DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a photographing device such as a video camera.

BACKGROUND OF THE INVENTION With the spread of video tape recorders in recent years, there are many opportunities to use video cameras to take pictures, and there is a demand for a video camera that can perform stable camera work with less image blur without using a tripod. There is.

An example of the conventional photographing device mentioned above will be described below with reference to the drawings. Conventionally, this type of photographing device is shown in FIG.
The structure was as shown in the front and side views in Figure 4. That is, there is a rotor case 1 that houses a rotor that rotates at high speed at the center as a directional gyro, and this is supported by a horizontal gimbal 3 with left and right horizontal axes 2, and the horizontal gimbal 3 is further supported with a vertical gimbal 5 with left and right gimbal axes 4. is supported by Similarly, a rotor case 6 at the center of the vertical gyro is supported by a horizontal gimbal 7 and a vertical gimbal 8, and a video camera 9 and the like are installed on the rotor case 6. Therefore, by rotating the directional gyro and vertical gyro at high speed, the video camera 9 can be used even when shooting in shaking conditions.
is stable and allows you to obtain captured images with little blur.

Problems to be Solved by the Invention However, the above configuration uses a gyro that rotates at high speed, which increases the size and weight of the device, so the entire device must be installed and used. The problem was that it lacked maneuverability.

Means for Solving the Problems In order to solve the above problems, the photographing device of the present invention includes a camera body having a photoelectric conversion means for converting an optical image from a photographing lens for photographing a subject into an electrical signal, and a yawing rotation means provided at a lower position (or upper position) of the main body to rotatably support the camera body in the yawing direction; and a yawing rotation means provided at a lateral position of the camera body to move the camera body and the yawing rotation means in the pitching direction. The pitching rotation means is rotatably supported by the pitcher, and the pitching rotation means is held by a grip.

Effects Due to the above-described configuration, the present invention does not use a large and heavy gyro as in the past, so it can be easily configured to be small and lightweight, allowing the photographer to use it hand-held, and the camera body can also be attached and detached. This enables highly mobile shooting, and allows camera work with reduced image blur without using a tripod.

Embodiment Hereinafter, a photographing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of the main parts of a photographing device according to an embodiment of the present invention, in which a camera body 11 has a photographing lens 12 on the front surface for photographing a subject, and The optical image is converted into an electrical signal by an image sensor 13 such as a CCD provided on the focal plane of the photographic lens 12. This electrical signal is converted into a predetermined video signal by the video circuit 14 and transmitted to the camera terminal 16 provided on the bottom surface of the camera body 11. The rotating plate 17 combined with the camera body 11 is rotatably supported by a ball bearing 20 press-fitted into the intermediate plate 19 about approximately the center of gravity of the camera body 11 and the rotating plate 17. A ring-shaped magnet 22, which is magnetized as required, is adhered to the lower surface of the moving plate 17 via a back plate 21 made of a magnetic material. Further, a stator winding 24 is bonded to the upper surface of the intermediate plate 19 at a position facing the magnet 22 via a stator flat plate 23 made of a magnetic material. At the center of the rotating plate 17,
A rotating plate terminal 25 that can be contacted with the camera terminal 15 is provided, and a video signal etc. supplied to the camera terminal 15 can be transmitted. Furthermore, a ring-shaped magnet 27 that is magnetized in a predetermined manner is adhered to the right side of the intermediate plate 19 via a back plate 26 made of a magnetic material, and the fixed plate 19 is
A stator winding 30 is bonded to the left side surface of the magnet 8 at a position facing the magnet 27 via a stator flat plate 29 made of a magnetic material. The intermediate plate 19 has a shaft portion 31 on the right side, and a ball bearing 32 press-fitted into the fixed plate 28 rotates the center of gravity of the camera body 11, rotating plate 17, and intermediate plate 19 as a center. It is rotatably supported. Note that the intermediate plate 19 is stably held by the attraction force between the magnet 27 and the stator flat plate 29 without falling off.

The fixing plate 28 is coupled to the hand grip 34, and a fixing plate terminal 36 and a grip terminal 37 are provided on the right side surface of the fixing plate 28 and the left side surface 34 of the hand grip 34, respectively, so as to be able to come into contact with each other.

The hand grip 34 is also provided with a zoom switch 43 for electrically zooming the photographic lens 12, a VTR connection terminal 44, and a recording switch 45 for controlling the recording operation of the connected VTR. FIG. 2 is a block diagram showing electrical connections. A control circuit 46 built in the intermediate plate 19 is connected to an angular velocity sensor 47 provided on the rotating plate 17, and receives a signal from the angular velocity sensor 47. Accordingly, an actuator 48 constituted by the magnet 22, stator winding 24, etc. is driven. The angular velocity sensor 47 detects camera shake in the yawing direction when rotating in a horizontal plane, and the control circuit 46 ensures that the output of the angular velocity sensor 47 always approaches zero.
By controlling the actuator 48, camera shake in the horizontal direction can be reduced. Similarly, a control circuit 49 is built into the fixed plate 28, and drives an actuator 51 composed of a magnet 2, a stator winding 30, etc. in response to a signal from an angular velocity sensor 60 provided on the intermediate plate. The angular velocity sensor 5o detects camera shake in the pitching direction rotating in a vertical plane, and the control circuit 49 is configured so that the output of the angular velocity sensor 6o always approaches zero.
By controlling the actuator 51, camera shake in the vertical direction can be reduced.

The power supply 62 supplied to the VTR connection terminal 44 is supplied to the intermediate plate 19 via the grip terminal 37 and the fixed plate terminal 36, and then to the rotating plate terminal 2 via the through holes 38, 39, 40.
6. It is supplied to the camera body 11 via the camera terminal 16.

The operation of the photographing apparatus configured as described above will be explained below. Camera shake in the horizontal and vertical directions is detected by the angular velocity sensors 47 and 50, the actuator 48 is driven by the side dividing circuit 46, and the actuator 51 is driven by the control circuit 49 so that the outputs of the angular velocity sensors 47 and 50 always approach zero. By controlling the camera body 11, even if the hand grip 34 held in the hand shakes due to camera shake or the like, it is possible to take a stable image.
This video can be recorded on a VTR (not shown) connected to the TR connection terminal 44.

As described above, even when the photographer takes a picture hand-held, it is possible to obtain a photographed image with little blur, and the camera has excellent mobility.

In the above embodiment, the case where the yawing rotation means is provided at the lower position of the camera body has been described, but it is essentially the same even if it is provided at the upper position of the camera body.
