Description

The present invention includes a display unit capable of displaying an operation screen of an image forming apparatus such as an MFP (Multi Function Peripherals) which is a multifunction digital multi-function peripheral, for example, and the operation of the image forming apparatus by a touch operation on the display unit The present invention relates to an operation input device for an image forming apparatus that can perform the operation, a display control method for an operation screen executed by the input device , and a program .

  As portable information terminals (also referred to as tablet terminals) on which various applications can be installed are widespread, users who use image forming apparatuses, for example, MFPs, want to operate MFPs using their own tablet terminals. There are many requests. Therefore, by installing a dedicated application and displaying an operation screen or hard key of the MFP on the display unit of the tablet terminal, the MFP can be operated from the tablet terminal.

  However, in such a tablet terminal, when the user grips the edge of the display unit, if the palm of the hand is inadvertently put on or touches the operation key on the display screen, it is erroneously detected that the operation key is pressed. Then, the operation key is turned on unintentionally, or since it is an electrostatic touch panel, it is determined that the operation key is kept pressed, so that the touch operation of other operation keys cannot be performed. May cause problems.

  In order to solve this problem, a handle detection sensor is provided at the edge of the display part of the tablet terminal, and when the user grips the tablet terminal, if the handle is detected by the sensor, the screen display part or the detection area There is known a technique for preventing erroneous detection of the operation keys by reducing the width or correcting the width so as to be avoided from the handle.

  Conventionally, in an input device equipped with a touch panel, a detection means for detecting that the user places a hand on the armrest portion at a predetermined position is provided, and is displayed on the display means when the user places a hand on the armrest portion. By moving and displaying the input acceptance button that is operated by touching it closer to a predetermined position than when no hand is detected, for example, input operation can be performed without much influence of shaking in the state of being mounted on a car. A technique that has been made possible has been proposed (see, for example, Patent Document 1).

  By the way, since the display unit and the touch operation unit are integrated in the operation screen of the MFP, when the touch operation unit is reduced as in the technique described above, the display unit is also reduced. In that case, the operation keys displayed in the screen are also reduced and reduced, or the keys are reduced and the arrangement of keys on the display unit is changed randomly. For this reason, even if a desired key is to be pressed, there is a risk that another key will be pressed by mistake, and the relationship between each key may become difficult to understand, which may result in erroneous key input.

  For this reason, even if the display unit is reduced, it is desired to keep the key size and layout as much as possible. However, since the display area itself becomes small, it is difficult to target all keys.

  Therefore, it is desirable to maintain a display format such as key size / layout preferentially so as to maintain the original operability at least for the keys having high importance among the operation keys.

  FIG. 4 is a flowchart showing the flow of display control processing when the user's handle holding the portable information terminal 2 is detected by the sensor 291. 4 and the subsequent flowcharts are executed by the CPU 201 of the portable information terminal 2 operating according to an operation program stored in the ROM 202 or the like.

  In FIG. 4, in step S <b> 1, in a state where the operation screen displayed on the operation panel unit 130 of the MFP 1 is displayed on the display unit 220 of the portable information terminal 2, the user operates the display unit 220 of the portable information terminal 2. When the edge portion 20a is gripped, the handle detection sensor 291 detects the handle, and the touch detection area is reduced and corrected so that the handle does not cover the key position. At this time, since the screen display area is integrated with the touch detection area, the screen display area is simultaneously reduced and corrected, and the displayed operation screen is also reduced.

  In step S2, it is determined whether or not there is an operation key whose display format should be determined with priority in the display screen. If there is an operation key whose display format should be determined with priority (YES in step S2), step S2 is performed. In S3, the priority of each displayed key is determined based on the type of the MFP operation screen, and the priority order is determined (allocated) for each key. In step S4, the display process for determining the display format of the operation key with the n-th priority is started by setting n = 1, and then the process proceeds to step S5.

