Description

  The present invention relates to a display data scroll device for scrolling display data in an information display device, a display data scroll method, a display data scroll program, and a program recording medium.

  Conventionally, when scrolling display data in an information display device, as can be seen on a personal computer, a line or line is displayed by a scroll bar displayed at the edge of the screen and an indicator indicating the current position of displayed data with respect to all data. There is a method of scrolling page by page. In this method, a method of scrolling in the scroll direction in dot units is also implemented.

  Further, as an improvement method for the display data scrolling method, there is a method disclosed in Patent Document 1. In the screen scroll control method disclosed in Patent Document 1, a first scroll area composed of four step scroll areas is provided at the four-direction ends of the edit screen in the four directions of up, down, left, and right, and the four directions of up, down, left, and right in the edit screen. A second scroll area including four smooth scroll areas is provided at the end. When the step scroll area is selected with the mouse button, the scroll is performed in units of 1 block of n rows and m columns. When the smooth scroll area is clicked with the mouse button, the unit is scrolled in units of 1 row and 1 column. Scrolling is performed. Further, the cursor shape is made different between the step scroll area and the smooth scroll area so that the operator can confirm which of the step scroll area and the smooth scroll area is selected. Thus, the operability at the time of display data scrolling is improved and the display area is prevented from being reduced.

  However, the scroll method using the conventional scroll bar and the indicator and the screen scroll control method disclosed in the cited document 1 have the following problems.

  That is, the former scroll method is currently widely used in personal computers, and can be scrolled with little stress on the user. The latter screen scroll control method is very convenient because it improves operability and display area.

However, in both cases, it is assumed that the data is temporarily implemented on a personal computer that can access data at high speed, and the amount of data to be handled at a time increases. For this reason, a high processing capacity of a CPU (central processing unit) and a large amount of data can be accelerated at a high speed at a time, and a random access memory (RAM) is required, which makes the system large. Therefore, there is a problem that the CPU with low processing capability currently used in portable devices and the like has insufficient processing capability and cannot be applied to portable information devices and the like.

The first scroll for scrolling the displayed part of the data at the predetermined interval according to the first scroll, and the part of the displayed data scrolled at an interval smaller than the predetermined interval according to the operation command of the second scroll bar. Since the second scroll is configured, the first scroll at a predetermined interval and the predetermined scroll when displaying the desired stored data. By the second scroll at an interval smaller than interval can be narrowed down stepwise desired storage data.

  Therefore, scrolling can be executed stepwise mainly only by software support, and it is not necessary for a RAM for separately storing a large amount of data, and is a case of a CPU of a portable terminal device having a relatively low processing capability. However, it is possible to perform scrolling without giving stress to the user.

  In addition, the first and second scroll bars operated by the user can change the relative position of the first scroll with respect to all data and the relative position of the second scroll with respect to the divided area including a part of the displayed data. Can be displayed. Thus, by displaying the current search position in stages, the search efficiency can be improved and the convenience for the user can be improved.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. Here, a case will be described in which the present invention is applied to a portable terminal device in which a large-scale system cannot be constructed.

-1st Embodiment FIG. 1: is a functional block diagram which shows the functional structure regarding the scroll display in the portable terminal device by which the display data scroll apparatus of this Embodiment is mounted. This portable terminal device is configured on a simple computer and includes an input unit 1, a storage unit 2, a scroll processing unit 3, and a display unit 4.

  The input unit 1 includes a keyboard and a mouse, and an operation command, a set value, and the like described later are input by a user. Then, the operation command and the set value input from the input unit 1 are output to the scroll processing unit 3. The storage unit 2 stores data used by being displayed on the display unit 4 such as document data and meeting minutes. When the display data displayed on the display unit 4 cannot fit into the display screen, the scroll processing unit 3 scrolls the display data according to an operation command from the input unit 1. In this case, the scroll processing unit 3 has a function of scrolling by switching the scroll interval to two stages according to the operation command. The first scroll processing unit 3a performs rough scrolling at a larger scroll interval, and the second scroll processing unit 3b executes scrolling for each line at a smaller scroll interval. In addition to the display data, the display unit 4 includes a scroll bar operated by the operation command, an indicator indicating all data to be displayed, the scroll interval, and a pointer relatively indicating a scroll position with respect to the scroll interval. Is displayed.

