PURPOSE:To obtain a prescribed level of output power, by changing the direction of a solor battery and setting the solar battery vertical to incident light if the incident light is weak. CONSTITUTION:The direction of a solar battery is variable, and therefore the solar battery is located vertically to the incident light if the intensity of the incident light is small. For instance, an arithmetic process is carried out at the inside a computer main body 1 for the data fed to a keyboard part 4 of the main body 1, and the arithmetic result is displayed at a display part 3. When the intensity of the incident light is large, a solar battery part 2 is stored in a storing part 1' provided to the main body 1. While the part 2 is taken out of the part 1' onto the main body 1 when the incident light becomes weak and also turned toward the incident light. At the same time, a draw-out rod 5 which supports the part 2 and at the same time draws the part 2 out of the part 1' is inserted into a support 6 so that it can move freely up and down. Then a support ball 7 is attached at the tip of the bar 5. Thus the part 2 can be tilted via a rotary support tool 8 which is connected to the ball 7 with the ball 7 used as a fulcrum. |
