The unit of content is, for example, a page, a spread page, a formal unit (for example, a column) smaller than the page, or a semantic set (for example, a paragraph) independent of the page. The attributes are, for example, a comment, a creation date, a creator, a title, and a file size.

  The main display 107 is a display having a memory display element, such as a cholesteric liquid crystal display or EPD. The main display control unit 108 is a device that outputs a signal for performing drawing control of the main display body 107. Hereinafter, the main display 107 and the main display control unit 108 are collectively referred to as “main display” as necessary. The sub display body 109 is a display body having a display element other than the memory display element, for example, a super twisted nematic liquid crystal display (STN-LCD).

  The ROM 102 stores a control program for performing processing described below. The function shown in FIG. 1 is implemented in the information display device 1 by the CPU 101 executing this control program.

  FIG. 3 is a diagram illustrating an appearance of the information display device 1. In this example, the area of the display surface of the sub display body 109 is smaller than the area of the display surface of the main display body 107 (hereinafter, “display surface of the sub display body 109” is simply referred to as “sub display body 109”). The same applies to the display 107). The main display body 107 has a quadrangular shape, and the sub display body 109 is provided in close contact with the main display body 107 along one side (left side in FIG. 3) which is a part of the periphery of the quadrilateral. Here, “the main display body 107 and the sub display body 109 are in close contact” means that the distance d between the main display body 107 and the sub display body 109 is short enough to maintain visual continuity. . For example, the interval d is a length (for example, 1/2, 1/3, 10%, or 1% or less of the width w) determined based on the width w of the sub display body 109. The length is short or sufficiently short with respect to the width w. Here, the “width” of the sub display body 109 is the length in the direction orthogonal to the portion of the periphery of the main display body 107 that is in close contact with the sub display body 109 (here, the left side of the main display body 107). Say. Alternatively, the interval d is a length (1/2, 1/3, 10%, or 1% or less of the font size) determined based on the character size (font size) of the character string displayed as the main image. However, the length is short or sufficiently short with respect to the font size.

  FIG. 4 is a diagram for explaining the positional relationship between the main display body 107 and the sub display body 109. A main display control unit 108 and a sub display control unit 110 are provided around the main display unit 107 and the sub display unit 109, respectively. The main display body 107 and the sub display body 109 have pixels arranged in a matrix.

Controlled by the supplied signal. The main display control unit 108 includes circuits (Y driver 108Y and X driver 108X) that supply drive signals to the scanning lines and the data lines, respectively. The same applies to the sub display control unit 110. Thus, in this example, the sub display body 109 is disposed along a side parallel to the scanning direction.

  In order to dispose the main display body 107 and the sub display body 109 closely, the main display control unit 108 and the sub display control unit 110 have a side where the main display body 107 and the sub display body 109 are in close contact (see FIG. 4). In the example, it is provided along a side other than the left side of the main display body 107 and the right side of the sub display body 109. In the example of FIG. 4, the Y driver 108 </ b> Y is provided along the right side of the main display body 107, and the Y driver 110 </ b> Y is provided along the left side of the sub display body 109.

2. Operation FIG. 5 is a flowchart showing the operation of the information display apparatus 1. The flow in FIG. 5 is started when a display of a menu screen used for controlling the operation of the information display device 1 is instructed, for example. The information display device 1 stores a list of documents stored therein (hereinafter, this list is referred to as “document information list”, and information included in the document information list is referred to as “document information”).

  FIG. 6 is a diagram illustrating a document information list. The document information list stores information displayed as a main image divided into a plurality of elements. Specifically, the document information list includes, for each of a plurality of documents (elements), at least one attribute among a document ID (Identification), a document name, a file storage location, a display position, a creator, an update date, and the like. Is a list containing In the example of FIG. 6, the document at the top of the list has the document name “Notice of XXX” and the file storage location “a: /folder001/file00.pdf”. At least a part of this list is displayed on the information display device 1.

  A description will be given with reference to FIG. 5 again. In step S101, the CPU 101 sorts the document information list. Here, sorting is performed using, for example, the document name as a key, but the sorting key is not limited to this.

  In step S102, the CPU 101 assigns IDs in order from the top of the sorted list. In the example of FIG. 6, ID = 1 is assigned to the head of the list, and IDs that increase by 1 are assigned to the bottom of the list.

