Abstract
Abstract A presentation apparatus includes a annular tray mounted on the top of a projector and retaining a plurality of interrelated program slides. A code band is slipped over the vertical wall of the annular tray with a slight pressure fit as the attachment means. The bandheight generally equals the slide tray wall height and the band is divided into columns, one for each slide. Each column is similarly divided into a plurality of code spots. A reader is mounted in fixed operative relation to the slide projector and includes a separate channel to read each code spot in an aligned column. The reader includes an illuminated plastic block with a fiber optic tube for each channel embedded in the block and terminating adjacent the level of one row of code spots. The band can conveniently be formed of paper or a suitable plastic with each code spot defined by suitable intersecting lines. A pre-cut black pressure sensitive tape is provided for selective application to the code spots.