  FIG. 2 is a block diagram showing a hardware configuration of the mobile terminal device having the functional configuration of FIG. The portable terminal device includes a CPU 5 that performs overall control, and a rewritable ROM (read only memory) (for example, EPROM (ultraviolet erasable ROM)) in which a program for operating the CPU 5 is stored. 6. RAM 7 used for temporarily storing display data or used as a work memory of CPU 5, display device 8 including a liquid crystal display device for displaying data stored in RAM 7 and various setting contents, data input and various types An input device 9 for inputting settings and a clock 10 are provided. Note that a communication I / F connected to a communication network such as the Internet, an external auxiliary storage device in which an external recording medium is set and accesses the external recording medium may be further provided.

  That is, the input unit 1 is configured by the input device 9, the storage unit 2 is configured by the RAM 7, the scroll processing unit 3 is configured by the CPU 5, and the display unit 4 is configured by the display device 8. In addition to the processing operation according to the present embodiment by the scroll processing unit 3 described above, the CPU 5 also performs various processing operations such as calculation / determination processing, timing processing, and input / output processing.

  Hereinafter, this embodiment will be described with reference to FIG. FIG. 3 shows a display example of the display data displayed on the display device 8 under the control of the CPU 5. In the display device 8, a part 11 of stored data stored in the RAM 7, a first scroll bar 12 and a second scroll bar 13 for executing scrolling step by step, and all data to be displayed are displayed. An indicator 14 indicating the number of lines and the number of lines in the first scroll unit group (described later) is displayed. Here, the second scroll bar 13 also has a function as a pointer indicating the second scroll position with respect to the entire unit group of the first scroll. Further, the first scroll bar 12 has a function as an indicator that indicates the number of lines in the unit group of the first scroll relative to the number of lines of the above-described all data indicated by the length of the indicator 14, and the indicator 14. And a function as a pointer indicating the first scroll position with respect to all the data at the relative position.

  FIG. 4 is a flowchart showing the display data scroll processing operation executed under the control of the CPU 5. FIG. 5 is a diagram showing a state of stored data stored in the RAM 7. The display data scroll processing operation will be described below with reference to FIGS.

  When the user presses the “ON” key in the input device 9 shown in FIG. 2 to input an “ON” signal to the CPU 5, the display data scroll processing operation starts.

  In step S1, a part of the data stored in the RAM 7 is displayed on the display device 8. As a result, an arbitrary portion 21 of the data stored in the RAM 7 shown in FIG. 5 is displayed on the display device 8 together with the first scroll bar 12 and the second scroll bar 13 as shown in FIG. In step S <b> 2, the first scroll bar 12 is selected by the user from among the scroll bars displayed on the display device 8 by the user. In step S3, the moving direction of the selected first scroll bar 12 is determined by the user, and when the first scroll bar 12 is operated in the moving direction by the input device 9, the first scroll of display data is started. .

  Here, in the operation by the operation of the first scroll bar 12, the stored data located at the head portion of the unit group is sequentially displayed for each predetermined unit group. The numerical values of the predetermined unit group are stored in the ROM 6 as scroll interval setting values. Therefore, in step S4, the CPU 5 reads the scroll interval setting value from the ROM 6. For example, if the scroll interval setting value is “100 lines” as shown in FIG. 5, “100 lines” are read from the ROM 6. In step S5, the first scroll is performed once, and the line in which the scroll interval set value (100 lines in the case of FIG. 5) is added to the first line of the arbitrary portion 21 displayed before the scroll is set as the head. Stored data for a predetermined number of lines (two lines in the case of FIG. 5) from the top in the portion 22 to be displayed is displayed.

  In addition, in FIG. 3, the display position relative to the indicator 14 of the first scroll bar 12 is moved by 100 lines. Thus, the relative amount of the first scroll unit group with respect to all display data and the current first scroll position can be intuitively grasped by the length of the first scroll bar 12 and the relative position with respect to the indicator 14. It can be done.

