May end up. To solve this problem, for example, Japanese Patent Laid-Open No. 2003-196031 discloses a position on the panel surface of a touch panel that belongs to an input area that is adjacent to an input area that generates a desired input signal. An erroneous input detecting means for detecting that the input operation position is erroneously detected, and when the erroneous input detection means detects an erroneous input at the input operation position, the input operation position is close to or adjacent to an input area for generating a desired input signal adjacent thereto. As described above, there is described a touch panel input device comprising correction means for correcting both input areas on the panel surface.

However, since the touch panel input device described in Japanese Patent Application Laid-Open No. 2003-196031 must detect an erroneous input, there is a problem that it cannot cope with a case where it is difficult to detect an erroneous input by a user. For example, when there is no space for displaying all of a plurality of objects on the screen, a part of the plurality of objects may be displayed at different times, so-called scroll display. The object displayed on the screen is changed in response to the detection of the position in the scroll button on the touch panel. When the object is arranged in the vicinity of the scroll button, a touch on the scroll button by the user may be detected as a touch on the object. When a touch on the scroll button by the user is detected as a touch on the object, it is difficult to determine that the touch on the object by the user is an erroneous input.

Accordingly, among the second to (N + 1) th selected images, N selected images including the first selected image whose order is earlier than the second-most selected image, for example, The first to Nth selected images are selected and arranged side by side in the scroll area.

  The instruction acceptance image display unit 61 displays a scroll instruction acceptance image for accepting a scroll instruction in the vicinity of the scroll area. Since the scroll instruction includes a scroll instruction indicating a feed instruction and a scroll instruction indicating a return instruction, the instruction reception image display unit 61 includes a scroll instruction reception image indicating a feed instruction and a scroll instruction reception image indicating a return instruction. Are displayed on the LCD 165. When displaying the scroll instruction acceptance image on LCD 165, instruction acceptance image display section 61 outputs the position of the scroll instruction acceptance image on the display surface of LCD 165 to mode switching section 51 and instruction detection section 53.

  The mode switching unit 51 switches the reception mode between the normal mode and the enlargement mode based on the position on the display surface of the LCD 165 detected by the touch panel 169 and outputs the reception mode to the instruction detection unit 53. The mode switching unit 51 receives the position of the scroll instruction acceptance image on the display surface of the LCD 165 from the instruction acceptance image display unit 61. Touch panel 169 detects the position instructed by the user when the user indicates the display surface of LCD 165.

  The mode switching unit 51 switches the reception mode to the normal mode when the operation screen is displayed. Further, after the operation screen is displayed, the mode switching unit 51 accepts when the touch panel 169 continuously detects the position in the scroll instruction acceptance image or the position in the extension area around the scroll instruction acceptance image for a predetermined number of times or more. Switch the mode from normal mode to enlarged mode. The extension area is an area around the scroll instruction acceptance image and is not limited, but is an area within a predetermined distance range from the scroll instruction acceptance image, for example. Since the scroll instruction acceptance image is arranged in the vicinity of the scroll area, at least a part of the extension area may overlap with a part of the selected image.

  The mode switching unit 51 switches the reception mode from the expansion mode when the touch panel 169 does not continuously detect the position in the scroll instruction reception image or the position in the expansion area after switching the reception mode to the expansion mode. Switch to normal mode.

  The mode switching unit 51 receives a threshold value from the threshold value determining unit 55. The mode switching unit 51 causes the touch panel 169 to scroll before the elapsed time after the touch panel 169 detects the position in the scroll instruction acceptance image or the position in the extension area around the scroll instruction acceptance image reaches the threshold value. When the position in the instruction reception image or the position in the extension area around the scroll instruction reception image is detected, the position in the scroll instruction reception image or the position in the extension area around the scroll instruction reception image is detected continuously. Judgment is made and the reception mode is switched to the enlargement mode. After switching the reception mode to the enlargement mode, the mode switching unit 51 detects the position in the scroll instruction acceptance image or the extension after the touch panel 169 has finally detected the position in the scroll instruction acceptance image or the position in the extension area. When the elapsed time without detecting the position in the region becomes equal to or greater than the threshold value, the reception mode is switched to the normal mode.

  The threshold value determination unit 55 determines a threshold value. For each user who operates MFP 100, an interval for continuously indicating the position in the scroll instruction reception image or the position in the extended area around the scroll instruction reception image is stored. A threshold is determined based on the determined interval. For example, the maximum value of the stored interval is determined as the threshold value. As a method for determining the threshold, in addition to the maximum value, an average value may be used, an intermediate value may be used, or a minimum value may be used. Moreover, the threshold value determination part 55 is good also as predetermined time. For example, it may be a time for the user to confirm the number N of selectable images displayed in the scroll area.

