BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmitter of a radio control device for remotely controlling a controlled object by radio waves, and more particularly to improving operability of a switch provided in the transmitter.

[0002]

2. Description of the Related Art Conventionally, a radio control device has been used to remotely control a controlled object such as a model airplane or model car by radio waves. The radio control device outputs a transmission radio wave according to the operation amount from the transmitter when the operator operates the stick lever or various switches of the transmitter, and the transmission radio wave is received by the receiver mounted on the controlled object. It receives and remote-controls the controlled vehicle based on the received signal.

3A and 3B show an example of a transmitter of a conventional radio control device, which is shown in FIG.
Is a plan view thereof, and FIG. 3 (b) is a side view thereof.

In the figure, reference numeral 1 is a transmitter, and two stick levers 2 and 3 are provided on the front surface thereof. The stick levers 2 and 3 can be operated up and down and left and right respectively, and the stick levers 2 and 3 can be automatically returned to the neutral position according to the purpose of operation. And this stick lever 2,
The radio wave is transmitted from the antenna 4 according to the operation amount of 3, and the controlled object is remotely controlled.

A trim switch 7 is composed of a pair of button switches 5 and 6, and has stick levers 2 and 3.
It is provided corresponding to the operating direction of. The trim switch 7 is for finely adjusting the operation amount (control amount) of the operated body with respect to the operation position of the stick levers 2 and 3 by operating the button switches 5 and 6.

More specifically, the trim switch 7 has two button switches 5 and 6 as shown in FIG. The button switches 5 and 6 are switches 5b and 6b attached to a base 8 such as a circuit board inside the transmitter.
The key tops 5b and 6b protruding outward from the transmitter case 1a are operated by one or two fingers.

For example, when the controlled object is a model airplane, the stick lever 2 has an automatic return function in the up / down and left / right directions, and can operate the elevator of the model airplane in the up / down direction and the aileron in the left / right direction. In addition, the stick lever 3 has an automatic return function only in the left-right direction,
You can control the engine throttle etc. in the vertical direction and operate the ladder in the horizontal direction.

At this time, in the case of a model airplane, the button switches 5 and 6 of the trim switch 7 are operated to make fine adjustments so that the model airplane can fly horizontally without operating the stick levers 2 and 3. .

[0009]

By the way, the fine adjustment by the trim switch 7 can be performed while confirming the movement of the controlled object if the controlled object is remotely controlled.
More accurate adjustment is possible. However, since the conventional trim switch 7 is operated by pressing the button switches 5 and 6, it is difficult to know which switch is being pressed when operated while looking at the controlled object, and there is a problem in that it is operated accidentally. there were.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a trim switch having good operability and less erroneous operation.

[0011]

In order to achieve the above-mentioned object, the structure of the present invention is a transmitter of a radio control device for remotely controlling a controlled object by radio waves, wherein the transmitter is arranged inside the transmitter. One of the switch main body that rotates about the rotation shaft and the pair of switch main bodies that are installed.
It is configured to have a switch including an operation unit that presses one of them.

[0012]

With the above structure, one switch can be used to operate two switch bodies.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.
FIG. 1 is an enlarged view of an essential part showing an example of a transmitter of a radio control device of the present invention. In the figure, 11 and 12 are switches
In the main body, the switch main bodies 11 and 12 are configured to have key stems 11a and 12a on their upper portions. The switch is operated by pressing the key stems 11a and 12a.

On the other hand, 13 is an operating portion, for example, a rotating shaft 15 supported by the case 10 or the base 14 of the transmitter.
It is rotatably supported by. In addition, the operation unit 13
Has an inverted T-shape about the rotating shaft 15 and has a pair of actuating portions 13a and 13b at positions corresponding to the stems 11a and 12a of the switch bodies 11 and 12, respectively. The operation section 13 and the switch bodies 11 and 12 constitute a trim switch, for example.

When the upper portion of the operating portion 13 is operated in the direction of arrow A, the operating portion 13 is operated in the right direction.
When the stem 11a is pressed by a, the switch main body 11 operates, and when it is operated to the left, the operating portion 13b presses the stem 12b and the key switch main body 12 operates.

Therefore, the operator can operate the operation section 13 with one finger such as a thumb and can select the switch body to be actuated according to the rotating direction of the operation section 13, so that the trim can be selected. When used as a switch, it has good operability and can be operated accurately.

[0017]

[Other Embodiments] FIG. 2 is a sectional view showing the main part of another embodiment of the present invention. The switch bodies 11 and 12 are attached to a base 14 such as a circuit board. As in the previous embodiment, the stems 11a and 12a are provided, and the switch bodies 11 and 12 are activated by pressing the stems 11a and 12a.

On the other hand, the transmitter case 20 has an opening 20a.
Is provided, and the operation portion 16 is provided so as to project from the opening 20a. More specifically, the operation unit 1
6 is held by the case 20 or the base 14 via a rotary shaft 15, and has actuating portions 16a, 16b at positions corresponding to the stems 11a, 12a. In addition, a curved concave portion 16c is provided on the upper portion of the operation portion 16.

Then, a finger is placed in the recess 16c, and the operating portion 16 is rotated in the direction of arrow B while sliding the finger. Then, the 16 actuating parts 16a and 16b press the stems 11a and 12a, respectively, and actuate the switch bodies 11 and 12 depending on the rotating direction.

As described above, in the embodiment shown in FIG.
As in the previous embodiment, it is possible to determine which of the switch bodies 11 and 12 is operating depending on the rotating direction of the operating portion 16,
When used as a trim switch, it can be operated accurately without erroneous operation.

In the above-mentioned two embodiments, the example in which the trim switch is applied is shown.
It can also be applied when two pushbutton switches are provided.

[0022]

As described above, according to the present invention, in the transmitter of the radio control device, the transmitter is provided with a pair of switch bodies disposed inside the transmitter and a rotary shaft about the rotary shaft.
The operation unit that presses either one of the switch bodies.
This is a configuration having a switch composed of and.

Therefore, even when the pilot is controlling the controlled object remotely, it is possible to confirm which switch main body is operating by operating the operating portion, and the operability is good and no malfunction occurs. Can be operated.
