  However, with the configuration of the conventional example as described above, for example, a conventional book in which a red line or an underline is drawn at an important place or a character is emphasized with a marker pen cannot be naturally achieved. In this respect, usability is significantly different from actual paper books.

  The present invention has been made in view of such conventional problems, and an object of the present invention is to realize an electronic book apparatus capable of drawing a line in a sentence or writing an emphasis or a memo like a conventional book. And

  The invention according to claim 1 of the present invention displays the book data held in the storage medium, displays the writing data for the book data as needed, and reads and writes the book data held in the storage medium. A storage medium control unit that records write data in the storage medium when requested, and a key signal provided on the electronic book apparatus main body, and the user can select any content in the book data displayed on the display unit. To the display unit, an image memory that temporarily holds frame data to be given to the display unit, a write content storage unit that stores data written by the input unit, and a write portion When there is a display request from the input unit, the write data and the storage medium stored in the write content storage unit The held book data is converted into frame data, and the display control unit provided to the display unit and the processing content instructed from the input unit are discriminated, and the book data in the storage medium according to the processing content And an overall control unit that reads out the write data in the write content storage unit and generates a control signal for giving to the display control unit.

  As a result, various writings such as patterns and illustrations can be performed in the text. Each time a page is opened, the contents written to each page are read from the written contents storage unit and displayed. This makes it easy to see where important points are written.

  According to a second aspect of the present invention, in the electronic book device of the first aspect, the written data is stored in the written content storage unit as a file associated with the book data.

  According to a third aspect of the present invention, in the electronic book device of the first aspect, the write data is stored in the storage medium as a file associated with the book data.

  According to the second and third aspects of the invention, even when the book data is moved to another electronic book apparatus, the file storing the written contents is associated. Therefore, if the file is moved together, the same written content can be displayed even when the book data is displayed on another electronic book apparatus.

  According to a fourth aspect of the present invention, in the electronic book device of the first aspect, the written content storage unit stores the position information indicating the writing location for the book data and processing content information indicating the type of written content. It is characterized by doing.

  Thus, regardless of which page is to be displayed, the presence / absence of the contents written to the corresponding page and the contents thereof can be immediately searched by searching the position information. For this reason, the time required to display the written contents can be minimized.

  According to a fifth aspect of the present invention, in the electronic book device according to the first aspect, the written content storage unit stores processing order information indicating an order in which the written data is recorded.

It is memorized in a format.

  As a result, in the case of processing on text, only the type of processing and its range need be stored, so the capacity of the storage unit for storing the written contents can be greatly reduced.

  According to a ninth aspect of the present invention, in the electronic book device of the first aspect, the overall control unit prioritizes the book data when displaying the written content with respect to the text data, and displays the written content with respect to the non-text data. Issues a command to display written data in preference to the book data.

  As a result, it is possible to formulate an optimal format for writing text data that requires less capacity. For this reason, the storage capacity for storing the total written contents can be reduced.

  According to a tenth aspect of the present invention, in the electronic book device according to the first aspect, the overall control unit has priority to determine which of the book data and the written data is to be displayed on the display unit based on the written content. It has a degree discriminating means.

  As a result, when writing to text such as underline and marking is performed, the book data is displayed without disappearing. In addition, when writing is performed on a non-text portion as in the case of illustration insertion, there is no inconvenience that a part of the illustration is covered with book data.

  The invention according to claim 11 is the electronic book device according to claim 1, wherein the overall control unit indicates which of the book data and the writing data is displayed with priority when the display unit displays the writing content. A priority flag is issued.

  This increases the degree of freedom in deciding whether book data such as originally displayed characters will be partially hidden by writing or whether part of the written content will be partially hidden by book data. Can do.

  According to a twelfth aspect of the present invention, in the electronic book device according to the first aspect, the display unit has two display surfaces that are displayed in two spread pages, and the operation is performed when one of the display surfaces is operated. It is characterized in that a small screen showing the operation content is output on the display screen on the side that is not displayed.

