PURPOSE:To reduce the load by a cable when a lens barrel rotates in horizontal and vertical directions fixing two cables for transmission and reception signals at two spots symmetrically to the left and right sides of the lens barrel and detouring the intermediate part between the fixed parts largely on the tip side. CONSTITUTION:The coaxial cable 15 from an optical system block 2 is fixed on both the base end 1a of a lens barrel 1 and the side surface 23a of the fixing support frame 23 of a biaxial actuator 3, respectively, by first and second fixing parts 16a and 16b. Next, the intermediate part 16c between the fixing parts 16a and of a cable 16 is drawn by detouring the part 16c largely from the oblique upper direction to the lower direction of the optical axis F of the lens barrel 1. By P type cable guides 38 and 40 at two upper and lower portions of the side surface 23b of the frame 23, the intermediate part 16c of the cable 16 is guided in freely movably in a length direction along the side surface 23b. Two cables from transmission and reception signals exist from a block 2, one cable fixes and guides in the same way symmetrically to the cable 16 and the lens barrel 1. Thus, the load by the cable when the lens barrel 1 rotates in horizontal and vertical directions is reduced. |