  The instruction detection unit 53 receives the position of the scroll instruction reception image on the display surface of the LCD 165 from the instruction reception image display unit 61, and the selection image identification information of each of the selectable number N of selected images from the selection image display unit 63 and the LCD 165. The position on the display surface is input, and the acceptance mode is input from the mode switching unit 51. When the reception mode is the normal mode, when the touch panel 169 detects any internal position of the selectable number N of selection images, the instruction detection unit 53 selects the selection image that includes the detected position. An instruction operation is detected. When detecting the selected image instruction operation, the instruction detecting unit 53 outputs the selection instruction to the selected image display unit 63 and the state switching unit 65. The selection instruction includes selected image identification information of a selected image including a position detected by the touch panel 169.

  When the acceptance mode is the normal mode, when the position inside the scroll instruction image is detected by the touch panel 169, the instruction detection unit 53 detects a scroll operation that instructs the scroll instruction image including the detected position. The instruction detection unit 53 outputs a scroll instruction to the selected image display unit 63 when detecting a scroll operation. The scroll instruction includes a feed instruction and a return instruction. When the position in the scroll instruction reception image corresponding to the feed instruction is detected, the instruction detection unit 53 outputs a scroll instruction indicating the feed instruction to the selection image display unit 63, and the scroll instruction reception image corresponding to the return instruction. When the position is detected, a scroll instruction indicating a return instruction is output to the selected image display unit 63.

  When the reception mode is the expansion mode, the instruction detection unit 53 detects the scroll operation when the position inside the scroll instruction image is detected by the touch panel 169 as in the case where the reception mode is the normal mode. In addition, when the reception mode is the expansion mode, the instruction detection unit 53 detects a scroll operation when the position inside the expansion area corresponding to the scroll instruction image is detected by the touch panel 169, as in the case where the reception mode is the normal mode. Is detected.

  The extended area may overlap with a part of the selected image. When the acceptance mode is the expansion mode, the instruction detection unit 53 selects the selected image indicating operation that instructs the selected image including the detected position when the touch panel 169 detects the position within the expanded area and the selected image. Without detecting this, a scroll operation that indicates a scroll instruction image corresponding to the extended region including the detected position is detected. The scroll instruction acceptance image corresponding to the extension area is a scroll instruction acceptance image arranged inside the extension area. When the reception mode is the expansion mode, the instruction detection unit 53 performs a selection image instruction operation for instructing a selection image including the detected position when a position other than the expansion area within the selection image is detected by the touch panel 169. To detect.

  In response to the selection instruction input from the instruction detection unit 53, the state switching unit 65 switches the state of the selected image specified by the selected image identification information included in the selection instruction. For example, the display mode of the selected image is different from other selected images. Specifically, the state switching unit 65 makes the selected image specified by the selected image identification information included in the selection instruction higher in brightness than the other selected images, and displays the other selected images for normal display. To highlight it. In addition, when the selected image is associated with a command for displaying another window, the state switching unit 65 executes the command and displays a window related to the selected image.

  The state switching unit 65 changes the state of the selected image based on the state of the selected image specified by the selected image identification information included in the selection instruction in response to the selection instruction input from the instruction detecting unit 53 after switching the state of the selected image. Return to. When the display mode is different from other selected images, the same display mode as that of the other selected images is set. When another window is displayed, the display of the other window is stopped. For this reason, after the operation screen is displayed, the mode switching unit 51 uses the touch panel 169 as a condition for switching the reception mode from the normal mode to the enlargement mode in the position in the scroll instruction reception image or around the scroll instruction reception image. It is preferable that the number of times the positions in the extended region are continuously detected be an even number. As a result, when the reception mode is switched to the enlargement mode, the state of the selected image can be prevented from being switched.

  FIG. 5 is a diagram illustrating an example of the operation screen. Here, a case where the operation screen is a screen displaying an address book will be described as an example. Further, a case where the address book includes data of 10 destinations will be described as an example. Referring to FIG. 5, operation screen 500 includes a scroll area 510. The scroll area has a size that allows four of the ten selected images respectively corresponding to the ten destination data to be displayed vertically. In the operation screen 500, five selection images 525 to 528 corresponding to the fifth to eighth destination data in order are arranged in the scroll area 510 side by side in the vertical direction. The operation screen 500 also includes a scroll instruction acceptance image 531 indicating a return instruction on the right side of the fourth selection image 525 displayed at the upper end of the scroll area 510. An area within a predetermined range from the scroll instruction acceptance image 531 indicating a return instruction is an extended area 531A. A part of the overlapping area 531B of the extended area 531A overlaps part of the selected image 525. Further, the operation screen 500 includes a scroll instruction reception image 533 indicating a sending instruction on the right side of the eighth selection image 528 displayed at the lower end of the scroll area 510. An area within a predetermined range from the scroll instruction reception image 533 indicating a feed instruction is an extended area 533A. A part of the overlapping region 533B of the extension region 533A overlaps with a part of the selected image 528.

