いることになる。BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. (A) FIG. 1 is an outline of an optical comparison amplifier circuit, which includes a light receiving element (3), comparison amplifiers (1) and 2 and output relays (4-1, 4-2, 4-3, 4) corresponding to the respective elements. -4). (B) In FIGS. 2 and 3, the light receiving element (3) is used for the left and right PAs, PBs.
And the front and rear PCs and PDs, which are arranged in the part divided by the partition plate (6). (C) FIG. 4 is an explanatory diagram of the position of sunlight (9-1, 9-2, 9-3), the operation of the optical sensor (10), and the attitude control device in the left-right direction. Battery panel (17), light receiving plate (11), motor (15), gear (1
3), a drive shaft (12), a bearing (14) and a frame (16). (D) FIG. 5 is a right side view of the attitude control device in the front-rear direction,
In addition to the parts in (c), the motor (18) for front and rear drive,
It consists of a gear (19) and a drive shaft (20). (E) Motors (15) and (18) for controlling the front-rear and left-right postures of the front (c) and (d) are connected as shown in FIG. (1
5) is a left / right motor, and (18) is a front / rear motor. The operation will be described below. In FIGS. 1, 2 and 3, the light receiving element (3) is placed on the left side of the partition plate (6) by P.
A, PB is arranged on the right side, and when the light hits from the right direction, PA becomes the shade of the partition plate (6), and the light hitting PB is stronger, so the change in the internal resistance of PB is large, and the corresponding output The relay XB (4-2) operates. When light is applied from the left, the output relay XA (4-1) also operates. When equal amount of light strikes PA and PB of the light receiving element (3) from the front,
The output of the comparison amplifier 1 disappears, and the output relay XA (4-
1) and the output relay XB (4-2) do not operate. The operations of the PC and PD in which the light receiving element (3) is arranged in the front-rear direction and the corresponding output relays XC (4-3) and XD (4-4) are the same as above. Next, the movement of the attitude control device when the optical sensor (10) and the solar cell panel (17) are mounted will be described. In the attitude control device of FIG. 4, when the sunlight (9-1) hits the optical sensor (10) from the right direction, the output relay XB (4-
2) operates, so in the electric circuit of FIG. 6, the left / right motor (15) outputs (+) to the output XA (4-1).
Since a negative voltage is applied from the B contact, (-) through the A contact of the output relay XB (4-2), the motor (15) rotates in the reverse direction and the gear (13) and the drive shaft (12) rotate. Reverse rotation. Further, since the light receiving plate (11) is attached to the drive shaft (12), it faces the direction of sunlight (9-1). Optical sensor (1
0), the solar cell panel (17) is also attached to the surface of the light receiving plate (11), and therefore faces the same direction. When facing the sunlight (9-1), the light receiving element (3) inside the optical sensor (10)
Since PA and PB receive an equal amount of light, the left and right are balanced and the output relay XB (4-2) returns. When the output relay is restored, the motor (15) in FIG. 6 has no voltage and therefore stops at that position. Then the sun (9-1)
When is moved to the left and comes to the direction of (9-2), the light hitting the optical sensor (10) becomes stronger in PA than in PB of the light receiving element (3), so that the output relay XA (4-1) Operate. Therefore, the motor (15) is connected to the output relay XB from (+).
Output relay XA (4-) from B contact of (4-2), (-)
A positive voltage is applied through the A contact of 1), the motor (15) rotates positively, and the gear (13) and the drive shaft (12) are rotated.
Also rotates forward. Therefore, the light receiving plate (11), the optical sensor (10) and the solar cell panel (17) which are interlocked with the drive shaft (12) also face the direction of the sunlight (9-2). At this time, since the PA and PB of the light receiving element (3) inside the optical sensor (10) receive an equal amount of light, the output relay X is balanced.
A (4-1) is restored, the voltage applied to the motor (15) is lost, and the motor (15) stops at that position. This series of movements follows the movement of sunlight (9-1, 9-2, 9-3) and is repeated. Therefore, the light receiving plate (11) and the optical sensor (10)
And the solar cell panel (17) is always facing the sunlight. Also, regarding the front-back direction control of FIG. 5, the P of the internal light receiving element (3) of the optical sensor (10) is the same as above.
C, PD and its output relays XC (4-3), XD (4-
The movement of 4) is the same. Motor (18) and gear (1
The movements of 9), the drive shaft (20) and the light receiving plate (11) are also the same, and always face the sunlight (9-1, 9-2, 9-3).