And illustrations can be inserted, and the effect of being very easy to read is obtained.

  Hereinafter, an electronic book device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of an electronic book device according to an embodiment of the present invention. The overall control unit 1 is composed of a CPU and operates based on an instruction code written in the program memory 4. The overall control unit 1 controls the key input unit 2, the pen input unit 3, the memory 5, the display control unit 6, and the storage medium control unit 9, reads the book data stored in the storage medium 10, and displays it on the display unit 7. Issue the command to As a unique functional block of the overall control unit 1 in the present embodiment, an invalidating unit 1a, a discriminating unit 1b, and a priority determining unit 1c are provided.

  The invalidating means 1a is a means for temporarily invalidating the data so that the contents written by the user are not displayed on the display unit 7. The discriminating means 1b is a means for discriminating whether the content of writing is for text data or non-text data when the book data is divided into text data and non-text data. The priority discriminating means 1c is a means for discriminating which of the book data and the written data is to be displayed on the display unit 7 on the basis of the written contents.

  The key input unit 2 is various keys provided on the electronic book apparatus main body. The overall control unit 1 discriminates these key signals, and when the user specifies a desired range using the pen input unit 3 in the book data displayed on the display unit 7, its position information and drawing data (non-text) Data). When the user writes arbitrary contents to the book data displayed on the display unit 7 using the pen input unit 3, the overall control unit 1 determines these drawing data.

  Since the memory 5 stores the write data written by the pen input unit 3, it is called a write content storage unit. When there is a display request for the writing portion by the key input unit 2 or the pen input unit 3, the display control unit 6 frames the writing data stored in the memory 5 and the book data held in the storage medium 10. Data is converted and given to the display unit 7. The display unit 7 displays the book data held in the storage medium 10 and displays write data for the book data as needed. The display unit 7 also has a touch panel function, and generates a position signal of a point pressed by the pen input unit 3. Here, the key input unit 2 and the pen input unit 3 receive a signal of a key provided in the electronic book apparatus main body, and input the user writes arbitrary contents in the display unit 7 in the book data displayed on the display unit 7. Has achieved the function of the department.

  The storage medium 10 stores book data in a file format, and may be a non-volatile semiconductor memory card that is detachable from the electronic book apparatus main body, and is an optical disk such as a CD-ROM or DVD-RAM. May be. The storage medium controller 9 reads the book data held in the storage medium 10 and records the write data in the storage medium 10 when there is a write request.

  FIG. 2 is an external view centering on a display unit of the electronic book apparatus. This electronic book apparatus has a right screen 7R and a left screen 7L as the display unit 7. A page feed key 15, a bookmark key 17, a write key 19, and a menu key 21 are provided as a key input unit 2 on a part of the right panel of the electronic book apparatus main body 12. Further, a page feed key 16, a bookmark key 18, a write key 20, and a write hide key 22 are provided on a part of the left panel of the electronic book apparatus main body 12.

  Next, operation of the electronic book apparatus illustrated in FIG. 1 will be described with reference to FIG. When a menu button 21, which is one of the key input units 2, is pressed, the content is transmitted to the overall control unit 1, and then a list of book data stored in the storage medium 10 is displayed on the display unit 7. . When the user selects which book to read, the book data is displayed on the display unit 7. Actually, the display control unit 6 converts the content to be displayed on the display unit 7 into frame data and writes it into the image memory 8. The display control unit 6 reads out the book data (referred to as image data at this stage) from the image memory 8 according to an instruction from the overall control unit 1 and displays the image data on the display unit 7. As described above, the display unit 7 includes two screens, the right screen 7R and the left screen 7L. When the page feed keys 16 and 15 are pressed, the next page or the previous page is displayed. Here, since the screen is composed of two screens, for example, when the page feed key 16 is pressed, the page two pages ahead is displayed. This is exactly the same as turning a sheet of paper in a normal book. Such processing is the same as the conventional electronic book apparatus.

