       FIG. 1  is a block diagram illustrating a mobile terminal according to an embodiment of the present disclosure. 
     Referring to  FIG. 1 , a mobile terminal  100  may include a controller  110 , a storing unit  175 , and a screen  190 . The mobile terminal  100  may further include at least one of a mobile communication module  120 , a sub communication module  130 , a multimedia module  140 , a camera module  150 , an input/output module  160 , a sensor module  170 , a power supply unit  180 , and a screen controller  195 . 
     The controller  110  may include a Read Only Memory (ROM)  112  in which a control program for controlling the mobile terminal  100  is stored, and a Random Access Memory (RAM)  113  which memorizes a signal or data input from the mobile terminal  100  or is used as a memory region for a task performed in the mobile terminal  100 . A Central Processing Unit (CPU)  111  may include a single core, a dual core, a triple core, or a quad core processor. The CPU  111 , the ROM  112 , and the RAM  113  may be interconnected through an internal bus. 
     The controller  110  controls the mobile communication module  120 , the sub communication module  130 , the multimedia module  140 , the camera module  150 , the input/output module  160 , a Global Positioning System (GPS) module  155 , the sensor module  170 , the storing unit  175 , the power supply unit  180 , the screen  190 , and the screen controller  195 . 
     The controller  110  controls various contents displayed through the screen  190  or controls displaying of the contents by controlling the screen  190 . The controller  110  controls the mobile terminal  100  to perform an operation corresponding to a touch input detected through the screen  190 , that is, an operation corresponding to a user input. Upon inputting of a touch input of touching at least one point through the screen  190 , the controller  110  controls the mobile terminal  100  to perform an operation corresponding to the touch input. 
     According to an embodiment of the present disclosure, the controller  110  controls the mobile terminal  100  to execute the note function. Upon inputting of a user input for executing the note function through the input/output module  160  or the screen  190 , the controller  110  controls the screen  190  to display an execution screen on which the note function is executed. The controller  110  also controls the mobile terminal  100  to perform an operation corresponding to the user input inputted through the input/output module  160  or the screen  190  during execution of the note function. 
     In the current embodiment of the present disclosure, the note function for recording and storing at least one memo may be implemented in the form of software or an application stored in the storing unit  175  and may be executed by the controller  110 . For example, the user may select an application that implements the note function from among applications stored in the storing unit  175  of the mobile terminal  100  to execute the note function in the mobile terminal  100 . 
     The controller  110  may control the screen  190  to display notes, stored in advance in the storing unit  175 , based on attributes of the respective notes, upon execution of the note function in the mobile terminal  100 . The controller  110  may control the screen  190  to display the notes differently depending on a time having elapsed after creation of each note. For example, the controller  110  may control the screen  190  in such a way that a note having a longer elapsed time after creation has an older feeling. 
     The controller  110  also controls the screen  190  to display the notes differently depending on a cover attribute of each note. For example, the controller  110  may control the screen  190  to display the notes differently for leather, soft, and hard covers of the notes. According to an embodiment, the controller  110  may control the screen  190  to differently display the covers of the notes depending on a security level of each note. For example, the controller  110  may control the screen  190  to display a larger-size lock for a note having a higher security level and display a smaller-size lock for a note having a lower security level. According to another embodiment, the degree of transformation of objects (for example, a lock, and the like) included in each note may vary with a security level of the note. For example, suppose that a lock indicating that a note is protected is provided on a cover of the note and that the user inputs a user input for selecting the protected note to the mobile terminal  100 . In the current embodiment, the controller  110  may control the screen  190  to display a larger motion of the lock for a higher security level of the note. For example, a lock provided on a cover of a note sways 150° to the left and to the right for a high security level, 100° to the left and to the right for an intermediate security level, and 50° to the left and to the right for a low security level. 
     According to an embodiment of the present disclosure, the controller  110  controls the screen  190  to arrange and display the notes in line horizontally depending on attributes (for example, a cover attribute, an elapsed time after creation, a security level, and the like) of each note. Upon inputting of a user input for horizontally scrolling the notes through the screen  190 , the controller  110  controls the screen  190  to move and display the notes from the left to the right or from the right to the left, based on attributes of each note and an order the notes are arranged. According to another embodiment, the controller  110  controls the screen  190  to arrange and display the notes in line vertically. Upon inputting of a user input for vertically scrolling the notes through the screen  190 , the controller  110  controls the screen  190  to move and display the notes from top to bottom or from bottom to top, based on attributes of each note and an arranging order of the notes. 
     According to an embodiment of the present disclosure, once receiving, from the user, a touch input of selecting one of the horizontally arranged notes and dragging down the selected note through the screen  190 , the controller  110  may regard the touch input as a user input for selecting one of the horizontally arranged notes. 
