The present invention relates to a mobile communication terminal having an input device, and more particularly, to a mobile communication terminal having an input device capable of inputting a command by a user's operation.

BACKGROUND Electronic devices such as mobile communication terminals use keypads for inputting certain information, such as numbers and letters.

Such a keypad is a push type input device in which switching is generated as a user pushes, so that a desired signal is input to an electronic device. Such a pressing method may be convenient in an operation of selecting one menu.

However, in the process of scrolling a plurality of menus as a previous step for selecting any one of a plurality of menus arranged in a row, the keypad should be pressed as much as a menu to be moved for moving between adjacent menus.

This repetitive pressing operation is cumbersome for the user, and the impact caused by the pressing operation is repeatedly acted on an electronic device such as a mobile communication terminal to hinder its mechanical stability.

Therefore, in place of the push-type input device as described above, the user can easily scroll through a plurality of menus while also reducing the impact on the device to which the new type of input device and a mobile communication terminal having the same. The need for this is constantly being raised.

SUMMARY OF THE INVENTION The present invention has been made in view of the above necessity, and an object of the present invention is to provide a mobile communication terminal having an input device for easily scrolling a plurality of menus with a simple operation and having less impact on other devices. do.

In order to achieve the above object, the input device according to an aspect of the present invention comprises a body, a main input roller and a rotation input unit.

The body may be a target to which the main input roller is mounted, and may be an independent member or a part of an electronic device such as a mobile communication terminal. The main input roller is rotatably mounted on the body. The rotation input unit is mounted between the main input roller and the body to receive the rotation direction of the main input roller as the user rotates the main input roller clockwise or counterclockwise. When the input rotation direction is matched with a direction for scrolling a plurality of menus displayed on a display unit such as a display mounted on a body, the menu can be easily scrolled by simply rotating the main input roller.

Furthermore, in order to prevent slipping in the process of rotating the main input roller, an anti-slip portion having an uneven shape may be formed on the outer circumference of the main input roller.

The rotation input unit may include a rotation pattern and a pattern sensing unit to determine the rotation direction of the main input roller. The rotation pattern may be an energization pattern composed of an energized part and a non-energized part, or a magnet part in which N poles and S poles are alternately arranged, and the pattern detecting part may include a plurality of contacts to which a current for sensing the energizing pattern is applied. It may be a plurality of sensors for detecting a magnetic flux change of the magnet part, for example, a hall sensor. Output through a plurality of contacts or sensors of the pattern detecting unit has a constant phase difference from each other, from which a different signal pattern according to the clockwise or counterclockwise rotation is generated, the control unit can determine the rotation direction of the main input roller based on this Will be.

Furthermore, the main input roller may further include an input function by a pressing operation in addition to the input function by rotation. Accordingly, when a menu to be selected is activated in a process of rotating the main input roller to scroll a plurality of menus, the main input roller can be immediately pressed to select the menu. The push input function requires a signal board mounted on the body and a switch formed on the signal board, and in some cases, an interlocking rod for interlocking the main input roller and the switch is required.

In addition, the click feeling providing unit provides a click feeling as the main input roller is rotated. To this end, the click feeling providing unit includes a movable cam having a movable protrusion, a fixed cam having a fixed protrusion corresponding to the movable protrusion, and an elastic body for pressing the movable cam toward the fixed cam. The fixed cam rotates together with the main input roller, and the movable cam is fixed to the body and does not rotate but slides along the rotation axis of the main input roller. On the contrary, it is also possible that the fixed cam is fixed to the body and the movable cam is mounted on the main input roller to rotate with it. Accordingly, the movable protrusion of the movable cam is pressed by the elastic body to advance toward the fixed cam and generates a click feeling while repeating the process of being retracted by the fixed protrusion.

Furthermore, the input device according to an aspect of the present invention may further include at least one sub input roller together with the main input roller in the input device configured as described above.

