FIGS. 5, 6 </ b> A, and 6 </ b> B are diagrams illustrating an example of the display screen of the display unit 410.

  When the main power supply of the multifunction device 1 is turned on by the operator, the display control unit 522 causes the display unit 410 to display an operation screen (initial screen A) as shown in FIG. 5 (S1). In the present embodiment, as an example of the initial screen A, the display control unit 522 causes the display unit 410 to display a display screen on which the operating conditions for the copy function can be set.

  When the display control unit 522 displays the initial screen A on the display unit 410, for example, when the density button 410 a is touched by the operator, the touch panel 4101 and the instruction receiving unit 523 make an instruction to set the copy density. Is received, the display control unit 522 causes the display unit 410 to display a density setting button 410b (part of the density setting screen) as shown in FIG.

  When the display control unit 522 displays the density setting button 410b, the operator touches any one of the buttons 410b1 to 410b5 constituting the density setting button 410b, and the touch panel 4101 causes the buttons 410b1 to 410b5 to be displayed.

That is, when the operator stops his finger at the coordinate position of any of the display positions of the buttons 410b1 to 410b5, it corresponds to the instruction receiving image (any of the buttons 410b1 to 410b5) displayed at the coordinate position. The instruction to be received is received by the instruction receiving unit 523 (S13).

  On the other hand, if a further coordinate position is received by the touch panel 4101 while the time measured by the instruction receiving unit 523 does not reach the predetermined elapsed time (NO in S3) in S3 (YES in S4). The speed detector 524 detects the change speed based on the coordinate positions before and after the change (S5).

  Here, the instruction receiving unit 523 displays the buttons (buttons 410b1 to 410b5) displayed at the display positions indicated by the coordinate positions received by the touch panel 4101 in S4 according to the change speed detected by the speed detecting unit 524 in S5. (Hereinafter referred to as “enlarge button”), the area for receiving the input of the instruction is expanded (S6).

  For example, as shown in FIG. 6B, the instruction receiving unit 523 changes the designation of the coordinate position as indicated by the operator in the direction of the arrow, and is displayed at the display position indicated by the coordinate position received in S4. If the button being operated is the button 410b3, the instruction input receiving area for receiving the input of the instruction associated with the button 410b3 is expanded to the display area of the button 410b4 adjacent to the arrow direction side.

  The area of the instruction input reception area to be enlarged is changed by the instruction reception unit 523 according to the change speed detected by the speed detection unit 524 in S5. For example, the change speed detected by the speed detection unit 524 in S5 reaches a predetermined speed (for example, the speed V = dx / dt = 4 in the above-described example, but this is not intended to limit the speed). If the change speed detected by the speed detector 524 in S5 is less than the predetermined speed, the area for expanding the instruction input reception area is increased as the change speed is higher. The instruction receiving unit 523 preferably performs processing such as preventing the instruction input receiving area from being enlarged.

  The instruction receiving unit 523 measures the elapsed time from the time of the enlargement process of the instruction input area of the button (S7). Even if the time measured by the instruction receiving unit 523 reaches a predetermined elapsed time (for example, 0.5 seconds), the designation of the next coordinate position cannot be received by the touch panel 4101 (YES in S7), that is, the operation When the person stops the finger at the coordinate position received by the touch panel 4101 in S4, an instruction corresponding to the button displayed at the coordinate position is received by the instruction receiving unit 523 (S13).

  On the other hand, if the designation of the next coordinate position is accepted by the touch panel 4101 (YES in S8) before the time measured by the instruction accepting unit 523 reaches the predetermined elapsed time (NO in S7), the instruction The accepting unit 523 measures an elapsed time from when the designation of the coordinate position is accepted (S9).

  If the touch panel 4101 does not accept the designation of the next coordinate position even if the time measured by the instruction accepting unit 523 reaches a predetermined elapsed time (for example, 0.5 seconds) (in S9). YES), the instruction receiving unit 523 determines whether the coordinate position designated in S8 is a coordinate position within the enlarged instruction input area (S10).

  If the instruction receiving unit 523 determines that the coordinate position specified in S8 is not within the range of the enlarged instruction input area (NO in S10), the instruction receiving unit 523 originally sets the coordinate position specified in S8. An instruction corresponding to the displayed button is received by the instruction receiving unit 523 (S13).

  When the instruction receiving unit 523 determines that the coordinate position specified in S8 is a coordinate position within the range of the enlarged instruction input area (YES in S10), the instruction receiving unit 523 displays the instruction associated with the enlarge button. An input is accepted (S11). That is, when the instruction input area for receiving an instruction corresponding to the enlarge button is enlarged as described above, the instruction accepting unit 523 is configured to display the original button (the enlarge button described above) displayed in the enlarged instruction input area. The input of the instruction associated with (not) is not accepted during the predetermined period.

  For example, as illustrated in FIG. 6B, the instruction receiving unit 523 expands the instruction input receiving area that receives an instruction input associated with the button 410 b 3 to the display area of the button 410 b 4. In the instruction input reception area 410b3, the input of the instruction associated with the button 410b4 is not received during the predetermined period.

  In S9, if the touch panel 4101 receives designation of the next coordinate position before the time measured by the instruction accepting unit 523 reaches the predetermined elapsed time (NO in S9) ( The process returns to S5, and the processes after S5 are performed again. If designation of a further next coordinate position is not accepted by the touch panel 4101 (NO in S12), the process returns to S9.

  Note that, in the above, the button displayed on the display position indicated by the coordinate position received by the touch panel 4101 in S4 is set to a size corresponding to the change speed detected by the speed detection unit 524 in S5. When the area for receiving the input of the associated instruction is enlarged (S6), even if the time measured by the instruction receiving unit 523 reaches a predetermined elapsed time, designation of the next coordinate position is received by the touch panel 4101. If not (YES in S7), that is, if the operator stops his finger at the coordinate position received on the touch panel 4101 in S4, an instruction corresponding to the button displayed at the coordinate position is accepted. The instruction receiving unit 523 receives the change detected by the speed detecting unit 524 so as to be received by the unit 523 (S13). The area for accepting the input of the instruction associated with the button displayed at the designated coordinate position is enlarged to a size corresponding to the degree for a predetermined period, but the instruction accepting unit 523 You may make it change a predetermined period according to the change speed detected by the speed detection part 524 in this way. For example, the instruction receiving unit 523 sets the change speed detected by the speed detection unit 524 in S5 to a predetermined speed (for example, the speed V = dx / dt = 4 in the above-described example. However, the speed is limited. When the change rate is faster, the predetermined period may be lengthened as the change rate increases.

