ABSTRACT:
A card handling apparatus for a teaching machine is operable manually by an operator to load or feed a teaching card in a forward direction at any desirable high speed and to return the card at a predetermined constant speed to record or reproduce an audio information on or from the card without any undesirable wow or flutter.
As the card is manually fed or loaded in a forward direction, the energy for returning the card in a backward direction is charged in a spring means and hence less electric power for operating the apparatus is required.
