Description

  The present invention relates to an electronic device, an instruction receiving method, and an operation receiving program, and more particularly to an electronic device capable of scroll-displaying a plurality of objects, an instruction receiving method and an operation receiving program executed by the electronic device.

  In recent years, a touch panel is used as a user interface in an image forming apparatus such as a multifunction peripheral (MFP). By using the touch panel, various operations can be received in combination with an image displayed on the screen. For example, when there is no space for displaying all of the plurality of objects on the screen, a part of the plurality of objects may be displayed at different times, so-called scroll display. In this case, the scroll button is displayed on the screen, and the object displayed on the screen is changed in response to detection of the position in the scroll button by the touch panel. The scroll button is displayed when scrolling is possible, may not be displayed when the object cannot be scrolled, and may be displayed superimposed on the object when the scroll button is displayed. While the user is continuously touching the scroll button, the scroll button may not be displayed. In this case, an operation in which the user touches the scroll button is detected as a touch on the object. There's a problem.

  For example, Japanese Patent Laid-Open No. 2013-3749 includes a display unit, a copy key, a copy cancel key, and a CPU. The copy key is displayed on the display unit, and when an input operation is received, the corresponding function is exhibited and copying is performed. The cancel key is displayed on the display unit 10. When an input operation is accepted, the cancel key performs a function different from that of the copy key. When the copy key is valid, the cancel key is invalid. When the copy key is displayed, the cancel key is displayed. In the first stage after the copy key accepts the input operation, the CPU 40 disables the copy key and the copy cancel key, hides the copy key, and displays the copy cancel key. In the second stage, an image forming apparatus is described in which the copy cancel key is enabled.

However, the image forming apparatus described in Japanese Patent Application Laid-Open No. 2013-3749 disables the copy key and the copy cancel key, so that an erroneous operation can be prevented. Since it is not accepted, there is a problem that the response to the operation by the user becomes slow.

  The present invention has been made to solve the above-described problems, and one of the objects of the present invention is to provide an electronic apparatus that prevents erroneous operation when the same position is successively indicated.

  Another object of the present invention is to provide an operation reception method that prevents erroneous operation when the same position is continuously indicated.

  Still another object of the present invention is to provide an operation reception program that prevents erroneous operations when the same position is successively indicated.

  In order to achieve the above-described object, according to one aspect of the present invention, an electronic device includes a display unit that can display an image, and a position detection unit that detects a position instructed by a user on the display surface of the display unit. Selection image display means for selecting a predetermined number of selection images that are consecutive in order from a plurality of selection images assigned a predetermined order and displaying the selected predetermined number of selection images side by side in a scroll area; A scroll instruction is accepted in one of the two overlapping regions respectively included at both ends of the scroll region, provided that the first selected image among the plurality of selected images is not included in the predetermined number of selected images. An image is displayed, and a scroll instruction acceptance image is displayed on the other of the two overlapping regions on the condition that a selected image in the last order among a plurality of selected images is not included in a predetermined number of selected images. Mode for switching the reception mode from the normal mode to the continuous mode when the position inside the two overlapping areas is continuously detected a predetermined number of times or more by the position detection means. When the position detecting unit detects the position inside either of the two overlapping regions in the normal mode when the reception mode is the switching unit, the overlapping includes the position detected by the position detecting unit in the two overlapping regions. If the scroll instruction acceptance image is displayed in the area, the scroll operation is detected. If the scroll instruction acceptance image is not displayed, the position detected by the position detection means among the predetermined number of selection images displayed in the scroll area is detected. A selection image instruction operation that identifies a selection image to be included is detected, and the reception mode is in the continuous mode, and one of the two overlapping regions is detected. When the position is detected by the position detection means, the scroll operation is detected regardless of whether or not the scroll instruction acceptance image is displayed in the overlap area including the position detected by the position detection means of the two overlap areas. An instruction detecting means, and the selected image display means is in the order before or before any of the predetermined number of selected images selected at the time when the scroll operation is detected in response to the detection of the scroll instruction. A predetermined number of selection images including a subsequent selection image are selected.

  According to this aspect, a predetermined number of selection images are displayed side by side in the scroll area, and on the condition that the selection image in the first order is not included, one of the two overlapping areas respectively included at both ends of the scroll area. The scroll instruction acceptance image is displayed, and the scroll instruction acceptance image is displayed on the other of the two overlapping areas on the condition that the selection image in the last order is not included. Detected when the reception mode is switched from the normal mode to the continuous mode in response to being continuously detected a predetermined number of times or more and the position inside one of the two overlapping regions is detected in the normal mode. If the scroll instruction acceptance image is displayed in the superimposed area including the position, the scroll operation is detected. If the scroll instruction acceptance image is not displayed, the detected position is Detecting a selected image instruction operation to identify the non-selected image, if any of the interior of the positions of the two overlapping area is detected in the continuous mode, detecting a scrolling operation. For this reason, when the user instructs the scroll instruction acceptance image continuously for a predetermined number of times or more, the user mistakenly designates the overlapping area where the scroll instruction acceptance image is displayed after the scroll instruction image is not displayed. However, since the selected image instruction operation for specifying the selected image displayed in the superimposed area is not detected, an operation for instructing the scroll instruction acceptance image can be input. As a result, it is possible to provide an electronic device that prevents an erroneous operation when continuously instructing the same position.

  Preferably, when the reception mode is the continuous mode and the selection image of the first or last order among the plurality of selection images is included in the predetermined number of selection images, the scroll instruction reception image is set in the scroll area. Operation support means for displaying is further provided.

  According to this aspect, when the selection image in the first or last order is included in the continuous mode state, the scroll instruction acceptance image is displayed in the scroll area. Can be notified to the user.

  Preferably, the selected image display means selects a selected image even if a scroll operation is detected after selecting a predetermined number of selected images including the first or last selected image among the plurality of selected images. do not do.

  Preferably, when the position detection unit detects a position inside one of the two overlapping regions in the state where the reception mode is the continuous mode, the instruction detection unit first selects the first of the plurality of selection images from the selection image display unit. Alternatively, the scroll operation is detected until a predetermined number of selection images including the selection image in the last order are selected, and a predetermined number of selection images including the first or last selection image among the plurality of selection images by the selection image display unit. The scroll operation is not detected after the selected image is selected.

  Preferably, in the state where the reception mode is switched to the continuous mode, the mode switching means detects the position of one of the two overlapping areas detected continuously by the position detection means before switching to the continuous mode. When it is not detected by the means, the reception mode is switched from the continuous mode to the normal mode.

  According to this aspect, in the state in which the mode is switched to the continuous mode, the mode is switched to the normal mode when the position in the overlapped area continuously detected before switching to the continuous mode is not detected. For this reason, the reception mode can be switched to the continuous mode only while the position in the overlapping region is continuously detected.

