The image tilting device according to the preferred aspect of the present invention comprises a casing. The precisely actuating member is housed in the casing to be integrated therewith for precise reciprocation. A driving member contacts to the precisely actuating member for the movement of the actuating member. A light path conversion member is located on the precisely actuating member to convert the light path by a precise movement.
