Abstract

PURPOSE:To make the title camera light, and to prevent noise and camera-shake from occurring by providing a gyro-stabilizer which prevents camera-shaking at the time of photographing operation in a camera mainbody and providing the rotary surface of the gyrorotor in such a way that it becomes almost parallel to the flat surface of a video mechanical deck. CONSTITUTION:The disk-like gyro rotor 42 is fitted to the lower edge part of a rotary shaft 40 in a drum motor 30 and the rotary surface is caused to be almost parallel to the flat surface of the mechanical deck 28. The diameter of the gyro rotor 42 is formed in almost the same size as that of the mechanical deck 28. The gyro rotor 42 is rotated at high speed by the drum motor 30, so as to act against external force to prevent the rotary shaft 40 which is almost vertical, from being inclined. When a video camera 10 is operated in a grip part 12, the video camera 10 is prevented from causing camera-shake with respect to a photographing angle in a vertical direction and that with respect to the inclination of a photographing screen. Consequently, the camera can be made light and a sufficient stabilizer effect can be obtained without occurring noise.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera with a built-in stabilizer, and more particularly to a camera with a built-in stabilizer that prevents blurring during photographing operations.

[Conventional technology]

2. Description of the Related Art Photographic devices equipped with a gyro stabilizer (stabilizing device) have been proposed in order to prevent camera shake during operation. This stabilizer responds to external force by precession, which is a slow rotation perpendicular to rotational torque caused by the high-speed rotation of a mass object (gyro rotor). That is, since the camera responds to an external force that tends to tilt the gyro rotor axis, the photographing device is maintained so that the photographic screen does not shake.

In addition, for this stabilizer to exhibit sufficient performance, it is necessary to increase the moment of inertia of the gyro rotor, and for this purpose, it is necessary to make the gyro rotor a heavy object and increase the rotation speed of the gyro rotor. Alternatively, it is possible to increase the diameter of the gyro rotor. For this reason, conventional photographing devices include a relatively large stabilizer.

[Problem that the invention seeks to solve]

However, unlike conventional photographic devices, video cameras, electronic still cameras, and the like are required to be smaller and lighter. For this reason, there is a problem in that a large-diameter gyro rotor cannot be easily attached anywhere in a small video camera or the like, unlike in conventional photographing devices.

Furthermore, in a video camera that requires weight reduction, the gyro rotor cannot be made of a conventional heavy object.

Furthermore, increasing the rotational speed of the gyro rotor causes problems such as bearing performance and wind noise.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to propose a small and lightweight camera equipped with a stabilizer having a sufficient anti-shake function.

[Means for solving problems]

In order to achieve the above object, the present invention provides a camera equipped with a video mechanical deck or a disk drive mechanism within the camera body, and includes a shiroscope stabilizer inside the camera body to prevent shaking during photographing operations. It is characterized in that seven gyro rotors are arranged so that the rotating surface of the gyro rotor of the stabilizer is substantially parallel to the plane of the video mechanical deck or the mounting disk surface of the disk drive mechanism.

[Effect]

According to the camera with a built-in stabilizer according to the present invention, the rotating surface of the gyro rotor is made approximately parallel to the video mechanism deck surface within the camera body or the mounting disk surface of the disk drive mechanism, so that The rotor is formed to have a large diameter. Therefore, a gyro stabilizer having a large diameter gyro rotor can be built into the camera body while maintaining approximately the same size as the conventional camera body. Such a Shiloh stabilizer is lightweight, generates no noise, and has a sufficient anti-shake function.

〔Example〕

Preferred embodiments of the camera with a built-in stabilizer according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a partial sectional view of a camera with a built-in stabilizer according to the present invention. As shown in FIG. 1, the main body 11 of the video camera 10 is formed like a caisson, and a hollow grip portion 12 is formed at the bottom thereof.

A photographic lens 14 and an imaging device (CCD) 16 are arranged on the front surface of the video camera body 11 to form an imaging section.

