Abstract: An adjusting structure of projector includes a base, a slider, a foot member and a controller. The slider is disposed on the base and has an opening. The foot member is installed through the opening of the slider. One end corresponding to the foot member and the slider is respectively disposed a plurality of groove and a blocker. The top of the controller has an inclined part that presses against an inclined plane on one side of the slider. When a user presses the controller, the inclined part pushes the inclined plane of the slider, making the slider slide along one axis to make the blocker separated from the grooves in a parallel direction. A pressing member moves the projector upward or downward along the foot member to a predetermined location, and then the pressing member is released and returns by the elastic member.

Abstract: An adjusting apparatus comprises a base plate, two pairs of adjusting modules and repositioning module which are accordance with each other, and a light valve clipped between the adjusting module and the repositioning module. The adjusting module controls the light valve to move along one dimension and the light valve can be elastically returned by the repositioning module so that the position of light valve can be adjusted to make the light beam precisely project on the surface of the light valve. In addition, the two modules are placed on the same plane of the base plate so that the two-dimensional adjustment can do on one plane to shrink the thickness and volume of the adjusting apparatus.
