Abstract

PURPOSE:To attain a high control efficiency by arranging trims, which adjust the quantity of correction of a trim correcting means, within reach of four fingers other than the thumb in a transmitter body. CONSTITUTION:Trims 7 and 8 are used to finely control the advance speed and the advance direction of a radio control car, and the left trim 7 is provided with a pair of up and down switches 7a and 7b, and the right trim 8 is provided with a pair of up and down switches 8a and 8b, and they are arranged at an angle on a transmitter body 1. The counter value of an up/down counter is varied by operation of trims 7 and 8 to set the quantity of correction, and the controlled variable controlled by sticks 2 and 3 is corrected. Since the quantity of correction is continuously increased or reduced by continuous depression of one of these switches and switches can be momently operated, the advance speed, the advance direction, etc., of a body to be controlled are finely adjusted. It is possible that an operator operates trims 7 and 8 with fingers other than thumbs while operating sticks 2 and 3 with thumbs, and a high control technique for the body to be controlled is realized.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a radio-controlled transmitter that sends a control signal to a controlled object such as a radio-controlled car.

<Prior art and its drawbacks> A radio-controlled transmitter that wirelessly controls a controlled object such as a radio-controlled car or a radio-controlled airplane has a stick that adjusts the speed and direction of travel, and a trim that finely adjusts the control amount by operating the stick. It is common practice to arrange pairs of transmitters on the left and right sides of the transmitter body. For example, in the case of a radio-controlled car,
The speed control stick is placed on the left side, while the direction control stick is placed on the right side, and by moving the left stick up and down with the left thumb, you can increase or decrease the rotation speed of the radio-controlled car's servo motor or engine. By moving the right steering wheel left and right with the thumb of the right hand, the direction of the steering wheel is changed and the direction of travel is changed. In addition, ratchet-type trims are placed near the left stick and near the right stick. For example, when the stick is in neutral, you can slide the left trim up and down with your left thumb to adjust the speed and direction. Moving and speed? h 3JE] and slide the right trim left and right with the thumb of the right hand to strangely change the direction of travel and improve the piloting technique.

However, this type of ratchet type trim adjusts the speed and direction by increasing or decreasing the resistance value of the variable resistor for each pitch, so the correction amount is adjusted in stages, and the variable range is limited to 1 pitch. There was a problem in that the adjustment range was restricted to the sliding width, making it difficult to operate smoothly. Also, when making this trim, you usually have to take your thumb off the stick and only operate the trim. It was difficult to make full use of sophisticated maneuvering techniques in vehicles that required delicate speed adjustments and steering operations.

<Object of the Invention> The present invention has been made in view of the above circumstances, and includes an up-dow/collar foot section as an l-rim correction means, and transmits a trim for adjusting the correction amount of the trim correction means. By placing it within reach of the other four fingers other than the thumb on the main body of the aircraft, you can fine-tune the advancing speed of the piloted object, etc., and also operate the trim with the other fingers while operating the stencil with the thumb. The purpose of the present invention is to provide a radio-controlled transmitter that can realize advanced maneuverability.

<Structure and Effects of the Invention> The present invention includes a stick for controlling the traveling speed of a steered object, etc., and a trim for correcting the control amount based on the operation of the stick, and provides a control signal to the steered object. In the radio-controlled transmitter, the trim is composed of an Asops inch and down switch, and a trim correction means including an amplifier down counter section that sets a correction amount based on the operation of each switch is connected to the control means of the stick. The present invention is characterized in that the trim of the trim correction means is disposed on the transmitter main body within reach of all four fingers except the thumb.

When the radio-controlled transmitter of this invention is configured as described above,
Equipped with Asops inch and down switch notches as trims for setting the correction ■, the amount of correction can be increased or decreased continuously by holding down either switch, and can also be operated instantaneously. It is possible to make fine adjustments to the speed and direction of the control object.In addition, the trim, which includes a pair of anopus inch and down switches, is placed within the reach of all four fingers except the thumb on the transmitter body. Because of this arrangement, it is possible to operate the trim with other fingers without operating the stick with the thumb.Therefore, the stick and trim can be operated at the same time, making it possible to realize advanced maneuvering techniques for the controlled object.And Since this trim can reduce the amount of correction when one button is pressed, especially when the object to be operated is a radio-controlled car, the i-rim adjustment will be highly accurate, and it will be useful for engine cars that are limited to electric cars.
3, driving performance improves dramatically. Furthermore, since the variable range of the direction of movement can be finely adjusted for controlled objects such as radio-controlled airplanes and radio-controlled motorboats, advanced control techniques can be used.