  Preferably, the mode switching unit switches the reception mode from the continuous mode to the normal mode when a predetermined time or more has elapsed since the position detection unit finally detected the position in one of the two overlapping regions.

  According to this aspect, since the mode is switched to the normal mode when a predetermined time or more has elapsed since the position in the superposition region was last detected, it is possible to detect the end of the operation for continuously instructing the superposition region.

  Preferably, the position detection means stores the interval at which the position detection means continuously detects the internal position of one of the two overlapping regions as history information for each user, and sets a predetermined time based on the stored history information. Threshold value determining means for determining is further provided.

  According to this aspect, an interval for continuously detecting the position in the overlapping area is stored as history information for each user, and a predetermined time is determined based on the history information. The interval can be different for each user.

  Preferably, the mode switching means is set to 2 by the position detection means before the first time elapses after the position detection means detects the internal position of one of the two overlapping regions in the normal mode. The reception mode is switched to the continuous mode in response to the detection of the position inside one of the two overlapping regions. When the reception mode is the continuous mode, the position detection unit determines the position inside one of the two overlapping regions. When a second time longer than the first time has elapsed since detection, the reception mode is switched to the normal mode.

  According to this aspect, the interval between two consecutive operations that are the conditions for switching from the continuous mode to the normal mode is longer than the interval between the two consecutive operations that are the conditions for switching to the continuous mode. Can be made as long as possible.

  Preferably, an interval at which the position detection unit continuously detects the position in one of the two overlapping regions is stored as history information for each user, and the first information is stored based on the stored history information. Threshold value determining means for determining time is further provided.

  According to this aspect, since the interval at which the position in the superimposed region is continuously detected is stored as history information for each user and the first time is determined based on the history information, the instruction reception image or the extension region is The interval between operations to be instructed continuously can be varied for each user.

  Preferably, in the state where the reception mode is the continuous mode, the first or last selected image is selected in response to the selection of the first or last selected image from the plurality of selected images by the selected image display means. Notification means for notifying selection is further provided.

  According to this aspect, in the state of the continuous mode, in response to the selection of the first or last selected image in order, it is notified that the first or last selected image has been selected. For this reason, it is possible to notify the user that the scroll operation cannot be input.

  Preferably, when the reception mode is the continuous mode, the number of times that the scroll instruction detecting unit can detect the selected image display unit until the first or last selected image is selected from the plurality of selected images is displayed. The display device further includes a number-of-times display means.

  According to this aspect, since the number of times the scroll operation can be detected is displayed before the first or last selected image is selected, the user can be notified of the number of times the scroll operation can be performed.

  Preferably, the plurality of selected images have the same size, and the size of the scroll instruction receiving image is smaller than the size of the plurality of selected images.

Touch panel 169 detects the position indicated by the user with a finger or a stylus pen, and outputs the coordinates of the detected position to input control unit 167. Touch panel 169 is preferably the same size or larger than the display surface of LCD 165. Since the touch panel 169 is provided so as to overlap with the LCD 165, the touch panel 169 outputs the coordinates of the position designated by the user on the display surface of the LCD 165 to the input control unit 167 when the user indicates the display surface of the LCD 165. As the touch panel, for example, a resistive film method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, and a capacitance method can be used, and the method is not limited.

  When there is a hard key that outputs an ON signal in the hard key unit 170, the input control unit 167 outputs identification information of the hard key that outputs the ON signal to the CPU 111. Further, when the touch panel 169 detects the position designated by the user, the input control unit 167 outputs the coordinates output from the touch panel 169 to the CPU 111.

  The external storage device 117 is controlled by the CPU 111, and a CD-ROM (Compact Disk Read Only Memory) 118 or a semiconductor memory is mounted.

Referring to FIG. 3, operation panel 160 includes LCD 165, touch panel 169 provided so as to overlap LCD 165, and start key 171, BOX key 173, COPY key 175, and FAX key 177 on the right side and lower side of LCD 165. And a hard key unit 170 on which a plurality of hard keys are arranged.

  FIG. 4 is a block diagram illustrating an example of functions of the CPU provided in the MFP according to the present embodiment. The functions shown in FIG. 4 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. 4, CPU 111 includes a mode switching unit 51, an instruction detection unit 53, a threshold value determination unit 55, and an operation screen display unit 57.

  The operation screen display unit 57 outputs the operation screen to the display control unit 161 and causes the display control unit 161 to display an image of the setting screen on the LCD 165. Here, the operation screen displayed on the LCD 165 by the operation screen display unit 57 includes a scroll area. The scroll area is an area in which a partial set of a plurality of selected images associated with the operation screen is displayed in a changeable manner.

  The operation screen display unit 57 includes an instruction acceptance image display unit 61, a selection image display unit 63, a state switching unit 65, an operation support unit 67, a frequency display unit 69, and a notification unit 71. The selected image display unit 63 displays a plurality of selected images associated with the operation screen side by side in the scroll area. The plurality of selected images are assigned a predetermined order and all have the same size. Since the size of the scroll area is determined by the operation screen, the number of the plurality of selected images that can be arranged in the scroll area is determined by the size of the scroll area. Here, the number of selected images that can be arranged in the scroll area is referred to as an arrangementable number, and is represented by a constant N. However, N is an integer greater than 1. The selected image display unit 63 selects the arrangement images N in the number of arrangement images that can be arranged sequentially from the plurality of selection images corresponding to the operation screen, and displays the selected images in the arrangement area N in the scroll area. To do. When displaying the selectable number of select images in the scroll area, the select image display unit 63 selects select image identification information for identifying the select image for each selectable number N of select images and the LCD 165 of the select image. The position on the display surface is output to the instruction detection unit 53. Further, when displaying the selectable number N of select images in the scroll area, the select image display unit 63 displays the select image identification information for identifying the select image for each of the selectable number N of select images. 67 and the number of times display portion 69.

  At the stage where the operation screen is displayed, the selected image display unit 63 selects the first to Nth selected images and arranges them in the scroll area. The selected image display unit 63 has a higher order than any of the selectable arrangement images selected at the time when the scroll operation is detected in response to the scroll operation being input from the instruction detection unit 53 described later. The selectable number N of selected images including the previous or subsequent selected images are selected and arranged side by side in the scroll area. The number of selected images whose order is shifted forward or backward can be arbitrarily determined from the numbers from 1 to N. However, N is an integer greater than 1. Here, the number of selected images is M, and the number of selected images to be shifted forward or backward is “1”. However, M is an integer larger than N.