For such a sub input roller, only the push input unit is provided among the above rotation input unit and the push input unit provided for the main input roller. Accordingly, as the main input roller rotates, the main input roller functions to scroll the menu and selects the menu activated by the push input, and the sub input roller plays only the intermittent scroll function of the menu by the push input. .

Furthermore, when the main input roller is responsible for scrolling the menu in one direction (by rotating) and selecting a particular menu (by pressing), the sub-input roller is in the other direction (for example, the above work). It can be responsible for the scroll function (by pressing) of the menu in a direction perpendicular to the direction. In order to achieve the scroll function on both sides of the vertical direction above, the sub input roller is preferably composed of a first sub input roller and a second sub input roller.

In addition, in the assembly of the main input roller and the sub-input roller as described above, it is preferable to further include a chain portion to surround them and rotate at the same time. Through such a chain part, the main input roller and the sub input roller are interlocked and rotated at the same time regardless of which point the user rotates the chain part.

In this case, however, the input by rotation is input only by the main input roller and the rotation input unit provided thereto. Although the main input roller and the sub input roller are wrapped by the chain part, the input to each input roller is made separately. As described above, the push input for the main input roller causes the selection of the activated menu to be made, and the push input for the sub input roller is equivalent to the scrolling of the menu. Furthermore, it is possible to form such a chain portion is formed in an integral form, a plurality of chain pieces are fastened to form an integral.

The mobile communication terminal according to another aspect of the present invention comprises a terminal body and an input device mounted to expose the input rollers described above to the outside. To this end, the terminal body includes an upper cover and a lower cover forming an inner space, and the body on which the input rollers described above are supported is mounted in the inner space. Furthermore, it is preferable to form the same structure as the above body in the terminal body, for example, the lower cover itself, in terms of simplifying the manufacturing and assembly process.

Since the above input device is mounted on the terminal body of the mobile communication terminal, when scrolling a plurality of menus, a plurality of menus can be easily and quickly scrolled by rotating the main input roller without repeatedly pressing the input device. . This rotational input method also has the advantage of reducing the amount of impact on the terminal body on which the input device is mounted.

A mobile communication terminal having such an input device will be described herein using a slide type mobile communication terminal as an example, but this is only an example and the present invention is not limited thereto. In other words, it will be readily understood by those skilled in the art that the present invention can be applied to any type of mobile communication terminal such as bar type, clam type, swivel type.

Hereinafter, an input device and a mobile communication terminal having the same according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an input device according to an embodiment of the present invention, Figure 2 is an exploded perspective view showing a specific configuration of FIG.

As illustrated in the drawings, the input device according to an embodiment of the present invention includes a body 10, a main input roller 20, and a rotation input unit 30.

The body 10 includes a pair of side support parts 11 disposed to correspond to each other, and a support rod 13 connecting the pair of side support parts 11 to each other. Furthermore, the pair of side support portions 11 may have a form connected through the base portion 15 (see FIG. 6) disposed in a direction perpendicular thereto.

The main input roller 20 has a circular cross section and has a trunk portion 21 extending in the longitudinal direction, and a rotating shaft 23 protruding from both ends of the trunk portion 21 to be rotatably inserted into the side support portion 11. ). Further, the outer periphery of the body portion 21 may be formed with a non-slip portion 25 of the irregular shape. The non-slip part 25 is configured to prevent the user's finger from slipping when the body part 21 is rotated, and has a shape of a plurality of grooves extending in the longitudinal direction of the body part 21. However, the slipper 25 is not necessarily limited to the shape of the groove, and may be formed to protrude from the body portion 21.

The rotation input unit 30 is formed between the main input roller 20 and the body 10, specifically, the side support part 11, and receives the rotation direction of the main input roller 20. To this end, the rotation input unit 30 includes a rotation pattern and a pattern detecting unit.

The rotation input unit 30 according to the first embodiment of the present invention is composed of a rotation pattern composed of an energization pattern 31 and a pattern sensing unit composed of a contact portion 33 and a controller (not shown).

