Figure 4 is a schematic internal and external structural diagram of the integrated control switch 3 according to an embodiment of the present invention, Figure 4 (a) to (c) for the operation state of the integrated control switch A cross-sectional view taken along line A-A' of FIG. 4D is shown, and a cross-sectional view taken along line B-B' of FIG. 4D is shown in FIG. 4E. Figure 4 (a), (e), (f) shows the state in which the external force is removed from the integrated button 4, and in (b) and (c), the push operation and the seesaw operation occur respectively by applying an external force to the integrated button. The state is shown, and (f) shows the appearance of (a) viewed from the front.

Referring to Figure 4 (a), (b), (c), in one embodiment of the integrated control switch of the present invention, the lower surface of the integrated button body 41 has a seesaw movement pressing part 45 and a push movement The pressing portion 46 is formed, and is disposed at positions corresponding to the push switch 6 and the seesaw switch 5, respectively. The push switch and the seesaw switch each perform a switching function by a push operation and a seesaw operation of the integrated button 4, and when the push operation and the seesaw operation occur, a push motion pressing unit 46 formed on the integrated button and The seesaw motion pressing unit 45 is applied to the push switch 6 and the seesaw switch 5 through vertical motion (see Fig. 4(b)) and seesaw motion (or rotary motion, see Fig. 4(c)), respectively. Switching action occurs by transferring force. The push movement pressing unit or the seesaw movement pressing unit may directly contact a push switch or a seesaw switch to transmit the force, or may indirectly transmit the force through various means including a spring, a plunger, and a rubber. The push movement pressing unit or the seesaw movement pressing unit need not necessarily be formed on the integrated button, but may be formed on a separate movement transmission block (not shown) coupled with the integrated button.

The seesaw switch 5 and the push switch 6 may be implemented as a tact switch or a rubber dome switch, and are not limited thereto, and any switch that returns to its original position by an elastic force when an external force is removed. Can be implemented as In addition, it is preferable that the seesaw switch has a longer traveling stroke and less operating force or less elastic force than the push switch. On the other hand, even when the external force is removed from the integrated button as shown in (a) and (f) of Fig. 4, since one side of the lower part of the integrated button body 41 is located in close contact with the seesaw switch buttons 51 on both sides, the integrated button Returns to its original position and serves as a guide for vertical movement during a push operation.

The integrated control switch 3 according to the present invention may further include a guide structure for guiding the push operation and the seesaw operation in the integrated button 4. That is, circuit wiring or electrical and electronic elements in electrical communication with the push switch and the seesaw switch are arranged on one side of the printed circuit board 9 firmly installed inside the housing, and the integrated button holder 7 and the push switch ( 6) and a seesaw switch 5 can be installed. As shown in (e) of FIG. 4, one side of the lower part of the integrated button body 41 is arranged so as to be in close contact with one side of the interior of the integrated button holder part 7, and the cylindrical hinge shaft 47 is The integrated button 4 is prevented from being separated from the integrated button holder part 7 by penetrating one side of the integrated button and being inserted into the hinge axis corresponding hole 77 formed in the integrated button holder part 7. Guide to stable seesaw movement (or rotational movement) and push movement (or vertical movement).

Inside the integrated button holder part, a push switch 6 is installed under the push movement pressing part so that a switching operation occurs by receiving the force of the push movement pressing part 46 when the integrated button is pushed. In this embodiment, the integrated button holder part is applied to guide the push operation and the seesaw operation of the integrated button 4, but the present invention is not limited thereto and other modifications are possible. For example, a separate exercise transmission block (not shown) combined with an integrated button is provided, and a vertical guide part for a push operation and a hinge axis for a seesaw operation are formed in the exercise transmission block to enable the push operation of the integrated button. You can also take the structure of guiding and performing seesaw movements.

When the integrated button is pushed, the lower end of the integrated button body 41 and the push motion pressing part 46 are vertically inserted and guided downward along the vertical guide part 71 formed in the integrated button holder part. ) Is operated (see Fig. 4(b)). When the integrated button is being pushed, the lower end of the seesaw motion pressing part 45 or the integrated button body 41 is fitted into the vertical guide part 71, thereby inhibiting the rotation of the integrated button, and thereby the seesaw switch 5 ) Operation is prevented. On the other hand, when the push external force applied to the integrated button is removed, the integrated button 4 receives the elastic force of the push elastic member 8 and moves upward and the integrated button returns to its original position (see Fig. 4(a)). In the state, the height of the push motion pressing part 46 is preferably near the boundary line where the upper end of the vertical guide part 71 and the lower end of the seesaw motion limiting jaw 72 meet.

When the seesaw motion occurs due to the external force of the seesaw in the state where the integrated button is returned to its original position, the push motion pressurizing unit 46 slides along the slope of the seesaw motion limiting jaw 72, and the seesaw motion pressurizing unit 45 switches 5) to generate a switching operation (see Fig. 4 (c)). When the integrated button is in the seesaw operation, the push movement pressing unit 46 is in contact with the seesaw movement limiting jaw 72, so that the push operation of the integrated button is prohibited, thereby preventing the push switch 6 from being operated. That is, the vertical guide part 71 and the seesaw motion limiting jaw formed on the integrated button holder part 7 allow the push operation of the integrated button and the seesaw operation to be performed separately, so that the operation of the integrated control switch is alternatively made clearly. Is configured to On the other hand, when the external force applied to the integrated button is removed, the seesaw motion pressing unit 45 receives the elastic force of the seesaw switch 5 and the integrated button returns to its original position.