  The scroll operation includes a feed instruction and a return instruction. Specifically, the selected image display unit 63 selects N displayable images from the first to the Nth, and scrolls indicating a sending instruction from the instruction detection unit 53 at the stage of display. N selections including the (N + 1) th selected image after the last Nth selected image among the first to Nth selected images in response to an operation being input Images, for example, the second to (N + 1) th selected images are selected and arranged side by side in the scroll area. In addition, the selection image display unit 63 selects a second to (N + 1) th selection image and displays a scroll operation indicating a return instruction from the instruction detection unit 53 at the stage of display. Accordingly, among the second to (N + 1) th selected images, N selected images including the first selected image whose order is earlier than the first second selected image, for example, the first The Nth selected image is selected and arranged side by side in the scroll area.

  When a scroll operation indicating a return instruction is input, the selected image display unit 63 does not select the arrangement number N of selected images when the first selected image is displayed in the scroll area at that time. . In addition, when a scroll operation indicating a feed instruction is input, the selected image display unit 63 displays a selection image of N arrangementable numbers when the last selected image is displayed in the scroll area. Do not select.

  The instruction acceptance image display unit 61 displays a scroll instruction acceptance image for accepting a scroll operation at each of both ends of the scroll region. Hereinafter, an area in which the scroll instruction acceptance image is displayed in the scroll area is referred to as a superimposed area. 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.

  In the scroll area, the selected image display unit 63 displays N selectable images. For this reason, two selection images respectively displayed at both ends of the scroll area among the selectable number N of selection images displayed in the scroll area each overlap at least one of the two overlapping areas. There is. The instruction reception image display unit 61 displays the scroll instruction reception image in each of the two overlapping areas of the scroll area. If a part of the selection image is displayed in the overlapping area, the instruction reception image display unit 61 has priority over the selection image. To display.

  The instruction reception image display unit 61 returns to the superimposition area and does not display the scroll instruction reception image indicating the instruction when the arrangement number N of selection images displayed in the scroll area includes the first selection image. This is because it is not necessary to accept a scroll operation indicating a return instruction because the order of the selected arrangement number N of selected images cannot be shifted forward. Similarly, the instruction reception image display unit 61 does not display the scroll instruction reception image indicating the sending instruction in the superimposition area when the arrangement number of selection images displayed in the scroll area includes the selection image in the last order. This is because it is not necessary to accept a scroll operation indicating a feed instruction because the order of the selected number of selectable arrangement images cannot be shifted later.

  When the selectable number N of selectable images displayed in the scroll area includes the first selected image, the first selected image is displayed at the end of the scroll area. It may overlap with the overlap area. When the selectable number N of selectable images displayed in the scroll area includes the last selected image, the last selected image is displayed at the end of the scroll area. It may overlap with the overlap area.

  Here, a case will be described as an example where M selected images are associated with the operation screen, and the number of possible scroll areas included in the operation screen is N. However, M and N are positive integers, and M is N or more. Specifically, the instruction acceptance image display unit 61 is a scroll instruction that indicates a return instruction when the selection image display unit 63 displays N selectable images from the first to the Nth arrangement. The scroll instruction acceptance image indicating the sending instruction is displayed without displaying the acceptance image. When the Nth selection image overlaps with the superimposition region, the scroll instruction acceptance image indicating the feed instruction is displayed in a superimposition region overlapping with the Nth selection image. The instruction reception image display unit 61 indicates a return instruction when the selection image display unit 63 displays N selectable images from the Jth to the (J + N−1) th in the scroll area. A scroll instruction acceptance image is displayed and a scroll instruction acceptance image indicating a feed instruction is displayed. However, J is an integer of 2 or more (MN). When the J-th selection image overlaps with the superimposition region, the scroll instruction acceptance image indicating the feed instruction is displayed so as to overlap with the superimposition region overlapping with the J-th selection image. When the (J + N−1) th selected image overlaps with the superimposed area, the scroll instruction acceptance image indicating the feed instruction is displayed superimposed on the (J + N−1) th selected image. The instruction acceptance image display unit 61 accepts a scroll instruction indicating a return instruction when the selection image display unit 63 displays the (M−N + 1) th to Mth selectable number of selection images. Displays an image, but does not display a scroll instruction acceptance image indicating a feed instruction. When the (M−N + 1) th selected image overlaps the superimposition region, the scroll instruction acceptance image indicating the return instruction is displayed so as to be superimposed on the superimposition region overlapping the (M−N + 1) th selection image.

  The number-of-times display unit 69 receives the selected image identification information for each of the selectable number N of selected images from the selected image display unit 63, and displays the number of times the scroll operation can be accepted on the operation screen. The number-of-times display unit 69 can accept a scroll operation indicating a feed instruction from the order of the first selected image and the order of the last selected image, based on the selected image identification information of each of the N selectable images. And the number of times that a scroll operation indicating a return instruction can be accepted is determined. The number-of-times display unit 69 displays the number of times that a scroll operation indicating a feed instruction can be received in the vicinity of a superimposition area corresponding to a scroll instruction reception image to which a scroll operation indicating a feed instruction is assigned, and a scroll operation indicating a return instruction Is displayed in the vicinity of the superimposed area corresponding to the scroll instruction acceptance image to which the scroll operation indicating the return instruction is assigned. When the number display unit 69 determines “0” as the number of times that the scroll operation indicating the feed instruction can be accepted, the count display unit 69 can output a notification instruction corresponding to the feed instruction to the notification unit 71 and accept the scroll operation indicating the return instruction. When “0” is determined as the correct number of times, a notification instruction corresponding to the return instruction is output to the notification unit 71.

  The notification unit 71 notifies the user that the scroll operation cannot be accepted in response to the notification instruction input from the number display unit 69. Specifically, when a notification instruction corresponding to the return instruction is input from the number display unit 69, an image indicating that the scroll operation corresponding to the return instruction cannot be received is displayed on the operation screen. For example, it is displayed in the vicinity of the overlapping area corresponding to the reel instruction acceptance image for the return instruction. When a notification instruction corresponding to the feed instruction is input from the number display unit 69, an unacceptable notification image indicating that the scroll operation corresponding to the feed instruction cannot be received is displayed on the operation screen. For example, the image is displayed in the vicinity of the overlapping area corresponding to the scroll acceptance image indicating the feed instruction.

  Here, the operation screen will be described. Here, a case will be described as an example in which ten selected images in order from the first to the tenth are assigned to the operation screen. FIG. 5 is a first diagram illustrating an example of the operation screen. Referring to FIG. 5, operation screen 500 includes a scroll area 510. The scroll area 510 has a size capable of displaying five selected images. On the operation screen 500, the fourth to eighth selection images 524 to 528 are arranged in the scroll area 510. In FIG. 5, in order to indicate the order of the selected images 524 to 528, numerals indicating the respective orders are given.

