Abstract

A video camera is provided with both a liquid crystal display as well as a smaller conventional eyepiece type viewfinder. Switching means responsive to an opening movement of the liquid crystal display from a closed position are used to automatically and smoothly switch off the viewfinder, switch on the liquid crystal display and to enable a speaker. The liquid crystal display is also used as a cover for relatively infrequently used setting switches and controls.

Claims

1. A video camera comprising:

a liquid crystal display for displaying an image; and

a view finder for displaying an image;

wherein said liquid crystal display is mounted on said video camera with a pivotal mounting so as to open and close against a side of said video camera;

said camera further comprising a switch responsive to pivotal movement of the liquid crystal display for switching the image which is displayed between said liquid crystal display and said view finder.

2. A video camera as set forth in claim 1, wherein said liquid crystal display can display an image being recorded or an image reproduced from a video tape disposed in said video camera.

3. A video camera as set forth in claim 1, further comprising a display portion of said liquid crystal display, said display portion being recessed from a front surface of said liquid crystal display.

4. A video camera as set forth in claim 1, wherein said liquid crystal display is pivotal in an opening direction in a range of 130°

±

5°

about an axis of said pivotal mounting.

5. A video camera as set forth in claim 1, further comprising a rotating means interposed between the liquid crystal display and said pivotal mounting, said rotating means allowing said liquid crystal display to rotate in a direction perpendicular to an axis of said pivotal mounting.

6. A video camera as set forth in claim 5, wherein, when said liquid crystal display is open, said rotating means allows said liquid crystal display to rotate in a clockwise direction and a counterclockwise direction by 90°

, respectively.

7. A video camera as set forth in claim 6, wherein said rotating means include a detent means for providing a perceptible click when said liquid crystal display means is rotated.

8. A video camera as set forth in claim 1, further comprising a setting switch group disposed on a side surface of the video camera which is covered by the liquid crystal display when said liquid crystal display is closed.

9. A video camera as set forth in claim 1, further comprising a speaker for reproducing an audio signal from a video tape, said speaker being arranged on a side surface of the video camera body which is covered by said liquid crystal display when said liquid crystal display is closed.

10. A video camera as set forth in claim 9, wherein said speaker is electrically connected with a source of said audio signal by said switch so as to output sound only when said liquid crystal display is open.

11. A video camera as set forth in claim 1, further comprising a damage-resistant surface provided adjacent to the pivotal mounting on said side of the video camera which is covered by the liquid crystal display when said liquid crystal display is closed.

12. A video camera as set forth in claim 11, wherein said damage-resistant surface comprises a plurality of projections.

13. A video camera as set forth in claim 1, further comprising a locking means for maintaining said liquid crystal display in a closed condition, said locking means being provided between a body of said video camera and said liquid crystal display.

14. A video camera as set forth in claim 1, further comprising a connection for supply an image signal to said liquid crystal display, wherein said connection is governed by said switch and is enclosed in an interior portion of said pivotal mounting.

15. A video camera comprising:

a camera body adapted to receive a tape cassette;

an eyepiece type view finder, said viewfinder including a first liquid crystal display;

a second liquid crystal display, larger than said first liquid crystal display, hingedly mounted on a side of said camera body, said second liquid crystal display being pivotal between a closed position and an open position; and

switching means responsive to opening and closing of said second liquid crystal display for switching an image signal between said first liquid crystal display to said second liquid crystal display when said second liquid crystal display means is opened and closed.

16. A video camera as set forth in claim 15, further comprising a speaker, said speaker being enabled to produce an audio signal when said second liquid crystal display is opened by a predetermined amount from a fully closed position and disabled when said second liquid crystal display is not open more than said predetermined amount.

17. A video camera as set forth in claim 15, wherein said switching means switch said image signal between said first liquid crystal display and said second liquid crystal display when said second liquid crystal display is opened a predetermined amount.

18. A video camera as set forth in claim 17, wherein said predetermined amount is seven degrees.

19. A video camera as set forth in claim 15, further comprising a noise prevention circuit which prevents noise from being recorded on said tape cassette when said switching means switch said image signal between said first liquid crystal display and said second liquid crystal display.