  Next, a second embodiment of the display control process of the display unit 410 by the multifunction device 1 will be described. FIG. 7 is a flowchart illustrating a second embodiment of the display control process of the display unit 410 by the multifunction device 1. FIGS. 8A, 8 </ b> B, 9 </ b> C, and 9 </ b> A and 9 </ b> B are diagrams illustrating examples of the display screen of the display unit 410. Note that the description of the same processing as that of the first embodiment described above will be omitted.

  In the second embodiment, the instruction receiving unit 523 displays a button (in a display position indicated by the coordinate position received by the touch panel 4101 in S24 according to the change speed detected by the speed detecting unit 524 in S25 ( When enlarging the area for receiving the input of the instruction associated with the enlargement button) (S26), the display control unit 522 causes the touch panel 4101 to display the entire area of the enlarged instruction input area in S24. An image of the button (enlarged button) displayed at the display position indicated by the received coordinate position is displayed (S27).

  For example, as shown in FIG. 8B, the operator changes the designation of the coordinate position as shown in the arrow direction, and the button displayed at the display position indicated by the coordinate position accepted in S24 is a button. In the case of 410b3, when the instruction input receiving area for receiving the instruction input associated with the button 410b3 is expanded by the instruction receiving unit 523 to the display area of the button 410b4 adjacent to the arrow direction side. The display control unit 522 displays the image of the button 410b3 instead of the image of the button 410b4 in the instruction input reception area of the button 410b3 that is enlarged to the display area of the button 410b4.

  As shown in FIG. 8C, for example, the operator changes the designation of the coordinate position as shown in the arrow direction, and is displayed at the display position indicated by the coordinate position accepted in S24. Is the button 410b3, the expansion of the instruction input area by the instruction receiving unit 523 is not limited to the arrow direction in which the operator changes the designation of the coordinate position, but in the vertical direction or the diagonal direction in FIG. You may go. Also in this case, the display control unit 522 displays the image of the button 410b3 over the entire instruction input reception area to be enlarged, and the button 410b4 for the instruction input reception area of the button 410b3 to be enlarged in the display area of the button 410b4. Instead of this image, the image of the button 410b3 is displayed.

  The display processing in S27 by the display control unit 522 makes it easier for the operator to visually recognize the desired instruction receiving image that the user wants to designate (the button 410b3 in the examples of FIGS. 8B and 8C). It is possible to accurately input an instruction associated with the instruction receiving image.

  When the display control unit 522 performs the display process of S27 and displays the image of the button 410b3 over the entire instruction input reception area to be enlarged as shown in FIGS. 8B and 8C, for example, As shown in FIGS. 9 (a) and 9 (b), in the instruction input reception area enlarged in the display area of the button 410b4, the image of the button 410b3 is displayed with respect to the image of the button 410b3 while the image of the button 410b3 is displayed. You may make it display an image transparently.

  Next, a third embodiment of the display control process of the display unit 410 by the multifunction machine 1 will be described. FIG. 10 is a flowchart illustrating a third embodiment of the display control process of the display unit 410 by the multifunction machine 1. FIGS. 11A and 11B are diagrams illustrating an example of the display screen of the display unit 410.

  The third embodiment is a display process in the case where the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image.

  When the main power supply of the multifunction device 1 is turned on by the operator, the display control unit 522 displays the operation screen (initial screen A) as shown in FIG. 5 on the display unit 410 (S41). When the display control unit 522 displays the initial screen A on the display unit 410, for example, when the density button 410 a is touched by the operator, the touch panel 4101 and the instruction receiving unit 523 make an instruction to set the copy density. Is received, the display control unit 522 causes the display unit 410 to display a density setting button 410b (part of the density setting screen) as shown in FIG.

  When the display control unit 522 displays the density setting button 410b, the operator touches any one of the buttons 410b1 to 410b5 constituting the density setting button 410b, and the touch panel 4101 causes the buttons 410b1 to 410b5 to be displayed. When designation of the coordinate position of any display position is accepted (YES in S42), the instruction accepting unit 523 acquires information on the designated coordinate position from the touch panel 4101, and the instruction accepting unit 523 has a built-in timer. Is used to measure the elapsed time since the coordinate position was designated (S43). If the designation of the coordinate position of any of the buttons 410b1 to 410b5 is not accepted by the touch panel 4101 (NO in S42), the process of S41 is repeated.

  Here, even when the time measured by the instruction receiving unit 523 reaches a predetermined elapsed time (for example, 0.5 seconds), the touch panel 4101 cannot accept the designation of the next coordinate position (YES in S43). That is, when the operator stops his finger at the coordinate position of any of the display positions of the buttons 410b1 to 410b5, it corresponds to the instruction receiving image (any of the buttons 410b1 to 410b5) displayed at the coordinate position. The instruction to be received is received by the instruction receiving unit 523 (S43).

  On the other hand, in S43, when the time measured by the instruction receiving unit 523 does not reach the predetermined elapsed time (NO in S43), if a further coordinate position is received by the touch panel 4101 (YES in S44). The speed detection unit 524 detects the change direction based on the coordinate positions before and after the change (S45). Furthermore, the speed detector 524 detects the change speed based on the coordinate positions before and after the change (S46).

  Then, the display control unit 522 displays a display form of at least one instruction reception image among the plurality of instruction reception images to be scrolled according to the change speed detected by the speed detection unit 524 in S46. Are set differently from other instruction receiving images (S47). Various display forms such as the size of the image, the brightness of the image, and the color of the image can be adopted as the display form different from the other instruction receiving images.