  The scroll area 510 includes two overlapping areas 541A and 543A at both ends. In the superimposition area 541A, a scroll instruction acceptance image 541 indicating a return instruction is arranged, and a superposition area 543A and a scroll instruction acceptance image 543 indicating a feed instruction are arranged. The fourth selection image 524 with the earliest order overlaps the overlapping area 541A, and the scroll instruction receiving image 541 indicating the return instruction is the fourth selection in the portion overlapping the overlapping area 541A of the fourth selection image 524. It is displayed superimposed on the image 524. Since the eighth selected image 524 with the last order does not overlap with the overlapping area 543A, a scroll instruction acceptance image 541 indicating a return instruction is arranged on the right side of the eighth selected image 524 with the last order.

  In addition, the operation screen 500 has a receivable number display image below each of the superimposition area 541A corresponding to the scroll instruction reception image 541 indicating the return instruction and below the superposition area 543A corresponding to the scroll instruction reception image 543 indicating the feed instruction. 551,553. The acceptable number display image 551 represents the number of times “3” that can accept a scroll operation indicating a return instruction, and notifies the user that the number of times that a scroll operation indicating a return instruction can be input is “3”. Receivable count display image 553 represents the number of times “2” that can accept a scroll operation indicating a feed instruction, and notifies the user that the number of times that a scroll operation indicating a return instruction can be input is “2”.

  Returning to FIG. 4, the mode switching unit 51 switches the reception mode between the normal mode and the continuous mode based on the position on the display surface of the LCD 165 detected by the touch panel 169, and switches the reception mode to the instruction detection unit 53. Output. 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 continues the reception mode from the normal mode when the touch panel 169 continuously detects the position inside one of the two overlapping areas 541A and 543A for a predetermined number of times or more. Switch to mode. After switching the reception mode to the continuous mode, the mode switching unit 51 changes the reception mode from the continuous mode when the touch panel 169 does not continuously detect that the position in the overlapping areas 541A and 543A is instructed. 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 is configured so that the touch panel 169 detects that one of the two overlap areas 541A and 543A, for example, the position inside the overlap area 541A is detected before the touch panel 169 reaches a threshold value. When the position in the overlapping area 541A is detected, it is determined that the position in the overlapping area 541A has been continuously detected, and the reception mode is switched to the continuous mode. After the mode switching unit 51 switches the reception mode to the continuous mode, the touch panel 169 passes the time without detecting the position in the superposition area 541A after the last detection of the position in the superposition area 541A. When the threshold value is exceeded, the acceptance mode is switched to the normal mode. Further, when the touch panel 169 detects the position in the overlapping area 543A before the elapsed time after the touch panel 169 detects the position in the overlapping area 543A reaches the threshold value, the mode switching unit 51 detects the overlapping position. It is determined that the positions in the region 543A have been continuously detected, and the reception mode is switched to the continuous mode. After the mode switching unit 51 switches the reception mode to the continuous mode, the touch panel 169 passes the time without detecting the position in the overlapping area 543A after the last detection of the position in the overlapping area 543A. When the threshold value is exceeded, the acceptance mode is switched to the normal mode.

  The mode switching unit 51 outputs the reception mode to the instruction detection unit 53 and the operation support unit 67. Further, mode switching unit 51 outputs the threshold value input from threshold value determining unit 55 to operation support unit 67.

  The threshold value determination unit 55 determines a threshold value. For each user who operates MFP 100, an interval for continuously indicating the positions in superimposition areas 541A and 543A is stored, and threshold determination unit 55 determines a threshold based on the stored interval. To do. 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, the time required for the user to confirm the number N of selectable images displayed in the scroll area may be set.

  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. The instruction detection unit 53 is selected when the touch panel 169 detects a position other than the two overlapping areas 541A and 543A by the touch panel 169 regardless of whether the reception mode is the normal mode or the continuous mode. An image instruction operation is detected. The selected image instruction operation is an operation for specifying a selected image including a position detected by the touch panel 169 from among the N arrangementable selection images displayed in the scroll area by the selected image display unit 63. When the reception mode is the normal mode, the instruction detection unit 53 detects the position inside one of the two overlapping areas 541A and 543A using the touch panel 169, for example, detects the position inside the overlapping area 541A. In this case, if the scroll instruction acceptance image 541 is displayed in the superimposition area 541A, the scroll operation is detected. If the scroll instruction acceptance image 541 is not displayed in the superposition area 541A, the selection image instruction operation is detected. In addition, when the reception mode is the continuous mode, the instruction detection unit 53 detects, for example, a position in the superposition region 541A when the position inside one of the two superposition regions 541A and 543A is detected by the touch panel 169. If a scroll instruction acceptance image is displayed in the overlapping area 541A, the scroll operation is detected. If a position in the overlapping area 543A is detected, the scroll instruction acceptance image is displayed in the overlapping area 543A. The scroll operation is detected regardless of whether or not it is in.

  The instruction detection unit 53 outputs a selection instruction to the state switching unit 65 when detecting a selected image instruction operation. The selection instruction includes selection image identification information for identifying the selection image specified by the selection image instruction operation. The instruction detection unit 53 outputs the scroll operation to the selected image display unit 63 when detecting the scroll operation. The scroll operation includes a feed instruction and a return instruction. When the position in the superimposition area 543A corresponding to the scroll instruction reception image corresponding to the feed instruction is detected, the instruction detection unit 53 outputs a scroll operation indicating the feed instruction to the selected image display unit 63, and returns to the return instruction. When the position in the overlapping area 541A corresponding to the corresponding scroll instruction acceptance image is detected, a scroll operation indicating a return instruction is output to the selected image display unit 63.

  Specifically, at the stage where N selectable images from the first to the Nth are displayed, the instruction reception image display unit 61 causes the scroll instruction reception image 541 to be superimposed on the overlapping area 541A of the scroll area 510. Is not displayed, and the scroll instruction acceptance image 543 is displayed in the overlapping region 543A of the scroll region 510. The first selected image overlaps with the overlapping area 541A. In addition, the Nth selected image may overlap with the overlapping region 543A. When the reception mode is the normal mode, the instruction detection unit 53 detects the selection image instruction operation for specifying the first selection image when the touch panel 169 detects the position in the overlapping area 541A. Since the image 541 is not displayed, the scroll operation is not detected. In addition, when the reception mode is the continuous mode, the instruction detection unit 53 does not detect the selection image instruction operation for specifying the first selection image when the position in the overlapping region 541A is detected by the touch panel 169. Scroll operation is detected.

