FPC board guiding device of the zoom lens barrel

摘要

PROBLEM TO BE SOLVED: To efficiently secure a space where a flexible printed circuit board(FPC board) for connecting a shutter mounted on an advance and retreat barrel and a control part passes and to remove the looseness of the FPC board by guiding the FPC board through a specified path. ;SOLUTION: The FPC board 6 passes the inner surface of a moving lens barrel 19 from an AF/AE shutter unit 21 and is turned back at the trailing end of the lens barrel 19. Furthermore, it is turned back along the outer surface 17h of a straight advance guiding barrel 17 from the leading end of the FPC board introducing groove 17g of the barrel 17, passes through a through-hole 17i, and is guided to the inner surface of the barrel 17 again, then a 3rd U-shaped part 6f and a 4th linear part 6g are projected to the outside the FPC board clearance hole 12k of a fixed lens barrel block 12 and a fixed end 6h is fixed at a fixed part 12m. The FPC bard 6 is connected to the control part 75 through another FPC board connected to the fixed end 6h.;COPYRIGHT: (C)1997,JPO
