DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated recording device with a monitor, which is provided with an integrated monitor for easily confirming the photographing state of a subject.

[0002]

2. Description of the Related Art The appearance of a conventional general camera-integrated VTR is shown in FIG. In FIG. 12, reference numeral 101 denotes a camera unit, 102 denotes a VTR unit to which a tape cassette can be attached and detached,
Reference numeral 103 denotes a viewfinder for displaying a monochrome or color liquid crystal display for a monitor, 104 denotes an eyepiece, and 105 denotes a microphone.

Since the display screen size of the liquid crystal display panel in the viewfinder 103 is as small as about 1 inch square, an image magnified by an eyepiece is viewed through an eyepiece 104.

As described above, the small size of the liquid crystal display panel in the viewfinder 103 has an advantage that the cost of the liquid crystal display panel can be reduced. However, on the other hand, there are the following disadvantages.

[0005] That is, since the display screen of the liquid crystal display panel is viewed through the eyepiece 104, it can be seen only with one eye, making it difficult to see. The photographer positions his / her eyes away from the camera-integrated VTR main body. The viewfinder 103 cannot be used to monitor the shooting condition at the position. The viewfinder 103 is literally dedicated to obtaining the angle of view for shooting by the photographer. When shooting and recording the subject as a subject, another monitor having a large screen size is required, but this has a disadvantage that it cannot be easily realized.

Against this background, in recent years, there has been a demand for a camera-integrated VTR with a monitor that allows the user to easily check the photographing situation of a subject by moving away from the camera-integrated VTR main body without passing through an eyepiece. Is coming.

For example, a camera-integrated VTR with a monitor TV disclosed in Japanese Patent Publication No. 4-6154 discloses a VTR unit 201 and a monitor unit 202 which are vertically stacked as shown in FIG. VTR unit 2 on the bottom of 202
01 together), and the camera unit 203 is detachably held on the long side surface of the monitor / VTR unit thus formed into an elongated rectangular parallelepiped. .

In the electronic camera disclosed in Japanese Patent Application Laid-Open No. 1-106581, as shown in FIG. 14, a monitor main body 301 and a camera main body 302 are rotatably connected around a common shaft 303. The configuration is as follows.

[0009]

However, both of the above-mentioned publications disclose the lens unit 20 on the distal end surfaces (surfaces perpendicular to the longitudinal direction) of the camera units 203 and 302.
Since 4,304 incident light planes (imaging planes) are provided, the monitor unit 20 is used in the most frequently used normal photographing state, that is, in a state of photographing a subject in front of the operator (see FIG. 13).
The camera unit 203, 302 is rotated by 90 ° relative to the camera unit 2, 301, and the image is taken in the most unstable state in terms of shape and weight balance.
There is a problem in that a large load is applied to a connection portion between the camera unit 2 and 301 and the camera units 203 and 302, and the connection unit is easily damaged.

In the normal photographing state, the operator grips the camera units 203 and 302 with the palm facing upward, and the wrist of the operator's hand holding the camera units 203 and 302 is twisted. Therefore, it is inconvenient to use because of the burden on the wrist.

Can take and record while visually checking the VTR 500 with the monitor and the camera-integrated VTR 500 itself.

FIG. 11 shows a state of face-to-face photographing.
In this state, the monitor / VTR unit 1 is moved from the storage position shown in FIGS.
By rotating 0 by 180 °, the photographing surface of the lens unit 28 and the liquid crystal display panel 17 are oriented in the same direction. At this time, the rotation of the camera unit 13 and the monitor / VTR unit 10 relative to each other by 180 ° activates the inversion detection switch 89 to drive the image upside-down inversion IC of the liquid crystal drive board 48 and the liquid crystal display panel 17. , The image can be projected upside down.

Then, the monitor-integrated camera-integrated VTR 500 in such a state is placed on a table 90 or the like, and the photographer separates from the monitor-integrated camera-integrated VTR 500 and remotely controls the remote control transmitter 91. The remote control includes zoom adjustment, recording start,
Pause (pause), stop, etc., an infrared remote control signal from the remote control transmitter 91 is received by the remote control signal receiving unit 20 of the camera-integrated VTR 500 with monitor, and a predetermined control operation is performed.

In this face-to-face photographing, the photographer takes his / her own as a subject and performs photographing and recording while displaying the image as an upside-down image on the liquid crystal display panel 17. Here, since the display screen size of the liquid crystal display panel 17 is relatively large, the photographer can visually confirm the photographing state of the subject satisfactorily if the photographer is slightly away.

The camera-integrated VTR 500 with monitor
Is set on a tripod, and the rotating mechanism 14 is configured to be driven by a motor, and the motor is driven by remote control by a remote control transmitter 91 so that the camera unit 13 and the monitor / VTR unit 10 May be remotely controlled.

Further, in the above-described embodiment, a description will be given of a case in which the image displayed on the liquid crystal display panel 17 is automatically inverted by rotating the camera unit 13 and the monitor / VTR unit 10 by a relative rotation of 180 °. However, the switching may be performed by a manual switch or a remote control so that the user can arbitrarily invert the image up and down. It is apparent that the present invention is not limited to the above-described embodiment by providing an automatic mode, a manual mode, or the like.
