Improved slide viewer, characterized by being constituted by a box formed by two coupled parts, endowed with an extreme projection for its fixation at the end of a writing element or similar, whose box houses inside a disk of translucent material or transparent with small slides disposed regularly and circularly, whose disk guided in a cylindrical cavity of one of the parts of the box and retained against axial displacements by a circular projection of the other part of the box, can rotate freely and presents a part of its contour accessible from the outside of the box to present this a concave conformation on one of its sides, the disk presenting its rugose or roulette contour to facilitate its operation, this box also having a front opening coinciding with the slides and on its back a translucent window to facilitate the illumination of these.
