The first protrusion 132 provided below the region of the body 131 subjected to the force is also lowered toward the substrate 100. At this time, the connecting portion 132c of the first protrusion 132 moves substantially horizontally to the center region of the body 131. This pushes the magnet part 110 to the center area of the body 131. Thereafter, when the force is removed, the body 131 is restored to its original position by the second elastic member 134 provided outside the first protrusion 132. At this time, the first protrusion 132 pushing the magnet 110 is also restored.

As a result, when the user presses the center region of the body 131, the dome switch 160 is pressed by the second protrusion 133. In this case, a separate elastic member may be provided in an adjacent region of the second protrusion 133.

In addition, a cover unit 140 is provided outside the operation unit 130 to improve a user's contact feeling.

It is preferable to provide. In the present exemplary embodiment, the first to fourth magnetic sensors 151, 152, 153, and 154 may be arranged to be symmetrical with each other in the center point region of the circular magnet. That is, as shown in FIGS. 1 and 5, it is effective to dispose the first to fourth magnetic sensors 151, 152, 153, and 154 at the center point of the circular magnet. This reduces the overall size of the pointing device and improves the sensitivity of the magnetic sensor. In addition, the present invention is not limited thereto, and as illustrated in FIG. 6, the first to fourth magnetic sensors 151, 152, 153, and 154 may be arranged to be spaced apart from each other at the center point of the circular magnet.

The sliding guide unit 170 is provided on the substrate 100 and includes a predetermined inclined surface. That is, it is effective that the sliding guide 170 has a triangular shape in cross section as shown in FIGS. 3 to 6. When the inclined portion 132b of the first protrusion 132 descends or rises, the inclined portion 132b is connected to the inclined surface of the sliding guide portion and descends and rises. As a result, when the first protrusion 132 is lowered, the first protrusion 132 is lowered along the inclined surface, whereby the vertical portion 132a of the first protrusion 132 moves downward, and the inclined portion ( 132b is inclined, and the connecting portion 132c is in horizontal motion. As such, the first protrusion 132 may be supported by the sliding induction unit 170 to support the vertical movement of the first refraction unit 132 to be changed into a horizontal movement.

In addition, as illustrated in FIGS. 3 to 6, a predetermined pad 180 may be formed on the substrate 100 to which the second elastic member 134 is connected. Damage to the substrate 100 due to the second elastic member 134 may be prevented through the pad 180. In addition, when excessive force is applied to the edges of the manipulation unit 130 or the cover unit 140, they may be connected to the substrate 100 to damage the substrate 100. However, as in the present modification, the pad 180 may be provided on the substrate 100 to prevent damage to the substrate 100 due to the operation unit 130 and the cover unit 140.

3, 4, and 6, the controller 155 is provided at the center of the substrate 100, and the first to fourth magnetic sensors 151, 152, and 153 are disposed around the controller 155. , 154 may be arranged at regular intervals. In this case, as shown in FIG. 3, the first to fourth magnetic sensors 151, 152, 153, and 154 and the control unit may be mounted on a substrate. As shown in FIGS. 4 and 6, the control unit 155 and the first to fourth magnetic fields may be installed. The sensors 151, 152, 153, and 154 may be packaged in a single package and disposed in the central area under the substrate 100.

In addition, as shown in FIG. 4, a fixing magnet 135 may be provided in the end region of the second protrusion 133 of the manipulation unit 130. Through the fixing magnet 135, the detection capability of the magnetic field change of the sensor unit 150 may be improved.

As shown in the drawing, first to fourth magnetic sensors 151, 152, 153, and 154 are provided in the body 121 of the fixing part 120. The first to fourth magnetic sensors 151, 152, 153, and 154 may be disposed on the same plane as the magnet part 110. In this case, the controller 155 of the sensor unit 150 may also be disposed in an upper region of the substrate 100.

In addition, as illustrated in FIG. 6, the body 131 of the operation unit 130 may be a first body 131a having a first protrusion 132 and a second body 131b having a second protrusion 133. It may be separated. The first body 131a may be pressed to lower the first protrusion 132 to move the magnet part 110 in the horizontal direction. In addition, the dome switch 160 may be turned on / off by pressing the second body 131b to lower the second protrusion 133. In this way, the movement of the first protrusion 132 and the second protrusion 133 may be separated by separating the first body 131a and the second body 131b.

In addition, in the present exemplary embodiment, since the magnet 110 moves horizontally between the substrate 100 and the fixing part 120, friction between the substrate 100 and the protrusion plate 121 of the fixing part 120 is performed. This can happen. Therefore, in order to reduce such friction, it is preferable to include a material capable of reducing friction in an area between the substrate 100 and the magnet part 110 and an area between the protrusion plate 121 and the magnet part 110. In the present exemplary embodiment, a material having a small frictional force with respect to the magnet part 110 may be disposed on the substrate 100.

Hereinafter, the operation of the pointing device of the present embodiment having the above-described structure will be described.

The magnet part 110 inside the pointing device is normally positioned at an initial position set by the fixing part 120 of the present embodiment. The magnet part 110 is blocked from the movement in the vertical direction (Z axis direction) by the protrusion plate 122 of the fixing part (120). In addition, the magnet part 110 has a horizontal direction (X-axis and Y-axis direction) by the body portion 121 and the first elastic member 125 of the fixing portion 120 in the state where no external force (pressure) is applied. Movement is fixed. The initially set position refers to the position of the magnet part 110 in which the center of the circular magnet part 110 and the center of the body part 121 overlap each other. At this time, the circular magnet portion 110 is spaced apart from the outer wall surface of the body portion 121 in the fixing portion 120 by the same interval. In the present embodiment, the output of the first to fourth magnetic sensors 151, 152, 153, and 154 when the magnet part 110 is in the initial position is set as a reference point.

