Abstract
Abstract In a magnetic recording and/or reproducing apparatus of the cassette type which is adapted to employ a small-sized tape cassette, the magnetic tape in the cassette is extracted to be wrapped about and from the both sides of a guide drum to a predetermined angular extent by means of a pair of extracting means. The extracting means have a vertical pin and an inclined pin arranged rotatably about the vertical pin in order that such means may travel in a restricted space of the apparatus. After achievement of the extraction of the tape, the inclined pin is adapted to rotate in such a direction that the tape is further wrapped around the guide drum, so that the tape loading is achieved. A pinch roller is so provided that it travels on the same path as the extracting means at least from the starting position to the predetermined position also in such restricted space. When the extracting means return to the initial position, in order to prevent the slack of the tape, a driving mechanism for the fast forward and rewind is utilized to wind speedily the tape.
