1. A pair of tape pull-out pieces (7) (7a) are slid along a guide groove (12) on a chassis (1) to pull out a magnetic tape from a loaded cassette and to a cylinder (13). In a magnetic recording / reproducing apparatus equipped with a tape pull-out mechanism for guiding, the tape pull-out mechanism is connected to a motor (21) and slides back and forth and a slider (2) is connected to the slider (2) and can be rotated forward and backward. A drive wheel (3) pivotally supported by the chassis, a rotating wheel (4) meshing with the drive wheel (3) and pivotally supported by the chassis so as to be capable of forward and reverse rotation, the rotating wheel (4) and the tape It is composed of a link mechanism (6) arranged between the pull-out piece (7) and a drive wheel (3) and a rotating wheel (4).
Are continuous with the spur gears (33) (42) formed at the beginning of engagement of the two wheels (3) (4) and the gears (33) (42),
At the beginning of the tape pullout, the spur gears (33) (42) are integrated with the logarithmic gears (34) (41) with a radius of gyration that reduces the speed immediately before the completion of the tape pullout, at the same speed as when meshing.