  If the user indicates a scroll instruction acceptance image 531, a scroll operation indicating a return instruction is detected, and the third to seventh selection images are displayed in the scroll area 510. If the user indicates the scroll instruction acceptance image 533, a scroll operation indicating a feed instruction is detected, and the fifth to ninth selection images are displayed in the scroll area 510.

  In addition, when the user continuously indicates the expansion area 531A of the scroll instruction reception image 531, the reception mode is switched to the enlargement mode. For example, if the user indicates the extended area 531A of the scroll instruction reception image 531 twice in succession, a scroll operation indicating a return instruction is detected, and the third to seventh selection images are displayed in the scroll area 510. Is done. When the user designates the extended area 531A of the scroll instruction acceptance image 531 once, since the acceptance mode is the normal mode, the scroll operation is not accepted. However, when the user designates twice continuously, the acceptance mode is changed to the enlargement mode. In addition to switching, a scroll operation is accepted.

  In addition, if the user points twice continuously in the overlapping area 513B in the extended area 531A of the scroll instruction reception image 531, a scroll operation indicating a return instruction is detected, and the third to seventh positions are detected in the scroll area 510. The selected image is displayed. In this case, when the user designates the overlapping area 531B of the expansion area 531A of the scroll instruction acceptance image 531 once, the acceptance mode is the normal mode, so the scroll operation is not accepted and the selection image instruction operation for selecting the selection image 525 is selected. Is accepted. In this case, the display mode of the selected image 525 is highlighted and the user is notified that the selected image 525 has been selected. Thereafter, when the user designates the overlapping area 531B of the expansion area 531A of the scroll instruction acceptance image 531 twice, the selection image instruction operation is accepted, and the acceptance mode is switched to the enlargement mode and the scroll operation is accepted. In this case, the display mode of the selected image 525 is reversed and the normal display is restored, and the user is notified that the selected image 525 is not selected.

  Furthermore, after the acceptance mode is switched to the enlargement mode, when the elapsed time since the scroll instruction acceptance image 531 or the expanded area 531A is last designated by the user exceeds a threshold value, the acceptance mode is switched to the normal mode. It is done.

  FIG. 6 is a flowchart illustrating an example of the flow of the operation reception process. The operation reception process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes an operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. Referring to FIG. 6, CPU 111 displays a menu screen on LCD 165 (step S01). For example, the menu screen is an operation screen defined by default. The menu screen includes a plurality of pieces of screen identification information for identifying a plurality of operation screens.

  In the next step S02, it is determined whether or not an operation screen has been selected. When the touch panel 169 detects an operation instructing any one of a plurality of pieces of screen identification information included in the menu screen while the menu screen is displayed on the LCD 165, it is determined that the operation screen has been selected by the user. Further, the operation screen may include a transition button associated with a command for transitioning to another operation screen. When the process proceeds from step S15 described later, an operation screen is displayed on the LCD 165. When the operation screen instructing the transition button is detected by the touch panel 169 in a state where the operation screen is displayed on the LCD 165, it is determined that the operation screen associated with the transition button has been selected. If the operation screen is selected, CPU 111 advances the process to step S03, and if not, advances the process to step S04.

  In step S03, the selected operation screen is displayed on LCD 165, and the process proceeds to step S04. In step S04, it is determined whether an operation has been detected. If an operation is detected, the process proceeds to step S05; otherwise, the process returns to step S02. The CPU 111 detects an operation by executing an operation detection process described later. Here, a case will be described as an example in which operations detected by the CPU 111 by executing the operation detection process include a scroll operation, a selected image instruction operation, and other operations. The scroll operation is an operation for instructing a scroll instruction acceptance image included in the operation screen. The selected image instruction operation is an operation for instructing a selected image included in the operation screen. Other operations are operations other than the scroll operation and the selected image instruction operation. Other operations include an end instruction operation for instructing the end of the operation reception process.

