Abstract

PURPOSE:To prevent a flexible printed circuit board (FPC) from breaking and a defect in zooming operation from occurring by providing a lens barrel with the FPC which connects a fixed terminal to a motor electrically, and almost eliminating the position shift between the motor and a fixed frame. CONSTITUTION:When a zoom ring 4 is rotated around an optical axis, the rotation is transmitted to a cam frame 7 by a zoom pin 11. This frame 7 rotates and an external helicoid frame 12, a 1st lens group frame 17, a 2nd lens group 19, and a 3rd lens group 20 move forth and back in the direction of the optical axis. Respective lens groups L1, L2, L3 and L4 of this lens barrel moves as shown by A, B, C and D by rotating the ring 4. Then the movement quantities of the lens groups L1-L4 at the time of moving from the wide-angle side W to the telephoto side T are '0' for each (z), (y), (x). Namely, the lens barrel is longer in the axial length of an output gear than the movement quantity (x) of a step device 29 fixed to a lens group frame 20 by zooming operation to the fixed frame 2. Then the motor 44 does not move at all in zooming as to the fixed terminal 48.