5 is a schematic internal and external structural diagram of the operating state of the integrated control switch according to an embodiment of the present invention. Of these, Fig. 5(a) shows a state in which both the push switch 6 and the seesaw switch 5 are turned off in a normal state in which no external force is applied, and Fig. 5(b) shows the push for vertical movement. The external force is applied to the integrated button 4 and only the push switch is turned on. FIG. 5(c) shows the seesaw with the external force applied to the integrated button and only the seesaw switch is ON. This indicates the state of being.

5A and 5B, the shape of the hinge axis corresponding hole 77 permits the rotational movement and vertical movement of the integrated button 4 while minimizing the horizontal movement of the integrated button. It is preferable that the lower and upper portions of the corresponding hole 77 are formed in a round shape, the side surface is vertical, and the width 73 of the hinge shaft corresponding hole is about the size of the diameter of the hinge shaft 47. In addition, the minimum and maximum positions of the integrated button in the vertical direction can be configured to be limited by the height of the hinge axis corresponding hole 74.

As shown in Figure 5 (a), in the case where the external force is removed from the integrated button, the integrated button 4 is located in close contact with the lower side of the integrated button body 41 from the seesaw switch buttons 51 on both sides. It returns to its original position and allows the seesaw motion pressing part 45 to pass without being caught on the vertical guide part 7 during the push operation.

On the other hand, due to the elastic force provided by the push spring 8 installed in the integrated button holder part 7, the integrated button 4 is located at the maximum height from one surface of the housing (or printed circuit board), but the integrated button 4 The hinge shaft 47 inserted in the hinge shaft 47 is blocked at the upper end of the hinge shaft corresponding hole 77, and the maximum height of the integrated button may be limited.

In addition, since the height of the push motion pressing part 46 in the normal state without external force on the integrated button is located near the boundary line where the upper end of the vertical guide part 71 and the lower end of the seesaw motion limiting jaw 72 meet, the integrated button seesaw operation When this occurs, the push motion pressing part 46 slides along the slope of the seesaw motion limiting jaw 72 to rotate the integrated button 4.

And, as shown in (b) of Figure 5, when the push operation occurs on the integrated button in a normal state without external force on the integrated button, the side of the hinge shaft 47 formed in the integrated button 4 is a hinge axis corresponding hole ( 77), so that the lower end of the integrated button body 41 and the push motion pressing part 46 have almost no horizontal movement and the side and the vertical guide part of the hinge shaft corresponding hole 77 ( It is guided directly downward along 71) and turns on the push switch 6. When the integrated button is being pushed, the lower end of the integrated button body 41 is fitted into the vertical guide portion 71 to prevent the rotation of the integrated button, thereby preventing the operation of the seesaw switch 5.

On the other hand, the minimum height of the integrated button may be limited by forming the hinge shaft 47 to be blocked at the lower end of the hinge shaft corresponding hole 77. Then, when the external force is removed, the integrated button is returned to its original position by the elastic force of the push elastic member 8 and the push switch 6, and the push switch is turned off.

When a seesaw operation occurs on the integrated button in a normal state without external force on the integrated button, the push movement pressing unit 46 rotates upward along the slope of the seesaw movement limiting jaw 72 so that the push movement pressing unit contacts the push switch. This is forbidden.

In addition, when the seesaw operation of the integrated button is completed, the seesaw movement pressing unit 45 operates the seesaw switch 5 to turn the seesaw switch ON. In addition, since the push motion pressing part 46 is in contact with the seesaw motion limiting jaw 72, the push operation of the integrated button is prohibited, and the operation of the push switch 6 is prevented. On the other hand, when the external force is removed, the integrated button is returned to its original position by the elastic force of the seesaw switch 5 and the seesaw switch is turned off.

The integrated control switch according to the present invention can perform both a push operation and a seesaw operation from one integrated button 4, and controls the on/off (ON/OFF) of the laser light output by the push operation, and The switching signal generated by the operation may wirelessly up/down (UP/DOWN) a page of the presentation screen through the wireless transmitter 10. When an external force in the vertical downward direction is applied to the integrated button 4 and a push operation occurs, the push switch 6 is turned on to output a laser light, and when the external force is removed, the integrated button returns to its original position by an elastic force. The push switch is turned off and the laser light output is turned off.

And when the seesaw action occurs due to the application of an external force on the integrated button, the seesaw switch 5 operates and the presentation screen page is UP or DOWN. When the external force is removed, the integrated button returns to its original position by the elastic force. The page up/down function is blocked.

On the other hand, the integrated control switch of the present invention is configured so that the push operation of the integrated button and the seesaw operation are performed selectively, so that the page of the presentation screen by the seesaw operation in the state where the laser light output by the push operation is ON. The up/down control function may be prevented, or the laser light output may be prevented from turning on while the presentation screen is being paged up/down controlled.

Therefore, due to the integrated control switch according to the present invention, at the time of presentation, the presenter moves and presses a number of buttons to turn on/off the laser light output and up/down the page of the presentation screen. As the laser light output and page up/down operations on the screen can be performed conveniently and safely, the presenter can focus on the presentation with confidence.

As described above, the page up/down control function of the presentation screen of the wireless presenter according to the present invention has been described in an embodiment in which a seesaw operation is used, but the page up/down control function is a sliding operation instead of a seesaw operation. In this case, the integrated control switch of the wireless presenter may be a sliding switch instead of a seesaw switch.