The energization pattern 31 is printed on one side of the main input roller 20 (one side of the fixed cam 53 coupled to one side of the main input roller 20 in FIG. 2), or separately the main input roller 20. ) Is printed on an energizing plate 31 'which is coupled to rotate therewith. The contact part 33 is coupled to the side support part 11 of the body 10 to be in contact with the conduction pattern 31 and is electrically connected to the control part. This will be described in more detail with reference to FIG. 3.

As illustrated in the figure, the conduction pattern 31 is a continuous conduction portion 31a formed so that electricity is energized at the center of one surface of the conduction plate 31 'and the conduction portion surrounding the continuous conduction portion 31a. 31ba and the non-conduction part 31bb include the selection electrification part 31b formed by turns.

The contact portion 33 is a ground contact 33a mounted to the body 10 to contact the continuous conduction portion 31a, and a positive contact 33b mounted to the body 10 to contact the selective conduction portion 31b. And a negative contact 33c. A positive current is applied to the positive contact 33b, and a negative current is applied to the negative contact 33c. These plus currents and negative currents are applied by the controller, and the positive or negative currents respectively output currents in the positive or negative states when the positive contact 33b and the negative contact 33c are in contact with the non-conductive part 31bb. When the positive contact 33b and the negative contact 33c come into contact with the energization part 31ba, respectively, as the energization pattern 31 is rotated, both of them are energized with the ground contact 33a and are in a ground state. In addition, the positive contact 33b and the negative contact 33c are spaced apart at regular intervals so that the waveforms of the currents output from the positive contact 33b and the negative contact 33c have a constant phase difference in accordance with the rotation of the energization pattern 31. Are left in place.

The controller determines the rotation direction of the main input roller 20 based on the waveform of the current output from the positive contact 33b and the negative contact 33c.

The rotation input unit 30 according to the second embodiment of the present invention includes a magnet unit 37 as a rotation pattern and a sensor unit 39 as a pattern sensing unit. This will be described with reference to FIG. 4.

4 is a conceptual diagram illustrating an arrangement relationship of the second embodiment of the rotation input unit according to the present invention.

As illustrated in the figure, the magnet portion 37 is composed of a plurality of magnets mounted on the outer circumference of the main input roller 20 (see FIG. 2), and the sensor portion 39 is close to the magnet portion 37. It consists of the first and second sensors 39a and 39b disposed so as to be arranged.

The magnet part 37 is an assembly of magnets in the form of a ring fitted to the outer circumference of the main input roller 20, more specifically, the body part 21 so that the N pole and the S pole are alternately arranged. The sensor part 39 is arranged as close to such a magnet part 37 as two sensors 37a and 37b for sensing the magnetic flux that changes during the rotation of the main input roller 20. As such sensors 37a and 37b, for example, a Hall sensor can be used.

The controller determines the rotation direction of the main input roller 20 based on the waveform of the magnetic flux change input from the first and second sensors 39a and 39b.

A method of determining the rotation direction of the main input roller 20 by the rotation input unit 30 according to the first and second embodiments of the present invention as described above will be described with reference to FIG. 5.

FIG. 5 is a diagram for describing a method of determining, by the controller, a rotation direction of the main input roller based on a waveform input to the contact part or the sensor part of FIG. 3 or 4.

As illustrated in the drawings, the positive contact 33b and the negative contact 33c of the contact portion 33 of the pattern sensing unit constituting the rotation input unit 30 according to the first and second embodiments of the present invention; The waveforms 35a and 35b input to the controller from the first and second sensors 39a and 39b of the sensor unit 39 have a constant phase difference. Specifically, the other waveform 35b forms a waveform that is 1/4 of the wavelength compared to one of the waveforms 35a.

Thus, classifying the high portion of waveforms 35a and 35b as 1 and the low portion to 0 yields a combination of 1s and 0s for waveforms 35a and 35b, as shown in this figure. For example, as shown in the figure, (1,0), (0,0), (0,1), (1,1), (1,0), (0,0), (0 Combinations of the types 1, 1 and 1 are possible.

