  In the following description, the initial state of the display area 30 means that the display area 30 has a size before a scroll operation such as a flick operation is performed on the display area 30, and a plurality of options. Is displayed in the display area 30 as a list.

  First, when the display area 30 is in an initial state, the touch sensor section 20b detects a flick operation or a drag operation that is performed on the display area 30 displayed on the display section 20a using a touch pen or the like ( Step S101; Yes). When a flick operation or the like is detected by the touch sensor unit 20b, the CPU 10 determines whether or not the display area 30 is an enlargement target area based on a predetermined determination criterion (step S102). As the predetermined determination criterion, for example, if the number of options that cannot be displayed in the display area 30 before a flick operation or the like is performed is a predetermined number or more, it is determined that the display area 30 is an enlargement target area. Alternatively, it may be determined whether the display area 30 is an enlargement target area according to the type of the list of options.

  If it is determined that the display area 30 is an enlargement target area (step S102; Yes), the display area 30 is enlarged by the instruction signal from the CPU 10, and scrolled in the enlarged state (step S103). . On the other hand, when it is determined that the display area 30 is not the enlargement target area (step S102; No), the display area 30 is scrolled without being enlarged (step S104).

  After the display area 30 is scrolled in the enlarged state in step S103, it is determined whether any option displayed in the display area 30 has been selected (step S105).

  When selection of an option is detected by pressing a location of the touch sensor unit 20b corresponding to the option with a touch pen or the like, the CPU 10 determines that any option has been selected (step S105; Yes). In response to the instruction signal from the CPU 10, the display area 30 enlarged in step S103 is returned to the initial size (step S106). That is, the enlarged display area 30 is reduced to the size before the flick operation or the like is executed. Furthermore, the display area 30 is controlled by the CPU 10 so that the selected option is displayed in the display area 30 returned to the initial state, and a series of controls on the display area 30 is completed.

  After scrolling in a state where the display area 30 is enlarged in step S103, for example, when an option corresponding to a desired operation instruction is not found, selection of an option is not detected (step S105; No). It is determined whether or not an unrelated area 40 (see FIG. 3) that is an area other than the display area 30 that is not related to is selected (step S107).

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (Step S107; Yes), and the display area 30 is returned to the initial state (Step S107). S108). Specifically, when the selection of the unrelated area 40 is detected by pressing a part of the touch sensor unit 20b corresponding to the screen area other than the display area 30 with a touch pen or the like, the enlargement is performed by an instruction signal from the CPU 10. The displayed display area 30 is returned to the initial state, and a series of controls for the display area 30 is completed.

  Furthermore, if selection of the unrelated area 40 is not detected in step S107 (step S107; No), the process returns to step S105 again, and selection of an option (step S105) or selection of the unrelated area 40 (step S107) is detected. The monitoring state continues.

  On the other hand, when it is determined in step S102 that the display area 30 is not the enlargement target area (step S102; No), the display area 30 is scrolled without being enlarged (step S104) and then displayed in the display area 30. It is determined whether any of the selected options has been selected (step S109).

  When selection of an option is detected by pressing the location of the touch sensor unit 20b corresponding to the option with a touch pen or the like, the CPU 10 determines that any option has been selected (step S109; Yes), and displays A series of control for the region 30 ends.

  If selection of an option is not detected (step S109; No), it is determined whether or not the unrelated area 40 is selected (step S110), as in step S107.

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (step S110; Yes), and the series of controls for the display area 30 is completed.

  Furthermore, if selection of the unrelated area 40 is not detected in step S110 (step S110; No), the process returns to step S109 again, and selection of an option (step S109) or selection of the unrelated area 40 (step S110) is detected. The monitoring state continues.

  3A, 3B, and 3C, when the display area 30 is enlarged by a flick operation or a drag operation, that is, when the display area 30 is determined to be an enlargement target area (FIG. 2). It is explanatory drawing which shows the change of the state of the display area 30 in middle step S102; refer (Yes).

  3A, 3 </ b> B, and 3 </ b> C, the display unit 20 a of the operation display unit 20 includes a display region 30 that displays a plurality of options, and a region other than the display region 30 that is not related to selection of options. A non-related area 40 is displayed.

  The display area 30 includes a list display area 31 for displaying a plurality of options as a list, and a scroll bar 32 for executing a scroll operation. In the examples shown in FIGS. 3A, 3B, and 3C, a list of destinations in facsimile communication or the like is displayed in the list display area 31, and each option represents a destination registered in advance.

  In the non-related area 40, tab information such as TAB1 and TAB2 displayed above the display area 30 when the display area 30 is in the initial state, Home, and a message such as “Select Desired Destination.” Are displayed. For example, information that is not used when a specific option is selected from a plurality of options displayed in the list display area 31 of the display area 30, such as a message field for the message field.

  First, after a flick operation or the like is performed on the display area 30, the display area 30 is enlarged, and the display area 30 is initialized by selecting a specific option from among a plurality of options displayed on the display area 30. A change in the state of the display area 30 until the state is returned will be described.

  In FIG. 3A, when the display area 30 is in the initial state, nine options (registered destinations) from A1 to C3 are displayed in the form of 3 rows × 3 columns. In this initial state, a flick operation or a drag operation is executed in the vertical direction on the list display area 31 of the display area 30.