  Similarly, at the stage where N selectable images from the (M−N + 1) th to the Mth are displayed, the instruction reception image display unit 61 accepts a scroll instruction in the overlapping area 541A of the scroll area 510. The image 541 is displayed, and the scroll instruction acceptance image 543 is not displayed in the overlapping region 543A of the scroll region 510. The (M−N + 1) th selected image may overlap with the overlapping area 541A, and the Mth selected image overlaps with the overlapping area 543A. When the reception mode is the normal mode, the instruction detection unit 53 detects the selection image instruction operation for specifying the Mth selection image when the position in the overlapping area 543A is detected by the touch panel 169, but the scroll operation is performed. Do not detect. In addition, when the reception mode is the continuous mode, the instruction detection unit 53 does not detect the selection image instruction operation for specifying the Mth selection image when the touch panel 169 detects the position in the overlapping area 543A. Scroll operation is detected.

  The operation support unit 67 receives selection image identification information for identifying a selection image from the selection image display unit 63, and receives a reception mode from the mode switching unit 51. The operation support unit 67 selects the first or last selected image among the selected images specified by the selected image identification information input from the selected image display unit 63 while the reception mode is switched to the continuous mode. If included, the scroll instruction acceptance image is displayed in the overlapping areas 541A and 543. Specifically, the operation support unit 67 displays a scroll instruction acceptance image in the superimposition region 541A when the first selection image is included in the selection number N of arrangement images displayed by the selection image display unit 63. If the last selected image is included among the N arrangementable number of selected images displayed by the selected image display unit 63, the scroll instruction acceptance image is displayed in the overlapping area 543A. When displaying the scroll instruction acceptance image on the LCD 165, the operation support unit 67 outputs the position of the scroll instruction acceptance image on the display surface of the LCD 165 to the mode switching unit 51 and the instruction detection unit 53.

  In addition, the operation support unit 67 determines a predetermined time from the threshold value input from the mode switching unit 51. The predetermined time is a value larger than the threshold value. When the order of the selected images specified by the selected image identification information input from the selected image display unit 63 is the first or last while the reception mode is switched to the normal mode, the operation support unit 67, for example, the order In the first case, the scroll instruction acceptance image is displayed in the overlapping area 541A for a predetermined time, and when the predetermined time has elapsed after the scroll instruction acceptance image is displayed, the display of the scroll instruction acceptance image is terminated. If the order of the selected images specified by the selected image identification information input from the selected image display unit 63 is the last while the reception mode is switched to the normal mode, the operation support unit 67 scrolls to the overlapping region 543A. The instruction acceptance image is displayed for a predetermined time, and when the predetermined time has elapsed since the scroll instruction acceptance image is displayed, the display of the scroll instruction acceptance image is terminated.

  For example, when a scroll operation indicating a return instruction is detected in a state where the second selection image is displayed in the scroll area 510, the first selection image is displayed in the scroll area 510. The unit 67 displays the scroll instruction acceptance image 541 for a predetermined time in the overlapping area 541A. If superimposition area 541A is instructed before the time determined by the threshold value elapses after scroll instruction acceptance image 541 is displayed, mode acceptance unit 51 switches the acceptance mode to continuous mode. In this case, the operation support unit 67 displays the scroll instruction acceptance image 541 in the overlapping area 541A. For this reason, it is possible to notify the user of an operation for instructing the overlapping area 541A as a scroll operation.

  Further, when the order of the selected images specified by the selected image identification information input from the selected image display unit 63 is the first or last while the reception support mode is switched to the normal mode, the operation support unit 67, for example, When the order is the first, every time the position inside the overlapping area 541A is detected by the touch panel 169, the scroll instruction acceptance image is displayed in the overlapping area 541A for a predetermined time, and the scroll instruction acceptance image is displayed for a predetermined time. When elapses, the display of the scroll instruction acceptance image is terminated. Since the predetermined time is longer than the threshold value, the scroll instruction acceptance image 451 is displayed in the overlapping area 541A while the user continuously indicates the overlapping area 541A, and the user indicates the overlapping area 541A last. When the elapsed time after the time exceeds the threshold value, the reception mode is switched to the normal mode, but the scroll instruction reception image 451 is displayed in the superposition area 541A until a predetermined time has elapsed since the user last indicated the superposition area 541A. Remains displayed. Similarly, while the user is continuously instructing the overlapping area 543A, the scroll instruction acceptance image 543 is displayed in the overlapping area 543A, and the elapsed time since the user last specified the overlapping area 543A is a threshold value. Exceeds the normal mode, the scroll instruction acceptance image 452 remains displayed in the superposition area 543A until a predetermined time has elapsed since the user last designated the superposition area 543A.

  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. For example, the brightness of the selected image specified by the selected image identification information included in the selection instruction is set higher than that of other selected images. Further, the selected image specified by the selected image identification information included in the selection instruction is displayed in reverse, and the other selected images are left in the normal display without being displayed in reverse. In addition, when the selected image specified by the selected image identification information included in the selection instruction is associated with a command for displaying another window, the state switching unit 65 executes the command and relates to the selected image. Display the window to be used.

  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 counts the number of times that the touch panel 169 continuously detects the positions in the overlapping areas 541A and 543A as a condition for switching the reception mode from the normal mode to the continuous mode. Is preferably an even number of times. It is possible not to switch the state of the selected image at the stage of switching the reception mode to the continuous mode.

  FIG. 6 is a diagram illustrating an example of an operation screen when the reception mode is the continuous mode. An operation screen 500A shown in FIG. 6 is a screen that is displayed when a scroll instruction acceptance image 541 indicating a return instruction is continuously instructed three or more times by the user in the operation screen 500 shown in FIG. Referring to FIG. 6, operation screen 500A is different from operation screen 500 shown in FIG. 5 in that scroll area 510 is changed to scroll area 510A. On the operation screen 500A, the first to fifth selection images 521 to 525 are arranged in the scroll area 510A. The scroll area 510 includes two overlapping areas 541A and 543A at both ends. The overlapping area 541A overlaps with a part of the first selection image 521, and the scroll instruction acceptance image 541 is displayed superimposed on the first selection image 524. Superimposition area 543A is arranged on the right side of fifth selection image 525, and scroll instruction acceptance image 543 is displayed.

  In addition, operation screen 500A includes acceptable number display images 551 and 553 below superimposition area 541A and superimposition area 543A, respectively. The receivable count display image 551 indicates the number of times “0” that can accept a scroll operation indicating a return instruction, and notifies the user that the number of times that a scroll operation indicating a return instruction can be input is “0”. The receivable count display image 553 indicates the number of times “5” that can accept a scroll operation indicating a feed instruction, and notifies the user that the number of times that a scroll operation indicating a return instruction can be input is “5”.

  Furthermore, the operation screen 500A includes an unacceptable image 561 that is arranged so as to be superimposed on the first selection image 521 on the right side of the overlapping area 541A where the scroll instruction accepting image 541 indicating the return instruction is displayed. The unacceptable image 561 is a red rectangular image here. In the figure, red is indicated by hatching. The unacceptable image 561 is an image for notifying the user that a scroll operation indicating a return instruction cannot be accepted.

