At this time, the hooks 610 are more preferably formed at four corners of the coupling bracket 600, respectively.

In particular, a plurality of separation preventing projections 620 are formed on the surface of the coupling bracket 600 to prevent the separation of the pressing unit 400, the respective separation preventing projections 620 in the pressing unit 400 Coupling hole 420 is inserted is coupled.

Hereinafter, an example of a manipulation operation using the manipulation apparatus having the above-described series of structures will be described with reference to FIGS. 4A and 4B.

First, if a user wants to change the position of a pointer to a corresponding menu for activation of another specific menu on a display screen on which one of the plurality of menus is activated, the dial unit 100 of the operating device is rotated to change the position of the pointer. Move the position in a specific direction quickly.

In this case, the main PC 200 is a rotational direction and the displacement amount of the dial portion 100 through a pair of reflectors 210 and 220 for emitting and receiving light to the uneven portion 120 formed on the bottom surface of the dial portion 100. Will be confirmed.

At this time, the confirmation of the rotation direction of the dial unit 100 is performed by checking when the phase difference of the signal sensed by each of the reflectors 210 and 220 is changed.

That is, the dial unit 100 checks the time difference reached from the time point of change of the phase identified by one reflector 210 to the same phase in the same direction identified by the other reflector 220. It can be seen whether it is rotated clockwise or counterclockwise.

In addition, the displacement amount is identified based on the number of times that the corresponding phase value is reached from the first phase value checked by each of the reflectors 210 and 220.

Of course, the displacement amount may be confirmed based on the number of variations of the phase value, or may be confirmed by other methods.

Then, when the rotation direction and the displacement amount of the dial unit 100 using the pair of reflectors 210 and 220 are completed, the checked information is transmitted through the signal connection terminal 260 of the main PC 200. It is provided as a device to which the operation device is applied.

Accordingly, the position of the pointer according to the control of the main PC 200 based on the information or the control unit (not shown) of the product provided with the operation device is displaced according to the rotation amount of the dial part 100. Change and display.

When the pointer is located at the desired point as described above, the operation is completed by pressing the button unit 300 to turn on the contact of the enter switch 250 so as to execute the corresponding command.

Of course, as described above, the displacement movement of the pointer may not be performed only by the rotation of the dial part 100, and the pointer is moved through a series of processes for pressing the dial part 100 in the direction of movement of the pointer. The movement of can be made.

That is, in the initial state as shown in FIG. 4A, to press the circumferential portion in the direction desired to be moved among the portions of the dial portion 100 to move the pointer in any one side direction, the dial portion 100 ) Presses the supporter unit 500 of the corresponding part while being inclined toward the pressed part side, and thus the main PC 200 fixed to the supporter part 500 and the supporter part 500 is also the dial. The inclination direction of the part 100 is inclined in the same direction.

Its state is as shown in Figure 4b.

Therefore, of the contact switches 230 provided on the bottom of the main PC 200, the respective contacts 231 and 232 of the contact switches 230 provided on the inclined direction side of the main PC 200 are located at the bottom thereof. By being energized with each other by the dome 241 which is pressed while being in contact with the pressing protrusion 410 of the pressing unit 400, selection is made according to the movement in the corresponding direction.

As a result, the pointer is displayed while being moved in the corresponding direction.

If the pressing force provided through the dial part 100 is released in the above-described state, the dome 241 constituting the dome sheet 240 is restored to its original form by its restoring force, and thus the corresponding contact switch 230 Each of the contacts 231 and 232 is shorted to each other.

The above-mentioned movement of the pointer by pressing the dial part 100 is preferably used when it is desired to move step by step, and the movement of the pointer through the rotation of the dial part 100 may be performed by a simple operation. It is preferable to use it when movement is required.

Of course, after the rough movement of the pointer is performed through the rotation of the dial part 100, the pointer may be manipulated so as to finely move the pointer by pressing the circumference of the dial part 100.

As a result, even if the user does not press the button for directional movement by the above-described series of steps, the pointer position in the corresponding direction is smoothly and quickly changed, thereby improving the operation efficiency.