  This electronic book apparatus also has a bookmark function. When the bookmark key 17 shown in FIG. 2 is pressed, the screen 7R is processed as having a bookmark. When the bookmark key 18 is pressed, the screen 7L is processed as having a bookmark. This process is also the same as the conventional electronic book apparatus.

  If the writing content corresponding to the book data is in the writing data file, the overall control unit 1 reads the writing data file from the memory 5 and gives it to the image memory 8 via the display control unit 6. As a method of associating with the book data, a method of changing the file extension or creating a directory with the same name except the file name extension indicating the book data, and storing necessary files in the directory There is a technique such as.

  FIG. 3 is a flowchart showing the write processing sequence. FIG. 4 is a display example showing the contents of the write menu when a write instruction is given. When the write key 19 in FIG. 2 is pressed, the write request in step S41 becomes “Yes” in the sequence shown in FIG. 3, and the process proceeds to step S42. In step S42, the request content for writing is confirmed. In this case, the menu 51 shown in FIG. 4A is displayed on the screen 7R. Here, since the screens 7R and 7L are touch panels, a command is selected by pressing one of the areas on the screen using the pen 23 as shown in FIG. When a specific area is pressed by the pen 23, which area of the screen is pressed by the pen input unit 3 in FIG. 1 is transmitted to the overall control unit 1. The overall control unit 1 detects which item is selected based on the area, that is, position information. Here, there are menus of "Underline", "Marking", "Strikethrough", "Sticker Paper", "Illustration", "Write Hide", "Show All", "Trace", "Cancel Write" as selection items. It is prepared. Among these, “underline”, “marking”, and “strikethrough” are processes for text.

  The case where “underline” corresponding to text processing is selected will be described in detail using the processing sequence shown in FIG. If "underline" is selected, the pattern or color designation request is accepted in step S81. Here, a new menu 52 shown in FIG. 4B is displayed. Here, the line type and color used for the underline are selected using the pen 23 shown in FIG. When the selection is completed, the area displayed as “next” in FIG. 4B is pressed.

  If “marking” is selected, a menu 61 as shown in FIG. 6A is displayed. In this case, the marking type and marking color for the character are designated. When “strikethrough” is selected, a menu 71 as shown in FIG. 6B is displayed. In this case, the type of strikethrough to be written is selected. These displays are performed as the process of step S81 in FIG. In any case, when the selection is completed, the area displayed as “next” is pressed, and the next screen is displayed.

  When the area displayed as “next” is pressed, Y (Yes) is selected in step S82, and the process proceeds to step S83. In this step S83, a processing range designation request is displayed on the opposite page. That is, as shown in FIG. 7, the guide 92 is displayed as a small screen on the right side in the screen 7 </ b> L, that is, on the whole electronic book apparatus, near the center. The guide 92 is a guide indicating that a range to be underlined is designated. In this way, by displaying the guide on the opposite side of the page where the range is specified, it is possible to always display what is being sought, and the display is not obstructed regardless of which part is specified. . Then, using the pen 23, the user designates by tracing the underlined range. Here, the portion of the reverse display 91 is designated as an underlined range. In general, the operation contents performed by the key input unit 2 or the pen input unit 3 are commands, procedures, and guides.

  When the range specification is completed, “OK” is pressed in the guide 92 shown in FIG. As a result, “OK” is selected in step S43 of FIG. 3, and the process proceeds to the next step S44. Here, processing based on the content of the write instruction is performed. In this example, a line is displayed on the right side of the character of the reverse display 91 that is the designated range. In this embodiment, since the book data is displayed vertically, the underline is interpreted as a right line.

  Next, the process proceeds to step S45 in FIG. 3, and the write contents are written into the write data file. Here, the written contents are recorded in a format as shown in FIG. That is, the attribute (ATTRB; attribute), location information, and processing content information are recorded separately. 9 to 11 are format diagrams showing write contents. The attributes correspond to b (bits) 12 to b15 of word 1 in FIG. 9, and the location information corresponds to b0 to b11 of word 1 and b0 to b11 of word 2. Further, the processing content information corresponds to b12 to b15 of word 2, b0 to b15 of word 3, and b0 to b15 of word 4.