     According to an embodiment of the present disclosure, the controller  110  controls the screen  190  to arrange and display the notes horizontally and display at least some sheets of each note in one of an upper portion, a lower portion, a left portion, and a right portion of the note. For example, the screen  190  may display, together with the horizontally arranged notes, some sheets of each note in an upper portion of the note. According to an embodiment of the present disclosure, the controller  110  controls the screen  190  to display sheets of a note selected by the user in one of the upper portion, the lower portion, the left portion, and the right portion of the note. Similar to the covers of the notes, the sheets may also be displayed differently depending on an elapsed time after creation of each sheet or attributes of each sheet. 
     According to an embodiment of the present disclosure, the controller  110  controls the screen  190  to display the note selected by the user by applying a different time for opening a cover of the selected note, depending on a material of the cover of the selected note or the number of sheets included in the selected note. For example, for a note including a larger number of sheets, a longer time may be needed to open a cover of the note, and for a note including a smaller number of sheets, a shorter time may be needed to open a cover of the note. In addition, for a heavier material of a cover, a longer time may be needed to open the cover. 
     As such, the controller  110  defines attributes of each note. By defining the attributes of each note, the controller  110  controls the screen  190  to display each note depending on the attributes of the note. If a note is selected by a user input, the controller  110  also controls the screen  190  to transform and display the selected note depending on attributes of the note and the user input. The controller  110  also defines attributes of each sheet of a note to display the sheet depending on the defined attributes of the sheet. If a user input is inputted for each sheet, the controller  110  controls the screen  190  to transform and display each sheet depending on the attributes of the sheet and the user input. 
     The mobile communication module  120  may facilitate the connection between the mobile terminal  100  and an external device by using one or more antennas (not illustrated) under control of the controller  110 .

The sensor module  170  detects a state of the mobile terminal  100  and generates a signal corresponding to the detection to output the signal to the controller  110 . The sensor of the sensor module  170  may be added or removed depending on the capability of the mobile terminal  100 . 
     The sensor module  170  may include a proximity sensor that detects user&#39;s motion (for example, motion of a finger of a user) detected in a range that is proximate to the screen  190 . For example, if the screen  190  is implemented as a capacitive type, the sensor module  170  implemented with a proximity sensor may detect a user&#39;s motion by detecting a capacitance change occurring in a range of the screen  190  (for example, at a height of  10  cm from the screen  190 ). The detected user&#39;s motion may also be included in a user input. 
     The power supply unit  180  supplies power to one or more batteries disposed in a housing of the mobile terminal  100  under control of the controller  110 . The one or more batteries supply power to the mobile terminal  100 . The power supply unit  180  may also supply power input from an external power source through the wired cable connected with the connector  165  to the mobile terminal  100 . The power supply unit  180  may also supply power, which is wirelessly input from an external power source using a wireless charging technique, to the mobile terminal  100 . 
     The screen controller  195  converts the analog signal received from the screen  190  into a digital signal and transmits the digital signal to the controller  110 . The controller  110  controls the screen  190  by using the digital signal received from the screen controller  195 . For example, the controller  110  may control a shortcut icon (not illustrated) displayed on the screen  190  to be selected or executed in response to a direct touch event or a hovering event. The screen controller  195  may be included in the controller  110 . 
     According to an embodiment of the present disclosure, the screen controller  195  may extract coordinates on the screen  190 , which correspond to a proximity detecting input detected by the sensor module  170 . For example, suppose that a proximity detecting input for selecting a point (a first point) in a range proximate to the screen  190  is detected through the sensor module  170 . In addition, suppose that proximity detecting is implemented as a capacitive type. The sensor module  170  detects a capacitance change occurring in a range of the screen  190 , and the controller  110  controls the screen controller  195  to extract coordinates of a point (a second point) on the screen  190 , which corresponds to a point (a first point) at which the capacitance change occurs. For example, the second point may be a point on the screen  190 , which is closest to the first point. 
     According to an embodiment of the present disclosure, the mobile terminal  100  may be connected with an external electronic device (not illustrated) by using at least one of the sub communication module  130 , the connector  165 , and the earphone connecting jack  167 .

       FIG. 4A  is a flowchart illustrating a method for operating a mobile terminal according to an embodiment of the present disclosure. 
     Referring to  FIG. 4A , the mobile terminal  100  receives a user input for executing a note function from a user in operation S 402 . According to an embodiment, the user may input a user input of selecting an application implemented to execute the note function from among applications stored in the storing unit  175 , thus inputting the user input for executing the note function to the mobile terminal  100 . 
     Once the user input for executing the note function is input, the controller  110  controls the mobile terminal  100  to execute the note function and display a note in operation S 404 . According to an embodiment of the present disclosure, the controller  110  displays the note by executing the application implemented to execute the note function and displaying the application on the screen  190 . When the note is displayed, the user may record desired data for addition or modification or may delete existing data. The controller  110  executes the note function and displays the note function on the screen  190  in real time based on the user input in operation S 406 . 
       FIG. 4B  is a flowchart illustrating a method for operating a mobile terminal according to an embodiment of the present disclosure. 
