ABSTRACT:
An electrical reading guide device for use in typing by a typist is composed mainly of a reading guide plate and a driving apparatus capable of making an up-and-down movement along a strip furrow located at the margin of one side of the reading guide plate. The driving apparatus comprises a transmission device and a pulling device. The transmission device comprises a reversible motor having a shaft with a worm rod attached thereto and a driven gear set having a winding cylinder attached thereto. The pulling device comprises a wire wound around the winding cylinder. When the reversible motor is activated, the worm rod triggers the driven gear set to rotate so as to drive one winding cylinder to wind the wire while another winding cylinder is in a state of unwinding the wire. Therefore, the driving apparatus is capable of moving in a direction in which the wire is wound by the winding cylinder.