  When a flick operation or the like is performed on the list display area 31 in the upward or downward direction, as shown in FIG. 3 (b), the display area 30 extends vertically to the upper and lower ends of the display screen of the display unit 20a. Expanding. In addition, the list display area 31 is expanded in the vertical direction together with the display area 30, and the scroll bar 32 extends in the vertical direction.

  When the display area 30 is enlarged in the vertical direction and is in an enlarged state, some information displayed in the unrelated area 40 is hidden by the enlarged display area 30. The hidden information includes tab information such as TAB1 and TAB2 displayed above the display area 30 in the initial state, a message field for displaying a message such as “Home” and “Select Desired Destination.”. And a Detail button displayed below the display area 30. These pieces of information are information that is not used when a specific option is selected from a plurality of options displayed in the list display area 31 of the display area 30, that is, information that is not related to the selection of the specific option. When a specific option is selected from a plurality of options after the display region 30 is enlarged by a flick operation or the like with respect to the display region 30, the display unit 20a displays a plurality of options and, if necessary, accompanying information regarding these options. Etc., and tab information not related to the selection of a specific option need not be displayed. Therefore, even if the display area 30 is enlarged so as to hide information that is not related to selection of options, the selection of options is not affected.

  When the display area 30 is in an enlarged state, the list display area 31 displays 15 options (registered destinations) from A1 to E3 in the form of 5 rows × 3 columns. In this enlarged state, option B2 (in the example of FIG. 3B, a transmission destination in facsimile communication or the like) corresponding to a desired operation instruction to the image processing apparatus 1 is selected.

  If the option B2 is selected when the display area 30 is in the enlarged state, the display area 30 is returned to the initial state as shown in FIG. That is, the enlarged display area 30 is reduced to the size before the flick operation or the like is executed. The list display area 31 is reduced together with the display area 30, and the scroll bar 32 is shortened. Further, the reduced display area 30 is arranged at the same position as in FIG. Information hidden by the enlarged display area 30 such as tab information is displayed again as in FIG.

  When the display area 30 is returned to the initial state, the selected option B2 is displayed in the reduced list display area 31. In the example shown in FIG. 3C, when the display area 30 is returned to the initial state, the option B2 is displayed on the top line of the list display area 31. Furthermore, the information hidden when the display area 30 is in the enlarged state is displayed again on the display unit 20a.

  In FIG. 3C, when the display area 30 is returned to the initial state, the selected option B2 is displayed at the center of the top line of the reduced list display area 31, but the selected option is reduced. As long as the selected option is displayed in the list display area 31, the position where the selected option is displayed may be arbitrary.

  Next, in a state where the display area 30 is enlarged by a flick operation or the like, a specific option is not selected from a plurality of options displayed in the display area 30, and an unrelated area 40 that is not related to selection of the option is displayed. With reference to FIGS. 3B and 3C for the change in the state of the display area 30 until the display area 30 is returned to the initial state by the selection (see step S107 in FIG. 2; Yes and step S108). While explaining.

  When the display area 30 is in an enlarged state, for example, if a choice corresponding to a desired operation instruction is not found even if a flick operation or the like is executed, and the choice is not selected, in order to cancel the enlarged state, FIG. The unrelated area 40 shown in 3 (b) is selected. Specifically, when the non-related area 40 is selected by pressing the location of the touch sensor unit 20b corresponding to the non-related area 40 with a touch pen or the like, the enlarged display area 30 is displayed by an instruction signal from the CPU 10. , The initial state as shown in FIG.

  In FIG. 3B, the Search button, the App button, and the like are displayed in the unrelated area 40, but the display area 30 may be returned to the initial state by pressing the Search button or the App button. Further, even if the display area 30 is returned to the initial state by pressing a blank area other than the Search button or the App button in the unrelated area 40 or a part of a message field that is not hidden when the display area 30 is enlarged. Good.

  FIGS. 4A, 4B, and 4C are explanatory views schematically showing changes in the state of the display area 30 when the scroll position of the list display area 30 before the flick operation is at the head of the list. .

  4A, 4B, and 4C, 63 options A1 to U3 are listed and stored in the nonvolatile memory 16 or the like, but 63 are displayed in the list display area 31 of the display area 30. All of the options are not displayed at once. By executing the flick operation on the list display area 31, the list display area 31 is scrolled, and the options are displayed in the scroll display direction in order in the scroll direction.

  The “default area” shown in FIGS. 4A, 4B, and 4C is a display range of the list display area 31 when the display area 30 is in the initial state. In the example of FIGS. 4A, 4B, and 4C, nine options are displayed in the form of 3 rows × 3 columns in the “default area”. The “enlarged area” is a display range that is further enlarged from the default area when the display area 30 is in an enlarged state. In the example of FIGS. 4A, 4B, and 4C, when the flick operation is executed in the upward direction, the display range of 2 rows × 3 columns is displayed above the default area, and 1 is displayed below the default area. The display range for the row X3 columns is added to the display range of the list display area 31 as an enlarged area. Accordingly, in the examples of FIGS. 4A, 4B, and 4C, when the display area 30 is in an enlarged state, a maximum of 18 options are displayed in the form of 6 rows × 3 columns in the list display area 31. Is done. 4A, 4 </ b> B, and 4 </ b> C, a portion indicated by a white square represents a display range of the list display area 31 in each state of the display area 30, and is indicated by a gray square. The portion (excluding the selected option) represents a range that is not displayed by the list display area 31 in each state of the display area 30.

