BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera with a liquid crystal finder, and more particularly to a video camera with a liquid crystal finder that utilizes a transmissive liquid crystal display section of a liquid crystal viewfinder as part of a projector.

0002

2. Description of the Related Art Compact LCD-TVs that use an image pickup device (hereinafter referred to as LCD) as a display section have been known for some time. A projector has been disclosed in which this compact LCD-TV transmission type LCD is incorporated on the optical axis of the projector and the image displayed on the LCD is enlarged and projected onto a screen, etc. (Japanese Utility Model Publication No. 60-54577). .

0003

By the way, some video cameras use an LCD as a viewfinder. Therefore, it is also possible to incorporate the LCD of this video camera on the optical axis of a projector and use it as a projector. However, since the LCD used in video cameras is built into the viewfinder,
There is a problem in that it is difficult to incorporate the CD onto the optical axis of the projector.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a video camera with a liquid crystal finder in which the LCD of the video camera can be easily installed on the optical axis of a projector.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a transmissive liquid crystal display section of a viewfinder disposed in a video camera so as to be freely retractable relative to the viewfinder. The present invention is characterized in that the transmissive liquid crystal display section protrudes from the viewfinder and is inserted between the projector light source and the projection lens of the projector unit, so that the transmissive liquid crystal display section is commonly used as a part of the projector.

[0006]

[Operation] According to the present invention, the transmissive liquid crystal display section of the viewfinder can be disposed inside the viewfinder and used as a viewfinder, and the transmissive liquid crystal display section of the viewfinder can be disposed outside the viewfinder. By inserting an externally arranged transmissive liquid crystal display between the projector light source and the projection lens of the projector unit, the transmissive liquid crystal display can be used as part of the projector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a video camera with a liquid crystal finder according to the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the video camera 10 consists of a camera body 12, a viewfinder unit 14, a display unit 16, etc. The camera body 12 has a photographing lens 1 on the side.
2A and a battery mounting surface is formed at the rear. Display unit 1 is installed on this battery mounting surface.
6 is installed. A slide plate 16A is fixed to the top of the display unit 16, and an LCD 18 is provided on the left side of the slide plate 16A (see FIG. 4). A battery 17 is detachably formed at the rear of the display unit 16.

A frame 14A of the viewfinder unit 14 is provided on the slide plate 16A so as to be movable between the photographing position (see FIG. 1) and the projector position (see FIG. 4). Moreover, as shown in FIG. 2, the LCD 1 inside the frame 14A
A backlight 20 is provided in front of the LCD 18.
An eyepiece lens 22 is provided behind the lens. Therefore, the frame 14A of the viewfinder unit 14 is at the shooting position (
(see FIGS. 1 and 2), the LCD 18 becomes a display means of a viewfinder.

A projector unit 24 is shown in FIG. The projector unit 24 is attached to the mounting section 24A.
and a projector 24B, and a mounting portion 24A.
The front surface of the camera body 12 is removably attached to a battery mounting surface formed at the rear of the camera body 12. Further, a battery 17 is formed on the rear surface of the attachment portion 24A so that it can be attached and detached, and the terminals 26, 26 are electrically connected to the terminals of the battery 17. As shown in FIG. 8, the frame 2 of the projector 24B
6, lenses 28, 28 are provided at the front, and a lamp 30 is provided at the rear. Furthermore, an opening 32 is formed in the center of the frame 26 (see FIG. 5).

FIG. 6 shows a state immediately before the video camera 10 and the projector unit 24 are combined. As shown in the figure, the assembly is carried out by first holding the viewfinder unit 14 of the video camera 10 at the projector position, and then attaching the projector unit 2 to the protruding LCD 18.
4, and simultaneously connect the video camera 1.
Mounting part 24A of the projector unit 24 at the rear of the
, and electrically connect the video camera 10 and the projector unit 24 (see Figure 7).
. By combining, the LCD 18 becomes the lens 2 as shown in FIG.
8, 28 and the lamp 30, the light emitted from the lamp 30 is guided to the screen 36 via the transparent LCD 18 and the eyepieces 28, 28. Therefore, the image displayed on the LCD 18 is projected onto the screen 36 and used as a projector.

FIGS. 9 to 11 show other embodiments of a video camera with a liquid crystal finder according to the present invention. In the embodiment described above, the viewfinder unit 14 was slid to allow the LCD 18 to protrude so as to fit into the projector unit 24, but as shown in FIG. It may also be made to protrude from. When the LCD 42 is housed in the viewfinder unit 38, the LCD 42 is illuminated by the backlight 44.
and the eyepiece lens 46, and is used as a component of the viewfinder unit 38.

On the other hand, when the LCD 42 is made to protrude from the viewfinder unit 38, the projector unit 48 is inserted into the viewfinder unit 38 as shown in FIG.
When attached to the top surface of the LCD 42, the LCD 42 is disposed between the light 50 and the lens 52 and is used as a component of the projector unit 48. Therefore, the image displayed on the LCD 42 is projected onto the screen 36. In the embodiment shown in FIGS. 9 to 11, the knob 40 is raised to
Although D42 is made to protrude from the viewfinder unit 38, the LCD 42 may be made to protrude from the viewfinder unit 38 using other means such as a biasing force of a spring.

Furthermore, in the embodiments shown in FIGS. 9 to 11, L
Although the CD42 is made to protrude upward, it is not limited to this.
42 may protrude laterally. In this case, the projector unit is attached to the battery attachment part of the video camera body, similar to the projector unit 24 used in the previous embodiment.