     Referring to  FIG. 4B , if the note function is executed in operation S 412 , the screen  190  of the mobile terminal  100  displays notes depending on attributes of each note under control of the controller  110  in operation S 414 . For example, it is assumed that first through third notes are displayed on the screen  190  in operation S 414 . In addition, suppose that an attribute of the first note is a leather cover, an attribute of the second note is a soft cover, and an attribute of the third note is a hard cover. In operation S 412 , the controller  110  controls the screen  190  to display the first through third notes in such a way that the user may see a material of the cover of each of the first through third notes. The attributes of each note may include a material of the cover, a color of the cover, a font of a title on the cover, a font size of the title on the cover, a material of a sheet, a color of the sheet, a font on the sheet, a font size on the sheet, and the like. 
     According to an embodiment of the present disclosure, prior to operation S 412 , the mobile terminal  100  may receive the user input for executing the note function from the user. According to an embodiment of the present disclosure, the user inputs a user input of selecting the application (note application) implemented to execute the note function from among the applications stored in the storing unit  175  of the mobile terminal  100 , thus inputting the user input for executing the note function to the mobile terminal  100 . 
     The controller  110  determines whether a user input for selecting one of the displayed notes is received in operation S 416 . If the controller  110  determines that the user input is not received in operation S 416  (‘No’), the screen  190  continues displaying the notes depending on the attributes of the respective notes, under control of the controller  110  in operation S 414 . 
     If the controller  110  determines that the user input is received in operation S 416  (‘Yes’), the screen  190  displays sheets included in the selected note under control of the controller  110  in operation S 418 . 
       FIGS. 5A ,  5 B, and  5 C illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
     Referring to  FIGS. 5A ,  5 B, and  5 C, it is illustrated that first, second, and third notes  510 ,  520 , and  530  are thicker in that order. For example, the first note  510  illustrated in  FIG. 5A  has the smallest thickness, the third note  530  illustrated in  FIG. 5C  has the largest thickness, and the second note  520  illustrated in  FIG. 5B  has a thickness larger than the thickness of the first note  510  and smaller than the thickness of the third note  530 . 
     Once the note function is executed, the screen  190  displays the first, second, and third notes  510 ,  520 , and  530 , as illustrated in  FIGS. 5A ,  5 B, and  5 C under control of the controller  110 . The screen  190  may also receive a user input for turning over a cover or a sheet of each of the first through third notes  510 ,  520 , and  530  from the user. 
     Referring to  FIG. 5A , the mobile terminal  100  first displays the first note  510  having a small thickness and receives a user input for turning over a cover  511  of the first note  510  through the screen  190 . The mobile terminal  100  performs and displays an action of turning the cover  511  of the first note  510  on the screen  190 . The cover  511  of the first note  510  is assumed to have a small thickness (of, for example, 1 mm or less). When executing and displaying the action of turning the cover  511  of the first note  510  on the screen  190 , the controller  110  may give the user an impression that the thin cover  511  is lightly turned over. For example, under control of the controller  110 , the screen  190  may perform a display operation as if the cover  511  of the first note  510  is turned over in a fluttering manner. 
     Referring to  FIG. 5B , the mobile terminal  100  first displays the second note  520  having an intermediate thickness, which is thicker than the first note  510  and thinner than the third note  530 , and receives a user input for turning a cover  521  or a sheet  522  of the second note  520  through the screen  190 . The mobile terminal  100  performs and displays an action of turning the cover  521  of the second note  520  on the screen  190 . The cover  521  of the second note  520  has an intermediate thickness (of, for example, about 1-2 mm), and thus is thicker than the cover  511  of the first note  510  and is thinner than a cover  531  of the third note  530 . When performing and displaying the action of turning the cover  521  of the second note  520  on the screen  190 , the controller  110  may give the user an impression that the cover  521  is turned over more heavily than the cover  511  of the first note  510 . According to an embodiment of the present disclosure, the sheet  522  of the second note  520  is assumed to be thinner (to have a thickness of, for example, about 1 mm or less) than the cover  521  of the second note  520 . Thus, when performing and displaying the action of turning the sheet  522  of the second note  520  on the screen  190 , the controller  110  may give the user an impression that the thin cover  511  is lightly turned over. For example, the screen  190  may perform a display operation as if the sheet  522  of the second note  520  is turned over in a fluttering manner. 
     Referring to  FIG. 5C , the mobile terminal  100  first displays the third note  530  having a large thickness and receives a user input for turning the cover  531  of the third note  530  through the screen  190 . The mobile terminal  100  performs and displays an action of turning the cover  531  of the third note  530  on the screen  190 . The cover  531  of the third note  530  is assumed to have a large thickness (of, for example, about 3 mm or more). When performing and displaying the action of turning the cover  531  of the third note  530  on the screen  190 , the controller  110  may give the user an impression that the thick cover  531  is heavily turned over. For example, the screen  190  may perform a display operation as if the cover  531  of the third note  530  is heavily turned over, under control of the controller  110 . 
