ABSTRACT:
An audio-visual teaching machine so made that, when any one of a plurality of independent visual teaching contents respectively appearing in a plurality of windows is pressed with a finger, an audio teaching content corresponding to the pressed visual teaching content may be automatically reproduced so as to be able to efficiently teach with a simple operation. This teaching machine is used together with a teaching card having a plurality of visual teaching contents on one surface and a plurality of magnetic tracks containing audio teaching contents corresponding to the respective visual teaching contents on the other surface. Until the teaching card is correctly set in the teaching machine, a buzzer will continue to sound. When the visual teaching content appearing in the window is pressed with a finger while the teaching card is set in a correct position, a lamp will be lighted to illuminate the window.
