Abstract

PURPOSE:To provide an improved protective cover by considering that charging is impossible in a state where a camera is put in a pocket because of structure where a solar battery holding body can not be detached from the protective cover in the conventional camera provided with a protective cover. CONSTITUTION:1 shows a camera, 2 shows a protective cover main body, and 3 shows the solar battery 3a holding body. The solar battery holding body 3 is attached to the main body 2 by inserting a spring state clasp piece 3b in the slit 2b of the main body 2 and allowing it to press-contact with a shelf board 2d. By clasping the holding body 3 on a coat pocket by the clasp piece 3b in a state where the holding body 3 is detached from the main body 2, charging is executed to the camera in the pocket while the solar battery 3a in the holding body 3 is irradiated with sunlight.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective cover for a portable device, and more particularly to a portable device to which a solar electromagnetic holder having a solar cell (solar cell) on its outer surface is detachably mounted. Regarding the protective cover of.

[0002]

2. Description of the Related Art Recently, products such as wristwatches and card calculators (or card-type calculators) that are extremely small and consume less power are increasingly equipped with solar cells.
Products larger than these products and having large power consumption, such as mobile phones, cameras, and portable personal computers, have not been commercialized with solar cells. This is partly because the output of the solar cell is small and the price is high.

However, considering that, for example, a camera is an international commodity that is often used in remote areas of the world and is often used in a place where dry batteries cannot be obtained, a camera with a solar cell is provided. I needed a camera. Further, recently, due to improvement in performance and manufacturing technology of the solar cell, the cost per output of the solar cell has been considerably reduced, and therefore it has become possible to equip a relatively large product.

Therefore, the present applicant has proposed in Japanese Patent Application No. 5-140686 a camera having a protective cover with a solar cell.

The above-mentioned prior art camera and protective cover by the present applicant will be described below with reference to FIGS. 8 to 11.

8 to 11, reference numeral 51 denotes a camera having a collapsible lens barrel, and a rechargeable lithium ion secondary battery 54 is housed in the camera 51. A hinge portion 55 for attaching the protective cover 52 is provided on the right side surface of the camera 51 so that the protective cover 5 can be attached to the hinge portion 55.
The second hinge shaft 52a is rotatably supported, and the hinge cover 55 allows the camera cover 51 to rotate.
Installed on. The protective cover 52 is formed in a box shape so as to completely shield the front surface of the camera 51 and cover a part of the side surface, the top surface and the bottom surface of the camera 51.
A solar cell 53 made of an amorphous silicon semiconductor is fixed to the outer surface of the portion covering the camera surface. Solar cell 5
3 is connected to the backflow prevention diode in the camera 51 via the wiring in the cover 52 and the hinge shaft 52a and the hinge portion 55 of the camera 51, and is further connected to the battery 54 via the diode. As shown in FIG. 10, the front surface of the cover 52 is inclined in the left-right direction with respect to the front surface of the camera 51, and a projection 56 provided on the back surface of the cover 52 forms a gap 57 between the front surface of the camera and the front surface of the camera. Has been formed. The gap 57 has a cross-sectional area expanding from the left side to the right side of the camera and communicates with a ventilation hole 58 penetrating the right end of the front surface of the cover 52. The air that has entered the gap 57 from between the left side surface of the camera 51 and the left end portion of the cover 52 located on the left side surface of the camera is warmed and expanded in the front surface of the camera. It flows in a large direction (that is, in the direction of the arrow), and finally flows out of the cover 52 through the ventilation hole 58. Therefore, the temperature is naturally adjusted so that the temperature of the gap 57 between the front surface of the camera and the front portion of the protective cover 52 does not rise excessively. Further, a stroboscopic light emitting section 59 is arranged at the front right corner of the camera corresponding to the ventilation hole 58 of the protective cover 52,
The light rays that enter the protective cover 52 through the ventilation holes 58 are reflected by the strobe reflection shade in the stroboscopic light emitting portion 59 to prevent the temperature of the camera from rising due to the incident light rays and heat the air passing through the ventilation holes. As a result, the air flowing out of the ventilation hole 58 is accelerated to improve the air flow in the gap 57.

In addition, a total of 4 is provided in the four corners on the back surface of the camera 51.
The projections 61 are provided so that when the camera 51 is placed on a surface having a high temperature (for example, a dashboard of a car parked in the hot sun), the heat of the surface is reflected by the camera 5.
It is for making it difficult to be transmitted to 1. 60
Is a heat insulating material adhered to the back surface of the cover 52.

Assuming that the camera is exposed to direct sunlight in a car in hot weather in summer as the most severe condition for high temperature, experimentally the surface of the camera in Japan will be 70 ° C. or higher, and the protection as described above will occur. In a conventional camera without a cover, the temperature inside the camera rises above 60 ° C.

On the other hand, the lithium ion battery has a characteristic that the electrolyte deteriorates and the charge capacity decreases in an environment of 60 ° C. or higher.

Therefore, in the conventional camera, the charging capacity of the lithium-ion battery inside the camera is surely reduced when the above-mentioned usage is used, but the applicant of the present invention having the above-mentioned protective cover. According to the prior art camera, the temperature of the gap 57 between the front surface of the camera 51 and the front portion of the protective cover 52 is 5 even under the above high temperature.
It can be held at about 5 ° C.

[0011]

In the above-mentioned prior art camera of the applicant, when the camera is put in a pocket of clothes or a camera case, the solar cell cannot be exposed to the external light, and the protective cover is not provided. Since 52 cannot be easily removed from the camera, it has not been possible to charge only the solar cell by hooking it on a window curtain or the like.

It is an object of the present invention to overcome the above mentioned problems of the prior art and to provide an improved protective cover.

[0013]

In order to solve the above-mentioned problems existing in the prior art, in the present invention, a solar cell holder having a solar cell attached is constructed so that it can be easily removed from the protective cover body. The solar cell holder removed from the protective cover body was configured so as to be easily pinched in a pocket of clothes or an eaves of a hat.