     According to an embodiment of the present disclosure, the controller  110  may apply different times during which the first, second, and third covers  511 ,  521 , and  531  of the first, second, and third notes  510 ,  520 , and  530  are turned over or opened, for different thicknesses of the first, second, and third covers  511 ,  521 , and  531 . For example, the controller  110  may control the screen  190  to display the first, second, and third covers  511 ,  521 , and  531  of the first, second, and third notes  510 ,  520 , and  530 , such that  0 . 5  second is taken to open the cover  511  of the first note  510 , 1 second is taken to open the cover  521  of the second note  520 , and 1.5 seconds are taken to open the cover  531  of the third note  530 . According to an embodiment of the present disclosure, the controller  110  may apply different actions of turning the first, second, and third covers  511 ,  521 , and  531  for different types of the first, second, and third covers  511 ,  521 , and  531 . For example, suppose that the cover  511  of the first note  510  is a soft cover, the cover  521  of the second note  520  is a hard cover, and the cover  531  of the third note  530  is a leather cover. The controller  110  may control the screen  190  or the screen controller  195  to display the texture of each of the first, second, and third covers  511 ,  521 , and  531 . The controller  110  may also control the screen  190  or the screen controller  195  to display the actions of turning the first, second, and third covers  511 ,  521 , and  531  differently depending on the textures of the first, second, and third covers  511 ,  521 , and  531 . 
     Although the actions of turning the first, second, and third covers  511 ,  521 , and  531  or the sheet  522  of the first, second, and third notes  510 ,  520 , and  530  are executed and displayed based on a user input in  FIGS. 5A ,  5 B, and  5 C, according to another embodiment, the mobile terminal  100  may also execute and display the actions of turning the first, second, and third covers  511 ,  521 , and  531  of the first, second, and third notes  510 ,  520 , and  530  or the sheet  522 , upon elapse of a reference time. For example, if 30 seconds have passed after execution of the note function, the controller  110  may control the mobile terminal  100  to turn the first, second, and third covers  511 ,  521 , and  531  of the first, second, and third notes  510 ,  520 , and  530  or the sheet  522 , even when a user input is not inputted. 
       FIGS. 6A ,  6 B, and  6 C illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure.  FIGS. 6A ,  6 B, and  6 C show notes displayed differently based on how much the user has used the note function of the mobile terminal  100 . 
     Referring to  FIG. 6A , a first note  610  is a newly created note. Upon execution of the note function, the user determines whether to create a new note. If a user input for creating a new note is input, the controller  110  controls the screen  190  to display the newly created note, that is, the first note  610  as illustrated in  FIG. 6A . As illustrated in  FIG. 6A , the first note  610  may be implemented to include a cover  611  and may be displayed on the screen  190 . According to an embodiment of the present disclosure, the mobile terminal  100  may add a sheet to the first note  610  based on a user input, and the added sheet may also be included in the first note  610 . 
     Referring to  FIG. 6B , a second note  620  is a note whose one sheet  622  has already been used by the user. Upon execution of the note function, the user determines whether to display a previously used note on the screen  190 . Upon inputting of a user input for displaying the previously used note on the screen  190 , the controller  110  controls the screen  190  to display the previously used note, that is, a second note  620  as illustrated in  FIG. 6B . In  FIG. 6B , it is assumed that a user input for displaying the second note  620  whose sheet  622  has already been used on the screen  190  is input. Thus, the second note  620  may be implemented to include a cover  621  and the sheet  622  and may be displayed on the screen  190 . According to an embodiment of the present disclosure, the mobile terminal  100  may add at least one sheet to the second note  620  based on a user input, and the added sheet may also be included in the second note  620 . 
     Referring to  FIG. 6C , a third note  630  is a note whose two sheets  632  and  633  have already been used by the user. Upon execution of the note function, the user determines whether to display a previously used note on the screen  190 . If a user input for displaying the previously used note on the screen  190  is input, the controller  110  may control the screen  190  to display the previously used note, that is, the third note  630  as illustrated in  FIG. 6C . Like in  FIG. 6B , also in  FIG. 6C , it is assumed that a user input for displaying the third note  630  whose two sheets  622  and  623  have already been used by the user on the screen  190  is input. Thus, the third note  630  may be implemented to include a cover  631  and the two sheets  632  and  633  and may be displayed on the screen  190 . According to an embodiment of the present disclosure, the mobile terminal  100  may add at least one sheet to the third note  630  based on a user input, and the added sheet may also be included in the third note  630 . 
     While parts of the sheets  622 ,  632 , and  633  of the notes  620  and  630  are shown on upper ends of the notes  620  and  630  in  FIGS. 6B and 6C , according to another embodiment, the parts of the sheets  622 ,  632 , and  633  may also be shown in left, right, or lower portions of the notes  620  and  630 . 
       FIGS. 7A and 7B  illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure.  FIG. 7A  illustrates an execution screen appearing on the screen  190  immediately after the note function is executed by the mobile terminal  100 , and  FIG. 7B  illustrates an execution screen appearing after one of multiple notes is selected by the user. 