  For example, as shown in FIG. 11A, the display control unit 522 displays a plurality of buttons 410b1 to 410b9 on the display unit 410 (in FIG. 11A, five buttons among the plurality of buttons 410b1 to 410b9 are simultaneously displayed. 11 shows an example displayed on the display unit 410. In FIG. 11A, when buttons 410b6 to 410b9 are not displayed in parallel and are scroll-displayed, the five buttons simultaneously displayed in parallel are displayed. As shown in FIG. 11B, the image of each button is set so as to be greatly scrolled as it approaches the center of the arrangement direction, and at least in the maximum display in FIG. The size of the button 410b1 is enlarged according to the change speed detected by the speed detection unit 524 in S46 (for example, the speed detection is performed in S46. Change speed detected is set fast enough to increase the magnification) by Part 524. However, the display control unit 522 detects the change speed detected by the speed detection unit 524 in S46 with respect to all the five buttons displayed in parallel at the same time, or arbitrarily extracted buttons of the five buttons displayed in parallel at the same time. You may set to the magnitude | size expanded according to.

  The display control unit 522 uses the display form set in this manner to display a plurality of instruction receiving images (buttons 410b1 to 410b9) to be displayed in the change direction detected by the speed detection unit 524 in S45. Then, scroll display is performed on the display unit 410 (S48). For example, as illustrated in FIG. 11B, when the change direction detected by the speed detection unit 524 in S45 is an arrow direction, the display control unit 522 displays each image of the buttons 410b1 to 410b9 in the direction of the arrow. Are displayed on the display unit 410 in increments of 5 so that each image is displayed.

  Next, a fourth embodiment of the display control process of the display unit 410 by the multifunction machine 1 will be described. FIG. 12 is a flowchart illustrating a fourth embodiment of the display control process of the display unit 410 by the multifunction machine 1. FIGS. 13A, 13 </ b> B, and 13 </ b> C are diagrams illustrating an example of a display screen of the display unit 410. Similarly to the third embodiment, the fourth embodiment is a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that the description of the same processing as that of the third embodiment described above will be omitted.

  In the fourth embodiment, the display control unit 522 receives at least one instruction from the plurality of instruction receiving images to be scrolled according to the change speed detected by the speed detection unit 524 in S56. The number of instruction receiving images to be displayed on the display unit 410 in accordance with the change speed detected by the speed detecting unit 524 in S56 as processing for setting the display form of the image to be different from other instruction receiving images A process for reducing the value is adopted (S57).

  For example, as illustrated in FIG. 13A, the display control unit 522 causes the display unit 410 to scroll and display five of the plurality of buttons 410b1 to 410b9 in parallel (in FIG. 13A, Buttons 410b6 to 410b9 are not displayed), and when the change speed detected by the speed detector 524 in S56 reaches a predetermined speed S1 that is faster than the predetermined standard speed S, it is shown in FIG. 13 (b). As described above, the number of buttons to be displayed in parallel on the display unit 410 is reduced to, for example, three. Furthermore, when the change speed detected by the speed detection unit 524 in S56 reaches a predetermined speed S2 that is faster than the speed S1, the display control unit 522 displays the display as shown in FIG. The number of buttons simultaneously displayed in parallel on the unit 410 is reduced to, for example, two, which is even smaller than the case of the speed S1. In these cases, it is preferable that the display control unit 522 displays the display area of the button image to be displayed as large as possible in the parallel display area.

  Even when scroll display is performed relatively quickly by the display control by the display control unit 522, an operation for scroll display can be performed by displaying a large instruction receiving image in a parallel display area that is a limited area. It is possible to improve the visibility of each instruction reception image by a person.

  Next, a fifth embodiment of the display control process of the display unit 410 by the multifunction machine 1 will be described. FIG. 14 is a flowchart illustrating a fifth embodiment of the display control process of the display unit 410 by the multifunction machine 1. FIGS. 15A, 15B, 16A, and 16B are diagrams showing examples of the display screen of the display unit 410. FIG. Similarly to the third and fourth embodiments, the fifth embodiment is a display process in the case where the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that the description of the same processing as in the third or fourth embodiment described above will be omitted.

  In the fifth embodiment, the display control unit 522 receives at least one instruction from among the plurality of instruction receiving images to be scrolled according to the change speed detected by the speed detection unit 524 in S66. As a process of setting the display form of the image to be different from other instruction receiving images, each of the plurality of instruction receiving images to be displayed in parallel is displayed according to the change speed detected by the speed detecting unit 524 in S66. While maintaining the size of the instruction receiving image, a process of setting a larger character (number, character, symbol, etc.) in each instruction receiving image is adopted as it approaches the center in the arrangement direction (S67). . At this time, the display control unit 522 enlarges at least the character in the instruction receiving image at the central portion to be displayed in the maximum size according to the change speed detected by the speed detection unit 524 in S66.

  For example, as illustrated in FIG. 15A, the display control unit 522 causes the display unit 410 to scroll and display five of the plurality of buttons 410b1 to 410b9 in the arrow direction (FIG. 15A). ), The buttons 410b6 to 410b9 are not displayed.) As shown in FIG. 15B, the buttons 410b6 to 410b9 are displayed in the image of each button as they approach the center in the arrangement direction while maintaining the size of each button. A process of setting a large character (number, character, symbol, etc.) is adopted (S67).

  By the display control by the display control unit 522, the operator can improve the visibility of the character indicated by the instruction receiving image at the center to be displayed at the maximum even when the change speed is increased, for example. It becomes easy to specify a desired instruction receiving image.

  Further, when the display control unit 522 enlarges the character in each button image according to the change speed detected by the speed detection unit 524 in S66, the display control unit 522 This character may be enlarged after being converted into an abbreviation with a reduced number of characters. For example, as shown in FIG. 16A, five of the plurality of buttons 410b1 to 410b9 are scrolled in parallel, the character in the button 410b1 is “Kyoto Ichiro”, and the character in the button 410b2 is “Osaka” In the case where “Jiro”, the character in the button 410b3 is “Saburo Kobe”, the character in the button 410b4 is “Shiro Nara”, and the character in the button 410b5 is “Shiro Shiga”, the display control unit 522 displays the speed detection unit in S66. When the change speed detected by 524 reaches a predetermined speed S1 higher than a predetermined standard speed S, for example, as shown in FIG. The character in is “KI”, the character in button 410b2 is “OG”, the character in button 410b3 is “KS” , Characters "NS" in button 410B4, characters in the button 410b5 is like "SG", after the abbreviation of reduced number of characters than the original character may perform the enlarged display.

