PURPOSE: To provide a plane plate direction controller which can cope with even the change of the angle of elevation to the sun in the summer and winter etc., by providing a rotary drive mechanism which turns a plane plate in response to the output difference of plural photoelectric transducers and then always setting the plane plate right against the incident direction of the light. CONSTITUTION: Plural solar batteries 1b are attached on a plane plate 1a and used as a solar battery plate 1, and a light shielding plate 4 is erected on the surface of the plate 1 so that the lengthwise direction of the plate 4 is set in the vertical direction. The photoelectric transducers 6a, 6b, 7a and 7b are attached on the surface of the plate 1 and adjacent to the plate 4. The electric signals received from the transducers 6a to 7b are differentially amplified, and the rotary drive mechanisms 20 and 30 are driven. Furthermore, the plate 1 is always turned right against the sun by an automatic balancing function. Thus, it is possible to cope with the change of the angle of elevation to the sun in the summer and winter etc. |