  Note that, here, the operation screen 500A shows an example in which the first to fifth selection images 521 to 525 are arranged in the scroll area 510A, but the order is the sixth in the scroll area 510A. When the tenth selected images 526 to 530 are arranged, the acceptable number display image 551 indicates the number of times “5” at which a scroll operation indicating a return instruction can be accepted, and the acceptable number display image 553. Represents the number of times that a scroll operation indicating a feed instruction can be accepted is “0”. Furthermore, operation screen 500A includes an unacceptable notification image that is arranged on the left side of superimposition area 543A on which scroll instruction acceptance image 543 indicating a feed instruction is displayed, superimposed on tenth selection image 530. In this case, the unacceptable notification image is an image for notifying the user that the scroll operation indicating the sending instruction cannot be accepted.

  FIG. 7 is a diagram illustrating an example of an operation screen when the reception mode is the normal mode. An operation screen 500B illustrated in FIG. 7 is a screen that is displayed after the scroll instruction reception image 541 indicating the return instruction is instructed three times by the user in the operation screen 500 illustrated in FIG. Referring to FIG. 7, operation screen 500B is different from operation screen 500 shown in FIG. 5 in that scroll area 510 is changed to scroll area 510B. The scroll area 510B includes two overlapping areas 541A and 543A at both ends. The overlapping area 541A overlaps a part of the first selected image 521. Superimposition area 543A is arranged on the right side of fifth selection image 525, and scroll instruction acceptance image 543 is displayed.

  The operation screen 500B does not include the scroll instruction reception image 541 indicating the return instruction that has been arranged in the scroll area 510 of the operation screen 500 shown in FIG. This is because it is not necessary to accept a scroll instruction indicating a return instruction because the first selected image 521 is displayed.

  FIG. 8 is a flowchart illustrating an example of the flow of instruction reception processing. The instruction 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. 8, 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 S14 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 instruction 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, a scroll area display process is executed, and the process returns to step S02. Although details of the scroll region display processing will be described later, this is processing for displaying the selected image and the scroll instruction acceptance image in the scroll region.

  In step S08, 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 S09. If not, the process proceeds to step S13. 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 S09, 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 S10). If the state of the selected image has been switched, the process proceeds to step S11. If not, the process proceeds to step S12. In step S12, the state of the selected image specified in step S09 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 S11, 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 S13, 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 is terminated; otherwise, the process proceeds to step S14. In step S14, 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. 9 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 the reception mode switching process in parallel with the instruction reception process described above. Referring to FIG. 9, 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 the user instructs the scroll instruction acceptance image, in other words, the number of scroll operations.

  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 overlapping region in the operation screen. It is determined whether or not the touch panel 169 has detected the position inside either the overlapping region 451A or the overlapping region 453A. If the position inside the overlapping area is detected by touch panel 169, the process proceeds to step S45. If not, 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 S48; otherwise, the process proceeds to step S47. The case where the value of the variable C is smaller than 2 is a case where the user designates the overlapping area 451A or the overlapping area 453A first. 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 one of the overlapping area 451A and the overlapping area 453A twice or more. In step S48, it is determined whether or not the value of timer T is equal to or less than threshold value TH1. If the value of timer T is equal to or smaller than threshold value TH1, the process proceeds to step S49. If not, the process proceeds to step S51. The threshold value TH1 is a predetermined value, and is the maximum value of the interval to be instructed when the user continuously indicates either the overlapping region 451A or the overlapping region 453A. For example, the interval at which the user continuously indicates the overlapping area 451A or the overlapping area 453A may be stored as a history, and the threshold value TH1 may be determined using the history. The maximum value of the interval stored as the history is preferable. Since different users have different intervals for continuously indicating the overlapping area 451A or the overlapping area 453A, a threshold corresponding to the user who operates the MFP 100 can be used.

  In step S49, the reception mode is switched to the continuous 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 not a superposition region, if it is determined in step S48 that the value of the timer T is greater than the threshold value Th1, Or it is a case where operation by a user is detected in step S53. When the value of the timer T is larger than the threshold value TH1, the interval from when the user designates the overlapping area 451A or the overlapping area 453A, for example, the overlapping area 451A, to the next indicating the overlapping area 451A is the threshold value. This is a case where it is greater than TH1, and in this case, it is not determined that the user has continuously indicated the overlapping area 451A. In addition, when the user designates a position different from the overlapping region 451A, or when the user performs an operation different from the operation that designates the touch panel 169, even if the timer T is equal to or less than the threshold value TH1, the user Is not determined to indicate the continuous area 451A.

  FIG. 10 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 instruction reception process and the reception mode switching process described above. For this reason, the reception mode is switched between the normal mode and the continuous mode by the CPU 111 executing the reception mode switching process. Referring to FIG. 10, 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 continuous mode, the process proceeds to step S30.

  In step S23, it is determined whether or not the position detected in step S21 is within the overlapping region in the operation screen. It is determined whether or not the touch panel 169 has detected the position inside either the overlapping region 451A or the overlapping region 453A. If the position in the overlapping area is detected by touch panel 169, the process proceeds to step S24. If not, the process proceeds to step S27. In step S24, it is determined whether or not a scroll instruction acceptance image is displayed in the overlapping area. If the scroll instruction acceptance image is displayed, the process proceeds to step S25. If not, the process proceeds to step S26. For example, when the position in the overlapping area 451A is detected by the touch panel 169, if the scroll instruction acceptance image 451 is displayed in the overlapping area 451A, the process proceeds to step S25; otherwise, the process proceeds to step S26. . When the position in superimposition area 453A is detected by touch panel 169, if scroll instruction acceptance image 453 is displayed in superposition area 453A, the process proceeds to step S31; otherwise, the process proceeds to step S32.

  In step S25, a scroll operation is detected, and the process returns to step S21. When the touch panel 169 detects a position in the overlapping area 451A, a scroll operation indicating a return instruction associated with the scroll instruction reception image 451 is detected. When the position in superimposition area 453A is detected by touch panel 169, a scroll operation indicating a feed instruction associated with scroll instruction reception image 453 is detected. In step S26, a selected image instruction operation for indicating a selected image including the position detected in step S21 is detected, and the process returns to step S21.

  In step S27, 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 S28; otherwise, the process proceeds to step S29. In step S28, a selected image instruction operation is detected, and the process returns to step S21. In step S29, other operations are detected, and the process returns to step S21. For example, the operation associated with the position detected in step S21 in the operation screen is detected. For example, if the position detected in step S21 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 S21 in the operation screen, the process directly returns to step S21.

  When the process proceeds to step S30, the reception mode is the continuous mode. In step S30, it is determined whether or not the position detected in step S21 is within the overlapping region in the operation screen. It is determined whether or not the touch panel 169 has detected the position inside either the overlapping region 451A or the overlapping region 453A. If the position in the overlapping area is detected by touch panel 169, the process proceeds to step S31. If not, the process proceeds to step S32.