  According to the display control, the character can be further enlarged and displayed in the instruction receiving image by reducing the number of display characters, and the operator can more easily specify a desired instruction receiving image. .

  Next, a sixth embodiment of display control processing of the display unit 410 by the multifunction machine 1 will be described. FIG. 17 is a flowchart illustrating a sixth embodiment of the display control process of the display unit 410 by the multifunction machine 1. 18A, 18B, and 18C are diagrams showing examples of the display screen of the display unit 410. FIG. The sixth embodiment is also a display process in the case where the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image.

  For example, as illustrated in FIG. 18A, in the multi function device 1, the display control unit 522 displays an operation screen B that displays a list image L indicating a transmission destination list of scan data read by the scanner unit 11. (S71), when the operator touches the scroll button SR1 or SR2 that forms part of the list image L, the touch display 4101 and the instruction receiving unit 523 receive a scroll display instruction (YES in S72). . If the scroll display instruction is not accepted by touch panel 4101 and instruction accepting unit 523 (NO in S72), the process of S71 is repeated. Further, the direction of the scroll display is, for example, the direction from the bottom to the top in FIG. 18A (hereinafter, the same applies to the embodiment in which the scroll display instruction is performed using the scroll buttons SR1 or SR2).

  At this time, for example, the speed detection unit 524 calculates the speed at which the destination images L1 to Ln constituting the list image L are scrolled according to the length of time that the scroll button SR1 or SR2 is touched by the operator. (S73). For example, the speed detection unit 524 increases the speed at which the destination images L1 to Ln are scrolled as the time for which the scroll button SR1 or SR2 is touched by the operator is longer, and the scroll button SR1 or SR2 is touched by the operator. The shorter the time is, the slower the scrolling speed of each of the destination images L1 to Ln.

  As shown in FIG. 18A, each of the transmission destination images L1 to Ln has a plurality of items each associated with a hierarchy. In the present embodiment, each of the transmission destination images L1 to Ln has items of “affiliation department”, “affiliation section”, “affiliation staff”, and “name” in this order from the upper layer. That is, each of the transmission destination images L1 to Ln is composed of four items of “affiliation department”, “affiliation section”, “affiliation staff”, and “name”.

  Here, the display control unit 522 decreases the number of items for each image scroll-displayed on the display unit 410 as the change speed detected by the speed detection unit 524 in S73 increases, and the change speed decreases. As it increases, the number of items for each image to be scroll-displayed on the display unit 410 is calculated (S74).

  For example, as shown in FIG. 18A, the display control unit 522 scrolls the display unit 410 with four of the plurality of destination images L1 to Ln arranged in parallel in the vertical direction in FIG. In the case of display (in FIG. 18A, except for the destination images L1 to L4 are not displayed), the scroll display speed detected by the speed detection unit 524 in S73 is determined in advance higher than the predetermined standard speed S. When the speed S1 is reached, for example, as shown in FIG. 18B, the number of display items for each destination image displayed on the display unit 410 is reduced to three. The items up to “Affiliation Division” and “Affiliation” are displayed items for each destination image. Further, when the scroll display speed detected by the speed detection unit 524 in S73 reaches a predetermined speed S2 that is faster than the speed S1, the display control unit 522 The number of display items for each destination image to be displayed on the display unit 410 is reduced to, for example, two, which is smaller than the case of the speed S1, and for each destination image from the upper hierarchy to “affiliation department” and “affiliation section”. Display items.

  When the display control unit 522 determines in S74 that the scroll display speed detected by the speed detection unit 524 in S73 has reached the speed E faster than the speed S1 and the speed S2, FIG. As shown in FIG. 4, scroll display may be performed in a state where only the items of the highest hierarchy are displayed for each of the destination images L1 to Ln that are targets of scroll display. Furthermore, the speed E is not related to the speed S1 and the speed S2 (that is, display control based on the speed S1 and the speed S2 is not performed), and the display control unit 522 is detected by the speed detection unit 524 in S73. When the scroll display speed reaches a predetermined speed E that is faster than a predetermined standard speed S, in S74, for example, the highest hierarchy for each of the transmission destination images L1 to Ln to be scrolled. Scroll display may be performed in a state where only the item is displayed.

  As a result, when the image is scrolled and displayed at a high change speed that reduces the image visibility of the operator, information about each image that the operator visually recognizes is reduced by reducing the number of items of each image. The amount is reduced, and the operator can easily grasp the contents of each image even during high-speed scroll display. In addition, when the image is scrolled and displayed at a low change speed that is considered not to reduce the image visibility of the operator, the number of items of each image is increased, so information about each image that the operator visually recognizes The operator can fully grasp the contents of each image without reducing the amount.

  Next, a seventh embodiment of the display control process of the display unit 410 by the multifunction machine 1 will be described. FIG. 19 is a flowchart illustrating a seventh embodiment of the display control process of the display unit 410 by the multifunction machine 1. 20A, 20B, and 20C are diagrams showing examples of the display screen of the display unit 410. FIG. The seventh embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the sixth embodiment is omitted.

  In the seventh embodiment, the display control unit 522 scrolls and displays the transmission destination images L1 to Ln on the display unit 410 such that the items having a high degree of matching between the transmission destination images are consecutive.

  Then, when the speed detection unit 524 calculates the speed at which the destination images L1 to Ln constituting the list image L are scrolled according to the length of time that the scroll button SR1 or SR2 is touched by the operator (S83). The display control unit 522 determines whether or not the change speed detected by the speed detection unit 524 in S83 has reached a predetermined first speed A (S84).

  When the display control unit 522 determines that the change speed detected by the speed detection unit 524 in S83 does not reach the first speed A (YES in S84), as shown in FIG. In a state where all items are displayed for each of the transmission destination images L1 to Ln, the transmission destination images L1 to Ln are scroll-displayed (S89).