A start/stop button 18 of the video camera 10 is arranged on the front side of the clip section 12. A liquid crystal viewfinder 20 is formed at the rear of the video camera, and the liquid crystal viewfinder 20 includes a backlight lamp 22 and an LCD 24.
It consists of

A mechanical deck 28 is installed horizontally (parallel to the top surface of the camera body 11) inside the video camera body 11, and a drum motor 30 is attached to the mechanical deck 28. The tram motor 30 rotates an upper drum 32, and the drum 32 is composed of a pair of upper and lower drum members. A cassette tape is brought into contact with the outer peripheral surface of the tram 32, and the tape cassette 3
4 is held approximately horizontally within a holder of the mechanical deck 28.

In addition to the capstan motor 36, which has a capstan 38 for running the tape, the mechanical deck 28 includes:
Tape rope ink, a mechanism for forming a tape path, etc. are installed.

Further, the rotating shaft 40 of the drum motor 30 is connected to the mechanical deck 28.
Although it is provided substantially perpendicular to the surface, it is tilted by the amount that the drum 32 is tilted. The rotating shaft 40 extends downward, and a disc-shaped gyro rotor 42 is attached to the lower end thereof, and the rotating surface of the gyro rotor 42 is approximately parallel to the plane of the mechanical deck 28 . The diameter of the gyro rotor 42 is equal to the width of the mechanical deck 28, that is, the diameter of the video camera body 10.
It is formed to be approximately the same size as the lower surface of. Note that the gyro rotor 42 does not need to be directly attached to the tram motor shaft 40, and may be attached via a belt cup link mechanism or a Macnet cup link mechanism. Furthermore, the gyro rotor 42 is not limited to a disc-shaped one, but may be one in which a link member is attached to a wheel.

Further, a battery 44 is housed in the grip portion 12.

According to the video camera according to the present invention configured as described above, the gyro rotor 42 is rotated at high speed by the tram motor 30 during shooting. The substantially vertical rotation axis 40 of the gyro rotor 42 acts on an external force to prevent it from tilting, and when the video camera 10 is operated using the grip section 12, the video camera 10 is free from camera shake due to the shooting angle in the vertical direction.
Camera shake due to the tilt (horizontal balance) of the shooting screen is prevented. Therefore, the tram motor 30 serves as a drive motor for the gyro rotor 42, and the tram motor 30 and the gyro loader 42 are formed as a gyro stabilizer for the video camera 10.

In this case, since the gyro rotor 42 is arranged parallel to the plane of the mechanical deck 28, the area of the mechanical deck 28 required for the video camera can be utilized as much as possible, and the gyro loader 42 can be formed to have a large diameter. Therefore, in order to provide the gyro stabilizer with sufficient functionality, there is no need to make the video camera larger than a conventional video camera, and there is no need to make the gyro rotor 42 a heavy object.
There is no need to rotate it at high speed. Therefore, it is possible to obtain a sufficient stabilizer effect while being lightweight and generating no noise.

Further, the gyro rotor 42 is connected to the shaft 40 of the drum motor 30.
The ladle and drum motor 30 attached to the gyro stabilizer also serves as a drive motor for the gyro stabilizer. Therefore, the video camera 10 does not increase in weight due to the built-in stabilizer.

An experiment was conducted to compare the case in which a video camera according to the present invention holds an object for 5 seconds while taking a picture, and the case in which a conventional video camera without a stabilizer holds the object for 5 seconds in a picture. As a result, the range of blur in elevation and depression angles captured by the video camera 10 was reduced compared to the range of blur captured by a conventional video camera.

Furthermore, the video camera 10 according to the present invention has a single axis (vertical axis).
Although this camera is equipped with a gyro stabilizer, it provides sufficient stability for tilting operations (shaking in the shooting angle in the vertical direction) during shooting, so blurring in the shooting angle in the left and right directions is also prevented compared to conventional cameras.
