Description

Portable eletronic-book and Operating method

The present invention relates to a portable e-book, and more particularly, a portable electronic book reader capable of underlining a desired point, reading a circle or triangle, or making a short memo while reading. It's about books.

In general, a portable e-book is a device that allows a user to read a file that can be used in a computer without printing a printer, and includes a flat panel display such as a liquid crystal display and an operation switch. 1 and 2 are perspective views schematically showing a conventional portable e-book.

The portable e-book may be classified into two types, such as a memory built-in type shown in FIG. 1 and a memory replaceable type shown in FIG. 2, according to a structure.

The memory-embedded e-book has a memory device (not shown) for storing an e-book file therein, and the e-book file stored in the memory device through a separate communication means on the flat panel display device 10. Display and provide the content of the book to the user. The memory built-in e-book preferably includes a transmission means 40 such as a parallel port or a serial port. The reason for this is that the e-book cannot provide various kinds of documents to the user unless the transmission means 40 capable of communicating with the outside is included in the memory-ready e-book.

The memory replaceable e-book does not have a built-in memory element, and a separate memory pack (not shown) in which the contents of the book are stored can be inserted into an interface device 50 such as a slot. It is configured to be. Such a memory pack stores one or more computer files and can be easily separated from an e-book. Therefore, the memory replaceable e-book can provide many kinds of documents to the user by swapping the memory pack.

Each e-book is provided with several operation switches 30 including page up / down keys so that a user can easily read the contents of the book. In addition to the page-up and page-down switches that display the contents of a book one screen on a flat-panel display, these control switches adjust font size. ), A power switch that controls the on / off of the power supply.

In general, as shown in FIGS. 1 and 2, the operation switch 30 of the e-book is located in front of the case 20 in which the flat panel display device 10 is formed. And, most of these operation switches are composed of a TACT switch device.

The tact switch is configured to connect two terminals by a push operation or a corresponding operation, and is controlled by generating a predetermined pulse in a single click operation or a continuous on state. Generate a signal.

The conventional memory-embedded portable e-book operates as follows. 3 is a flowchart illustrating the operation of the conventional memory-embedded portable e-book.

When the user presses the power switch of the portable e-book to turn on the e-book, the contents of the document stored in the memory are provided to the user through the flat panel display. At this time, if the user reads some of the contents of the document and bookmarks a predetermined position before turning on the e-book (S10), the portable e-book prefers the contents of the bookmarked portion. Provided to (S14).

When the user presses a page up switch (S12), the flat display device of the portable e-book displays one page or a predetermined amount of content from the position of the currently displayed content (S15). ). Alternatively, when the user presses a page down switch (S12), the flat display device of the portable e-book displays one page or a predetermined amount of content from the position of the currently displayed content (S13). .

In addition, when a user attempts to turn off the e-book by pressing the power switch of the portable e-book, the portable e-book stores and bookmarks the location of the document currently displayed on the flat panel display, that is, the address of the memory. Shut off the supply. At this time, the operation of blocking the supply of power and the bookmark operation may be made in conjunction with each other, the bookmark operation may be made separately from the power off.

For example, a portable e-book equipped with an independent bookmark switch can bookmark the contents of a document by pressing the bookmark switch when the user needs it. Therefore, the user of the portable e-book including the independent bookmark switch can separately perform the bookmark operation regardless of the power supply.

Meanwhile, the conventional memory replaceable portable e-book operates as follows. 4 is a flowchart illustrating the operation of a conventional memory replaceable portable e-book.

When the user presses the power switch of the portable e-book to turn on the e-book, the memory replaceable portable e-book detects whether the memory pack and the interface slot (interface slot) where the contents of the document are fastened (S20). If the memory pack and the interface slot are not coupled to each other, the memory replaceable portable e-book cannot display the contents of the document stored in the memory pack on the flat panel display.

