Abstract

PURPOSE:To expand a range able to be controlled remotely by providing a reception section receiving a remote control signal from a remote control transmitter to an electronic view finder section fitted freely turnably. CONSTITUTION:A lens 18 magnifying a picture displayed on a CRT 16 is provided to one end of a case 15 of an electronic view finder 14 and the other end is fitted to a turning section 19 turning the finder around a rotary shaft in parallel with a face of a main body section 12 vertically, the turning section 19 is fitted to a turning section 20 driving the finder around a shaft perpendicular to the main body section 12 horizontally and the center axis of the turning section 20 is fixed to a mount part 21 of the main body 12. Then a photodetecting section 22 of a wireless remote controller is arranged to a lower face of the electronic view finder 14 in the brought-down state. Thus, when a photographer is going to control a remote control transmitter, the section 22 is directed to a desired position. Thus, the photographer attains operations such as start of pickup while being parted from the main body 12 in an optional direction.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a wireless remote control device used for a video camera such as a camera-integrated videotape recorder.
In particular, it is possible to expand the reception range of remote control signals from a remote control transmitter.

(Prior Art) In recent years, camera-integrated video tape recorders (VTRs) have become popular in general households. This camera-integrated video tape recorder uses a wireless remote control device that uses infrared rays to remotely control the camera, allowing it to be used for commemorative photos, wild bird photography, and other photography where the photographer must be far away from the video tape recorder. There is something that can be done.

FIG. 4 is a perspective view showing a conventional camera-integrated VTR using such a wireless remote control device.

In FIG. 4, a main body part 2 of a camera-integrated VTR 1 has a camera part and a VTR part (not shown) inside, and an electronic viewfinder part 3 is disposed on the top surface of the main body part 2.
A camera optical system section 4 is disposed on the front surface of the main body section 2.

On the other hand, the wireless remote control device includes a light receiving section 5 and a remote control transmitter 6. The light receiving section 5 is disposed on the front surface of the main body section 2, and includes a filter 7 provided on the front surface of the main body section 2 that transmits infrared rays, and a light receiving element provided on the back side of this filter 7 that receives infrared signals. It consists of 8. The infrared signal is transmitted from the remote control transmitter 6.

According to such a configuration, the photographer places the camera optical system section 4 of the main body section 2 toward the subject, and then moves the camera optical system section 4 of the main body section 2 toward the subject.
Move further away. After this, when it is desired to start photographing, an infrared signal is transmitted from the remote control transmitter 6 toward the light receiving section 5 on the front surface of the main body section 2.

This allows the photographer to perform operations such as starting photography while staying away from the main body 2.

However, since power is distributed to the light receiving section 5 at the front of the main body section 2, the range that the light receiving section 5 can receive is approximately 60'' to the front.
90'', and the photographer must operate the remote control transmitter 6 within this range.

This is therefore inconvenient for photographing, such as photographing wild birds, in which the photographer cannot necessarily operate within such a range and take pictures.

(Problems to be Solved by the Invention) The above-described conventional wireless remote control device has a limited range in which the photographer can remotely control the main body, which is inconvenient when the photographer cannot operate within such a range.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless remote control device for a video camera that can eliminate the above-mentioned problems and expand the range of remote control.

[Structure of the Invention] (Means for Solving Problem 11) The present invention includes a rotating part attached to the main body of a video camera so as to rotate about a predetermined axis, and one end of the rotating part attached to the predetermined axis. It is characterized by comprising an electronic viewfinder unit rotatably mounted around a rotation axis perpendicular to the axis of shall be.

(Function) According to such a configuration, a part of the electronic view finder is rotated by the rotating section around a predetermined axis, and also rotated around a rotation axis perpendicular to the predetermined axis, so that the photographer can The receiver can be directed to the desired position where the remote control transmitter is to be operated. This allows the photographer to operate the remote control transmitter while being away from the main body in any direction.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
Figures 1 and 2 relate to an embodiment of the present invention, in which Figure 1 is a perspective view of a camera-integrated VTR using a wireless remote control device, and Figure 2 is a cross-section of the light receiving section of the wireless remote control device shown in Figure 1. It is a diagram.

In FIG. 1, a main body section 12 of a camera-integrated VTR 11 has a camera section and a VTR section (not shown) inside, and a camera optical system section 13 is disposed on the front surface of the main body section 12.

Electronic puf finder part 14 to check ms
As shown in FIG.
An RT 16 and a circuit board 17 are built in, and a lens 18 is provided at one end of the case 15 to enlarge the image projected by the CRT 16 and make it visible to the photographer's eyes. As shown in FIG. 1, the other side of the case 15 is attached to a rotating part 19 that rotates up and down about a rotating axis parallel to the surface of the main body 120. Main body part 12
It is attached to a rotating part 20 that rotates left and right around an axis perpendicular to the main body.

The center ring of this rotating part 20 is connected to the mount part 2 of the main body part 12.
It is fixed at 1. The wireless remote control device includes a light receiving section 22 and a remote control transmitter 23. The light receiving section 22 is disposed on the bottom surface of the electronic viewfinder section 14 when the electronic viewfinder part 14 is folded down, and the remote control transmitter 23 is placed toward the light receiving section 22.
Infrared signals are transmitted from the That is,
A filter 24 of a light receiving section 22 that transmits infrared rays is provided on the bottom surface of the electronic viewfinder section 14, and a light receiving element 25 provided on a circuit board 17 (see FIG. 2) is arranged behind this filter 25. ing.

FIG. 3 is an explanatory diagram illustrating the operation of the wireless remote control device having such a configuration.

When photographing a subject (a wild bird) 31 in front by operating the wireless remote control device 22 from diagonally behind the main body 12, the photographer 32 operates the camera optical system section 13 of the main body 12.
The photographer 32 places the camera facing the subject 31 and tilts and rotates the electronic viewfinder part 14.
The user points the light receiving unit 22 at the position where the user intends to operate the remote control transmitter 23. After this, if you want to start shooting,
An infrared signal is transmitted from a remote control transmitter 23 toward the light receiving section 22 of the electronic viewfinder part 14. As a result, the photographer 32 can start photographing and perform other operations while staying away from the main body 12 in any direction.

In the above embodiments, a camera-integrated VTR has been described, but it goes without saying that the present invention can also be used in a case where the camera section and VTR section are separate.

It is also possible to apply it to still cameras and the like.

[Effects of the Invention] As described above, according to the present invention, the photographer can operate the remote control transmitter while being separated from the video camera body in any direction.