  In FIG. 4A, when the display area 30 is in the initial state, only the default area is the display range of the list display area 31. In addition, since the scroll position of the list display area 31 before the flick operation is at the top of the list, nine options from A1 to C3 are displayed in the list display area 31.

  When the display area 30 is in the initial state shown in FIG. 4A, if an upward flick operation is performed on the list display area 31, an enlarged area is added to the display range of the list display area 31. . In addition, since the flick operation is performed on the list display area 31 in the upward direction, the default area is scrolled downward. Furthermore, the enlarged area added together with the default area is also scrolled downward.

  In the example of FIG. 4B, the default area is scrolled downward from the initial state by two lines in the list by a flick operation. Also, the enlarged area is scrolled downward by two lines in the list together with the default area. Therefore, when the display area 30 is in an enlarged state, 18 options from A1 to F3 are displayed in the list display area 31.

  When option B2 is selected when the display area 30 is in the enlarged state, the display area 30 is returned to the initial state as shown in FIG. 4C, and the display range of the list display area 31 is only the default area. . That is, when the option B2 is selected, the list display area 31 of the display area 30 is reduced by the enlarged area.

  When the display area 30 is returned to the initial state, the selected option B2 is displayed in the default area, that is, in the center of the top line of the reduced list display area 31. By displaying the selected option B2 in the reduced list display area 31, the selected option can be confirmed even after the list display area 31 is reduced.

  In FIG. 4C, when the display area 30 is returned to the initial state, the selected option B2 is displayed in the center of the top row of the default area. However, the selected option is displayed in the default area. For example, the position where the selected option is displayed may be arbitrary.

  FIGS. 5A, 5B, and 5C are explanatory views schematically showing changes in the state of the display area 30 when the scroll position of the list display area 31 before the flick operation is in the middle of the list. .

  The list of options shown in FIGS. 5 (a), (b) and (c) is the same as the list of options shown in FIGS. 4 (a), (b) and (c). Also, the meaning and specific example of “default area” and the meaning and specific example of “enlarged area” used in the description related to FIGS. 5 (a), (b) and (c) are shown in FIGS. ) And (c) are the same as those used in the description. Further, the meanings relating to the white squares and the gray squares are the same as those used in the description relating to FIGS. 4 (a), (b) and (c).

  In FIG. 5A, when the display area 30 is in the initial state, only the default area is the display range of the list display area 31. The list display area 31 displays nine options from J1 to L3.

  When the display area 30 is in the initial state shown in FIG. 5A, if an upward flick operation is performed on the list display area 31, an enlarged area is added to the display range of the list display area 31. . In addition, since the flick operation is performed on the list display area 31 in the upward direction, the default area is scrolled downward. Furthermore, the enlarged area added together with the default area is also scrolled downward.

  In the example of FIG. 5B, the default area is scrolled downward from the initial state by two lines in the list by a flick operation. Also, the enlarged area is scrolled downward by two lines in the list together with the default area. Accordingly, when the display area 30 is in an enlarged state, 18 options from J1 to O3 are displayed in the list display area 31.

  When the option K2 is selected when the display area 30 is in the enlarged state, the display area 30 is returned to the initial state as shown in FIG. 5C, and the display range of the list display area 31 is only the default area. . That is, when the option K2 is selected, the list display area 31 of the display area 30 is reduced by the enlarged area.

  When the display area 30 is returned to the initial state, the selected option K2 is displayed in the center of the default area, that is, the top line of the reduced list display area 31. By displaying the selected option K2 in the reduced list display area 31, the selected option can be confirmed even after the list display area 31 is reduced.

  In FIG. 5C, when the display area 30 is returned to the initial state, the selected option K2 is displayed at the center of the uppermost line of the default area. However, the selected option is displayed in the default area. For example, the position where the selected option is displayed may be arbitrary.

  6A, 6B, and 6C are explanatory views schematically showing changes in the state of the display area 30 when the scroll position of the list display area 31 before the flick operation is near the tail of the list. It is.

  The list of options shown in FIGS. 6 (a), (b) and (c) is the same as the list of options shown in FIGS. 4 (a), (b) and (c). Also, the meaning and specific example of “default area” and the meaning and specific example of “enlarged area” used in the description related to FIGS. 6 (a), (b) and (c) are shown in FIGS. ) And (c) are the same as those used in the description. Further, the meanings relating to the white squares and the gray squares are the same as those used in the description relating to FIGS. 4 (a), (b) and (c).

  In FIG. 6A, when the display area 30 is in the initial state, only the default area is the display range of the list display area 31. The list display area 31 displays nine options from Q1 to S3.

  When the display area 30 is in the initial state shown in FIG. 6A, if an upward flick operation is performed on the list display area 31, an enlarged area is added to the display range of the list display area 31. . In addition, since the flick operation is performed on the list display area 31 in the upward direction, the default area is scrolled downward. Furthermore, the enlarged area added together with the default area is also scrolled downward.

  In the example of FIG. 6B, the default area is scrolled downward from the initial state by two lines in the list by a flick operation. Also, the enlarged area is scrolled downward by two lines in the list together with the default area. The enlarged area added below the default area displays a blank line one line below the line where the options U1, U2 and U3 are displayed. Therefore, when the display area 30 is in an enlarged state, the list display area 31 displays 15 options from Q1 to U3 and one blank line. By displaying a blank line in the enlarged area added below the default area, the user can recognize that the scroll position of the list display area 31 is at the end of the list.