  In step S05, it is determined whether or not the operation detected in step S04 is a scroll operation. If a scroll operation is detected, the process proceeds to step S06; otherwise, the process proceeds to step S09. In step S06, the scroll direction is determined based on the detected scroll operation. The scroll operation includes a feed instruction and a return instruction. If it is a feed instruction, the scroll direction is determined to be a direction including the selected image in the next order, and if it is a return instruction, the scroll direction is determined to be a direction including the previous selected image. In the next step S07, the number N of selectable images including the selected images in the order determined by the scroll direction is selected. Then, the selected arrangement number N selected images are displayed in the scroll area in the operation screen (step S08), and the process returns to step S02. Specifically, when the operation screen is displayed, the first to Nth selected images are selected and arranged side by side in the scroll area. When a scroll operation indicating a feed instruction is detected, selection of the arrangeable number N including the selected images whose order is later than any of the selectable number N of selected images selected when the scroll operation is detected Select an image and place it side by side in the scroll area. For example, when the N-th selectable arrangement images from the first to the N-th are displayed at the time of selection when the scroll operation is detected, the first to N-th selection images are displayed. N selected images including the (N + 1) th selected image after the last Nth selected image, for example, the second to (N + 1) th selected images, Arrange them in the scroll area. Further, when a scroll operation indicating a return instruction is detected, the number of arrangeable numbers including the selected image whose order is earlier than any of the selectable number N of selectable images selected when the scroll operation is detected. Select the selected image and place it side by side in the scroll area. For example, when the second to (N + 1) th selected images selected when the scroll operation is detected are displayed, the first of the second to (N + 1) th selected images is displayed. N selected images including the first selected image in the order before the second selected image, for example, the first to Nth selected images are selected and arranged side by side in the scroll area.

  In step S09, it is determined whether or not the operation detected in step S04 is a selected image instruction operation. If a selected image instruction operation is detected, the process proceeds to step S10. If not, the process proceeds to step S14. The selected image instruction operation is an operation in which the user instructs any one of N arrangement images that can be arranged displayed in the scroll area. In step S10, the selected image determined by the selected image instruction operation is specified. In other words, the selection image instructed by the user is specified from among the N arrangementable selection images displayed in the scroll area. Then, it is determined whether or not the state of the specified selected image has been switched (step S11). If the state of the selected image has been switched, the process proceeds to step S12. If not, the process proceeds to step S13. In step S13, the state of the selected image specified in step S10 is switched, and the process returns to step S02. For example, the display mode of the selected image is made different from the display mode of other selected images. When the selected image is associated with a command for displaying another window, the command is executed and another window is displayed. On the other hand, in step S12, the state of the selected image is returned to the original state. For example, when the display mode is switched, the same display mode as that of other selected images is set. If another window is displayed by executing a command associated with the selected image, the window is closed.

  In step S14, it is determined whether or not the operation detected in step S04 is an end instruction operation. If it is an end instruction operation, the process ends. If not, the process proceeds to step S15. In step S15, a predetermined process corresponding to the operation detected in step S04 is executed, and the process returns to step S02. The processing predetermined in response to the operation detected in step S04 is not limited, but is, for example, processing for switching to another operation screen, processing for executing a job, or the like.

  FIG. 7 is a flowchart illustrating an example of the flow of the reception mode switching process. The reception mode switching process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes an operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. The CPU 111 executes a reception mode switching process in parallel with the operation reception process described above. Referring to FIG. 7, CPU 111 switches the reception mode to the normal mode (step S41). In the next step S42, an initial value “0” is set to the variable C. The variable C is a variable for counting the number of times that the user designates the scroll instruction acceptance image or the extension area.

  In step S43, it is determined whether or not touch panel 169 has detected a position designated by the user on the display surface of LCD 165. If the position is detected, the process proceeds to step S44; otherwise, the process proceeds to step S53. In step S53, it is determined whether an operation by the user is detected. For example, it is determined whether an operation for instructing the hard key unit 170 or an operation for placing a document on the automatic document feeder 120 is accepted. If an operation by the user is detected, the process proceeds to step S51. If not, the process returns to step S43.

  In step S44, it is determined whether or not the position detected in step S43 is within the scroll instruction accepting image or the extended area on the operation screen. If the touch panel 169 detects the position inside either the scroll instruction acceptance image or the extended area, the process proceeds to step S45; otherwise, the process proceeds to step S53. In step S45, variable C is incremented and the process proceeds to step S46. In step S46, it is determined whether the value of variable C is 2 or more. If the value of variable C is 2 or more, the process proceeds to step S47; otherwise, the process proceeds to step S47. When the value of the variable C is 2 or less, either the scroll instruction acceptance image or the extension area is first designated by the user. In step S47, timer T is started, and the process returns to step S43. The timer T measures the elapsed time after the touch panel 169 detects the position designated by the user.

  The process proceeds to step S48 when the value of the variable C is 2 or more, and when the user instructs either the scroll instruction acceptance image or the extended area twice or more. In step S48, it is determined whether or not the value of timer T is equal to or less than a threshold value. If the value of timer T is equal to or smaller than the threshold value, the process proceeds to step S49; otherwise, the process proceeds to step S51. The threshold value is a predetermined value, and is the maximum value of the interval to be instructed when the user continuously indicates the scroll instruction acceptance image or the extended area. For example, the interval at which the user continuously indicates the scroll instruction acceptance image or the extended area may be stored as a history, and the threshold value may be determined using the history. The maximum value of the interval stored as the history is preferable. If the user is different, the interval for continuously indicating the scroll instruction acceptance image or the extended area is different, and therefore the interval for the continuous operation is made different for each user by using a threshold corresponding to the user who operates the MFP 100. be able to.

