The number of marks displayed on the scale SC of the lower display bar DB increases as the number of the specific pages increases. However, the size of the scale SC of the lower display bar DB occupying the size of the screen is limited. Therefore, when the number of marks increases, the interval between adjacent marks may be reduced. Details of the mark of this embodiment will be described later.

  The page turning button PB is located at the right end of the display terminal 1 when the display terminal 1 is viewed from the front. The user can turn the page by operating the page turning button PB of the display terminal 1, display the desired page in the page display area PD, and browse the page.

  Menu area MN is located between page display area PD and page turning button PB. The user can make various settings such as mode setting and mark setting (object setting) described later by touching the menu area MN with a touch pen.

  Hereinafter, the configuration of the display terminal 1 of the present embodiment will be described in more detail with reference to FIGS. As illustrated in FIG. 3, the display terminal 1 according to the present embodiment includes a communication unit 10, an operation unit 20, a power supply unit 30, a display unit 40, and a system control unit 50.

  The communication unit 10 is connected to the system control unit 50, and transmits and receives data between the display terminal 1 and the PC 2 wirelessly or in a wired manner in accordance with instructions from the system control unit 50. The data is, for example, data of a document that the user browses using the display terminal 1. The received document data is transmitted to the system control unit 50 and stored.

  The operation unit 20 is connected to the system control unit 50 and receives an operation input from the user for the display terminal 1. The operation unit 20 includes a touch panel and a page turning button PB. The user can operate the touch panel or the page turning button PB to switch the page displayed in the page display area PD to the next page or input various settings of the display terminal 1.

  The power supply unit 30 supplies power to each unit of the display terminal 1. The power supply unit 30 preferably includes a battery as a power supply from the viewpoint of easily carrying the display terminal 1. Moreover, as said battery, it is preferable that they are secondary batteries, such as an alkaline storage battery and a lithium ion battery.

  The display unit 40 functions as a display unit, and displays a page in the page display area PD based on the document data received from the PC 2. In the present embodiment, the display unit 40 includes electronic paper and a display driver (not shown) for driving the electronic paper.

  Hereinafter, with reference to FIG. 4, the structure of the principal part of the electronic paper with which the display part 40 is provided is demonstrated in detail. The electronic paper of the display unit 40 includes a support layer 41, a back electrode 42, an adhesive layer 43, a transparent electrode 44, a surface layer 45, and a microcapsule 46. The microcapsule 46 has a black pigment 46a and a white pigment 46b.

  The electronic paper employs an electrophoretic display technique using a microcapsule 46 in which a black pigment 46a having a negative charge and a white pigment 46b having a positive charge are encapsulated together with a transparent dispersion medium such as oil.

  The surface layer 45 is a front substrate made of a transparent material such as a PET (Polyethylene Terephthalate) film, and a transparent electrode 44 made of a transparent conductive film such as ITO (Indium Tin Oxide) is disposed on the back side thereof. . The support layer 41 is a back substrate made of an insulating material such as a polyimide film, and a back electrode (segment electrode) 42 made of a minute metal plate corresponding to each microcapsule 46 is arranged on the front side. Has been.

  The above-described microcapsules 46 are arranged between the individual back electrodes 42 and the transparent electrodes 44, and the individual microcapsules 46 are joined to the individual back electrodes 42 through the adhesive layer 43. In this way, a large number of microcapsules 46 arranged two-dimensionally in the space between the front substrate (surface layer 45) and the back substrate (support layer 41) via the two electrode plates 42 and 44 have the above-mentioned electrons. A paper display area is formed.

  The display principle of the microcapsules 46 arranged in this way is as follows. When a positive potential is applied to the back electrode 42 corresponding to one microcapsule 46, the negatively charged black pigment 46a moves to the back surface electricity 42 side, and the positively charged white pigment 46b moves to the transparent electrode 44 side. Since it moves, the microcapsule 46 displays white when viewed from the front side of the display area.

  Similarly, when a negative potential is applied to the back electrode 42 corresponding to one microcapsule 46, the positively charged white pigment 46b moves to the back electrode 42 side, and the negatively charged black pigment 46a becomes a transparent electrode. Therefore, the microcapsule 46 displays black when viewed from the front side of the display area.