At this time, when looking at the combination of (1,1) in the box, the waveform corresponding to the value of (1,0) appears in one direction (R), and in the other direction (L), (0, The waveform corresponding to the value of 1) appears. Accordingly, it is possible to determine which direction the main input roller 20 rotates in one direction (R) or the other direction (L).

Now, referring again to FIGS. 1 and 2, the press input unit 40 and the click feeling providing unit 50 will be described.

The push input unit 40 is interlocked with the pushing operation of the main input roller 20 to receive a specific signal.

The push input unit 40 according to the first embodiment of the present invention includes a circuit board 41, a switch 43, and an interlocking rod 45. The circuit board 41 is electrically connected to the control unit and is mounted on the side support part 11 forming the body 10. The switch 43 is formed on the circuit board 41. When the pressing force is applied, the switch 43 elastically deforms and contacts the spaced parts on the circuit board 41 so as to energize the parts to generate a signal on the circuit board 41. To be. Such a switch 43 may be, for example, a dome switch. The dome switch has an elastic force in itself. Furthermore, the interlocking rod 45 is a component for transmitting a force to which the main input roller 20 is pressed to the switch 43, and is rotatably mounted to the side support part 11 about the hinge shaft 45a.

Accordingly, when the user presses the main input roller 20, one end of the interlocking rod 45 is pressed to rotate the interlocking rod 45 about the hinge shaft 45a while the other end of the interlocking rod 45 is pressed. The switch 43 is pressed. As a result, a specific signal is generated as the switch 43 energizes the circuit board 41 to press the main input roller 20, and is input to the controller. Such a signal can be recognized, for example, as an acknowledgment signal upon pressing an enter key. Further, the pressed main input roller 20 is returned to its original state by the elastic force of the switch 43 itself.

The push input unit 40 according to the second embodiment of the present invention is composed of only the circuit board 41 and the switch 43. This will be described with reference to FIG. 6.

6 is a conceptual view illustrating a second embodiment of the push input unit according to the present invention.

As illustrated in the figure, the press input unit 40 is formed directly under the main input roller 20. The circuit board 41 is positioned on the base 15 forming the body 10 so as to lie below the main input roller 20, and the switch 43 is located directly below the main input roller 20. It is mounted on the circuit board 41.

Accordingly, in the push input unit 40 according to the second embodiment, unlike in the first embodiment, there is an advantage that it is not necessary to additionally include an interlocking rod 45.

Next, referring again to FIGS. 1 and 2, the click feeling providing unit 50 is formed between the end side of the main input roller 20 and the body 10, according to the rotation of the main input roller 20. It is a configuration to generate a feeling of click.

The click feeling providing unit 50 includes a movable cam 51, a fixed cam 53, and an elastic body 55.

The movable cam 51 is formed in a disc shape and fitted to the rotary shaft 23 of the main input roller 20 so as to be movable in the axial direction of the rotary shaft 23. The movable protrusion 51a protrudes on one surface of the movable cam 51, which may be formed at a 180 degree interval as shown. In addition, the movable cam 51 may have a coupling part 51b and may be fitted into a protrusion (not shown) protruding toward the movable cam 51 from the side support part 11 constituting the body 10. Accordingly, the movable cam 51 rotates together with the main input roller 20 while moving in the axial direction of the rotation shaft 23 by the projection of the rotation shaft 23 and the side support part 11 of the main input roller 20. You won't do it.

The fixed cam 53 is formed in a disc shape and is rotatably fitted to the rotation shaft 23 of the main input roller 20. Accordingly, the fixed cam 53 rotates together with the main input roller 20, but does not move in the axial direction thereof. In addition, one side of the fixed cam 53, that is, the surface facing the movable cam 51, the fixed projection 53a is formed to protrude continuously.

The elastic body 55 is formed between the main input roller 20 and the movable cam 51 to press the movable cam 51 toward the fixed cam 53. The elastic body 55 may be, for example, a compression coil spring and may be inserted into and supported in the body portion 21 while surrounding the rotation shaft 23 of the main input roller 20.