  In step S49, the reception mode is switched to the enlargement mode, and the process proceeds to step S50. In step S50, as in step S47, the timer T is started, and the process returns to step S43.

  In step S51, the reception mode is switched to the normal mode, and the process proceeds to step S52. In step S52, an initial value “0” is set in variable C, and the process returns to step S43. If the process proceeds to step S51, if it is determined in step S44 that the position instructed by the user is neither the scroll instruction acceptance image nor the extended area, the value of timer T is greater than the threshold value in step S48. When it is determined that the value is large, or when a user operation is detected in step S53. When the value of the timer T is larger than the threshold value, the interval from when the user designates the scroll instruction acceptance image or the extension area until the next designation of the scroll instruction acceptance image or the extension area is larger than the threshold value In this case, it is not determined that the user has instructed the scroll instruction acceptance image or the extended area continuously. In addition, when the user instructs a position different from both the scroll instruction acceptance image and the extension area, or when the user performs an operation different from the operation that instructs the touch panel 169, the timer T is equal to or less than the threshold value. Even if it exists, it is not determined that the user has instructed the scroll instruction acceptance image or the extended area continuously.

  FIG. 8 is a flowchart illustrating an example of the flow of the operation detection process. The operation detection process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes an operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. The CPU 111 executes the operation detection process in parallel with the operation reception process and the reception mode switching process described above. Therefore, the acceptance mode is switched between the normal mode and the enlargement mode by the CPU 111 executing the acceptance mode switching process. Referring to FIG. 8, CPU 111 determines whether touch panel 169 has detected a position designated by the user on the display surface of LCD 165 (step S21). The process waits until the position is detected (NO in step S21). If the position is detected (YES in step S21), the process proceeds to step S22.

  In step S22, the process branches depending on the reception mode. If the acceptance mode is switched to the normal mode, the process proceeds to step S23. If the acceptance mode is switched to the enlargement mode, the process proceeds to step S28.

  In step S23, it is determined whether or not the position detected in step S21 is within the scroll instruction acceptance image on the operation screen. If the position inside the scroll instruction acceptance image is detected by touch panel 169, the process proceeds to step S24; otherwise, the process proceeds to step S25. In step S24, a scroll operation is detected, and the process returns to step S21. The scroll operation includes a scroll operation indicating a feed instruction and a scroll operation indicating a return instruction. A scroll operation associated with the scroll instruction acceptance image including the position detected in step S21 is detected.

  In step S25, it is determined whether or not the position detected in step S21 is within the selected image on the operation screen. If the position inside the selected image is detected by touch panel 169, the process proceeds to step S26. If not, the process proceeds to step S27. In step S26, a selected image instruction operation is detected, and the process returns to step S21. In step S27, other operations are detected, and the process returns to step S21. For example, an operation associated with the position detected in step S21 in the operation screen is detected. Specifically, if the position detected in step S21 in the operation screen is within the transition button, an operation for displaying the operation screen associated with the transition button is detected. If there is no operation associated with the position detected in step S21 in the operation screen, the process directly returns to step S21.

  The process proceeds to step S28 when the acceptance mode is switched to the enlargement mode. In step S28, it is determined whether or not the position detected in step S21 is within the scroll instruction acceptance image on the operation screen. If the position inside the scroll instruction acceptance image is detected by touch panel 169, the process proceeds to step S29; otherwise, the process proceeds to step S30. In step S29, a scroll operation is detected as in step S24, and the process returns to step S21.

  In step S30, it is determined whether or not the position detected in step S21 is within the selected image on the operation screen. If the position inside the selected image is detected by touch panel 169, the process proceeds to step S31. If not, the process proceeds to step S33. In step S31, it is determined whether or not the position detected in step S21 is within the extended area in the operation screen. If the position inside the extended area is detected by touch panel 169, the process proceeds to step S32. If not, the process proceeds to step S32. In step S32, a scroll operation is detected as in step S24, and the process returns to step S21. In step S32, the selected image instruction operation is detected, and the process returns to step S21. In step S33, other operations are detected as in step S27, and the process returns to step S21.

  As described above, MFP 100 according to the first embodiment functions as an electronic device, and touch panel 169 has a continuous position in the scroll instruction reception image or an extended area in the operation screen displayed on LCD 165. The reception mode is switched from the normal mode to the enlargement mode in response to the detection more than a predetermined number of times, and the scroll instruction reception image is displayed on the touch panel 169 regardless of whether the reception mode is switched to the normal mode or the enlargement mode. When a position in the expansion area is detected, an operation for instructing a scroll instruction reception image is detected. In a state where the reception mode is switched to the enlargement mode, a scroll instruction is issued when a position in the expansion area is detected by the touch panel 169. An operation for designating a reception image is detected. For this reason, when the user instructs the scroll instruction acceptance image continuously for a predetermined number of times or more, even if the user mistakenly designates the periphery of the scroll instruction acceptance image, the user continuously instructs the scroll instruction acceptance image. Can be entered.