  When the option R2 is selected when the display area 30 is in the enlarged state, the display area 30 is returned to the initial state as shown in FIG. 6C, and the display range of the list display area 31 is only the default area. . That is, when the option R2 is selected, the list display area 31 of the display area 30 is reduced by the enlarged area.

  When the display area 30 is returned to the initial state, the selected option R2 is displayed in the center of the default area, that is, the top line of the reduced list display area 31. The selected option R2 is displayed in the reduced list display area 31, so that the selected option can be confirmed even after the list display area 31 is reduced.

  In FIG. 6C, when the display area 30 is returned to the initial state, the selected option R2 is displayed at the center of the top row of the default area. However, the selected option is displayed in the default area. For example, the position where the selected option is displayed may be arbitrary.

  FIG. 7 is a flowchart showing a series of controls on the display area 30 when an operation on the scroll bar 32 in the display area 30 is executed. This series of controls is a display area when an operation is performed on the scroll bar 32 of the display area 30 that displays a plurality of options for inputting an operation instruction to the image processing apparatus 1 on the display unit 20a of the operation display unit 20. 30 control.

  Steps S202 to S210 shown in FIG. 7 are almost the same as steps S102 to S110 shown in FIG. Accordingly, steps S202 to S210 will be briefly described in the description of the series of controls for the display area 30 shown in FIG.

  First, when the display region 30 is in the initial state, the touch sensor unit 20b detects that an operation on the scroll bar 32 of the display region 30 displayed on the display unit 20a is performed using a touch pen or the like ( Step S201; Yes). When an operation on the scroll bar 32 is detected by the touch sensor unit 20b, the CPU 10 determines whether or not the display area 30 is an enlargement target area based on a predetermined determination criterion (step S202).

  When it is determined that the display area 30 is an enlargement target area (step S202; Yes), the display area 30 is enlarged by the instruction signal from the CPU 10 and scrolled in the enlarged state (step S203). . On the other hand, when it is determined that the display area 30 is not the enlargement target area (step S202; No), the display area 30 is scrolled without being enlarged (step S204).

  In step S203, after the display area 30 is scrolled in an enlarged state, it is determined whether any option displayed in the display area 30 has been selected (step S205).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S205; Yes). In response to the instruction signal from the CPU 10, the display area 30 enlarged in step S203 is returned to the initial size. Further, the display area 30 is controlled by the CPU 10 so that the selected option is displayed in the display area 30 returned to the initial state (step S206), and a series of controls on the display area 30 is completed.

  If selection of an option is not detected after the display area 30 is scrolled in the enlarged state in step S203 (step S205; No), an unrelated area 40 that is an area other than the display area 30 that is not related to selection of the option is displayed. It is determined whether or not it has been selected (step S207).

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (Step S207; Yes), and the display area 30 is returned to the initial state (Step S207). S208). And a series of control with respect to the display area 30 is complete | finished.

  Furthermore, if selection of the unrelated area 40 is not detected in step S207 (step S207; No), the process returns to step S205 again, and selection of an option (step S205) or selection of the unrelated area 40 (step S207) is detected. The monitoring state continues.

  On the other hand, when it is determined in step S202 that the display area 30 is not an enlargement target area (step S202; No), the display area 30 is scrolled without being enlarged (step S204), and then displayed in the display area 30. It is determined whether any of the selected options has been selected (step S209).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S209; Yes), and a series of controls for the display area 30 is completed.

  If selection of an option is not detected (step S209; No), it is determined whether or not the unrelated area 40 has been selected (step S210) as in step S207.

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (Step S210; Yes), and the series of controls for the display area 30 is completed.

  Furthermore, if selection of the unrelated area 40 is not detected in step S210 (step S210; No), the process returns to step S209 again, and selection of an option (step S209) or selection of the unrelated area 40 (step S210) is detected. The monitoring state continues.

  8A, 8B, and 8C are when the display area 30 is enlarged by an operation on the scroll bar 32, that is, when the display area 30 is determined to be an enlargement target area (FIG. 7). It is explanatory drawing which shows the change of the state of the display area 30 in middle step S202; refer to Yes).

  8A, 8 </ b> B, and 8 </ b> C, the display unit 20 a of the operation display unit 20 includes a display region 30 that displays a plurality of options and the like, and a region other than the display region 30 that is not related to selection of options. A non-related area 40 is displayed.

  The display area 30 includes a list display area 31 for displaying a plurality of options as a list, and a scroll bar 32 for executing a scroll operation. In the example shown in FIGS. 8A, 8B, and 8C, a list of destinations in facsimile communication or the like is displayed in the list display area 31, and each option represents a destination registered in advance. The scroll bar 32 has upper and lower arrows 32a and 32b provided at both ends of the scroll bar 32 and an area bar 32c provided between the upper and lower arrows 32a and 32b. The area bar 32c is provided with a knob 32d.

  In the non-related area 40, tab information such as TAB1 and TAB2 displayed above the display area 30 when the display area 30 is in the initial state, Home, and a message such as “Select Desired Destination.” Are displayed. For example, information that is not used when a specific option is selected from a plurality of options displayed in the list display area 31 of the display area 30, such as a message field for the message field.