  If there is no operation key whose display format should be determined with priority (NO in step S2), in step S9, the operation key display format (size and / or layout of the operation key) is determined in accordance with the operation key displayable area. After that, the process proceeds to step S8.

  Note that the type and priority order of operation keys whose display format is to be determined in advance are set in advance according to the type of operation screen on which the operation key is displayed, and the fixed storage device of the portable information terminal 2 210 is stored as information, and the mobile terminal determines the priority order based on this information. Note that preset information regarding the priority order of the operation keys may be stored in the fixed storage device 110 of the MFP 1 and the priority order may be determined by the portable information terminal 2 acquiring the information from the MFP 1. .

  In step S5, when the priority order of the operation keys is determined, it is determined whether or not the operation key size is preferentially maintained for each priority order. In step S5, YES, and in step S6, after determining the display format to maintain the size, the process proceeds to step S7. At this time, the reduced key displayable area is automatically determined, and the key layout and the like are determined in the area. The key displayable area is determined by excluding, for example, an area where a message is displayed.

  In the case of an operation key that does not preferentially maintain the size (NO in step S5), in step S10, after determining the display format that maintains the layout in accordance with the key displayable area, the process proceeds to step S7.

  Note that the operation key for preferentially maintaining the size or the operation key for preferentially maintaining the layout is also set in advance based on the type of the displayed operation screen, the type of the operation key, and the like. Are stored in the fixed storage device 210 and the fixed storage device 110 of the MFP 1.

  In the case where priority is given to the size or the layout, if both the size and the layout can be maintained in the key displayable area, both are maintained.

  In step S7, it is determined whether or not the display format of the operation keys has been determined for each priority, that is, whether or not the determination for all keys has been completed. If not (NO in step S7), step S11 is performed. In step S5, the variable n is set to n = n + 1. If completed (YES in step S7), the screen is redrawn in step S8.

  In this embodiment, when all the operation keys have the same priority, all the operation keys are resized by changing the size / layout according to the area where the keys can be displayed. . Further, even if the operation key has a lower priority order, even if the display format should maintain the size or layout, as a result of maintaining the size or layout of the operation key having a higher priority order, there is less free space in the key displayable area. If the size or layout to be maintained cannot be maintained, the size may be reduced or the layout may be changed.

  5A to 5C show the case where the user's handle holding the portable information terminal 2 is detected by the sensor 291 while the print output mode setting screen of the MFP 1 is displayed on the portable information terminal 2. It is a figure which shows the example of a display.

  In this embodiment, one or a plurality of independent mode setting keys such as “color” and “paper setting” are used as the first priority operation keys to determine the display format. When the key is on the screen, the operation keys that are not directly related to the print output mode setting, such as the detailed setting key and the page switching key, are preset so that the priority is lower than the mode setting key. ing.

  When the user grips the edge 20a of the display unit 220 of the portable information terminal 2, as shown on the screen Da in FIG. 5A, the region that the user covers is detected by the handle detection sensor 291. Then, the display on the screen is reduced. At that time, the mode setting key K1 having a high importance is given the first priority in the order of determining the display format of the operation keys. In this screen Da, function badge (badge) keys such as “color” and “paper setting” correspond to the print output mode setting key K1.

  Since these operation keys K1 have no meaning in maintaining the layout, the size is maintained as shown in the screen Db in FIG. 5B. In this case, if the size cannot be maintained while maintaining the original layout in the key displayable area, the layout (arrangement) of the key K1 is changed.

  When the layout of the function badge key K1 having the first priority is determined, as shown in the screen Dc of FIG. 5C, the other remaining keys, for example, the key K2 having a low priority such as a menu key or a detail confirmation key are arranged. The display format is determined by changing the size and / or layout as necessary in accordance with the empty area of the key displayable area, and each key is displayed in the determined display format.

  FIGS. 6A to 6C show a state in which the base adjustment screen is displayed as the print output mode setting screen on the portable information terminal 2, and the user's handle holding the portable information terminal 2 is detected by the sensor 291. FIG.