In the above description, the movable cam 51 is not rotated but the fixed cam 53 is rotated, but vice versa. In other words, the movable cam 51 is not fixed to the body 10 and is coupled to the main input roller 20 and rotates therewith, and the fixed cam 53 is coupled to the body 10 to be the main input roller ( 20) so as not to rotate together.

Thus, the movable cam 51 is movable in the axial direction of the main input roller 20 and does not rotate or rotate with it, and the fixed cam 53 does not rotate or rotate with the main input roller 20. Will not. Accordingly, when the elastic body 55 presses the movable cam 51 toward the stationary cam 53, the movable cam 51 moves through the fixed protrusion 53a while the movable cam 51 moves over the main input roller 20. As a result of clicking forward or repetitively in the axial direction of).

According to this configuration, when the main input roller 20 of the input device is rotated, the rotation input unit 30 is interlocked with the rotation of the main input roller 20 to receive the rotation direction thereof. When the main input roller 20 rotates, the click feeling providing unit 50 is operated to generate a click feeling. In addition, since the slipper 25 is formed on the outer circumference of the main input roller 20, no slip occurs when the main input roller 20 is rotated. In addition, when the main input roller 20 is pressed, the press input unit 40 works in conjunction with the main input roller 20 to receive a pressing operation of the main input roller 20.

The input device according to an aspect of the present invention may further include at least one sub input roller 60 in addition to the main input roller 20. This will be described with reference to FIG. 7.

At least one sub-input roller 60 may be provided at one side of the main input roller 20 or may be disposed to be distributed on both sides thereof. In this figure, the sub input roller 60 illustrates the 1st sub input roller 61 and the 2nd sub input roller 62 distribute | arranged on both sides of the main input roller 20, respectively.

The main input roller 20 and the at least one sub-input roller 60 are mounted on both side portions of the side support 11 of the body 10 so as to be supported. In addition, these input rollers 20 and 60 are arranged so that their central axis lies in the same plane.

The main input roller 20 is provided with the rotation input unit 30, the push input unit 40, and the click feeling providing unit 50 in the same manner as in the previous embodiment. These are shown in detail in FIG. 2 and are not duplicated in this drawing. In addition, the sub input roller 60 is provided with the same press input unit 40 as the press input unit 40 provided in the main input roller 20.

Furthermore, the serration portions 27 and 61a / 62a protrude from the outer circumference of the main input roller 20 and the sub input roller 60. These serge sections 27 and 61a / 62a are for facilitating cooperation between the chain section 70 and the input rollers 20 and 60 in the following embodiment (see FIG. 9, etc.), and the chain section ( 70 may not play a role similar to that of the anti-slip unit 25 described with reference to FIG. 2.

According to this structure, the rotation direction is input to the rotation input part 30 by its rotation through the main input roller 20, and the pressing operation | movement is input to the press input part 40 by its press. Further, the pressing operation of the sub input roller 60 is input to the push input unit 40 by the pressing thereof through the sub input roller 60.

Next, an input device according to another embodiment of the present invention will be described with reference to FIGS. 8 to 10 (and 7).

8 is a perspective view illustrating an input device according to another embodiment of the present invention.

As illustrated in the figure, the input device according to the present invention may further include a chain portion 70. As described above with reference to FIG. 7, the chain part 70 encloses a plurality of input rollers 20 and 60, namely, a main input roller 20 and a sub input roller 60 so as to interlock and rotate. To this end, the sub input roller 60 should be rotatably mounted to the body (10).

Accordingly, it is not necessary to rotate only the main input roller 20 for rotation input through the rotation input unit 30. In other words, the finger is placed on any part of the chain part 70 and the chain part 70 is pulled or pushed up.

In addition, despite the existence of such a chain portion 70, the main input roller 20 or the sub-input roller 60 is distinguished from each other, so that the pressing input is generated in the pressing input unit 40 interlocked with each other. Can be.

FIG. 9 is a cross-sectional view taken along the line VII-VII of FIG. 8.

