Also 63 is the antenna of the receiver 9, and 64 is the antenna of the transmitter 13.

[0020] Next, the operation of the above structure will be explained.

[0021] For example, when photographing a panoramic view of a building, use the helicopter 1 as the control receiver 6. Stop above the building, then look through the finder 56 and check the building. Ru. At this time, to adjust the shooting angle, directly rotate the monitor TV 16 to the desired angle. In response to this rotation, the monitor camera 11 is linked. i.e. finder When the image receptor 16 in the horizontal state is rotated downward while looking at the horizontal axis 46, the horizontal axis 46 rotates. This is detected by the vertical angle detection device 47 via a pair of gears 48, and this signal is It is input to the photographing operation transmitter 15 via the control unit 51.

Also finder 56 For example, if you turn the monitor TV 16 facing forward at a 45° angle, the front The vertical axis 43 rotates, the horizontal angle detection device 45 detects this, and this signal is sent to the control unit 50. is input to the photographing operation transmitter 15 via. And the signal from this transmitter 15 The motor 28 is operated via the receiver 9, and the rotation speed sensor 31 operates the motor 28 via the receiver 9. The rotation angle is controlled, and the upper and lower parts of the mount 22 and 25 as well as the monitor camera 11 and steel The camera 12 can be oriented horizontally as desired. In this embodiment, for example, the rotation angle Set a pair of gears so that the rotation angle B of the upper and lower parts 22 and 25 of the mounting base is twice that of A. 48.

[0022] In this way, while looking at the viewfinder 56, move the monitor in the direction you want to see the TV 16. After moving the monitor camera 11 to determine its angle, press the shutter button 57. The signal is input to the photographing receiver 9 via the control unit 58 and the photographing operation transmitter 15, and then The shutter actuator 40 is actuated via the control unit 59 to allow the still camera 12 to move forward. Photographs of the buildings will be taken. Note that the still camera 12 has automatic film feed. It has a built-in device (not shown) that allows multiple images to be taken in the same manner as above. is now possible.

[0023] Even if vibrations occur during the flight of the helicopter 1, the vibrations can be removed with a shock. The monitor camera 11 and still camera 12 vibrate because it is absorbed by the quad absorber 23. This allows you to see accurate images and take accurate photographs. Wear. Similarly, the vibrations that occur when the helicopter 1 lands are also applied to the shock absorber 23. It can be absorbed more. In particular, shock absorber 23 has a small hole that acts as an orifice. It has a damper function using 23E, which can alleviate vibrations.

You can easily set the mounting positions of 45 and 47.

[0025] Moreover, monitor camera 11 and still camera 12 rotate horizontally together with leg 2. , legs 2 do not obstruct the images of monitor camera 11 and still camera 12. It is possible to accurately grasp buildings.

[0026] Note that the present invention is not limited to the above embodiment, and the rotation drive device may be belt driven. Various modifications are possible, such as a gear drive. Also shock absorber The damper may be of any type as long as it has a damping effect, and the damping effect is achieved by a gas-filled cylinder. This can also be done by means of da, etc.

[0027]