  In step S6, it is determined whether or not to end the first scroll. As a result, if the process is to end, the process proceeds to step S7. On the other hand, if not finished, the process returns to step S2 to continue the first scroll, and the process shifts to the display of the stored data in the portion 23 in FIG. Here, the method for determining whether or not to end the first scroll is not particularly limited. For example, it can be determined that the first scroll bar 12 is not selected for a predetermined time or more. Alternatively, it may be performed by displaying a confirmation dialog and responding thereto. Thus, the steps S2 to S6 are repeated in order to retrieve the desired stored data by the user, and when the scroll is performed to the vicinity of the desired stored data, the execution of the first scroll is finished. It is.

  In step S7, the input device 9 selects the second scroll bar 13 displayed on the display device 8 together with the stored data. In step S8, the moving direction of the selected second scroll bar 13 is determined by the user, and when the second scroll bar 13 is operated in the moving direction by the input device 9, the second scrolling of the display data is started. In step S9, the second scroll is performed once, and the stored data of the portion 24 starting from the row in which one row is added to the first row of the arbitrary portion 21 displayed before the scroll is displayed.

  At the same time, in FIG. 3, the relative display position of the second scroll bar 13 with respect to the indicator 14 indicating the number of lines of the first scroll unit group is moved by one line. Thus, the current second scroll position can be intuitively grasped by the relative position of the second scroll bar 13 to the indicator 14.

  In step S10, it is determined whether or not to end the second scroll. As a result, when it ends, the process proceeds to step S11, and when it does not end, the process returns to step S7 and the second scroll is continued. Here, the method for determining whether or not to end the second scroll is not particularly limited. For example, the second scroll bar 13 is not selected for a predetermined time or more. Here, in the second scroll, all stored data in the unit group of the first scroll is displayed line by line. For example, as shown in FIG. 5, if the unit group of the first scroll is “100 lines”, the stored data for 100 lines are displayed line by line. Accordingly, by continuing to operate the second scroll bar 13, the stored data for the unit group of the first scroll is sequentially displayed up to the last line. In this case, the number of lines in the unit group of the first scroll indicated by the length of the indicator 14 represents “100 lines”.

  In step S11, it is determined whether or not to end the display data scroll processing operation. If the target storage data can be retrieved, the display data scroll processing operation is terminated. On the other hand, if the search is not completed or if the next data needs to be searched, the process returns to step S2 and the display data scroll processing operation is continued.

  As described above, in the present embodiment, the stored data stored in the RAM 7 is operated by operating the first scroll bar 12 and the second scroll bar 13 to roughly define the first data for each unit group. When scrolling is performed and a unit group in which desired data is present is displayed, the second scroll is performed for each row of stored data in the unit group. Therefore, the data to be displayed can be narrowed down step by step only by the correspondence of the software as shown in FIG. 4, and even if the CPU 5 has a low processing capacity, the display data can be scrolled without imposing a load. .

  Further, in the stepwise scroll, the relative amount of the first scroll unit group with respect to all data to be searched, the relative position of the first scroll with respect to the entire data, and the second scroll with respect to the first scroll unit group. The relative position can be displayed simultaneously. Therefore, the user interface and search efficiency can be improved, and the user can easily browse the target data.

Second Embodiment The functional block diagram and block diagram of the mobile terminal device in the present embodiment are the same as those in FIGS. 1 and 2 in the first embodiment. Hereinafter, FIG. 2 will also be used in the description of the portable terminal device in the present embodiment. The difference between the present embodiment and the first embodiment is that the RAM 7 has a size corresponding to the display capability (display size) of the display device 8 and stores a plurality of independent data. Yes. In the display data scroll processing operation, the data stored in the RAM 7 is displayed and scrolled in independent individual data units.

  In the case of the first embodiment, in the first scroll operation, only the stored data located at the head portion of the unit group is sequentially displayed for each predetermined unit group. . Therefore, the data stored in the RAM 7 may be continuous data as shown in FIG. 5 or a set of individual independent data, but for each unit group (100 rows in the case of FIG. 5). Are displayed line by line. As a result, in the case of data that is independent from each other by date, such as the minutes of a meeting, the display may be interrupted in the middle of one minutes when scrolling once, which is inconvenient. is there. On the other hand, in the case of the present embodiment, the stored data is independent data collected in a certain unit (for example, date, year, etc.). Since only the data located at the head is sequentially displayed for each predetermined data group (for example, every 20 data), the inconvenience as described above is eliminated.

