An adjustment module is capable of adjusting a position of a lens of a projector. The adjustment module includes a base, a first tray, a second tray, at least one guide roller, and at least one boundary constrainer. The first tray is slidably disposed on the base along a first axis. The second tray is slidably disposed on the first tray along a second axis substantially perpendicular to the first axis. The lens is fixed on the second tray. The guide roller is rotatably disposed on the second tray. The boundary constrainer is disposed on the base. The guide roller is capable of confining the lens within an image area of the lens by rotatably contacting the boundary constrainer.
