<p>PURPOSE:To detect surely the start and the terminal of a tape, by moving a tape end sensor to different positions so that the tape end sensor faces the tape in the tape loading state and the tape loading release state. CONSTITUTION:When the play mode is set, a loading disc 3 is turned counterclockwise. The first engaging arm 31c of the fourth turning lever 31 is pressed by an engaging piece 3e on the loading disc 3 and is turned clockwise against the charging of a torsion spring 34; and when the torsion spring 34 passes the change point, the charging direction of the torsion spring 34 is inverted, and the first engaging arm 31c is turned clockwise by charging and is stopped in the position where it is engaged with a stopper 33c. Thus, a tape end sensor 29 in the take-up side is turned at about 90 deg. from the position of rapid-traversing and rewinding states and faces a tape 4.</p> |