  As shown in FIG. 5, the system control unit 50 functions as a control unit, and includes an HDD (Hard Disk Drive) 51, a RAM (Random Access Memory) 52, a ROM (Read Only Memory) 53, and a CPU (Central Processing Unit). ) 54, and these components are connected to each other by an internal bus 55.

  The HDD 51 stores various software such as a display program DP and an OS (Operating System) (not shown). The HDD 51 stores the data of the document created by the PC 2 and received by the communication unit 10.

  The RAM 52 temporarily stores the various software, the document data, the calculation result when the CPU 54 executes the display program DP, and the like.

  The ROM 53 stores various parameters used when the CPU 54 executes the display program DP.

  The CPU 54 implements the display method of the present embodiment by executing the display program DP. Hereinafter, the display method of the present embodiment will be described in more detail with reference to FIGS. FIG. 6 is a flowchart for explaining the display method of the present embodiment, and FIG. 7 is a schematic diagram for explaining the lower display bar of the display terminal shown in FIG. 8A to 8D are schematic diagrams for explaining a case where a specific page is searched on the display terminal of the present embodiment.

<Overview of display method>
In the following, an outline of the display method of this embodiment will be described by exemplifying a case where a specific page including a handwritten graphic (character) as shown in FIG. 2 is searched from a document. The document includes a plurality of pages containing handwritten graphics (characters), and the pages containing each handwritten graphic (characters) are marked at corresponding positions on the scale SC of the lower display bar DB. Is attached. In the present embodiment, it is assumed that the user displays pages one by one based on these marks, confirms the contents, and searches for a target page. In the present embodiment, the page corresponds to the content, the mark corresponds to the object, and the scale SC of the lower display bar DB corresponds to the object display area.

  As shown in FIG. 6, first, display of a page is started (step S101). The CPU 54 controls the display unit 40 to display the first page of the document stored in the HDD 51 in the page display area PD.

  Next, it is determined whether or not the mark has been operated (step S102). In this embodiment, it is determined whether or not a mark as an object has been touched with a touch pen. As shown in FIG. 7, the user touches the mark M attached on the scale SC of the lower display bar DB with the touch pen 60. In the present embodiment, a case where a mark M is attached corresponding to a page including a handwritten figure (character) of the document will be described as an example. However, the page with the mark M is not limited to a page including a handwritten graphic (character), and may be a page including “bookmark”, for example. Further, the page to which the mark M is attached may be a list of search results obtained under certain conditions for searching for a desired page or file. Further, the pages to which the mark M is attached may be all the pages included in the document when the document includes a small number of pages.

  The CPU 54 determines whether or not the mark has been operated. When the mark is operated (step S102: YES), that is, when the mark M is touched with the touch pen 60, a page corresponding to the operated mark M is displayed (step S103). The CPU 54 instructs the display unit 40 to display a page corresponding to the mark M touched with the touch pen 60.

  Next, it is determined whether or not a predetermined condition is satisfied (step S104). The predetermined condition is a condition related to a display execution status. If the predetermined condition is not satisfied (step S104: NO), the process is terminated. As the predetermined condition, for example, the number of page display times reaches a predetermined number. Although the predetermined number of times can be set to an arbitrary value, in the present embodiment, the predetermined number of times is set to 1. The predetermined condition can be set in addition to the number of times the page is displayed reaching the predetermined number. Details of other predetermined conditions will be described later.

  On the other hand, when the predetermined condition is satisfied (step S104: YES), the mark display form is not displayed (step S105). In the present embodiment, the CPU 54 instructs the display unit 40 not to display the mark associated with the page. That is, the mark is hidden. As described above, in the present embodiment, when the mark M is touched with the touch pen 60, the number of display times of the page reaches one of the predetermined number of times and satisfies the predetermined condition. Therefore, the mark associated with the displayed page The display form of is changed (hidden).

  After the processes in steps S101 to S105 are executed, the user determines whether the displayed page is the target page, and ends the page search if the displayed page is the target page that was being searched for. To do. On the other hand, if the displayed page is not the target page that the user is looking for, the CPU 54 is caused to execute the processes of steps S102 to S105 described above again. Hereinafter, with reference to FIG. 8A to FIG. 8D, the case where the user searches for a specific page including a handwritten figure (character) of a document is illustrated, and the operation of the display terminal 1 of the present embodiment is more specifically illustrated. I will explain it.

