Abstract

A battery coupler for use in VTR integral with a camera. The battery coupler can be mounted to the VTR integral with a camera, allows a battery to be connected thereto, and includes a shoe for mounting accessories. Therefore, if the battery coupler is mounted to the VTR integral with a camera, then a microphone, a video light or the like can be mounted to the VTR integral with a camera.

Claims

1. A battery coupler comprising:

a video light portion;

a video light battery portion; and

a coupler portion mountable to a battery mounting portion of a video camera and allowing a battery to be mounted to said video camera via said coupler portion for electrically connecting said battery to said video camera, wherein said video light portion and said video light battery portion are mounted through said coupler portion to said video camera.

2. A battery coupler as set forth in claim 1, wherein a halogen lamp is used in said video light portion.

3. A battery coupler as set forth in claim 1, wherein said video light portion is formed integrally with said coupler portion.

4. A battery coupler as set forth in claim 1, wherein said video light portion is provided in said coupler portion such that it can be popped up and that, when not in use, it can be stored within said coupler portion.

5. A battery coupler as set forth in claim 1, wherein said video light portion is removably provided in said coupler portion.

6. A battery coupler as set forth in claim 1, further including a control means for controlling the turn-on of a video light in said video light portion in accordance with the power consumption of said camera battery.

7. A battery coupler as set forth in claim 6, wherein a relay switch is used in said control means and wherein, when said power consumption exceeds a preset value, then said relay switch is put into operation to turn on said video light.

8. A battery coupler, comprising:

a video light portion,

a video light battery portion allowing a video light battery to be mounted to said video light portion for electrically connecting said video light battery with said video light portion, and

a coupler portion mountable to a battery mounting portion of a video camera and allowing a battery to be mounted thereto for electrically connecting said camera battery to said video camera,

wherein said video light portion is positioned in a mounting shoe of said video camera, said video light battery portion is mounted to said coupler portion, and there is provided a control means for enabling said video light to be turned on by the power supply of said video light battery when the power of said camera battery is above a given value and for enabling said video light to be turned off by stopping the power supply of said video light battery when the power of said camera battery is below the given value.

9. A battery coupler, comprising:

a video light portion;

a video light battery portion to which a video light battery is mounted, said video light battery portion having an electric circuit for electrically connecting said video light battery to said video light portion, and

a coupler portion mountable to a battery mounting portion of a video camera and allowing a battery to be mounted to said video camera via said coupler portion for electrically connecting said battery to said video camera, wherein said video light portion and said video light battery portion are mounted through said coupler portion to said video camera.
