Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a battery cover that closes a battery chamber formed in the main body of an electric camera.

B. Prior Art Electric cameras to which a power supply pack or a long film bag can be attached have been known. In this type of camera, a power connector for receiving power from a power pack and a long film back connector for supplying power, control signals, etc. to the long film back are provided in advance on the camera body. Electric cameras are also known that have a vertical release button and a remote terminal on the camera body.

On the other hand, in this type of electric camera, the battery chamber formed in the camera body is closed by a separate battery cover, and the battery is kept in place by the battery cover, and the contacts provided on the battery cover etc. It is connected to the load inside the camera body via etc.

C Problems that the invention aims to solve However, if all the electrical parts such as various connectors, terminals, and vertical release buttons are installed in the camera body in advance, the camera body will become larger and more expensive, and the appearance will be spoiled. . Moreover, not all camera users require all of these electrical components.

On the other hand, the battery lid has only the function of keeping the battery in place and connecting the battery to a load, and its outer surface has not been used effectively.

An object of the present invention is to provide a battery cover for a camera that can accommodate various functions.

D Means for Solving the Problems The present invention will be explained with reference to FIGS. 1 and 2 showing an embodiment. This is applied to camera battery covers 10 and 20 that close the battery chamber 1 when attached. With the above installation, at least one of the battery contacts 13 and 14 connected to the battery 2 housed in the battery chamber 1, the release button 16, and the connector 15 that receives an electrical signal from an external device, and the release button are connected to each other. 1
The above-mentioned problem can be solved by preparing a plurality of battery covers 10 and 20 having connection terminals 17 and 27 that transmit a release signal generated in response to the pressing of the button 6 or an electric signal transmitted via the connector 15 to the camera body 50. Solve the points.

E Function When the battery cover 10 is attached to the camera body 50, the battery 2 housed in the battery chamber 1 is fixed, and
The power source of the battery 2 is connected to the camera body 50 through contacts 13 and 14 . Electrical parts installed on the outside,
For example, a remote switch is connected to the remote connector 15, and a release signal is supplied to the camera body 50 via the connector. When using a long film bag, a battery cover 20 may be used.

F Example An embodiment will be described with reference to FIGS. 1 and 2.

The battery lid 10 shown in FIG.
4, a remote connector 15 provided on the camera front side surface 11a of the lid body 11, and a vertical release button 1 provided on the main body side surface 11b forming 45 degrees with the camera optical axis.
6, and a signal contact 17 that supplies electrical signals from the remote connector 15 and the vertical release button 16 to the camera body 50. The battery cover 10 is attached to the camera body 50 by locking its mounting claw 12 to a camera body side locking portion (not shown), and forms a battery chamber 1 between the battery cover 10 and the camera body 50. Battery contact 1
A pair of battery contacts 51 and 52 are provided on the camera body 50, facing the signal contacts 17, and a camera-side signal contact (not shown) is provided on the camera body 50, facing the signal contact 17.

When the batteries 2 are loaded into the battery compartment 1 and the battery cover 10 is attached to the camera body 50, the two batteries 2 are fixed in the battery compartment 1, and the battery contacts 13, 14, 51, 5
Both batteries 2 are connected in series via 2, and power is supplied to loads such as various motors in the camera body 50. Further, the signal contact 17 is connected to a signal contact on the camera side, and a release signal generated by operating a release switch connected to the remote connector 15 is transmitted to a control circuit, etc. in the camera body 50 via both signal contacts. Further, a release signal generated by operating the vertical release button 16 is also transmitted to a control circuit within the camera body 50 through both signal contacts.

On the other hand, in place of the battery cover 10 shown in FIG.
A battery lid 20 shown in the figure can be used.

The battery cover 20 shown in FIG. 2 has a long film back connector 22 provided on the camera front side surface 21a of the main body 21. A cord (not shown) is connected to this connector 22 to connect the long film bag and the camera body 50. Release signals from these connector vertical position release buttons 16 are supplied to the control circuit of the camera body 50 and the like via a battery contact 27 inside the battery cover 20. The rest of the structure of the battery cover 20 is the same as that shown in FIG. 1, and the explanation thereof will be omitted.

Therefore, the camera body does not need to be previously equipped with electrical parts for various additional functions (accessories), and the camera body can be made smaller, reducing costs and improving its appearance. On the other hand, camera users purchase only a battery cover that matches the camera body and desired functions, or purchase two battery covers 10, 2.
You can purchase 0 of each and use them as needed.

Note that electrical components related to various functions other than those described above may be provided.

G Effect of the invention According to the invention, at least two or more electrical components related to additional functions of the camera are attached to at least two or more battery covers, and power supply, control signals, etc. are transmitted to the camera body via the battery covers. Since the camera body can be supplied with the camera body, there is no need to provide such electrical parts in advance, which results in miniaturization and cost reduction, and also improves the appearance.