  As shown in FIG. 8A, the document has seven pages containing handwritten figures (characters), and marks M1 to M7 are attached to the scale SC of the lower display bar DB corresponding to each page. Has been. At this stage, the user must select one of the seven marks M1 to M7. First, for example, the user touches the mark M4 with the touch pen 60 to display and browse a page corresponding to the mark M4.

  Next, as shown in FIG. 8B, since the mark M4 is touched with the touch pen 60, the mark M4 is not displayed. However, since the page is not the target page that the user was looking for, the user must restart the page search. In this case, since the mark M4 is not displayed, the user may select from the marks M1 to M3 and the marks M5 to M7 excluding the mark M4. In the example shown in FIG. 8B, the user touches the mark M7 to display and browse a page corresponding to the mark M7.

  Next, as shown in FIG. 8C, since the mark M7 is touched with the touch pen 60, the mark M7 is not displayed. However, since the page is not the target page that the user was looking for, the user must restart the page search. In this case, since the mark M4 and the mark M7 are not displayed, the user may select from the marks M1 to M3, the mark M5, and the mark M6 excluding the mark M4 and the mark M7. In the example illustrated in FIG. 8C, the user touches the mark M6 to display and browse a page corresponding to the mark M6.

  Next, as shown in FIG. 8D, since the mark M6 is touched with the touch pen 60, the mark M6 is not displayed. However, since the page is not the target page that the user was looking for, the user must restart the page search. This time, since the mark M4, the mark M6, and the mark M7 are not displayed, the user may select from the marks M1 to M3 and the mark M5 except the mark M4, the mark M6, and the mark M7. In the example shown in FIG. 8D, the user touches the mark M5 to display and browse a page corresponding to the mark M5. Since the page is a target page that the user has been searching for, the user ends the page search process.

  Thus, in this embodiment, in the process in which the user searches for a specific page including a handwritten figure (character), the touch pen 60 is touched among the marks attached to the scale SC of the lower display bar DB. The mark is hidden.

<Predetermined conditions>
In the above description, the case where the number of page display times reaches the predetermined number (one time) has been described as an example as the predetermined condition regarding the display execution state. However, in the present embodiment, the conditions can be added or changed so as to impose other predetermined conditions without being limited to the predetermined conditions described above. For example, the setting of the condition regarding the predetermined number of times may be configured such that the user can specify any number of times.

  Further, the predetermined condition may be set from a viewpoint different from the above display count. For example, a “search mode” may be further provided in order to change a display form of a mark associated with a page displayed during a specific period. That is, as a predetermined condition, the system control unit 50 is configured to change the display form of the mark associated with the displayed page only during the period in which the mode setting is “search mode”. In the present embodiment, the user can switch to the “search mode” by touching “search mode” in the menu area MN, for example.

  Further, as the predetermined condition, the display form of the mark may be changed according to the operation form for the mark. For example, when the mark is touched with the touch pen 60, the system control unit 50 may be configured so that the display mode of the mark can be changed according to one click, double click, and long press.

  In addition, if there is a problem if the mark display form is changed without notifying the user, the user may obtain approval before changing the mark display form. Specifically, when the display of the displayed page is finished, it is a predetermined condition that the user accepts an operation to change the display form of the mark associated with the page. . And when the said predetermined condition is satisfied, you may comprise so that the display form of the said mark may be changed. For example, when the display of the displayed page is ended, a message is displayed on the screen for confirming to the user whether the display form of the mark after the end may be changed because the page is displayed. On the other hand, the system control unit 50 is configured to change the display form of the mark when the user performs an operation to approve.

  In addition, when the number of marks displayed on the scale SC of the lower display bar DB is small, it is easy for the user to identify each mark, so there is no need to change the display form of the displayed marks. Therefore, when the number of marks is less than a predetermined number, the display form of the displayed marks may not be changed. In the present embodiment, there is a mark setting in which information about the mark is set, and the mark setting includes a predetermined threshold value regarding the number of marks displayed on the scale SC of the lower display bar DB. Then, assuming that the number of marks is equal to or greater than the predetermined threshold value, and when the predetermined condition is satisfied, the display form of the mark is changed. On the other hand, when the number of marks displayed on the scale SC of the lower display bar DB is less than the predetermined threshold, the display form of the marks is not changed.