     Referring to  FIG. 7A , upon execution of the note function, at least one notes stored in advance by the user are displayed on the screen  190 . It is assumed that three first through third notes  810 ,  820 , and  830  are stored in advance. The mobile terminal  100  receives a user input for selecting a note from the user. The user is assumed to select the first note  810 . To select the first note  810 , the user touches and then dragging down at least a part or a lower portion of the first note  810  in the direction of an arrow  860 , thus inputting a user input ( 1 ) for selecting the first note  810  to the mobile terminal  100 . Although not shown in  FIG. 7A , the first note  810  may be displayed on the screen  190  in the form of being dragged down based on the user input ( 1 ). 
       FIG. 7B  illustrates a state after one of the first, second, and third notes  810 ,  820 , and  830  illustrated in  FIG. 7A  is selected. 
     Referring to  FIG. 7B , once a particular note, for example, the first note  810  here, is selected, the first note  810  is positioned in a lower portion of the screen  190 . Above the selected note  810 , sheets included in the note  810  may be sequentially arranged. In  FIG. 7B , sheets  811  and  812  included in the first note  810  are displayed above the first note  810  selected by the user. An additional page  813  for adding a new sheet may be provided after the last sheet of the note  810 . Thus, the user may add a sheet to the first note  100  by inputting a user input for selecting the additional page  813  to the mobile terminal  100 . 
     The execution screens illustrated in  FIGS. 7A and 7B  may be consecutively displayed on the screen  190 . For example, upon inputting of the user input for executing the note function from the user, the mobile terminal  100  displays the execution screen on which the first note  810 , the second note  820 , and the third note  830  are arranged as illustrated in  FIG. 7A . The user selects one point on the screen  190 , and in this state, slides the screen  190  to the left or right, thus situating one of the first, second, and third notes  810 ,  820 , and  830  in the center of the screen  190 . The user may also select and drags down one point included in one of the first, second, and third notes  810 ,  820 , and  830 , thus selecting a corresponding note and at the same time, displaying sheets included in the selected note on the screen  190 . In  FIGS. 7A and 7B , the first note  810  is selected by the user input and the user drags down the first note  810  to the lower portion of the screen  190 , thus inputting the user input ( 1 ) for selecting the first note  810  to the mobile terminal  100 . The mobile terminal  100  situates the first note  810  in the lower portion of the screen  190  in real time based on the user input ( 1 ), and also displays the sheets  811  and  812  included in the first note  810  and the additional page  813  above the first note  810 , allowing the user to intuitively recognize the sheets  811  and  812  included in the first note  810 . 
       FIGS. 8A ,  8 B, and  8 C illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
     Referring to  FIGS. 8A ,  8 B, and  8 C, first, second, and third notes  910 ,  920 , and  930  are displayed differently depending on the number of sheets included in each of the first, second, and third notes  910 ,  920 , and  930 . In  FIG. 8A , the first note  910  does not include any sheet and the first note  910  is displayed. In  FIG. 8B , the second note  920  includes one sheet  922  and a part of the sheet  922  is displayed on an upper portion of a cover  921 . In  FIG. 8C , the third note  930  includes two sheets  932 , and like in the second note  920  of  FIG. 8B , parts of the sheets  932  are displayed on an upper portion of a cover  931 . On an execution screen on which the note function is executed, the mobile terminal  100  may implement and display the number of sheets included in each of the first, second, and third notes  910 ,  920 , and  930  as illustrated in  FIGS. 8A ,  8 B, and  8 C. Hence, the user executing the note function may intuitively recognize the number of sheets included in each of the first, second, and third notes  910 ,  920 , and  930 . 
     Although the two sheets  932  are included in the third note  930  in  FIG. 8C , three or more sheets may be displayed overlappingly like the sheets  932  illustrated in  FIG. 8C , and sheets more than a set number of sheets may not be displayed. For example, suppose that the number of sheets included in a note is 10. Thereafter, the controller  110  may overlappingly display some of the sheets, for example, three sheets, on an upper portion of the note, and display a number ‘10’ in a left or right portion of the upper portion of the note, thus indicating that a total of 10 sheets are included in the note. 
       FIGS. 9A ,  9 B, and  9 C illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
     In  FIGS. 9A ,  9 B, and  9 C, the user may be given an impression that sheets  1012 ,  1022 , and  1032  included in first, second, and third notes  1010 ,  1020 , and  1030 , respectively, are aged over time. 
     Referring to  FIGS. 9A ,  9 B, and  9 C, the controller  110  display the sheets  1012 ,  1022 , and  1032  as being more discolored or worn out as they were created a longer time ago. In  FIGS. 9A ,  9 B, and  9 C, the third note  1030 , the second note  1020 , and the first note  1010  are sequentially created in that order and are stored in the mobile terminal  100 . 
