テープ５８を引出すものである。As the rotation of the drawer arm 32 progresses, the first guide post 3
8 and the second guide post 40 are separated from the guide plate 56, respectively (FIGS. 3 and 4), and the first guide post 38 is in a state where the bent portion of the first rotating lever 36 and the pull-out arm 32 are in contact with each other. When the magnetic tape 58 is pulled out and the rotation of the pull-out arm 32 progresses further, the bent portion of the second rotation lever 34 comes into contact with the pull-out arm 32 and the magnetic tape 58 is pulled out.
上述の如く本発明によれば、引出しアームの上に２種類

ディング動作を行う利点を有する。As described above, according to the present invention, two types of rotating levers are provided on the pull-out arm, and the rotating angles of the levers when pulled out are different, so that the rotation stroke of the pull-out arm is reduced. The tape remains small while forming a large tape loop, which simplifies the pull-out arm drive system, and the pull-out mechanism itself is also downsized, making effective use of space within the chassis and ensuring stable tape loading operation. Have the advantage of doing.