  Further, the system control unit 50 may be configured to make the display size of the mark variable. When the display size of the mark is large, the predetermined threshold is decreased, and when the display size is small, the predetermined threshold is increased. That is, in the limited area of the scale SC of the lower display bar DB, if the display size of the mark is large, the possibility that the marks approach or overlap each other increases, so the predetermined threshold is set small. On the contrary, when the display size of the mark is small, the possibility that the marks approach or overlap each other is low, so the predetermined threshold is set small. Further, the center value of the predetermined threshold may be arbitrarily set by the user.

<Returning the mark display format>
You may comprise so that the mark once changed in the display form can be returned to the original display form by predetermined | prescribed operation. For example, when the “display reset key” is provided in the menu area MN and the “display reset key” is touched with the touch pen 60, the system control unit 50 is set so that the mark whose display form has been changed returns to the original display form. It may be configured.

  In addition, when the “search mode” is ended, the system control unit 50 may be configured so that the mark whose display form has been changed during the period returns to the original display form.

  Further, the system control unit 50 may be configured such that the mark whose display form has been changed returns to the original display form after a first predetermined time since the display form has been changed.

  Moreover, the system control unit 50 may be configured such that the mark whose display form has been changed returns to the original display form when there is no operation on the display terminal 1 for the second predetermined time or more.

  In addition, the system control unit 50 may be configured such that the mark whose display form has been changed returns to the original display form when the pages included in the HDD 51 are reduced to a predetermined number or less.

<Change display / redo>
The system control unit 50 stores a history of changes in the mark display form, and can cancel or redo the change in the mark display form based on the history. Specifically, a history of changes in the mark display form is stored, and changes in the mark display form are canceled or redone using the “Undo” / “Redo” function. You may comprise the system control part 50 so that it can do.

  Further, the system control unit 50 may be configured so that the display form can be restored to the original state by applying a predetermined operation to the position of the mark whose display form has been changed.

<Change of mark display format>
In the present embodiment, the user can easily identify the mark associated with the displayed page and other marks by switching the display / non-display of the mark. In addition to switching the display / non-display of the mark, the size, color, transmittance, and action of the mark (shake, shake, become larger or smaller, become thinner or darker) , And so on) can be changed.

<Type of mark>
In the present embodiment, the mark can be associated with a page including a handwritten graphic (character), a bookmark, a comment, a tag, an edit, or a search result.

<Exclusion rules>
If the display time of the page is shorter than the third predetermined time, the mark display form may not be changed.

  In the display terminal, display method, and display program of the present embodiment described above, the mark M is displayed on the scale SC of the lower display bar DB of the screen, and is displayed when a predetermined condition regarding the display execution state is satisfied. The display form of the mark M associated with the page is changed.

  The display terminal, the display method, and the display program of the present embodiment described above have the following effects.

  According to the display terminal, the display method, and the display program of the present embodiment, the display form of the mark M associated with the displayed page is changed, so that the mark M displayed on the scale SC of the lower display bar DB is changed. It can suppress that identification becomes difficult. As a result, even when there are many pages including handwriting, it is possible to easily find a desired page in the scale SC of the lower display bar DB without narrowing the page display area for displaying the page. .

(Second Embodiment)
In the first embodiment, the display terminal and the display method of the present invention are exemplified by a configuration in which a specific page including a handwritten graphic (character) is searched from a document based on a mark associated with the page. The display program has been described. In the second embodiment, the display terminal, the display method, and the display program of the present invention will be described by exemplifying a configuration for searching for a specific file stored in the display terminal based on the icon displayed in the icon display area.

  As shown in FIG. 9, the display terminal 1 'of the present embodiment is a tablet terminal provided with a page display area PD, an icon display area ID, a menu area MN, and a page turning button PB.

  In the icon display area ID, an icon IC associated with a file stored in the HDD 51 or the RAM 52 of the system control unit 50 is displayed. The number of icons displayed in the icon display area ID increases as the number of files increases. However, the size of the icon display area ID occupying the size of the screen is limited. Therefore, when the number of icons increases, the interval between adjacent icons may be reduced. The icon display area ID is located below the page display area PD when the display terminal 1 ′ is viewed from the front. The arrangement of the icon display area ID is not limited to the lower side of the page display area PD.

  In the present embodiment, the file corresponds to content, the icon IC corresponds to an object, and the icon display area ID corresponds to an object display area. The CPU 54 implements the display method of the present embodiment by executing a display program DP ′ (not shown). Hereinafter, the display method of this embodiment will be described in more detail with reference to FIG.

