Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device equipped with a solar cell, and more particularly to an electronic device equipped with a solar cell that converts sunlight or indoor light into electricity and uses it as a power source. be.

The output power of solar cells installed in such electronic devices is determined in proportion to the illuminance of incident light.

Therefore, when using conventional electronic devices with solar cells in a dimly lit room, if the illuminance of the light incident on the solar cells is perpendicular to the solar cells, the electronic devices will operate normally; There is a problem that electronic devices become unusable if the angle changes. This is because even if the illuminance of the light is constant, the angle of incidence of the light when it enters the solar cell is different, so the illuminance of the light that enters the solar cell is different, and the output power decreases in proportion to it. On the other hand, if the electronic device with a solar battery is small and handy, it can be operated by adjusting the angle of the electronic device, but in the case of a large electronic device such as a tabletop type, it is difficult to operate due to the operability and placement on the tabletop. The electronic device cannot be placed in a location where the illuminance of light incident on the solar cell of the electronic device is maximized, and the output power of the solar cell does not reach a predetermined value, making the electronic device unusable.

Therefore, the present invention overcomes these conventional drawbacks and
To provide an electronic device with a solar cell that can be used even in a dimly lit place.

In order to achieve this objective, the present invention provides a configuration in which the solar cells can be pulled out from the main body of the device, and the illuminance of the light incident on the solar cells can be adjusted to the maximum depending on the angle of the incident light. Ta.

The present invention will be described in detail below with reference to the accompanying drawings.

In FIGS. 1 and 2, the reference numeral 1 indicates a solar cell that converts light into electricity and supplies electric power. As will be described later, this solar cell 1 is in the folded state shown in FIG. 1. can be pulled out as shown in FIG. The electronic device operates with the power supplied by the solar cell 1, and various data are input by pressing various keys arranged on the keyboard 4, and the arithmetic processing unit ( (not shown), and the results are displayed on a display 3 made up of, for example, a liquid crystal or a light emitting diode.

Furthermore, a level meter 5 is provided in the upper left part of the display 3 to display the illuminance of light incident on the solar cell. For example, the method of displaying this illuminance with a level meter is disclosed in Patent No. 8.
11292, a solar cell is used as a detector of illuminance, and the output voltage of the solar cell is converted to DC/
This is done by performing AC conversion, dividing this AC voltage, and applying it to each level of a level meter.

The solar cell 1 described above is shown in FIGS. 2 and 3(a).

(As shown in detail in FIG. 1), the support 7 is pulled out from the electronic device 2 or stored via a pull-out rod 6 that is supported so as to be able to move up and down.

The upper end of this pull-out rod 6 is joined to a ball 8, and a rotating body 9 is fixed to the back surface of the solar cell 1. A slit 11 is provided in the center of the four sides of the rotating body 9. When the ball 8 is press-fitted into the rotating body 9 through the slit 11, the lower diameter of the rotating body 9 expands and the ball 8 becomes the rotating body. The diameter of the lower side of the rotating body 9 incorporating the ball 8 returns to its original diameter, and the rotating body 9 becomes non-removable. The rotating body 9 engaged with the ball 8 in this manner becomes able to slide freely on the ball 8, and the solar cell section 1 becomes movable left and right and back and forth.

On the other hand, what is indicated by the symbol 10 is the power supply line of the solar cell,
This power line 10 is wired inside the rotating body 91, the bulb 8, and the pull-out rod 6, and is connected to the main body of the device.

In such a configuration, if the illuminance of the light incident on the solar cell 1 is greater than the power consumption of the main body of the device, the solar cell 1 is housed in the main body of the electronic device 2 as shown in FIG. The surface is almost the same as the surface of the main body.In such a state, the illuminance decreases and when the level meter 5 indicates a certain value or less, the electronic device 2 stops operating.

If the electronic device 2 cannot be used due to the angle of light incident on the solar cell 1, pull out the solar cell 1 from the electronic device 2 as shown in FIG. , and adjust the solar cell 1 so that the level meter 5 indicates the maximum value. This allows the solar cell 1 to increase the power supply,
The electronic device 2 can be operated normally.

As explained above, according to the present invention, the solar cell can be pulled out from the main body of the electronic device, and the photoelectric conversion surface of the solar cell can be freely oriented in a predetermined direction. The angle of light can be set to the optimal incident angle, and even if electronic equipment stops working due to insufficient illuminance, the solar cells can be directed in the optimal direction while watching the level meter to expand the power supply of the solar cells, allowing the electronic equipment to can operate normally.