When the memory pack and the interface slot are fastened to each other, the memory replaceable portable e-book displays the contents of the document stored in the memory pack on the flat panel display (S22). At this time, if the user reads some of the contents of the document stored in the memory pack and bookmarks a predetermined position before turning on the e-book (S21), the memory replaceable portable e-book is bookmarked. The content of the part is preferentially provided to the user (S23).

In addition, since the operation when the user presses the page up switch and the page down switch is almost the same as the portable electronic book with a built-in memory, detailed description thereof will be omitted.

In addition, when a user attempts to turn off the e-book by pressing the power switch of the portable e-book, the portable e-book stores the position of the document currently displayed on the flat panel display, that is, the address of the memory, in the memory pack fastened to the interface slot. Bookmark and cut off the power supply. At this time, the operation of blocking the supply of power and the bookmark operation may be made in conjunction with each other, the bookmark operation may be made separately from the power off.

For example, a portable e-book equipped with an independent bookmark switch can store a desired location of a document in a memory pack by pressing the bookmark switch when the user needs it. Therefore, the user of the portable e-book including the independent bookmark switch can separately perform the bookmark operation regardless of the power supply.

As described above, a user using a conventional portable electronic book reads the contents of a document stored in a memory. Therefore, if the contents of the novel book are stored in the memory, the user of the e-book with the memory can read the novel. If the contents of the reference book are stored in the memory, the user of the e-book with the memory can read the reference book. will be.

On the other hand, there are some differences depending on the reading habits of each individual, but usually, underlined or circled in the part that touches the mind or is considered important during reading. In some cases, a brief note of the thoughts that occurred as you read the passage.

In this way, when you open the book even after a long time since you have read it, it is common to see the emotions of those days as if you underlined it or marked it with a circle. .

However, in the case of the conventional portable e-book, there was a problem in that it was not possible to provide an underline function, a marker function such as a circle, or a memo function, which were possible in a book made of a general paper as described above.

The present invention has been made to solve this problem, to provide a portable e-book that can be underlined, a circle or triangular marker, or a short memo while reading by using a portable e-book There is this.

In the portable e-book according to the present invention, the memory unit 100 shown in FIG. 5 may be separated and may be embedded in the portable e-book main body 200. However, in the embodiment of the present invention, when the memory unit is separated, Explain.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

5 is a block diagram of a portable e-book according to the present invention. Referring to FIG. 5, the portable e-book according to the present invention includes a book data memory area 110 for storing book data in a conventional memory, and a bookmark memory area 120 for storing an address for the specific book data as bookmark information. And a reading data memory area 130 for storing memo notes of the viewers who read the book data as separate reading data, a mapping memory area 140 for mapping the book data and the reading data, and book data. The first fastening means 150 connected to the memory area 110, the bookmark memory area 120, the browsing data memory area 130, and the mapping memory area 140 and having a structure capable of data communication when combined with a corresponding fastening means. Memory unit (100) having a; When combined with the first fastening means 150, the second fastening means 210 having a structure capable of data communication, and the processed book data processed by mapping the reading data generated when reading the book data and the book data. A mapping unit 220 for outputting, a flat panel display unit 230 capable of displaying the book data or the processed book data in a predetermined display area (Display Area, Active Area) by n bytes, and the flat plate When the viewer reading the book data through the type display unit 230 makes a memo by touching the flat panel display unit 230, the flat panel display unit 230 detects the reader's touch and converts the memo into an electrical signal. A touch panel device 230 disposed above, a first key 251 for inputting a bookmark designation signal, a page up signal or a page down signal; 2 keys 252 and the first body When the means 150 and the second fastening means 210 are coupled to each other, the book data currently displayed on the flat panel display 230 by converting the electric signal input through the touch panel unit 240 into reading data of the viewer. The specific book data or the processed book by storing in the browsing data memory area 130 together with an address value of the key, or by referring to an output signal of the key input units 251 and 252 or a bookmark reference information address of the bookmark memory area 120. And a control means (or processor) 260 for displaying data on the flat panel display unit 230 and executing a corresponding control operation according to input of a bookmark designation signal, page up signal or page down signal by a user. It consists of a main body 200.

