A projector comprising an essentially horizontal table 1, a projection optics 2 arranged essentially centrally above the table, a light source 3 which is situated above the table and arranged so as to illuminate the table, a deflection mirror 4 for essentially horizontal deflection of the light beaming vertically upward from the table, and a focusing hood 5 which at least partly screens the region between the optics 2 and the table 1 from the surroundings, is designed such that a cover 6A, B is arranged such that it can be laid out over the surface of the table, the upwardly pointing surface of the laid-out cover is light-reflecting, whereas the surface of the table is light-absorbing, preferably matt and black, or alternatively the upward pointing surface of the laid-out cover is light-absorbing, while the surface of the table is arranged to put out light vertically upward. <IMAGE> |
