A third projecting lens is formed in the front of a third projector and an inserting hole is formed on the lower portion of the third projector. A guiding plate is combined with the first, second and third projectors, and is transported forward and backward by a driving apparatus. A fixing plate is provided with a parallel guiding hole formed along the length of the third projector and with an inclined guiding hole for guiding the transportation of the third projector. The three projectors can be transported by a driving motor and the operation of the apparatus is very accurate and advantageous.