  In the following, after the operation on the scroll bar 32 in the display area 30 is executed, the display area 30 is enlarged, and a specific option is selected from among a plurality of options displayed in the display area 30, thereby displaying the display area. A change in the state of the display area 30 until 30 is returned to the initial state will be described. The description of other changes in the state of the display area 30 is omitted because it is substantially the same as the description of the change in the state of the display area 30 when the display area 30 is enlarged by a flick operation or a drag operation.

  In FIG. 8A, when the display area 30 is in the initial state, nine options (registered destinations) from A1 to C3 are displayed in the form of 3 rows × 3 columns. In this initial state, an operation on the scroll bar 32 in the display area 30 is executed.

  Depressing one of the upper and lower arrows 32a and 32b of the scroll bar 32 (clicking, long pressing, etc.), dragging the knob 32d within the range of the region bar 32c, clicking or long pressing the region bar 32c When the scroll bar 32 is operated for some reason, as shown in FIG. 8B, the display area 30 is arranged in the longitudinal direction of the scroll bar 32, that is, in the vertical direction, at the upper end of the display screen of the display unit 20a. And expand to the bottom. In addition, the list display area 31 is expanded in the vertical direction together with the display area 30, and the scroll bar 32 extends in the vertical direction.

  When the display area 30 is enlarged in the vertical direction and is in an enlarged state, some information displayed in the unrelated area 40 is hidden by the enlarged display area 30. The hidden information includes tab information such as TAB1 and TAB2 displayed above the display area 30 in the initial state, a message field for displaying a message such as “Home” and “Select Desired Destination.”. And a Detail button displayed below the display area 30. These pieces of information are information that is not used when a specific option is selected from a plurality of options displayed in the list display area 31 of the display area 30, that is, information that is not related to the selection of the specific option. After the display area 30 is enlarged by an operation on the scroll bar 32 of the display area 30, when a specific option is selected from a plurality of options, the display unit 20a has a plurality of options and, if necessary, these options. It is only necessary to display accompanying information and the like, and tab information that is not related to selection of a specific option need not be displayed. Therefore, even if the display area 30 is enlarged so as to hide information that is not related to selection of options, the selection of options is not affected.

  When the display area 30 is in an enlarged state, the list display area 31 displays 15 options (registered destinations) from A1 to E3 in the form of 5 rows × 3 columns. In this enlarged state, option B2 (in the example of FIG. 8B, a transmission destination in facsimile communication or the like) corresponding to a desired operation instruction to the image processing apparatus 1 is selected.

  If the option B2 is selected when the display area 30 is in the enlarged state, the display area 30 is returned to the initial state as shown in FIG. That is, the enlarged display area 30 is reduced to the size before the operation on the scroll bar 32 is executed. In addition, the list display area 31 is reduced together with the display area 30, and the scroll bar 32 is shortened. Further, the reduced display area 30 is arranged at the same position as in FIG. Information hidden by the enlarged display area 30 such as tab information is displayed again as in FIG.

  When the display area 30 is returned to the initial state, the selected option B2 is displayed in the reduced list display area 31. In the example shown in FIG. 8C, when the display area 30 is returned to the initial state, the option B2 is displayed on the top line of the list display area 31. Furthermore, the information hidden when the display area 30 is in the enlarged state is displayed again on the display unit 20a.

  In FIG. 8C, when the display area 30 is returned to the initial state, the selected option B2 is displayed at the center of the top line of the reduced list display area 31, but the selected option is reduced. As long as the selected option is displayed in the list display area 31, the position where the selected option is displayed may be arbitrary.

  As described above, in the image processing apparatus 1 according to the embodiment, the touch sensor unit 20b of the operation display unit 20 detects a scroll operation on the display area 30 for displaying a plurality of options on the screen, and the CPU 10 Based on the detection result of the scroll operation, the display area 30 is expanded in the vertical direction, that is, along the scroll direction. Thereby, it is possible to suppress the number of scroll operations for the display area 30 until an option corresponding to a desired operation instruction is displayed in the display area 30 from among a plurality of options.

<Modification 1>
FIG. 9 is a flowchart showing a series of controls for the display area 30 according to the first modification.

  In the first modification, the speed of the flick operation or the speed of the drag operation is further detected in the series of controls on the display area 30 shown in FIG. 2, and the detection result of the speed of the flick operation or the speed of the drag operation is detected. A step of determining whether or not the display area 30 is enlarged is added.

  Steps S301 and S302 shown in FIG. 9 are substantially the same as steps S101 and S102 shown in FIG. Further, steps S304 to S311 shown in FIG. 9 are almost the same as steps S103 to S110 shown in FIG. Accordingly, steps S301, S302, and S304 to S311 will be briefly described in the description of the series of controls for the display area 30 shown in FIG.

  If the flick operation or the drag operation is detected by the touch sensor unit 20b when the display area 30 is in the initial state (step S301; Yes), the CPU 10 determines whether or not the display area 30 is the enlargement target area. (Step S302).

  When it is determined that the display area 30 is an enlargement target area (step S302; Yes), the process proceeds to step S303. On the other hand, when it is determined that the display area 30 is not the enlargement target area (step S302; No), the display area 30 is scrolled without being enlarged (step S304).

  After the display area 30 is determined to be an enlargement target area (step S302; Yes), the flick operation speed or the drag operation speed detected by the touch sensor unit 20b in step S301 is equal to or higher than a predetermined threshold by the CPU 10. Is determined (step S303).

