1 does not create drive power for the device, and thus an AC100V external power supply (reference numeral 52 in FIG. 6 indicates an external power supply connection portion) as shown in FIG. 6 is required separately. Therefore, there is a problem that the device cannot be used where there is no external power supply. Further, in this conventional technique, the optical sensor 51 remains facing west even after the sun has set. Therefore, according to this conventional technique, when the sun rises the next morning, the bottom 51a of the optical sensor 51 will be exposed to sunlight, and the optical sensor 51 cannot catch the sun. There is a problem that it cannot be activated automatically.

Here, since the fixed resistance R 1 and the fixed resistance R 2 have a relationship of R 1 (Ω) = 2 × R 2 (Ω), current flows through the phototransistor 21 or 22, or the phototransistor 23 or 24, and the horizontal The rotation direction of the drive motor 4 or the advanced drive motor 5 is determined. When there is no difference in the power generation amount of the solar cell 3, the motors 4 and 5 are stopped and the generated electricity is stored in the battery 25. When the sun sets and the amount of power generation decreases, the electromagnetic switch 26 is turned on and the horizontal drive motor 4 is turned off until the limit switch 27 is turned off.
It is driven by battery power. Here, the limit switch 27 is set so that the solar cell 3 faces toward the sunrise of the summer solstice.
