PURPOSE:To reduce parts in number and to make the titled device simple in constitution by using a cam plate as a lens moving member which moves a lens. CONSTITUTION:This device is equipped with the 1st lens moving frame 27 which moves in optical-axis directions, the 2nd lens moving frame 28 which moves in the optical-axis directions, a groove part 25 which is formed radially about a center of rotation in order to the 1st lens moving frame 27 in the optical-axis directions, and a cam groove 26 which is formed for moving the 2nd lens moving frame 28 in the optical-axis directions. Then, this is equipped with a driving gear 33 which rotates in a plane parallel to the optical axis and has the center of rotation on a line which nearly bisects the movement range of the 1st lens moving frame 27. |