  Further, in the state where the reception mode is switched to the enlargement mode, the MFP 100 determines whether the position in the scroll instruction reception image or the position in the extended area continuously detected by the touch panel 169 from before the change to the enlargement mode is performed on the touch panel 169. When it is not detected, the reception mode is switched from the enlargement mode to the normal mode. For this reason, the reception mode while the scroll instruction reception image or the position in the expansion area is continuously detected can be switched to the enlargement mode.

  In addition, MFP 100 switches the reception mode from the expansion mode to the normal mode when a time determined as a threshold has elapsed since the position in the scroll instruction reception image or the position in the expansion area has been detected last by touch panel 169. . For this reason, it is possible to detect the end of the operation of continuously instructing the scroll instruction acceptance image or the extended area.

  In addition, MFP 100 stores, as history information for each user, an interval at which a position in a scroll instruction acceptance image or a position in an extended area is continuously detected by touch panel 169, and a threshold is set based on the stored history information. To decide. For this reason, it is possible to vary the interval of the operation for continuously instructing the scroll instruction acceptance image or the extended area for each user.

  Further, MFP 100 changes N selection images displayed in the scroll area in response to detection of an operation for instructing a scroll instruction reception image, and in a state where the reception mode is switched to the normal mode, When the touch panel 169 detects the internal position of any of the N selected images, an operation for instructing the selected image is detected. When the reception mode is switched to the enlargement mode, the N selected images are detected. When a position other than the overlapping area that overlaps the extension area is detected, an operation for instructing the selected image is detected. If a position in the overlapping area is detected, the selected image is indicated. Does not detect operations. For this reason, when the user instructs the scroll instruction acceptance image continuously for a predetermined number of times or more, even if the user mistakenly designates the periphery of the scroll instruction acceptance image and the inside of the selected image, the scroll instruction acceptance image is displayed. An operation for instructing continuously can be input.

  In addition, MFP 100 switches the selected image to either the first state or the second state in response to detection of an operation for instructing the selected image, and the position in the overlapping region is continuously displayed by touch panel 160. The reception mode is switched from the normal mode to the enlargement mode in response to the even number of times being detected. For this reason, when the state of the selected image is either the first state or the second state, the reception mode can be switched to the enlargement mode.

<Modification of mode switching>
When the touch panel 169 continuously detects a position in the scroll instruction receiving image or a position in the extended area for a predetermined number of times or more, the mode switching unit 51 in the modification example continues the position in the scroll instruction receiving image or the position in the extended area. The reception mode is switched to the enlargement mode. The mode switching unit 51 in the modified example accepts the reception when the touch panel 169 detects a position different from the position in the scroll instruction reception image or the position in the expansion area after switching the reception mode to the enlargement mode. Switch the mode to normal mode.

  The MFP 100 in the modified example has a position different from the position in the scroll instruction acceptance image or the position in the extension area by the touch panel 169 after the position in the scroll instruction acceptance image or the position in the extension area is finally detected by the touch panel 169. When is detected, the reception mode is switched from the enlargement mode to the normal mode. For this reason, it is possible to detect the end of the operation of continuously instructing the scroll instruction acceptance image or the extended area.

  In addition, the mode switching unit 51 in the modified example switches the reception mode to the normal mode when an operation other than the operation of instructing the touch panel 169 is detected after switching the reception mode to the enlargement mode. Operations other than the operation of instructing the touch panel 169 include, for example, an operation of instructing the hard key unit 170, an operation of placing a document on the automatic document feeder 120, and an operation of enlarging a part of the operation screen.

  The MFP 100 according to the modified example changes the reception mode from the enlarged mode when an operation other than an operation for instructing the touch panel 169 is received after the position in the scroll instruction reception image or the position in the extended area is finally detected by the touch panel 169.

<Second Embodiment>
MFP 100 in the second modification is configured to accept a scroll instruction by long-pressing a scroll instruction accepting image or an extended area. Here, the long press refers to an operation of continuously instructing a scroll instruction acceptance image or an extended area for a second time.

  The appearance and hardware configuration of MFP 100 in the second embodiment are the same as the appearance and hardware configuration shown in FIGS. 1 and 2, respectively. Further, a plan view of operation panel 160 provided in MFP 100 in the second embodiment is the same as the plan view shown in FIG.