  FIG. 6 shows a display example of the display data displayed on the display device 8. In the display device 8, a part 31 of the stored data, the first scroll bar 32 and the second scroll bar 33 for executing scrolling step by step, the number of data of all data to be displayed, and the first An indicator 34 indicating the number of data in one scroll data group is displayed. Here, the second scroll bar 33 also has a function as a pointer indicating the second scroll position with respect to the entire first scroll data group. Further, the first scroll bar 32 has a function as an indicator that indicates the number of data of the first scroll data group relative to the number of all the data indicated by the length of the indicator 34, and the indicator 34 And a function as a pointer indicating the first scroll position with respect to all the data at the relative position.

  FIG. 7 is a flowchart showing a display data scroll processing operation executed under the control of the CPU 5. FIG. 8 is a diagram showing the state of stored data stored in the RAM 7. The display data scroll processing operation will be described below with reference to FIGS.

  When the user presses the “ON” key in the input device 9 shown in FIG. 2 to input an “ON” signal to the CPU 5, the display data scroll processing operation starts.

  In steps S21 to S26, as in steps S1 to S6 of the display data scroll processing operation shown in FIG. 4 in the first embodiment, a part of the data stored in the RAM 7 is displayed, and the first scroll bar 32 is displayed. Selection, determination of the scroll direction and start of the first scroll, reading of the scroll interval setting value, display of the data after scrolling, and determination of the end of the first scroll.

  Here, in the above step S21, for example, as shown in FIG. 8, when the minutes data of the independent internal meeting is stored in the RAM 7 for each date, arbitrary data 41 is displayed. Further, the scroll interval setting value read from the ROM 6 by the CPU 5 in the step S24 is the number of independent data as described above. That is, in the case of FIG. 8, the number of data “20” is read as the scroll interval setting value. In the display of the post-scrolling data in step S25, as shown in FIG. 8, the data obtained by integrating the scroll interval set value (20 pieces) with the data number “20” of the arbitrary data 41 displayed before the scrolling. Only the top data 42 of the data group consisting of 20 data starting from the data 42 with the number “40” is displayed.

  At the same time, in FIG. 6, the display position relative to the indicator 34 of the first scroll bar 32 is moved by 20 data. Thus, the relative amount of the first scroll data group with respect to all display data and the current first scroll position can be intuitively grasped by the length of the first scroll bar 32 and the relative position with respect to the indicator 34. It can be done.

  When the vicinity of the desired stored data is displayed in steps S21 to S26, the first scroll is finished and the process proceeds to step S27. In step S27 to step S31, as in step S7 to step S11 of the display data scroll processing operation shown in FIG. 4 in the first embodiment, selection of the second scroll bar 33, determination of the scroll direction, and second scrolling are performed. Start, display of data after scrolling, end determination of the second scroll, and end determination of the display data scroll processing operation are performed.

  Here, in the operation in the second scroll, all stored data in the data group displayed as a result of the first scroll are sequentially displayed in data units. Therefore, in the data display after the second scroll executed in step S29, only the next stored data in the data group displayed as a result of the first scroll is displayed. For example, as shown in FIG. 8, when the scroll interval setting value of the first scroll is “20”, the next data of the display data 41 among the 20 data in the currently displayed data group. 43 is displayed. Then, by continuing to operate the second scroll bar 33, “20” data, which is the data group of the first scroll, is sequentially displayed up to the final data.

  At the same time, in FIG. 6, the relative display position of the second scroll bar 33 with respect to the indicator 34 indicating the number of data in the first scroll data group is moved by one piece of data. Thus, the current second scroll position can be intuitively grasped by the relative position of the second scroll bar 33 with respect to the indicator 34. In this case, the length of the indicator 34 indicates the number of data of the data group on which the second scroll is performed, not the number of data of all data to be displayed.