  Here, as setting keys for the print output mode, a plurality of meaningful level output selection keys K10 are displayed in descending / ascending order with respect to level setting, such as a background adjustment level selection key. Since these level output selection keys K10 have meanings, the priority order is set to the first place in order to determine the display format in preference to other mode setting keys, and other mode setting The key has the second priority.

  When the user grips the edge portion 20a of the display unit 220 of the portable information terminal 2, as shown in the screen Da in FIG. 6A, an area that is covered with the handle is detected by the handle detection sensor 291. The display of the operation screen is reduced, but the level output selection key has a key display format prioritizing maintaining the layout rather than the size as shown in the screen Db of FIG. Is determined.

  If there is a remaining key K20 other than the level output selection key and the mode setting key, the priority order of these keys is the third order, and as shown in the screen Dc of FIG. Each time, the display format of the operation key is determined while giving priority to the display format of the upper operation key.

  FIG. 7 shows the flow of the display control process when the user's handle holding the portable information terminal 2 is detected by the sensor 291 while the print output mode setting screen is displayed on the portable information terminal 2. It is a flowchart.

  In FIG. 7, the user holds the edge 20 a of the display unit 220 of the portable information terminal 2 while the print output mode setting screen displayed on the operation panel unit 130 of the MFP 1 is displayed on the portable information terminal 2. In step S21, the handle is detected by the handle detection sensor 291, and the touch detection area is reduced and corrected so that the position of the key is not covered by the handle. At this time, the operation screen is also reduced and corrected.

  In step S22, it is determined whether or not there is an independent print output mode setting key on the operation screen. If there is (YES in step S22), the process proceeds to step S23. If not (NO in step S22), in step S30. Then, after determining the display format of the operation key together with the operation key displayable area, the process proceeds to step S29. In this case, for example, all keys are reduced in accordance with the reduction of the screen.

  In step S23, it is determined whether there are a plurality of level output selection keys in the print output mode setting key. If there is a level output selection key (YES in step S23), in step S24, the level output setting selection key is selected. The priority is determined by setting the key as the key that gives priority to the first, and the other mode setting key (function badge key) as the key that gives priority to the second, and the process proceeds to step S25. If the print output mode setting key does not have a level output selection key (NO in step S23), in step S31, the mode setting key (function badge key) is determined as the first priority key, and then in step S25. move on.

  In step S25, the process for determining the display format of the operation key with the n-th priority is started by setting n = 1, and in step S26, it is determined whether or not the operation key is a level output selection key. If it is a level output selection key (YES in step S26), in step S27, a display format that maintains the layout in accordance with the key displayable area is determined, and then the process proceeds to step S28. If it is not a level output selection key (NO in step S26), in step S32, a display format that maintains the size in the key displayable area is determined, and then the process proceeds to step S28.

  In step S28, it is determined whether or not the determination process (display format determination process) has been completed for all keys. If not (NO in step S28), the variable n is set to n = n + 1 in step S35. Return to step S26. If the determination process is completed for all keys (YES in step S28), redrawing of the screen is executed in step S29.

  When operation keys other than the level output selection key and the mode setting key are included, the display format of the operation keys is determined so that these keys are within the operation key displayable area.

  In this manner, priority is given to the operation keys in accordance with the contents of the print output mode setting screen displayed on the portable information terminal 2, and whether to maintain the layout or the size is determined in accordance with the operation keys. Thus, even if the print output mode setting screen is reduced, the operability of each operation key can be maintained.

  FIG. 8 is a diagram showing a data transmission output setting screen D0 for selecting a data transmission destination and setting a data transmission mode, such as Scan To E-mail / Fax in the MFP 1, by the portable information terminal 2. FIG. 9 is a diagram showing the setting screen D1 after the data transmission destination is selected on the screen D0.

  When the user is holding the edge 20a of the display unit 220 of the portable information terminal 2 while the setting screens D0 and D1 of FIGS. 8 and 9 are displayed, the handle is detected by the sensor 291 and each setting is performed. Assume that the screens D0 and D1 have been reduced.

