ABSTRACT:
A fully automatic speed-reading trainer for which reading speed can be adjusted in a non-step fashion is provided which includes an electric motor designed to drive a relatively large gear, which is one main component of a driving assembly forming a portion of the trainer. Coaxial with the larger gear, on opposite sides thereof, are an eccentric cam and a first pulley. The eccentric cam and pulley are each provided with an axle tube, and each has a coil spring attached thereto, with each coil spring having a free end inserted into respective holes on the larger gear. When the larger gear is rotatably driven in a predetermined direction, one of the springs is tightened about one of the axle tubes, which in turn, dependent upon the rotational direction of the larger gear, drives either the eccentric cam or the first pulley. This driving assembly thereby actuates an advancement assembly, which generates intermittent movement on a pressing board which is driven in a time sequence over predetermined distances to provide viewing of text on pages of a book through a viewing window which is transversely connected to one end of the pressing board. When the driving unit is driven to rotate in a reverse direction, the advancement mechanism quickly retracts to begin a new advancement cycle. The recycling operation is thereby automatically conducted by the trainer.