  On the other hand, the display controller 522 has a second speed at which the change speed detected by the speed detector 524 in S83 has reached the first speed A and is faster than the first speed A. If it is determined that B has not been reached (NO in S84, YES in S85), the display control unit 522 is an item for each of the transmission destination images L1 to Ln to be scroll-displayed on the display unit 410, and is adjacently displayed. The items that match among the destination images to be displayed are displayed in a scrolling manner (S86). For example, when the transmission destination images are displayed as shown in FIG. 20A, the display control unit 522 matches the transmission destination images displayed adjacent to each other as shown in FIG. 20B. The item is hidden.

  On the other hand, when the display control unit 522 determines that the change speed detected by the speed detection unit 524 in S83 has reached the second speed B (NO in S84, NO in S85), the display control unit In step S90, a predetermined number of images are extracted from the transmission destination images having the same items in the highest hierarchy. For example, as illustrated in FIG. 20C, the display control unit 522 displays only the transmission destination image with the fastest display order among the transmission destination images having the same items in the highest hierarchy.

  Thus, in the present embodiment, the display control unit 522 determines that the change speed detected by the speed detection unit 524 in S83 has reached the second speed B that is faster than the first speed A. In this case (NO in S84, NO in S85), that is, the process of S90 is performed after the process of S86 is performed, but the process of S90 may be performed instead of the process of S86. That is, the second speed B serving as a reference for performing the process of S90 is not related to the first speed A, and the display control unit 522 determines that the change speed detected by the speed detection unit 524 is the second speed B. When it is determined that the number of images has reached, a process may be performed in which a predetermined number of images are extracted and displayed from the transmission destination images having the same items in the highest hierarchy.

  Thereby, the difference part between each transmission destination image required for the operator to identify the difference between each image is extracted and displayed on the display unit 410. Thereby, even when each of the transmission destination images is scroll-displayed at a high speed, the operator can easily identify the difference between the images displayed on the display unit 410.

  Next, a modified example of the seventh embodiment of the display control process of the display unit 410 by the multifunction device 1 will be described. FIG. 33 is a flowchart illustrating a modified example of the seventh embodiment of the display control process of the display unit 410 by the multifunction machine 1. 34A, 34B, 34C, and 34D are diagrams showing examples of the display screen of the display unit 410. FIG. The description of the same processing as that of the seventh embodiment using FIGS. 19 and 20 is omitted.

  Even in the modification example, the display control unit 522 scrolls and displays the transmission destination images L1 to Ln on the display unit 410 by continuously displaying the transmission images having a high degree of matching between the items. When the display control unit 522 determines that the change speed detected by the speed detection unit 524 has reached the second speed B (NO in S184, “Second speed B ≦ scroll display speed <first speed” in S185). Note that the third speed C is a predetermined speed that is higher than the second speed B), and the adjacent images having different upper layers are images of the different upper layers. Is displayed in the item of the currently displayed image and scroll display is performed (S191).

  For example, the display control unit 522 performs display as shown in FIG. In this variation, the number of destination images displayed on the display unit 410 at a time is five. However, this does not mean that the number of destination images displayed on the display unit 410 at a time is limited to five. That is, the change speed detected by the speed detection unit 524 satisfies the first speed A ≦ the scroll display speed <the second speed B. As shown in FIG. 34B, the display control unit 522 From the state where the items for each of the destination images L1 to Ln to be scroll-displayed on the display unit 410 and matching the destination images that are adjacently displayed are not displayed (S186). When the change speed detected by the speed detection unit 524 further increases and reaches the second speed B, the display control unit 522 displays the transmission destination image displayed first as shown in FIG. For destination images L3 to L5 in which the images of the upper layer items are different from L1 and L2, the “name” item that is the lower layer and the “affiliation” item that is one layer higher than that Display images of . In this case, the display control unit 522 preferably displays an image only on the item “name”. This is because the scroll display speed is increased, and thus the image visibility of the user is improved by reducing display items.

  Further, the change speed detected by the speed detection unit 524 reaches a predetermined third speed C that is faster than the second speed B, and the display control unit 522 determines that the detected change speed is the third speed C. When it is determined that the speed C has been reached (NO in S184, “Scroll speed ≧ third speed C” in S185), the display control unit 522 displays the adjacent image that is displayed following the previously displayed image. As for the image to be displayed, if the higher layer is different, the different higher layer image is displayed in the item of the currently displayed image and scrolled (S190).

  For example, as shown in FIG. 34D, the case where the transmission destination image L4 is displayed first will be described. The display control unit 522 performs the process of S19 on the transmission destination image L4 displayed first. For the image of the “affiliation section” item at a higher level than the image of the “affiliation section” item that has been determined to be the same for display processing, the image of the transmission destination image L4 displayed earlier The identity of the subsequent destination images L5... Is judged, and for the destination images L5 to L8 in which the images of the “affiliation section” item in the higher hierarchy are different, the “affiliation section” items in the different higher hierarchy are different. Is displayed in the “name” item currently displayed, and scroll display is performed. Also in this case, the display control unit 522 preferably displays an image only on the item “name”. This is because the scroll display speed is increased, and thus the image visibility of the user is improved by reducing display items. In FIG. 34 (d), for the transmission destination images L5 to L8, the items of “affiliation department”, “affiliation section”, and “affiliation staff” are indicated by broken lines, but this is the higher order of the transmission destination images L5 to L8. It is shown for explaining the image content of the hierarchy, and does not show a preferable display form.

  Next, an eighth embodiment of display control processing of the display unit 410 by the multifunction machine 1 will be described. FIG. 21 is a flowchart illustrating an eighth embodiment of display control processing of the display unit 410 by the multifunction machine 1. FIGS. 22A and 22B are diagrams showing an example of the display screen of the display unit 410. The eighth embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the sixth or seventh embodiment is omitted.

  In the eighth embodiment, the display control unit 522 scrolls and displays the transmission destination images L1 to Ln in order on the display unit 410 in a sequence of items with a high degree of matching between the transmission destination images. In the eighth embodiment, the number of destination images displayed on the display unit 410 at a time is four. However, this is not intended to limit the number of destination images displayed on the display unit 410 at a time to four.