  The attribute includes a flag indicating whether the writing is for text or writing when the screen is captured as an image, and a flag indicating whether the writing is valid / invalid. These flags are identified by the discriminating means 1b in FIG. If the invalidation means 1a designates invalidity with this flag, the display regarding this item is not performed. When “write hide” which is the invalidating means 1a is selected in the menu 51 of FIG. 4A, this flag indicates “invalid”. Here, the format is changed depending on whether the written content is for text.

  First, if the written content is for text, it is recorded in a file in the format shown in FIG. Words b14 to b15 are bits for text. B1 to b13 of word 1 are flags indicating the validity / invalidity of writing. Words b0 to 11 of the word 1 are page information indicating which page is written. B2 to b11 of the word 2 are start position information, and indicate from what character of the corresponding page the processing is performed. As information of the processing contents 1 to 3 illustrated in FIG. 9, information representing types 1 to 3 in FIG. 10, a processing range, and a processing order are stored. B15 of word 3 is a priority flag indicating a priority (P; priority), and indicates which of book data and written data is to be displayed with priority. This priority order is discriminated by the priority discriminating means 1c in FIG. The type 1 of b12 to 15 of the word 2 indicates the type of processing such as “underline”, “marking”, and “strikethrough”. The type 2 of b4 to b7 of the word 2 indicates a line type or a pattern type. Type 3 of b3 to b0 of word 2 is information for representing color designation in “underline” and “marking”.

  Words b0 to b7 are data indicating the processing range, and here, it is determined how many characters from the start position the processing is performed. Words b8 to b15 are information indicating the processing order, and indicate what number the writing has been performed on the page. As a result, for example, writing performed on the page can be reproduced sequentially from the beginning.

  By recording the written content to the text in the above format, the necessary written content can be recorded while suppressing the amount of information. Even if the number of characters per line changes, underline processing, marking processing, and the like can be reliably performed on the same character.

  In the above embodiment, the page information and the start position information indicating the number of characters are used as the location information. However, if the page separation is ambiguous, Paragraph information may be used for Alternatively, if the paragraph is ambiguous, the number of characters indicating the number of characters counted from the first character of the document may be used. In order to allow these to be mixed, it is more effective to newly provide information for identifying what the position information indicates.

  Next, a case where the written content is not for text (hereinafter referred to as non-text), for example, “illustration” or “sticky paper” will be described. In this case, the file is recorded in the format shown in FIG. Words b14 to b15 are non-text bits. The other bits in word 1, b15 priority flag in word 3, and b8 to b15 in word 4 are the same as those in FIG.

  In FIG. 11, b0 to b11 of word 2 and b0 to b11 of word 3 indicate start position information. Here, the position on the screen is recorded in units of pixels. The start position information 1 indicates the horizontal axis direction, and the start position information 2 indicates the vertical axis direction. Information indicating the type of writing is stored in b12 to b15 of word 2. Here, whether it is “sticky paper” or “illustration” is written. Words b0 to b7 are information indicating file names. This is a file of contents to be displayed on the display unit 7 as “sticky paper” or “illustration”. Here, for example, if the file name of the book data is “shoseki.ebk”, if it is “sticky paper”, then shoseki001. dat, if it is “illustration”, shoseki001. As gif, the three-digit part before the extension is converted into binary data and recorded.

  The “sticky note paper” is a function for displaying a character string surrounded by a frame, for example, at a desired place on the screen. This is the same effect as sticking a sticky note on a normal book. “Illustration” is a function of placing a free line or pattern with a pen 23 or the like as shown in FIG. Here, the content of the “sticky note” function is stored in a text file, and the content of the “illustration” function is stored in a bitmap file or a compressed file thereof.