  As described above, in the present embodiment, the stored data stored in the RAM 7 is operated by operating the first scroll bar 32 and the second scroll bar 33 to roughly define the first data for each predetermined data group. When scrolling is performed and a data group in which desired data exists is displayed, the second scroll is performed for each piece of stored data in the data group. Therefore, the data to be displayed can be narrowed down step by step only by the correspondence of software as shown in FIG. 7, and even if the CPU 5 has a low processing capacity, the display data can be scrolled without imposing a load. .

  Further, in the above-described stepwise scrolling, for example, data stored independently of each other in date units, such as meeting minutes, is scrolled in individual data units. Therefore, the individual data is not displayed in the middle of the scrolling, and the convenience for the user can be improved.

Third Embodiment The functional block diagram of the mobile terminal device in the present embodiment is basically the same as FIG. 1 in the first embodiment. The block diagram of the portable terminal device is the same as that in FIG. 2 in the first embodiment. Hereinafter, FIG. 2 will also be used in the description of the portable terminal device in the present embodiment. The difference between the present embodiment and the first embodiment is that in the display data scroll processing operation, the scroll method in the first embodiment is the same as the row direction and the column direction of the display data displayed on the display device 8. It can be executed in two directions. Hereinafter, the row direction may be referred to as a horizontal direction, and the column direction may be referred to as a vertical direction.

  That is, in the functional block diagram of the mobile terminal device in the present embodiment, the scroll processing unit 3 includes the above-described first and second scroll processing units 3a and 3b for performing scrolling in the vertical direction. There are provided third and fourth scroll processing units for scrolling in the horizontal direction.

  FIG. 9 shows a display example of the display data displayed on the display device 8. In the display device 8, a part 51 of stored data stored in the RAM 7 and a first scroll having exactly the same functions as the first scroll bar 12, the second scroll bar 13 and the indicator 14 in the first embodiment. A bar 52, a second scroll bar 53, and an indicator 54 are displayed. Further, a third scroll bar 55, a fourth scroll bar 56, and an indicator 57 for performing stepwise scrolling in the row direction of the display data are displayed in the lower part of the display area of the display data 51 in the figure. . Hereinafter, the indicator 54 is referred to as a first indicator, and the indicator 57 is referred to as a second indicator.

  Here, the fourth scroll bar 56 also has a function as a pointer indicating the fourth scroll position with respect to the entire unit group of the third scroll. The third scroll bar 55 has a function as an indicator that indicates the number of columns of the unit group of the third scroll relative to the number of columns of all the data indicated by the length of the indicator 57, and the indicator 57 And a function as a pointer indicating the third scroll position for all the data at the relative position. Here, the third scroll means a coarse scroll in the row direction of the display data, and the fourth scroll means a fine scroll in the row direction.

  FIG. 10 is a diagram showing a state of stored data stored in the RAM 7. However, FIG. 10 is a data state diagram when the first scroll is executed every 200 rows in the vertical direction and the third scroll is executed every 50 columns in the horizontal direction in the present embodiment. It is. Here, 61, 62, and 63 indicate the movement state of the display target portion of the stored data when the first and third scrolls are performed once.

  Note that the vertical display data scroll processing operation in the present embodiment is exactly the same as the display data scroll processing operation shown in FIG. 4 in the first embodiment. However, the vertical scroll interval setting value is 200 lines. The horizontal display data scroll processing operation in the present embodiment is substantially the same as the display data scroll processing operation shown in FIG. 4 in the first embodiment. However, it is necessary to replace the first scroll bar 12 with the third scroll bar 55 and replace the second scroll bar 13 with the fourth scroll bar 56. The horizontal scroll interval setting value is 50 columns.

  Here, as can be seen from FIG. 10, the vertical scroll and the horizontal scroll need to be able to move to each other at a certain point in time. In the present embodiment, the transition point between the vertical scroll and the horizontal scroll is not particularly limited. However, for example, after the scrolling in the vertical direction is finished, it is possible to shift to the scrolling in the horizontal direction even when the vertical scrolling is being executed. Moreover, it does not matter whether it starts from either scrolling in the vertical direction or scrolling in the horizontal direction.