As illustrated in FIG. 7 and FIG. 7, the support rods 13 are disposed between the respective input rollers 20 and 60, and the chain part 70 is formed of an assembly of a plurality of chain pieces 71 so as to have a main body. It is arranged to surround the input roller 20 and the sub input roller 60.

The serration parts 27 and 61a / 62a are formed in the outer periphery of the main input roller 20 and the sub input roller 60, respectively. These serrations 27 and 61a / 62a fit with the chain protrusion 71d of the chainpiece 71 constituting the chain portion 70. Accordingly, the force of moving the chain portion 70 causes the input rollers 20 and 60 to rotate strongly.

FIG. 10 is an enlarged perspective view for explaining the chainpiece of FIG. 9.

As illustrated in the figure, the chain piece 71 is formed to be spaced apart from the other end of the body (71a), the hook portion (71b) protruding hook shape from one end of the body (71a), and the body (71a) And a chain protrusion 71d protruding from the fastening rod 71c and the body 71a.

The chain piece 71 is formed of rubber, plastic injection molding, or the like, and it is preferable to provide a non-slip and constant touch.

According to this configuration, the main input roller 20 and the sub input roller 60 of the input device are integrally rotated by the chain portion 70. However, the rotation input is input only by the main input roller 20 and the rotation input unit 30. In addition, the main input roller 20 and the sub input roller 60 are each received a press input by the push input unit 40.

FIG. 13 is a perspective view illustrating a mobile communication terminal having an input device described with reference to FIG. 7.

In the embodiment illustrated in this figure, unlike the previous embodiment, the mobile communication terminal further includes a sub input roller 60 together with the main input roller 20 in the terminal body. Here, the configuration of the rotation input unit 30, the press input unit 40, and the click feeling providing unit 50 has been described with reference to FIG. 7 (see FIG. 2), and FIG. Since the description has been made through, descriptions thereof will be omitted.

The main input roller 20 and the sub input roller 60 are mounted to the outside of the slider unit 200 to the outside. The main input roller 20 is rotatably mounted to the slider unit 200, but the sub input roller 60 does not necessarily need to be rotatably mounted.

According to this configuration, the main input roller 20 scrolls the menu in the up and down direction on the drawing, the first sub input roller 61 scrolls the menu in the right direction on the drawing, and the second sub input roller 62 The menu scrolls to the left in the drawing. However, the main input roller 20 scrolls the menu by the rotation input unit 30 according to its rotation, but the sub input roller 60 scrolls the menu by the push input unit 40 according to its push input. The main input roller 20 scrolls by the push input unit 40 when the push input thereof is selected so that a specific menu activated is selected.

Accordingly, the menus A to D output in the longitudinal direction on the display 210 can be scrolled by rotating the main input roller 20, and the menus 1 to 4 output in the lateral direction are the sub input rollers. You can scroll by pressing (60). In addition, if you want to select a specific menu while scrolling, press the main input roller 20.

FIG. 14 is a perspective view illustrating a mobile communication terminal having an input device described with reference to FIGS. 8 to 10.

In the embodiment illustrated in the drawings, as in the previous embodiment, the detailed configuration of the rotation input unit 30, the press input unit 40 and the click feeling providing unit 50 and a description of how the input device is mounted on the terminal body will be described. Omit.

According to the present embodiment, the terminal body of the mobile communication terminal is equipped with a main input roller 20 and a sub input roller 60 (see FIG. 13 above), and a chain part 70 for wrapping and interlocking them. It is preferable that the input device is mounted on the slide part 200 so that the chain part 70 has the same height as the front surface of the upper cover 201.