     In  FIG. 9A , the first note  1010  is a newly created note, or a first reference time (for example,  7  days) has not yet been passed since the first note  1010  was created. Thus, the sheets  1012  of the first note  101  are displayed as being neither discolored nor worn out on the screen  190 . 
     In  FIG. 9B , the first reference time (for example, 7 days) has passed, but a second reference time (for example, 30 days) has not yet been passed, since the second note  1020  was created. Thus, the sheets  1022  of the second note  1020  are displayed as being discolored on the screen  190  in comparison to the sheets  1012  of the first note  1010 . 
     In  FIG. 9C , the second reference time (for example,  30  days) has passed since the third note  1030  was created. Thus, the sheets  1032  of the third note  1030  are displayed as much discolored and worn out on the screen  190  in comparison to the sheets  1012  and  1022  of the first and second notes  1010  and  1020 . 
     Referring to  FIGS. 9A ,  9 B, and  9 C, covers  1011 ,  1021 , and  1031  of the first, second, and third notes  1010 ,  1020 , and  1030  may maintain their original states of being created, irrespective of time. According to another embodiment of the present disclosure, the covers  1011 ,  1021 , and  1031  of the first, second, and third notes  1010 ,  1020 , and  1030  may also be transformed over time. 
     According to an embodiment of the present disclosure, the first reference time and the second reference time may be set by the controller  110 . The first reference time and the second reference time may be determined by a user input inputted through the input/output module  160  or the screen  190 . According to another embodiment, sheets of a note may be displayed differently depending on a third reference time, a fourth reference time, . . . , and an Nth reference time (N is a natural number), as well as the first and second reference times, over time. 
       FIGS. 10A ,  10 B,  10 C, and  10 D illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure.  FIG. 10A  illustrates an execution screen on which a security-reinforced note is executed, and  FIGS. 10B ,  10 C, and  10 D illustrate a lock as an example indicating a security level of the note. 
     Referring to  FIG. 10A , a first note  1110 , a second note  1120 , and a third note  1130  are displayed on the screen  190  as an execution screen on which the note function is executed. The first note  1110  is selected by the user from among the first, second, and third notes  1110 ,  1120 , and  1130 . The user selects and drags down a point on the first note  1110  or a point in a lower portion of the first note  1110  in the direction of an arrow  1140 , and the controller  110  receives such a user&#39;s action as a user input for selecting the first note  1110  on the screen  190 . 
     Suppose that the first note  1110  has a high security level. A note having a high security level may be implemented as being locked by a lock  1150  as illustrated in  FIG. 10A . 
     Referring to  FIGS. 10B ,  10 C, and  10 D, first, second, and third locks  1151 ,  1152 , and  1153  are implemented to have different gradients for different security levels. For example, the first lock  1151  may have a low security level, the second lock  1152  may have an intermediate security level, and the third lock  1153  may have a high security level. According to another embodiment of the present disclosure, the first lock  1151  may have a high security level, the second lock  1152  may have an intermediate security level, and the third lock  1153  may have a low security level. However, it is noted that the illustration of the security level is not limited to an icon of a lock and icons of different forms, shapes, and colors may be used. 
     The security level of the lock  1150  may be determined depending on an input form or length of a password for executing the first note  1110 . For example, if the input form of the password includes numbers, the controller  110  determines that a security level is low, and if the input form of the password is a combination of numbers and characters, the controller  110  determines that a security level is high. If the input form of the password is a pattern drawn by the user, a security level of the pattern may be higher than that of a number password. The controller  110  determines a higher security level for a longer number password or a longer number-character password. Similarly, for a more complex pattern, a higher security level may be determined. 
     The controller  110  may control the screen  190  to display contents, for example, sheets, included in the first note  1110  when a password is input by the user. According to an embodiment of the present disclosure, if the first note  1110  locked by the lock  1150  is selected by the user, the controller  110  may control the screen  190  to display an input window for receiving a password above the first note  1110  or separately from the first note  1110 . If a correct password is input from the user, the controller  110  controls the screen  190  to display an execution screen on which the lock  1150  of the first note  1110  is opened. 
       FIGS. 11A ,  11 B, and  11 C illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
     Referring to  FIGS. 11A ,  11 B, and  11 C, if a note  1210  has not been updated for a reference time (for example,  30  days) or more, the controller  110  controls the screen  190  to display the note  1210  as having dust  1250  or a stain (not illustrated) on the surface thereof as illustrated in  FIG. 11A . The reference time may be a set value or may be input from a user  1200  through the input/output module  160  or the screen  190 . However, it is noted that other types of icons, notifications, and the like, may be used to indicate the reference time. 
