PROBLEM TO BE SOLVED: To provide an inexpensive and precise structure for interlocking as to the device which can be used while making a bend between a camera-side lens system and an object-side lens system. SOLUTION: The lenses are usable in a bending state by changing a rectangularly cylindrical intermediate lens barrel 21 with bent one. The lens systems of a lens-tip side lens barrel 22 and a camera-side lens barrel 20 on both its sides are provided with 1st and 2nd lens position detecting means 6 and 9 and 1st and 2nd lens driving means 5 and 8, which are electrically connected by a cable 13 to drive even the 2nd lens 7 according to the position of the 1st lens 4. High-performance optical characteristics are obtained by focus lens driving at two places and neither an increase in the number of components like mechanical interlocking nor a demand for precision is made. |
