BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for wirelessly manipulating an aircraft such as a vehicle, an airplane, a helicopter, and a ship,
Further, the present invention relates to a control device for another wirelessly operated body (a wireless camera for TV, a construction machine, an observation machine, etc.).

2. Description of the Related Art A radio control device includes a transmitter which is operated at hand, a receiver which receives a radio wave signal of the transmitter and outputs the radio wave signal as a current signal from a channel, and an electric signal which is individually supplied to each channel of the receiver. It consists of a servo, a receiver, and a power supply for the servo that are connected to each other, and these are built into the body of a vehicle, airplane, helicopter, ship, or the like. The receiver has a plurality of channels, and each channel is individually connected to each servo, and each servo operates according to a signal from each channel.

The transmitter has a plurality of channels incorporating an operating stick or operating wheel and a variable resistor,
The signal from each channel of the transmitter enters a predetermined channel of the receiver and activates the servo connected to that channel. That is, for example, a signal from channel 1 of the transmitter enters channel 1 of the receiver and moves the first servo, channel 2 of the transmitter enters channel 2 of the receiver and moves the second servo. .

[0004]

The conventional radio control device has several servos according to the number of operations (N) required for the airframe, channels of the receivers individually connected to the servos,
It requires as many transmitter channels as the number of receiver channels. Therefore, when adding another operation to the machine body, it is necessary to install a servo for the additional operation and add a number of channels corresponding to the additional servo to the receiver and the transmitter. Specifically, it is necessary to replace the receiver with a multi-channel receiver and the transmitter.

As described above, it has been expensive in the past to add another operation to the machine body, and it has not been easy. Therefore, the present invention does not change the number of channels,
In other words, the problem to be solved is to enable the addition of a servo to the transmitter and the receiver to enable the addition of an operation and solve the problem of the conventional technique.

[0006]

According to the present invention, in order to solve the above-mentioned problems, at least one main operation servo connected to one channel of a receiver is connected to another additional operation servo. Use a switchable means.

More specifically, the present invention relates to a transmitter having a steering channel and a throttle channel, a receiver for receiving a radio wave signal from each channel of the transmitter and converting it into a current signal, and an electric receiver. The steering servo and throttle servo, which are connected to each other and controlled by each channel signal from the transmitter, the power supply connected to the receiver and both servos, and the electric circuit between the receiver and the steering servo. (EN) Provided is a radio control device which has a connected switch and an additional servo electrically connected to a transmitter when the switch is switched, and operates the switch by a throttle servo.

Further, the present invention includes a transmitter having three or more channels and operating the channels at hand.
By converting the radio signal from the transmitter into a current signal and having the same number of channels as the number of channels of the transmitter that are individually linked with each channel of the transmitter, and the current signal from each channel of the receiver The same number of main operating servos as the number of operating receiver channels, a switch connected to an electric circuit between at least one channel of the receiver and at least one main operating servo, and an electric switch at a switching contact of the switch. Servo for additional operation connected to
Provided is a radio control device having a receiver and a power supply for each servo and operating the switch by one of the main operation servos.

[0009]

When one of the main operation servos on the machine body moves the switch and the contact of the switch is switched, the additional operation servo electrically connected to the switching contact moves the machine according to the signal in the channel of the receiver. Give to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which the present invention is applied to a radio control car (also called an RC car) is shown in FIG. 1, which will be described as one of the embodiments. The transmitter 1 includes a channel 1 having a steering stick and a channel 2 having a throttle stick. Signals from both channels are transmitted from an antenna 2 to a channel 1 and a channel 2 of a receiver 3 on an RC car as an airframe. And sent to.

The RC car has a first servo 4, a second servo 5 and a third servo 6. The channel 1 of the receiver 3 is connected to the first servo 4 via one contact 8 of the switch 7.
The steering angle is determined according to the steering signal from the channel 1 of the transmitter 1. The channel 2 of the receiver 3 is directly connected to the second servo 5 and determines the forward and backward movement of the RC car and its speed according to the throttle (speed) signal from the channel 2 of the receiver 1.

The other contact 9 of the switch 7 is connected to the third servo 6. The switch 7 is operated by the servo horn 10 of the second servo 5. That is, when the throttle stick is set to neutral and the RC car is stopped, the servo horn 10 of the second servo 5 actuates the switch 7 to connect the channel 1 of the receiver 3 to the third servo 6 and the transmitter. It becomes possible to control the third servo 6 by the channel 1 of 1.

The third servo 6 can adjust the vehicle height up and down, open and close the door, blink the lamp, operate the clutch, and the like. As a result, the switch 7 and the third servo 6 are turned to R
Other operations can be added to the steering and throttle operations simply by adding them to the C car.

The receiver 3 is connected to the power source 12 via the switch 11.
Connect to. When the RC car is not used, the switch 11 is open.

[0015]

[Effect] According to the present invention, it is possible to ensure the operation of more than the number of channels without touching the electronic circuit of the handset.