  For example, in the multifunction device 1, when the display control unit 522 displays the operation screen B displaying the list image L indicating the transmission data list of the scan data read by the scanner unit 11 on the display unit 410 (S101). When the operator touches the scroll button SR1 or SR2, and thereby the scroll display instruction is received by the touch panel 4101 and the instruction receiving unit 523 (YES in S102), the display control unit 522 displays the transmission destination images L1 to Ln. The scroll display is started (S103). When the scroll display instruction is not received by the touch panel 4101 and the instruction receiving unit 523 (NO in S102), the process of S101 is repeated.

  Here, when an instruction to stop the scroll display is received by the touch panel 4101 and the stop instruction receiving unit 525 by an operation such as interrupting the touch on the scroll button SR1 or SR2 (YES in S104), the display control unit 522 is a predetermined number of images from the instruction receiving image (any one of the transmission destination images L1 to Ln) scroll-displayed on the display unit 410 when the scroll display stop instruction is received. The display unit 410 displays the transmission destination image displayed previously (S106).

  For example, as shown in FIG. 22A, the display control unit 522 performs scroll display, and among the transmission destination images L1 to Ln, the transmission destination images L4 to L7 are displayed on the display unit 410. When the scroll display stop instruction is received by the touch panel 4101 and the stop instruction receiving unit 525, the display control unit 522 does not set the display state as the display screen of the display unit 410, but in FIG. As shown in the figure, the predetermined number of images is, for example, three, and the display of the transmission destination images L1 to L4 is scroll-displayed on the display unit 410, and the scroll display is stopped.

  As a result, when the desired transmission destination image is displayed, the operator cannot input a stop instruction from the stop instruction receiving unit 525, and even if the input timing of the stop instruction is delayed, the operator-desired image is displayed on the display unit. It becomes easy to be displayed on 410. Thereby, when the image is scroll-displayed on the display unit 410, the visibility for the operator can be improved, and the operator can easily find the desired operation guidance image.

  However, in this embodiment, the speed detector 524 detects the scroll speed when the stop instruction is received by the stop instruction receiver 525, and the display controller 522 scrolls from the speed detector 524. The speed may be acquired, and in S106, the predetermined number of images may be changed according to the scroll speed. For example, the display control unit 522 may perform processing such as increasing the predetermined number of images as the scroll speed increases.

  Next, a ninth embodiment of the display control process of the display unit 410 by the multifunction machine 1 will be described. FIG. 23 is a flowchart illustrating a ninth embodiment of display control processing of the display unit 410 by the multifunction machine 1. 24A to 24D are diagrams showing an example of the display screen of the display unit 410. FIG. The ninth embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the sixth to eighth embodiments is omitted.

  In the ninth embodiment as well, as in the eighth embodiment, the display control unit 522 sequentially displays the transmission destination images L1 to Ln that have a high degree of coincidence between items in the transmission destination images. Scroll to 410.

  In the ninth embodiment, for example, when the multifunction device 1 receives a scroll display instruction (YES in S112), the display control unit 522 responds to the scroll display speed detected by the speed detection unit 524 in S113. Thus, the number of instruction reception images displayed on the display unit 410 is reduced (S114). Here, the display control unit 522 decreases the number of items for each image scroll-displayed on the display unit 410 as the scroll display speed detected by the speed detection unit 524 in S73 increases, and the scroll display speed is increased. The number of items for each image to be scroll-displayed on the display unit 410 is calculated in such a manner that the number is increased as the time becomes slower (S114). The display control unit 522 is determined in advance from the instruction receiving image (any one of the transmission destination images L1 to Ln) scroll-displayed on the display unit 410 when the scroll display stop instruction is received. The display unit 410 displays the transmission destination image that has been displayed by the number of images before (S117).

  For example, as illustrated in FIG. 24A, the display control unit 522 displays four transmission destination images L4 to L7 among the plurality of transmission destination images L1 to Ln on the display unit 410. When scroll display is performed in parallel in the direction (in FIG. 24A, except for the transmission destination images L4 to L7 is not displayed), the scroll display speed detected by the speed detection unit 524 in S113 is a predetermined standard speed S. When the predetermined speed S1 is reached, the number of display items for each destination image displayed on the display unit 410 is reduced to three, for example, as shown in FIG. The items from the hierarchy to “affiliation department”, “affiliation section”, “affiliation staff” are set as display items for each transmission destination image. Furthermore, when the scroll display speed detected by the speed detection unit 524 in S113 reaches a predetermined speed S2 that is faster than the speed S1, the display control unit 522 displays the result as shown in FIG. The number of display items for each destination image to be displayed on the display unit 410 is reduced to, for example, two, which is even smaller than that in the case of the speed S1, and each destination image from the upper hierarchy to “affiliation department” and “affiliation section” is reduced. The display item for.

  In such a display state, when a scroll display stop instruction is received by the touch panel 4101 and the stop instruction receiving unit 525, the display control unit 522 performs the above-described predetermined operation as illustrated in FIG. For example, when the number of images is three, the display of the transmission destination images L1 to L4 is scroll-displayed on the display unit 410, and the scroll display is stopped.

  Thus, when the image is scrolled and displayed at a high change speed that reduces the image visibility of the operator, the number of items of each image is reduced, and the amount of information about each image that the operator visually recognizes Therefore, the operator can easily grasp the contents of each image even during high-speed scroll display.

  Next, a description will be given of a tenth embodiment of display control processing of the display unit 410 by the multifunction machine 1. FIG. FIG. 25 is a flowchart illustrating a tenth embodiment of display control processing of the display unit 410 by the multifunction machine 1. FIG. 26 is a diagram illustrating an example of a display screen of the display unit 410. The tenth embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the sixth to ninth embodiments is omitted.

  In the tenth embodiment, as in the ninth embodiment, the display control unit 522 sequentially displays the transmission destination images L1 to Ln that have a high degree of coincidence between items in the transmission destination images. Scroll to 410.

