Abstract
A linear motor table is provided in a lens switching apparatus of a laser repair apparatus. The linear motor table is fixed with respect to a table and a laser oscillator and moves a lens holder in a horizontal direction. Six objective lenses with magnifications different from each other are provided and are held in a lens holder in a row such that the optical axes thereof are parallel to each other. The objective lens placed in the light path of laser light is switched by the linear motor table moving the lens holder. Because of this, a member, such as a lens, can be positioned with high accuracy and if positional shifting occurs, it can be quickly cancelled using a simple mechanism.