     According to an embodiment of the present disclosure, the controller  110  controls the screen  190  to display the note  1210  after adjusting the density of the dust  1250  on the surface of the note  1210  based on a non-update time. For example, if the note  1210  has not been updated for 0-7 days, the controller  110  may control the screen  190  to display the note  1210  as having no dust  1250  on the surface thereof. If the note  1210  has not been updated for 8-14 days, the controller  110  may control the screen  190  to display the note  1210  as having the dust  1250  in a region corresponding to ⅓ of the surface of the note  1210 . If the note  1210  has not been updated for 15-21 days, the controller  110  may control the screen  190  to display the note  1210  as having the dust  1250  in a region corresponding to ⅔ of the surface of the note  1210 . If the note  1210  has not been updated for  22  days or more, the controller  110  may control the screen  190  to display the note  1210  as having the dust  1250  on the entire surface of the note  1210  as illustrated in  FIG. 11A . 
     Once the note  1210  having the dust  1250  because of not being updated as illustrated in  FIG. 11A  is selected by the user  1200 , the dust  1250  may be stirred up and removed from the surface of the note  1210  as illustrated in  FIGS. 11A and 11B . As illustrated in  FIG. 11B , upon selection of the note  1210  by the user  1200 , the controller  110  may control the screen  190  to display an image showing that the dust  1250  on the surface of the note  1210  flies and disappears from the surface of the note  1210 .  FIG. 11B  shows an execution screen immediately after a user input for selecting the note  1210  is input by the user  1200 , in which the user  1200  touches the surface of the note  1210  displayed on the screen  190 .  FIG. 11C  shows an execution screen immediately after the user input illustrated in  FIG. 11B  is input, on which the dust  1250  is removed from the surface of the note  1210 . 
     As such, the mobile terminal  100  may visually indicate to the user  1200  that the note  1210  is updated or is not updated by displaying the dust  1250  piled on the surface of the note  1210 . 
       FIGS. 12A ,  12 B,  12 C, and  12 D illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
       FIGS. 12A ,  12 B,  12 C, and  12 D show execution screens  1300  when one of multiple notes  1310 ,  1320 ,  1330 ,  1340 , and  1350  is selected during execution of the note function of the mobile terminal  100 . 
     Referring to  FIG. 12A , the controller  110  controls the screen  190  to display a first note  1310 , a second note  1320 , a third note  1330 , a fourth note  1340 , and a fifth note  1350  in a lower portion, that is, a first region  1301 , of an execution screen  1300  on which the note function is executed. The controller  110  controls the screen  190  to display a note primarily selected by the user from among the first, second, third, fourth, and fifth notes  1310 ,  1320 ,  1330 ,  1340 , and  1350  displayed on the first region  1301  in an upper portion, that is, a second region  1302 , of the execution screen  1300 . In  FIG. 12A , the fourth note  1340  is primarily selected by the user from among the first, second, third, fourth, and fifth notes  1310 ,  1320 ,  1330 ,  1340 , and  1350 , such that the fourth note  1340  is displayed enlarged in the second region  1302  in  FIGS. 12A and 12B . 
     Referring to  FIG. 12B , the mobile terminal  100  receives a user input ( 2 ) for receiving another selection of the fourth note  1340  from the user. The user input ( 2 ) is assumed to be input by the user touching a point on the fourth note  1340  displayed in the second region  1302  and dragging down the point in the direction of an arrow  1360  as illustrated in  FIG. 12B . 
     Referring to  FIG. 12C , upon inputting of the user input ( 2 ) as illustrated in  FIG. 12B , the second region  1302  is enlarged and at the same time the fourth note  1340  is also enlarged. The lower portion, that is, the first region  1301 , of the execution screen  1300  and the first, second, third, fourth, and fifth notes  1310 ,  1320 ,  1330 ,  1340 , and  1350  included in the first region  1301  may be partially hidden by the second region  1302 . According to an embodiment of the present disclosure, the user may adjust the size of the second region  1302  in real time based on the user input ( 2 ) of dragging in the direction of the arrow  1360 . The size of the second region  1302  and the size of the fourth note  1340  included in the second region  1302  increase as the user drags the execution screen  1300  in the direction of the arrow  1360 , and decrease as the user drags the execution screen  1300  in a direction opposite to the arrow  1360 . 
     Referring to  FIG. 12D , it illustrates a result of the user dragging the execution screen  1300  in the direction of the arrow  1360  until the second region  1302  entirely covers the first region  1301 , as the user input ( 2 ) illustrated in  FIG. 12B . If the first region  1301  disappears from the execution screen  1300  as illustrated in  FIG. 12D , the controller  110  regards the fourth note  1340  as being finally selected by the user. Thus, the controller  110  displays sheets  1341  included in the fourth note  1340  on an upper portion of the fourth note  1340 . 
       FIGS. 13A ,  13 B,  13 C,  13 D, and  13 E illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
       FIGS. 13A ,  13 B,  13 C,  13 D, and  13 E show execution screens on which the note function is executed to modify a sheet included in at least one note. 
     Referring to  FIG. 13A , the execution screen displayed on the screen  190  is divided into a first region  1401  and a second region  1402 . The first region  1401  includes a note  1410  selected by the user and the second region  1402  includes first and second sheets  1411  and  1412  included in the selected note  1410 . In  FIG. 13A , the first sheet  1411  and the second sheet  1412  included in the note  1410  are shown. 