FIG. 9 is a block diagram illustrating an example of functions of a CPU included in the MFP according to the second embodiment. The functions shown in FIG. 9 are functions realized by CPU 111 when CPU 111 provided in MFP 100 executes an operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. Referring to FIG. 9, CPU 111 includes a mode switching unit 51A, an instruction detection unit 53A, and an operation screen display unit 57. Operation screen display unit 57 is the same as operation screen display unit 57 included in CPU 111 provided in MFP 100 according to the first embodiment. Therefore, description is not repeated here.
The mode switching unit 51A switches the reception mode between the normal mode and the enlargement mode based on the position on the display surface of the LCD 165 detected by the touch panel 169, and outputs the reception mode to the instruction detection unit 53A. The mode switching unit 51A receives the position of the scroll instruction reception image on the display surface of the LCD 165 from the instruction reception image display unit 61A. Touch panel 169 detects the position instructed by the user when the user indicates the display surface of LCD 165.

  The mode switching unit 51A switches the reception mode to the normal mode when the operation screen is displayed. Further, after the operation screen is displayed, the mode switching unit 51A detects the position in the extension area around the scroll instruction reception image continuously for the first time, and then changes the reception mode from the normal mode to the expansion mode. Switch to. Although not limited, the extension area is an area around the scroll instruction acceptance image, for example, an area within a predetermined distance range from the scroll instruction acceptance image. Since the scroll instruction acceptance image is arranged in the vicinity of the scroll area, at least a part of the extension area may overlap with a part of the selected image. The mode switching unit 51 switches the reception mode from the expansion mode to the normal mode after the reception mode is switched to the expansion mode and the touch panel 169 continues to detect that the position in the expansion area is instructed. Switch.

  The touch panel 169 detects the position while the user touches the display surface of the LCD 165. However, the instruction detection unit 53A does not use the position at that time, and the touch panel 169 is used when the user lifts the finger from the display surface of the LCD 165. The position detected by is used. In other words, the instruction detection unit 53A uses the position detected last when the touch panel 169 no longer detects the position from when the touch panel 169 detects the position until it stops detecting the position.

  The instruction detection unit 53A receives the position of the scroll instruction reception image on the display surface of the LCD 165 from the instruction reception image display unit 61, and the selection image identification information of each of the selectable number N of selected images from the selection image display unit 63 and the LCD 165. The position on the display surface is input, and the acceptance mode is input from the mode switching unit 51A. When the reception mode is the normal mode, the instruction detection unit 53A instructs the selected image including the detected position when the position detected last by the touch panel 169 is inside any of the selectable number N of selected images. A selected image instruction operation is detected. When detecting the selected image instruction operation, the instruction detection unit 53A outputs the selection instruction to the selected image display unit 63 and the state switching unit 65. The selection instruction includes selected image identification information of a selected image including a position detected by the touch panel 169.

  When the acceptance mode is the normal mode and the position detected last by the touch panel 169 is inside the scroll instruction image, the instruction detection unit 53A detects a scroll operation that instructs the scroll instruction image including the detected position. In addition, when the reception mode is the normal mode, the instruction detection unit 53A detects the position detected by the touch panel 169 every time the second time elapses after the touch panel 169 detects the position inside the scroll instruction image. A scroll operation that indicates a scroll instruction image is detected. The second time is not limited, but is preferably longer than the first time. The instruction detection unit 53 </ b> A detects a scroll operation every time the second time elapses, and outputs a scroll instruction to the selected image display unit 63. The scroll instruction includes a feed instruction and a return instruction. When the position in the scroll instruction acceptance image corresponding to the feed instruction is detected, the instruction detection unit 53A outputs a scroll instruction indicating the feed instruction to the selection image display unit 63, and the scroll instruction acceptance image corresponding to the return instruction. When the position is detected, a scroll instruction indicating a return instruction is output to the selected image display unit 63.

  When the reception mode is the extended mode, the instruction detection unit 53A, when the position inside the scroll instruction image is continuously detected by the touch panel 169, the second time elapses as in the case where the reception mode is the normal mode. Scroll operation is detected every time. In addition, when the reception mode is the expansion mode, the instruction detection unit 53A detects that the position within the expansion area corresponding to the scroll instruction image is continuously detected by the touch panel 169 for the second time or more, and then the second time A scroll operation is detected every time when the reception mode is the normal mode.

  The extended area may overlap with a part of the selected image. When the reception mode is the expansion mode, the instruction detection unit 53A, when the touch panel 169 detects the position within the expansion area and the position within the selection image, the selection image instruction operation for instructing the selection image including the detected position Without detecting this, a scroll operation that indicates a scroll instruction image corresponding to the extended region including the detected position is detected. The scroll instruction acceptance image corresponding to the extension area is a scroll instruction acceptance image arranged inside the extension area. When the acceptance mode is the expansion mode, the instruction detection unit 53A selects a selection image that includes the detected position when the touch panel 169 detects a position in the selection image that is a position other than the expansion area. An image instruction operation is detected.

