Abstract

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.

Description

[Detailed description of the invention] The present invention relates to electronic equipment with solar cells.

Generally, the output power of a solar cell is determined in proportion to the amount of incident light. For example, even if the intensity of light incident on a solar cell is the same, the area of the solar cell in the vertical direction relative to the incident light will be different depending on whether the light is incident on the solar cell perpendicularly or at an angle. . That is, since the amount of incident light is different, the output power of the solar cells is different. This output power is at its maximum when the solar cell is perpendicular to the incident light, and becomes smaller as the angle of inclination with the incident light decreases.

For the same reason, when conventional electronic devices with solar cells are used in places with weak light such as indoors, when the light is incident perpendicularly to the solar cells, the specified power is obtained and the power is not normal. However, when the light is incident at an angle, the required power cannot be obtained, resulting in a problem that the load equipment cannot be used, or even if it can be used, it may cause malfunction. In such cases, if the electronic device is small, it can be dealt with to some extent by adjusting the device's position so that the solar cells face the direction of the incident light, but for large devices such as tabletop types, This was a particular problem because its position could not be changed freely due to layout and operability issues.

The present invention has been made in view of the problems of conventional electronic devices with solar cells as described above. It is desirable to propose an electronic device with a solar cell that can obtain a predetermined output power by positioning the battery perpendicularly to the incident light.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail based on the drawings. In the following description, an example will be described in which the present invention is applied to an electronic desk calculator equipped with a solar battery.

FIGS. 1 and 2 show an electronic desktop needle 3 with a solar battery according to an embodiment of the present invention! 1 is a perspective view of a computer (hereinafter referred to as a computer).

1 is the main body of the computer, 2 is its solar cell section, 3 is a display section, and 4 is a keypad section. The data inputted through the keypad section 4 is arithmetic-processed within the computer main body 1 and the result is displayed on the display section 3.

When the incident light is strong, the solar cell section 2 is stored in the storage section 1' provided in the computer main body l as shown in Fig. 1, but when the incident light is weak (see Fig. 2). As shown in FIG. 2, it is constructed so that it can be pulled out from the storage section 1' onto the computer main body l and directed in the direction of incident light.Next, the construction will be shown using FIGS. 2 to 4.

Reference numeral 5 denotes a pull-out rod for supporting the solar cell section 2 and pulling it out from the storage section 1', and is inserted and supported in a column 6 provided in the computer main body 1 so as to be movable up and down. This pull-out rod 5
By moving the solar cell part 2 up and down with respect to the support 6, the solar cell part 2 is pulled out from the storage part 1' and stored in the storage part 1'.

7 is a support ball integrally provided at the tip of the pull-out rod 5;
Reference numeral 8 denotes a rotating support that is coupled to the support ball 7 provided on the back side of the solar cell section 2. A downwardly opening receiving part 8' is formed in the rotation receiving part 8, as shown by the dotted line in FIG. 3, and is connected to the supporting ball 7. It is shaped so that more than half of it fits, and its lower opening is smaller in diameter than the support ball 7. Furthermore, cutouts 10 of a predetermined height are provided at several locations around the lower end of the rotary receiver 8, as shown in the figure, and extend from the outside of the rotary receiver 8 to the receiving portion 8'. Without this notch 10, the opening of the receiving part 8' in the rotary receiver 8 would be smaller than the diameter of the support ball 7, so it would not be possible to fit the internal pressure support ball 7 into the receiving part 8'. 10, the receiving part 8 of the rotation receiving part 8
When force is applied to push the support ball 7 into the lower opening, the opening expands due to the notch 10, and the support ball 7 is inserted into the receiving portion 8' of the rotary receiver 8 as shown in FIG. 4(a). It fits perfectly. Furthermore, after the supporting ball 7 is completely fitted into the receiving part 8', the opening of the receiving part 8' returns to the diameter of the supporting ball 7 or less, so that the rotary receiving part 8 cannot be pulled out from the supporting ball 7. It won't fall.

In addition, 9 in the figure is the power supply line of the solar cell part 2, and the rotation support 8
The support ball 7 and the pull-out rod 5 are wired and connected to the computer main body 1.

The solar cell section 2 is supported by the pull-out rod 5 by the rotation support 8 being coupled to the support ball 7 as described above. Further, due to the above-mentioned connection, the rotation receiver 8 can freely rotate around the support ball 7, so that the solar cell section 2tl can be rotated within a predetermined range in all directions with the support ball 7 as a fulcrum.
) can be tilted as shown in FIG. In this case, it goes without saying that if the pull-out rod 5 is made thinner, the solar cell section 2 can be moved over a wider range.

With the above configuration, even when the light incident on the solar cell section 2 is weak and the predetermined output power cannot be obtained because the incident light is not perpendicular to the solar cell section 7, the solar By pulling out the battery section 2 from the storage section 1' of the computer main body 1 and adjusting its orientation so that it is perpendicular to the incident light, the amount of light incident on the solar cell section 2 can be increased, thereby achieving a predetermined output. It becomes possible to obtain electric power and operate the computer main body 1 normally. Furthermore, even if sufficient incident light is obtained, if the solar cell section 2 is directed toward the incident light, the output power can be reliably obtained and the operation of the computer main body 1 can be stabilized. be able to.

As explained above, according to the present invention, the solar cell section can be freely adjusted so as to be perpendicular to the incident light. electronic equipment may stop working or malfunction. Such disadvantages can be eliminated as much as possible. Furthermore, the present invention also allows large-sized electronic equipment whose position cannot be freely changed with respect to incident light due to layout and operability to be used without any problems.
