<P>PROBLEM TO BE SOLVED: To provide a high-magnification, small lens barrel and optical instrument. <P>SOLUTION: The position in which an FPC 12 for inputting/outputting an electric signal to/from a CMOS 602 is pulled out from a sensor lens barrel 6 is disposed in the area 1 of four areas sandwiched by a pair of diagonals of the CMOS in a plane perpendicular to an optical axis Oa. A first actuator for moving a fifth group lens barrel 5, holding a fifth lens group L5 movable in the direction of the optical axis and closest to the CMOS, in the direction of the optical axis, and a second actuator for moving the sensor lens barrel, holding the CMOS, in the direction of the optical axis are disposed in at least two areas of the remaining three areas. A pair of guide shafts by which the movement of the fifth group lens barrel is guided in the direction of the optical axis and a pair of guide shafts by which the movement of the sensor lens barrel is guided in the direction of the optical axis are arranged so as not to overlap the first actuator, the second actuator and an electric wiring in the plane. <P>COPYRIGHT: (C)2012,JPO&INPIT |
