目的とするものである。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional camera turntable device described above, the cable is repeatedly twisted inside the rotary shaft by repeating the rotation (reversal) operation within 360 °, which causes disconnection. There was a problem. The present invention solves such a conventional problem, and an object of the present invention is to provide an excellent camera turntable device that can remarkably extend the service life of a cable until the cable is broken by reversing the camera. To do.

利点を有する。なお、上記実施例ではガイド棒を有して
いるが、ガイド棒を省略しても良い。Embodiment FIG. 1 shows the structure of an embodiment of the present invention. In FIG. 1, reference numeral 1 is a cable for connecting a camera having a spiral portion, which is connected to a camera 2 and clamped at two places by a clamp member 3. A terminal block 4 connects the camera connection cable 1 inside the turntable to an external cable.
Reference numeral 5 denotes a platform for fixing the camera 2 at an arbitrary angle and further fixing it to a hollow rotating shaft 6. 7 is a motor and a gear
The rotating shaft 6 is rotated via 8a and 8b. Reference numeral 9 is a guide rod that regulates the position of the spiral portion of the cable 1. Next, the operation of the above embodiment will be described. In the above embodiment, when the motor 7 is driven, the rotary shaft 6 rotates via the gears 8a and 8b, and the camera 2 fixed to the platform 5 rotates. Then, by rotating, the diameter of the spiral portion of the cable 1 connected to the camera 2 expands and contracts, and the expansion and contraction amount changes depending on the rotation angle. Thus, according to the above embodiment, the camera 2
The stress received by the cable 1 due to the rotation of the cable 1 is absorbed as a minute bending deformation of the spiral portion of the cable 1, so that the life of the cable 1 can be extended. Although the guide rod is provided in the above embodiment, the guide rod may be omitted.