As described above, when a force is not applied to the operation unit 130 of the pointing device, the output of the sensor unit 150 outputs a reference point (0,0). As a result, the position of the pointer on the screen does not change.

Down toward the substrate 100. That is, the body 131 of the operation unit 130 is lowered in the direction of the substrate 100. As a result, the second elastic member 134 of the pressing region is compressed, and the first protrusion 132 is also lowered in the direction of the substrate 100 like the body 131. At this time, the connecting portion 132c of the first protrusion 132 performs a horizontal motion, and the force of the horizontal motion is applied to the magnet part 110 so that the magnet part 110 of the pressing area is the center of the fixing part 120. Will be moved to. That is, when pressing the left side of the cover portion 140 as shown in (a) of Figure 7 the magnet portion 110 is moved in the right direction as shown in FIG. Due to the movement of the magnet unit 110, the magnetic field applied to the first to fourth magnetic sensors 151, 152, 153, and 154 is changed. In this embodiment, not only the separation of the magnet unit 110 through the fixing unit 120 but also prevents the movement of the magnet unit 110 in the vertical direction (Z-axis direction) relative to the upper surface of the substrate 100. , Move only in the horizontal direction (X-axis and Y-axis direction). As a result, the magnetic field of the magnet unit 110 may also be changed in the horizontal direction with respect to the surface of the substrate 100. Therefore, the sensing capability of the first to fourth magnetic sensors 151, 152, 153, and 154 of the sensor unit 150 provided under the substrate 100 may be improved.

For example, when the magnetic field center of the circular magnet is located at the center point of the magnet unit 110, as shown in the solid line of FIG. 8, when the magnet unit 110 is not moved, the center of the magnetic field is the first to fourth magnetic sensors ( 151, 152, 153, and 154 in the central region, i.e., the center point of the horizontal plane (see O in FIG. The first to fourth magnetic sensors 151, 152, 153, and 154 output the initially set voltage. However, when the magnet part 110 moves in the X-axis direction as shown in the dotted line of FIG. 8, the magnetic field center of the magnet moves in the X-axis direction (A ′ in FIG. 8). As a result, the first to fourth magnetic sensors 151, 152, 153, and 154 output different voltages to the change of the magnetic field instead of the initially set voltage. This allows the system to detect this change in voltage and move the on-screen cursor in the X-axis direction.

That is, the system can compare the output of the two magnetic sensors provided on the X-axis and Y-axis lines, respectively, and display the change amount of the pointer. This is described as follows. If there is no movement at the initial position of the magnet unit 110, since the first to fourth magnetic sensors 151, 152, 153 and 154 are located at the center of the magnetic field, all output the same output voltage. At this time, the difference between the output of the first magnetic sensor 151 and the output of the second magnetic sensor 152 becomes zero, and the amount of change in the X-axis direction becomes zero. In addition, it can be seen that the difference between the output of the third magnetic sensor 153 and the output of the fourth magnetic sensor 154 is also zero, and the amount of change in the Y-axis direction is also zero. However, as shown in FIG. 7, when the magnet unit 110 moves in the X-axis direction, the output of the first magnetic sensor 151 decreases or increases, and the output of the second magnetic sensor 152 is the first magnetic sensor 151. In contrast, it increases or decreases. In contrast, the third and fourth magnetic sensors 153 and 154 increase or decrease in the same manner. Accordingly, the difference between the output of the first magnetic sensor 151 and the output of the second magnetic sensor 152 is not zero, and has a positive value or a negative value. The difference between the outputs of the four magnetic sensors 154 is zero. In this embodiment, it has a positive value and moves a point on the screen in the positive X-axis direction. Of course, in the above description, the above-described calculation is described in the system, but in the present embodiment, the above-described calculation may be performed in the sensor unit 140.

In addition, when the sliding guide part 170 supporting the movement of the first protrusion 132 is provided on the substrate 100 as in the modification of the present embodiment, due to the lowering of the body 131 of the operation part 130.

That is, when the user moves the magnet unit in the horizontal direction by operating the operation unit of the pointing device 1000, the sensor unit senses the X coordinate and the Y coordinate according to the movement of the magnet unit, and the signal corresponding to the X coordinate value and the Y coordinate value. Is output to the control unit 1500. Here, the sensor unit may include a magnetic sensor whose output value is changed according to the magnetic field of the magnet, and the magnetic sensor may be symmetrically disposed on the X axis and the Y axis to sense the X and Y axis movements of the magnet part. The controller 1500 moves the pointer or cursor in the screen display unit 1300 using the X coordinate value and the Y coordinate value. That is, the controller 1500 calculates the vector using the X coordinate value and the Y coordinate value applied from the pointing device 1000. Then, the pointer or cursor in the screen display unit 1300 is moved as much as the vector. That is, it is preferable to move the pointer as much as the input vector by using the coordinates of the screen on which the pointer is located on the current screen as a reference point. The pointer or cursor is preferably moved in the vector direction. At this time, the pointer or the cursor is not limited to the vector size, but preferably moves at the same speed. Of course, this can increase with the duration of the vector. That is, when the same vector is continuously input, the moving speed of the pointer or the kernel can be increased.

As described above, the present invention can fix the magnet in the vertical direction and move the magnet in two directions to move the magnet in the horizontal direction.

In addition, the present invention can improve the magnetic field sensing capability of the magnetic sensor by moving the magnet two-dimensionally in the horizontal direction.

In addition, the present invention can compact the magnetic sensor in the region inside the magnet to reduce the size of the entire device.

The present invention is not limited to the above-described embodiments, but may be implemented in various forms. That is, the above embodiments are provided to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the present invention, and the scope of the present invention should be understood by the claims of the present application. .