  As shown in FIG. 10, it is first determined whether or not an icon has been operated (step S201). The CPU 54 determines whether an icon as an object is touched with a touch pen. When the icon is operated (step S201: YES), that is, when the icon IC is touched with the touch pen 60, a file corresponding to the operated icon IC is displayed (step S202). The CPU 54 instructs the display unit 40 to display a file corresponding to the icon IC touched with the touch pen 60.

  Next, it is determined whether or not a predetermined condition is satisfied (step S203). The predetermined condition is a condition related to a display execution status. If the predetermined condition is not satisfied (step S203: NO), the process is terminated. As the predetermined condition, for example, the number of times the file is displayed reaches a predetermined number. Although the predetermined number of times can be set to an arbitrary value, in the present embodiment, the predetermined number of times is set to 1. The predetermined condition can be set in addition to the number of times the file is displayed reaching the predetermined number. The details of the other predetermined conditions are the same as the predetermined conditions described in the first embodiment, and a description thereof will be omitted.

  On the other hand, if the predetermined condition is satisfied (step S203: YES), the icon display form is hidden (step S204). In the present embodiment, the CPU 54 instructs the display unit 40 not to display the icon associated with the file. That is, the icon is hidden. As described above, in the present embodiment, when the icon IC is touched with the touch pen 60, the number of times the page is displayed reaches one of the predetermined number of times and satisfies the predetermined condition, so the icon associated with the displayed file is displayed. The display form of is changed (hidden).

  After the processes in steps S201 to S204 are executed, the user determines whether the displayed file is a target file, and ends the file search if the displayed file is the target file that was being searched for. To do. On the other hand, if the displayed file is not the target file being searched for, the CPU 54 is caused to execute the above-described steps S202 to S204 again.

  Hereinafter, with reference to FIG. 11A to FIG. 11D, the operation of the display terminal according to the present embodiment is specifically illustrated by selecting an icon displayed in the icon display area and searching for a specific target file. I will explain it. In this embodiment, the user selects and searches each icon displayed in the icon display area with the touch pen until a specific target file is found.

  As shown in FIG. 11A, in this embodiment, for example, ten files are stored in the HDD 51 or the RAM 52 of the system control unit 50, and the icons IC1 to IC10 correspond to the respective files in the icon display area IC. It is displayed. At this stage, the user must select one of the ten icons IC1 to IC10. First, for example, the user touches the icon IC9 with the touch pen 60, opens a file corresponding to the icon IC9, and confirms the contents.

  Next, as shown in FIG. 11B, since the icon IC9 is touched with the touch pen 60, the icon IC9 is not displayed. However, since the file is not the target file that the user was looking for, the user must restart the file search. This time, since the icon IC9 is not displayed, the user may select from the icons IC1 to IC8 and the icon IC10 excluding the icon IC9. In the example shown in FIG. 11B, the user touches the icon IC6 to open a file corresponding to the icon IC6 and confirm the contents.

  Next, as shown in FIG. 11C, the icon IC6 is touched with the touch pen 60, so that the icon IC6 is not displayed. However, since the file is not the target file that the user was looking for, the user must restart the file search. This time, since the icon IC6 and the icon IC9 are not displayed, the user may select from the icons IC1 to IC5, the icon IC7, the icon IC8, and the icon IC10 excluding the icon IC6 and the icon IC9. In the example shown in FIG. 11C, the user touches the icon IC3 to open a file corresponding to the icon IC3 and confirm the contents.

  Next, as shown in FIG. 11D, since the icon IC3 is touched with the touch pen 60, the icon IC3 is not displayed. However, since the file is not the target file that the user was looking for, the user must restart the file search. This time, since the icon IC3, icon IC6, and icon IC9 are not displayed, the user does not include the icon IC3, icon IC6, and icon IC9, but the icon IC1, icon IC2, icon IC4, icon IC5, icon IC7, icon IC8, icon IC10 You can choose from In the example shown in FIG. 11D, the user touches the icon IC2 to open a file corresponding to the icon IC2, and confirms the contents. Since the file is the target file that the user has been searching for, the file search process ends.

  As described above, in the present embodiment, the user is touched with the touch pen 60 among the icons displayed in the icon display area ID in the process of searching for a specific file stored in the HDD 51 or the RAM 52 of the system control unit 50. The icon is hidden.
