The e-book document input slot 12 includes a detachable mechanism for attaching and detaching a memory pack containing the e-book document. The e-book document file stored in the memory pack is included in the I / O controller 16. Is an interface device to transmit

Here, the memory pack is a removable and replaceable storage medium containing an e-book document, for example, a read-only ROM pack ("ROM" pack) or OTP pack (One Time Programmable Pack) or e-book It can be a Flash Memory Pack that can rewrite a document multiple times.

The memo storing slot 13 is for storing memo contents and index data in a writable memory pack, and includes a detachable mechanism for detaching the writable memory pack. Here, the writable memory pack may be a flash memory pack.

The key input unit 14 generates a corresponding key signal when the operation button 3 and the power on / off button 4 are operated, and inputs them to the processor 17 through the I / O controller 16. The touch screen input unit 15 converts a pen input through the touch screen 5 into an electrical signal and inputs the I / O controller 16 to the processor 17 via the I / O controller 16.

The I / O controller (Input / Output Controller) 16 controls data input / output with a peripheral device, a USB port 10, a USB controller 11, an e-book document input slot 12, and a memo storing slot. (13) and a signal input from the key input unit 14 and the touch screen input unit 15 are input to the processor 17, and data on the memo contents output from the processor 17 is stored for the memo slot 13 ).

The processor 17 controls an operation of each component of the e-book terminal, operates an operating system and a viewer program, and controls for interpreting and displaying e-book documents and memo contents. It is a control computing device that performs the operation.

The ROM 18 is a memory device that stores an operating system and a viewer program, and is a read-only device. For example, the ROM 18 may be a mask ROM.

The random access memory (RAM) 19 is a storage device for a temporary storage space in which an operating system, a viewer program for displaying an e-book document, and other simple programs are executed. For example, the RAM 19 is dynamic. RAM (Dynamic Random Access Memory; " DRAM ").

The flash memory 20 is a memory device that stores data structure and tag information of an e-book document, and has a nonvolatile memory characteristic in which data is preserved even after the power is turned off. It is a memory device capable of random access.

The display controller 21 drives the display element 21 under the control of the processor 17 to display the contents of the e-book document or the memo contents.

Now, a method of recording a memo in an e-book document using the e-book device configured as described above will be described.

First, when the user turns on the power on / off switch 4 in the e-book terminal, power is applied to each component of the e-book terminal from a predetermined power supply means (for example, a battery). The initial state becomes possible, and the operating system and the viewer program are loaded from the ROM 18 into the RAM 19 under the control of the initialized processor 17.

By the operating system and the viewer program loaded into the RAM 19, the processor 17 stores a memo index file (EMI) containing index information on memo contents from a memory pack inserted into the memo storing slot 13. (S20), the index information contained in the memo index file (EMI) is stored in the index table of the RAM 19 or the flash memory 20.

Next, the processor 17 reads an ebook content file (EBC) from the memory pack inserted into the ebook document input slot 12 by the viewer program (S30), and controls the display controller 21. The electronic book document of the page selected by the user through the operation button 3 or the electronic pen 6 is displayed through the display element 2 (S40).

At this time, the processor 17 searches the index table stored in the RAM 19 or the flash memory 20 to see if there is a memo recorded in the page on which the current e-book document is being displayed (S50), and the search result is displayed on the current page. If no memo is recorded, the process proceeds to step S80 to be described later.

On the other hand, if a memo is recorded on the page on which the current e-book document is displayed in step S50, the processor 17 stores a memo content file (EMemo Content; "EMC) from the memory pack inserted into the memo storage slot 13; After reading "), the memo content is read from the memo content file EMC according to the index information of the index table stored in the RAM 19 or the flash memory 20 (S60), and displayed through the display controller 21. The element 2 is displayed (S70).

Next, the processor 17 checks whether the user inputs a memo (S80), and when the user inputs the memo, the user writes the memo by simply touching the electronic pen 6 to the touch screen 5 without any manipulation. In addition, due to the characteristics of the touch screen 5, an input signal is transmitted even when the human body, such as a finger, is touched in addition to the electronic pen 6, so that a memo is input among a plurality of operation buttons 3 to prevent such a misunderstanding. You can also record a memo after operating the dragon button.

Accordingly, the processor 17 may check whether the user inputs a memo by a signal input from the touch screen input unit 15 or the key input unit 14.

If the user does not enter a memo in step S80, the processor 17 returns to the step S40 of displaying the e-book document of the page selected by the user, while the user enters the memo on the touch screen. The display controller 21 determines the contents of the memo input by the user through a signal input from the input unit 15, that is, the bitmap on the display screen and displays the memo input by the user according to the determined bitmap. To control.

