[Prior Art] Conventional tripod platform structure, particularly when mounting a camera on the platform, a knob formed by projecting a male screw is rotatably provided on the back surface of the platform, and this male screw is mounted on the top of the platform. When the camera is mounted on the platform, the male screw is attached to the female screw provided on the bottom of the camera.

Also, a camera mount is detachably mounted on the platform, a male screw is rotatably mounted on the mount, and one groove is provided on the head of the male screw, and a coin such as 10 yen is provided in this groove. This is done by fitting the female screw provided on the bottom of the camera to the male screw.

[Problems to be Solved by the Invention] In the conventional tripod platform structure, a knob formed by projecting a male screw on the back surface of the platform is provided, and the male screw is projectable or reciprocable on the upper part of the platform. In the case where the camera is screwed to the male screw, there is a problem that it takes time to attach and detach the camera.

That is, when mounting the camera, the knob has to be rotated and screwed each time, and moreover, it has to be screwed after being accurately positioned on the female screw provided on the bottom of the camera. Not only was it required, but skill was required.

Also, when removing the camera from the platform, the same operation as when mounting the camera had to be performed, which was very troublesome.

Especially in recent years, video cameras have become popular, and if you want to take pictures with a tripod and continue to take pictures with the camera in your hand, you have to rotate the knob each time to release the screwed state, so you can take pictures quickly. There was a problem that I could not move.

Also, there was a similar inconvenience when moving from handheld photography to tripod photography.

Also, on the platform, a mounting base is detachably installed on the camera, and a male screw is rotatably mounted on this mounting base, and the camera is screwed to this male screw, when shifting from tripod shooting to handheld shooting, Since the mounting base is simply removed from the platform, the inconvenience of shifting from the tripod-based photography to the handheld photography is eliminated.

However, when mounting the camera, the male screw must be rotated by a coin, and the male screw must be accurately positioned on the female screw provided on the camera before the male screw is rotated. Not
It also required skill.

Further, even when the camera is removed from the mount, the same operation must be performed using the coin each time, which is very troublesome and troublesome.

Furthermore, since it is screwed with a coin when the camera is attached, not only is the operation complicated, but it is difficult to tighten the male screw, and therefore the screw is often not completely screwed, and the camera comes off during shooting. Existed.

Furthermore, if there is no coin in hand during shooting, there is a problem that it becomes virtually impossible to mount the camera.

For this reason, there has been a strong demand for the development of a camera platform that allows the camera to be completely and easily attached to the camera platform and that allows the camera to be easily and easily removed from the tripod even when handheld.

[Outline of the Invention] The present invention was made in order to meet the above-mentioned demand.
It is an object of the present invention to obtain a tripod head structure in which the camera can be completely and easily attached to and detached from the tripod head, and the camera can be easily and easily attached to and detached from the tripod during handheld photography.