  For example, when the first and second scrolls are finished in the vertical direction, it is common to shift to the third scroll in the horizontal direction, and then execute the fourth scroll in the horizontal direction. Alternatively, when the first scroll is completed in the vertical direction, the process proceeds to the third scroll in the horizontal direction, and when the third scroll is completed in the horizontal direction, the process proceeds to the second scroll in the vertical direction. When the two scrolls are completed, the fourth scroll in the horizontal direction may be shifted. In addition, when the horizontal unit group in which desired data exists is displayed during execution of the first scroll in the vertical direction, the third scroll in the horizontal direction may be omitted.

  As described above, in the present embodiment, the display data displayed on the display device 8 is scrolled in two directions, the row direction and the column direction. Therefore, as shown in FIG. 10, even when the size of the data stored in the RAM 7 in the row direction and the column direction is larger than the vertical display size and the horizontal display size of the display device 8. , Scrolling can be performed in the above-mentioned steps in each direction. Therefore, even in a portable terminal device in which the display size of the display device 8 is limited, desired data can be easily browsed.

-4th Embodiment The functional block diagram of the portable terminal device in this Embodiment is fundamentally the same as FIG. 1 in the said 1st Embodiment. The block diagram of the portable terminal device is the same as that in FIG. 2 in the first embodiment. Moreover, the display example of the display data displayed on the display device 8 is the same as FIG. 3 in the first embodiment. Hereinafter, FIG. 2 and FIG. 3 will also be used in the description of the portable terminal device in the present embodiment.

  The difference between the present embodiment and the first embodiment is that the scroll interval setting value can be set from the outside in the display data scroll processing operation. By doing so, it is possible to appropriately change the number of rows in the unit group when performing the first scroll in the first embodiment according to the convenience and circumstances of the user.

  That is, in the functional block diagram of the mobile terminal device according to the present embodiment, a scroll interval changing unit that changes the scroll interval according to the set value from the input unit 1 is newly provided.

  FIG. 11 is a flowchart showing a display data scroll processing operation executed under the control of the CPU 5. The display data scroll processing operation will be described below with reference to FIGS.

  When the user presses the “ON” key in the input device 9 shown in FIG. 2 to input an “ON” signal to the CPU 5, the display data scroll processing operation starts.

  In step S41, it is determined whether or not to change the scroll interval, which is the number of unit lines of the first scroll. As a result, if it is changed, the process proceeds to step S42, and if not changed, the process proceeds to step S44. Here, the change of the scroll interval is determined by, for example, a response from the user to the displayed confirmation dialog.

  In step S42, the user operates the input device 9 to input a scroll interval setting value. In this case, it is assumed that “200 lines” is input as the scroll interval setting value. In step S43, the scroll interval setting value registered in the ROM 6 is rewritten by the input scroll interval setting value "200 lines".

  In steps S44 to S49, as in steps S1 to S6 of the display data scroll processing operation shown in FIG. 4 in the first embodiment, a part of the data stored in the RAM 7 is displayed, and the first scroll bar 12 is displayed. Selection, determination of the scroll direction and start of the first scroll, reading of the scroll interval setting value, display of the data after scrolling, and determination of the end of the first scroll. However, in step S47, the scroll interval set value “200 lines” is read out in step S43. Further, the display of the post-scrolling data in step S48 is performed every "200 lines". Further, the movement of the display position of the first scroll bar 12 is as described in the first embodiment.

  In steps S50 to S54, the selection of the second scroll bar 13, the determination of the scroll direction, and the second scrolling are performed in the same manner as in steps S7 to S11 of the display data scroll processing operation shown in FIG. 4 in the first embodiment. Start, display of data after scrolling, end determination of the second scroll, and end determination of the display data scroll processing operation are performed. Thus, all stored data in the unit group displayed as a result of the first scroll is sequentially displayed in units of rows.

  As described above, in the present embodiment, the number of lines in the unit group in the first scroll can be appropriately changed by the user. Therefore, the user can browse desired data more easily.

  Note that the change of the scroll interval setting value in the present embodiment can also be applied to the vertical scroll and the horizontal scroll in the third embodiment.

-5th Embodiment The functional block diagram of the portable terminal device in this Embodiment is fundamentally the same as FIG. 1 in the said 1st Embodiment. The block diagram of the portable terminal device is the same as that in FIG. 2 in the first embodiment. Hereinafter, FIG. 2 will also be used in the description of the portable terminal device in the present embodiment. The difference between the present embodiment and the first embodiment is that the number of stages of narrowing scrolling when performing narrowing scrolling in stages in the display data scroll processing operation can be set from the outside. In this way, more detailed scrolling is possible.