  In step S103, the CPU 101 initializes the display position pos as pos = 1. The display position pos is a parameter that specifies data displayed on the information display device 1 among data included in the document information list.

  In step S104, the CPU 101 determines document information to be displayed on the information display device 1 from the document information included in the document information list. This determination is made, for example, according to an instruction input from the user. The displayed document information is P pieces of document information in a range of n ≦ ID ≦ N (hereinafter referred to as “display range”). Now, a case where n = 35 and N = 44, that is, an instruction to display 10 pieces of document information with ID = 35 to 44 is input will be described as an example (P = 10). The CPU 101 assigns pos = 1, 2,..., 10 to the data of ID = 35, 36,. Further, the CPU 101 initializes the counter i to i = n, i = 35 in this example.

  In step S105, the CPU 101 acquires document information indicated by ID = i from the document information list. In this example, the CPU 101 first acquires document information with a document name “ΔΔ business trip report” with ID = 35.

  In step S106, the CPU 101 calculates the display position of the acquired document information based on the display position pos. This process is performed as follows, for example. An area for displaying document information on the main display is predetermined. The CPU 101 divides the length of this area in the vertical direction (long side direction) into P equal parts. The CPU 101 calculates coordinates indicating the pos-th area from the top of the P-divided area as the display position of the acquired document information. The CPU 101 stores the calculated coordinates in the RAM 103.

In step S107, the CPU 101 controls the main display so as to display the document information indicated by ID = i at the coordinates calculated earlier.
In step S108, the CPU 101 updates the counter i and the display position pos as i = i + 1 and pos = pos + 1.

  In step S109, the CPU 101 determines whether the display of all document information within the display range is completed, that is, whether the counter i satisfies i ≧ (N + 1). When it is determined that i <(N + 1), that is, there is document information that is not displayed (S109: NO), the CPU 101 repeatedly executes the processing of steps S105 to S109. If i ≧ (N + 1), that is, if it is determined that display has been completed for all document information (S109: YES), the CPU 101 proceeds to step S110.

  In step S110, the CPU 101 acquires a display position (hereinafter referred to as “focus position”) of the document information to be displayed in focus. For example, when the document information “☆☆ design document” with ID = 36 in FIG. 6 is displayed in focus, pos = 2 is acquired as the display position of the document information. “Focus display” refers to displaying characters, figures, symbols, etc. (hereinafter referred to as “specific characters”) that specify at least one document information from among a plurality of document information, This refers to figures and symbols. The document information to be displayed in focus is specified by the user's operation input on the UI button group 106.

In step S111, the CPU 101 determines the display position of the focus display on the sub display based on the focus display position.
In step S112, the CPU 101 controls the sub display so as to perform focus display at the determined position.

  In step S113, the CPU 101 determines whether the end condition of the flow is satisfied. The termination condition is, for example, a condition that the determination button is pressed. When it is determined that the end condition is satisfied (S113: YES), the CPU 101 ends the flow of FIG. When it is determined that the termination condition is not satisfied (S113: NO), the CPU 101 repeatedly executes the processes of steps S110 to S112.

  FIG. 7 is a diagram illustrating focus display. In this example, an arrow “→” is displayed as a specific character or the like, and the second document information from the top in the figure is displayed in focus. The position of the specific character or the like changes according to the operation of the UI button group 106 by the user. At this time, the position of the specific character or the like is determined as a position corresponding to any of a plurality of elements, that is, a plurality of document information. Furthermore, since the sub-display is disposed in close proximity to the main display, the line-of-sight movement between the two displays is less than that without the above configuration, and the visual continuity is further improved.

3. Modifications The present embodiment is not limited to the above aspect, and various modifications can be made. Hereinafter, some modifications will be described. In the following, common reference numerals are used for elements common to the embodiments. Two or more of the following modifications may be used in combination.

3-1. Modification 1
FIG. 8 is a diagram illustrating an arrangement of the main display and the sub display according to the first modification. In the above-described embodiment, the length of the sub display and the length of the main display are the same, but the length of the sub display and the length of the main display may be different. Here, the “length” of the display refers to the length of the side where the main display and the sub display are in contact. Here, the “side where the main display and the sub display are in contact” means the side where the distance between the main display and the sub display is the shortest. Further, the position of the end point of the side where the main display and the sub display are in contact with each other may not be the same between the main display and the sub display. Furthermore, the sides where the main display and the sub display are in contact with each other need not be parallel.

