SUMMARY OF THE INVENTION Such conventional remote control devices have the following drawbacks. ■Remote controller U
If you keep pressing the P button or the DOWN button, the volume will continue to rise or fall, respectively, but even if you stop pressing the button, the volume will not stop rising or falling immediately, so there is a risk of going too far from the desired volume. There is. ■If there is no sound being emitted from the television receiver's speakers, the volume cannot be adjusted remotely. In this case, if you can see the rotation of the volume adjustment knob on the television receiver, you know that the volume is changing, but the degree of the volume is not certain. ■If you reduce the amount of change in volume caused by pressing the UP or DOWN button on the remote control for a short time, the amount of change from the desired volume will be reduced when adjusting the volume, but on the other hand, the current volume will change slightly. It takes a long time to reach the desired volume. Also, on the contrary, if the remote controller is
If you increase the amount of change in volume caused by pressing the button or DOWN button for a short time, the time it takes to reach the desired volume from the current volume will be shortened, but on the other hand, when adjusting the volume, you may find yourself overshooting the desired volume. The degree of this becomes large.

[Embodiment] Referring to FIG. 1, an embodiment in which the present invention is applied to a television receiver will be described in detail below. Figure 1
In the figure, 1 is a remote controller (commander), and 2 is a controlled device 2 built into a television receiver.

First, the remote controller 1 will be explained. 3
is a dial for adjusting the volume, and a part of its periphery is provided with a pointer 6, and around the dial 3, a scale 5 indicating the volume of the volume is attached on a panel 4. It is assumed that the dial 3 is located at the first reference rotation angle position when the pointer 6 coincides with the reference position of the scale 5 (not shown). A digital encoder 7 (which may be composed of an analog encoder and an A/D converter) generates numerical data corresponding to the first rotation angle of the dial 3 from the first reference rotation position. 8 is a microcomputer having a modulator (encoder) and other functions, and the modulated (encoded) numerical data from this is supplied to an infrared light emitting element 9 such as an infrared light emitting diode, from which an infrared signal is transmitted (radiated). ) to be done.

Next, the controlled device 2 will be explained. 1

is supplied to

Reference numeral 15 denotes a rotated body, which is not shown, but is composed of a volume adjustment dial and a variable resistance for volume adjustment, and a friction piece 16 that contacts a part of its periphery.
The rotation is regulated by this. It is assumed that the rotated body 15 is at the second reference rotation angle position when the mark 17 attached thereto coincides with the reference position 18 of the fixed part. A DC motor 14 is connected to the rotating body 15 through an axis AX, and rotates the rotating body 15. Reference numeral 13 denotes a variable DC voltage generation circuit, from which DC voltage is applied to the DC motor 14.

Reference numeral 19 is a potentiometer, which is connected to the rotated body 15.
A rotation angle position detection signal is generated in accordance with a second rotation angle from a second reference rotation angle position. Potentiometer 19 is a ring-shaped resistor 2 connected between power supply +B and ground.
1 and a slider 20. 12 is a control device;
The voltage corresponding to the numerical data from the microcomputer 11 and the voltage Vout of the rotation angle position detection signal from the slider 20 of the potentiometer 19 are compared, and a comparison voltage Vr based on the comparison result is applied to the drive signal generation circuit 13. The rotatable body 15 of the controlled device 2 is thereby controlled according to the second rotation angle of the dial 3 of the remote controller 1 from the first reference rotation angle position. A voltage Vi is applied to the DC motor 14 to rotate it so that the DC motor 14 is positioned at a second rotation angle from a second reference rotation angle position. The voltage Vout of the rotation angle position detection signal from the slider 20 of the potentiometer 19 is the voltage corresponding to the numerical data from the microcomputer 11 and the voltage Vout of the rotation angle position detection signal from the slider 20 of the potentiometer 19. When the voltage Vout matches the voltage Vout, the voltage Vi applied to the motor 14 becomes 0, the motor 14 stops, and the rotated body 15 of the controlled device 2 is rotated by the dial 3 of the remote controller 1.
It stops at a second movement distance from the second reference rotation angle position, which corresponds to the second rotation angle from the first reference position.

This embodiment has the following advantages. ■If you keep turning the dial 3 of the remote controller 1 in one direction or the other, the volume will continue to rise or fall, respectively, but when you stop turning the dial 3, the rotated body 15 of the controlled device 2 will Since it stops immediately, there is no risk of going too far from the desired volume. ■Even when no sound is emitted from the speakers of the television receiver, the level of volume can be determined by the rotation angle position of the dial 3 of the remote controller 1, making it possible to adjust the volume. ■By reducing the amount of change in volume caused by a short time operation of dial 3, it is possible to reduce the degree of deviation from the target volume when adjusting the volume, and also to reduce the amount of change between the current volume and the target volume. Even if there is a large difference in the volume, the desired volume can be quickly achieved.

In the above-described embodiment, the rotated body 15 was composed of a volume adjustment dial and a variable resistor for volume adjustment. It can also be configured with a variable resistor, a channel changer, a mode changeover switch, etc. Further, the transmitting element and the receiving element may be a sonic wave transmitting element, a sonic wave receiving element, a radio wave transmitting element, a radio wave receiving element, etc., respectively. Furthermore, the operator may move in a straight line, and in that case, the object to be moved also moves in a straight line.
