APPARATUS OF CONTROLLING DIRECTION FOR CAMERA

摘要

PURPOSE: A direction control device for a camera is provided to adjust the direction of a camera two-dimensionally using a one-dimensional driving device. CONSTITUTION: A direction control device for a camera comprises a connection bar unit(110), a ball joint unit(112), a 4-bar unit(100), and a one-dimensional motor. One end of the connection bar unit is connected to a spot on the backside of a camera, which corresponds to the center of a lens. The ball joint unit includes a linear motion guide for guiding three-dimensional rotational and linear motions to the connection bar unit. The 4-bar unit comprises first through third straight links and one triangle link, wherein a first vertex(P) of the triangle link is connected through a ball joint to the other end of the connection bar unit. The first straight link is a fixed link whose one end is connected to a rotary shaft(A). The second straight link is connected between a second vertex(B) of the triangle link and the rotary shaft. The third straight link is connected between a third vertex(C) of the triangle link and the other end(D) of the first straight link. The one-dimensional motor provides torque for the second straight link through the rotary shaft.