Next, the processor 17 checks whether a signal for switching a page of the e-book document is input from the key input unit 14 or the touch screen input unit 15 (S100), and the user switches the page of the e-book document as a result of the check. If so, the contents of the memo displayed on the display device 2 to date are stored in the memo content file EMC (S110).

Here, the processor 17 compresses the bitmap for the portion where the memo is written on the display screen, and stores the data for the compressed bitmap for each page in the memo content file EMC. Since storing the bitmap is inefficient, including bitmap data up to the non-memory part, as shown in FIG. 5, the display screen is divided into predetermined number and size segments (S1 to S8) in advance. Compresses and stores only the bitmap of the recorded segment.

Next, the processor 17 modifies the contents of the memo index file EMI according to the contents of the memo stored in the step S110 (S120), and once the contents of the index table of the RAM 18 or the flash memory 20 are changed. After the modification, the contents of the memo index file EMI stored in the memory pack inserted into the memo storage slot 13 are modified according to the information of the index table of the RAM 18 or the flash memory 20 at a predetermined time. . The predetermined time point may be when switching pages of the e-book document or when the e-book terminal is powered off.

For example, the memo index file EMI may be configured as follows.

『EMI:

CMPR,

PN, SN, START_OFFSET, END_OFFSET,

PN, SN, START_OFFSET, END_OFFSET,

........ 』

In the configuration of the memo index file EMI, “CMPR” is a compression method, “PN” is a page number where a memo is recorded, and “SN” is a memo of a plurality of segments divided on a display screen. Segment number recorded, "START_OFFSET" indicates the start position of memo data of the page number and segment number in the memo content file (EMC), and "END_OFFSET" indicates the memo content file (EMC) This indicates the end position at which the memo data of the page number and the segment number are stored. If the value of "START_OFFSET" or "END_OFFSET" is "0", it indicates that there is no memo in the segment of the page.

Next, the processor 17 checks the page of the displayed e-book document and checks whether the e-book document is read (S130).

If the e-book document is not read as a result of the check in step S130, the processor 17 returns to step S40 to display the e-book document of the page selected by the user, while the e-book document is displayed. When it is read, the display and recording of the e-book document and the memo are finished.

As described above, in one embodiment of the present invention, in addition to the memory pack slot containing the e-book document, the memory pack slot for storing the memo additionally installed and through this to store the contents of the memo in the memory pack that can be read and written By doing so, the memo contents can be stored. In this case, even when the storage capacity is exceeded due to a large amount of memo contents, the storage capacity can be expanded by simply replacing the memory pack.

In addition, there are various types of memos such as dots, lines, faces, and continuous dotted lines, making it difficult to store each memo individually, and the storage capacity becomes too large when all the data on the entire display screen is stored. In the present invention, by dividing the display screen into a predetermined number of segments and managing whether or not the memo is input by each segment unit, the bitmap of the segment part into which the memo is input can be stored efficiently, so that various types of memos can be efficiently stored with a minimum capacity. have.

In addition, the stored memo should be displayed quickly every time the page is changed in the e-book document. If the memo content increases, the search and display of the memo cannot be performed quickly. Accordingly, in the present invention, a memo index file is provided separately from a memo content file containing memo contents, and the memo index file includes location information in which data about memo contents is recorded for each page and segment in the memo contents file. The search for the presence or absence of the memo contents and the reading of the memo contents were performed quickly.

Meanwhile, in the above-described embodiment of the present invention, a case in which the memo and memo index information are stored in a separate memo storage memory has been described as an example. According to another embodiment of the present invention, the memo and memo index information are separately included. In addition to the memory for storing the memo can be stored in a read-write memory device (for example, flash memory) built in the e-book terminal, according to another embodiment of the present invention, the e-book document is read and write When stored in a possible medium (eg, a flash memory pack), the memo and memo index information may be stored in an extra storage space of the medium in which the e-book document is stored.

As described above, the present invention provides a touch screen for inputting a memo using an electronic pen or the like on top of the display element, and the contents of the memo input through the touch screen are different from a memory pack for an e-book document. It is to be stored in a separate memo storage memory pack, it is possible to freely record a memo in an e-book document through an e-book terminal like a conventional book. In addition, in addition to a separate memo memory pack, a memo may be recorded in a memory embedded in an e-book terminal or a memory containing an e-book document.

In the present invention, when storing the contents of the memo, by dividing the display screen into a predetermined number of segments, and managing the input of the memo for each segment, only the bitmap data of the segment into which the memo is input, thereby saving the bitmap of the entire display screen. Compared to the case of storing all the data, the storage capacity can be used efficiently by minimizing the storage capacity.

In addition, the present invention, by storing the information about the location of the data stored in the memo content file in a separate memo index file, whether the memo is recorded on the page when switching pages of the e-book document It is possible to quickly detect the presence and minimize the time for reading and displaying memo contents.