  In step S31, a scroll operation associated with the scroll instruction acceptance image corresponding to the superimposed region including the position detected in step S21 is detected, and the process returns to step S21. When the position in the overlapping area 451A is detected by the touch panel 169, a scroll operation indicating a return instruction associated with the scroll instruction receiving image 451 corresponding to the overlapping area 451A is detected. When the position in the overlapping area 453A is detected by the touch panel 169, a scroll operation indicating a feed instruction associated with the scroll instruction receiving image 453 corresponding to the overlapping area 453A is detected.

  The processes in steps S32 to S34 are the same as the processes in steps S27 to S29, respectively. Therefore, the description will not be repeated here.

  FIG. 11 is a flowchart illustrating an example of the flow of scroll area display processing. The scroll area display process is a process executed in step S07 in FIG. 8, and the scroll direction is determined when step S07 is executed. When a scroll operation indicating a return instruction is detected, the scroll direction is the return direction. When a scroll operation indicating a feed instruction is detected, the scroll direction is the feed direction.

  Referring to FIG. 11, CPU 111 selects a selectable number N of selectable images including selected images in the order determined according to the scroll direction (step S <b> 61). Then, the selected N arrangementable images are displayed in the scroll area in the operation screen (step S62), and the process proceeds to step S63. 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 the scroll direction is the feed direction, select the selectable number of selectable images including the selectable image whose order is later than any of the selectable number N of selectable images selected when the scroll operation is detected, and scroll Arrange them side by side in the 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 the scroll direction is the return direction, the selectable number of selectable images including the selectable image whose order is earlier than any of the selectable number N of selectable images selected when the scroll operation is detected is selected. And arrange them 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 S63, it is determined whether or not the first rank of the selected arrangement number N of selected images is the first. If the first selected image is selected, the process proceeds to step S64. If not, the process proceeds to step S65.

  In step S64, an unacceptable image indicating that the scroll operation corresponding to the return instruction cannot be received is displayed in the vicinity of the overlapping area 451A corresponding to the scroll instruction received image indicating the return instruction, and the process proceeds to step S67. In step S65, the number of times that a scroll operation indicating a return instruction can be accepted from the order of the first selected image is determined. In the next step S66, the acceptable number is displayed in the vicinity of the overlapping area 451A, and the process proceeds to step S68. Note that step S65 and step S66 may be executed when the process proceeds to step S64. In this case, an unacceptable image is displayed and the acceptable number “0” is displayed.

  In step S67, it is determined whether the acceptance mode is the normal mode. If the acceptance mode is the normal mode, the process proceeds to step S69. If the acceptance mode is the continuous mode, the process proceeds to step S68. In step S68, scroll instruction acceptance image 451 is displayed in superimposition area 451A, and the process proceeds to step S69.

  In step S69, it is determined whether or not the last order of the selected arrangement number N of selected images is the last M-th order among all the selected images. If the Mth selected image has been selected, the process proceeds to step S70; otherwise, the process proceeds to step S71.

  In step S70, an unacceptable image indicating that the scroll operation corresponding to the feed instruction cannot be accepted is displayed in the vicinity of the overlapping region 453A, and the process proceeds to step S73. In step S71, the number of times that the scroll operation corresponding to the sending instruction can be accepted is determined from the order of the last selected image. In the next step S72, the acceptable number is displayed in the vicinity of the overlapping area 453A, and the process proceeds to step S74. Note that step S71 and step S72 may be executed when the process proceeds to step S70. In this case, an unacceptable image is displayed and the acceptable number “0” is displayed.

  In step S73, it is determined whether the acceptance mode is the normal mode. If the reception mode is the normal mode, the process returns to the instruction reception process. If the reception mode is the continuous mode, the process proceeds to step S74. In step S74, the scroll instruction acceptance image is displayed in the superimposed area of the last selected image, and the process returns to the instruction acceptance process. In step S74, scroll instruction acceptance image 453 is displayed in superimposition area 453A, and the process returns to the instruction acceptance process.

  As described above, MFP 100 according to the present embodiment functions as an electronic device, displays a number N of selectable images arranged in scroll area 510 and displays the first selected image 521 in scroll area 510. The scroll instruction acceptance image 541 is displayed in the superimposition area 541A of the scroll area 510, and the scroll instruction acceptance image 543 is displayed in the superposition area 543A on the condition that the selection image in the last order is not included. indicate. Then, the reception mode is switched from the normal mode to the continuous mode when the position inside the overlapping area 541A is continuously detected a predetermined number of times or more. Similarly, the reception mode is switched from the normal mode to the continuous mode when the position inside the overlapping region 543A is continuously detected a predetermined number of times or more. For example, when the position inside the overlapping area 541A is detected in the normal mode, if the scroll instruction receiving image 541 is displayed in the overlapping area 541A including the detected position, the scroll operation is detected and the scroll instruction receiving is detected. If the image 541 is not displayed, a selected image instruction operation for specifying a selected image including the detected position is detected, and when the position inside the superimposed region 541A is detected in the continuous mode, the detected position is The scroll operation is detected regardless of whether or not the scroll instruction acceptance image 541 is displayed in the overlapping region 541A. When the position inside the overlapping area 543A is detected in the normal mode, if the scroll instruction receiving image 543 is displayed in the overlapping area 543A including the detected position, the scroll operation is detected and the scroll instruction receiving image 543 is detected. If the selected image instruction operation for specifying the selected image including the detected position is detected and the position inside the overlapping region 543A is detected in the continuous mode state, the overlapping including the detected position is performed. Regardless of whether or not the scroll instruction acceptance image 543 is displayed in the region 543A, the scroll operation is detected. For this reason, when the user continuously instructs the scroll instruction acceptance image a predetermined number of times or more, the scroll operation is detected regardless of whether the scroll instruction acceptance image is displayed. In this case, when the scroll instruction acceptance image is no longer displayed in the superimposition area, the selection image instruction operation for instructing the selection image displayed in the superposition area is not detected. For this reason, it is possible to prevent an erroneous operation of the user who inputs the scroll operation.

  Further, when the reception mode is the continuous mode, MFP 100 includes a scroll instruction reception image when selection images of the first or last order among all the selection images are included in the selectable number N of selection images. Is displayed in the scroll area. For this reason, when the selection image in the first order is included in the continuous mode state, the scroll instruction acceptance image 541 is displayed in the overlapping area 541A of the scroll area 510, and the selection image in the last order is included. In this case, since the scroll instruction acceptance image 543 is displayed in the overlap area 543A of the scroll area 510, it is possible to notify the user that the operation for instructing the overlap area 541A or the overlap area 543A is a scroll operation.