  The contents to be displayed as “sticky note” or image data written by the pen 23 as “illustration” is stored in the file designated here. The locations for displaying the contents of these files are indicated by the start position information 1 assigned to b0 to b11 of word 2 and the start position information 2 assigned to b0 to 11 of word 3 shown in FIG. Has been. In this way, by setting the non-text content as a separate file, it can be stored in the write data file 31 without worrying about the number of writes and the size of each write.

  Here, the priority flag will be described. The priority flag indicates which of the book data and the written data is displayed with priority as described above. This flag is not always necessary. If this flag is not present, the book data is prioritized for writing to the text. In this way, as shown in FIG. 13 (A), when marking the book data, the book data is on the top and displayed in the same manner as if it was marked with a marker pen in a normal book. can do. On the other hand, as shown in FIG. 13B, the character under the marking cannot be read.

  Conversely, when writing other than text, such as illustration writing, writing is prioritized over book data. That is, FIG. 12 is written by the illustration function, but the illustration is clearly displayed even if the book data is somewhat hidden in this way. These are based on conventional paper books.

  However, there are cases where it is better to draw a line on the character, for example, “strikethrough”. In this case, it is possible to uniquely set which priority order is set for each item in advance, and process according to that. However, there are cases where it is desired to hide specific characters as shown in FIG. This hides certain characters when an important word is written in the place and the word must be remembered. In this case, if a priority flag is provided, writing priority can be set. For example, if marking is performed with writing priority, characters at a desired location can be hidden. In such a case, a priority flag may be provided, and display priority may be given according to the contents.

  Next, other items in the menu 51 of FIG. 4 will be described. “Writing and hiding” is a function of not displaying specific contents of temporarily written contents. “Display all” is a function to restore those that are hidden by “write hide”. “Trace” is a function for displaying the writings made on the page again from the beginning in the order of writing. “Write cancel” is a function for erasing written contents. The difference from “write hide” is that “display all” does not return.

  In the above embodiment, the write data file 31 is recorded in the memory 5 in FIG. 1, but may be recorded in the storage medium 10. In the case of storing in the memory 5, it is desirable that the memory 5 is a non-volatile memory or a battery-backed one. In short, even if the power source of the electronic book apparatus main body 12 is turned off, it is sufficient that the data is not lost.

  In the above embodiment, “underline”, “marking”, and “strikethrough” are given as the processing for text. Processing such as “shading” is also possible. The processing content is not limited as long as it can be performed in units of characters.

  In the present embodiment, the write keys 19 and 20 are provided. However, when the menu key 21 is pressed, an option corresponding to the write key may be displayed in the menu. Further, in the above embodiment, the display unit 7 is used as a touch panel, and various inputs are performed with a pen. However, it may be a normal non-touch panel that performs various types of writing by moving the cursor and executing buttons on the menu screen. Moreover, in said embodiment, although step S44 was performed after implementing step S44 in FIG. 3, which may be performed first.

  10 and 11, the processing order indicated by b8 to b15 of the word 4 is the order within the page in the present embodiment, but may be the order of the book data as a whole. Further, although the amount of information is increased, data indicating the date and time when the writing was performed may be used. In addition, the format of the write data file is the format shown in FIGS. 10 and 11. However, the format is not limited to this, and any other format may be used as long as the written contents can be reproduced correctly.

  Moreover, although the case where the electronic book apparatus main body 12 has two screens is described in this embodiment, the electronic book device main body 12 may have only one screen. In this case, for example, the range-designating guide 92 shown in FIG. 7 disappears several seconds after display, and “OK” and “Cancel” are displayed as key buttons. For example, as shown in Patent Document 1, the same effect can be obtained by using buttons such as “ENTER” and “CANCEL”. Furthermore, in the present embodiment, the case where the sentence is written vertically is shown, but the same effect can be obtained even if the sentence is written horizontally.

  Since the electronic book device of the present invention has a writing function, it is possible to write lines, markings, and the like on an arbitrary page of a conventional book or electronic notebook.