  10 and 11 are flowcharts showing an example of the flow of the mode switching / operation detection process. The mode switching / operation detection process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes an operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. The CPU 111 in the second embodiment executes mode switching / operation detection processing in parallel with operation reception processing. Referring to FIG. 10 and FIG. 11, CPU 111A in the second embodiment determines whether touch panel 169 has detected a position designated by the user on the display surface of LCD 165 (step S61). The process waits until the position is detected (NO in step S61). If the position is detected (YES in step S61), the process proceeds to step S62. In step S62, timer T1 is started and the process proceeds to step S63. In step S63, timer T2 is started and the process proceeds to step S64. The timer T1 and the timer T2 measure the time after the scroll instruction acceptance image or the extended area is instructed by the user.

In step S64, it is determined whether or not the position detected in step S61 is within the scroll instruction acceptance image on the operation screen. If the position inside the scroll instruction acceptance image is detected by touch panel 169, the process proceeds to step S65; otherwise, the process proceeds to step S71. In step S65, it is determined whether or not the value of timer T2 is the second time. If the value of timer T2 is the second time, the process proceeds to step S66; otherwise, the process proceeds to step S68.
In step S66, a scroll operation is detected, and the process proceeds to step S67. The scroll operation includes a scroll operation indicating a feed instruction and a scroll operation indicating a return instruction. A scroll operation associated with the scroll instruction acceptance image including the position detected in step S61 is detected. In step S67, timer T2 is reset, and the process returns to step S65.

  In step S68, it is determined whether or not position detection is completed. When the position detected by the touch panel 169 is no longer detected, it is determined that the position detection is finished. If the position detection is completed, the process proceeds to step S69. If not, the process returns to step S65. In step S69, it is determined whether or not the value of timer T1 is smaller than the second time. If the value of timer T1 is smaller than the second time, the process proceeds to step S70; otherwise, the process returns to step S61. In step S70, as in step S66, a scroll operation is detected, and the process returns to step S61. A scroll instruction is detected when the user instructs a scroll instruction acceptance image and releases his / her finger from the display surface of the LCD 165 before the second time elapses.

  In step S71, it is determined whether or not the position detected in step S61 is within the extended area in the operation screen. If the position inside the extension area is detected by touch panel 169, the process proceeds to step S72; otherwise, the process proceeds to step S82. In step S72, it is determined whether or not the value of timer T1 is equal to or greater than the first time. If the value of timer T1 is equal to or greater than the first time, the process proceeds to step S73. If not, step S73 is skipped and the process proceeds to step S74. In step S73, the reception mode is switched to the enlargement mode, and the process proceeds to step S74.

In step S74, it is determined whether or not the value of timer T2 is the second time. If the value of timer T2 is the second time, the process proceeds to step S75; otherwise, the process proceeds to step S77.
In step S75, a scroll operation is detected as in step S66, and the process proceeds to step S76. In step S76, the timer T2 is reset, and the process returns to step S74.

  In step S77, it is determined whether or not position detection is completed. When the position detected by the touch panel 169 is no longer detected, it is determined that the position detection is finished. If the position detection is completed, the process proceeds to step S78; otherwise, the process returns to step S72. In step S78, it is determined whether or not the reception mode is switched to the enlargement mode. If the reception mode is the enlargement mode, the process proceeds to step S79; otherwise, the process proceeds to step S80. In step S78, the acceptance mode is switched to the normal mode, and the process returns to step S61.

  In step S80, it is determined whether or not the position detected in step S61 is within the selected image on the operation screen. If the position inside the selected image is detected by touch panel 169, the process proceeds to step S81. If not, the process proceeds to step S84. In step S81, a selected image instruction operation is detected, and the process returns to step S61.

  On the other hand, when the process proceeds to step S82, the position detected in step S61 is neither the scroll instruction acceptance image nor the extension area in the operation screen. In step S82, as in step S77, it is determined whether or not position detection has ended. If the position detection is completed, the process proceeds to step S83; otherwise, the process returns to step S64. In step S83, it is determined whether or not the position detected in step S61 is within the selected image on the operation screen. If the position inside the selected image is detected by touch panel 169, the process proceeds to step S84. If not, the process proceeds to step S85. In step S84, a selected image instruction operation is detected, and the process returns to step S61.

  In step S85, other operations are detected, and the process returns to step S61. For example, the operation associated with the position detected in step S61 in the operation screen is detected. For example, if the position detected in step S61 in the operation screen is within the transition button, the operation associated with the transition button is detected. Detects operations that display the screen. If there is no operation associated with the position detected in step S61 in the operation screen, the process directly returns to step S61.
