Abstract
A body of a camera supporting device according to the present invention is provided with a grip which is shaped so as to permit a one-handed hold, and which incorporates a trigger. A shoe mounting surface is formed on the top of the body, and a shoe is mounted rotatably and detachably on the mounting surface. The shoe is fitted with a camera screw. A ball is fixed on a fixed base which is mounted on a tripod, and is rotatably housed in a cylindrical ball case. The ball case and the body are connected to each other. The ball is held beween an edge of the ball case and a ball retainer by means of the urging force of a compression coil spring. The ball retainer can be moved away from the ball, by means of a link mechanism, by squeezing the trigger, thereby permitting orientation in all directions of a camera mounted on the shoe mounting surface. The camera is locked in position when the trigger is released.
