Abstract
An adjusting apparatus for projection comprises a carrier having a central screw hole and three rounded indentations around central screw hole, an adjusting frame having a plane section and a base section, and a holder. The center of the plane section has a circular concave dug a hole with a smaller aperture. A ball bearing is accommodated in the circular concave. The plane section of the adjusting frame has three screw holes corresponding to the rounded indentations. Three angle-adjusting bolts respectively insert through the screw holes to abut against the rounded indentations. Rotating the angle-adjusting bolts relative to each other varies the length of the angle-adjusting bolts calculated from the plane section of the adjusting frame to the carrier. Thereby, an angle adjustment of a mirror is achieved.
