When the operator turns the steering wheel 4 in the C direction, the steered body turns rightward, and when the operator turns the steering wheel 4 in the D direction, the steered body turns leftward. Around the steering wheel 4, a throttle trigger lever 3 and trims 5 and 6 for adjusting a neutral position of the steering wheel 4 are provided. The trims 5 and 6 are provided at positions where the steering wheel 4 is operated and can be operated with the right thumb or forefinger. Therefore, the neutral positions of the throttle trigger lever 3 and the steering wheel 4 can be adjusted while remotely controlling the steered body. Trim 5,
Reference numeral 6 denotes a well-known configuration described in Japanese Patent Application Laid-Open No. 63-1122, which is provided with one set of an up switch and one set of a down switch so that the neutral positions of the throttle trigger lever 3 and the steering wheel 4 can be easily adjusted. It is configured to be able to.

Further, in the radio control transmitter according to the present embodiment, the height of the throttle trigger lever 3 and the height of the steering wheel 4 are substantially the same. For this reason, the position of the left hand operating the throttle trigger lever 3 and the position of the right hand operating the steering wheel 4 are substantially the same height. Therefore, the operator remotely controls the steered body in a natural posture in which the radio-controlled transmitter is located substantially at the center of the body. For this reason, there is no adverse effect on the joints of the operator such as the wrist, and it is possible to prevent the health of the operator from being adversely affected. In addition, since the steered body is remotely controlled in a natural posture, the steered body is less likely to be tired, and the steered body can be remotely controlled continuously for a long time.

A display section 7 is provided on the upper surface of the main body. As shown in FIG. 6, the display section 7 displays setting data such as trim adjustment values for the throttle and steering, and status data indicating the remaining battery level and the like. The direction of the displayed character is the width direction of the main body 1. Further, below the display unit 7, for example, a control amount for changing the traveling direction of the steered body with respect to the maximum operation amount of the steering wheel 4 and a speed of the steered body with respect to the maximum operation amount of the throttle trigger lever 3 There are a plurality of keys for setting the same. FIG. 6 shows a state where the amount by which the traveling direction of the steered body is changed is set to an initial value (100%) with respect to the maximum operation amount of the throttle trigger lever 4. By operating a specific key provided below the display section 7, the displayed value of 100% can be changed to 120% or 80%. Further, by operating another key and moving the displayed cursor (in the figure, EPA of the steering wheel), the setting of other items such as the speed of the steered body with respect to the maximum operation amount of the throttle trigger lever 3 is performed. You can also change the value.

Also, in the display section 7, the set value of the trim for the steering is displayed in a bar graph in an area 11 as shown in FIG. 6, and the set value of the trim for the throttle is also displayed in a bar graph in an area 12 shown in FIG. Is displayed. The remaining amount of the battery is indicated in area 1 shown in FIG.

An antenna 8 is provided on the upper part of the main body 2, and a lower part of the grip 1 is a battery case 9 for storing a battery. The grip 1 and the battery case 9 are integrally formed.

Further, the grip 1 and the main body 2 can be easily removed as shown in FIG. 7 by removing the fixing screws. The lower portion of the main body 2 as shown in FIG. 7 is provided a recess 21 of the front and rear symmetrical, grip 1
The upper end of the main body 2 is formed with a convex portion 22 that fits into the concave portion 21 of the main body 2. Therefore, as shown in FIG. 8, the grip 1 can be attached to the main body 1 with the front and rear sides thereof reversed. In this manner, when the grip 1 is mounted on the main body 2 in an inverted manner, the steering wheel 4 is located on the right side of the radio control transmitter. In this case, the operator operates the throttle trigger lever 3 with the right hand while holding the grip 2 with the right hand, and operates the steering wheel 4 with the left hand. In other words, when the grip 1 is mounted on the main body 1 with the front and rear inverted, it can be changed to a radio control transmitter for left-handed operators. In addition,
The protrusion 22 of the grip 1 and the recess 21 of the main body 2 are fitted and then fixed with screws. This allows the grip 1
And the main body 2 do not come off. Also, the recess 21
Is provided at a position where the right and left weights of the radio control transmitter centering on the grip 1 are almost the same when the main body 2 is attached to the grip 1. Therefore, grip 1
Regardless of which direction the main body 2 is attached, the right and left weight balance of the radio control transmitter hardly changes. For this reason, the same load is applied to both hands of the operator, and the steered body can be remotely controlled in a natural posture. Further, as shown in FIG. 6, the direction of the characters on the display unit 7 is set to the width direction of the main body 2, so that the main body 2 may be attached to the grip 1 in any direction.
The displayed characters do not turn upside down for the operator. Therefore, the operator can easily check the data displayed on the display unit regardless of whether the data is used for a right-handed operator or a left-handed operator.

The operator grasps the grip 1 with the left hand from behind the radio control transmitter, and inserts the index finger of the left hand into the U-shaped portion of the throttle trigger lever 3 in front of the grip 1. The user holds the steering wheel 4 with his right hand. Here, as described above, since the height of the throttle trigger lever 3 and the steering wheel 4 are substantially the same, the operator operates the throttle trigger lever 3 and the steering wheel 4 by positioning the radio control transmitter at substantially the center of the body. I do. In other words, the operation posture of the radio control transmitter is a comfortable posture, and it is hard to be tired even if the steered body is operated for a long time. In addition, there is no adverse effect on the joints of the wrist or the like, and the health of the operator is not impaired.

Also, during the operation of the steered body, setting changes such as the amount by which the advancing direction of the steered body is changed with respect to the maximum operation amount of the throttle trigger lever 4 are changed as shown below. Without having to do it. The operator continues to operate the steered body without changing the operation posture,
By operating a key provided on the right side of the display unit 7 with the index finger or the middle finger of the hand operating the steering wheel 4,
The cursor on the display unit 7 is moved to the position of the item to be changed. Further, another key provided on the right side of the display unit 7 is operated to change the set value of the item to a desired value. Here, the display unit 7 in the radio control transmitter according to the present embodiment.
Is provided on the upper surface of the main body 2, so that the operator does not need to rotate the radio-controlled transmitter by 90 degrees as in the related art, so that the operator can display the display unit 7.
Can be displayed. That is,
The operator can check the display on the display unit 7 without changing the operation posture. Therefore, the operator can remotely control the steered body without changing the operation posture and change the set value while checking the movement of the steered body.
Similarly, the setting change of the neutral position of the throttle trigger lever 3 and the steering wheel 4 by operating the trims 5 and 6 can be performed without continuation of the operation of the steered body and without changing the operation posture. Further, the remaining amount of the battery can be confirmed without changing the operation posture.

By providing the display section 7 on the upper surface of the main body, the operator can check the display on the display section 7 without changing the operation posture. For this reason, it is not necessary to change the operation posture and remotely control the steered body in order to change or confirm data. Therefore, the operator can change the control amount with respect to the steered body and check the remaining amount of the battery in the normal operation posture. Therefore, it is possible to prevent the remote control of the steered body from being erroneously colliding with the wall or the like and being damaged by mistake.

Further, as described above, in the radio-controlled transmitter of this embodiment, since the main body 2 can be attached to the grip 1 by being turned back and forth, it can be changed to a right-handed or left-handed radio-controlled transmitter. be able to.