Here, when a bookmark designation signal is input, the control means 260 uses any one of the information currently displayed on the flat panel display 230 as bookmark reference information, and uses the memory address of the book data memory area 110 in which the bookmark reference information is stored. The memory is stored as a memory value in the bookmark memory area 120. In addition, when the page down signal is input, the control means 260 uses any information corresponding to the screen currently displayed on the flat panel display 230 as the first page reference information, and the book data memory in which the first page reference information is stored. After adding m bytes to the memory address of the region 110, information from the memory address added by m bytes to the memory address n bytes later is displayed on the flat panel display 230, while control is performed when the page up signal is input. The means 260 makes any information corresponding to the screen currently displayed in the display area as the second page reference information, subtracts m bytes from the memory address of the book data memory area 110 in which the second page reference information is stored, The information from the memory address subtracted by the m bytes to the memory address after the n bytes is displayed on the flat panel display unit 230.

At this time, n should be greater than or equal to m, but more preferably greater. If the user applies the page up signal or the page down signal to read the next or previous screen, at least one line of information read on the immediately preceding or subsequent screen must be duplicated so that the user can read the contents smoothly. Because.

The first page reference information and the second page reference information may be displayed at the same position on the flat panel display 230. For example, if the information displayed in the first row of the first column in the flat panel display 230 is designated as the first page reference information, the second page reference information is also designated as the information displayed in the first row of the first column. .

Hereinafter, a detailed configuration and simple operation of each component of the portable viewing device according to the present invention shown in FIG. 5 will be described.

First, the bookmark memory area 120, the browsing data memory area 130, and the mapping memory area 140 shown in FIG. 5 may include static-random access memory (S-RAM), flash memory, and EEP-ROM ( Electronic Erased Program (Read Only Memory), such as a non-volatile memory that can be arbitrarily erased by using an electric signal. On the other hand, the book data memory area 110, as well as S-RAM, flash memory, EEP-ROM, It consists of memory that cannot be arbitrarily erased by using electric signals such as EP-ROM, P-ROM, or Mask-ROM.

The book data memory area 110, the bookmark memory area 120, the browse data memory area 130, and the mapping memory area 140 may be configured as one memory element. The memory element at this time is preferably composed of a nonvolatile memory except for a memory that cannot be arbitrarily erased by using an electrical signal such as an EP-ROM, a P-ROM, or a Mask-ROM. Because the bookmark memory area 120, the browsing data memory area 130, and the mapping memory area 140 are deleted or stored from time to time, they may be arbitrarily erased by using an electrical signal such as an EP-ROM or a mask-ROM. This is because it is inconvenient to use a memory device that cannot be used. Accordingly, in order for the book data memory area 110, the bookmark memory area 120, the browsing data memory area 130, and the mapping memory area 140 to be integrated into one memory device, the memory device may include an S-RAM, a flash memory, It is preferably selected from memory elements that can be arbitrarily erased by using an electrical signal such as an EEP-ROM.

Currently, general-purpose flash memory has a data retention period of about 10 years without power being supplied. Therefore, since there will be few users who insert the bookmark for 10 years, the flash memory may be a memory device that is very suitable to be used as the bookmark memory region 120, the browsing data memory region 130, and the mapping memory region 140. . Of course, if the memory manufacturing technology is more advanced than the present level, and the retention period of the flash memory is much longer than the present, the book data memory area 110, the bookmark memory area 120, the browsing data memory area 130, and the mapping memory Region 140 will naturally be integrated into one flash memory.

In addition, the first fastening means 150 of the memory unit 100 shown in FIG. 5 and the second fastening means 210 of the main body 200 may include a data transmission cable, an interface bus, and a transmission bus. A fastening device such as an interface slot or the like. Therefore, when the first fastening means 150 and the second fastening means 210 are fastened to each other and connected to enable data communication, the book data of the book data memory area 110 and the address stored in the bookmark memory area 120 are connected. And the browsing data of the browsing data memory area 130 and the processed book data of the mapping data memory area 140 are transmitted from the memory unit 100 to the control means 260, and also the bookmark signal, page up signal or page down. The signal is transmitted from the control means 260 to the memory unit 100. In addition, a flash memory transfer slot or a PCMCIA slot may be used as the first fastening means 150 and the second fastening means 210. In particular, using the flash memory transfer slot has the advantage that you can use a commercially available flash memory unit immediately.