Furthermore, the identification unit 80 is provided at a portion of the front cover 201 that is close to the chain 70. The identification part 80 is represented by →, an enter symbol, and ←, for example. Symbols (→ and ←) are symbols for identifying the scrolling function in the left and right directions on the drawing by pressing input of the first sub input roller 61 and the second sub input roller 62, respectively. It is a symbol for identifying the selection function by the push input of the main input roller 20. These symbols are intended to clarify which part the user presses for the push input as the main input roller 20 and the sub input rollers 61 and 62 are not exposed to the outside by the chain part 70. However, in the drawing, the vertically upward and downward scrolls are caused by the main input roller 20 rotating in conjunction with the sub-input rollers 61 and 62, even if any part of the chain portion 70 is pulled or pushed up in the longitudinal direction. As such, there is no need to specifically assign symbols for identification. In other words, the chain portion 70 itself is an identification factor for the longitudinal scrolling in the drawing.

According to this configuration, the method of scrolling and selecting a menu is the same as that of the embodiment described with reference to FIG. 13. However, as the sub input roller 60 is rotatably mounted on the terminal body, that is, the slider 200, the main input roller 20 and the sub input roller 60 are integrally formed by the chain part 70. It rotates in conjunction.

As the main input roller 20 and the sub input roller 60 are integrally rotated, unlike the previous embodiment, the main input roller 20 does not necessarily have to be selected and rotated for rotation input. In other words, when the finger touches and rotates at any point of the chain part 70, the main input roller 20 rotates together with the sub input roller 60, and the rotation direction of the main input roller 20 is rotated by the rotation input part ( This is because it is input to the controller through 30). In addition, unlike the rotational input to the main input roller 20, they are hidden by the chain part 70 at the time of pressing input to the main input roller 20 and the sub input rollers 61 and 62, respectively. Through the portion 80 it is possible to easily know the exact position for pressing them and to press accurately.

In the above described with reference to the accompanying drawings and the input device according to the present invention and a portable terminal having the same, the present invention is not limited by the embodiments and drawings disclosed herein, the scope of the technical spirit of the present invention Various modifications can be made by those skilled in the art. For example, the rotation input unit 30 is not necessarily composed of a combination of a conduction pattern-contact and a magnet-hall sensor, and a method using an optical sensor or the like is also possible.

13 and 14, the configuration in which the sub input rollers 61 and 62 are disposed above and below the main input roller 20, respectively, has been described. However, the sub input rollers 61 and 62 are the main input rollers. 20 is also possible to be arranged below or above adjacent. In addition, it is not necessary for each of the sub-input rollers 61 and 62 to generate an input for scrolling in the same direction as described in the scrolling of the menu unfolded in the lateral direction on the drawing. The scroll direction of each of the sub input rollers 61 and 62 may be appropriately determined in consideration of an arrangement relationship between the sub input rollers 61 and 62 and the main input roller 20 and the like.

Furthermore, the input device according to the present invention is not necessarily applied only to a mobile communication terminal. If the electronic device requires an input for scrolling and selecting a plurality of menus, the input device may be applied to a personal digital assistant (PDA) or an electronic dictionary.

As described above, the input device according to the present invention includes a main input roller rotatably supported by the body and a rotation input unit for receiving the rotation direction thereof, so that a new input method of the rotation method deviated from the pressing method can be realized. do. In addition, by rotating the main input roller, the amount of impact applied to the body is also reduced.

In addition, by providing a non-slip part and a click feeling part, it is possible to prevent a slip from occurring when the main input roller is rotated and at the same time obtain a feeling of click.

Further, the main input roller can also be pressed, so that the input by pressing auxiliary to the main rotational input is also possible.

In addition, when the sub input roller is adopted in addition to the main input roller, various types of input are possible. Also, by interlocking these input rollers through the chain portion, it becomes easier to rotate the main input roller.

The mobile communication terminal having the input device according to the present invention has the above input device and according to the rotational input thereof, and determines the movement of the cursor. You can easily scroll through multiple menus.

In addition, as a main input roller and a sub input roller, and all of them are configured to be pressed by the input method, it is possible to input the function of scrolling and selection between menus that are developed to cross in the longitudinal and transverse directions. It can be implemented as a device.

Furthermore, since the main input roller and the sub input rollers are interlocked by the chain part, there is no inconvenience in that the main input roller must be selected and rotated when the rotation is input. The identification can be made clear so that the push input through them can be made easily.