  At this time, as shown in the setting screen D0, if the destination type is not selected (number of destinations = 0), the transmission job such as Scan transmission / Fax or transmission to the box of the MFP 1 must be executed. Since it is necessary to select the destination type, the key related to the determination of the destination type has the highest priority.

  Therefore, when the destination type is not selected, the first priority key is the destination type selection key (“FAX”, “E-mail”, “Internet FAX”, “file transmission”, etc.) KA in FIG. The second priority key is a transmission mode setting key (“color”, “read size”, “document name / subject name”, etc.) KB. Other detailed setting keys (“setting confirmation”) KC and the like have the third priority.

  Also, as shown in the setting screen D1 of FIG. 9, if the destination type has already been selected (for example, the number of destinations = 1), the first priority key is the transmission mode setting key (“color”, “read size”). "Document name / subject" etc.) KB, and the destination type selection key ("fax", "E-mail", "Internet fax", "file transmission", etc.) KA is changed to the second priority key It is supposed to be.

  In this way, if the operation key for which the priority order is determined has no meaning in the layout and is an independent operation key, the display format for maintaining the size is determined, and if the key has a meaning in the layout, The display format is determined to be maintained and displayed. In this example, both the destination type selection key KA and the transmission mode setting key KB are independent operation keys having no meaning in the layout, and are therefore displayed while maintaining the size of the operation keys.

  FIG. 10 shows the flow of the display control process when the user's handle holding the portable information terminal 2 is detected by the sensor 291 while the data transmission output setting screen is displayed on the portable information terminal 2. It is a flowchart.

  In FIG. 10, the user holds the edge 20a of the display unit 220 of the portable information terminal 2 while the data transmission output setting screen displayed on the operation panel unit 130 of the MFP 1 is displayed on the portable information terminal 2. If so, the handle is detected by the handle detection sensor 291 and the touch detection area is reduced and corrected so that the key does not cover the handle.

  In step S41, it is determined whether or not the destination type has been selected. If the destination type has been selected (YES in step S41), in step S48, the data transmission mode setting key is given priority to the first key, etc. After determining the priority as the second priority key, the process proceeds to step S43. If the destination type has not been selected (NO in step S41), in step S42, the priority order is determined using the destination type selection key as the first priority key and the other mode setting key as the second priority key. The process proceeds to step S43.

  In step S43, f and the n-th priority operation key display format determination process are started by setting n = 1, and then the process proceeds to step S44.

  In step S44, it is determined whether or not to preferentially maintain the size of the operation key. If it is not the operation key that preferentially maintains the size (NO in step S44), in step S49, the layout is displayed in the key displayable area. The display format is maintained, and the process proceeds to step S46. If it is an operation key that preferentially maintains the size (YES in step S44), in step S45, a display format that maintains the size in the key displayable area is determined, and the process proceeds to step S46.

  In step S46, it is determined whether or not the determination process has been completed for all keys. If not (NO in step S46), in step S50, the variable n is set to n = n + 1, and then the process returns to step S44. . If the determination process has been completed for all keys (YES in step S46), screen redrawing is executed in step S47.

  As described above, the priority is given to the operation keys of the data transmission output setting screen displayed on the portable information terminal 2, and it is determined whether to maintain the layout or the size according to the operation keys. Even if the transmission output setting screen is reduced, the operability of each operation key can be maintained.

  11 and 12 show the in-box document output setting screen when the portable information terminal 2 performs output setting of the document in the box which is the storage area of the MFP 1, and FIG. 11 shows the setting when no document is selected. FIG. 12 is a diagram showing a setting screen D11 when the same document has been selected.

  While the screens D10 and D11 shown in FIGS. 11 and 12 are displayed, the user's handle holding the edge 20a of the display unit 220 of the portable information terminal 2 is detected, and the display screens D10 and D11 are reduced. Suppose that

  At this time, as shown in the display screen D10 of FIG. 11, when the document in the box is not selected, it is essential to select the document when executing operations such as printing, transmission, and document deletion. Therefore, the document selection (document list) key (“screen image”, “specification”, etc.) KX that can be selected from the listed documents has the highest priority.

