Abstract

PURPOSE:To prevent an operating error from occurring when a video camera is shifted to other place while a picture appears by changing over automatically to picture appearing standby condition when a video camera main body is lifted up by a holding part. CONSTITUTION:A part of a changing-over driving piece 3 supported turnably by an axis 5 at a supporting piece 4 fixed to a camera main body 1 is protruded at the external part the camera main body 1 and a sash cord 7 for holding is fitted. When the camera main body 1 is suspended with the sash cord 7, a changing-over driving piece 3 is turned in the clockwise direction against the force of a spring 6, and interrupted by pushing a switch 8. The switch 8 is inserted serially with an operating switch 8 to change over manually the standby condition and the picture appearing condition, and when the switch 8 is interrupted, the supply of the electric current source to a deflecting circuit 10 of the image pick-up tube of the video camera, a deflecting circuit 11 of a Braun tube and a video signal processing circuit 12 is interrupted and the standby condition is shifted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video camera device, and is particularly characterized by a switching device used to switch the video camera body from an image output state to an image output stun state. It is.

BACKGROUND OF THE INVENTION Conventionally, in video camera devices, the heater of the image pickup tube is kept in a heated state (standby state) so that a good image can be obtained immediately after the start of operation.
When necessary, the video tape recorder (V
(TR) or an electronic viewfinder built into a video camera to quickly shift to an image output state in which a video signal is output. That is, the device is configured to be able to shift from a standby state to an image output state, or vice versa, by operating a switch.

Problems to be Solved by the Invention However, in such a device, a switch must be changed in order to shift from an image output state to a standby state, and for example, when performing continuous video recording, etc. - Even after stopping the video tape running on the VTR, there are cases where you forget to change the switch and the video signal, which is the recording signal, continues to be output from the video camera, which consumes the limited power supply battery. Something happened. Additionally, in the standby state, the VTR is generally configured so that it will not operate even if the VTR operation button on the video camera is operated, and it can only be operated when the image is being output, so the VTR can be moved to another location. Even in cases where the VTR is held in the hand with the image on, the user may accidentally touch the operation buttons of the VTR, causing malfunctions.

Means for Solving the Problems In the video camera device of the present invention, a changeover switch provided on the video camera body for switching between the image output state, image output standby state, and The video camera is linked to a holding part of the tool, and is configured so that when the video camera body is lifted by the holding part, the video camera is automatically switched to an image output standby state.

Function The present invention has a changeover switch that is linked to the handle of the video camera body or the holding part that is a hanger.
When the user finishes filming or recording with the video camera,
When moving, the video camera is held by the holding part and at the same time the changeover switch is driven by the video camera's own weight.
This will put the video camera into standby mode,
The trouble of operating a switch can be saved, and it is possible to prevent the video camera from being left in the image outputting state and operational errors that occur due to this, and it is possible to eliminate wasted power consumption and malfunctions.

Embodiments Hereinafter, video camera apparatuses according to embodiments of the present invention will be described with reference to the drawings.

1 to 3 are diagrams showing a video camera device according to an embodiment of the present invention, in which 1 is a camera body, 2 is an eyepiece of an electronic viewfinder incorporating a cathode ray tube for monitoring video signals; Reference numeral 3 designates a switching drive piece that is rotatably supported on a support piece 4 fixed to the inside of the camera body 1 on a shaft 5, and is biased with a counterclockwise rotational force by a spring 6. A part of this switching drive piece 3 is connected to the camera body 1.
A hanging cord 7 for holding is attached to protrude from the outside. That is, as shown in FIG. 3, when the camera body 1 is suspended by the hanging string 7, the switching drive piece 3 spring 6
It is configured to rotate clockwise against the force of , and push the switch 8 to shut it off.

The switch 8 is inserted in series with an operation switch 9 for manually switching between a standby state and an image output state, and when this switch 8 is cut off, the deflection circuit 1o of the image pickup tube of the video camera and the cathode ray tube are switched off. The power supply to the deflection circuit 11 and the video signal processing circuit 12 is cut off, and the system enters a standby state. That is, even if the operation switch 9 remains in the image output state, the switching drive piece 30
When rotated, it automatically enters the image output standby state.

Effects of the Invention As described above, according to the present invention, by simply holding the video camera body with the holding portion, it is possible to drive the switch provided inside the video camera body and change the image output state to the image output standby state. This eliminates the hassle of conventional switch operations, eliminates wasted power consumption caused by leaving the video camera in the image output state, and eliminates operational errors that occur due to the video camera remaining in the image output state, such as when the video tape is It is possible to prevent the video tape recorder from being driven by accidentally pressing the recorder drive button.