Further, the first key 251 for generating the bookmark signal shown in Fig. 5 is a two terminal switch element. Therefore, when the two-terminal switch element is changed from the off state to the on state, the book data memory area is set such that any one of the information corresponding to the screen currently displayed on the flat panel display unit 230 is set as the bookmark reference information. The corresponding memory address of 110 is stored in the bookmark memory area 120.

In addition, the first key 251 may selectively turn on and turn off the power as necessary. For example, when a bookmark signal is generated by the user pressing the first key 251, the control means 260 may determine the memory address of the book data memory area 110 in which the bookmark reference information is stored. 120) and then power off. On the other hand, when the user presses the first key 251 while the power is off, the power supply is resumed to determine whether the first fastening means 150 and the second fastening means 210 are coupled.

In addition, the second key 252 generating the page up signal or the page down signal shown in FIG. 5 is used by one three-phase switch element that can have three states of page up, page down, and off. do. Therefore, the page-up signal is generated when the three-phase switching element is in the page-up state, the page-down signal is generated when the page-down state is in the off state, and no signal is generated when it is in the off state.

In addition, the second key 252 may be configured by using only the first switch generating the page up signal and the second switch generating the page down signal. At this time, like the first key 251, the first switch and the second switch use a two-terminal switch element. Accordingly, the information displayed on the flat panel display 230 is scrolled up or down by the page up signal and the page down signal.

In some cases, the second key 252 may be manufactured to reverse the roles of the page up signal and the page down signal. For example, the second key 252 may page down information currently displayed on the flat panel display 230 by a page up signal, and may be paged down on the current flat panel display 230 by a page down signal. The displayed information may be paged up.

In addition, the control means 260 included in the main body 200 shown in FIG. 5 drives the ROM 262 and the ROM 262 in which the control program is stored, and controls the overall operation of the portable viewing device. It consists of a microprocessor 261. Here, the ROM 262 and the microprocessor 261 may be configured in the form of a one chip microcomputer integrated into one. In addition, the control program stored in the ROM 261 may provide various types of flowcharts. In addition, it will be apparent that the mapping unit 220 may be integrated into the microprocessor 261.

In addition, the flat panel display 230 (Flat Panel Display) illustrated in FIG. 5 is selected from display elements such as a liquid crystal display (LCD), a plasma display panel (PDP), and the like. In particular, the flat panel display unit 230 applied to the portable e-book according to the present invention uses a liquid crystal display unit having a size that is easy to carry and consumes less power than a computer.

For reference, the Roman letters are one-byte (8-bit) characters each having a capacity of one byte per memory element. On the other hand, two-byte (16-bit) characters such as Korean, Japanese, and Chinese have a capacity of two bytes per memory element. Therefore, 20 or more horizontal characters based on 1-byte characters such as Roman characters mean 10 or more horizontal characters based on 2-byte characters.

In addition, since the flat display unit 230 is not easy to carry when the size is too large, it is preferable to have a size of approximately 210 mm or less and 297 mm or less. This is because the size of a general book has a size of A4 size (210 mm x 297 mm) or less.

6 is a control flowchart illustrating an operation operation procedure of the portable e-book according to the present invention. 6 illustrates an example in which the memory units are not embedded in the portable e-book of the present invention as shown in FIG. 5 and are coupled to each other through fastening means.

First, when the user provides power to the portable e-book, the control means 260 determines whether the main body 200 and the memory unit 100 are coupled (S31). At this time, if the main body 200 and the memory unit 100 are not coupled to each other, the control means 260 outputs a guide message of "combining the memory unit" to the flat panel display 230 (S32). . On the other hand, when the main body 200 and the memory unit 100 are coupled to each other, the control means 260 reads the stored address value from the bookmark memory area 120 storing the address of the book data as bookmark information (S33). ).