  In the tenth embodiment, for example, when the multifunction device 1 receives a scroll display instruction (YES in S121), the display control unit 522 displays the scroll display speed detected by the speed detection unit 524 in S123. If it is determined that the standard scroll display speed is lower than the predetermined speed D (YES in S124), scroll display is performed with all items displayed for the destination images L1 to Ln (S130). ). On the other hand, if the display control unit 522 determines that the scroll display speed detected by the speed detection unit 524 in S123 has reached the speed D faster than the standard scroll display speed (NO in S124), As shown in FIG. 26, scroll display is performed in a state where only the items of the highest hierarchy are displayed for the destination images L1 to Ln (S125). Thereafter, the processing (S126 to S129) after the scroll display stop instruction is received by the stop instruction receiving unit 525 is the same as in the ninth embodiment.

  As a result, when the change speed reaches the predetermined speed D, the display control unit 522 displays only the item of the highest layer for each transmission destination image, so that each transmission destination image is displayed on the display unit 410. Even when scroll display is performed at a higher speed, the amount of information to be displayed for each destination image is narrowed down so that the operator can easily identify the attribute and type of each destination image. Thereby, even if each transmission destination image is scroll-displayed at high speed, the operator can easily specify a desired image from each transmission destination image displayed on the display unit 410. In addition, when the scroll display is stopped, all the items constituting each transmission destination image are displayed, so if the operator can easily identify the contents of the displayed transmission destination image, Can sufficiently grasp the contents of each destination image.

  Next, an eleventh embodiment of display control processing of the display unit 410 by the multifunction machine 1 will be described. FIG. 27 is a flowchart illustrating an eleventh embodiment of display control processing of the display unit 410 by the multifunction machine 1. FIGS. 28A and 28B are diagrams showing an example of the display screen of the display unit 410. The eleventh embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the sixth to tenth embodiments is omitted.

  In the eleventh embodiment as well, as in the tenth embodiment, the display control unit 522 displays the transmission destination images L1 to Ln in order by sequentially displaying the transmission images having a high degree of coincidence between items. Scroll to 410.

  In the eleventh embodiment, for example, as shown in FIG. 28A, the display control unit 522 is configured so that the scroll display speed detected by the speed detection unit 524 in S133 is faster than the standard scroll display speed. When it is determined that the speed D has been reached (NO in S134), scroll display is performed in a state where only the items of the highest hierarchy are displayed for the destination images L1 to Ln (S135). When the display stop instruction is received by the stop instruction receiving unit 525 (YES in S136), as shown in FIG. 28B, the display control unit 522 displays the scroll display when the stop instruction for the scroll display is received. Among the destination images L1 to Ln that match the items in the highest hierarchy, the destination image displayed first is displayed side by side as the top. Then, the scroll display is stopped (S137). At this time, the display control unit 522 causes the display unit 410 to display all items for each transmission destination image.

  According to this, when the scroll display is stopped, the stop instruction receiving unit 525 receives a scroll display stop instruction, and when the scroll display is stopped, among the transmission destination images that match the items in the highest hierarchy that are scroll-displayed. Since the destination images displayed first are arranged and displayed at the top, the operator can sufficiently grasp the contents of each destination image that matches the items in the highest hierarchy.

  Next, a description will be given of a twelfth embodiment of the display control process of the display unit 410 by the multifunction device 1. FIG. FIG. 29 is a flowchart illustrating a twelfth embodiment of display control processing of the display unit 410 by the multifunction device 1. FIGS. 30A to 30D are diagrams illustrating an example of the display screen of the display unit 410. The twelfth embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that description of the same processing as in the third embodiment is omitted.

  When the main power supply of the multifunction device 1 is turned on by the operator, the display control unit 522 displays the operation screen (initial screen A) as shown in FIG. 5 described above on the display unit 410 (S141). When the display control unit 522 displays the initial screen A on the display unit 410, for example, when the density button 410 a is touched by the operator, the touch panel 4101 and the instruction receiving unit 523 make an instruction to set the copy density. Is received, the display control unit 522 causes the display unit 410 to display a density setting button 410b (part of the density setting screen) as shown in FIG.

  When the display control unit 522 displays the density setting button 410b, the operator touches any one of the buttons 410b1 to 410b5 constituting the density setting button 410b, and the touch panel 4101 causes the buttons 410b1 to 410b5 to be displayed. When designation of the coordinate position of any display position is accepted (YES in S142), the instruction accepting unit 523 acquires information on the designated coordinate position from the touch panel 4101, and the instruction accepting unit 523 has a built-in timer. Is used to measure the elapsed time since the coordinate position was designated (S143). Note that if the touch panel 4101 does not accept the designation of the coordinate position of any of the buttons 410b1 to 410b5 (NO in S142), the process of S141 is repeated.

  Here, even when the time measured by the instruction receiving unit 523 reaches a predetermined elapsed time (for example, 0.5 seconds), if the touch panel 4101 cannot accept the designation of the next coordinate position (YES in S143), That is, when the operator stops his finger at the coordinate position of any of the display positions of the buttons 410b1 to 410b5, it corresponds to the instruction receiving image (any of the buttons 410b1 to 410b5) displayed at the coordinate position. The instruction to be received is received by the instruction receiving unit 523 (S152).

  On the other hand, if a further coordinate position is accepted by the touch panel 4101 while the time measured by the instruction accepting unit 523 does not reach the predetermined elapsed time (NO in S143) in S143 (YES in S144). The speed detector 524 detects the change direction based on the coordinate positions before and after the change (S145).

  Then, the display control unit 522 scroll-displays the plurality of instruction receiving images (buttons 410b1 to 410b5) to be displayed on the display unit 410 in the change direction detected by the speed detection unit 524 in S145 ( S146). For example, as illustrated in FIG. 30B, when the change direction detected by the speed detection unit 524 in S145 is an arrow direction, the display control unit 522 displays each image of the buttons 410b1 to 410b9 in the direction of the arrow. Are displayed on the display unit 410 in increments of five, and each image is displayed so as to scroll in order.