     Referring to  FIG. 13B , the mobile terminal  100  receives a user input ( 3 ) for selecting the second sheet  1412  from the user. The user may touch a point on the second sheet  1412  to select the second sheet  1412  on the execution screen displayed on the screen  190 . Upon selection of the second sheet  1412  as in  FIG. 13B , the controller  110  controls the screen  190  to display the second sheet  1412  over the entire screen  190 . 
     Referring to  FIG. 13C , the second sheet  1412  is displayed as the execution screen over the entire screen  190 . Afterwards, the user inputs a user input ( 4 ) for modifying the second sheet  1412  to the mobile terminal  100 . 
     Referring to  FIGS. 13D and 13E , the mobile terminal  100  receives the user input ( 4 ) requesting modification of the second sheet  1412  from the user, in which the user input ( 4 ) is inputted by the user touching a point on the second sheet  1412  displayed over the entire screen  190 . Upon inputting of the user input ( 4 ), the controller  110  displays various tools  1431 ,  1432 ,  1433 ,  1435 ,  1436 , and  1437  for modifying the second sheet  1412  on the second sheet  1412 , as illustrated in  FIG. 13E . 
       FIGS. 14A ,  14 B,  14 C, and  14 D illustrate a mobile terminal executing a note function according to an embodiment of the present disclosure. 
       FIGS. 14A ,  14 B,  14 C, and  14 D show execution screens for executing the note function on which sheets included in at least one note are displayed. Referring to  FIG. 14A , the execution screen is divided into a first region  1501  and a second region  1502 . The first region  1501  includes a note  1510  selected by the user, and the second region  1502  includes first, second, third, fourth, and fifth sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  included in the selected note  1510 .  FIG. 14A  shows the first sheet  1511 , the second sheet  1512 , the third sheet  1513 , the fourth sheet  1514 , and the fifth sheet  1515  included in the note  1510 . 
     Referring to  FIGS. 14A ,  14 B,  14 C, and  14 D, the mobile terminal  100  receives a user input for increasing the size of the second region  1502  from the user. For example, the user may input a user input ( 5 ) to the mobile terminal  100  by touching and then dragging down a point on the first region  1501  or a point on the note  1510  in the direction of an arrow  1561 . Based on the user input ( 5 ), the controller  110  increases the size of the second region  1502  and reduces the size of the first region  1501  on a real time basis. The controller  110  may increase or reduce the size of the first region  1501  and the size of the second region  1502  until inputting of the user input ( 5 ) ends. The user input ( 5 ) may end when the user does not select the point on the first region  1502  any longer. For example, the user may start inputting the user input ( 5 ) by touching a point on the first region  1501  with a finger (or an input unit, such as a stylus pen) and may finish inputting the user input ( 5 ) by removing the finger (or the input unit) from the point. The user may increase or reduce the size of the first region  1501  and the size of the second region  1502  by selecting a point and in this state, dragging the execution screen up or down as desired by the user.  FIGS. 14A ,  14 B, and  14 C shows that the size of the first region  1501  is reduced and the size of the second region  1502  is increased based on the user input ( 5 ). In this case, the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  arranged in line may be displayed enlarged in proportional to the enlargement of the second region  1502 . 
     Referring to  FIGS. 14A ,  14 B, and  14 C, it can be seen that the sizes of the arranged sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  are increased as the size of the second region  1502  is increased. 
     The mobile terminal  100  may then receive a user input ( 6 ) for selecting one of the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  included in the note  1510 . In  FIG. 14C , the mobile terminal  100  receives the user input ( 6 ) for selecting a point on the third sheet  1513 . The user may input the user input ( 6 ) by selecting and then dragging the point on the third sheet  1513  in the direction of an arrow  1562 , that is, from the right to the left, thus scrolling the sheets  1511 ,  1512 ,  1513 ,  514 , and  1515  arranged in line.  FIG. 14D  shows the execution screen on which the third sheet  1513  located in the center of the second region  1502  is moved to the left and the fourth sheet  1514  is located in the center of the second region  1502 , based on the user input ( 6 ). The user may input a user input ( 7 ) by selecting and then dragging the point on the fourth sheet  1514  located in the center of the second region  1502  to the right in the direction of an arrow  1563  and situating the third sheet  1513  in the center of the second region  1502 . As such, by executing the note function according to the current embodiment, the sizes of the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  included in the note  1510  are increased or reduced as desired by the user, and the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  arranged in line may be scrolled from the left to the right or from the right to the left based on the user input ( 6 ) or ( 7 ). Hence, the user may conveniently select a desired sheet. 
     Although the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  arranged horizontally are scrolled from the left to the right or from the right to the left in the current embodiment, they may also be arranged vertically according to another embodiment of the present disclosure. When the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  are arranged vertically, the mobile terminal  100  may receive a user input for scrolling the sheets  1511 ,  1512 ,  1513 ,  1514 , and  1515  up or down.
