PERFECTED OPTICAL TOY that is characterized by being formed by two semicajas, of any exterior appearance and joined in any known way, which have coincident and in opposite faces two orifices closed by optical crystals, looking through which the arranged images can be observed in a microfilm disc, which will rotate to present them successively thanks to the fact that said disc is mounted on the face of another rigid one, provided at the ends with a diameter of two lugs that are inserted into corresponding notches of the image disc without the possibility of perpendicular movement to its plane to contain it a projecting piece, disposed at the bottom of the half-box in which the device for driving the rigid disk in the direction of rotational movement is not found.