  That is, in the functional block diagram of the mobile terminal device in the present embodiment, the scroll processing unit 3 is provided with a first scroll processing unit to an n-th scroll processing unit according to the number n of scroll stages. Further, a scroll stage number changing unit is provided for changing the number of scroll stages according to the set value from the input unit 1.

  FIG. 12 shows a display example of the display data displayed on the display device 8. In the display device 8, a part 71 of stored data stored in the RAM 7 and a scroll bar and an indicator corresponding to the number of stages of narrowing scroll are displayed. FIG. 12 shows a display example when the narrowed scroll is performed in three stages. The first scroll bar 72, the second scroll bar 73 and the third scroll bar 74 for executing the scroll in stages, and the display target A first indicator 75 indicating the number of all data lines and the number of lines in the first scroll unit group, and a second indicator 76 indicating the number of lines in the second scroll unit group are displayed.

  Here, the third scroll bar 74 also has a function as a pointer indicating the third scroll position with respect to the entire unit group of the second scroll. The second scroll bar 73 is an indicator that indicates the number of lines in the second scroll unit group relative to the number of lines in the first scroll unit group indicated by the length of the first indicator 75. And a function as a pointer indicating the second scroll position with respect to the entire unit group of the first scroll at a position relative to the first indicator 75. The first scroll bar 72 has a function as an indicator that indicates the number of lines of the first scroll unit group relative to the number of lines of the entire data indicated by the length of the first indicator 75. And a function as a pointer indicating the first scroll position for all the data at a position relative to one indicator 75.

  Here, the number of lines in each scroll unit group is set in advance according to the number of stages of scrolling, and is stored and registered in the ROM 6 or the like. When the number of scroll stages is designated by the user from the input device 9, the CPU 5 reads out the number of lines in each scroll unit group according to the designated number of stages, and the first and second indicators 75, 76 The display length and the display lengths of the first and second scroll bars 72 and 73 are calculated. Then, according to the calculation result, the display device 8 displays the scroll bars 72 to 74 and the indicators 75 and 76 together with a part 71 of the stored data.

  13 and 14 are flowcharts showing the display data scroll processing operation executed under the control of the CPU 5. Hereinafter, the display data scroll processing operation will be described with reference to FIGS. 2, 12, 13 and 14.

  When the user presses the “ON” key in the input device 9 shown in FIG. 2 to input an “ON” signal to the CPU 5, the display data scroll processing operation starts.

  In step S61, it is determined whether or not to change the number of stages of scrolling. As a result, if it is changed, the process proceeds to step S62, and if not changed, the process proceeds to step S64. Here, the determination of the change in the number of steps is performed by, for example, a response from the user to the displayed confirmation dialog.

  In step S62, the user operates the input device 9 to input a scroll stage number setting value. In this case, it is assumed that “3” is input as the scroll stage number setting value. In step S63, the scroll stage number setting value registered in the ROM 6 is rewritten by the input scroll stage number setting value "3".

  In steps S64 to S69, as in steps S1 to S6 of the display data scroll processing operation shown in FIG. 4 in the first embodiment, a part of the data stored in the RAM 7 is displayed, and the first scroll bar 72 is displayed. Selection, determination of the scroll direction and start of the first scroll, reading of the scroll interval setting value, display of the data after scrolling, and determination of the end of the first scroll.

  Here, the description in the flowcharts shown in FIGS. 13 and 14 is omitted because it is complicated, but at the stage where the scroll stage number setting value is written in step S63, the scroll stage number setting value (number of stages) is omitted. The number of lines (scroll interval setting value) of each scroll unit group corresponding to the value is read from the ROM 6 and stored in the RAM 7, and the display length of each indicator 75, 76 and the display length of each scroll bar 72, 73 are determined. Calculated. When a part of the stored data is displayed in step S64, the scroll bars 72, 73, 74 and the indicators 75, 76 are displayed simultaneously according to the calculated length.

