Abstract
Abstract Herein disclosed is a language teaching apparatus of card type, in which a teaching card having a visual information and at least one magnetically recording band is repeatedly returned in an automatic manner or in accordance with the will of the student so that not only the programmed question but also the basic and student's answers may be repeatedly reproduced for confirmation or comparison. The language teaching apparatus includes as customary a body formed with an upright guide slot, in which the teaching card is allowed to run horizontally back and forth, card drive capstan for operatively driving the card when in contact therewith, magnetic reproduction heads for magnetically reproducing, when in contact with the recording band of the card, a programmed audio question which is recorded in the recording band, mechanical linkage for bringing the card drive capstan into its operative position, electric circuits for actuating the mechanical linkage, and manual control buttons for controlling the electric circuits. The language teaching apparatus is characterized by the provision of two limit switches cooperatively actuatable in response to its engagement with and disengagement from the running card for defining the running range of the card and for controlling the electric circuits together with the manual control buttons, and by the provision of a repeat switch for reversing the direction of movement of the card so that the audio information may be reproduced once more.