  The speed of the flick operation is a moving speed of the touch pen or the like while the touch sensor unit 20b is in contact with the touch pen or the like during the flick operation. The drag operation speed is a moving speed of the touch pen or the like while the touch sensor unit 20b is in contact with the touch pen or the like during the drag operation.

  When the CPU 10 determines that the speed of the flick operation or the speed of the drag operation detected by the touch sensor unit 20b is equal to or higher than a predetermined threshold (step S303; Yes), the display area 30 is enlarged by an instruction signal from the CPU 10. Then, scrolling is performed in the enlarged state (step S305). On the other hand, when the CPU 10 determines that the flick operation speed or the drag operation speed is less than the predetermined threshold (step S303; No), the display area 30 is scrolled without being enlarged (step S304).

  The predetermined threshold may be appropriately set by the user according to the operability of the operation display unit 20. When the flick operation or the drag operation is executed a plurality of times, the speed of the first flick operation or the speed of the first drag operation may be compared with the predetermined threshold according to the operability of the operation display unit 20. Alternatively, a maximum value may be selected from the detected speeds of a plurality of flick operations or a plurality of drag operations, and the maximum value may be compared with the predetermined threshold value. For example, when the speed of the first flick operation is high and it is determined that the speed is equal to or higher than a predetermined threshold, the display area 30 is enlarged. In this case, the speed of the second and subsequent flick operations may not be compared with a predetermined threshold value. In addition, when the speed of the first flick operation is low and it is determined that the speed is less than the predetermined threshold, the display area 30 is not enlarged. When it is determined that the speed of the second flick operation is high and the speed is greater than or equal to a predetermined threshold, the display area 30 is expanded, and the speed of the flick operation for the third and subsequent times is equal to the predetermined threshold. It is not necessary to make a comparison.

  After the display area 30 is scrolled in an enlarged state in step S305, it is determined whether any option displayed in the display area 30 has been selected (step S306).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S306; Yes). In response to the instruction signal from the CPU 10, the display area 30 enlarged in step S305 is returned to the initial size (step S307). That is, the enlarged display area 30 is reduced to the size before the flick operation or the like is executed. Furthermore, the display area 30 is controlled by the CPU 10 so that the selected option is displayed in the display area 30 returned to the initial state, and a series of controls on the display area 30 is completed.

  If selection of an option is not detected after the display area 30 is scrolled in an enlarged state in step S305 (step S306; No), an unrelated area 40 that is an area other than the display area 30 that is not related to selection of the option is displayed. It is determined whether or not it has been selected (step S308).

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (Step S308; Yes), and the display area 30 is returned to the initial state (Step S308). S309). And a series of control with respect to the display area 30 is complete | finished.

  Furthermore, if selection of the unrelated area 40 is not detected in step S308 (step S308; No), the process returns to step S306 again, and selection of an option (step S306) or selection of the unrelated area 40 (step S308) is detected. The monitoring state continues.

  On the other hand, when it is determined in step S302 that the display area 30 is not the enlargement target area (step S302; No), or in step S303, it is determined that the flick operation speed or the drag operation speed is less than a predetermined threshold. In the case (Step S303; No), after the display area 30 is scrolled without being enlarged (Step S304), it is determined whether any of the options displayed in the display area 30 has been selected (Step S304). S310).

  When selection of an option is detected, the CPU 10 determines that one of the options has been selected (step S310; Yes), and a series of controls for the display area 30 is completed.

  If selection of an option is not detected (step S310; No), it is determined whether or not the unrelated area 40 is selected (step S311) as in step S308.

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (step S311; Yes), and the series of controls for the display area 30 is completed.

  Furthermore, if selection of the unrelated area 40 is not detected in step S311 (step S311; No), the process returns to step S310 again, and selection of an option (step S310) or selection of the unrelated area 40 (step S311) is detected. The monitoring state continues.

  In the first modification, it is determined whether the speed of the flick operation or the speed of the drag operation is equal to or higher than a predetermined threshold. When the speed is equal to or higher than the predetermined threshold, the display area 30 is enlarged, and when the speed is lower than the predetermined threshold The display area 30 is not enlarged. When the speed of the flick operation or the speed of the drag operation is high, the user usually tends to search for an option far from the scroll position when the flick operation or the like is executed. Since the display area 30 is scrolled larger, the necessity of enlarging the display area 30 to search for a desired option becomes higher. Conversely, when the speed of the flick operation or the speed of the drag operation is low, the user tends to search for a relatively close option in the list from the scroll position when the flick operation or the like is executed. If the scroll position is finely adjusted, it is often possible to search for a desired option, so that the necessity for enlarging the display area 30 becomes lower. Since it is determined whether or not to enlarge the display area 30 based on the speed of the flick operation or the like, the operability of the operation display unit 20 becomes higher. In addition, when the speed of the flick operation or the like is high, the scroll speed of the display area 30 is usually high. In the first modification, the display area 30 is enlarged along the scroll direction when it is determined that the speed of the flick operation or the like is equal to or higher than a predetermined threshold value. It becomes easier to follow the choices with your eyes.

<Modification 2>
FIG. 10 is a flowchart showing a series of controls for the display area 30 according to the second modification.

  In the second modification, a step of determining whether or not the display area 30 is enlarged based on the remaining scroll amount in the scroll direction is added to the series of controls for the display area 30 shown in FIG.

