いた。 Conventionally, when constructing an infrared transmitting/receiving device and controlling it remotely, a voltage conversion circuit 11 such as a switching regulator or a DC-DC converter circuit is used, for example, as shown in FIG. 3, in order to reduce the volume of the power supply battery. , the frequency 1 of the infrared control signal was set to a high frequency with respect to the operating frequency 2 of the voltage conversion circuit, but as shown in Figure 4, the harmonic distribution of frequency 2 of the voltage conversion circuit was in the frequency domain of the control signal. They have the disadvantage of being spread out and causing mutual harmonic interference. In order to eliminate this harmonic interference, a high-pass filter 12 is usually provided on the output side of the voltage conversion circuit 11 as shown in Fig. 3, but the structure becomes complicated and the original purpose of reducing the volume of the power battery is On the other hand, it has drawbacks such as an increase in the area occupied by the voltage conversion circuit 11 and the high-pass filter 12.

送出するものである。 The present invention eliminates the drawbacks of the above conventional type.
The present invention will be described with reference to an embodiment shown in the figure below. Reference numeral 1 denotes an amplifier circuit, and the input side of the amplifier circuit 1 is provided with a photodiode 2 for receiving an infrared control signal and converting it into an electric signal. , a switching circuit 3 for the controlled motor M is connected to the output side X thereof. On the other hand, the switching circuit 3 is provided with a battery 4 that serves as a power source for the motor M, and if the battery 4 is set to, for example, 1.5V, this 1.5V
A constant voltage conversion circuit 5 is provided for commonly using the battery 4 and converting it into a predetermined DC voltage, for example 9V, and supplying the voltage to the amplifier circuit 1. This constant voltage conversion circuit 5 is composed of, for example, a switching regulator or a DC-DC converter circuit, and FIG. 5 shows transistors Tr 1 , Tr 2 ,
An example of a DC-DC converter circuit including a transformer T, resistors R 1 , R 2 , capacitor C, rectifying silicon diodes D 1 , D 2 , output voltage stabilizing Zener diode ZD, etc. is shown. In the same figure, the input terminal
When 1.2 V DC is applied to IN and the common ground terminal oUT, 9 V DC is output from the output terminal oUT.
Set the frequency sufficiently higher than 2 , that is, 1 > 2 . The transmitter 7 sends a control signal to the switching circuit 3 that controls the rotation of the motor M using infrared rays.

与えるようなことはない。 With the above configuration, by setting the oscillation frequency 1 of the voltage conversion circuit 11 to a frequency sufficiently higher than the frequency 2 of the infrared control signal, the harmonic distribution of each frequency 1 and 2 is formed as shown in Fig. 2. However, especially since the distribution of subharmonic components of frequency 1 is rapidly attenuated, both frequencies 1 and 2
If the frequency intervals are set appropriately, they will not interfere with each other.
従つて、赤外線による制御信号の周波数2に拘

数1をより高くすることが可能となる。 Therefore, regardless of the frequency 2 of the infrared control signal, it is possible to make the oscillation frequency 1 of the DC-DC converter circuit higher in order to make the DC-DC converter circuit smaller and more efficient.
