These guides 43, 44, and 45 allow the first support 31 to move relative to the second support 32, that is, the solar panel 13 to rotate relative to the frame 11 and move linearly in the vertical direction. can be regulated.

When the solar panel 13 is used, that is, when sunlight is to be received, as shown in FIG. , 42 (FIG. 4) to fix the first support 31 to the second support 32 . When storing the solar panel 13, loosen the first and adjustment parts 41 and 42 (Fig. 4), and turn the main surface toward the outside of the device in the order shown in Figs. The first support portion 31 is moved with respect to the support portion 32 . On the other hand, when the solar panel 13 is changed from the housed state to the used state, the solar panel 13 is attached to the second support portion 32 with the main surface facing the outside of the device in the order shown in FIGS. In contrast, the first support portion 31 may be moved. Note that the movement of the solar panel 13 can be manually performed by an operator.

In the state between FIGS. 3A and 3B, the second shaft portion 34 of the solar panel 13 is moving in the rotational direction around the first shaft portion 33 . In FIG. 3B, the second shaft portion 34 is located at the highest position in the vertical direction. At this time, the main surface of the solar panel 13 faces the outside of the device and is parallel to the horizontal direction. In the state between FIGS. 3(a) and 3(b), the solar panel 13 can be fixed at a predetermined angle to receive sunlight.

Here, the mechanical section 14 according to the present embodiment and the mechanical sections 14A and 14B examined by the inventors will be compared with reference to FIG. Unlike the mechanism section 14, the mechanism section 14A does not have a guide section for linearly moving the solar panel 13 (first support section 31) in the vertical direction. Therefore, in terms of the height of the frame 11 as a reference (height of the device when housed), the height Ha when the mechanism portion 14A is applied remains higher than the height H when the mechanism portion 14 is applied, and the solar panel 13 will be accommodated. Therefore, by applying the mechanism part 14, it is possible to accommodate the apparatus more compactly than the mechanism part 14A at the height of the device when it is accommodated.

Further, unlike the mechanism section 14, the mechanism section 14B does not include a guide section for linearly moving the solar panel 13 (the first support section 31) in the vertical direction. Further, while the mechanical part 14 has the first supporting part 31 at the central part of the back surface of the solar panel 13, the mechanical part 14B has the first supporting part 31 at the end part of the back surface of the solar panel 13 .

In the height with respect to the frame 11, the height Hb to which the mechanism portion 14B is applied is lower than the height Ha to which the mechanism portion 14A is applied. However, since the mechanism part 14B does not have a guide part extending in the vertical direction, the solar panel 13 is accommodated while being higher than the height H to which the mechanism part 14 is applied. Therefore, by applying the mechanism section 14, the apparatus can be accommodated more compactly than the mechanism section 14B at the height of the device when it is accommodated.

Further, by applying the mechanism portion 14, the moment to rotate can be reduced more than the mechanism portion 14B. In addition, by applying the mechanism part 14, the bias of the center of gravity of the solar panel 13 can be eliminated more than the mechanism part 14B, the weight can be balanced, and the moving work can be facilitated. It should be noted that the height H of the mechanism section 14 can be further reduced by providing the first support section 31 at the end of the rear surface of the solar panel 13 in the same manner as the mechanism section 14B.

(Second embodiment)
In the first embodiment, a case has been described in which an operator manually supports the solar panel 13 when linearly moving the solar panel 13 in the vertical direction. In this embodiment, a case in which a support portion is provided to move the solar panel 13 more stably will be described with reference to the drawings. FIG. 6 is a diagram schematically showing a main part of the display device 10A according to this embodiment as viewed from the rear.

The display device 10A includes an expandable section 51 (for example, an air damper, a spring, etc.) having elasticity as a support section. The expandable portion 51 supports the first shaft portion 33 entering the first guide portion 43 (FIG. 3) from below in the vertical direction. Specifically, one end of the expandable portion 51 is fixed to the frame 11 and the other end is fixed to the first shaft portion 33 .

When the operator moves the solar panel 13 downward in the vertical direction, the expansion/contraction part 51 contracts while supporting the first shaft part 33, so that it can be easily moved. As a result, the solar panels 13 can be well organized and easily accommodated. Moreover, when the operator moves the solar panel 13 upward in the vertical direction, the expansion and contraction part 51 extends while supporting the first shaft part 33, so that it can be easily moved.

(Third embodiment)
In the first embodiment, a case has been described in which an operator manually supports the solar panel 13 when linearly moving the solar panel 13 in the vertical direction. In this embodiment, a case where a stopper portion is provided to more stably accommodate the solar panel 13 will be described with reference to the drawings. FIG. 7 is a diagram schematically showing a main part of the display device 10B according to the present embodiment as viewed from the right side.

The display device 10B includes a stopper portion 52 that holds the solar panel 13. As shown in FIG. The stopper portion 52 has a first sloped portion 53 and a second sloped portion 54 that form a pair. Specifically, the stopper portion 52 includes a first inclined portion 53 having a first inclined surface 55 and a second inclined portion 54 having a second inclined surface 56 that contacts the first inclined surface 55 . . The first sloped portion 53 is provided at the back surface end (bottom end in the vertical direction) of the solar panel 13 when the solar panel 13 is in the housed position (the rear position of the frame 11), and is inclined downward in the vertical direction. On the other hand, the second sloped portion 54 is provided on the frame 11 when the solar panel 13 is in the housed position (the rear position of the frame 11 ), and slopes upward in the vertical direction so as to contact the first sloped portion 53 .

When the operator moves the solar panel 13 downward in the vertical direction, the first sloped portion 53 slides into contact with the second sloped portion 54 to stop the movement of the solar panel 13. can. Also, the solar panel 13 can be accommodated without contacting the frame 11 . Further, since the solar panel 13 is fixed to the frame 11 by the stopper portion 52, it is possible to suppress the generation of vibration noise when the display device 10 is transported, for example, by a light truck.

Although the present invention has been specifically described above based on the embodiments, it goes without saying that the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the scope of the invention.

For example, in the above embodiments, the solar-driven device is applied to a display device having a display panel driven by electric power. The present invention is not limited to this, and can be effectively applied to any device provided with an electric device driven by electric power.
