摘要： A lens drive unit is configured to move a lens holding frame to a desired position by the engagement between a cam groove of a rotary cylinder and a cam follower of the lens holding frame. The lens drive unit includes a second linearly-moving guide cylinder arranged between the lens holding frame and a first linearly-moving guide cylinder. The second linearly-moving guide cylinder can be moved in the optical a direction with rotation of the rotary cylinder by the engagement of a cam follower of the second linearly-moving guide cylinder with a second cam groove of the rotary cylinder. The lens holding frame is guided in the optical axis direction by the second linearly-moving guide cylinder and moved in the optical axis direction with rotation of the rotary cylinder by the engagement of a cam follower of the lens holding frame with a first cam groove of the rotary cylinder.

摘要： The invention provides a lens barrel, an imaging device and an information terminal device using the lens barrel. The lens barrel includes: at least one lens group which constitutes an imaging optical system; a lens frame which retains the at least one lens group; and a retaining frame which retains the lens frame, the at least one lens group being capable of moving from a collapse position to a photographable position, at least one cam member being arranged between the lens frame and the retaining frame, and tilt of the lens frame relative to the retaining frame being changed by moving the at least one cam member.
