Abstract

PURPOSE:To lessen the camera deflection caused by hand deflection by providing a parallel link mechanism swingably supporting a camera in the plane perpendicular to the optical axis of the camera. CONSTITUTION:A camera 1 having a lens 2 is supported by a supporting body 3 through a parallel link 20 comprising links 4 and 5, and the supporting body 3 is connected to a grip 7. The parallel links 4 and 5 whose cross sections are round are formed to square ring respectively and inserted into the through holes of the supporting body 3 and a plate 6. When the links 4 and 5 are swung to the supporting body 3, the camera moves in the X axis direction, but do not have the degree of freedom in the directions of Y axis, tilting axis, and optical axis. Therefore, images are stabilized.
