ABSTRACT:
The invention relates to a viewer for reading and/or displaying information recorded on written or printed tape.
The viewer includes a supporting housing formed with two seats for removably accommodating two motor-driven rotatable spools or reels, one of which carries a roll of written or printed tape material, e.g. paper, wound thereon, the other being adapted to rewind the tape as it unwinds from the first reel. The tape winding/unwinding on/from the reels is controlled by a drive circuitry for operation by the user, e.g. through a push-button control. Above the tape portion extending between the two reels, there is arranged a magnifying lens for reading the information on the tape. Advantageously, the reel-accommodating seats are located on a drawer structure, which facilitates removal and replacement of the reels.
The viewer may be connected to a recorder to create an audio-visual didactic aid therewith.
