Abstract

PURPOSE:To enable exact and efficient photographing of an intended place by suspending a photographing device in such a way that said device can restore the attitude by the own weight with respect to oscillation of a balloon and controlling remotely the direction thereof as desired by the rotating and driving device for horizontal and vertical directions. CONSTITUTION:An anchoring rope 8 and a multicored cord 100 are rewound by winding drums 9 and 10 and a balloon 1, a supporting member 4, a supporting frame 42 and a photographing device 52, etc. are lifted to desired altitude in the stage of using the device. Then the balloon of an airship type stabilizes always toward the direction of wind and even if the balloon rolls or pitches, the attitude is early restored by the own weight. The intended object image taken by a television camera 55 for monitoring is received by a television receiver for monitoring of a control device 99 on the ground and if necessary the angle of a camera 54 is matched with the subject by rotating horizontally or vertically the direction of the camera 54 and thereafter the shutter switch of the camera 54 is operated by the control of the device 99 by which the object is photographed.

1 person, cut.

A control device 99 is provided on the ground to remotely control the forward and reverse rotation of the motors 72 and 90, the power on/off of the monitor television camera 55, and the shutter switch of the camera 54.
This control device 99 includes a monitor television receiver that receives an image of the subject captured by the monitor television camera 55. The multi-core cord 100 connected to this control device 99 is wound around a winding drum 101, and the multi-core cord 100 led out from the winding drum 101 is connected to the support member 4, and like the power supply hood 98, the multi-core cord 100 is wound into a holder. It is guided into the casing 43 through the hole 36 of 31 and the inside of the hollow shaft, and is connected to the printed circuit board 95. This printed circuit board 95
are wired to the motors 72 and 90 (not shown),
Cords 102 and 103 for operating the camera 54 and television camera 55 connected to the printed circuit board 95 are connected to the casing 4
The camera 54 and the television camera 55 are connected through a wiring hole 105 provided in the bottom plate 104 of No. 3.

The suspension member 11 is located on the center of gravity of the support frame 42 and photographing device 52, and the support shaft 21 of one joint 12 is located on the center of gravity of the support frame 42 and the photographing device 52.
The other joint 13 is attached to the support member 4 so that the support shaft 21 of the other joint 13 is positioned in the longitudinal direction of the balloon 1.

Next, how to use the present invention will be explained. First of all, at the destination, do you fill balloon 1 with helium gas? After filling the balloon, the holding rope 8 and the multicore hood 104 are unwound from the winding drums 9 and 101, and the balloon 1, the support member 41, the support frame 42, the photographing device 52, etc. are raised to a desired altitude. Since the balloon 1 that has risen is formed in the shape of an airship, it can always be stabilized in the direction of the wind, and even with only one holding line 8, it can be held sufficiently. Even if the balloon 1 swings in the vertical and horizontal directions, the joints 12 and 13 of the suspension member 11 are given an appropriate amount of 7 riction, so the support frame 42 and the photographing device 52 can quickly recover their posture due to their own weight. do.

During this time, the image of the target object captured by the monitor television camera 55 is received by the monitor television receiver of the control device 99 on the ground, so that the object can be confirmed.
If the angle of the camera 54 in the plane is deviated, the motor 72ft is rotated forward or reverse, and the photographing device 52 is rotated forward or reverse around the hollow shaft in the vertical direction to match the angle of the camera with the subject. After that,
Under the control of the control device 99, the shutter switch of the camera 54 can be operated to photograph a subject. At this time, if the support frame 42 and the photographing device 52 are suspended from the rod-shaped support member 4 as in the above embodiment, the attachment position of the shooting line 8 can be separated from the photographing device 52, and the field of view when photographing the subject is It can be removed. If the subject is a slope of a mountain, etc., the motor 90 is driven under the control of the control device 99, and the photographing device 52 is raised horizontally as shown by the chain line in FIG. can do.

Note that a stereoscopic photograph can be created by placing cameras 54 on both sides of the photographing device 52 with a monitor television camera 55 sandwiched therebetween. Further, the photographing device 52 may be configured to use only a video camera to take a picture as a recording and to play it back later.

Furthermore, an infrared film may be used for the camera 54.

Furthermore, the multicore cord 100 and the buckling line 8 may be wound together on one winding drum. The present invention can be modified in various other ways without departing from its basic technical concept.

As is clear from the above description, according to the present invention, since a balloon is used to photograph a subject, it is possible to photograph the subject at a low cost without being subject to restrictions such as air space or earth dragons. In addition, the photographing device is suspended so that it can return to its original position due to its own weight when the balloon swings, and the horizontal rotation drive device and the vertical rotation drive device allow the camera to be oriented in any desired direction. It has the advantages of being able to take accurate pictures and efficiently.