  For this reason, when no document is selected, the first priority key is the document list key KX in FIG. 11, and the second priority key is the mode setting key (“print key”, “Send key”, “Delete key”, etc.) KY. Further, the third priority is set to other detailed setting keys KZ and the like.

  As shown in the display screen D11 of FIG. 12, if the document in the box has already been selected, the first priority key is the mode setting key (“print key”, “send key”, “delete key”). Etc.) KY, and the document selection key KX is changed to the second priority key.

  If the operation keys thus determined in priority order are independent and independent operation keys, the display format for maintaining the size is determined, and if the operation keys are meaningful, the display format for maintaining the layout is determined. It is supposed to be determined.

  FIG. 13 shows the flow of display control processing when the handle of the user holding the portable information terminal 2 is detected by the sensor 291 in a state where the in-box document output setting screen is displayed on the portable information terminal 2. It is a flowchart to show.

  In FIG. 13, the user holds the edge 20 a of the display unit 220 of the portable information terminal 2 while the in-box document output setting screen displayed on the operation panel unit 130 of the MFP 1 is displayed on the portable information terminal 2. If so, the handle is detected by the handle detection sensor 291, the touch detection area is corrected for reduction so that the position of the key is not covered by the handle, and the operation screen is also reduced.

  In step S61, it is determined whether or not the document in the box in the MFP 1 is selected. If the document is selected (YES in step S61), the document output mode setting key KY is given first priority in step S68. After the priority order is determined with the key and the other operation keys as the second priority keys, the process proceeds to step S63. If no document is selected (NO in step S61), in step S62, the document selection key KX is set as the first priority key, and the document output mode setting key KY is set as the second priority key. After the determination, the process proceeds to step S63.

  In step S63, the display format determination process of the n-th priority operation key is started by setting n = 1 (n = 1), and the process proceeds to step S64.

  In step S64, it is determined whether or not to preferentially maintain the size of the operation key. If it is not an operation key that preferentially maintains the size (NO in step S64), in step S69, the key displayable area is selected. The display format maintaining the layout is determined, and the process proceeds to step S66. If it is an operation key that preferentially maintains the size (YES in step S64), in step S65, a display format in which the size is maintained in the key displayable area is determined, and the process proceeds to step S66.

  In step S66, it is determined whether or not the determination process has been completed for all keys. If not (NO in step S66), the variable n is set to n = n + 1 in step S70, and the process returns to step S64. . If the determination process has been completed for all keys (YES in step S66), screen redrawing is executed in step S77.

  In this way, the priority is given to the operation keys of the in-box document output setting screen displayed on the portable information terminal 2, and it is determined whether to maintain the layout or the size according to the operation keys. Even if the setting screen is reduced, the operability of each operation key can be maintained.

  In the above embodiment, a screen transition key is newly provided when the lower priority display key cannot be displayed in the empty area of the key displayable area after the display format of the operation key having the higher priority is determined. The lower priority display key may be displayed on the transition destination screen when the screen transition key is pressed.

  By the way, in the above embodiment, the priority order is determined for the operation keys for each display screen, and when the portable information terminal 2 detects the user's handle, the display format of the operation keys is automatically determined for each priority order. It is a thing. In addition to this, in the MFP 1 that can perform authentication management for each user, the administrator or the like can set and save an operation key having a high priority as its own user information for each user in the administrator setting or the like. The mobile information terminal 2 may be configured to determine the set operation key as the first priority based on the user information. In this case, the user's intention can be reflected in the priority order.

  For example, the MFP 1 or the portable information terminal 2 determines that the overall print output mode has a high priority. However, as user authentication information, the priority of the keys of the layout group is set high in the print output mode. It is also possible to determine the display format of a key such as a booklet or binding margin first.