Subsequently, the control means 260 reads the book data of the page to which the current memory address belongs from the book data memory area 110 using the read address value as the current memory address (S34).

Here, the page means that the book data stored in the book data memory area 110 is grouped by a predetermined amount in order to manage the book data by the control means 260, and the predetermined amount is referred to as one page. It is like a page found in a paper book. Accordingly, each book data is grouped and managed for each page, and correspondingly, the address of each book data is also grouped for each page of the book data.

That is, the address read from the control means 260 as the current memory address is an address of a memory that stores certain book data. This address will also have a page to which it belongs. In step S34, all the book data constituting the page to which the address belongs is read.

Subsequently, the control unit 260 stores the memo notes of the viewers who read the book data as separate reading data, together with the address of the page of the book data, of the page to which the current memory address belongs. If there is browse data associated with the address of the page, the search data is retrieved if the browse data stored in association with the address is present (S35).

Subsequently, the mapping unit 220 controls the control means 260 to map the book data read from the book data memory area 110 and the read data read from the read data memory area 130 into a mapping memory. The mapping operation is performed using the area 140 (S36).

The data in which the browsing data is processed in the book data is referred to as processed book data. For this processed book data, the control means 260 processes the processing data corresponding to the current memory address among the processed book data in the processed mapping memory area 140. Information stored at positions from the book data to the memory address n bytes later is displayed on the flat panel display 230 (S37). Thus, the user can see the first screen of the information file that he wants to read.

Subsequently, when the user inputs a specific control signal, the control means 260 controls a desired operation according to the type of the control signal (bookmark, page up signal, page down signal, etc.). For example, the control unit 260 determines whether the input signal is a bookmark signal (S38), and when the bookmark signal is input, the control unit 260 may refer to the arbitrary information corresponding to the screen currently displayed on the flat panel display unit 230. In step S39, the memory address of the book data memory area 110 in which the reference information is stored is stored as an address value in the bookmark memory area 120 (S39). At this time, among the arbitrary information, the memory address of the book data, which is the beginning of the page, may be used based on the page set when the control means 260 manages the book data. The memory address of the book data may be changed, and various other methods may be used.

Subsequently, when the input signal is not the bookmark signal, the control unit 260 determines whether the signal is a page-up signal (S40) and when the page-up signal is input, the control unit 260 corresponds to the screen currently displayed on the flat panel display 230. Arbitrary information is used as reference information, and the information from the memory address of m bytes before to the memory address of n bytes after the memory address of the book data memory area 110 in which the reference information is stored is displayed on the flat panel display unit 230. (S41). On the other hand, when the page-up signal is not input as a result of step S40, the control means 260 determines that the page-down signal is input to the arbitrary information corresponding to the screen currently displayed on the flat panel display unit 230, the reference information In the memory address of the book data memory area 110 in which the reference information is stored, information from the memory address after m bytes to the memory address after n bytes is displayed on the flat panel display unit 230 (S42).

In the present invention described above, it is described that the user applies the power after coupling the memory unit to the main body of the portable viewing device. However, when the user couples the memory unit to the main body of the portable viewing device, the control means 260 may automatically control the power to be supplied to the portable viewing device. In such a case, it may be unnecessary to determine whether the main body 200 and the memory unit 100 are coupled to each other (S31).

In addition, even when the memory unit is built in the main body, the step of determining whether the main body 200 and the memory unit 100 shown in FIG. 6 will be unnecessary.

However, once the memory unit 100 and the main body 200 are combined, the address value stored in the bookmark memory area 120 of the memory unit 100 is read.