  Steps S401 and S402 shown in FIG. 10 are substantially the same as steps S101 and S102 shown in FIG. Further, steps S404 to S411 shown in FIG. 10 are almost the same as steps S103 to S110 shown in FIG. Therefore, steps S401, S402, and S404 to S411 will be briefly described in the description of the series of controls for the display area 30 shown in FIG.

  If a flick operation or a drag operation is detected by the touch sensor unit 20b when the display area 30 is in the initial state (step S401; Yes), whether or not the display area 30 is an enlargement target area is based on a predetermined determination criterion. (Step S402).

  When it is determined that the display area 30 is an enlargement target area (step S402; Yes), the process proceeds to step S403. On the other hand, when it is determined that the display area 30 is not the enlargement target area (step S402; No), the display area 30 is scrolled without being enlarged (step S404).

  After the display area 30 is determined to be an enlargement target area (step S402; Yes), the remaining scroll amount in the scroll direction is determined based on the scroll position of the display area 30 before the flick operation or the drag operation is executed. It is judged by CPU10 whether it is more than a predetermined threshold value (step S403).

  The remaining scroll amount in the scroll direction is the remaining scroll amount indicating how much the display area 30 can be further scrolled in the scroll direction from the scroll position when the flick operation or the like is executed.

  When the CPU 10 determines that the scroll remaining amount in the scroll direction is equal to or greater than the predetermined threshold, the display area 30 is enlarged by the instruction signal from the CPU 10 and scrolled in the enlarged state (step S405). On the other hand, when the CPU 10 determines that the remaining scroll amount in the scroll direction is less than the predetermined threshold (step S403; No), the display area 30 is scrolled without being enlarged (step S404).

  The predetermined threshold value may be appropriately set by the user according to the operability of the operation display unit 20, or may be set to a fixed value as a default value. For example, the predetermined threshold value may be set so that the display area 30 is not enlarged if the remaining scroll amount in the scroll direction is smaller than the scroll amount corresponding to the speed of the first flick operation. Further, if the scroll remaining amount is smaller than the length along the scroll direction of the display range (enlarged region) that should be added from the initial state of the display region 30 by the scroll operation, the display region 30 is not expanded. A predetermined threshold may be set.

  After scrolling in the state where the display area 30 is enlarged in step S405, it is determined whether any option displayed in the display area 30 has been selected (step S406).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S406; Yes). In response to the instruction signal from the CPU 10, the display area 30 enlarged in step S405 is returned to the initial size (step S407). That is, the enlarged display area 30 is reduced to the size before the flick operation or the like is executed. Furthermore, the display area 30 is controlled by the CPU 10 so that the selected option is displayed in the display area 30 returned to the initial state, and a series of controls on the display area 30 is completed.

  If selection of an option is not detected after the display area 30 is scrolled in an enlarged state in step S405 (step S406; No), an unrelated area 40 that is an area other than the display area 30 that is not related to selection of the option is displayed. It is determined whether or not it has been selected (step S408).

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (Step S408; Yes), and the display area 30 is returned to the initial state (Step S408). S409). And a series of control with respect to the display area 30 is complete | finished.

  Furthermore, if selection of the unrelated area 40 is not detected in step S408 (step S408; No), the process returns to step S406 again, and selection of an option (step S406) or selection of the unrelated area 40 (step S408) is detected. The monitoring state continues.

  On the other hand, when it is determined in step S402 that the display area 30 is not the enlargement target area (step S402; No), or when it is determined in step S403 that the remaining scroll amount in the scroll direction is less than the predetermined threshold (step S402). S403; No) After the display area 30 has been scrolled without being enlarged (step S404), it is determined whether any option displayed in the display area 30 has been selected (step S410).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S410; Yes), and a series of controls for the display area 30 is completed.

  If selection of an option is not detected (step S410; No), it is determined whether or not the unrelated area 40 is selected (step S411), as in step S408.

  When the selection of the unrelated area 40 is detected by the touch sensor unit 20b, the CPU 10 determines that the unrelated area 40 has been selected (step S411; Yes), and the series of controls for the display area 30 is completed.

  Furthermore, if selection of the unrelated area 40 is not detected in step S411 (step S411; No), the process returns to step S410 again, and selection of an option (step S410) or selection of the unrelated area 40 (step S411) is detected. The monitoring state continues.

  In Modification 2, it is determined whether or not the remaining scroll amount in the scroll direction is equal to or greater than a predetermined threshold value. When the remaining scroll amount is equal to or greater than the predetermined threshold value, the display area 30 is enlarged and the remaining scroll amount is less than the predetermined threshold value. When the display area 30 is not enlarged. When the scroll remaining amount is large, the display area 30 can be largely scrolled in the scroll direction from the scroll position when the flick operation or the like is executed. Therefore, it is more necessary to enlarge the display area 30 in order to search for a desired option. Conversely, when the scroll remaining amount is small, the display area 30 cannot be scrolled so much in the scroll direction from the scroll position when the flick operation or the like is executed. In this case, since there are few options that can be displayed by the scroll operation on the display area 30, it is less necessary to enlarge the display area 30. Since it is determined whether or not to enlarge the display area 30 based on the remaining scroll amount, the operability of the operation display unit 20 becomes higher.

<Modification 3>
FIG. 11 is a flowchart showing a series of controls for the display area 30 according to the third modification.