3-2. Modification 2
FIG. 9 is a diagram illustrating an arrangement of the main display and the sub display according to the second modification. In the above-described embodiment, the information display device has a single sub-display, but the information display device may have a plurality of sub-displays.

3-3. Modification 3
FIG. 10 is a diagram illustrating an appearance of the information display device 2 according to the third modification. The functional configuration and hardware configuration of the information display device 2 are the same as those shown in FIGS. In the present embodiment, the sub display 109 is a transparent display, that is, a transmissive display that transmits light when no image is displayed. Here, “transparent” means that the light transmittance is a certain threshold value or more. The sub display body 109 has an area smaller than that of the main display body 107 and is arranged so that the entire sub display body 109 overlaps the main display body 107 when viewed from the direction perpendicular to the display surface. The sub display body 109 may have a larger area than the main display body 107.

  FIG. 11 is a diagram for explaining the positional relationship between the main display body 107 and the sub display body 109. The main display control unit 108 and the sub display control unit 110 are arranged at positions that do not overlap each other.

  FIG. 12 is a diagram illustrating a focus display in the third modification. The operation of the information display device 2 is basically the same as that shown in FIG. In this example, the focus display is an oval figure. Since the focus display is displayed so as to be superimposed on the document information, the line-of-sight movement between the two displays is smaller than that without this configuration, and the visual continuity is further improved.

  FIG. 13 is a diagram illustrating another example of the focus display in the third modification. In this example, the headline of a newspaper article is displayed on the main display. One heading is displayed as one document information. In this example, the second heading from the top of the item “Society” is displayed in focus. In this example, a menu is displayed on the sub display in addition to the focus display. The menu is similar to that used in commonly known computer systems. For example, the menu is displayed when the user performs a specific operation on the UI button group 106 after the focus display. The display position of the menu is a position where the relative position with respect to the focus display is a predetermined positional relationship.

  FIG. 14 is a diagram illustrating another example of the positional relationship between the main display body 107 and the sub display body 109 in the third modification. In this example, a part of the sub display body 109 is provided so as to overlap the main display body 107, and the other part of the sub display body 109 does not overlap the main display body 107.

  FIG. 15 is a diagram showing still another example of the positional relationship between the main display body 107 and the sub display body 109 in the third modification. In this example, the sub display body 109 is provided along at least a part of the peripheral edge of the main display body 107 (the left side in this example). In this example, the shape of the sub display body 109, particularly the aspect ratio of the quadrangle, is different from that of the main display body 107. The sub display body 109 overlaps a part of the main display body 107 (the left part in this example).

3-4. Modification 4
The shapes of the main display and the sub display need not be square. Any shape such as a polygon, an ellipse, or a combination thereof may be used.

3-5. Other Modifications The document information list is not limited to that described in the above embodiment. The document information list may include not only information related to documents stored in the information display device 1 but also information related to documents stored in other devices such as a server on a network. Further, the method for determining the display range in the document information list is not limited to the method by the user's instruction input. The information display device 1 may store the previously displayed range, and the stored range may be used as the display range. Alternatively, the display range may be automatically determined by a predetermined algorithm.

  The operation of the information display device 1 is not limited to that shown in the flow of FIG. The document information list sorting process (step S101) may be omitted. Further, in the flow of FIG. 5, when displaying a list of document information, document information is displayed one by one in order, that is, when displaying an image displayed on the main display, elements are displayed one by one in order ( Steps S105-S109). However, all the document information in the display range may be specified first, and then all the document information may be collectively displayed on the main display.

  Image data indicating a main image (hereinafter referred to as “main image data”) may not be stored in a plurality of elements (document information). The main image data may be an image of one page as in the list shown in FIG. In this case, the auxiliary storage device 115 stores data indicating the position of an element (for example, each document information) included in the image. The CPU 101 determines the focus display position based on this data. Alternatively, the main image data itself may include data indicating a position displayed on the main display. In this case, the CPU 101 determines the focus display position based on the main image data.

  The sub display 109 may use a memory display. In short, any display body may be used as long as the rewriting speed is higher than that of the main display body 107.

  A program stored and executed by the information display device is recorded on a recording medium such as a magnetic tape, a magnetic disk, a flexible disk, an optical recording medium, a magneto-optical recording medium, a CD (Compact Disk), a DVD (Digital Versatile Disk), or a flash ROM.