  In step S67, the scroll interval setting value for the first scroll (for example, 100 rows) read from the ROM 6 or the like and stored in the RAM 7 is read. Further, the movement of the display position of the first scroll bar 72 is as described in the first embodiment.

  In steps S70 to S74, the selection of the second scroll bar 73, the determination of the scroll direction and the second scroll are performed in the same manner as in steps S2 to S6 of the display data scroll processing operation shown in FIG. 4 in the first embodiment. The start, the reading of the scroll interval setting value, the display of the data after scrolling, and the end of the second scroll are determined. Here, in step S72, the scroll interval setting value (for example, 20 lines) for the second scroll stored in the RAM 7 is read. Further, the movement of the display position of the second scroll bar 73 is as described in the first embodiment.

  In steps S75 to S79, the selection of the third scroll bar 74, the determination of the scroll direction, and the third scrolling are performed in the same manner as in steps S7 to S11 of the display data scroll processing operation shown in FIG. 4 in the first embodiment. Start, display of data after scrolling, end determination of the third scroll, and end determination of the display data scroll processing operation are performed. Thus, all stored data in the unit group displayed as a result of the second scroll is sequentially displayed in units of rows.

  Here, the flowchart of the display data scroll processing operation shown in FIGS. 13 and 14 is a flowchart dedicated to the scroll stage setting value “3”. Thus, the ROM 6 may store a dedicated display data scroll program for each scroll stage setting value. Alternatively, in the case of the flowchart showing the display data scroll processing operation shown in FIGS. 13 and 14, steps S65 to S69 and steps S70 to S74 are the scroll bar to be selected and the scroll to be read. The only difference is the interval setting value, which is substantially the same. Therefore, the ROM 6 stores a display data scroll program including steps S61 to S69 and steps S75 to S79, and the number of times (for example, “3”) corresponding to the input scroll setting value (for example, “3”). Steps S65 to S69 may be repeated only “twice”. In this way, the storage capacity of the display data scroll program can be reduced.

  As described above, in the present embodiment, the number of narrowing stages when performing narrowing scrolling in stages can be changed as appropriate by the user. Therefore, the user can narrow down desired data accurately and easily browse even when the stored data stored in the RAM 7 is very large.

  Note that the change in the scroll stage number setting value in the present embodiment can also be applied to the vertical scroll and horizontal scroll in the third embodiment.

  Further, in each of the above embodiments, the scroll interval in the last stage scroll when the scrolling is performed in stages is set to one row or one column. However, the present invention is not limited to this, and the transition may be made even if it is appropriately changed according to the situation.

  By the way, the functions as the scroll processing unit 3, the scroll interval changing unit, and the scroll stage number changing unit in the embodiment are realized by a display data scroll program recorded in a program recording medium. The program recording medium in each of the above embodiments is a program medium composed of the ROM 6. Alternatively, it may be a program medium that is loaded into the external auxiliary storage device and read out. In any case, the program reading means for reading the display data scroll program from the program medium may have a configuration for directly accessing and reading the program medium, or a program storage area (see FIG. (Not shown) may be downloaded, and the program storage area may be accessed and read. It is assumed that a download program for downloading from the program medium to the program storage area of the RAM 7 is stored in advance in the main unit.

  Here, the program medium is configured to be separable from the main body side, and is a tape system such as a magnetic tape or a cassette tape, a magnetic disk such as a floppy disk or a hard disk, a CD (compact disk) -ROM, or MO (magneto-optical). Optical discs such as discs, MD (mini discs) and DVDs (digital versatile discs), card systems such as IC (integrated circuit) cards and optical cards, mask ROM, EPROM (ultraviolet erasable ROM), EEPROM (electrical This is a medium that carries a fixed program, including a semiconductor memory system such as a static erasable ROM) and a flash ROM.

  In addition, when the mobile terminal device in the above embodiment has a configuration that can be connected to a communication network such as the Internet via a communication I / F, the program medium is downloaded from the communication network, etc. Even if it is a medium that carries the program in a fluid way, there is no problem. In this case, it is assumed that a download program for downloading from the communication network is stored in the main device in advance. Or it shall be installed from another recording medium.

  Note that what is recorded on the recording medium is not limited to the program, and data can also be recorded.