  Here, when the operator touches any of the buttons 410b1 to 410b9 and the touch panel 4101 receives designation of the coordinate position of any of the display positions of the buttons 410b1 to 410b9 (YES in S147), the instruction is accepted. The unit 523 acquires information on the designated coordinate position from the touch panel 4101, and stops scrolling in a state where the button image (instruction reception image) displayed at the coordinate position is displayed on the display unit 410. (S148). For example, when the operator receives designation of the coordinate position of the display position of the button 410b9, the display control unit 522 displays the image of the button 410b9 in the state where the image of the button 410b9 is displayed, as indicated by a solid line in FIG. The display screen is displayed on the display unit 410 (for example, enlarged display), and as shown by the broken line in FIG. 30C, the display screen in which the image of other buttons not designated by the operator is also displayed. It is displayed on the display unit 410. As described above, the image of the button 410b9 designated by the operator is displayed differently from the image of the other buttons, for example, as shown in FIG. It is preferable.

  When the display screen displaying the image of the button 410b9 designated by the operator as described above is displayed on the display unit 410, the operator touches any of the displayed buttons. When the designation of the coordinate position of any of the displayed buttons is accepted by the touch panel 4101 (YES in S149), the instruction receiving image displayed on the coordinate position (the buttons 410b1 to 410b9). The instruction corresponding to any one is received by the instruction receiving unit 523 (S152).

  In addition, the operator does not accept the designation of the coordinate position of the display position (NO in S149), and the operator performs a predetermined operation on the touch panel 4101 (for example, within a predetermined time, for example, within a time of less than 0.5 seconds). When the instruction accepting unit 523 accepts a scroll display restart instruction (by designating different two-point coordinate positions, etc.) (YES in S150), the display control unit 522 scrolls the image stopped and displayed in S148. Instead of displaying, scroll display is resumed from an image that has been scrolled further than the image stopped and displayed in S148 (S151). For example, the display control unit 522 does not start scroll display from the display state illustrated in FIG. 30C, but starts scroll display from an image that has been scrolled further than the stopped and displayed image. For example, the display control unit 522 performs the scroll display having the same display content as that in the case where the scroll display has been continuously performed without stopping the scroll display started in S146. For example, as shown in FIG. 30 (d), the button 410b9 displayed in the center of the plurality of instruction receiving images in the display state shown in FIG. 30 (c) is scrolled in S150 from the coordinate designation in S147. It is displayed at a position advanced in the arrow direction (change direction) in FIG. 30 (d) by the amount corresponding to the passage of time until the display restart instruction. Thereafter, the process returns to S143.

  However, the process of S151 may be performed as long as the display control unit 522 restarts the scroll display from an image that has been scrolled further than the image stopped and displayed in S148. The above-described scroll display having the same display contents as the case where the scroll display that has been executed in S146 is continued without being stopped is merely an example of the process of S151.

  Thereby, for example, when the operator finds a desired image from among the images scrolled on the display unit 410, the image is displayed as a state in which the desired image is displayed on the display screen of the display unit 410. If the operator has confirmed the content of the image and resumes scroll display, the scroll display will continue as it is without stopping even when the desired image is displayed. Since an image as if it had been displayed is displayed, the waiting time until a desired image is displayed on the display unit 410 can be reduced.

  Next, a description will be given of a thirteenth embodiment of display control processing of the display unit 410 by the multifunction device 1. FIG. FIG. 31 is a flowchart illustrating a thirteenth embodiment of display control processing of the display unit 410 by the multifunction device 1. FIGS. 32A to 32D are diagrams showing examples of the display screen of the display unit 410. The thirteenth embodiment is also a display process when the display control unit 522 causes the display unit 410 to scroll-display the instruction reception image. Note that the description of the same processing as that in the twelfth embodiment will be omitted.

  In the thirteenth embodiment, when the display control unit 522 scrolls the display unit 410 in the direction of change detected by the speed detection unit 524 in S165 (S166), the operator designates the coordinate position. Is received by the touch panel 4101 (YES in S167), the instruction receiving unit 523 acquires information on the designated coordinate position from the touch panel 4101. For example, as shown in FIG. The display control unit 522 displays the image of the displayed button (instruction reception image) on the front of the display screen of the display unit 410 (S168).

  At this time, the display control unit 522 maintains the display state in which the scroll display started in S166 is continued on the back side of the button image (instruction reception image) displayed on the front surface without being stopped ( S169). For example, as shown in FIG. 32A, the display control unit 522 stops the scroll display of each button on the back in the state shown in FIG. 31A even if the button image is displayed on the front. Instead, as shown in FIG. 32 (b) and further FIG. 32 (c), the scroll display is advanced.

  Then, when an instruction to restart scroll display (an instruction to stop button image display on the front side) is received by the instruction receiving unit 523 (YES in S171), the display control unit 522 displays the button image on the front side. The display is stopped and not displayed. The scroll display started in S166 and continued in S196 is displayed on the front surface of the display screen of the display unit 410 (S172). For example, as shown in FIG. 32D, the display control unit 522 indicates that the button 410b8 displayed second from the left in the display state shown in FIG. It is displayed at a position further advanced in the direction of change). Thereafter, the process returns to S163.

  As a result, when the operator finds a desired image from among the images scroll-displayed on the display unit 410, the content of the image is displayed as a state in which the desired image is displayed on the display screen of the display unit 410. Each image sequentially displayed on the display unit 410 by scroll display can also be visually recognized.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, the configuration and processing according to the embodiment shown in FIGS. 1 to 34 are merely examples of the configuration and processing of the image forming apparatus according to the present invention, and the configuration and processing of the image forming apparatus according to the present invention are the same. The contents are not limited to those described above.

  Furthermore, although the image forming apparatus according to the present invention has been described as the multifunction device 1, the image forming apparatus according to the present invention is not limited to the multifunction device, and may be a copier, a facsimile machine, a printer, or the like.

  In the above embodiment, the change speed detected by the speed detection unit 524 is used for the process of changing the display form of the instruction receiving image. However, the change speed is not limited to the above-described change speed. Further, acceleration at the time of changing the coordinate position, scroll amount at the time of scroll display, or the like may be used. In this case, the acceleration and the scroll amount may be detected by the speed detection unit 524 or the like.
