerical value "0" by "5". When the touch panel 16 detects the movement of the new input point in response to the above-mentioned sliding operation, the control unit 10 changes the numerical value image 73A indicating "0" to another numerical value image indicating the numerical value "5".

On the other hand, in the process of (ii), when the control unit 10 detects the movement of the second input point closest to the new input point by the touch panel 16, the control unit 10 changes at least one of the numerical image 72A displayed at the position corresponding to the second input point and the numerical image 73A displayed at the position corresponding to the new input point, depending on the direction of movement of the second input point.

For example, as shown in FIG. 10, when the combination of numeric image 72A and numeric image 73A indicates the numerical value "00", the user slides the middle finger of the right hand touching the second input point in direction X2 a number of times or a distance sufficient to advance the numerical value "00" by "15". When the touch panel 16 detects the movement of the second input point in response to the sliding operation, the control unit 10 changes numeric image 72A and numeric image 73A to a combination of two numeric images indicating the numerical value "15".

By performing process (ii), the user can change the numerical image 73A displayed at the position corresponding to the new input point using only the finger that originally touched the touch panel 16, thereby improving user convenience.

(Second Modification)
In addition, in the above embodiment, the user touched the second area at one end of the longitudinal direction of the setting screen 40 with the fingers of his/her right hand, but it is also envisioned that, for example, the user touches the second area at one end of the longitudinal direction of the setting screen 40 with the fingers of his/her left hand.

In a second variation of the above embodiment, when the control unit 10 detects an input point in the second area at one end of the length of the setting screen 40, it determines that the user is right-handed and executes the same process as in the above embodiment. On the other hand, when the control unit 10 detects an input point in the second area at the other end of the length of the setting screen 40, it determines that the user is left-handed and executes the same process as in the above embodiment, except that it recognizes the order of the input points according to the order from the other end of the length of the setting screen 40 to the one end.

FIG. 11 is a diagram showing another example of a numerical image according to the second modified example. For example,
It is assumed that the user touches the second region on the other longitudinal end side of the setting screen 40 with the middle finger, ring finger, and little finger of the left hand. In this case, the control unit 10 recognizes the order of the input points according to the arrangement order from the other longitudinal end side to one end side of the setting screen 40. That is, the control unit 10 recognizes the input point touched by the little finger as the first input point, the input point touched by the ring finger as the second input point, and the input point touched by the middle finger as the third input point.

The control unit 10 then causes the display unit 15 to display a numerical image 71A at a position corresponding to the first input point, a numerical image 72A at a position corresponding to the second input point, and a numerical image 73A at a position corresponding to the third input point. As a result, for example, the numerical images 71A, 72A, and 73A shown in FIG. 11 are displayed on the display unit 15 so as to be symmetrical with respect to the center line L1 extending along the short side at the center of the longitudinal direction of the setting screen 40 with respect to the numerical images 71A, 72A, and 73A shown in FIG. 7.

This allows the display position of the numerical image to change depending on the user's dominant hand, further improving user convenience.

(Other Modifications)
In the above embodiment, the control unit 10 changes the size of the touched item image 52 and displays it on the display unit 15 as a different display mode, and also displays the line image 61, but the present invention is not limited to such an embodiment. For example, the control unit 10 may display the touched item image 52 in a color different from other item images.

In the above embodiment, the control unit 10 changes the numeric image so that the numeric value increases or decreases by "1" with one slide operation, but the present invention is not limited to such an embodiment. For example, the control unit 10 may change the numeric image so that the numeric value increases or decreases by an amount corresponding to the speed or distance of the slide operation.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, in the above embodiment, the image forming device 1, which is a color multifunction device, is used as the information processing device, but this is merely one example, and other image forming devices such as a monochrome multifunction device, a copy machine, or a facsimile machine may also be used, or other devices such as a tablet terminal or a smartphone may also be used.

Furthermore, the configuration and processing of the above embodiment shown in Figures 1 to 11 are merely one embodiment of the present invention, and are not intended to limit the present invention to these configurations and processing.