  For example, on the operation screen 500 shown in FIG. 5, when the scroll instruction acceptance image 541 indicating a return instruction is instructed twice in succession by the user, the acceptance mode is switched from the normal mode to the continuous mode. When the scroll instruction acceptance image 541 indicating the return instruction is instructed three times in succession by the user, the operation screen 500A shown in FIG. 6 is displayed. Further, when the scroll instruction acceptance image 541 indicating the return instruction is instructed four or more times continuously by the user, the scroll operation is detected. For this reason, when the user instructs the scroll instruction acceptance image 541 continuously for a predetermined number of times or more, the scroll instruction image 541 continues to be displayed, so that the operation for instructing the overlapping area can be recognized as the scroll operation. Note that since the selected image in the first order is displayed in the scroll area, even if a scroll operation is detected, a set of selected images to be displayed in the scroll area is not selected.

  In the state where the reception mode is switched to the continuous mode, the MFP 100 switches the reception mode from the continuous mode to the normal mode when the position continuously detected by the touch panel 169 before switching to the continuous mode is not detected. . For this reason, the reception mode can be switched to the continuous mode only while the position in the overlapping region 541A or 542A is continuously detected.

  In addition, MFP 100 switches to continuous mode if the elapsed time from the last detection of a position in one of two overlapping areas 541A and 543A, for example, the position in overlapping area 541A, is within a threshold value, and overlapping area 541A When the elapsed time since the last position is detected exceeds a threshold value, the mode is switched to the normal mode. For this reason, it is possible to detect the operation of continuously instructing the overlapping areas 541A and 543A and the end of the operation of continuously instructing the overlapping area 541A.

  In addition, MFP 100 stores, as history information for each user, one of the two overlapping areas 541A and 543A, for example, an interval at which the position in overlapping area 541A is continuously detected, and sets a threshold based on the history information. Therefore, the interval of operations for continuously instructing the overlapping area 541A can be made different for each user.

  In addition, when the reception mode is the continuous mode and the first or last selected image is displayed in the scroll area, MFP 100 receives notification that the first or last selected image has been selected. Display disabled images. For this reason, it is possible to notify the user that the scroll operation cannot be input.

  In addition, MFP 100 displays acceptable number display images 551 and 553 indicating the number of times the scroll operation can be accepted before the first or last selected image is displayed in the scroll area in the state where the reception mode is the continuous mode. indicate. For this reason, it is possible to notify the user of the number of times the scroll operation is possible.

<Modification of scroll instruction acceptance image display>
In the MFP 100 described above, when the reception mode is switched to the continuous mode, when the first selection image or the Mth selection image among the M selection images is displayed in the scroll area, the operation support unit 67. Displays the scroll instruction acceptance image in the overlapping area 451A or the overlapping area 453A.

  When the first selected image among the M selected images is displayed in the scroll area 510, the MFP 100 in the modified example does not display the scroll instruction acceptance image in the overlapping area 451A. Further, MFP 100 in the modified example does not display the scroll instruction acceptance image in superimposition region 453A when the Mth selected image of M selection images is displayed in scroll region 510. In this case, the above-described operation support unit 67 is not necessary.

  Further, in MFP 100 according to the modified example, instruction detection unit 53, when the reception mode is the continuous mode, when touch panel 169 detects the position of one of two overlapping regions 541A and 543A, for example, overlapping region 541A If a scroll instruction acceptance image is displayed in the overlapping area 541A, a scroll operation is detected. If no scroll instruction acceptance image is displayed in the tatami area 541A, a scroll operation and a selected image instruction operation are detected. None of these are detected. Similarly, when the reception mode is the continuous mode, the instruction detection unit 53 detects a scroll operation if a scroll instruction reception image is displayed in the overlapping area 543A when the position in the overlapping area 543A is detected by the touch panel 169. If no scroll instruction acceptance image is displayed in the tatami area 543A, neither the scroll operation nor the selected image instruction operation is detected.

  For example, on the operation screen 500 shown in FIG. 5, when the scroll instruction acceptance image 541 indicating a return instruction is instructed twice in succession by the user, the acceptance mode is switched from the normal mode to the continuous mode. When the scroll instruction acceptance image 541 indicating the return instruction is instructed three times in succession by the user, the same operation screen as the operation screen 500B shown in FIG. 7 is displayed. In this case, the scroll instruction acceptance image 541 is not displayed in the superimposing area 541A, but when the superimposing area 541A is instructed four or more times continuously by the user, a scroll operation is detected. For this reason, when the user instructs the superimposition region 541A continuously for a predetermined number of times or more, here two or more times, the superimposition in which the scroll instruction acceptance image 541 is erroneously displayed after the scroll instruction image 541 is not displayed. Even when the area 541A is designated, since the selection image instruction operation for specifying the selection image 521 displayed in the overlapping area 541A is not detected, an operation for instructing the scroll instruction reception image 541 can be input.

<Modification of reception mode switching timing>
In MFP 100 in the above-described embodiment, mode switching unit 51 responds to the detection of the position inside the overlapping area before the first time has elapsed since the position inside the overlapping area was detected. When the reception mode is switched to the continuous mode and the reception mode is in the continuous mode and the first time has elapsed since the position inside the overlapped area has been detected, the mode is switched to the normal mode. The mode switching unit 61 in the modified example sets the reception mode to the continuous mode in response to the detection of the position inside the superposition area before the first time has elapsed since the position inside the superposition area was detected. If the second time longer than the first time elapses after the position inside the overlapping region is detected in the state where the switching and reception mode is the continuous mode, the mode is switched to the normal mode.

  The MFP 100 in the modification example switches to the continuous mode if the elapsed time from the last detection of one of the two overlapping areas 541A and 543A, for example, the position in the overlapping area 541A, is within the first time, and the overlapping is performed. When the elapsed time since the position in the area 541A was last detected exceeds a second time longer than the first time, the mode is switched to the normal mode. Since the interval between two consecutive operations that are the conditions for switching from continuous mode to normal mode is longer than the interval between two consecutive operations that are the conditions for switching to continuous mode, the continuous mode period is made as long as possible be able to.

  Further, MFP 100 in the modified example stores, as history information for each user, one of the two overlapping areas 541A and 543A, for example, an interval at which a position in overlapping area 541A is continuously detected, based on the history information. Since the first time is determined, the operation interval for continuously instructing the overlapping areas 541A and 543A can be varied for each user.

  In the embodiment described above, MFP 100 has been described as an example of an electronic device, but an operation reception method that causes MFP 100 to execute the processes illustrated in FIGS. 8 to 11 or CPU 111 that controls MFP 100 as the operation reception method. It goes without saying that the invention can be specified as an operation reception program for causing the program to be executed.