<Example> An example in which the radio-controlled transmitter of the present invention is applied to a radio-controlled car will be described below based on the drawings.

FIG. 1 is a front view of a radio-controlled transmitter according to an embodiment of the invention.

The radio-controlled transmitter has a substantially rectangular shape with a stick 2.3 and auxiliary trims 4, 5 arranged on the left and right sides of a transmitter main body 1, and a power switch in the center. Further, trims 7.8 are arranged on the left and right sides of the upper surface, and an antenna 9 is also provided. Further, the transmitter main body 1 includes a trim correction means 10, a control means 14, a transmission circuit (not shown), etc., and is capable of transmitting a control signal to a radio-controlled car, which is a controlled object.

The sticks 2 and 3 are operating sticks that control the speed and direction of movement of the radio-controlled car, and the left stick 2 is for speed control and can be moved up and down. Raising it increases the rotation speed of the radio-controlled car's servo motor, speeding it up. - way,
If you lower the left stick 2, you can move backwards and stop at the neutral position. Also, right stay 7
The stick 3 is for direction control and can be moved left and right.If you move this right stick 3 left and right with your right thumb, the steering wheel of the radio-controlled car will turn left and right, allowing you to change the direction of movement of the radio-controlled car. ing.

The auxiliary trims 4 and 5 are of the ratchet type, and the trim volume 4a, which will be described later, is adjusted by sliding the thumb every l pitch.
The controller corrects the control meter by changing the resistance of the controller 5a, and is placed near the left and right sticks 2 and 3, respectively.

In this example, since the trims 7.8 are provided, the auxiliary trims 4 and 5 can be omitted.

Trim 7.8 changes the speed and direction of the radio controlled car to iXk 3F! It is a joint, and the left and right trim 7
．． Each of 8 is provided with a set of up switches 7a, 8a and down switches 7b, 8b, which are arranged diagonally on the upper surface of the transmitter main body 1. The speed of the radio-controlled car increases slightly when pressed with the big or middle finger, while the speed can be decreased slightly when the down switch 7b is pressed.Also, the up switch 8a of the right trim 8 is pressed with the right index finger. Alternatively, when pressed with the middle finger, the steering wheel of the radio-controlled car moves slightly to the left, while when the down switch 8b is pressed, the steering wheel moves slightly to the right.

An amplifier 13 is connected. The output side of this OP amplifier 13 is connected to the mixing section 14a of the control means 14 via a resistor R3, and the counter value is varied by the trim 7.8Q operation to set the correction (2). The configuration is such that the control 4111 amount controlled by 3 can be corrected.

The control<if means 14 is equipped with a mixing section 14a, an encoder 1c14b, etc., and outputs a control meter or a correction amount to the next-stage transmitting circuit in response to the operation of the stick 2.3 and trim 7.8. be. Mixing section 14
Stick volume controllers 7c and 3c, which are variable resistors whose negative end is connected to the DC power source B and whose other end is grounded, are connected to a through a resistor R4, and control amounts according to the operation of the sticks 2 and 3. It is possible to introduce it. The mixing section 14a also includes a trim volume 4a made of a variable resistor whose negative end is connected to the DC power supply B and whose other end is grounded.

As a result, the mixing section 14a
The two systems of signals, the control amount by trim 7.8 and the correction amount by trim 7.8, are mixed and adjusted and output to the encoder IC 14b.

The encoder TC 14b sets a traveling speed signal or a traveling direction signal to the receiver of the radio-controlled car based on the output of the mixing section 14a, and outputs it to the transmitting circuit. A signal is sent from the transmitting stage to the receiver, thereby causing the servo motor or the steering wheel to move.

Next, the operation of the radio-controlled transmitter will be explained. When operating a radio-controlled car using the radio-controlled transmitter of the present invention, operate the trim 7.8 with the index finger or middle finger while operating the stick 2.3 with the left and right thumbs. For example, S
