Abstract: In a lens driver apparatus using a linear actuator, spaces for installing a driving coil and a driving magnet are reduced to contribute to making the lens driver apparatus smaller. The present invention relates to the lens driver apparatus including a body that is to be driven and to which a lens is attached, a guide axis to guide and allow the body to be driven to move freely in a direction of the optical axis, a driving coil being flat-wound and fitted to the body to be driven, and a driving magnet being disposed opposite side of the driving coil and along a direction of movement of the body to be driven. In the lens driver apparatus according to the present invention, the driving coil and the driving magnet are shaped in curved forms so as to conform to an outer shape of the lens.

Abstract: A lens held by a lens holding member is to be centered easily correctly. To this end, a guide pin 21 is inserted into a guide hole 22 for positioning the lens holding member 3 with respect to the main body unit of the lens barrel 2 in a plane perpendicular to the optical axis of the lens 4 and for mounting the lens holding member for movement in a direction along the optical axis. If, in this state, each of adjustment pins 26, rotationally mounted on at least three sites on the outer peripheral surface of the main body unit of the lens barrel 2, is rotated, an offset portion 29 of the adjustment pin, offset relative to the center of rotation of the adjustment pin, is rotated, as the offset portion is engaged in an engagement hole 32 of the lens holding member 3, so that the lens holding member 3 on each site is displaced in the direction along the optical axis to adjust the tilt of the lens 4 held by the lens holding member 3.

Abstract: A lens held by a lens holding member is centered easily and correctly by a mechanism in which a guide pin is inserted into a guide hole for positioning the lens holding member with respect to the main body unit of the lens barrel in a plane perpendicular to the optical axis of the lens and for mounting the lens holding member for movement in a direction along the optical axis. Adjustment pins are rotationally mounted on at least three sites on the outer peripheral surface of the main body unit of the lens barrel. If each adjustment pin is rotated, an offset portion of the adjustment pin which is relative to the center of rotation of the adjustment pin, is rotated, as the offset portion is engaged in an engagement hole of the lens holding member. In this way the lens holding member on each site is displaced in the direction along the optical axis to adjust the tilt of the lens held by the lens holding member.