  In the third modification, instead of steps S107 and S110, a series of controls for the display area 30 shown in FIG. 2 are mainly performed after the enlarged state of the display area 30 continues for a predetermined time. In order to return to the state, a step of determining whether or not any operation is not performed on the display area 30 is continued for a predetermined time.

  Steps S501 to S506 shown in FIG. 11 are almost the same as steps S101 and S106 shown in FIG. Further, steps S508 and S509 shown in FIG. 11 are substantially the same as steps S108 and S109 shown in FIG. Accordingly, steps S501 to S506, S508, and S509 will be briefly described in the description of the series of controls for the display area 30 shown in FIG.

  If a flick operation or a drag operation is detected by the touch sensor unit 20b when the display area 30 is in the initial state (step S501; Yes), whether or not the display area 30 is an enlargement target area is based on a predetermined determination criterion. (Step S502).

  When it is determined that the display area 30 is an enlargement target area (step S502; Yes), the display area 30 is scrolled while being enlarged by an instruction signal from the CPU 10 (step S503). On the other hand, when it is determined that the display area 30 is not the enlargement target area (step S502; No), the display area 30 is scrolled without being enlarged (step S504).

  After scrolling in the state where the display area 30 is enlarged in step S503, it is determined whether any option displayed in the display area 30 has been selected (step S505).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S505; Yes). In response to the instruction signal from the CPU 10, the display area 30 enlarged in step S503 is returned to the initial size (step S506). That is, the enlarged display area 30 is reduced to the size before the flick operation or the like is executed. Furthermore, the display area 30 is controlled by the CPU 10 so that the selected option is displayed in the display area 30 returned to the initial state, and a series of controls on the display area 30 is completed.

  If selection of an option is not detected after the display area 30 is scrolled in the enlarged state in step S503 (step S505; No), whether or not any operation is not performed on the display area 30 for a predetermined time. Is determined by the CPU 10 (step S507).

  Some operation means a scroll operation such as a flick operation further performed on the display area 30 after the scroll of the display area 30 is stopped, selection of a desired option, and the like. The predetermined time may be appropriately set by the user according to the operability of the operation display unit 20.

  When it is determined that a state in which no operation is performed on the display area 30 has continued for a predetermined time (step S507; Yes), the display area 30 is returned to the initial state (step S508), and a series of operations on the display area 30 are performed. Control ends.

  On the other hand, when it is determined in step S502 that the display area 30 is not the enlargement target area (step S502; No), the display area 30 is scrolled without being enlarged (step S504) and then displayed in the display area 30. It is determined whether any of the selected options has been selected (step S509).

  When selection of an option is detected, the CPU 10 determines that any option has been selected (step S509; Yes), and a series of controls for the display area 30 is completed.

  If selection of an option is not detected after the display area 30 is scrolled in step S504 (step S509; No), the CPU 10 determines whether or not any operation is not performed on the display area 30 for a predetermined time. Determination is made (step S510).

  When it is determined that a state in which any operation is not performed on the display area 30 has continued for a predetermined time (step S510; Yes), a series of controls on the display area 30 ends.

  In the third modification, when the display area 30 is in the enlarged state, it is determined whether or not any operation is not performed on the display area 30 for a predetermined time. When it is determined that a state in which no operation is performed on the display area 30 has continued for a predetermined time, the display area 30 is returned to the initial state. Accordingly, the standby state until a desired option is selected from a plurality of options while the display area 30 is in an enlarged state is not wasted.

  Regarding the process of step S303 in modification 1, the process of step S403 in modification 2, and the process of step S507 in modification 3, two or more of these processes are shown in FIG. 2, which is a basic example of the present embodiment. It may be appropriately incorporated into the series of controls shown.

  As mentioned above, although embodiment of this invention and each modification were demonstrated with drawing, specific structure is not restricted to what was shown in embodiment, In the range which does not deviate from the summary of this invention, Any additions are included in the present invention.

  In the present embodiment, when a scroll operation is performed on the display area 30, the display area 30 is enlarged in the direction parallel to the scroll direction, that is, upward and downward. When the display area 30 is scrolled upward, the display area 30 may be enlarged only in the upward direction. When the display area 30 is scrolled downward, the display area 30 may be enlarged only in the downward direction.

  In the present embodiment, the case where the scroll direction of the display area 30 is the upward direction or the downward direction has been described. However, when the display area 30 is scrolled leftward or rightward, the display area 30 is horizontally May be expanded. When the display area 30 is scrolled to the left, the display area 30 is enlarged only in the left direction. When the display area 30 is scrolled to the right, the display area 30 is enlarged only in the right direction. May be. In addition, when the display area 30 is scrolled in an oblique direction (a direction other than the horizontal direction or the vertical direction), the display area 30 may be enlarged in the vertical direction and the horizontal direction. Since the display area 30 is expanded in the vertical direction and the horizontal direction, as a result, the display area 30 is expanded in an oblique direction that is the scroll direction of the display area 30.

  Moreover, in this Embodiment, when scroll operation is performed with respect to the display area 30 to the upper direction or the downward direction, the display area 30 was expanded to the upper end and lower end of the display screen of the display part 20a. However, the display area 30 does not need to be expanded to both ends of the display screen of the display unit 20a in the direction along the scroll direction, and the expansion range of the display area 30 is determined according to the operability of the operation display unit 20. Also good.
