Abstract: PROBLEM TO BE SOLVED: To provide a lens barrel and an imaging apparatus advantageous to realize miniaturization when the lens barrel is collapsed.
SOLUTION: When judging that a female screw member 1506 is butted against the 1st supporting piece 1510A or the 2nd supporting piece 1510B of a holder 1510 and gets in a state in which it bites at a male screw member 1502, a control part controls the driver of a motor 1504 so that the motor 1504 may reversely rotate with pull-out torque exceeding frictional torque acting on the member 1506 in a state where the motor 1504 is stopped and preventing the movement of the member 1506. Thus, the biting of the members 1506 and 1502 is released.

SOLUTION: A guide mechanism 17 has a guide shaft 14. A drive mechanism 15 comprises an external thread member 1502; a motor 1504 for rotating the external thread member 1502; and an internal thread member 1506 screwed to the external thread member 1502. The internal thread member 1506 reciprocates along the external thread member 1502 by the forward/backward rotation of the external thread member 1502. An end 1506A in the internal thread member 1506 is provided so that it can come into contact with an engagement section 7002 in three groups of lens frames 7. The external thread member 1502 comprises an external thread section 1502A screwed to the internal thread member 1506; and an axial section 1502B extended coaxially with the external thread section 1502A from the end of the external thread section 1502A. A coil spring 1508 biases the engagement section 7002 in a direction for abutting with the end 1506A.

Abstract: PROBLEM TO BE SOLVED: To easily and adequately perform optical axis adjustment of a plurality of lenses by simplifying a structure.
SOLUTION: A rear lens barrel 5 is shifted in a direction approximately orthogonal to the optical axis relative to an intermediate lens barrel 4 in the state a zooming lens 13 is positioned at a wide angle end. While a pair of guide shafts 23a and 23b are being inclined relative to a front lens barrel 3, the optical axis of a focusing lens 18 is adjusted relative to a lens 14 fixed to the lens barrel 4 and thereafter the lens barrel 5 is fixed to the lens barrel 4. Also, the lens barrel 3 is shifted in the direction approximately orthogonal to the optical axis relative to the lens barrel 4 in the state the zooming lens 13 is positioned at a telephoto end. While a pair of the guide shafts 23a and 23b are inclined relative to the lens barrel 5, the optical axis of the lens 9 fixed to the lens barrel 3 is adjusted relative to the zooming lens 13. After the optical axes of the lens 9 fixed to the lens barrel 3 and the zooming lens 13 are adjusted relative to the lens 14 fixed to the lens barrel 4, the lens barrel 3 is fixed to the lens barrel 4.

Abstract: PROBLEM TO BE SOLVED: To displace a lens at a high resolution and to further miniaturize an apparatus. SOLUTION: The unit is provided with a main body 2 of a lens barrel in which a plurality of lenses 7 and 11 which focus the image of an object are arranged in a manner that the optical axes coincide, a lens supporting member 19 which is housed in the main body 2 of the lens barrel and supports at least a lens 11 of the plurality of lenses 7 and 11, guiding shafts 20a and 20b which support the lens supporting member 19 slidably in the optical axis direction, coil spring 33 which energizes the lens supporting member 19 slidably supported by the guiding shafts 20a and 20b toward one side in the optical axis direction, a cam 51 which is abutted to the lens supporting member 19, and a driving motor 53 which is arranged orthogonally to the optical axis and rotationally drives a driving shaft 52 on which the cam 51 is mounted. The apparatus is further provided with a lens driving mechanism 42 which displaces and drives the lens supporting member 19 in the other side of the optical axis against the energizing force of the coil spring 33 according to the displacement of the cam 51 which is rotationally driven by the driving motor 53.
