DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera apparatus which has a VTR deck unit and a camera unit and can record video signals on a cassette tape.

[0002]

BACKGROUND OF THE INVENTION Applicants have previously described VT as shown in FIG.
A video camera device is proposed in which the R deck unit (2) and the camera unit (3) are arranged on the same horizontal plane in a posture at the time of shooting.
(Japanese Patent Application No. 2-46415). In the video camera device,
At the time of photographing, the apparatus can be held in a stable horizontal posture by attaching the right hand to the end of the VTR deck section (2) and the left hand to the camera section (3). When used as an image reproducing device by connecting to a television, the device is a stationary VTR.
Since it has the same flat cabinet shape as the deck, the stability in the stationary state is good.

[0003]

In the above-mentioned video camera apparatus, the eyepiece (48) of the electronic viewfinder (47) is positioned at the position of the operator's eye while holding the apparatus with both hands during shooting. In addition, it is necessary to provide a cassette lid opening / closing mechanism, operation switches, and the like in the holding portions of the VTR deck unit (2) and the camera unit (3). Therefore, the electronic viewfinder (47) was installed so as to protrude from the upper surface of the cabinet. However, this causes a problem that the device becomes thicker by the height of the electronic viewfinder (47).

It is an object of the present invention to provide a video camera device in which the electronic viewfinder is arranged on the same plane as a VTR deck and a camera, so that the device can be further flattened. Another object of the present invention is to facilitate photographing of a low-angle subject in a video camera device in which the electronic viewfinder is arranged on the same plane as the VTR deck and the camera as described above.

[0005]

In the video camera apparatus according to the present invention, an electronic viewfinder (4) is installed on the same plane as the arrangement surface of the VTR deck section (2) and the camera section (3). The electronic viewfinder (4) is provided with a camera unit.
(3) an image display device main body (40) extending in a direction substantially perpendicular to the optical axis (31) of the objective lens (30), and an image light beam emitted from the main body (40) is directed to an image observation direction of an operator. The camera unit (3) is provided with a window for observing an image reflected on the reflection mirror (44). In the video camera device according to the present invention, the reflection mirror (44) and the image display device main body (40) can be integrally rotated about the longitudinal axis of the image display device main body (40), and Includes a first posture in which the direction of reflection of the image light beam by the mirror (44) is directed in the direction opposite to the objective lens (30) along the optical axis of the objective lens (30), and the optical axis of the objective lens (30) It is operable to switch to a second posture directed upward along a vertical plane, and the camera unit (3) displays an image reflected on the reflection mirror (44) in each of the first and second postures. A window for observation is provided.

[0006]

[Effect] In the photographing posture in which the VTR deck section (2) and the camera section (3) are held with both hands, the electronic viewfinder is used.
The image light beam emitted from the image display device body (40) of (4) is bent by approximately 90 degrees by the reflection mirror (44), passes through the image observation window, and enters the operator's eyes. Also, the image display device body
In a video camera device in which the (40) and the reflecting mirror (44) are integrally rotatably mounted, the normal shooting posture, that is, the observation direction of the operator with respect to the camera unit (3) coincides with the optical axis of the objective lens (30). In this case, the reflection mirror (44) and the image display device main body (40) are set in the first position. In this state, the image light emitted from the image display device main body (40) is reflected by the reflecting mirror (44) in the opposite direction to the objective lens (30), passes through the observation window, and enters the operator's eyes. I do. When photographing a low-angle subject, that is, the objective lens (30)
When the video camera device is held at a low position in a posture in which the optical axis of the camera is directed substantially in the horizontal direction, and the operator views the camera unit (3) downward, the image display device body (4
0) and the reflection mirror (44) are set in the second position. In this state, the image light beam from the image display device main body (40) is reflected upward by the reflection mirror (44), passes through the observation window, and enters the operator's eyes.

[0007]

In the video camera apparatus according to the present invention, the VTR deck section (2), the camera section (3) and the electronic viewfinder (4) are arranged on the same plane.
The apparatus can be flattened as compared with the conventional apparatus. Further, by providing the image display device main body (40) and the reflection mirror (44) in a rotatable manner, it becomes easy to photograph a low-angle subject.

A pressing member (92) protruding toward the (90) side penetrates the plurality of protruding pieces (93) into the flange (95) and is engaged therewith. Thus, the pressing member (92) can reciprocate within a certain range in the cylinder axis direction of the holder (94) in a state where the holder (94) is prevented from being pulled out. Further, a compression spring (91) is arranged in the holder (94) and urges the pressing member (92) to the left.

Therefore, by pushing the electronic viewfinder (4) rightward from the state shown in FIG. 3 against the urging mechanism (9), the shaft (66) of the lock member (65) is brought into contact with the rail groove (61). 4), and finally fits into the lock concave portion (64) as shown in FIG. 4, whereby the electronic viewfinder (4) is locked.

When pulling out the electronic viewfinder (4), the operation knob (8) is slid against the spring (7) to disengage the shaft (66) of the lock member (65) from the lock recess (64). Let it. As a result, the main body storage portion (42) of the electronic viewfinder is urged to the left by the urging mechanism (9) to move slightly, and the shaft portion (66) of the lock member (65) is moved straight (63). You will get up.

When the electronic viewfinder (4) is further pulled out, the shaft (66) of the lock member (65) slides on the linear groove (63), and in this process, the main body housing (42) is pushed by the biasing mechanism. Separated from (9), the shaft part (66) of the lock member finally comes into contact with the wall surface of the circumferential groove part (62) as shown in FIG. From this state, when the mirror storage part (43) is rotated upward,
The shaft (66) of the locking member slides on the circumferential groove (62), and the eyepiece