At this time, if the address value read by the control means 260 is zero or zero, the information stored in the flat memory display unit 230 stores information stored from the first memory address of the mapping data memory area 140 to a memory address n bytes later. That is, if there is no stored bookmark information, such as when the user first uses the product, the first page information of the mapping data memory area 140 is displayed. On the other hand, if the control means 260 can read a specific address value, the flat display unit 230 stores information stored in a position from a memory address of the mapping data memory area 140 indicated by the address value to a memory address n bytes later. Display information on.

Of course, according to the setting of the control means 260, except for the reading data generated by the viewer of the book data, if only the original book data is desired to be viewed, the book data memory can be directly accessed without access to the mapping data memory area 140. The book data may be read from the area 110 and displayed on the flat panel display 230.

In such a case, when the address value read out by the control means 260 is zero or zero, the information stored in the flat panel display unit 230 stores information stored from the first memory address of the book data memory area 110 to a memory address n bytes later. do. In other words, if there is no stored bookmark information, such as when the user first uses the product, the first page information of the book data memory area 110 is displayed. On the other hand, if the control means 260 can read a specific address value, the flat panel display unit 230 stores information stored in a position from a memory address of the book data memory area 110 indicated by the address value to a memory address n bytes later. Information can be displayed at.

Next, when the viewer views the book data of the book data memory area 110 or the processed book data of the mapping memory area 140 through the flat panel display unit 230 and takes a memo through the touch panel unit 240. Let's look at the operation.

7 is a flowchart illustrating a method of operating a portable e-book according to the present invention, and describes a process of storing the memo of the viewer through the touch panel unit. Referring to FIG. 7, first, when the portable e-book according to the present invention is powered on, the current memory address is read in the book data memory area by reading the stored address from the bookmark memory area and using the read address as the current memory address. The process of reading and mapping the reading data stored together with the address of the page to which the current memory address belongs in the book data and the reading data memory area of the page to which the page belongs, is displayed on the flat panel display as described above. In the following description, only the memo generated by the viewer by the touch panel unit 240 is converted into reading data of an image and stored in the reading data memory area 130.

When the book data or the processed book data is displayed on the flat panel display unit 230, the reader reads (reads) the displayed book data and places an underline, a circle, a triangle, or the like where it is considered important. You can write notes.

That is, when a reader reading a book data touches a flat panel display to take a memo, the touch panel 240 is installed on the flat panel display to sense a touch of the viewer and converts the touch into an electrical signal. (S51).

The electrical signal converted through the touch panel unit 240 is input to the control means 260 is converted into image data for storage as an image file (S52). At this time, the control means manages the image data for each page of the book data as in the case of managing the book data.

That is, the touch signals of the viewers converted into electrical signals through the touch panel unit 240 are stored in the reading data memory area 140 as one image file as a group for each page of the book data. When the touch signal input through the touch panel unit 240 is stored as an image file, a storage form or a storage method of the image file may be various, such as JPG, TIF, ..., and thus the detailed description thereof will be omitted. .

The image file is stored as one image file for each page of the book data. The storage interval is possible at any time operated by the viewer by the operation of the key input units 251 and 252, and the storage interval is set for a predetermined time. Set to so that it is automatically saved every time.

In addition, when the control means 260 stores the image file for each page of the book data as the browsing data in the browsing data memory area 130, the control unit 260 does not simply store the image file, but instead stores the image file in the generated one image file and the image file. The page address of the associated book data or the address of the book data belonging to the page is stored together in the browse data memory area 130 (S53).

By doing so, when the portable e-book according to the present invention is turned on as described above, the address of the book data memory area 110 corresponding to the read address is first read from the address stored as the bookmark information in the bookmark memory area 120. After reading the data and reading the image file which is the browsing data of the browsing data memory area 130 corresponding to the read address and processing it in the mapping memory area 140, the flat display unit 230 by the stored amount of the control means 260. Will be displayed.

The portable e-book according to the present invention described above provides the following effects.

In the conventional portable e-books, only the contents of the required pages are read or the pages that have been read are marked by the bookmark function, but in the present invention, the underlined, circled or triangular, etc. By marking or short notes, the user's reading efficiency can be very excellent.
