That is, it can be seen that the amount of written or recorded on the 5th day (1502) rather than on the second day (1501) is large. When a date is selected, information on the amount of handwriting and recording may be displayed. Also, if you select the displayed handwriting and recording, you will switch to that page.

16 is a block diagram of an apparatus for generating a handwriting of an electronic pen.

16, an electronic pen-based computer (hereinafter referred to as an 'apparatus') 1600 is connected to an electronic pen (not shown) and includes a receiving unit 1610, a control unit 1620 and a display unit 1630.

The receiving unit 1610 receives information according to the code from the electronic pen, and stores the application.

When the application is first run, the control unit 1620 starts a procedure for registering the electronic pen. The device 1600 and the electronic pen can be connected by Bluetooth, and when they are connected for the first time, the device 1600 goes to the pairing mode. If the pairing mode is already set, the electronic pen is turned on. If the application is running, the procedure for registering the electronic pen does not proceed, and the control unit 1620 automatically connects the electronic pen. When the electronic pen is shipped from the factory or goes to the pairing mode for the first time after resetting, the user can set a password through the application. Then, if another device is in the pairing mode, a password must be entered before pairing can be set. In addition, if the Bluetooth function is disabled in the device, the application may activate this function according to the user's selection. Although the connecting means is described as Bluetooth in the present invention, there is no limitation on the wireless or wired connection means of the device and the electronic pen.

Except for the procedure for registering the electronic pen, when the application is started, the note menu is started. At least one note being used by the user is registered and displayed in the application. The note menu includes an identifier for the note, a title of the note, a date of creation, an indicator for indicating the number of notes, and an item for indicating note information. The identifier for the note may be an image or a thumbnail of the note, an identifier for a plurality of notes may be displayed, or an identifier for one note may be displayed, and an identifier for another note may be displayed by dragging or the like. In addition, the note menu may further include an item capable of Bluetooth connection with the electronic pen and / or an item indicating an entire menu for the application. Items that can be connected to the electronic pen with Bluetooth can provide a function to connect the electronic pen and the device 1600 by selecting it when the electronic pen and the device 1600 are not connected.

When selecting an image or thumbnail of the currently displayed note in the note menu with a submenu of the note menu, a page menu is provided. The page menu includes an identifier for the note, the latest usage time information of the current page, and at least one page image or thumbnail.

The page view menu will be described in more detail below with reference to the writing of the electronic pen.

The receiving unit 1610 receives from the electronic pen a code printed on a predetermined code, for example, the code information recognized by the electronic pen according to the writing of the electronic pen on the page. The code information includes information on a note and page information.

The control unit 1620 generates a trajectory of handwriting based on the received code information.

The control unit 1620 creates a separate window on the display unit 1630. Based on the received code information, the control unit 1620 acquires the information of the printed matter (for example, a note) and the page information in the printed matter. Thereafter, when the printed matter or the page displayed on the display unit 1630 does not correspond to the acquired information of the printed matter or the page information of the printed matter, the control unit 1620 creates a separate window. For example, if the printed matter information currently displayed on the display unit 1630 is 'N-note No. 1' and the page information is '04page', the printed matter information obtained from the code information is 'N-note No. 2' The controller 1620 generates a separate window if the size of the window does not correspond to the size of the display unit 1630. The size of the window is not limited as long as it is smaller than the size of the display unit 1630, There is no limitation.

The display unit 1630 displays the generated trajectory of the handwriting in a separate window. The range of the trajectory displayed in the window can be in a certain range in the stroke unit.

In another embodiment, it may be converted to a page view menu without creating a separate window.

Also, when the displayed page is selected, it is switched to the selected page view mode. The setting menu includes a pen information item which is information on the electronic pen specification, an app information item which is information on the application specification, an e-mail setting item for sending the page image, a text conversion language pack item, an application item to be interlocked and the like. An announcement menu for receiving and displaying information from the server to which the application is connected, and a firmware update menu for electronic pen firmware update. In the explanation of the apparatus, the description of the application example in Figs. 1A to 15 is the same and is omitted.

The method of displaying the handwriting of the electronic pen as described above can also be implemented as a computer-readable code on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording media in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like. The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes, and code segments for implementing the disk management method can be easily deduced by the programmers of the present invention.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
