ABSTRACT:
The present invention provides an improvement in a card reader type audio visual teaching device. The device employs a card handling mechanism for moving an information card which may contain both audio and visual information, across a record/playback transducing head. A dual track magnetic stripe on the information card carries instructor information or a question on one track to be audibly reproduced by the device which a student can hear through a speaker or preferably a set of headphones. A microphone permits a student to record an attempted repetition or response on the second track. The improvement comprises a multispeed card transport drive mechanism which permits either the student track or both the instructor track and the student track to be driven past the record/playback head at a substantially reduced rate. Additionally, the transport drive mechanism includes a repeat mechanism for returning the card to an initial position. A drive capstan is canted in one direction for forward movement of the card and in an opposite direction for reverse movement of the card while a pair of limit switches serve to limit the travel of the card in the respective directions. A pair of hardened and polished pins are mounted within the card guide track to substantially reduce wear and friction caused by the moving cards.
