<p>PURPOSE:To eliminate the overlap of a cassette opening part and a tape draw- out member, and to attain the thinning of this device by allowing the guiding groove of the tape drawing-out member to branch it in a tape non-draw-out position. CONSTITUTION:A tape drawing-out part 1 is in the state of A in a tape non- drawing-out position, and a pin 10 and a pin 2 are guided to a branch 4e and a branch 4d, respectively. When the drawing-out part 1 moves in the drawing-out direction, it takes a locus of A B C D, and a magnetic tape is drawn out. On the contrary, in the case of returning it to the tape non-drawing-out position, it takes a locus of D C B A, and in D, one end projecting part 15 of the drawing-out part 1 comes into contact with a cam 4g, is energized counterclockwise centering around the pin 2, and the pin 10 is guided to the branch 4e. In C, a center projecting part 16 comes into contact with a cam 4f, is energized counterclockwise centering around the pin 10, and the pin 2 is guided to the branch 4d. In such a manner, the drawing-out part 1 is drawn out roughly in parallel as A B, and the overlap on a plane to a cassette opening part is obviated.</p> |
